I woke up with the dawn and felt not at all bad for having been through Heaven and Hell all the day before. I'd just been too damn tired and hungry to want to go to a hospital to get the little ball pulled out of my belly. I'd figured on getting that taken care of today and then going to the police about the dungeon. I got up and drew on the robe and searched around for a clean pair of panties and then got them on, too. The bra could wait. I went to the bathroom and then brushed my teeth before heading to the kitchen to get some coffee going. The fog had come in overnight but there were still a few surfers out riding what little wave action was to be found and I watched them as I waited for the coffee to brew up. It took forever for the pot to fill up and then I eagerly filled a mug with the coffee and a shot of cream. I took my coffee with me to the library and got the desk terminal to come on for the house computer. I went to browse through the files for the Perimeter Guardian and came up with a password prompt. I typed in "Waldo" and hit 'enter'. The sudden pain in my belly was awful, quick, and over as fast as it had started. If I hadn't been before, I was certain now that the ball would have to go. The password prompt was still there and I typed in "Pavlov" this time to see what would happen. I hit 'enter' and then I hit the floor, blinded with a gut-wrenching pain. I struggled to my feet again to look at the screen. A new mesage was displayed. "Pavlov32 is active. Obey programmed instructions or enter valid password to access and disable Pavlov32. Negative stimulation will be applied for attempts to violate system security." The computer was running the ball inside me? How? It was just a little ball. And how could the damn thing do all of this shit? I browsed to the index and found "About Pavlov32" and entered the file. I breathed a sigh of relief when it wasn't password protected. I read for at least an hour about all of the crap involved and finally figured the whole thing out. Pavlov32 is a behavior modification protocol designed to work in conjunction with a nano-computer encased in a frequency reactive platinum (not stainless steel like I'd thought) casing. The nano-computer uses the platinum casing as an electrode to receive and then transmit mild to severe pain impulses along sensitive nerve paths. The best placement for the device is near the spine and in proximity to sexual organs. In the female it is intended to be placed in the uterine lining via the vagina and cervix. From there it could provide five degrees of negative (pain) stimulation ranging from discomfort to agony, and five degrees of positive (sexual) stimulation ranging from mild arousal to an uncontrolled lust with attendant orgasms of varying intensities. All of the physical reaction information the computer needed on a subject was compiled from the workstations. When a subject, me in this case, was secured the system monitored the subject as series of pain and pleasure inputs were made, thus the system knew precisely what buttons to push to make me scream or moan. Ultrasonic sound waves are used to supply the ball with energy and the whole house must've been wired with the sound emitters. I say 'emitters' as I never saw any speakers around the house. The only way for me to escape the influence of the ball was to simply get away from the house. I left the computer and headed upstairs to get dressed. It felt nice to be clothed again and I grabbed my stuff and made for the door. I reached for the door handle, touched it, and BLAM! The damn thing felt like it was stabbing me. I tried again and the pain knocked me to the floor. Stupid me, I just HAD to try getting out the door one more time and I howled in agony as my hand touched the door again. This wasn't going to work, now was it? I left my stuff at the door figuring that if I shut off the computer then I'd be able to leave this damned place. I went back to the library and found the following message: "Perimeter Guardian activated. Behavior modification will commence in 193 seconds unless PASSWORD is entered." What the hell. I typed in 'PASSWORD' and hit enter. The pain was to be expected and I nearly blacked out from it. A new message was flashing on the screen: "Behavior modification protocol commences in 180 seconds. Subject must disrobe and mount INVADER." Fuck this, I thought, I'm getting out of here. I ran to the windows and hit the panel to open them and saw the display: "Behavior modification protocol commences in 162 seconds. Subject must disrobe and mount INVADER." I ran upstairs to see if I could escape through an attic and found no attic access in the whole upstairs. Running back to my bedroom I saw the display: "Behavior modification protocol commences in 41 seconds. Subject must disrobe and mount INVADER." The place was a fortress, I remembered. Hadn't Waldo shown me how there was no way into this house? There was no way out, either. I sat down by the bed and for the first time in my ordeal I cried. I can't say if it was tears of powerlessness or tears of frustration, but all I could do was hug myself and cry. Sitting there lost in my grief I wasn't surprised at all when the time elapsed and a slight cramping sensation began to build in my belly. A sharp pain went through me and I screamed at the walls. Then it went back to the increasing cramping sensation. There was no way out. The cramping made it difficult, but I got to my feet and walked downstairs to the dungeon. The last few steps to the dungeon were so painful I almost don't remember walking and holding myself up along the wall. The pain let up to a severe discomfort when I entered the dungeon, as if the program was cutting me a little slack for trying. I had to look at the display to see if there was any hope. "Subject must disrobe and mount INVADER." As if to remind me to get moving a sharp pain went through me. I kicked off my sneakers and undid my jeans, pushing the jeans over my hips and then down past my knees. As I stepped out of each leg of the jeans I peeled off my white cotton socks with them. Then my t-shirt came off right after another sharp pain reminded me to hurry. Another pain zapped me and I unclipped my bra and let it slip to the pile of my clothes on the tiles. I hesitated as the last thing to come off was my cotton panties, modest white briefs of course. My mind raced through all the possibilities and then a jackhammer of pain blasted through me, crumpling me to the floor unconscious. I came to with the ongoing presence of pain and found that I'd luckily collapsed onto my clothes, probably saving me from some serious bruising and maybe even some lost teeth. A zap of pain encouraged me to stop taking inventory of my condition and I got to my feet. Slipping my panties off, I sat back on Invader and was immediately met with the relief of the pain completely ending. I sat there and caught my breath for a few minutes and then felt a tang of a cramp as the program became impatient. Sitting back in the workstation my pain ended and as I placed my legs in the stirrups a pleasant glow swept over me and I allowed myself to relax. The manacles, collar, and waist restraint moved into place and I didn't care. The pain was over. After the constant and sometimes hideous pain the pleasant glow was a comforting and welcomed relief and I had no problem surrendering myself to whatever Invader had planned for me. It was wonderful to just lay back in the chair and I realized that having my legs bent and spread by the padded restraints was actually quite comfortable. I heard the cabinet in the floor open up and looked down to see the black tampon thing swing up. The warm lubricant was sprayed on my pussy and then it moved up and slipped precisely into me. I noticed the lubricant being a little warmer than last time and I found myself simply enjoying the sensation as it slipped all the way into me, filling me up as it went. I was just a little disappointed when it withdrew and then was replaced by the robotic arm with the phallus on it. I heard it start vibrating as it hovered just within touch of my body. I knew that this would be another incredible experience and I was ashamed to feel myself flush with arousal in anticipation of being penetrated by what was really just a fancy dildo. I'd never felt this way about my ex. I'd never felt this way in my life, come to think of it, and here I was excited about being impaled by a senseless machine. My arousal rose into a frustrating need. I watched the phallus and imagined it moving into me and each time I thought it was moving it just stayed still, the vibration audibly teasing me. The manacle on my right wrist came undone and I tentatively removed my wrist from it, expecting pain. Nothing happened and I reached down and found myself touching my body (down there!) in a way I'd never done in my entire life. That was when the pain hit. I yanked my hand back and placed it in the manacle, expecting it to close, but nothing happened. I was fearful that I was just going to be senselessly tortured when I heard a noise above my head and an arm with a touch panel on it came down and faced me. It was displaying a tic-tac-toe game and the message: "Complete the following task." A circle appeared in the upper left portion of the game field. The computer was playing games with me? Okay, I thought, this is easy. I reached up and touched the center of the game field and an "X" appeared. Shortly thereafter, I won the game and felt the familiar glow of arousal slip over me. The glow faded and then a new game field appeared. Again, I won and, again, I was rewarded with pleasure. The tic-tac-toe field was replaced with a game of checkers and over the course of maybe two hours I played several games with the computer, winning some of them, while the computer won most of them. With each game I lost I'd receive a slight discomfort, but with each game I won the glow would rise up in me. It was pretty clear to me that it was more pleasant to win than to lose. After I won the last game of checkers the glow of pleasure amped up to almost make me come. I was catching my breath with the oncoming joy and then it suddenly ended...kind of reminding me of sex with my ex! When I looked at the screen the gamefield had been replaced with a question: "A young, attractive man tells you that he is your Master. He instructs you to disrobe and assume a certain position so that he may mate with you. Do you comply? Select your answer." There were two circles, one with the word YES in it and one with NO in it. I selected NO. The zap of pain was pretty impressive and I screamed. Even though the pain only lasted a second or so, it was agonizing. A new question was displayed: "An older, unattractive man tells you that he is your Master. He instructs you to disrobe and assume a certain position so that he may mate with you. Do you comply? Select your answer." I knew it wanted me to agree and I just couldn't. I wasn't going to be anybody's whore, even if it was just a meaningless question from a computer. I touched the circle with NO in it. I broke out in a sweat and felt every muscle in my body seize up with the intense, electrifying agony. My lungs seized up and I couldn't breathe or even scream. I began to suffocate and I wondered if I was going to die. Just as I was about to black out, the pain and the seizures ended and I shrieked with relief and panted to get air into my starving lungs. My body was slick with sweat and I felt it pooling on the chair under my back. Looking at the screen, I saw another question: "An older, unattractive man tells you that he is your Master. He instructs you to disrobe, assume a certain position so that he may mate with you, and then he informs you he intends to make you pregnant. Do you comply? Select your answer." Pride and self-esteem demanded that I select NO. Fear and self-preservation dictated I answer YES. My finger hovered over the NO until it began to shake. The thought of being tortured again if I gave the wrong answer was more than enough to finally make me hit the YES with enough force to make the arm holding the panel swing away from me. Nonplussed, the arm simply returned to its previous position. I guess a part of me was still expecting to be zapped with pain even though I'd gone along with the answer the computer seemed to want from me. I felt my pussy lips part and looked down to see the phallus slipping into me. The wonderful vibration wasn't on this time and I guess I felt a little disappointed by that. The phallus settled into a very gentle yet steady rhythm of mindlessly thrusting in and out of my body. Even without the vibration it wasn't too bad. Instead of a raging orgasmic experience, it was just like a gentle, early morning fuck. No, it wasn't bad at all. A flashing on the screen in front of me directed my glance away from the gently fucking phallus between my legs. "Your Master is making love to you. He asks you if you like having him make love to you. Select your answer." Why fight it? I chose YES. The phallus gave me a deep, hard thrust, and then returned to its rhythm. It was a little uncomfortable as it went so deep into me, but it was somehow arousing as it responded to my approving answer. A new question came up: "Your Master asks your permission to fuck you until he comes in you. You are ovulating and know you might become pregnant if you agree. Do you agree? Select your answer." The gentle fucking of the phallus in my pussy had quickly become hypnotic. I really didn't care right then about hypothetical questions about what I might or might not do. I did know I didn't want any more pain and I also knew that I was seriously enjoying the wonderful fuck I was experiencing. I selected YES. The rhythm of the phallus began to gently pick up speed and it also began to drive deeper with each thrust. I could swear I felt it swell inside me...just like the real thing. In the middle of all of this another question came up: "Your Master is fucking you. You are completely unprotected and pregnancy is a certainty if he comes in you. Your body will swell with his baby and he will make you return to Invader to give birth. Your Master tells you that he will stop if you ask him to. There will be no penalty if you refuse him. He will let you walk free from this house. He asks you if you will let him come in your womb, let him inseminate you with his seed, filling you with his baby and making you his slave for the rest of your life. If you agree you will never leave this house without his permission. Do you agree to be his slave for the rest of your life? Select your answer." I wasn't really thinking too clearly just then. A glow was building in my belly and I knew I'd be feeling fabulous if I let this thing finish its job. I briefly considered the expected negative of a shock of pain if I disagreed with the question and knew I didn't need anymore pain today. And what the hell, it was just a stupid computer question, right? I selected YES. The phallus began a series of lingering, deep thrusts into my pussy. With each thrust the phallus would writhe and twist, straining itself at my pussy as it tried to get deeper. At the same time I felt it begin to buzz and vibrate with my special frequency. It was sheer, absolute Heaven! This thing wasn't just fucking my pussy, it was fucking my soul! It couldn't have gotten any better when I felt the glow inside me rise up like a tidal wave of pleasure, building and building me up to higher and higher levels of sexual pleasure. The ball inside me was unleashing the full promise of pleasure in my body and I was ready and primed for anything it wanted to do to me. Just like an impassioned lover, the phallus changed from fucking me with deep thrusts to a hard, rapid pumping of my pussy. I heard the obscene sound of it slipping in and out of my pussy, the wet smacking sound echoing in the dungeon. I scooted down to get it deeper into me. It responded and fucked me faster and harder. This time I knew it wasn't just my imagination as I felt it swell inside me. And that did it for me. The Gates of Heaven opened up and I was ushered inside by angels as the most concerted pleasure crashed over me. My pussy contracted with waves of pleasure, sucking the thrusting phallus deep into my welcoming womb. The ball inside me evoked and even deeper and more pervasive pleasure as my body now demanded to be filled. The thrusting cock...it was my lover now and no longer a machine...it hammered me deep and hard and even painfully as it crashed itself into the door of my womb. And then it got even better! In the midst of the absolute most intense joy I'd ever felt the cock held itself deep inside me, impaling me on its length. I felt it swell more than before and then it began to ripple in waves. I felt a hot, liquid presence in my pussy and knew, just knew the cock was coming in me! The hot, spurting liquid seemed to fill me with an awesome, blinding pleasure. My every sense intensified and I swear I could see in my minds' eye the wonderful tip of the cock spurting its cream into my ready, willing womb. The feeling of the hot come spurting into me didn't stop for an eternity and my wild, intense orgasm contiued on in waves of heat and light even after the cock stopped thrusting and spurting into me. The cock finally pulled from my body and I was acutely aware of feeling thoroughly and completely feminine. My breasts felt wonderful. My belly was satisfied with the lingering warmth of both the spurting come and my sexual supernova. The restraints were already opened but I was in no hurry to get up and leave. I felt myself smile with a stupid, satisfied grin as I lay there, my legs splayed open and my pussy dripping with...what? I reached down to my soaking pussy and ran my hand over it, gathering my lust and the product of the cock into it. I lifted it to my eyes and then I sniffed at it. The somehow pleasing odour of my own musky scent was present and then I caught the perfume of the slick fluid that had been sexily and hotly pumped into me, I wasn't sure what it was. The scent was kind of flowery, but there was also a medicinal quality to it as well. A little part of my glow faded when I couldn't figure out what had been spurted into my body, yet I still was in more joy from the afterglow of my fucking than I'd ever been from any male-induced orgasm. The computer screen displayed a new question: "Did you like it? Do you like being a slave?" I was free to go. I didn't have to answer. Yet I did. I reached up and touched YES. I'd never been happier in all of my life. Laying there in the afterglow I contemplated having experienced Heaven and I abandoned myself to a warm, restful sleep.
