Justin woke up in the morning, feeling groggy and bloated from last night. He could feel his dick rock hard and throbbing and a wet spot of precum on his sheets rubbing against him. After a minute or two of dickstraction passed over him, he settled down and let the memories of last night rush in.
A guy he had chatted with online came over. He was a “feeder,” which I guess means a pervert who gets off on stuffing guys with food before sex. Not really Justin’s thing, but the guy was hot and it had been three weeks since he’d been fucked. This guy, Alex, arrived with a shoulder bag full of food in tow and Justin was a little surprised. Alex had been clear about his plan to stuff him until a belt popped out over Justin’s well-toned midriff, but honestly Justin assumed it was a silly fantasy and they’d skip straight to sex when they met. But Justin was pretty game for kinky stuff and he hadn’t eaten dinner yet, so he didn’t mind a few calories before he felt Alex inside him.
Alex sat down on the couch and Justin started with some small talk. Alex answered in short, curt responses that felt intense rather than rude. After a few minutes, Alex interrupted Justin mid-sentence:
“I don’t really want to chit-chat. Do you want to see what’s in my bag?”
Justin was taken aback but still felt drawn in by Alex’s directness. Justin was a very submissive bottom, even though in real life he was confident and assured. Normally assuming a “sub” role in sex felt performative but he’d been with a handful of truly dominant men where it came naturally. This night was starting to feel that way and Justin got a bit flushed and excited. He nodded his head.
Alex pulled out a few snack foods and set them on the coffee table — donuts, cookies, a foil-wrapped slice of cake. And then he set down a thermos next to it.
“What’s in that? Milk to wash everything down?”
“No, I don’t think you’re ready for that. I brought it just in case.”
Justin chuckled a little. “What?! What could it possibly be that I wouldn’t be ready for?”
“That is a very special drink. When you drink it… something happens to you. It gives you a ball belly almost immediately and adds on 10 or 20 pounds. It’s kind of like magic for gainers. The guy I bought it from told me it rewires your brain, too, makes you want to get huge.”
“I know, you don’t believe me, boy,” Alex continued. “I didn’t either, I’d never heard of this stuff before. But my roommate poured himself a glass the other day and I saw the results for myself. Serves him right for taking my things from the fridge. He doesn’t seem to mind the weight gain though, he looks like he’s growing more every day.”
What a weird game to play. Justin was pro-kink but not very good with imaginary roleplay and honestly all this talk was starting to ruin his sex drive a little. He stood up and offered Alex a glass of water to try to shift the conversation away from a dumb story.
“Sure, lots of ice. You should get yourself a glass too, to wash down the donuts.”
“I’ll probably just wash them down with the thermos,” Justin playfully retorted with a wink.
“You’re not really into this gaining and feeding stuff, are you? I could tell you were just playing along with me online, which is fine, but guys usually perk up a bit in person and get into it.”
“No, no, it’s not that. I’m absolutely down to have to feed me some food before sex. I just don’t have a great imagination for stuff like the thermos story so I’m not sure how to play along.”
“It isn’t make-believe, I’m telling you the truth. I brought it with me because you never know if a guy really wants to kickstart his gaining journey, but I’ll just put it away so we can focus on this junk food instead.”
Justin returned with the waters and asked him to leave the thermos out, still not believing him but wanting to look on board for the game. Alex left the thermos on the coffee table but pushed it to the side, and he opened up the box with six donuts. “We’ll start with these.”
Justin started unbuttoning his short-sleeve dress shirt, but Alex stopped him. “No, you should leave this on boy. I want to see it get tighter on you as you finish this entire box.”
Six donuts doesn’t seem like a lot for a sexy binge-eating game, but by the third donut Justin was starting to feel uncomfortable. It wasn’t really the calories, it was the sweetness of them and the speed that Alex was pushing them into his mouth. He told Alex that he needed a water break and that he wished he had brought something savory in his bag instead of so much sugar. But Justin was no quitter and powered through the fourth and fifth donut.
The entire time Justin was eating, Alex was hand-feeding him. He used his other hand to rub underneath Justin’s shirt and moan into Justin’s ear. Alex was clearly very into this and, even though Justin was feeling what he was also getting aroused by Alex. He looked down and saw the unmistakable outline of his hard bulge against his 4-inch inseam shorts. He knew Alex was hard too because he’d been feeling him over his jeans while he ate. Alex paused to have a drink of water and Justin reached for the thermos that was still on the coffee table.
“What are you doing, boy? You know you don’t want what’s in that.”
“Maybe I do, Sir. Would you let me drink it if I wanted!”
“I bought it for a reason, so yeah I would. But you work hard for your body, I don’t think you want to lose it quite yet. Although given how you’re taking this feeding, maybe there’s a gainer deep down in you after all.”
Something takes over Justin when he gets horny enough. He’s a pleaser. He’s let guys choke him a little too hard and slap his ass a little too firmly because in the heat of the moment he begs them to do it. He wanted to drink the thermos. He wanted to drink it so badly, even though Alex’s story was bullshit, because he knew it would turn Alex on. He picked up the thermos and unscrewed the lid. It was heavier than he expected. The liquid inside looked thick and smelled like vanilla. He held back a laugh as he realized: it was a milkshake. He took a small sip and set it back down.
Alex looked shocked but a grin started to take over his face. “You don’t know what you just did, boy.”
Justin smiled. The thermos tasted incredible. It wasn’t a milkshake like he assumed, but it tasted similar. It was thick, almost like pudding, but it went down his throat so smoothly. He could tell Alex was pleased. He leaned in to kiss him but Alex stopped him. “Just wait a minute. Let yourself enjoy what you just drank,” and Alex placed Justin’s hand on his own stomach.
It was puffy! Justin was no stranger to feeling a little bloated from a big dinner, but this felt a little more pronounced than that. Softer. “I guess that’s what five donuts will do to a guy,” he laughed.
“Not the donuts. I could barely feel this when you ate them. This is just from the thermos,” Alex replied. “It was just a tiny sip that you took, so I’m sure if you stop now that’ll be the only effect.”
Justin played along and reached for the thermos again, downing three or four big gulps this time with his free hand still on his stomach. As soon as he swallowed, he felt his stomach noticeably expand and his shirt tighten around him. (“what the fuck?”) His mind raced (“what the fuck??!”) and he stood up quickly. “What the fuck?” he said, this time out loud.
Alex relaxed back into the couch. “You really didn’t believe me? I thought you did after that sip. I don’t think you’ll want to stop now.”
“I’m done with this game, what the fuck was that? It’s going to take me a week to get rid of whatever this is.”
“Just give it a minute. Sit down. Relax a bit, everything is just fine.” Justin’s mind was still going a million miles an hour but something about Alex was so comforting to him. He sat down next to him and leaned into him, placing his head on his chest as Alex leaned back and held him. They spent the next few minutes in silence before Justin asked why Alex was so into “feeding or gaining or whatever.” Alex explained that fat guys are hot and making guys fat was even hotter: the sense of control over them, the transformation and shock and denial boys felt. He told Justin about the first guy he introduced to gaining and how hot it was that he kept coming back to Alex for more.
While Alex went on about this guy he made fat, Justin started to get hard again. He rubbed Alex’s chest under his shirt and noticed himself relaxing the stomach he had been trying to suck in. He looked down and saw a small roll of belly overhang that wasn’t there before, but seeing it now felt kind of hot. He reached down and touched his belly gently and started rubbing. He didn’t look up at Alex, but if he had he would’ve noticed Alex had stopped speaking and started smiling. Alex watched as Justin felt and then played with his belly with less and less self-consciousness as both of them felt their dicks get harder.
Alex finally broke the silence. “You want some more from the thermos now?” Justin snapped out of the trance his small-but-noticeably belly had on him and looked up at Alex with questioning eyes.”
“Well if you aren’t sure, you don’t have to. I should probably get going anyway, no worries at all. This has been a lot of fun.”
“No, wait! Fuck Sir I think I do want some more.”
“Yeah? Good boy,” Alex said as he leaned forward and grabbed the thermos. “How much do you want? There’s not much left, honestly,” he said as he swirled around the contents. They could not tell there was a lot left, at least 32 ounces.
“You’re right, Sir,” Justin played along. “I could try to finish it.”
Alex held the thermos to Justin’s lips and held his other hand to the back of Justin’s head. Justin opened his lips and tilted his head back as the contents of the thermos poured into him. It felt sweet as it touched his lips but not sickly sweet. It flowed smoothly down his throat and Justin swallowed gulp after gulp. It was incredible, he didn’t want to stop as he felt more if it inside of him. Alex guided his head back further and the thermos up further until it was empty. He gently pushed Justin’s head up and set the thermos down.
Justin felt total bliss. The buttons on his shirt strained and then popped all at once, exposing his hairy growing chest. His shorts got tighter and he rushed to unbutton and unzip them. He heard the waistband of his cotton briefs tear and when as he stood up they fell around his ankles. He was standing in front of Alex, naked, as his body grew. His stomach went from puffy to a full, round belly that continued to expand. His toned pecs softened and looked puffy as they rested on his gut. His arms thickened. His thighs doubled in size. His erect penis lost a full inch under the fat bad that puffed under his belly.
Justin looked over at Alex, who was stroking his dick and teasing him. “Look at you! Big fuckin’ boy, I had no idea it would work this well, fuuuuuuuccckkkkkk.” He stood up and lead Justin to the bedroom, enormous ass up, and fucked him hard. His cock was so wet with precum that it almost slipped into Justin and the extra cushion from his soft ass pushed against him as he pushed in and pulled out. They were both so worked up that Alex only lasted a few minutes before exploding inside him. Justin felt the warm hot jizz and he came hands-free all over his sheets.
Alex cuddled into Justin’s soft torso for a while before telling him he had to get going. “Tomorrow you’re going to wake up and still be this big. Send me a close-up video of that fat belly first thing when you wake up. We’ll do this again very soon.”
Justin looked down and saw his huge belly while the morning sun shined through his window. He felt fucking great. He stood up and wiped the sleep from his eyes and noticed Alex had left his underwear behind. Alex was a bigger guy than Justin — well, I suppose that wasn’t true anymore, but his underwear was larger than anything Justin owned. He slipped on the briefs and set up his phone to take a video for Alex. He slapped and rubbed his fat belly and it looked huge on his phone. He loved squeezing and rubbing his new body, it felt so natural to him.
He sent the video to Alex as he was told, along with one pleading line:
“Round two tonight, Sir?”
