No luck finding the above story. Not much of a writer but I was messing around with an AI generator and adding bits to guide it along… here’s my best Approximation of recreating that story from memory.
Ben and Dan are roommates in college. Dan is athletic and tall, dan is on the basketball team. Ben thinks Dan is attractive. Dan is sleeping as it’s well after midnight when ben walks in. Ben hears Dan talking in his sleep.
Ben gets closer until he hears Dan say “yeah, take that big dick” to someone in his dreams.
Ben laughs. Dan must be dreaming about that girl from his chem class that he was talking about.
Ben’s tired but he can’t pass up this chance to mess with his horny roommate. “Oh yeah, fill me up with that huge cock, Dan!” Ben manages to get out while trying not to laugh and wake him up.
“Yeah babe you love this big cock inside you don't you?” Dan says.
Ben falters. Is Dan awake? Did he hear Ben? He needs to test it out. “Yeah baby, it feels so good. You’re so big.”
“Yeah, Ashley, you feel so tight around me.” Says Dan to his dream girl as he tossed around in bed, in the process pulling the covers off of his midsection. Dan’s grey boxer briefs are exposed to the dim moonlight coming through the dorm window.
Now Ben and Dan had been roommates for long enough, they’d seen each other in their underwear plenty of times. Ben wasn’t afraid to admit he’d scoped Dan out before. Dan definitely didn’t have anything to be embarrassed about but it also wasn’t anything massive or too noticeable. That’s why Ben was really confused.
There, attached to Ben’s perfectly average roomie, pulsing under the fabric of his underwear, was a BIG bulge.
What the hell?
A quick glance over at Dan shows him still asleep.
Did Dan hit a growth spurt? Maybe he’s a grower, not a shower. Now curious, Ben continues the role play Dan’s dreams.
“Yeah babe, you’re huge! You’re way bigger than my last boyfriend and he was 8 inches long!”
This time there’s no mistaking it. Ben sees the fabric of Dan’s briefs distending as the monster inside begins to take up more space. Ben can’t believe it. Dan’s cock is growing! It looks like he may have grown two inches in the last 30 seconds.
No longer trying to imitate Dan’s dream girl, Ben blurts out “holy fuck.”
“Dan, how big are you??” Ben asks.
"I dunno," says Dan without opening his eyes. Shit.. Ben thinks. “I need to fix this. He’s going to wake up and freak out. It’s definitely my fault, now how do I undo this?”
Ben pauses. Who doesn’t want a bigger dick? Besides, Ben appreciates the eye candy. He’s always been a size queen even if he never fully admitted it to himself.
“Dan dude your dick looks bigger, I think it’s been growing. A little.” God Ben hopes this works “how big was it the last time you measured?”
“Umm.. I don't remember exactly. Maybe 7.5 or so.” Mumbles Dan as he continues to lay there. His penis still swollen, stretching the fabric of his underwear and bulging under the waistband. Ben assumes Dan is embellishing that number, what guy wouldn’t? But that sounds like a healthy starting point.
“Bullshit dude, you were average just like me. Maybe slightly above average. But that think definitely looks like it’s 7 inches now.” Ben is happy the desperation in his voice wont be heard by anyone but sleepy Dan.
Sure enough, the subject of Ben’s absurd experiment responds, the bulge threatening Dan’s underwear begins to recede from the realm of the fantasy down into more respectful, but still definitively ‘big’, territory.
“Yeah man it’s a hefty piece.” Dan murmurs.
Ben is sweating. “I can’t believe that worked.” He continues to eye the meat in Dan’s underwear. Ben’s happy things seem to be under control now but he can’t help but feel like he’s made a mistake now. Is 7 inches enough? Maybe this doesn’t have to be the end of his experiment…
“For sure. You’re lucky, Dan. You cock is big. Especially since it barely shrinks at all when you’re soft.” Ben’s trying to balance his desires with Dan’s ability to cope with the changes. “You’re like 5 inches long at your absolute smallest so you always have a bulge.”
Dan laughs “yeah, that’s why I’m so popular in the locker room”. Perfect, Ben thinks. The bulge in his roommates drawers hasn’t changed. He still has a boner, so it makes sense that messing with the soft size wouldn’t change it. He guesses he’ll have to wait and see the results of that change later.
“I’m jealous, you’re lucky to be swinging that meat around. It’s thick too, not to mention those bull nuts, it’s a complete package.” Ben feels the heat in his chest, he can’t believe this is all happening.
This time though, Ben can tell a difference in Dan’s pants. The bulge widens a little bit, stretching the fabric slightly. While between Dan’s legs, two eggs begin to inflate, like they’re being filled with water, as Dan’s sack expands a little more than Ben expected. It stops when Dan’s nuts look to be about the size of a large lemon, each.
Now Ben can see how much Dan’s penis has grown from earlier. It was still hard now but even soft the thing was definitely going to stretch Dan's briefs. Ben felt an intense rush of arousal at the thought of Dan’s reaction when he wakes up in the morning to find his new and improved package. Would Dan notice? How much bigger is his soft bulge going to be than before?
“Yeah dude, that’s why the guys on the team call me the bull!” Dan said. He knew full well the reason for his name, but now his cock seems to agree. He couldn't deny how nice he looked, the extra weight of his balls making his penis look thicker. Maybe the guys really were right about him being more hung than the rest.
Ben nods, unable to take his eyes off of Dan's bulge. That’s definitely a fitting nickname. Ben’s exhausted from all this experimenting..
“No doubt, well all I can say is it looks like The Bull isn’t done growing!”
Dan murmurs and rolls onto his side.
***
Dan wakes up next morning his body feels strange.
Dan is always careful not to sleep on his stomach so he doesn't snore too badly. When he moves to turn over to his back this morning, there is a slight twinge in his testicles but only one. He notices a slight ache down there that wasn't there last night. This makes sense to him, though he is surprised he was able to sleep like that for an entire night.
As he sits up and stands to get dressed for class he notices something else. The bulge in his underwear is considerably bigger.
He looks to the mirror and can't quite believe the difference. While it still isn't the biggest bulge he's ever seen, he has never had such a big bulge under his briefs. Dan thinks maybe it had something to do with him sleeping wrong, could it just be some temporary swelling? He looks into the mirror again. Definitely bigger. But he’s already late for class and doesn’t have time to dwell on it, or to shower for that matter.
His testicles feel heavy. He feels the weight of each one as he pulls up a pair of sweatpants over the same pair of underwear as the night before. Then there’s his dick. His penis seems larger too, and not just in length. It looks thicker, a lot thicker. It feels heavier too, as if it had been pumped full of liquid. Dan reaches down to adjust himself. His dick was hanging down making an obscene bulge. His dick seems plump, like he had a semi despite not being aroused at all. It was pushed out even further by his balls. He tried to rearrange it so it didn’t stick out so far, settling with pulling it up to the side along his hip and tightening his drawstring.
"Damn, this might be a problem today"
***
Dan arrives at the gym. It had been a long day in classes but at least Dan made it on time to the first one. Tuesdays were always a full course and he found himself preoccupied with the lessons. He was happy to have made it through the day, now he could let off some steam in the weight room.
> You dan changes into workout gear.
Dan takes off his clothes and puts them in his locker. He lowers the waistband of his underwear he’s been wearing since last night, and checks the state of things down south.
The sight of his flaccid penis surprises him. He hadn’t realized until then how large his dick looked, especially compared to his balls.
His dick looks huge. Not just thick, but very long, as long as his boner normally is. Dan wonders if his jockstrap will still fit. He pulls it up over the heavy bulge and notices the straps are tighter than usual, they barely come together around his hips. As he looks down between his legs, he sees that the outline of his dick is clearly visible beneath the fabric of the jock. There's no hiding the fact that he has a pretty impressive member.
Dan throws on his shorts and walks over to the weights.
“What’s up, Bull!"
Dan turns around and smiles at his friend Josh. He gives him a high five. "Sup, J-Dog."
Josh grins, "You're looking good man! Ready for a workout?”
Dan shrugs, "Yeah man, let’s do it! Chest day?”
Josh laughs, "We'll work your pecs tonight. Let me show you my new routine!"
Josh leads him over to the bench press.
While Josh works on his own set of reps, Dan watches him closely. He's impressed. Josh's technique is impeccable, and he manages to lift more weight than Dan expected. He must be doing a different rep scheme than Dan is used to, because his numbers look great.
"How many sets?"
"Five."
"Good job! Keep it up."
Dan keeps watching Josh as he lifts, taking note of what he does. He's got a nice grip, firm yet relaxed, and he seems to know exactly when to start and stop lifting.
When he's finished his set, Josh says "This is where you start your workout. If you've done your warm-up properly you should have warmed up enough to hit the weights hard without risking injury. Now, you want to use this bar here for the entire exercise. Grip it firmly. Squeeze it, don't just grab it.
Dan gets on the bench press and begins working his arms.
"Okay," says Josh. "Start with light weights, two 45’s at first, and gradually increase the weight every set. Start with 8 reps and build up from there. Take a 45 second break after each set."
Dan starts lifting again.
After Dan’s first set Josh laughs and asks, "does working out turn you on or are you just happy to see me?”
Dan chuckles nervously, "I...uh..."
Josh snorts, "Relax man! I'm just messing with ya! I get chubbies working out sometimes too. Not like anyone else is here anyway.”
Dan and Josh continue working out together for the next hour. It’s a good workout and Dan is thankful for the opportunity to get out all his energy and frustration. They say their goodbyes and head out. Dan grabs his gear out of the locker room and heads back to the dorms. He can shower there.
Back at the dorm, Dan showers quickly and climbs into bed. It's only 10 pm But he’s exhausted.
He falls asleep almost immediately.
***
Life, classes, workouts, and routines continue on as normal.
Dan realized the ‘swelling’ he experienced wasn’t swelling at all, and he had been fortunate enough to have a big little growth spurt. He wasn’t going to complain about it though. He was still a little embarrassed of the way it seemed to always stick out so much and he always felt like people noticed. But he was still just on the upper end of average, nothing huge.
Ben had a few opportunities when Dan was asleep to try his little experiment again, but he decided it would be best to give it time so as not to raise any suspicions. From Dan or otherwise.
Eventually, though, Ben gave in to his temptation.
He came back to the rooms one Wednesday since all he had was 2 morning classes. Dan was sprawled out on the bed, clad only in a loose pair of grey boxers. His thick 6 inch mostly-softy making a clear outline against the fabric along his hip. A round bulge visible between his legs where Dan’s big bull balls hung. Ben decided he should try giving Dan’s cock some new instructions.
“Dan, are you awake?”
No response.
“You know, I heard Ashley was saying that you’ve been stuffing your pants with a pair of socks”
Dan is still asleep but finally responds, "No way, it’s not fake. That’s all me down there.”
Ben smiles, I think this is going to work. “Oh yeah? It doesn’t look that big..”
“Yeah it’s plenty big!” Dan shouts sleepily.
“Dude I don’t know, I’m just telling you what I’ve been hearing. How big did you say your boner is?”
“Like 8 inches.”
“8?! You mean…you really are packing around an 8 inch dick?”
Dan nods vigorously. Ben notices Dan’s underwear twitch slightly. Maybe theres a slight change in flaccid size with the half inch he grew erect. Ben gulps, unable to resist these next words..
“Wow, and that’s soft?”
Dan scrunches up his face, then says, "what?"
"Your cock is soft right now. And you said you're over 8 inches."
Dan blushes, "yeah...that's true."
Ben grins devilishly.
> You dan’s flaccid penis begins to expand inside his boxers.
Dan’s penis grows larger and longer, becoming more prominent beneath his thin cotton briefs. The head is pronounced enough you can make out the glans through the fabric. Its length increases rapidly until it reaches at least 8 inches. It stretches the elastic waistband of his shorts, causing a gap between the garment and Dan’s hip bone.
Dan’s penis is porn star big, and he’s not even erect. His flaccid penis is the size of some porn starts erect!
"oh my god” Ben whispers.
The head of Dan's flaccid member peeks out from over his boxers. It looks long and fat, with a pronounced ridge running along its underside. There is also a noticeable bulge forming near the base, which may indicate an extra vein or two under the skin. The head of Dan's shaft is also swollen, and appears quite large. In fact, it could very well rival a porn actor's erection for girthiness.
Ben feels himself getting hard just looking at Dan's growing prick.
As Ben watches, the tip of Dan's flaccid cock expands outward, stretching the elastic material of his boxer shorts further. Eventually, they begin to tear apart, revealing a substantial amount of Dan's engorged flesh underneath. The elastic material has no chance against Dan's expanding meat, and eventually gives way entirely. Now completely naked below the waistline, Dan reveals a truly impressive tool -- easily eight inches in length and perhaps three times thicker than before. Even after such a significant growth spurt, Dan's organ remains flaccid.
