I originally posted it on AO3 back in the early part of February. It was a request from burstingkiawe on Tumblr.
It was late Monday afternoon, school was finished for the day, and Izuku invited Tenya over to his apartment for a little study session to prepare for an upcoming mathematics examination in a few days. Inko had to work late that day, but gave Izuku the okay that morning before he left for school. She was glad that Izuku made some great new friends when he started at U.A. high school.
Izuku and Tenya were at the kitchen table with their mathematics assignments. They each had a glass of water and in the center of the table sat a plate of melon and strawberries sliced neatly with some napkins and two pairs of chopsticks. Inko prepared the snack and left it in the fridge for the boys before she left for work.
"Cementoss-sensei really went all out with this study guide," Izuku mumbled and flipped through the pages of the printout packet. A good chunk of the material he understood well enough, but some he missed out on during the lectures because of injuries sustained during Foundational Hero Studies.
"Which section are you having the most trouble with? The stuff you understand the most you wouldn't need to spend as much on. Just brush up on it a little. The harder stuff you should spend the most amount of time on," Tenya said and pushed his glasses up. He held his practice exam packet open.
"Anything to do with graphing. Let's start with that I suppose," Izuku suggested. "I think too hard on some of them and the answer I come up with first is usually right, but doesn't always look right so I keep overanalyzing. I get really mixed up when that happens. Maybe I wouldn't have so much trouble with graphing if I hadn't missed a few classes due to injuries." He chuckled and rubbed the back of his head.
"We can start with graphing then." Tenya flipped to the middle of the packet where the graphing problems started. He completed some already in his spare time. He took out two pencils from his pencil pouch and passed one to Izuku. "Shall we begin? I've got the first page and a half done so you're welcome to work on the first problem in the set and I can check it out."
"Got it," Izuku responded and folded the other pages behind, and looked down at the first problem. Looks fairly simple so far, he thought and went to work on it, writing away the points on the coordinate plane.
Tenya waited patiently while Izuku worked. He picked up a pair of chopsticks that were sitting near the fruit and picked up a piece of green melon and popped it into his mouth. A delightful healthy snack. Its juicy, delicious flavor filled Tenya's taste buds. It had been a while since his family bought that kind of melon. He took a few more pieces.
"Okay… I think I got this one," Izuku said and passed his packet to Tenya.
"Let's take a look," Tenya said as he took the packet and checked over the first problem. "That's correct. Great job, Izuku."
Izuku smiled sheepishly. "Well, that was an easier problem. The others on this page seem to be on a similar level, too." He scanned over the first page, then went to the last page that contained graphing problems. "Oh, the harder ones are here. I guess I should try these ones instead of the easier ones for now."
"Go ahead. We can do it and then compare answers together!" Tenya declared since he wasn't that far yet, but no doubt would get those finished with a breeze. He was one of the smartest in the class after all.
So the two began to work individually on the graphing problem. Tenya was done before Izuku, as expected. With Izuku still working, Tenya went to the answer key to check to make sure he had the correct answer. Everything matched up. He mentally gave himself a pat on the back and waited for Izuku to finish. He leaned back in the kitchen chair and took his glasses off and dusted the frames off against his shirt, then went back to snacking on the melon pieces.
Five minutes must've went by and Izuku was still on that problem. He mumbled away to himself, but Tenya wasn't able to make out what he was saying. "Do you need some help?" Tenya piped up.
"No… I think I'm getting it. I'm almost finished."
Tenya nodded, but then felt a pang in his lower abdomen. He dropped a hand down and rubbed. He bit back a wince as his stomach felt like it bubbled for a moment. Maybe I shouldn't have had so much juice back at home. Poor Tenya had some constipation issues lately due to stress from his brother's retirement and health. He read that prune, apple, and pear juice worked well to combat constipation. Maybe alternating between the three in such a short period of time wasn't actually wise. It definitely was not settling well with all the melon pieces. He hoped that Izuku would finish the math problem soon so he could try going to the bathroom.
But Izuku still frowned and recalculated. He couldn't have missed that many of the math classes! Alright, calm down, Iida. Maybe he hasn't taken that long to work on this problem!
By the time Izuku was finally finished, Iida's stomach hurt like hell. The gurgles, thankfully, were quiet. The only problem was that he needed to fart. He felt the gas waiting for its release, but he couldn't let loose right in the kitchen! Nor did he want to in case it was loud. There was also the slight possibility that he may shit himself if he tried, which was the worst thing that could possibly happen.
"I'm finished with that one," Izuku said and let out a breath. "I think I've gotten the hang of it now. You can check it to be sure." He handed the packet to Iida.
Tenya swallowed thickly and took the packet. He did a good look-over while Izuku munched away on strawberries. Izuku did well aside from a minor calculation error that made the answer come out a few numbers too large, which he pointed out. Izuku corrected the problem when Iida handed it back.
"I'll try out the next two and then we can move on. I can use the other problems as an example," Izuku decided, then went to work again.
Tenya went back to rubbing his stomach just as a small whine vibrated against his hand. He really needed to use the bathroom now. There was no way he'd attempt a fart to get rid of some of the pressure now. Not if he wanted a giant mud missile to kiss his underwear.
Hurry up…hurry up…hurry up. Tenya knew he should've just excused himself. He'd been to Izuku's house enough times to know where the bathroom was anyway. The only thing he knew was that it was going to be a messy dump. A very messy dump. It would be shocking if it was anything less. Probably would take him a little longer to clean himself up afterward, too. Izuku having to wait that long would be embarrassing. Tenya knew he'd come to check on him unless he'd be too focused on the schoolwork.
With his brows furrowed, Izuku picked the packet up and asked, "So I do these like the previous ones?"
Tenya rose from the chair and leaned over the table. Maybe he moved a little too quickly. Maybe he should've clenched his ass cheeks as tightly as he could. Maybe he shouldn't have gotten up in the first place until the urge to shit dimmed down. But he did neither of those options and deeply regretted it. A massively loud and smelly fart erupted from his ass that sent an equally massive amount of shit into his drawers. His pants and underwear felt weighed down by the pile and he looked around frantically, face a deep red shade.
Izuku just stared at him, mouth hanging open, eyes wide until he realized what happened. He blushed as well and looked down at his pencil.
Awkward silence ticked on and on while the two teens searched for something to say. Anything to break the silence. Tenya swallowed hard and quickly moved away from the table and out of the kitchen. He was beyond embarrassed and his face was so hot it felt like it was about to melt off. He shouldn't have eaten that fruit. He shouldn't have had so much juice. So embarrassing!
Izuku trailed behind Tenya, his face tinted red as well. "Tenya…"
Tenya glanced back at him, but continued on down the hallway until he got to the bathroom. Izuku followed him in and closed the door behind them. "Tenya," Izuku said again. "I can wash your pants and underwear for you and give you a pair of underwear to borrow."
"My…underwear is ruined," Tenya muttered and turned away from Izuku. He started undoing his belt.
"You can still borrow a pair of my underwear. Pants, too, for that matter." Izuku bit his lip and wrung his hands. "Accidents happen sometimes. I've had my fair share of embarrassing moments. Believe me." He smiled into the bathroom mirror and saw Tenya looking back.
Tenya unbuttoned his pants and pulled down the zipper and slowly pulled them down. His underwear sagged in the back and the smell got worse once his pants were down. Izuku ignored it and watched. Some shit streaked underneath one of the leg cutouts of Tenya's underwear. Izuku moved closer until his fingers wrapped around the waistband of the underwear. "Here…let me help."
Tenya's eyes widened and he waved his arms. "No, no! I can do it myself, Izu—"
But Izuku pulled the underwear down anyway. Tenya miraculously jumped out of both the underwear and pants as the former hit the ground with a messy slap. Tenya's feces looked like a messy mud pie. "It's not like I haven't seen you naked before. We had sex just yesterday."
"Hush up, will you?! Now's not the time to think about that!" Tenya's face was so red.
"Just let me help you with this, okay?" Izuku asked and put his hands on Tenya's chest. "It's the least I can do for you."
"I'm perfectly capable of cleaning myself up—"
But Izuku closed his eyes and muffled Tenya with an interrupting kiss to keep him quiet for a few moments at least and to stop him from freaking out too much over shitting his pants. Tenya pulled back, eyes slightly wide. He rubbed the back of his neck. "I don't think now is the time for this," Tenya mumbled.
"I want to distract you and I also want to…try something out. Something I've wanted to try for a little while now. If you're up to it, that is," Izuku said.
"I'm too dirty and smell bad."
Izuku grabbed his hands and gave them a squeeze for a moment. "I don't care about the smell or dirt. Come on. Let's have sex."
Tenya gasped. "What?! Are you serious?! That's so unsanitary with the condition I'm in now!"
"I don't care, Tenya. I want to try this. Please. I've…I've had a fantasy of a fetish like this for a few years and now is the perfect opportunity to try it out, but if you don't want to try it out that's fine, too." Izuku wrung his hands and offered up a small smile. He knew his scat fetish wasn't for everyone and there were probably many who weren't into that. Tenya definitely didn't seem to be someone who would be into anything like that. To someone who didn't know Tenya well like Izuku, some might have thought the teen was a prude stickler with a massive stick up his ass.
"Izuku, you will be putting yourself at risk for a bad urinary tract infection if you don't clean yourself properly afterward." Why does it sound like I want this?! It's kind of strange, but Izuku is so tempting. Maybe it wouldn't be that bad…
"I know." Izuku furrowed his brows in understanding. "I know the risks of that and the general risk of anal sex. Every time we've had sex where I topped I always cleaned myself. You know that. Just trust me, Tenya."
Tenya bit his lip and rubbed the back of his neck again. "A-Alright." He took a deep breath. "Alright," he said again more confidently and determined.
Izuku's eyes practically lit up. "Then lay down."
Tenya nodded and took another deep breath before he laid down on the tiled floor. It was quite cold against his bare ass and sent goosebumps across his body. The tiles were no doubt going to be streaked with his shit when he got up. He watched as Izuku undressed quickly. They had plenty of time to enjoy themselves before Inko got home, but Izuku was an eager beaver.
Once his erection—that Tenya never even noticed he had—was freed, he moved between Tenya's legs and gave his cock a pat. It was half hard and growing. Izuku smirked. Maybe Tenya was kinkier than he thought. "Are you fine with not using lube?" Izuku asked, eyebrows raised.
"Y-Yeah. Just go ahead when you're ready."
Izuku nodded and rubbed the head of his cock against Tenya's messy entrance. Poop smeared against the head. He teased Tenya for a few moments. He knew how much it drove him wild. He could already hear Tenya's teeth gritting together in pleasure-filled annoyance. Izuku chuckled and pushed inside Tenya. The shit made his hole kind of slick in a dirty sort of way. It was surprising.
Tenya groaned and tilted his head back into the cool tiles. His body heated up from embarrassment and pleasure. Being fucked by your boyfriend after you shit yourself and didn't get a chance to clean up was definitely something he never thought would happen. Ever. Yet here he was getting dicked down with a shitty asshole by his boyfriend.
When Izuku started thrusting, Tenya nearly saw stars. It was his first time going dry…well, without lube. He wasn't exactly dry.
Izuku heard the sounds his cock made with each snap of his hips. It was a different sort of sound…like a mushy sound rather than some type of squelching. Mush was the exact consistency of Tenya's feces—a dark brown that looked like mud or disgusting chocolate pudding. Tenya was just thankful it wasn't full blown diarrhea. It would've been explosive if that was the case.
The teens were a panting mess, their faces flushed. "F-Fuck, Izuku." When it came to sex, Tenya sometimes had a sailor's mouth. Izuku as well. Neither one was swearers, but when it came to sex, that changed everything.
"You like it, Tenya?" Izuku asked between breaths. A small smirk was on his face. The bathroom smelled like a barn the longer the two went at it. Tenya's crap smelled like it was starting to ferment on the bathroom floor. They were going to have one heck of a mess to clean up once they were done.
Tenya's nod was barely there, but Izuku caught it and grinned. Though so, Izuku beamed.
Their sounds filled the bathroom and they quickly approached their climaxes. Tenya shuddered as he came, moaning Izuku's name. Izuku gasped as he spilled his seed deep inside Tenya. He gave a few lazy thrusts before he pulled out and collapsed beside him on the floor. "That…That was amazing," Izuku breathed.
Tenya nodded, eyes squeezed shut and glasses disheveled. He swallowed. "Y-Yeah…"
Izuku looked at the mess on his cock and blushed. He'd have to get to cleaning that up right away, but it was well worth it. "I guess we should have study sessions more often, eh?"
"Minus defecating in my pants," Tenya muttered, but had a tiny smile on his face.
Izuku laughed as he got up on uneasy legs to prepare to clean up from their new sex adventure.
Nice comments are appreciated.
