Classroom Demonstration Wind swirled around the campus grounds. A few leaves crackled, their dry cores rubbing against the brick sidewalk. Greg shivered, having only worn his dress shirt outside. The cooler weather had come out of nowhere. His hands rubbed against his arms in order to try to warm them up. His backpack dug into his shoulders, the books leaning backwards. He'd gone this way to his classes before, but decided to take a turn through one of the outer buildings in order to keep himself out of the cold. Greg had never gone this way before, and felt the heat hit him with a wonderful sense of relief. A sigh escaped his throat before he began to cut through the building. To be honest he wasn't sure what this building was for. It hadn't been on the tour when he applied to the college. And he was sure that they hadn't mentioned it when they passed. Even the classrooms here appeared to have been abandoned long before. A few were even stuffed with extra desks. What was the strangest to him was the bulletin board; the fact that there even was one in this day and age was strange to him. Most school options were either emailed or put up on the school website. A physical bulletin board was somewhat anachronistic. Everything on the board was from almost a year ago, and it appeared that there were very few that even looked that interesting. He'd have probably missed them even if they had been posted online. Not that any of these were online. His eyes wandered all over the board, seeing the age that was obvious in the paper. Weather might not have worn itself on these sheets, but time certainly had. All that is except for a single sheet of paper near the bottom. It hadn't seen the time needed to age it into not being comprehensible. It appears that a Dr. Good, a silly name, had a human sexuality class that needed a student volunteer. He looked at the reward that it offered. There were only two tabs left. He checked to see if the payment was actually written on the paperwork. It was rather easy to see at the end of the slip. "$250 for one class." Greg smiled to himself. When you attended college what you always needed was a little extra money. Or sometimes a lot of extra money. Greg had seen the cost of books for this semester and was sure that any dent he could make on his debt would be helpful. The number was on the tab, his fingers playing on his cell phone to get it on. They did mention that he was supposed to call rather than text or email them. He could hear ringing on the other end. "Thank you for calling Dr. Good's office, how can I help you?" The voice sounded rather syrupy sweet when he heard it for the first time. "Yes, I was calling about the human sexuality class volunteer. Do you still need them?" He hoped that she was going to answer yes. If they were no longer needed, then he might be out of luck about those books. "Of course we always need new volunteers for our classes. Now before I get your information I must inform you that this will include some nudity." That made Greg pause for a moment. Though with human sexuality there probably was going to be a little nudity. "Does it still pay the $250?" he asked, that being the deciding factor if he was still interested. "Yes, the price hasn't changed." That made him nod, glad that they were sticking with that. "Then I am interested. What information do you need?" she asked him a few about his health, and even a few embarrassing ones about his penis size and other sexual preferences. That was something that he himself didn't think about. Or at least not in that clinical a way. The class was supposed to meet a few days from then. Greg suffered through having a small budget when he had to purchase his books. They were just as bad as he thought that they were going to be. The costs of books this day and age were milking him of his money. He wanted to be quintessential to her class, so Greg made sure to arrive early. The classroom door opened with a creak. This was a normal classroom, though one that he hadn't been in before. It spread out before him. His eyes looked over the empty desks, along with the strange door that appeared to be set next to the teacher's desk. Most classes had the back doors along with the emergency fire doors. Yet this one had an additional set. The door he'd been staring at suddenly opened. A rather lovely young woman arrived with a big smile on her face. Her body looked like it was formed to her clothes, her blue blouse opening to reveal just the proper amount of curves to her form. "Hello, I believe you are Greg correct?" she asked before extending her hand. He accepted the hand, shaking it in return. When she released she walked over to the board to list a few things that he could barely understand. She had left some of her things inside of the desk, pulling them out before she sat on her desk. "Well I suppose we need you to know what we are going to be doing today. I have a specific group of girls who have to take a special course due to their majors." She went on about a few specifics tht he didn't really care about to be completely honest. When she saw his disinterest she reached into her pocket to pull out an envelope. I know this is what you are really interested in." Her smile was rather unnerving to be honest. Almost like her canines were just a little too long. But, Greg didn't worry about that before she handed him the envelop. "Now the girls will be here shortly. There aren't many of them, and you will have to strip when I give you the proper orders." He had to hand back the envelope now after he'd made sure that they had the right amount of money. Very shortly he heard the door open, a flurry of talking from the girls themselves. The class was tiny with only four girls entering. She nodded to each one before they got to their seats right in front. His eyes scanned over each one. All of them looked prepared, and his eyes roamed over their bodies. Right now he was going to be showing them a lot, so he hoped that they would enjoy what they saw. He might be able to get a few numbers. At least he might have if she had introduced him to the class. Instead, she kept it purely business before she directed him to stand in front of them. "Hello class you remember our discussion last time about the male physical form. You have learned much about them, and I know you are ready to see a full specimen." The girls chuckled to themselves before they got out their notebooks. Their pens were ready to take any notes that she might give them. "Now you remember each basic part of the body from head to trunk to limbs." Her voice seemed to drone for a second the more he heard her. It was so seperated from any real warmth about him. Almost like he were a piece of meat that she were showing before she sold him. "Now please strip out of your pants and underwear," Dr. Good ordered him. Carefully he slid his pants down to reveal his penis. The order probably meant for him to simply pull them off, but he felt a little nervous with those intense gazes of the girls on his member when it limply pushed out of his pants. "Well that will not do," Dr. Good said before she reached into her case again. Greg followed her hands when she pulled out what appeared to be a golden halo. It was shaped rather oddly with a dozen blinking lights that were underneath the metal of the machine. Slowly she placed it over his head. With a turn of her fingers she turned it on with a little hum filling his ears. The entire room felt like they were leaning in to see what happened. Each individual girl looked like they were ready with extreme interest. What might be going on with this halo that she'd placed on his head? An electric rush filled his spine, making Greg take a deep breath. His eyes opened wide when he looked at each individual in the room. His eyes turned to look at the teacher, her smirk making him feel even less sure about this whole situation. In an instant his cock suddenly engorged. He went from a nervous flaccid penis to a fully erect, throbbing member. Greg gasped, his eyes looking down at the angry red member that thrust into the air. Each beat of his heart made it spasm against his belly. To be honest he didn't think he'd ever seen it so big before. The angry red color grew with the tip flaring outward. The teacher chuckled a little bit to see the head thrusting out, growing to a reddish color before his pee slit opened slightly to let a little droplet of pre-cum ooze from his tip. His breathing came in a long deep gasp that filled his chest. The entire experience was strange, yet he found that he wasn't able to say anything. His mouth didn't obey his orders to it. Dr. Good moved around the desk to place one of her hands gently on his hip before she wrapped her soft fingers around his engorged manhood. A jolt went up his spine with that movement, his breath catching in his throat. Greg couldn't believe how good it felt. The way that her fingers and palm gently massaged each inch of his skin. "Now you can see that the male penis grows erect to prepare for penetration. We don't want to get into female anatomy yet, so we can't let him have that. But, we will be sure that he does at least climax. We can't have him not show you a male orgasm after all." She said with another little smirk. All the girls were intent, their pens not moving as their eyes were glued to the two of them in front. Some fidgeted in their seats, moving with their hands covering their crotches. The angle was too low so that Greg couldn't quite see what they were covering. "Oh before I forget," she said, removing her hand from around his penis. She'd moved so that he couldn't see her and the movement of his eyes was limited since he couldn't move his head. Dr. Good pulled a condom packet from her pocket, moving to roll the clear thing over his engorged cock. The coolness felt like it would melt under how hot his body felt at that moment. Each roll made him feel a slight shudder that travelled down his groin. The condom didn't prevent him from feeling every inch of her hand against his hot member. It throbbed inside her smooth hand with every stroke. Soon she was massaging her palm around his covered tip every time that she reached the top before she went down to the base of his penis. Each time she passed she gave it a little squeeze with her fingers to get the most from her movement. There had never been any hand job like this before. Greg moaned deep in his throat involuntarily with every stroke before she was moving faster and faster. Pressure built at the base of his testicles, moving up around his stomach so that he could feel his entire groin area preparing to release. His control over his movement shouldn't have influenced his ability to not be premature. But, with a few more passes of her hand he felt himself cum. Greg's little pee slit opened to let out a thick gush of semen into the condom. The thick ropes of creamy white semen splattered into the reservoir tip. All of the movements of her hand didn't stop with her fingers still keeping up the rhythm. He gasped another breath as the orgasm didn't end. More warm white cum poured from him, his cock jerking within her massaging hand. There didn't seem to be any end with his body tensing with every orgasm. There were little white dots of light dancing in front of his eyes. He lost count of how many times he'd shot his load into the condom. From the feel of the weight he was shocked it hadn't burst yet. Greg jerked with every cum as he felt like he was giving birth to each burst of semen. There was no way for him to know that the strange orgasm lasted for 5 minutes, the eternity it felt was something that he would never forget. Now panting for air Dr. Good moved his body herself so that now his ass was resting on the desk. The wood felt rather cold to the touch, as if right underneath the wood was a cold metallic desk. That didn't make any sense to him, so he ignored any sense of trepidation he should have felt. Taking in deep breathes she moved his head downward so he could see his groin. A little tuft of hair chaotically formed above his penis. It took a few seconds for the light dancing in front of his eyes to finally dissipate so that he could see what she wanted him to see. In front of him the condom leaned forward with a large volume of semen. The condom spout had kept a volume of cum that could have easily filled a baseball. It was a slight off-white with some strange dimensions to it. Every single one of the girls was now closer so that he could see all of their curious eyes at the little bubble of cum. Dr. Good removed the condom with a wet sound that filled the air with the scent of his sperm. It made Greg's nose itch, and the teacher tied off the condom so that she could dispose of it in the trash can. The room was filled with heavy breathing. Each girl seemed to be trying to keep themselves under control with the situation that they'd seen. Greg felt a little beam of pride that he could get them so hot and bothered. The girls around him clapped for her before she began to talk again. "You saw the male's semen has been totally expelled from his body. The machine on his head has completely emptied his scrotum of any sperm." He made his eyes look down, which thankfully his head was now aimed at. Could you completely empty a man's balls so that he didn't have a drop left? "This includes his testicles. Every single drop and the organs themselves have disappeared." Now he could easily see her lifting the empty scrotum to the girls in front of him. There should have been bulges to reveal where his balls were. He should have seen one of his testicles roll out of her fingers with the way that she was holding it. Instead, there was only a loose flap of skin that when she dropped it hugged his body. His loose scrotum held nothing inside. Any cold draft would have made it tighten against an empty sac. "The machine is designed for this, and you will all have to remember to use it properly." His erection faded quickly, his cock going from raging hardness to completely flaccid in only a few seconds before it laid on the empty scrotum. "I know some of you just want to ambush a boy, but remember to do it calmly. Best to get them in a relaxed state, it makes it easier." He tried to move even harder, but she was easily able to just slide him right onto the desk before the other girls crowded around to watch. Now Greg was slightly leaning with his back against the desk and his legs splayed out for all to see. His head was still aimed downward so that he was looking at his crotch. The girls were moving in a slight circle to get a better view of his soft penis. He wanted to yell at them, to demand what they should do and give him back his balls. Yet, he found himself remaining completely helpless despite what he might want. There was an icy fear that ran through his spine that they might not even be done with him. Greg's eyes darted back and forth between the girls who were watching him. There was a sense of dread with how interested they looked. A little lump grew in his throat that he tried to swallow down. A little bit of sweat beaded down his forehead the more that he thought of what they wanted. Each little droplet of sweat coursed down his body through his body hair. The more he thought about those staring eyes the more he felt the liquid draining down his back and chest. An itching that he couldn't scratch got worse with the sweat beading down. Now he could feel his entire body coated in sweat, the dripping wetness travelling down each valley of his body. Soon the hair that covered his legs seemed to slide with the sweat down onto the ground. He could feel each strange gently yanked out to slide onto the desk itself before he seemed to sweat it out to the floor. Each loose hair grew with every yank until he felt slightly sore against his skin. A slight red tinge was left from the removal of the hair before it settled. The redness left a slight paler skin underneath until it was easily a shade lighter than before. The view of his legs showed that they were now smooth, the redness from earlier disappearing before it became a flawless smooth texture that he could now feel every current of air from the vent with. He shivered. "Now humans aren't going to be perfectly hairless even when they aren't male. But, as you can see the reaction to the machine continues to make them a little more pleasing. No hair will grow beyond the eyebrows or head now. It's a perfectly normal human reaction." Dr. Good said to the girls who were nodding rather interested in watching more. She didn't seem to notice that she kept using the term human as if it were an abstract concept to her. As he watched them he felt a little strange tingling all over his body. There felt like someone was pulling against his skin. The discomfort got close to pain when it reached deep into his belly. Greg couldn't cry out, but his eyes grew wide when he heard the strange crunching noise right behind his head. His ribs felt like someone were compressing them. Deep breathes became more difficult to accomplish. The girls seemed to grow bigger in front of him. Without clothes, he couldn't see his arms, legs and torso growing into each other, inches of his height disappearing in front of them. His head felt heavy, before it too shrunk into itself. The halo didn't make a sound as Greg lost several inches from his height and size. Panic made his breathing more rapid before the cold brushed against the smooth skin of his nipples. They engorged into the cool air, filling with energy before they pushed outwards slightly as if someone were slowly pulling them towards the group of girls. A little cone shape formed with the nipples expanding around his chest before a little lump of fat grew behind them. Their color grew from a slight red to a lighter pink that matched the paler skin. The sensation felt odd with a little warmth spreading around his belly and expanding downward towards his ass. The desk felt even colder against it, his hips wrenching out in a slightly painful rush that was soon forced with the expanding of his ass. The flesh grew fatter with the flesh expanding outward with the new shape of his hips as the pear pushed against the desk. Each grain of wood could be felt from Greg with the motion that his ass made when it expanded making his body raise slightly. The flesh of his new girlish butt was something that felt better to be honest with his big nipples behind the tiny little breasts that were formed. "Now you can see the early secondary sexual characteristics form. Aren't they nice? See the little breasts and smooth skin," Dr. Good stated with a little relish before she ran her finger across his smooth leg, the calves becoming more pronounced under her fingers with the feet shaping into a smaller little form. The bones of his foot contracted until the toes were pulled slightly. Her fingers sent shivers up his spine. For a second he felt slightly detached. However, there were signs that he remained. Greg could still see the little scar across his knee, though the soft flesh that it was in now appeared to fade it slightly. Dr. Good moved his head even further down. She obviously wanted him to see what was happening to his dick. Greg's penis had shriveled into a flaccid state with the scrotum having pulled towards his skin. It's wrinkled form was right around the edge with the cock sucking itself downwards as it shrunk. Each breath made it appear that something was yanking his penis inside of his body. The thickness collapsed so that the member became thinner. Greg's scrotal skin now pressed completely against his groin. As he watched his pee slit grew flush around itself before it closed. The little threads of flesh sewed together before he felt his cock sliding backwards. In a few seconds, it was the size of his pinky. The color of his cock changed slowly from the regular pale complexion he now had to a reddish tinge. It morphed into a pale pink color, a wetness coating the newer skin before it slid under a little fold. The wrinkled skin of his scrotum had now filled with fat until with a strange gasp it burst open. The new flesh was pink, with the folds of the new labia shivering under the coolness of the air. Fat vaginal lips formed and pulled snuggly against his groin. The little tuft of hair covering his crotch had disappeared with the rest of his body hair, easily allowing Greg to see the little curve of his mons. Greg could see his new pussy, the way the flesh rippled underneath. To call herself a male anymore wouldn't work. The new girl was obviously female with the tiny little breasts, smooth skin, smaller size, and the warm wet pussy in front of her. Greg couldn't deny that with tears welling inside of her eyes. Those tears streamed down her cheeks to dribble onto her chest. Dr. Good moved to dip her fingers inside the new vaginal folds. Greg jerked back slightly under it involuntarily, the new pussy dripping with new sensations before she unhooded her clitoris. Flicking it with her thumb she forced her fingers deep inside of that lovely new virgin mound. Greg gasped again deep inside of her chest before her pussy contracted around those lovely fingers. Not prepared or used to it, Greg felt her very first female orgasm with her juices sliding down those lovely digits as her inner walls contracted around it. That didn't mean that Dr. Good stopped her movements, instead intensifying her fingers so that they dove even deeper. A new squelching sound filled Greg's ears with her rubbing of her clitoris sending jolts that shook her hips over and over again. The orgasm ran over her new body, making her gasp for air with the halo humming a little bit. Her nipples pushed out even more as the fat behind them expanded again. She felt her chest pushed outwards with a new energy that filled her entire body. A new weight pulled down on her chest, though they were still perky. Greg's new breasts sloped slightly downward so that they pointed towards the girls. They weren't perfectly round, but more natural to a girl her size. At a large B cup they felt like a new anchor to the world of femininity. Not that she could keep that in mind as her face felt like someone were slowly moving across it with playdoh. There wasn't any pain, just a disconcerting sensation as the bones and flesh of her face moved. Her nose cracked slightly before it shrunk against her face. Her lips plumped and rounded with a little curve at the top. Greg's eyes were slightly larger with a little edge to them. To anyone the petite girl would have looked perfectly normal for a girl of her sex. For a male, Greg didn't look male at all. A tickling sensation reached the back of her neck, a new itching against her scalp revealing the long locks of hair that cascaded down her back to her ass. A strange smell filled Greg's nostrils. She could feel her nipples harden and her pussy moisten at the scent. A rush of energy filled her body as she looked at the others. Why did she feel so horny? This was just so strange to her. "Ooh look she's reacting to our pheromones. Once the transformation is complete the male will react as any female will to us. That look of lust and loss means that she's ovulating as we speak." Her fingers ran across Greg's legs. She jumped a little, though not as much as she would without the halo. Dr. Goods smirk grew rather large. Her fingers danced around the curve of her mons, keeping from touching her pussy. Just her touch revealed how hot Greg felt. A deep breath filled her lungs. Being closer allowed her to get a better view of the doctor's crotch. The curve of the skirt now revealed a strange bulge. At that Greg could see the bulges in each of the girl's skirts. The way that they stared with lust at her made her blush slightly. What was wrong with them? Dr. Good and the others began to remove their panties in order to reveal the genitals they contained underneath. Greg would have let out a surprised gasp or something if she'd been able. The girls had thick 9 inch cocks attached to them. Dr. Good's shapely member had two heavy balls right underneath that pulsated with energy. All of them had a strange large mushroom cap that seemed to push out the foreskin without too much trouble. It expanded with every beat of their hearts. The girls licked their lips, the tongues extending outward with every motion so that she could see each of them could easily have reached their chin if they wanted. Now that the illusion was wearing off he could see all of them for the alien forms they had. Beyond just their long tongues and cocks she could see that each of them had long pointed ears that pushed their hair outward. Their forehead opened to a third eye that stared at her with a sense that they could have forced him to put the halo on himself. A sense of powerlessness filled Greg's mind at that moment. Whatever they had planned there was little she could do. Dr. Good was the tallest, her cock throbbing with attention. A pearly white droplet of pre-cum oozed past her pee slit and trailed down her member. "We now must fertilize the subject so that she may carry our young. Males are better for this because regular females do not ovulate immediately and aren't guaranteed fertile." Her fingers moved to spread her legs, that glistening human pussy there for her to enjoy. She rubbed her thick cock between Greg's new slit, making him gasp again before she forced the member deep inside. With a thrust of her hips she pushed past the virgin opening. The fat lips of the new girl spread apart for the thick alien penis. Greg took a deep breath. Every new sensation drove her forward, the pheromones making her head feel fuzzy. A thick cock sliding inside, spreading her insides apart made her feel wonderful. The lust and desire to mate was overriding anything that Greg might have had to resist. Greg moaned again, the halo seeming to beep again without removing any control. Her breasts bounced with every thrust of the doctor's dick inside of her. Her pussy opened and closed with every thrust, the tip just leaving the entrance of her new womanhood before thrusting deep inside again. The other girls were staring at her with those big eyes, the middle eye staring even harder. Each of them was stroking their own dicks, moving in little circles to get it ready for another one. Dr. Good turned to them with a glare that seemed to make them realize that this one was for her since she'd acquired him. Gasping for air she could feel that thick strange cock inside of her, getting thicker with every thrust. Her inner walls contracted against the lovely cock before her toes curled beyond her volition. Greg couldn't help herself with her body on edge till she came again. Her moans were deep inside of her chest, her breasts heaving with the energy. It seemed that Dr. Good wanted her to cum repeatedly with her thrust driving and massaging each area of her pussy. A throbbing inside of her belly showed that the mushroom cap of her dick had expanded inside of her. When the good doctor pulled back she couldn't pull out with her tip unable to be expelled. Her thrusts grew shorter with her balls swinging against her ass. Dr. Good moaned a little before she thrusted deep inside of the new girl's body. All three of her eyes closed before warmth suddenly spread inside of the new female. Greg gasped again with a little bump growing from the thick waves of semen cascading inside of her new womb. "As you can see the new female enjoys the experience," Dr. Good said between deep breathes, her body glistening with her own sweat before she licked her lips. "All of you need to remember that the process instantly causes fertilization and that you can't stall for time or let yourself be lost in petty emotions." Her thick cock tip seemed to plug Greg's new pussy. The other girls were stroking their own cocks, the tips expanding outward into the air with her eyes able to track the lovely enflamed cocks. Pre- cum was oozing past their mushroom caps until she felt the warm semen suddenly splatter against her breasts and belly. Each of them sent long waves of semen against her body. The new girl could feel the copious amounts of cum dribbling past her body. "Pregnancy will make her accepting of this new situation as we fill her with more and more of our kind. Eventually she'll forget anything other than her current existence. It's why the transformation is such an important process." Her fingers moved to remove the halo, turning it off with a small beep. Greg moved her hands to cup her new breasts. The smooth, soft flesh pushed against her fingers. Dr. Good moved backwards, her cock leaving her vagina with a wet plop that let a little stream of semen drip onto her thighs. She moved for the first time in this new body to feel the difference in weight. A few strands of her hair slid into her face, covering her eyes in a dark web before she felt the women's hands on her. She tried to weakly kick them away before they grabbed her arms and legs. Together the girls carried her past the door behind the teacher's desk with the doctor following after. None of them seemed concerned that all of them were naked. The hallway past the door that she'd ignored when she first entered led down towards a pair of stairs that went deep into the school. There didn't appear to be anyone here, and the structure of the walls seemed almost alien to her. After a few doors they entered into a room with a set of 10 chairs on each side. There was a slight glowing blue light that filled the room. Only one of the other chairs was occupied with a girl who was in the later stages of pregnancy. The stirrups lifted her legs so that her pussy was open to the air. A few electronics were set that showed Greg that the chair itself might deal with every need that the woman needed. The girls moved her towards one of the vacant chairs, lifting her until she was now plopped right into it. Pushing a button Dr. Good secured her. Greg could feel the way that it vibrated when it moved her legs outward. She could stand up from the thing if she wanted, but felt with the sound of that light that she didn't feel like it. Her wardens left the room, closing and locking the door behind them. Greg stayed in her chair without a word. There didn't seem to be any need to say anything to the girl next to her. The unconscious woman stuck with her belly rumbling until the machine covered her to give her some privacy during her labor. Greg felt lonely after that before she saw the hour's tick by. With every hour, she felt a churning inside of her stomach. Her fingers played with her belly after the fourth hour expanded her stomach outward. With every passing hour, she went through a months' growth for the child inside of her. Her mind wandered to how many babies they'd take from her over the course of a day. She felt a strange fogginess come over her mind the more that she thought about it. There almost appeared to be a haze that made her enjoy the thought of living like a womb for these creatures. The very thought making her pussy ache for another session.
