In part it was a hangover from my meeting in the Headmistress's office and the multiple orgasms had on the floor of the teachers bathroom. The plug in my ass was now becoming a cause for pleasure in its own right. Every step I took shifted the intruder and brought up desires that a day ago would have caused me to shiver in disgust. My class was standing in two lines awaiting the start of the lesson. I added myself to the group and saw Jenny in the front row. She turned and gave me a surprised look. I winked and she turned back and faced the gym floor. A voice echoed across the room, "For the remainder of the afternoon we will be practicing what you have learnt over the last week." The teacher's voice moved around the group until I caught sight of her in my left eye. She was older than all the other teachers with streaks of great through her ebony hair. My guess was late forties but with her toned physique and magnificent breasts she was still stunning. A whistle connected to a red lanyard hung around her neck and in between her breasts. Though not the largest I had see that day they were firm and round. Based on her figure they had to be fake. Not an ounce of fat was to be seen, but at the same time she still appeared elegant and feminine. "Front row, roll out the mats" she paused, "Go!". On that word the front row, a mix of boys and girls ran over to the far corner of the gym and began rolling out a series of long vinyl covered foam mats. "Rear row, ten star jumps, Go!". As we started jumping I looked down the row at the boy next to me. He was slightly taller and although my age had the beginnings of a mans physique with nice pecs and flat abs. The other part of him that caught my attention was his cock. Locked in a plastic cage with only his balls exposed to the air it was bouncing up and down. This bouncing was clearly having an effect. His cock swelled inside the device and the tip tried to force its way out of a narrow slit in the front. This pressure dragged the rest of the device forward pulling his sack through the retaining collar. His sack went tight as his balls were squeezed against the hard plastic. The discomfort was evident on his face but his cock strained for release none the less. He looked at me and I looked at him. I smiled, looked down at his crotch and then licked my upper lip as we finished our jumps. Before I could speak the teacher called out again, "Two rows on the far side of the mats, Go!" We ran over and I lined up behind the boy with the straining cock. His ass was toned and his shoulders had the form of a swimmer or a rower. While the rest of the class formed up I caught myself thinking about the object to my front. I didn't know his name but I knew enough. He has handsome, fit and randy as hell. He looked over his shoulder and caught a glance of my ravenous eyes. He spread his feet ever so slightly and pointed his feet slightly closer to straight. All this had the effect of tightening his butt and exposing the a portion of the base of his school plug. "Jenny" the teacher called out, "what did we learn this week in class?". Having only started class today I was thankful that she asked my room mate not me. "Measurement of human physical performance Ms Smith" Jenny called out. "Good, lets see if you can do better. Name a method of comparing human aerobic performance across a group." Jenny paused and thought, "We could measure how long people can hold their breath?" She was less confident than before and her words hung in the air. "Good answer" replied Ms Smith. "Today class, we will conduct a comparative test, Who would like to be part of the demonstration?" The class was silent and no one made a move. Despite the sexual antics it seemed that none were keen to volunteer. Having lost my sense of shame at the bladders of her colleagues I caught Ms Smiths attention by raising my right hand. "I would ma'am" I called out. "Ah, the new Jenny that I've been hearing about," she quipped. "I'm sad to say that I was busy over lunch and was unable to," she pondered with a wry grin "shall we say, spray my piss into your thirsty slut mouth." Jenny's eyes darted to mine with a look of shock. I too was surprised with my new teacher. Not because of the revelation that I had been transformed to a piss slut, but the phrasing of her quip. It was almost like she expected me to be frightened of hearing the events of the lunch break recounted in public. My competitive streak came running to the fore, "I'd love to drink your sweet nectar anytime Ma'am." In part it was sarcasm aimed at showing I was no pushover, but I wanted it. The opportunity to go further, but not just for myself, but to be seen by others seeking it out. To be looked at as the girl who would do anything anywhere with anyone or anything. My heart quickened as I digested the effect of my words. "Out front on your knees, Go!." There was no need for Ms Smith to say my name, every one who could hear knew who she was talking to. I pushed past the boy to my front and stood in front of Ms Smith. Through the corner of my eye I could see a look of amazement on Jenny's face. I placed my hands behind my back and with each hand held the other elbow. I slowly knelt on the mat, my mouth open looking up into Ms Smith’s eyes. She stepped forward and took her whistle off her neck. She placed the lanyard around my neck and placed her cunt into my face. I felt the lanyard pull my head forward as she dragged it between her legs. My face was mashed into her mound as she began her stream. She hadn't been to the toilet in quite a while. A salty spray gushed into my waiting mouth. I sealed my lips against her pussy and began swallowing as fast as I could. A single droop of wasted fluid would be seen as failure after my brash statement. I gulped and choked as some of the torrent sprayed up the back of my nose passage. I felt her flood stop as the piss that had entered my nose from my throat ran down my cheek. The lanyard around my neck fell slack and I quickly tilted my head to the side. Keeping my hands locked to my rear, I guided the precious drops towards my waiting tongue. Once close enough I lapped it up, looked up at Ms Smith and again opened my mouth ready for more. I could see her clit throbbing out of its hood and her nipples bursting from her chest. The cord around my neck went tight again, this time though as my lips locked on to her mound she reached down and held my nose shut. I waited, ready for more of her salty nectar, but none was forthcoming. She tilted her hips forward and I understood what was required. My tongue darted forth and lapped at her cunt as my top lip hummed against her clit. My heart began to race as my lungs burned for release. I knew that Ms Smiths orgasm was the key. She began to quiver as the pleasure rose in her belly. I probed deeper and deeper, all the while keeping my hands firmly at my back. She convulsed as her orgasm reached its peak. I was sure that my face embedded in her crotch was the only thing preventing her collapse as she released my nose and steadied herself with an hand on my on my head. The lanyard went slack again as she guided my face from her now dripping minge. "Well done," she said "lets carry on with the demonstration shall we. Lie on your back with your legs facing the rest of the class." I did as commanded and awaited further instructions as she removed a fluorescent plug from her ass. "To ensure we get an accurate result of how long you can hold your breath we need to ensure a tight seal" Ms Smith stepped over me and lowered herself onto my face sliding her slightly gaping ass hole over my nose. Her now engorged pussy lips sealed across my mouth and the world went dark. I could hear her explaining what was a good time or a bad time, signs to look for and when the tester should get off the subjects face. "In particular you need to check some where that is getting lots of fresh blood for any discolouration" she explained as her fingers parted my pussy lips for all to see. "Pinch the skin and wait for it to regain its colour" she said as squeezed my clit. My heart raced as I felt my blood boil, Again she squeezed my clit, but this time she didn't let go instead she twisted and pulled my sensitive nub. The pleasure it caused was almost overwhelming but the pain prevented me from going over the edge. I slapped Ms Smith on the back and she realised me from her loins. As the seal around my lips broke I wasted no time in sucking in much needed air. Along with the cool relief I inhaled a mass of wet juices dripping from Ms Smiths snatch. I choked. coughed and jerked my head upwards driving my nose further into her back hole. This caused a chuckle of laughter from my class and my teacher. She leant forward and stood up. "That was an excellent demonstration Susan", she remarked. "You've set a very competitive time of one minute and eight seconds. Now back to your spot." Still catching my breath I returned to my spot behind the boy. "Those in the back row will first test the person in front of them" Ms Smith announced. The stud to my front twisted his head slightly. Not enough to look behind himself, but enough to let me know he was pleased with the thought of my ass smothering his face. "Front row on the mats, Go" ordered my latest piss donor. The boy sprang forward and lay on his back looking straight up at my dripping puss. "Rear row move into position but don't sit down yet, Go" I stepped forward lingering over his head and squatted slowly to give him a good look, his cock strained in its cage. I held the squat just above his face and pondered out loud, "Ms Smith played with my clit to check that I was alright, what should I play with here…" I ran my hand down his smooth chest towards his throbbing cock which strained harder against its cage with every heart beat. I noticed his cock head becoming damp as my hand got closer. "It is in the best interests of those about to be tested to remove their testers plugs, do that now." Ms Smith said interrupting my torment of the boy between my legs. Without a word he reached up and began to gently pull on my plug. It had been in all day and with all my orgasms my sphincter had locked itself tight. Slowly but surely my partner began to loosen the metal object from my ass. My hole stretched more and more and my arousal built once again. My mind recalled the scenes of Melissa's ass being worked by her shower lover and Ms Jones. Finally it came free and a rush of cold air rushed to fill the gaping void that was my ass. I shivered, in part from the new sensation and in part from the final tug he gave. "Once the tester and subject are ready you may begin, and don't forget to count" ordered Ms Smith. Without waiting I dropped my self on the hapless boy's face smothering him mid gasp. His nose disappeared into my ass and my dripping lips went firm around his mouth. I gently began to stroke the hairless base of his confined erection whilst my other hand twisted his nipple. I could feel his heart racing as my finger found its way to the end of the cage. There I gently slid my fingernail into his piss slit that was being forced out of the cage. That was too much for the boy sucking on my juices. His hips bucked and his hands gripped my hips holding me hard against his face as his tongue flickered into my pussy. His nose too went deeper and went someway in replacing the plug now resting by my foot. As he quivered his orgasm came and with it a load of cum spurted from his cock over my hand and the gym matt. Ms Smith noticed the commotion it caused and closed the distance with purpose. "How dare you do that in my class, you're going straight to detention young man!" She exclaimed as she took off her whistle lanyard. I recoiled in fear as she swung the whistle towards us. The whistle struck the boy square on his straining balls. He curled up in agony as the the teach grasped him by the ear. I was shocked, not least of all because I was the one who cause his orgasm. As I lay with my legs still wide apart I gazed at Ms Smith as she dragged my boy away by the ear. "Class dismissed" she called out leaving us to our own devices. I looked around and saw Jenny moving to my side. "What a disgrace she said as she moved to hug me. I pushed her away unsure of all that surrounded me. "We're all going to pay for that one way or another" one boy remarked to another. I couldn't believe my ears. I turned to Jenny, "Whats going to happen to him? It was my fault, he couldn't help it" I asked and explained. Jenny gripped me and looked me in the eyes. "Don't blame yourself babe, he knows better than that" she said. "All the boys know that their not allowed to cum in class". Still in a state of disbelief I pressed Jenny to find out what what would happen next, "We'll all see soon" she replied. Everyone now started to re-plug their holes. Some required assistance, others were fine on their own. We gathered around awaiting the end of the period. Even I knew that the next class was detention. We moved as a group into the courtyard to find the boy locked in a set of stocks set up amongst what I had previously thought of as gymnastic equipment. I now realised that his was no sporting area, It was an open air dungeon. As the class rooms emptied a small crowd gathered around. "What are they going to do to him?" I asked Jenny. "You and Ms Smith are going to be plunder him with giant strapons" she replied matter of factly as she rubbed her hand along my cheek. I was aghast at the thought of hurting this class mate of mine but the thought of pillaging the boy's ass was beginning to arouse me. "What counts as a giant strapon" I asked. "Well it depends how old you are" Jenny explained. " You take your age, multiply by four and subtract fifteen. Thats how many dildo inches you get." She seemed quite serious and knowledgeable about the matter. "Now this is where the boy will get a choice. There are different lengths and widths available, all he has to do is pick one where the length multiplied by the length is greater than his dildo inches. I did the maths, he had to take 41 inched of synthetic cock. " That's huge I exclaimed" as I realised that even if the dildo was three inches across it would have to be over 13 inches long. "Its show time" Jenny remarked as Ms Smith walked up to the boy with a long bag and placed it to the side. She looked around, seeing me she waved me forward. As I emerged from the crowd Ms Smith handed me a strange device. It was two reasonable large dildo's with small grooves on the side connected to a curved bar of plastic. There was a stepped protrusion facing away from the dildos and a small knob beneath each. "Come on, I haven got all day" said Ms Smith as she removed her fluorescent plug and placed it on the grass. She slid the bar in between her legs and raised it, a dildo entering each of her holes. I now realised what this device was, some form of strapless dildo mount. I followed suit removing my own plug and sliding the plugs into my gaping ass and still tight pussy. I saw Ms Smith fiddle with the knobs between her legs for a moment before she reached for my own. "This will keep them in" she explained. As my teacher twisted the knobs each of the dildos expanded in my young holes. She continued to ratchet them open until the deice was firm locked against my young body. Ms Smith then handed me a bottle of lubricant and directed me to prepare his ass. Unsure of what to do I gently removed his plug and smeared some lube onto his waiting hole. "Like this" Ms Smith said as she grasped the bottle from my hands. She inserted the end into his anus and squeezed filling his rectum with slick jelly. Ms Smith then moved around to his face, squatted and asked him for his preferred size of dildo. " The one with the big bumps and the long red one please ma'am" he replied. Ms Smith retrieved the dildos from the bag and gave me the choice, A red one almost a foot and a half long over two inches across or one just over a foot long with a series of bulges that increased in size towards the base. The expandable dildos in my two holes were having an effect other than the security of my harness. I realised that he was going to get both dildos any way. If I took the thick one I could be gentle to him, I supposed as I reached forward and grasped the toy. But deep down I knew that it wouldn't be that way. I could feel the lust building as Ms Smith affixed her long toy to her harness and guided it deep into his colon. As Ms Smith slowly reached her full depth I saw and amazing sight. I could see the toy bulging in his belly. By the long line of cum seeping from his cock, this punishment appeared as effective as my own earlier in the day. He was writhing in pleasure as the rubber snaked its way through his insides, moaning each time The older woman thrust into his boy ass. She too was enjoying herself as the dildos moved around inside her. Her pace quickened and with deep thrusts she assaulted his shitter. She gasped and shivered as her loins convulsed sending shockwaves throughout her body. Ms Smith slipped the dildo from the young man's ass, turned to me and said “Your turn Susan." I stepped up with the head resting against his gaping hole. As I pushed forward the first of the bulges slipped into his ass with ease. Further still the second bulge met with some resistance. He moaned as I began to softly thrust into him. in a few moments the dildo was half in.The third bulge however was no such slouch. I reached forward and held his hips as mine pushed forward. with each thrust he moaned in pleasure as his sphincter was stretched wider and wider. My pussy was tingling and there was a fire building inside me. I began to move harder and faster assaulting his ass. The third knob popped through only to be dragged back out a half stroke later. In and out it went, our skin drenched with sweat. His caused by the pleasure he felt as the toy working in and out smacking on is prostate. My sweat was in part due to the pleasure in my own holes as the dildo's held on tight. The physical act too was causing me to pant as by hips flashed back and forth. I was loving this. The feeling of power over the young stud before me, the visible distress of his ass was almost more than I could take. There was only one thing else to do. The fourth bulge, unlike the others had no narrower back side, simply retaining its 3 inch girth right to the base. As my orgasm approached all thoughts of mercy dissolved. His ass was mine and I would make sure that he would never forget this ravaging. Again and again I thrust forward. Harder and harder. His hole continued to dilate with every thrust. A wave of pleasure washed over me and I lost all concern for his comfort or safety. I rammed the dildo in with all my strength gripping his tight hips as his ass succumbed to this final intrusion. He cried out and convulsed as my three inch diameter tool remained buried in his ass. I withdrew the toy from his now plundered hole as it gaped back at the crowd. A small round of applause erupted. I looked around and made a small bow of thanks. The crowd began to disperse and I saw Jenny approach as I removed the mount and returned it to Ms Smiths bag. "That was incredible" my rommie exclaimed as she hugged me close and kissed me. "How have you become such an animal? I heard about your punishment and you shocked everyone in the gym." I reassured her that I was still the same girl, but I was just caught up in the moment. I knew this was a lie, and I think she did too. As I looked back at the boy who's name I still didn't know his ass still gaped as a trophy to my new desires.
