Note: This story was dynamically reformatted for online reading convenience. I had always found dominant women to be a favorite fantasy of mine. After years of playing in the single's vanilla scene, I came across several Femdom magazines when I was visiting my local porno shop. I bought them and spent many nights jacking off to the pictures and stories within. After a couple of years of this I mustered up the courage to contact one of the professional Dommes listed in the S&M newspapers. While my experience there was good, I found myself increasingly drawn to the medical scenes. The average lady in the magazines only dabbled in these fantasies and rarely had much equipment to complete the image. I remained in this rut for a while until one day I saw an ad on the Internet highlighting the serious nature of this particular Domme. Amongst the primary areas of interest was heavy medical play. I had to contact her through her E-mail address and waited for several days to get a response. When I did, she asked for my phone number and said she would call me the following evening. I rushed home that night and fixed a light dinner. I tried to watch TV, but my eyes kept going to the clock in anticipation. Finally at 9:30 my phone rang and a pleasant woman's voice was on the other end. We had a nice ten-minute talk in which she asked me about my interests and experience. I told her that I wish to delve more deeply into the medical scene and that I would do everything to make sure she got as much out of the relationship as I could provide. She told me that while she did charge for her services, it was only to retain the level of control she demanded and that she had enough money to walk away from the scene forever if she so chose. But, she enjoyed it and wanted to find a few select clients to play with, while ignoring the common rabble. She asked me what my plans for the weekend were, and if I had the required money to do a full scene. I told her any plans I had prior, could be cancelled and that the money was as far away as my bank. That being established, she told me to come to her house the next evening(Friday) and we would go over my profile in depth and see if I would make the final cut. Finding that I had passed the first screening,, I found myself outside her door in a light rain. I rang the bell, but got no answer. I waited another five minutes and rang again. This time the door opened and there waiting for me was a very attractive brunette in her mid-thirties. She was dressed in a skirt and blouse and could easily be confused for a number of businesswomen that worked downtown. She apologized about not hearing the bell the first time, and asked me into her living room. "Come in, I'm Katherine. When in public, calling me by my name is fine, when in session, I will let you know how to address me," she smiled. There a comfortable seat was waiting for me. As I sank into the chair, she asked what I wanted to drink. "A whiskey, "neat" would be great!" She smiled as she handed me the drink and I noticed she had a glass of white wine for herself. We did a little small talk for fifteen minutes. She chuckled at my jokes and knew about everything I mentioned in the outside world. This was a highly educated, sophisticated woman with a good sense of humor. She told me that she had gone two years to Med school before leaving to join the family business after her father's incapacitation. While she never went back, it was always an area of interest to her. "I especially liked the control over the male patients I had," she mentioned with a hint of a wicked smile. I told her that I was serious about having her get a lot out of the relationship and that if there was something she wanted to try I did not mention, the fact that it was not high on my personal list, in no way should prevent her from trying it. This seemed to please her and she mentioned that a strong sense of curiosity on my part matched well with hers, and would go a long way toward having us both getting what we wanted. With that she told me that the time had come for the questionnaire and that I should leave my money on the table, assuming that I passed the final test. "You see, you will not have any pockets from this point on to carry it around with.' "Now strip and go into the bathroom and shower. I had taken a shower prior to going over to her house, but saw little upside in arguing. I took a quick shower and was greeted by her with a towel and a blindfold. I was led down a hallway into a room and placed in comfortable chair. Once seated, I was tied to the chair by soft cotton ropes and a fan was turned on so that I would remain cool. My legs were spread apart and the gentle breeze, as well as my situation, began to work its magic on my cock. "Well then, let's start with a series of questions to see what your over all condition and illnesses are." Her soothing voice said. "Do you have any medical conditions I should be aware of?" " My knees suck, but otherwise I am in good health." "No heart issues?" "Nope." "Good. Then we can move on to what your likes, dislikes, perversions and desires are." " Let me know if these are things you have tried and liked, tried and did not like or were neutral on. Also if you have not gone down one of these roads yet, let me know how the idea appeals to you," she said in a firm but sexy tone. As she went through a list of everything from general Femdom fantasies, to specific medical, I felt the gentle tickle of an ostrich feather being run over my body. Special attention was given to my now throbbing cock. While I tried to pay attention, and answer as logically as I could, this was a major distraction and I know I answered more positively to the kinkier, more extreme of the ideas she put forward, simply because I was so horny. The examine took over twenty minutes, and by the end, I was sweating despite the fan blowing on me. I also was so randy, with my prick like oak, that I could not even be truly sure what I had said. Finally she stopped and told me that because of my nasty thought and behavior, I would have to go through a complete medical examine to discover why I had such perverted desires and lack of proper respect for women. I had been wrongly conditioned by society and needed to get my mind "right.' Further, since it was my fate to be at her beck and call and to fulfill every one of her desires, I would have to go through proper training in many of the proper "sub" regimens. First, she must test my reactions so that the medical examine, could be most beneficial. Toward that end, she took off my blindfold and led me into her "dark" room. My balls were tied up and weights attached. I was then laid down face first on a bench with a hole in it where the ball weights could be dropped through. My feet were tied together and my arms were tied over my head. I was stretched out on the bench and the blindfold was put back into place. Also, ball-gag was jammed into my mouth. A strap was run around my midsection and I was left to consider my condition. I heard Katherine move about the room, and I tried to prepare myself for the pain I knew was to come. "Well, I think we will warm you up and see what levels of pain your backside can endure." I felt I series of light taps with a leather paddle, and realized that I was in no position to do anything if the pain became intense. I was spread out and could barely move at all. While the pain was light I knew enough from my past that it was sure to get stronger. I wasn't wrong! Are the seconds ticked by, her strokes increased in severity and soon I was squirming, but was totally unable to avoid the blows. Now I had told her that I was really a wimp when it came to having my ass beaten, but what is light to some is heavy to others. The blows now delivered sharp stings with each stroke, and while my screams could be heard through the gag, I had no idea how much longer she would keep this up, or how I would be able to take much more. Suddenly, it was over. "It seems that at least on this matter, you were not lying. You are barely above the vanilla client stage in pain tolerance on your ass." "But since you said you could take high levels of pain on other parts of your body, there is still hope for you," she said ominously. "Now go shower again, and wait for me to come to get you," she instructed as she quickly unbound me. I went into the bathroom and showered quickly, while my mind raced over what might be in store. "What the Hell had I told her?!" After I dried off, I stood in the bathroom and looked over several of the unusual items in the room. There was a shower as well as a bathtub. The tub had metal handles on both ends and on each side. It did not take much of an imagination to envision these being used as possible aids in bondage. There was also a portable toilet, as is used by invalids. In the shower there was a ring centered in the middle of the ceiling. This too would allow for ones arm being suspended from above. While I was tempted to look into the drawers, I knew that Katherine could come back at any time and that she could walk in on me, as there was no lock on the door. Just then she appeared and my caution was rewarded. She was wearing hospital whites and heavy soled rubber nurse shoes that made no sound as she walked. This struck fear in me as it meant that she could move around the room, when I was blindfolded and I would never know when she would appear and/or strike. But gawd she looked amazing! In her hand was a typical hospital gown that she threw me and told me to put on. I also put on paper slippers that had elastic bands that ran around the ankles. "Please follow me. I am Doctor Kat." I was led into a large room with a gyno-chair, a hospital bed and an OP table. There were a number of sterile cabinets and pieces of medical equipment. "Please get up in that chair and we will start the procedure," she said in a matter of fact tone. I got up in the chair and was pleased to see that it was a European style chair that had behind the knee supports, instead of the usual American stirrups. This meant that I could remain in the chair without getting muscle cramps. I made a comment to this effect, and she smiled and said that she only wanted me in pain when SHE wanted me in pain. As I settled into the chair, she quickly applied straps to my wrists and strapped in my legs. While there was not much in the way of elaborate bondage going on, it was very effective. "We will have to see what shape you are in as well are prepare you for more serious procedures." With that she threw my gown up over my shoulder exposing the lower part of my body. "Well first things first. If we are going to do proper experiments, we have to be sure that everything is sterile. This means that no hair can remain in the operation area. So we have to shave you entirely in this area," she said giving my balls a sharp tug. "Firstly we will remove the large amounts of hair with this shaver," she said as she took an electric razor to my pubic mound. When this was whittled down to nubs, she put away the electric razor, and walked over to a sink and ran some warm water into a bowl. Dropping several rags into the water, she brought them over to the chair and set them on a side table. She then opened one of the cabinets and brought out a bottle of menthol shaving cream. She applied a large amount on her gloved hand and smoothed it over my cock, balls and asshole. Next she took out a new razor and slowly started to shave me. The menthol stung a little where the previous shaving had taken place. She worked from north to south, starting with my pubes and then working over my cock and balls. As she reached this area, I sprung to life, and she exacerbated the issue by gently stroking the shaft as she moved the foam around. I moaned, and she asked if I was in pain. "If so, I can stop!" "No, I am fine!" When she finished shaving, she took a towel and roughly wiped off the remaining shaving cream. I saw her open a bottle of alcohol and soon my balls were burning as she applied the stinging solution. "As I have to examine your backside, we need to get these out of the way," Katherine said as she tugged on my balls once again. She produced a leather parachute harness and strapped it around the base of my scrotum. As she strapped it into place, she attached a string to the ring at its bottom, and tied the other end to bar hanging over the chair. The string was slack, but not for long. She went over to the wall and pressed a button, causing the bar to rise toward the ceiling. My balls were being stretched, but before it became too painful, she stopped the advance. She then attached the bar to another pole that was at the head of the chair. This caused my balls (and cock) to be pulled away for my asshole and over my belly. It also caused the balls to be further stretched. "We need to see if there are any blockages in your backside, and if so make sure you are cleaned out before we get to the difficult experiments," explained the doctor. With that, she put on two surgical gloves and applied lubrication to them. She spread the lube around my asshole and slowly inserted one finger. Gently moving this finger in and out, she continued until I relaxed enough for her to insert one more. She duplicated the process, and went on to insert three and finally four fingers inside me. She slid her hand in and out up to her knuckles, but could not get any further inside. "If we are going to have you fully stretched, we will have to do several relaxing exercises and employ several other stretching techniques. Also, you are not fully clean there and to avoid infection, we need to clean you out, first," my doctor said in a matter of fact tone. "I will prepare your enema and this will allow us to have a much more productive session." She moved over to the sink and I saw her take out a large enema bag for the cabinet. The water was running and I saw her get a double Bardex out of a drawer and lube it up. Walking over to me she inserted the nozzle slowly; first one balloon, then the second. She attached to pumps and inflated each balloon inside me. Initially, there was not too much pressure and the balloons felt wonderful pressing against my prostate. She gave my cock a squeeze and pre-cum oozed out. She moved back over to the sink and filled the open-ended bag with what appeared to be about three quarts of water. I then saw her put in a good squirt of peppermint soap. Doctor Katherine brought the bag over to the chair, where I remained strapped in, and hung it on an IV stand. Next she attached the bag's nozzle to the end of the Bardex. "Now relax," she cooed, and clicked the latch starting the enema. The warm water flowed steadily into me and I concentrated on using my muscles to send it deep up inside of me. I knew that if it stayed in the lower colon, I would soon be in a lot of pain with cramps. I closed my eyes and concentrated on doing what I could do to make this as bearable a process as I could. The doctor slowly rubbed my belly, occasionally giving my cock a stroke. I knew I could easily come if I was not careful, what with the pressure on my prostate, but she was too skilled to let that happen, and would stop before we reached the crisis stage. She removed her hands from me and went over to a drawer. "Lift your head," she said and secured a surgical mask over my nose and mouth. "This will help you relax and hold the enema for as long as I think is required." She lifted the edge of the mask and slipped a ball of cotton that was permeated with poppers. Soon a warm detached feeling came over me, but in the back of my mind, I feared that the enema might leak out if I was to relax too much, and the poppers were heading me in that direction. It was if she read my mind, for suddenly, I felt the balloons once more expanding inside of me. It was painful, but the poppers caused me to feel it in a detached way. Well, there was not going to be any leaks now! The enema continued to pour into me until the bag went flat. The Doctor rubbed my belly and a distinct sloshing sound could be heard. Suddenly a cramp gripped me and I pulled against the bondage. I felt I was going to explode but the enema had nowhere to go. "We don't want this to enema to wear you out too much, so I am going to let you expel it." She undid the straps and lowered chair so that I could easily get down. I was led, doubled over, to the toilet and once seated, the air was let out of the Bardex balloons. They popped out of my ass and were followed by floods of enema. I rocked in place and wave after wave of pain came as the jets of water came out of me. "I want you to stay here for ten minutes and expel as much as you can, but I am going to give you a cleansing enema to clean out the soap; so it really does not matter that everything comes out this time, because it all will on the next round. It is just that it might give you a little more room to fit the next enema into you. It is your choice," she said with not a little malice. I stayed a full fifteen minutes before there was no more cramps. I cleaned up and strolled into to examination room. Doctor Kat was preparing a rolling table of equipment which looked to have several items that I had never seen before. She draped a cloth over most of the items and told me to get back into the chair. I settled in and was quickly once more put into bondage. Her gloved hand applied a cool gel to my asshole and I felt the Bardex put back inside. It was pumped up once again, but this time even more fully. "Since we are going to do so many things to you , we will make sure that nothing is left inside your digestive tract. This can only be accomplished by a very large cleaning enema." She moved over to the sink and began to run the water. The IV stand was rolled next to it and she took a huge enema bag out of a cabinet. It had to hold at least a gallon! Doctor Katherine hooked up the bag and began to fill by pouring the water into the open top bag out of a pitcher. The steam rose out of the top of the bag, indicating that the water was very hot. When the bag was filled to the bulging point. She turned off the water and turned to me. "We will let this cool just a bit, but I want to prepare something to help take you mind off the cramps." She opened a cabinet and took out a full mask that had a hose attached to the mouth area of the front. " I want you to relax, so I will put this on you and start an aroma therapy." The mask was pulled on over my head and secured. The hose , for the moment was left unattached and allowed me to breath freely through it. Doctor Kat then brought over a re-breathing devise that could be attached. It had a system in which air was drawn through whatever liquid was pour into the catch basin. The smell of whatever liquid was added would permeate the air breathed through it. " I was thinking of adding rose water, but since I had all those drinks earlier, it would be a shame to waste all my golden elixir. So warm piss it is for you!" she said with an evil grin. She sat on her rolling stool, hiked up her Doctor's coat and pulled up her skirt. Her magnificent pussy was revealed in the dim light and she took the pitcher and placed it under her pussy. A moment later jets of piss splashed against the pitcher wall and began to fill it up. A relieved expression came over her face as she emptied her bladder, and she smiled once again as she patted herself dry with a Kleenex and rose to begin to put the offering into the re-breathing devise. She closed it off once it was filled and attached the end of the hose coming from my mask to the devise. Immediately, my oxygen was cut in half and I had to breath deeply in order to get enough. This sucked the air through the piss and I was hit with the strong smell. While it was acrid, my cock seemed to respond to the effect and began to swell. Dr. Kat lightly ran her fingernails over the underside of my cock and the swelling increased. "Well this is interesting, it seems you like being at the mercy of a woman and will allow yourself to be subjected her will. I think I will have to make it clear just what that entails," she said with a serious stare. " But first the cleaning. This enema will include a soap to make you squeaky clean." " You took longer than I instructed to expel, so I assume that you need another cleaning enema; so another peppermint soap enema it is." I saw her pour a yellow liquid into the enema bag and stir it with a metal rod. " This might cause cramps, but then you might not be sure if it is the soap or the volume. Here goes." She released the valve on the enema and the flow began immediately. It was hot be not so much that I was burned. It did cause me to suck in air and the piss smell seemed to surround my head. While it flowed into me, Dr. Kat rolled my belly back and forth allowing the enema to climb higher into my system. After two minutes, the cramps started and she gave the Bardex another pump. She looked me in the eyes and cooed that it was so nice to see a man suffer so. I glanced over at the bag and was horrified to see that it was only just past the half way point. 'Suck it up sweetheart, you need to suffer to get the proper attitude." I did what I could to draw the water up into my system, but the cramps continued to get stronger. The bag began to slow its reduction, indicating that the water had no where to go. "You will not be allowed to release this enema until it is all in you. I can wait forever, can you?" With that, I once more tried to draw the water up into me and the bag began to flow once more. A minute went by and it finally emptied. I wanted to tell her that I would do anything to relieve myself, but the mask prevented any conversation. I turned my head and moaned and when I looked back, she was leaving the room. "Be back in a few," she chirped. I lay in the chair and concentrated on keeping the cramps down, but it did little good. I screamed into the mask and tears began to well up in my eyes and each cramp came on, each stronger than the next. I gasped for air but the restricted flow and the strong piss smell left me lightheaded. Five minutes later she walked into the room and asked if I was ready to go to the toilet. I nodded emphatically and she began to unstrap my bondage. The mask was removed and I sucked a huge breath of fresh air. "Now do not spill a drop on the way to bathroom. " I was finally free and I slid out of the chair. A cramp doubled me over and I quickly shuffled to the toilet forty feet away. I sat down and the air was released from the Bardex. The balloons exploded from my ass as the pressure of the water behind it demanded to be released. I sat on the toilet rocking back and forth as the gallon of water exploded out of me in waves. For fifteen minutes I sat as the trauma of the experience left me temporarily spent. I slumped forward and sat there until she came into the room. "Take another shower and meet me in the exam room." I showered and stood at the door of the bathroom trying to muster the courage to continue the session. I finally entered the room and Dr. Kat indicated that I should once more climb into the chair. My legs were strapped in and my wrists were cuffed. A chain ran under the chair and was attached to the cuffs. Two padlocks were used to prevent me from any attempt to shake off the chain. The length of the chain prevented me from bringing either hand any higher than a level just below my ass. " Now we need to do some experiments upon your reproductive organ." " What type of experiments?,"I asked. " Where ever the test takes us", she smiled and said. " I will put on some music to relax me as I do not want to slip while doing this delicate procedure. Neither I, nor you, can ill afford a slip, so I must prevent you from disturbing me. Best to gag you once again!" She pulled a ball gag into my mouth and secured it. I noticed that is had a hole running through the middle of it which for the moment allowed me to draw in more air. She turned on a New Age CD and rolled over another small table that was covered with a white cloth. Removing it I saw a wide array of clamps and sounds. She ran her finger up the underside of my cock and I became fully stiff. She looked away for a moment and returned her gaze to my genitals. She held up a Wharton Pinwheel to the light so that I could see all the sharp points and brought it down to the base of my cock. I jumped as the needles stuck into my flesh and slowly she ran it up to the swollen head. I squirmed but at the same time I felt an intensity that I had not known before. Dr. Kat ran the wheel up and down the shaft and with each pass shifted slightly so that a new area was abused. Taking one hand and squeezing the shaft, she ran the wheel over the head. The sensation was a strange combination of sharp sticks and a dull ache. I tried my best to recoil from the assault, but it did no good. " It seems you are very sensitive, but the question is, "can you control your own actions? We will try a little stimulation and if you can stay flaccid, then we know that you are in control of yourself, if not...." She gave a ominous glare. She put down the Wharton pinwheel and picked up a large hand vibrator. Dr. Kat reached down and plugged it in and turned it on. The hum coming from the ball head increased as she brought it into contact with the head of my penis. I knew that I needed to try to stay soft, but she expertly ran it to the most sensitive parts and I felt the blood begin to engorge it. I was getting stiffer by the moment. " Come on! Be good and stay soft!" she said with a bit of mockery in her voice. It was no good though and she knew it. I was throbbing and would spurt soon; not that she would allow that. " I'm sorry, but you need severe treatment and behavioral adjustment. We will have to have you experience pain so that you can better control your weak body." She opened a drawer of a wheeled cabinet and took out a dozen clothespins. She took the skin below the head of my cock and pinched it to get a good amount of flesh to attach the pin to. It was attached and bobbed in the air as my cock jumped. Another pin was attached below this one. The process was repeated until six pins were stacked on the underside of my cock. " Now for your balls." She took the remaining clothespins and applied them. " Now that does not look like you have enough decoration, I will be right back." She walked out of the room and a she left I stared at the swaying rhythm of her hips. The pinching of the pins hurt but was bearable for the moment. She was gone for a couple of minutes and during that time the pain seemed to steadily increase. She reappeared and took another handful of clothespins out of a bag and began to rapidly attach them to my balls. Soon almost two dozen pins decorated my cock and balls and I was squirming. "Do they hurt?, she said in a mocking coo. We won't keep them on long, because I am only using them to awake your pain receptors in that area." After another minute, she reached down and took a hold of the pin just below the head of my cock. She squeezed the ends and the blood flowed back into the abused area. The pain was much worse now than before. I screamed into my gag. "Oh, I know that that has to hurt but we cannot leave them on forever. We need to do much nastier things to you." She took each clothespin off but at a leisurely pace. I rolled my head from side to side in agony, but to no good effect. Finally the last clothespin was removed and I lay there moaning. Dr. Kat moved around the room and gathered a few more items. I saw her raise a spray bottle toward my bobbing cock head and pump several sprays of alcohol on the head and urethra area. It burned and I bounced as much as I could to cause air to evaporate the alcohol as quickly s possible. She smiled cruelly down at me and I saw her pick up a catheter in a paper package. She peeled it open and sprayed it as well before lubing its length. The tip was brought to my penis head and slipped inside. Slowly it was inserted. I felt it slide down my shaft and hit the prostate. She withdrew it a bit and once more pushed it down my cock. It hit the prostate once more, causing me to jump, but this time it slipped inside and into my bladder. Dr. kat had clamped the tube shut so no flow came up the catheter. I saw her pick up a syringe and draw sterile water into it and then pump it into the second opening of the catheter. It filled up a balloon inside my bladder and with a tug it was pulled against the end of the urethra, preventing anything from moving down the shaft. The balloon inside my bladder made it feel that I had to urinate. I moaned a bit and Dr. Kat looked at me sympathetically. I am sure you need a rest and perhaps some relief from your bladder. You will not explode for a while and I think rest is the first thing on the agenda. She hit a button and the chair reclined using an electric motor. " I am afraid that you may be right, Mike, the remains of the enema will work its through your bladder. But since I cannot release you, I will have to think of something other than letting you go to the toilet." She cocked an eyebrow and with an evil sneer said, "I got it." She moved to a cabinet and took out a tube. It had a pointed plug-like end that inserted into the tube of the catheter. The plug had an opening that allowed fluid to flow through it. She took the other end of the tube and inserted it into the hole in the plug wedged into my mouth. " I do not want you to suffer, so let's relieve some pressure in your bladder." She undid the clamp on the catheter tube and immediately I saw urine flow down it. It was heading toward my mouth and there was nothing I could do to avoid the inevitable. A moment later, warm piss sprayed the back of my throat. The flow was steady and I swallowed quickly. " There, isn't that better?" " Now we are going to work on your reproductive organ and see if you were lying when you answered those questions." My mind went into overdrive trying to remember what she might be talking about. She reached and grabbed the shaft of my cock and slowly began to stroke it. I became rock hard and was sure that I would spray cum everywhere, despite the catheter inside of me. I thrust my hips forward trying to trip the orgasm, but she puled her hand away and walked out of the room. A minute of so passed and she returned with a electric box with several attachments. A loop was placed over my cock and balls and attached to the box. I saw her adjust the level and switch it on. Initially I felt nothing, but as she turned it up I felt a tingling followed by a sticking pain. This advanced to a pulling feeling that stung and felt a little as if I had been hit in the balls. Waves of electricity shot through me and lifted me off of the table. Dr. Kat turned it down and I collapsed panting into the respirator. " That was nice, wasn't it?" I had no idea what reaction she was looking for, but I did not want it turned on again. No good, as she switched it on once more and slowly increased the power. I pulled against my restraints and moaned into my gag. Tears were beginning to well up in my eyes and I looked pleadingly at her, trying to have her stop. She looked at me and shut it off. "Let's let you get rid of the remainder of that enema and so we can help you relax." She undid my restraints and led me to the bathroom. I sat on the toilet and the bardex had the air let out of it. I took another ten minutes to get to the point where I felt nothing inside. I could not pee a the catheter and gag were still in place. " Are you done? If so, clean up and come back in," I heard from the other side of the door. I freshened up a bit and came back in the room. "Get back into the chair." She expertly put me back in to the bondage and pulled a light over my groin. Turning around, she took a plug off of the table and attached the wire coming out of it to the electric box. She put on a fresh glove, covered it with gel and ran it over and into my asshole. The plug was placed against the opening and gently pushed in. It popped into place and my sphincter closed around the base. She smiled and turned on the juice. Tingling advanced to a pulling feeling and soon I felt as if I was going through a combination of having my guts pulled out and a thousand needles plunged into my colon. I bucked and bucked. Sweat poured out of me and soon I was screaming into the gag. " I think that it is time for you to relax a bit, so I am going to let you rest." The level was lowered to a point where it was a steady pulse. She left the room and turned off the light. I was bathed in darkness. The electric shock was low enough where it was rather pleasant. The smell of urine was still strong but combined with the electricity was producing an effect upon my cathetered cock. I was rigid when Dr. Kat came back into the room twenty minutes later. "Just as I thought, I leave you alone and your mind turns to filth. We will have to do something to take your mind off of antisocial behavior." The chair was adjusted backwards so that my head was fifteen degrees below my chest. My legs were spread wider when the cradles holding them were adjusted outward and back. This left my groin exposed and my ass wide open. The doctor took my balls in her hands and rolling them slowly in her fingers said, "Let's get these out of the way." She attached a parachute harness around the base of the scrotum and snapped it into place. A ring hanging from the bottom of the harness was attached to a rope hanging from a pulley in the ceiling. The other end of the rope looped through another pulley and hung ten feet away against near the wall. Kat walked over to a cabinet and took out a black ball with a hook on it. While I could not tell from this distance, I assumed it was made of lead and weighed about 2-3 pounds. She hung it from the other end of the rope and my balls were pulled up and away from my ass. She took another weight and hung it from the same loop. Now the pulling on my ballsack was enough that it felt like my balls were being tightly squeezed. " Now we have room to work. I think you should have some poppers to help you relax during this next phase." She detached the tube running to the gag. Then she took the gag out of my mouth and replaced it with a small mask and screwed on an attachment which all the air is drawn though a single ¾ inch hole. She doused a cotton ball in poppers and shoved it into the opening. Immediately the rush of the drug hit my head. I felt her run her fingers up and down my cock shaft and it throbbed as she did so. She abruptly stopped and opened a drawer to a rolling cabinet by the gynochair. I saw a steel speculum taken out and she spread lube all over the two tongues. Next the cold gel was put on my asshole and several fingers were pumped inside spreading the lube within. I felt the cold metal tongue touch my hole and slowly it was inserted inside of me. The edges seemed sharp as it moved past my outer defenses, but soon it was inside and any momentary pain stopped. Dr. Kat squeezed the handles and I felt the speculum open inside of me. "Let's open this good and wide so that we can give a good look inside," she said as she screwed the speculum into a fixed open position. I saw her take a long cotton swab and dip it into a solution inside of a bottle. " This is cinnamon oil and I am afraid it will burn, but it is the best thing we have to check your reactions. It is a good thing that you cannot move, because this will hurt." She cocked her eyebrow and inserted the swab through the opening of the speculum. I felt her run it around the inside of my colon and soon I felt the burning that she had promised. She was right! I burned and could not do anything to reduce the pain. I sucked air through the poppers and was caught somewhere between total agony and limbo. She slowly ran her fingers up and down the underside of my penis shaft and I throbbed and I lay in pain. Just as the pain from the cinnamon oil began to subside, she repeated the process once again. " I want to desensitize you a bit as I am going to have to expand you and I do not what this to be worse than it has to be." She left the room and I lay panting in my painful bondage and in near delirium. I saw her return with a box of surgical gloves and then remove the speculum. She took the cotton swab, dipped it into the oil and swab my asshole. It also burned intensely and she popped it in and out covering the entire area. She put on a glove that reached to her mid forearm and with the other hand squeezed lube gel all over the hand. " I am going to put my hand up inside of you and when I do I will totally own you," she said as she looked intensely into my eyes. Cool gel was spread inside and out of my asshole and I felt het beging to insert her fingers inside of me. When three fingers were in, she began to slowly pump them in and out of my ass. I felt a fourth finger inserted and the process was repeated. I was being stretched more than I had ever experienced before and I was caught between pain and pleasure. She was stroking my cock as she pumped her hand in and out and I felt the come stir within my bound balls. "I think that this is enough for now, we will give it another go in a bit, but first let's remove the catheter." Dr. Kat took off the gloves and detached the ball harness. The blood rushed back into my scrotum and really hurt for a second to two. She then used a syringe to withdraw the water inside of the balloon in my bladder. Then she slowly began to draw the catheter out of my cock. It burned as she drew it out but soon I felt relief from the invasion that I had been experiencing. The mask was taken off of my head and a rush of fresh air enveloped me. I lay bound in the chair and for the first time in several hours was out of pain. Dr. Kat disposed of the catheter, gloves and syringe and came to my side. She took a moist cloth and wiped my face. Then she stroked my hair and in a low voice told me that I had done well. " I am afraid that you will suffer greatly; because I enjoy it and because that is what is important, but if you endure bravely, it will please me all the more." She drew her head to my ear and whispered more encouragement while blowing gently into it. As she did so, she began to play with my cock. It had been abused and still hurt, but was no match for her expert touch and was soon hard. " You see, you are a very bad boy and need you punishment. I will let you rest a bit and we will continue.," she mocked and turned to leave the room. She took out a blanket and covered me, then turned to go. As she did, she turned off the light. I lay in a relaxed state but my mind was buzzing. I had gone far beyond anything I had ever thought I could take and she promised more. I mulled over my condition for thirty minutes or so, but soon the excitement took its toll on me and I fell into a light sleep. How much time passed, I could only guess, but within an hour, I was bathed in light as Dr. Kat returned and flicked on the light. She came over and took the ball harness hanging from the rope and pulled it down toward my crotch. She expertly snapped it into place and the counter weights pulled my balls up and away from my ass. " We cannot have these drop down at a critical juncture, so let's add some more weights." She took a five pound lead ball an attached it to the three pounds already pulling on my balls. The eight pounds pulled hard against my balls and they began to ache. I saw her douse a cotton swab in cinnamon oil and felt it inserted into my asshole. The burning began immediately and I squirmed as she prepared herself. A long glove was put on her right hand and lubed up. Three fingers were inserted and pistoned in and out. Another finger was added and she pumped me for three or so minutes. " Now for the pain, Mike. I am going to put my whole hand inside of you." With her left hand she stroked my cock and I was soon rigid. Her hand had gel on it is it glided over my cock exciting a thousand nerves. I felt I might come soon, but the pulling on my balls made this near impossible. Her four fingers continued to pump into me and then I could feel her thumb slowly slip along side of the rest of her hand. Pumping this combined hand in and out she stretched me far past the point that I thought I could endure. I saw stars as she pain of it going into seemed to blow out the back of my head. Back and forth she moved within me until she had almost inserted the widest point of her hand. Out she withdrew it and once more pushed it inside. Ten times she almost got her whole hand inside and ten times she withdrew from the brink. Then on the eleventh time she grabbed my cock hard and pushed past my sphincter. Her hand was now inside of me and she stopped moving. I had almost passed out, but now was in a sort of delirium. I was so horny yet could do nothing about it. She began to move her hand inside of me and pressed hard against my prostate. Pre cum drooled out of my cock head. " I own you now. You are entirely mine and are totally helpless. Do you realize a woman has you completely at her mercy and that you are finally at the point where you should have been all along?" She began to slowly pump in and out again and I was more exposed than I had ever envisioned I could be. While the ball harness prevented an ejaculation, what I felt was something like a five minute orgasm. Finally she drew here hand out of me and left me to recuperate. "I am going to medicate you and put you to bed for the night. I feel that the best way is to give you another enema and include the medication within the mixture. The reason I stretched you so much was to be sure you could take the plug required to hold in the enema." She left the room and returned ten minutes later with a pitcher filled with a yellow liquid. She took an open topped enema bag, hung it from a IV stand and attached a butt plug nozzle. She lubed the nozzle and easily inserted it into my ass. The contents of the pitcher were poured into the bag and after pinching the air out of the tube, the clip was released and the liquid began to flow into me. " This is a liter of wine, my dear and will help you to sleep." After a minute I could taste the wine in my mouth as it penetrated my system. Soon the bag was empty and Dr. Kat quickly took out the plug after warning me about any spills. She took a large solid butt plug and lubed it up. I felt it press against my asshole and after a couple of in and out pumps, was shoved up inside of me. I grunted and it went in and thought how it would have been impossible to do so only a couple of hours ago. " I am going to put you to bed so I am going to detach you from all you bondage. Put these rubber panties on when I let you down from the chair. It will double-prevent any leaks." I was let out of the chair and after allowing me to regain any lost circulation, Dr. Kat watched as a pulled on the tight-fitting shorts. "Come over to the bed, dear, and we will give you a nice rest. I could use one as well," she said with a smile. I climbed on to the hospital bed and lay on my back when the doctor told me to do so. The plug in my ass pushed into me as I lay there but I soon adjusted to it. She pulled my legs apart and attached medical restraints around my ankles and then around my wrists. This were affixed with magnetic locks and I realized I was once more helpless. The doctor fluffed up a pillow behind my head and I lay there in relative comfort. "Even though we have those panties on, you will soon have to pee and I do not want you to make a mess, so I am putting on an external catheter." She lowered the rubber pants enough to expose the head of my penis and placed the catheter over the head of my cock. It looked a little like a condom but certainly could contain a whole lot more liquid. The wine was not taking effect and I was in a state of near total relaxation. "Good night and sleep well." She covered me with a blanket and turned off the light as she left. As I lay in the bed, I pondered the pain I had endured and realized that I as in a state of mental sexual arousal beyond anything I had ever felt. It was a good thing that the wine was giving me a strong buzz or I would get no sleep. I felt the piss fill my bladder and pushed to let a bit of it out. My savaged urethra burned a bit but the piss soon poured into the catheter and I could relax and fall asleep. Ideas were running around inside of my brain, but soon they turned to dreams. I fell into a deep sleep and stayed that way for five or six hours. I was awoken by a gentle voice and opened my eyes to the dim light inside of the room. As my eyes came into focus, I realized that the voice came from a young woman in a candy-striper dress. She was blond and very pretty. I saw her take the key and unlock the restraints on my hands and feet. "Hi I am Cindy, we need to prepare you for the days procedures, come with me to the bathroom." I was confused and a bit hung over. Who was she? I was embarrassed that I was naked in front of a girl half my age. Worse, my cock had a mind of is own and sprung to attention. " Go in there, remove the plug, take off and empty the catheter and go to the toilet. Then take a shower to clean up and knock on the door when you are done", she said as her eye caught my boner. I did as I was instructed and took a hot shower. Getting clean made me feel relaxed and I tried to prepare myself for what was to come. I toweled off and gently wrapped on the door. It opened and she stood there with a set of handcuffs. " I saw that you were as bad as my aunt said you were, so I have to make sure you behave yourself and that I can control the situation. Please put you hands behind your back." Her aunt? Well, I guess. I put my hands behind me and they were quickly secured. She went back into the bathroom and lay a large towel on the floor. "Come in and lie on your back,"she said trying to sound as authoritative as possible. I lay down and adjusted my hands so that they did not dig into my back. She put a blindfold over my eyes and I heard her leave the room. She returned shortly she put a gag into my mouth.and my head was lifted and placed into something that felt like a cradle. The blindfold was removed, and I saw that I was inside a box with a toilet seat over my face. My head was locked into place by a harness similar to that of guillotine. I could not move at all and the girl smiled as she looked down on me, and took a funnel and inserted it into the hole in my gag. "I realize that I have been up for hours drinking coffee and really have to pee. Let's see, there is a toilet over there and one right here. Which shall I use?" The taunting was causing me to harden and soon my flagpole was at full attention. "Well, would you look at that! I guess that this toilet will give me something to play with while I pee." She hiked up her skirt and straddling my prone body, lowered herself down on to the toilet seat. Her young pussy was only inches away from my face and my cock bobbed as I gazed on her. She leaned forward and grabbed a hold of it and began to stroke it. Just as I was about to spurt the cum that had been building up inside of me for a day, she stopped and giggled saying, " I really need to concentrate on peeing." She moaned and a second later a jet of piss shot out of her and into the funnel. I drank quickly and shut my eyes. She must have pissed out over tow pints of the golden elixer before she stopped. " To be honest, I drank a lot of water and juice before I got you up so that I could give you the full treatment. Now I believe that I should be rewarded for caring about you so much." She rose, took the funnel out of the gag and released me from the cradle. She wiped my face with a towel and took a fresh one and lay it across the cradle to cushion my neck. Then she gently pushed me back into position. Lowering the toilet seat and sitting down on it, I realized my face was now only an inch from her pussy and in easy striking distance. " Get to work you naughty boy!" My tongue lashed out and began to lick her delicious cunt. I felt her hand once more grab hold of my cock and stroke it. Her juices tasted sweet and I was really enjoying it. I heard a muffled moan and I stabbed my tongue across her clit. The moaning got louder and I knew she was about to cum. I too was throbbing and was going to join her, when I heard a a scream. Cindy jumped up off of my face and was screaming in terror. "Cindy,what the hell do you think that you are doing?" There stood Dr. Kat obviously angry. " Aunt Kat I have known about your domme lifestyle far over a year and last night I spied on you and this guy. I thought I would train him this morning before you got up and show you I am ready to join you in the life. I think I was doing a good job," said the candy striped niece. " You have a lot to learn and while you might have done well far, mistakes can be made if you are not taught properly. I want you to get out of those clothes and join me in the dungeon. As for you Mike, why did you not call out to me this morning? I never said we were going to do a multiple mistress session." I had no idea what she had had planned, but I saw little good could come out of pleading my case. I shrugged and struggled to my feet as my hands were still in the handcuffs. Kat undid my cuffs and told me to shower and then come out and join her and Cindy. I took a hot shower, toweled off and went out into the main room. When my eyes adjusted to the dim light, I saw Cindy strapped to a St Andrew's Cross. She was naked and looked scared. "Sit in this chair Mike." Kat said with a motion of her hand. The sturdy chair had a split seat and rings on the legs and arms to attach manacles. I was put into leather cuffs on my ankles and wrists and these in turn were locked into place to the chair. Kat took a parachute ball harness and attached it. From the ring hanging from it she hung five pounds of weights. She walked behind me and rolled a machine around to the side of the chair. Tubes were running out of the machine and to these she attached two clear cupping attachments. She flicked on the machine and a sucking sound came from it. The two cups were brought to my nipples and one was put over each. The suction from the tubes pulled my nipples out from my body and made them big and sensitive. The then took a third tube and attached a cock sheath. This was lubed up and put over my cock. As opposed to the attachments to my tits, this pulled and sucked rhythmically. The effect was not unlike a blow-job. With each pull, my cock expanded. " This will keep you busy for a while which will allow me to address my headstrong niece." She went over to a wall and took a flogger from a hook and walked over to Cindy. " As I said, if you are going to be a mistress, you need to know what you are doing to your slave. A good starting point is a whipping. I think that you will find this very educational." "Please Aunt Kat, I think I already know that a whipping hurts," pleaded Cindy. Paying no attention, Kat swung the flogger and brought it hard against Cindy's ass. A squeal was the result and a second blow found its mark. " Ow, Ow, Please no, Ow please." Smack!, "Please auntie!" Smack! The girl twisted and bounced as she shied away from the repeated blows. Tears began to flow and her pleadings became more plaintive. Her ass was aflame and glowed even in the dark room. It was more than seductive and my cock throbbed and the machine pumped away. Finally Kat stopped and Cindy collapsed and hung by her arms on the cross. I was moaning and thought for sure that I was going to cum when Kat reached over and flicked the switch off on the machine. My cock throbbed and I gasped out of frustration. "Now Cindy, I am going to let you down and I want you to clean up. Get into some hospital scrubs that I have in the closet and re-join us," said the Doctor in a clinical tone of voice. " As for you, you were enjoying looking at my niece's ass way too much! A little corrective therapy is in order for now." She took a candle out of a drawer and lit it. She then coated my cock and balls with a thin layer of gel and brought the candle to a point over my cock. The wax dripped off of it and I screamed in pain. " The gel will prevent the wax from sticking too much, as I want this area clean for our next phase." The drops of wax burned as it dripped over the head and shaft and down on to the balls and I jumped with each assault. I tried to not scream, but certain drops were too intense. My cock began to shrink under the assault and after ten minutes there was a clump of wax covering the entire area. Dr. Kat blew out the candle and started to detach me from the chair. I sat there as she went to check on Cindy. She returned and told me that the bathroom was free and I should shower and return when cleaned up. I took a quick shower, making special care to remove all the wax and toweled off. I returned to the room and found Dr. Kat and Cindy dressed in green scrubs and surgical masks. They were whispering to each other and stopped when I entered. " Please come over to the table and lie down," said Dr. Kat I climbed up on the table and Cindy secured my arms to the side of the table. Cradles were swung up from under the table and my knees were placed inside of them. Straps were pulled over and I was locked into place. Additional straps were pulled over my chest and I was locked into position. " Cindy, please roll over that IV and swab his arm for the injection." The young woman brought over the stand with a bottle containing a clear liquid hanging from a hook. She took a bottle of alcohol and doused a cotton ball with the alcohol She looked at my left arm and finally decided on a target spot for her assault. On my inside elbow she washed a vein and took a needle and attached it to the tube running out of the bottle. Then thumping the vein, she took aim and drove the needle into my arm. I could see a bit of blood back into the tube and then she released the clip on the tube and began the drip. " I thought we would calm you down by giving you a Valium drip," said Dr. Kat with an evil chuckle. " You could not be more helpless and that is too bad for you as the worst is yet to come. You would jump up and run if you knew our plans, oh and could run!" The drug began to take effect but at the same time, I realized my cock was being stroked and getting hard. "We need to lube your ass but I think some ice would make you a little more alive." I felt an ice suppository inserted and the chill shot through my body. " Once that melts, we will bring on the machine to do its work." Dr. Kat went over to a door and rolled in a machine that had a large dildo protruding from it. She put some lube on the phallus and positioned it between my open legs. She brought the head of the cock snug against my asshole and then attached chains to the base of the machine and the table so that it remained in position. She manually advanced the dildo and popped it inside of me. Adjusting the position of the machine and tightening the chains holding the table and machine in place, she flipped a switch and the machine whirred to life. The dildo began to pump in and out of me. I looked up and Cindy was smiling and reached down and tickled my balls. She then began to stroke my cock in time with the strokes of the fucking machine. " Oh Auntie, he is going to come soon and VERY hard." " No good for that to happen now, Nurse, better let him concentrate on the anal therapy. Take your hand away" Cindy slapped my cock and turned her back on the table. Dr Kat told her to come over and I saw the two conspiring. As I was reamed, the two of them prepared a side table. Lamps were brought over to shine on my groin and a new bottle was hung from the IV stand. Dr. Kat attached a needle and swabbed my scrotum with alcohol She cooed as she told me that this would hurt and inserted the needle into my sack. She released the drip and saline began to enter my ballsack. " Let's leave him for a bit, Cindy and have a cup off coffee to prepare us for the finale." My balls began to feel cold and my ass was sore from the pounding it was taking. I struggled but there was no relief. For fifteen minutes My balls filled with water. Finally the two returned and turned off the fuck-machine,detached it, and returned it to the closet. " Cindy, get the mask and put it on the patient. We have all the required items for the surgery and it is best to get started." A mask was pulled over my face and much of my vision was reduced. I was drawing my air through a hole in the front of the mask and it was clear to me that various devises could be screwed into the front of it. A clear plastic attachment was soon put into place and I knew that it would restrict the passage of air and require me to draw my air through that device. "Mike," said Dr. Kat, " I was really interested in all that you told me last night. Perhaps you do not remember all you said, but it is clear that you enjoy a loss of control. Well, that is you mistake, because you are quite helpless and I am sure that this is going to be much more than you ever thought possible. Cindy, show him the needles that are going into his penis." Cindy took several needles and brought them to the front of the mask. " You poor thing!, The small ones are going into your balls to drain it of all the water inside of them, but the large ones are going into your shaft. I cannot imagine how much this is going to hurt. I would never do this to you except my aunt has told me I am going to get a very severe whipping if I do not cooperate. Oh, and these medium sized needles are going through the head of you cock." The description of what was going to happen to me caused my cock to shrivel. Doctor Kat left the room for a moment and Cindy bent over me and whispered into my ear, " If you don't get hard we really cannot put in all these needles. Do your best to keep flaccid." Dr. Kat returned and eyeing my cock, said to Cindy, "Prepare his genitals for the surgery." Cindy gave a mocking sigh and began to tickle my balls. She ran her fingers up and down my shaft and blew into my ear. Pausing she looked at my cock and whispered into my ear to keep limp. Her tongue darted into my ear and her fingers continued to stroke my cock. "You are helpless to resist us, aren't you Mike?", Said the doctor. "You are helpless and totally in our control. You will yield to the pain and our power." My cock began to throb and soon I was rigid. A strap was secured around the base, trapping the blood within and my cock and balls were doused in alcohol It burned and I twisted on the table. A ball of cotton was filled with poppers and put inside the breathing mask. I began to feel the effect when the doctor brought a needle to the front of my mask to show me and then moved to my groin. A second later I felt it jammed into my scrotum. "Cindy, keep that size coming fast and furious as I want to insert them quickly before the anesthetic has a chance to fully take hold." In the next minute twenty needles were inserted into my balls and I bucked against the pain to no effect. "Now for your shaft," said the Domme with her eyes flashing. Searing pain hit me as the first of the huge needles was inserted into the base of the underside of my cock. I sucked in air and the pain was mixed with the drugs effects. Another was driven home and as the evil doctor brought her hands up into the light, I could see the blood on her gloves. Eight more of that sized needles were driven into my shaft's underside. Each time I gasped as it was far worse than Anything I had envisioned. " You look beautiful, my dear, so wonderfully decorated, but we need to put the crowning glory on top. Nurse, please give me two sized-down needles, we have our most fun work yet to come." Cindy pulled several paper-wrapped needles out of the drawer and removed the paper covers. The doctor took the first one and popped off the plastic covering. She brought it to my face and gave me a good look. " This is going into you cock-head. It will hurt so much!" She said with a mocking aire of concern. My shaft was pinched and the needle tip was brought to the underside of the crown. A second later, searing pain shot through me as it was pushed up through the head and emerged on the upper side. I screamed into the mask, but it only elicited a smile from the two women and I saw the second needle prepared. A moment later, the pain shot through me again and I was screaming incoherently. Sweat was pouring out of me and I was seeing flashes of light. This I felt meant that I might soon pass out. Two more times I was impaled and to say I was on the edge of madness, would not be overstating things too much. Finally it was over. The two women stepped back and surveyed their handiwork. After several mocking exchanges, they took the mask off of my head and I was able to breath sweet air. I was also abe to look upon my poor penis. Blood was oozing from the numerous needles. "Let's take out the needles and let our patient rest a bit." In quick succession, they were pulled from the cock and while painful it paled by comparison to their insertion. Once they were all pulled our, I was washed in alcohol and Ice was run over the cock to stem the bleeding. This went on for several minutes and I was cleaned up once more and my cock was wrapped in a gauze bandage. I was unstrapped and helped to the bed, where I was secured. "Cindy will keep an eye on you. You will need a little rest and I will go do the same." The lights were lowered and Dr. Kat left the room. As my eyes adjusted to the light, I could read the clock. It was just after 10:30 in the morning. Cindy was sitting in a chair next to the bed and I closed my eyes and dozed off. When I awoke, it was just past noon and Cindy was moving about the room. She noticed I was awake and came over to the bed to sit down. "So how are you feeling?", she smiled. "OK I guess." "Well we need to see how you recovered; so let's take a look." She pulled back the cover and slowly unwrapped the gauze bandage on my cock. I could see where the needles had punctured me, but there was no longer any bleeding and it was not in pain. Cindy reached behind her to a bowl on a small table and took a piece of ice in her hand. She then began to rub it up and down the shaft of my cock. With another piece of ice she rubbed my balls. I was getting wet from the melting ice, but also hard. Soon my cock was bobbing and after setting aside the ice, she began to stroke it. As I felt the juices begin to rise in my balls, she stopped. I hiked up her skirt and I saw she was wearing nothing underneath. Her hand parted her pussy lips and she began to slowly masturbate. "Mike, the reason I joined in to your torture is because I get so hot even thinking about making a man suffer. Now you're still helpless and my clit is on fire. I need to cum and I think it only fair that you have pleasure as I do; but not too much!," she said with a wicked smile. As she slowly stroked my cock with one hand, she frigged herself with the other. Her fingers alternated between fast and slow on both of us. I ached and wanted to get off, but any time I was about to, her hand would release my cock and it would dance in the air. After five or so minutes, her fingers went to a rapid rate on herself and her eyes rolled up in her head and he violently came. She squealed and she dropped back in her chair and left me there unsatisfied. "We can do this again and again. Does that sound fun, Mike?" "Yea, fun," I said sarcastically. "Well good then, let's start again." Her fingers slowly began to rub her pussy and she lowered herhead and concentrated on the feelings created. She licked the palm of her hand and applied to to my turgid cock. The slippery hand moved up and down and I tried to rock my hips to increase the pressure. Her touch was too soft, however to create the friction needed to cum. While I suffered in place, she moaned as the minstations of her fingers brought her closer to a climax. A minute or so later, she shook and thrashed her head from side to side. A squeal emitted from her lips and she sunk down in the chair spent from her orgasm. She squeezed my cock very hard then let go, leaving it bobbing in the air. "Is the patient ready for the final procedure?" Dr. Kat said as she stuck her head into the room. "Yes Auntie, I have him all jizzed up,"Said Cindy with an evil smile. "Then prepare him." My hands were strapped above my head and bars with cradles were brought from the side of the bed and my legs were strapped in. The bottom of the bed fell away and my ass was just hanging over the ledge. Dr. Kat came into the room wheeling a IV stand with what appeared to be a huge enema bag with over 4 liters of liquid inside the bulging bag. She wheeled it to the side of the bed and attached a double Bardex. I was greased up and both of the inflatable balloons were pushed inside of me. With and sly grin, she began to pump up the first, then the second balloon inside of me. It was still comfortable but I feared, rightly, that she would give it more air soon. "Since he seems so horny, we might as well get him to the edge," said the doctor. Cindy applied a little lube and slowly began to run her hand up and down my stiff shaft. I could feel the blood rush once more into it and the head began to turn purple. Pre-cum began to dribble out of it and I tried to thrust to climax. Cindy was too clever for that and pulled her hand away. I groaned and relaxed on the table. "Mike," said Kat," We will now combine the extremes of pain and pleasure. She walked across the room, opened a drawer and pulled out eight clamps. Walking back toward me, she set them down on a stand by the bed and turned her attention to the enema. She released the clamp and water began to slowly go into me. She kept the rate slow so that I did not feel any pressure for over a minute. Cindy was running her hand along my cock once again, and I felt intense pleasure. After a bit I could feel the pressure build inside as over a liter was now inside of me. Dr. Kat took the first clamp and squeezing the skin of my scrotum attached it. The pinching was sharp and it caused an aching feeling after twenty seconds. By then another was attached and she kept it up at that ps until all eight were hanging from my balls. Both women were seated by the bed and I could see that each had a hand under their skirt. They were frigging themselves as my pain increased. By the time all the clamps were on, I had almost three liters in me with one more to go. The pressure was massive and Dr Kat told Cindy to put a gas mask on me. Removing her hand from my cock and her pussy, she slipped the mask over my head and once in place, took a cotton ball soaked in poppers and put it into the air intake of the mask. The effect was almost immediate, but was somewhat counteracted by Dr. Kat giving three or four good pumps to each of the balloons in my rectum. The pressure of the water and balloons was so intense that I was not sure how I was going to get through this. Cindy went back to the stroking of my cock and frigging herself. Dr. Kat brought her face to mine and whispered, " I want you to have the most explosive orgasm that you have ever had. If possible I want you to come as we both do." Slowly Cindy's hand ran up and down my cock and I knew that I would cum soon if she would let me. "Auntie, I am going to cum soon, do you want me to bring him off?" "Hold on for a minute as I catch up, dear." Dr. Kat half closed her eyes and looked straight into mine. I hurt in my belly, but my cock was pulsing and on the verge. Dr. Kat began to have small spasms and I knew she would cum soon. "Let him go nurse." Cindy's hand pulled away and I thought I would go mad. " No, no, Cindy, I meant let him cum." She put her hand on my cock and gave it a hard squeeze. Then ran her hand up and down the shaft. As she did so, she squealed as she began to cum. Dr. Kat was in the throws of her own orgasm and I could feel myself move beyond the point of no return. I twisted in my bondage but Cindy kept up a slow and steady pace. The first of the spurts shot a foot into the air and was followed by several more almost as explosive. Both women had sweat dripping down their foreheads and were still cumming themselves. Despite her violent orgasm, Cindy kept up a steady pumping motion past the point where I stopped spurting. The intense pain/ pleasure of my orgasm left me drained; in all ways. After giving me a minute to recover, in which the clamps were taken off; I was released to get rid of my enema. We all sat around and debriefed about the session and I knew that I had found everything that I had ever wanted in a Domme. That, and her beautiful niece.
