--------------------------------------------------------------------------------------------------------

Jack's head slipped from his hand, and he quickly jerked his head upright, waking himself up. He was dozing off in class again. Psychology 101 wasn't the worst class he'd ever had, but it wasn't entertaining enough to lift him out of the funk that he was in. Nothing seemed to be working out. All these classes were boring. Not to say that they were easy, just none of them excited him anymore.

No one even noticed him falling asleep. They are roughly 200 people in the room, and he might as well be invisible.

When class was finally over, Jack slowly got up and walked to his next class. After two more classes, he got in his car and drove to work. He works part-time at a computer-electronics store. Most days, he tries to avoid customers and any trouble that comes from the managers. Once the store closes, his shift is done, and he goes home. Walking into his dorm, no one else is around. They're probably all out partying somewhere. Jack walks to his room, closes the door, works on some homework that's already late, and then searches for some porn to watch as a reward for finishing the day.

Jack is in a rut. After his girlfriend broke up with him three months ago, it seems like nothing is working out. There are plenty of girls he likes, but he always puts his foot in it around them. His friends still hang around his ex, so he avoids being around them too.

The next day, Jack wakes up and performs the same routine. Go to some classes, go to work, jerk off, go to bed. Every day is another round of school, work, jerk, sleep.

One night, as he reached for a tissue to catch his load, the box was empty. Needing to think fast, he grabbed a cup on his desk and shot into that. Exhausted, he left the cup at his desk and just went to bed. The next night, forgetting that he was out of tissues, he realized the same cup was still there and figured he would use that again.

To lazy to buy a new box of tissues, this became his new ritual, cumming into the cup every night before bed. He started to wonder how long it would take for him to fill the cup. Honestly, it was the only thing he looked forward to anymore. It became a new challenge to blast as much into that cup as he could.

The cup was filling fast. Every time he looked, it seemed fuller, even if he had not came yet. There was a good chance it was full of bacteria and growing something, but it didn't look or smell weird. He figured that once it was full, he'd dump it out. If it could just last a few more days without getting gross, he could accomplish his goal.

Just when Jack thought he only needed one or two more nights to fill the cup, he got settled in to jerk off and it was empty. 'Did someone find it and dump it out,' he thought. It didn't look that bad, but it was a large cup of cum. He always kept his room locked, so it seemed strange for anyone to come in. Plus, if they did, why would they only dump out that cup and do nothing else? He searched around the room wondering if he moved it, switching the cup with this empty one. 'Shit, I didn't drink it, did I?' he thought, and then felt ridiculous to think he guzzled down a whole cup of fermenting cum without realizing it. He cleaned up around his desk and the floor, checking to see if there were any spots. Worried mostly that he might not get his deposit back if it ruined the carpet. Frustrated by losing his streak, and motivated to tidy up after realizing how bad his room had gotten, Jack didn't even jerk off.

Tired from cleaning his room, he finally went to bed. That night, he dreamed of his ex-girlfriend. He loved her body. Her personality was what he was glad to get away from.

In his dream, she tip toed into his room and whispered in his ear, "Let's fuck one last time." She stripped down naked and ripped off his shorts, straddling him. With one hand, she guided his cock into her pussy as she squat down on him. He could tell she was desperate for him. She was so wet his cock slid right in with ease. She moved up and down on top of him with a steady rhythm, her body jiggling in the air. She never let herself slam all the way down. Instead, she kept herself elevated above him, gracefully squatting and rolling her hips while touching only on his cock. This was by far the best fuck they had ever experienced. She had been on top only once before, mostly just hovering over him as Jack thrust into her.

Jack lay back with his hands behind his head, relaxing while she did all the work. She grabbed the bottom of her breasts and bounced them up and down, not to support them as they shook up and down, but rather to bounce them even more while expertly balancing above him. He loved her breasts. She was average in build, with no hips or ass, but her D-cup breasts were exceptional. She always wore push-up bras with extra padding and low-cut tops that enhanced what she had, making her appear two cup sizes larger.

Her movements were precise and controlled. Her pussy clenched his cock and stoked it and she bounced faster on his cock. She bit her lip and furrowed her eyebrows as she stared at Jack. "I need your cum," she begged in a desperate voice while shaking her tits. Hearing her say something, she would've never said before, pushed him over the edge. He thrust his hips, driving his cock deep, exploding his cum into her. Her eyes rolled back in her head, and for the first time, she lowered all the way down on him. Still not putting much weight on him. She reached a hand down to her crotch, with her body trembling, as Jack emptied his balls through each pulse of his cock. Jack shot his final load into her, as she rubbed her hands as if she could feel the warmth of his cum inside her. When the last twitch expelled the final drop of cum, she disappeared. The lights in his room went out, leaving Jack alone in the darkness.

He blinked his eyes a few times, realizing it was all a dream, and he was now awake. His cock felt warm and wet. Startled, Jack reached down to check if there was a wet spot. Even in his teens, he never had a wet dream. Slowly, he slid his hand under the elastic of his boxers, feeling nervous about what he might find. Sure enough, his fingertips met a thick puddle of cum.

"Fuck," Jack said, frustrated that he'd made a mess in his pants. Jack got out of bed and waddled to the bathroom, where he removed his shorts and boxers, preparing to catch his morning load dripping down. As he slid off his boxers, he was surprised to find no cum dripping down. His dick was lubricated, as if he'd been stroking it, but there was no puddle or mess. Whatever he felt a moment ago was gone. He figured what he felt was only pre-cum, and it must have absorbed into his shorts.

-----

Jack went about his day as he usually did. He attended some classes, went to work, and then returned home. He looked at some of his homework and got one of his assignments done, before putting the rest aside for another day.

Again he didn't masturbate like he usually would. He wasn't feeling particularly horny. All day, he felt a sense of satisfaction from whatever had happened the night before.

Jack fell asleep quickly that night and had another intense dream. He was on a beach, lying in the sand when he rolled over and noticed his freshman English professor sunbathing. She was quite a bit older, but her dark Latin skin and curves always drew his eye. Now, as she lay in the warm sun, he could see the flawless, smooth skin, that she had been hiding underneath her work attire. She looked amazing. There she was lying on her side with her big ass pointed right at Jack.

He hated that class, but every time she would turn to write on the board, he would get an erection. She had wide hips, and he spent every class staring at her ass, waiting for it to jiggle slightly when she shifted her weight. One day, she wore a nice top and a short skirt because she had an event after class, and Jack wished she would bend over for something. She never did.

This dream was even better, she was wearing a thong, and her ass was out on full display. It should have been flabby or have cellulite for being that large, but it was not. It was firm and round, and so was the rest of her skin. She was so hot.

"Do you mind?" She asked as she handed him a tube of sunscreen. Jack complied, rubbing a large squirt of white creamy sunscreen onto her side and back. "Don't forget down below," she said. Jack nervously gulped and squeezed out another line of lotion down her thigh, then massaged it onto the sides, front, and back of her leg. He was turned on and terrified as he worked his hands up her thighs close to the bottom of her ass, and near the front of her bikini.

"You still missed a spot," she said, as she slapped her ass, making it ripple from the impact. Jack got hard just from the thought of touching the ass he previously longed to even see like this. He rubbed some lotion between his hands as he knelt next to her glorious ass. As soon as his hands touched her big butt, she reached back and grabbed the elastic of his swim trunks. Jack froze, assuming he was not supposed to touch her ass after all, but instead she tugged on his shorts and pulled them down. As his lubed hands slid around her buttocks, she grabbed and tugged his cock.

She jerked him a few times, to ensure he was hard enough. "Just fuck me already," she ordered, as if she were desperate to have him inside her. Jack didn't hesitate and quickly slid his trunks off, and lay behind her. She lifted one leg slightly, grabbed his cock, and guided it into her pussy, pushing the fabric of her thong aside.

She felt loose, like they had been fucking for hours. His cock slid right in, but she knew how to use her pussy and flexed her muscles around him. She laid there on her side, but it felt like she was stroking him as her contractions rippled up and down him while he pushed in and out. Jack pumped faster, slapping his hips into her lubed lotion covered ass. He pulled the knot on her bikini top and slid a hand under the fabric to squeeze of her tit. "I want your cum, fill me," she said, tightening her pussy in a way that felt like it was milking the cum out of him. Jack couldn't hold out and came hard, giving her the hot blast of cum she desired. Lightly thrusting with each jolt of his orgasm, he threw his load deep into her. As pulses of cum from his cock faded, the bright sun on the beach faded too, and Jack was left in the cool dorm room.

He was lying on his side, similar to the dream, but his hand was squeezing his pillow next to him, not her breast. His shorts and boxers were pulled down this time. He must have acted out the dream and taken them off for real. His dick felt wet again, and his hips were pressed against something. Jack reached down and felt something slick, wet, and squishy. It wasn't just a puddle of cum. It was firm and jiggly, like gelatin.

Confused Jack pulled over the covers and looked down. It was too dark to see anything. As he felt around again, it was gone. He got up and turned on the light. There was a small wet spot on the sheets, but nothing explained what he felt. If he had cum in his sleep that small spot would have been larger, not to mention what he felt was large enough to rest his hips on. Jack looked around the room, checking if something fell off or rolled under the bed, but found nothing. He gave up and figured he must have still been dreaming when he thought he touched something. Jack went about his day, going to school and then to work like any other day.

---

At work, a girl was browsing through the headphones section of the store when she noticed Jack checking her out. In the past, Jack would have walked away to avoid any awkward moments, but today he felt bold and walked over. "Can I help you?" he asked. "I'm just not sure which of these would work with my phone," the girl said a little annoyed. She was gorgeous. Sure, Jack was desperate for a girlfriend, but she really was beautiful, and way out of his league. "Let me see your phone, and I can check," he offered. "Here you go," she said as she unlocked her phone and gave it to him. Jack went directly to the contacts and started typing in his number. "All the headphones we have will work with your phone fine," he said, saving his phone number as 'Jack tech help'. "If you need anything just give me a call," he said as he handed back her phone.

"Um, okay," The girl said as she grabbed a pair off the shelf and walked to the checkout, turning around and looking at him slightly confused as he was walking off.

Jack's heart beat out of his chest. He was never that forward with girls before. His ex and him were set up by friends, and he would have never had the courage to ask her out. Today he feels more confident, and less concerned about getting rejected.

After work, he went home. He laid in bed and watched some TV. He fell asleep in the middle of an episode, and another vivid dream started, just like the nights before.

He dreamt he was back at work, and the girl from earlier found him stocking the shelves. She walked up and grabbed his belt. "I never thanked you for your help," she said as she unbuckled his pants and pulled out his cock. She got down on her knees in the middle of the store and sucked him into her mouth. Jack braced himself on the shelf next to him as he looked around, making sure no one was watching them.

She gave him the best blowjob of his life. Her mouth felt like a pussy as she slobbered up and down, going deep and forcing herself all the way down to his base. Wet slurping sounds filled the store as she held his waist and used it as leverage to slam her mouth on his cock. Jack was about to blow getting deepthroated for the first time, but he didn't want it to the end.

"lay down," she said, as she unbuttoned her jeans and took them off, throwing them on the store floor. Jack complied and laid on the cold floor with his pants at his ankles. She guided his cock directly into her pussy, which slid in smooth and deep as she lowered herself all the way down and sat on his hips. Jack grabbed her hips as she bounced on his dick. The floor was hard, but the hardness didn't bother him. All he could notice was how good she felt around his cock. Jack squeezed her thighs, enjoying how soft and squishy they were while still being firm.

"Yes, fuck me, I need your cum," she said, grinding her hips back-and-forth against him. Wet, squishy sounds echoed in the aisles of the store as the customer began to moan, not caring about who might see or hear. Her pussy clamped down so tight it practically sucked him off as she rose up and down.

Jack was close to climaxing, but he kept getting distracted. He was nervous that a manager would find him or another customer would come around the corner any second. The girl needed to maintain his attention. She spun around, never lifting off his cock, and squat down with her ass on display. Her round ass bounced up and down as she shook it tempting Jack. He grabbed her ass and he sunk his fingers into the mounds of flesh in front of him. Jack started thrusting up into her, matching her movements and it finally put him over the edge. He Squeezed her ass tight and flexed his ass driving his deep as he released his load. "Yes, give it to me!" she said as she sat down and wiggled her hips as pulses of cum shot out of his cock.

The lights in the store went out, but the girl didn't disappear. Jack expected to wake up alone with something wet in his lap again. Instead, the girl was still there and continued to move up and down on his cock.

Excited by the situation and the firm grasp on his cock, Jack started to get hard again. He was still holding her ass as she slowly worked up and down again.

Jack was so confused. This has to be a dream. There's no way that girl would start fucking him in the middle of the store or that the lights would go out and say so quiet. But why didn't he wake up when he came? 'I guess this dream just requires me to cum twice,' Jack thought to himself and began getting hard again. As they moved, he realized the hardness of the store floor was gone and replaced by the soft sheets of his bed. He looked around and could see the LED lights from the devices on his desk. 'I'm not in the store anymore, so I did wake up,' Jack thought to himself. 'But the girl is still here, so I must still be dreaming,' he confused himself. 'Shit, who cares, I'm fucking this hot girl,' he concluded in thought as he grabbed her ass and started thrusting into her again.

At this point, Jack didn't care if it was real or not. Her ass felt so good in his hands, and his cock felt so good in her pussy. She picked up the pace as she tightened around him even more.

Even though he just came, he knew he would not last long. His senses were overwhelmed by the idea that the girl from the store came home with him. The dream was so real now they were in his bed. A few thrusts more and he was at his limit. "I'm going to cum again," Jack said, but the girl didn't say anything. She slowed her pace and squeezed her pussy around him as his cum splashed inside her. She shifted her weight and pushed down on him with more force after each blast. Damn, she was good at this, Jack thought.

As his cock softened from is 2nd orgasm, she pulled off his cock and slinked away from the foot of the bed. It was still dark in the room, with only the faint glow of early morning light illuminating his blinds, and he couldn't see where she had gone. Exhausted, he slowly got up and turned on the lights, but she wasn't there.

Jack went to his bathroom to see if she went there to clean up, but she had not. His cock still wet from her juices, he wandered out of his room into the shared living room area shared by the four joined rooms. He never even put his pants back on, figuring everyone else was asleep. She was nowhere to be found.

Back in his room, Jack was confused. What situation was more strange; One, that the girl was never there, or two, she had been teleported into his room from the store. His mind was racing faster than usual, trying to make sense of everything that had happened. He could have sworn he both felt and saw something, but it must have been a dream. Plus, he he absolutely just came, and wondered why there wasn't any evidence of cum in his bed.

It was still early, and he should just go back to sleep, but after everything, he was wide awake. He showered and went to class early, wanting to distract himself from what had happened.

-----

Jack was one of the first to arrive at class and took a seat closer to the front because he had never been early enough to get anything but the back row. A girl walked in and sat down next to him.

"Did you just join this class?" she asked. "No, I've been here all year," Jack said. "Oh, I've never noticed you before," the girl said. "Probably because I'm usually late and sneak in the back," Jack said. "Well, good job, getting here early for once," the girl said.

She had an average appearance, petite with dark hair. She was not curvy, like the girl at the store, but her face was cute.

"Are you ready for the final next week?" she asked. "No way, I'm gonna need a lot of help," Jack said. "That bad, huh?" she said. "Yes, if you can give me any tips, I'll take it," Jack said. Before she could answer, the professor walked in and started rambling.

Class was boring but Jack tried hard to pay attention this time and stay awake. He didn't want to look like an idiot next to the girl he'd just met.

After class, he said goodbye to the girl. "See you tomorrow. Hopefully, this will all soak in," Jack said. She waved goodbye as Jack walked out of the room, parted her lips as if about to say something, but Jack had already left. Jack went through the rest of his classes, trying to pay more attention and catch up on things he missed.

He didn't have a shift at work, so instead of leaving campus, he sat at a table outside and looked over the coursework he had to do. Jack spent some time reading over a science lesson, but was mostly distracted by watching other students walk to and from their classes. The weather was nice, with most people wearing shorts and T-shirts. Whenever a girl with short shorts walked away, he peered down to see if any part of her ass poked out the bottom. Or when a woman with large breasts passed by in a tight tank top, he pictured her without her top.

Not every girl that walked by was good-looking, so Jack managed to get some work done. One girl came by that made sitting on the bench totally worth it. She was jogging in just a sports bra and small tight shorts that looked more like underwear. Her large breasts bounced up and down as they pressed together, trying to jump out between the straps of her top.

Pretending to be absorbed in his book, Jack was actually staring at the bouncing jugs, which were getting closer and closer to him. She had her hair back in a ponytail and it swayed side to side with each bouncing step she took. Her waist was on display, fit and slim, with the curves of her hips flaring out. As she ran past, Jack was tempted spin around quickly to check out how her ass looked above those golden firm thighs.

He paused, then pretended to stretch, twisting his torso to get a better view of her perfectly rounded behind as it jiggled and bounced, as glorious as he had expected. Jack turned back to his book and realized he couldn't study anymore after that. He waited a moment, just in case any other college beauties were about to come around the corner to give him another visual delight. Without anyone new to look at, he got up and walked back to the dorms.

Inspired by the jogger, he looked up some fitness instructor porn and pulled out his cock. A few strokes in and, his dick was totally wet. He knew he was horney from seeing the jogger, but shocked by the amount of pre-cum that lubricated him. He could feel the pre-cum dripping down his leg.

He figured he was just really worked up after seeing that sexy college girl bouncing toward him. As he thought of her again, his dick swelled larger and larger. It was the hardest he had ever been, and it seemed like his dick was growing. His fingers seemed to separate with each stroke.

He looked down to see if it was larger. It wasn't just his dick he was holding. Covering his dick was a film of rubbery white goo, and it was growing thicker. It wasn't his precum dripping down his leg. In actuality, the white goo was crawling up his leg and globbing around his cock. The flow was increasing faster. Jack let go and scooted backwards in shock.

There was a puddle under his chair, connected to the ball growing around his dick with ropes of sticky liquid pulsating between them. Clumps and ripples from the puddle on the floor crawled along the gooey ropes and gathered around his cock. The ball of goo slid up and down his cock, just like the hand job he had been giving himself seconds ago. Freaking out, Jack grasped the mass of goo that was still stroking his cock and tried to pull it off. He only managed to get it to the tip of his cock before the white slime ropes, connected to the puddle on the floor, contracted and slammed the mass down to the base of his cock.

The inside of the ball was squeezing his cock tightly as it slid down, completely engulfing him. "Oh, fuck," he said, hunching forward with a groan of pleasure as he held the growing white ball. He was kind of freaking out, yet the sensations on his cock were impossible to ignore. The ball was growing, and the puddle on the floor was shrinking. The mass on his cock was now as wide as his hips, preventing it from moving due to its weight. The insides pulsed and stroked him, creating ridges and valleys in the gel-like substance that slid along his cock, as the entire mass remained settled on his hips.

Jack held the ball as it gave him the most intense stroking, but then it began to bubble and soften, almost like it was melting. It transformed and stretched until it started to firm again in a new shape. It solidified into hips and legs that stopped at the knees and waist. The legs flexed and pulled away from the chair, sliding up and down his cock. The goo was now silky, shiny white, resembling the smooth curve of a woman's lower half as it fucked him.

Jack grabbed the hips of the white slime crotch and again tried to pull it off him. The weight of the object was heavier, and he only helped it give a fuller, longer stroke. As he lifted it to the tip of his cock, the waist shrunk, and he lost his grip, causing it to slam back down. It felt like the tightest, wettest pussy he could imagine, and it now looked like one too.

The puddle on the floor was gone, all the white liquid was absorbed into soft thighs and ass fucking him. Jack thought it was odd getting fucked by a white slime blob, but also thought it was kinda hot, now that it looked and felt like a woman. "If only it had tits too," he thought. Looking at the mid section with a flat top where a belly button would be, made it hard for him to get into this.

As if the figure could hear his thoughts, the flat surface capping the waist line inflated. The object didn't grow. It literally inflated with air, extending the waist upward into the torso of a woman. It continued to fill out into shoulders, though without any arms. Only a fint outline of breasts were visible, but the shape of the shoulders, collarbone, and rib cage was well-formed. Where a neck would have been, it was rounded over, there was no head.

The woman continued to bounce up and down on his cock. Jack held her waist, becoming less concerned about how weird the situation was and more intrigued by what he hoped would happen next.

Jack yielded to the sensation of the white plastic inflated figure pressing against him as he leaned back in his chair. As she worked her pussy against him, the two small breasts started to fill. It reminded him vividly of two balloons being pumped with air. The bottom half of the figure was heavy with liquid, giving it a creamy, pearly-white appearance. The top was like a blow-up doll, but the skin thicker and milky-white, slightly more transparent than a plastic milk jug.

Each time she lowered herself down on his cock, the breasts grew a little more. As if his cock was pumping her up, filling that cavity with more air, and blowing into the breasts. The breasts became large and full, and even though they only filled with air, they weren't round like a balloon. They hung from her like heavy tits, and bounced like they were real, as she rode his cock.

Jack realized this slime girl was the same dimensions as the girl he had seen jogging moments before. Her large double D, or even triple D breasts, were now right in front of him. They weren't the tan skin of that college girl, but if he ignored the translucent color, he could enjoy them all the same.

Jack reached up and grabbed both inflated fun bags and thumbed the small nipples as he did so. The texture was somewhat rubbery but not far from skin, similar to a leather seat, hairless and smooth. The clear white color, her lack of arms and head, and the fact that she had no arms of head made it hard for Jack to lose himself in the moment completely. He closed his eyes, burying his face between the breasts, as she ground against him. The warmth of her body distracted Jack from the thought that these moments might be fake. He moved one hand to the small of her back, holding her steady, while the other rested on her ass. He finally got to squeeze the ass that had jogged past him earlier.

Jack imagined he was fucking the girl right after her run. Her wet pussy wrapped around his cock as she bounced her round ass and big tits for his pleasure. Jack was lost in the illusion completely overwhelmed with bliss. His pleasure peaked and he squeezed her tight as he came. His head still resting in her breast, he moved both his hands up her back to hold her shoulders and pulled her down as he ejaculated his load into her. With the last spurt of cum, he opened his eyes, still pressed into the cleavage of the figure.

He was surprised to realize he could see through the semi-clear frame and watched his cumshot slash into the milky liquid inside her. It swirled and mixed with the fluid resting in her, filling her.

Seeing his blast of cum inside the pool of white liquid, it was now clear what had been happening over the past few nights. He had just had sex with his own cum. That blast from his dick was another splash of semen added to the large pool of cum inside her. The smell was missing, and the texture had changed, but the act of filling her was exactly like when he would fill that cup. What was in that cup did not disappear. It kept growing and returned every night to grow more.

The fluid inside her was higher, rising slightly above the belly button. There was no way he came enough to raise the volume a couple of inches. This thing wasn't merely getting filled with cum, but it fed off of it, multiplying the volume it consumed and growing rapidly from it.

Jack came down quickly from his orgasm and regained his composure, realizing he was holding a thick big titty glob of semen. Fully aware of the situation, his dick softened, and his mind raced to figure out what to do.

The figure seemed agitated, likely sensing Jack's thoughts on getting rid of it. It wiggled its hips, attempting to revive Jack's focus on the pleasure it could offer.

Jack pushed it from his cock and the figure slid down between his legs. He figured it understood his rejection, and was going to go back to wherever it had been hiding.

As it slid down, it got stuck with the large breast resting on his crotch. Jack grabbed the tits to push them off. But as he touched the soft boobs, arms inflated off the once bare shoulders, and new delicate hands grabbed his hips. Next, a head emerged, with a face just like the jogger's, with a mouth that was open and bending to suck his cock. The white transparent skin was like he was seeing her ghost. Her hair was slicked back in a ponytail, just like the jogger's, but the texture was like a rubber molded doll.

She lowered her head all the way down and took his cock into her mouth. She sucked it hard, firming and thickening his cock in her mouth regardless of whether he was aroused or not. Then she worked her tongue around the head, and licked side to side as she sucked and bobbed her head. Jack was starting to enjoy the feeling and watched her work. He could see through her skin and, although somewhat obscured, like looking through a stretched-out balloon, he watched his dick slide past her lips, against the roof of her mouth, and then down her throat. Yes, it was odd face fucking a living pile of his cum, but that was the hottest thing he'd ever seen. There was nothing beyond the throat. She only created what was necessary to suck him and keep him hard.

Jack gave in to the pleasure and did more than just let her suck him. He scooted to the edge of his chair, spread his legs, and held on to her ponytail as he fucked her mouth. One hand was on the top of her head to push her down on his cock, while he pulled her back up by her hair. He could feel her tongue swirling around his cock, and her lips were stretched around his dick. She was happy to get him lost in lust again, and ran her hands up his chest and down his back. He would never be this rough with a girl, but this was not a girl, it was a cum hungry slime shape-shifter and he wanted to give her more cum.

It felt so good, but he wanted to grab those big breasts, and he was not sure how to do that. He hunched over her and ran his hands down her back and felt the sides of her tits bouncing under his legs. She knew what he wanted and rotated. First, she lay on her side as she put one hand on the ground and raised one boob to his knee with her head tilted on the side. Then, for the final maneuver, she rotated the rest of the way and arched her back while she sat on the ground with both hands beneath her head. Her tits were now displayed in full, pushed up at him as she sat leaning backward into him. He grabbed what he desired and squeezed. She kept rocking on his dick, but the new position made it hard for her to do much more than hold herself up. Jack was ready to take over. He slid slightly and knelt down in front of the chair, pushing it back. He grabbed her breasts and used them as handles as he thrust his cock into her mouth, as she arched her back. He pulled out far and slammed it back in, now able to drive in and out with long, full strokes. His cock slid along her tongue, framed by her jawline, and bulged out her throat. Jack watched through her clear, milky skin as his cock moved in and out of her throat, seeing how his cock pinched and expanded as it passed through the narrow and wider parts of her mouth. He couldn't last anymore. He placed one hand between her tits and the other under her chin, holding her still as he came with one final thrust. He felt the blast of semen hit in her chest and felt the ripple between her breasts. She tightened her lips and licked her tongue as he unloaded into her, filling the emptiness with his cum.

Once his cock was empty, spent he rested his head on his desk and she softly licked his cock clean, ensuring she got every last drop. When done, he could only feel the cool air on his moist cock. He looked under the desk, and she was gone. "Fuck, that was hot. Kinda creepy, but wow, was it incredible," Jack said to himself.

Jack was physically exhausted but mentally still on fire. He went to the common living room area and turned on a video game. Later, when his roommates came home, he asked if they wanted to join, and two of them did. They played a few games until one of them said they needed to do some homework before bed, and they all went to their rooms.

Today was a pretty good day. It's amazing what having sex a few times can do. If you can call fucking your own pile of cum sex.
