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.
