Thong Song

Summary:

Suguru has been hiding his feelings for his best friend for a long time. Satoru is wearing a thong.

Notes:

Work Text:

Suguru pushed open the front door, his body was sore and he was exhausted. This had been one of the worst missions he had been on recently. It was just disgusting, he was so done swallowing this shit and just going on these repetitive missions. But really he was just tired, it was all the way down in his bones. Not to mention that his roommate, the love of his life, wasn’t at all on the same page about how he felt and seemed content in torturing him. Said roommate was currently sprawled across their couch.

Suguru’s mouth went dry, “You’re wearing my shirt.” It really shouldn’t be a big deal, Satoru borrowed his clothes all the time. He liked them because they were bigger. But he was absolutely swimming in this. He also wasn’t wearing pants, and even though Suguru knew he had something on underneath he couldn’t help but imagine Satoru being naked in just his shirt.

Satoru chuckled, “And your shorts. C’mon you said it would be okay. Plus they’re more comfortable than mine,” he leaned back on the couch. “Plus you were gone for a long time. I was starting to miss you and I didn’t want to do laundry, you know I hate wearing dirty clothes.”

Suguru put his head in his hands, this was too much. Fuck he forgot how tiny Satoru was, or of course he didn’t forget how tiny he was but actually seeing it. He was swimming in his t-shirt and he knew his shorts were barely holding on to Satoru’s hips. He couldn’t handle this right now.

“You look tense Suguru. Was your mission hard?” Satoru patted the cushion next to him inviting Suguru to sit down. Suguru went easily, he wasn’t one to deny his best friend. Satoru made a pleased sound and scooted up next to him.

“Honestly, it was pretty bad.” There was his reality check, nothing kills the mood quicker than thiking about swallowing those fucking cureses. “It just gets grosser and grosser every time I have to swallow one of those damn things,” he wanted to gag just thinking about it. He hadn’t really talked to Satoru about it, it felt stupid complaining about something so small when he was literally talking to the strongest jujutsu sorcerer. Gojo had to deal with so much shit, he was always expected to do this, it was the life that he was born into but also the life he was destined to lead, so talking about how he hated it always felt like the wrong thing to do.

“Suguru…’’ Gojo took a deep breath trying to steal himself. “You can stop, you know,” a guilty look crossed his face. “I know you feel like you have to because you’re special grade, but seriously you don’t. Or maybe we can just do the big stuff. Other people will do those missions, people like Nanami and Utahime,” he laughed. “Just come teach with me and when things get really bad we’ll help but teaching is fun. And seriously it’s like you’re meant for it. You won't have to go on these nasty missions and I can see you everyday.” Gojo blushed. “Sorry that was a lot.”

Suguru laughed bitterly, “Satoru, you know what I did, what I wanted to do, you know what I would have done if you hadn’t stopped me and talked to me that day. I was going to cleanse the world of humans like some crazy fucking dictator, I was going to murder everyone in that town,” he huffed. “How could I ever teach, how could I ever put myself in a position to help young people when I’m so horrible.” He didn’t mean to, it wasn’t on purpose, but he felt tears slipping down his cheeks. They didn’t talk about that either, how he almost went down that path, how Satoru literally had to drag him back from the brink. He was going to kill his fucking parents for God’s sake. He put his head down in shame, he couldn’t forget who he was.

He felt fingers firmly grip his chin. “Don’t,” Satoru’s eyes were boring into his, they were gleaming and Suguru realized that he was mad. “You were a kid, you saw something fucking horrible. I was there too Suguru, you had to stop me from murdering all of those star religious freaks. You didn’t act on it, you talked to me and now we're okay. You have to forgive yourself,” Satoru took a deep breath, he looked close to tears himself. “You have to move on. And you can help the kids that have the same feelings you did, the same fear you did.” It’s one of the most serious conversations they’ve ever had, he couldn’t believe that not even ten minutes ago he couldn’t get his brain out of the gutter.

“You know, for someone so dumb you sure are insightful,” he chuckled. “I think I’ll talk to Yaga about it,” he blushed. “Thank you Satoru, you’ve never given up on me.”

Satoru giggled, trying to regain their light mood from earlier. “Let’s watch a movie, I’m gonna make some pop-corn.”

“Yeah, I still need to shower.”

“Ah, a shower sounds nice, it’s been a few days.. I haven’t done laundry, can I wear something of yours?”

“You know you don’t have to ask.”

“Thanks. And Suguru…” he trailed off and waited for Suguru to look at him. “I’m never going to give up on you.”

Suguru was out of the shower first, Satoru tended to run up the water bill, but he honestly didn’t mind. He was making the popcorn when Satoru rounded the corner. He choked on nothing, literally nothing. He knew he had said that Satoru could borrow his clothes but for some reason this was so much worse than he thought. He usually had to compose himself when Satoru wore his hoodies or his pants but this was ridiculous.

Satoru was wearing his training sweats, that Suguru liked to wear a little loose so of course Satoru was just fucking swimming in them. They were hanging so low on his hips he wasn’t even really sure how they were staying on. And he was wearing this massive t-shirt that Suguru had cropped and cut the arms off of, so whenever Satoru even so much as turned Suguru got a full view of his pretty pink nipples.

He was trying not to get hard. God he was a degenerate, the clothes weren’t even especially slutty, it was just the way that Satoru wore them. Seeing him in his clothes after everything they had just talked about, it was almost too much. He had to purposefully direct his gaze back to what he was doing. He wasn’t a pervert and he wasn’t going to ogle his best friend just because he was the most gorgeous person to ever walk the Earth.

“I love your clothes, they’re so flowy.” Suguru couldn’t move, he watched as Satoru opened the fridge and reached down for a soda. His brain short circuited, what the fuck was he wearing? Why did he even have that, there's no way it was comfortable.

Satoru was wearing a fucking thong. It clearly had a thick band, but still it was a fucking thong, and it was peaking out from above HIS sweats. Fuck this was not good. He wanted to rip the sweats off of him and see what was underneath. Was that his preferred underwear, it didn’t seem right, like he could fight or even teach in that.

His voice came out horse, “Are you wearing a fucking thong?” His hands were shaking and he looked half insane but for some reason he wanted to hear Satoru say it. Apparently his brain to mouth filter had stopped working too, but for some reason he couldn’t take it back.

Satoru’s cheeks pinked a little as he looked up. “I mean yeah, they’re comfortable and I guess I like how they make my ass look.” He hooked his thumb in the strap and popped it. “They’re cute too, honestly I only wear them at home. God can you imagine if ….”

But Suguru couldn’t hear him over the blood rushing from his face to his dick. He stumbled closer to Satoru, apparently not in control of his own faculties and reached for the strap like Satoru had done, he pulled the band and popped it against Satoru’s tiny tiny waist.

Realizing what he did he quickly said, “Fuck, sorry. I don’t know what the fuck I’m doing.” He looked at Satoru who looked just as bewildered and decidedly more red, there was something in his eyes too, something crazy that he only ever saw when he took on a qualified opponent.

Satoru looked at him for a second, “Do you want to see them?”

Suguru had to let his brain catch up, “Do I want to see your underwear?”

Satoru nodded earnestly, “Yeah, do you want to see them? They’re comfortable and they fit nice. It seemed to me like you were interested in seeing them,” all of his blushing bashfulness was gone now. Suguru could feel his mouth filling up with saliva, he knew he should say no, that this was some weird test Gojo was making him do, but he did. He really wanted to see them and if Satoru made fun of him or called him gay it would still be worth it. The more he thought about it the more he needed it.

His throat was dry, “Yeah. I want to see them.” He felt his cheeks flush and knew he probably looked insane but he wasn’t going back on it, not unless Satoru did.

“Okay Suguru, pay attention,” Satoru said as he lowered the sweats, he made a show of pulling them down slowly but once they were passed the swell of his ass there was nothing for them to hold on to. His mouth went dry, these were clearly underwear made for men. There was a pocket big enough to hold Satoru.

Suguru was working on autopilot now, “You said they make your ass look good.” He reached over and forcefully turned Satoru around so his front was pressed into the counter, he backed up to look at him. “Fuck,” his voice came out gruff. The underwear might have fit in the front but Satoru’s ass was not covered at all. The thick band disappeared between his two perfect cheeks.

He couldn’t help himself, he would stop but only if Satoru told him to. He dropped to his knees behind Satoru and grabbed his ass. Satoru let out a muffled gasp. Hands full Suguru started to massage Satoru’s ass. Fuck he wanted to bite it, leave a mark, mark up his thighs too. What was stopping him? He gently pressed his teeth into the swell of his ass and bit down.

“Oh my god,” a punched out garbled sound came out of Satoru. He started sucking a mark into his cheek. He was going to mark him everywhere, everyone would know who Satoru Gojo belonged to.

Leaving a fat mark he moved to a new spot, Satoru had started softly mewling, and for some reason that really pissed Suguru off. He pulled away from what he was doing and said, “Don’t try to be quiet, I want to hear it,” he bit down hard.

“Ah..,”Gojo let out a choked noise, clearly surprised. He was still trying to be quiet, and Suguru realized that he had planned this. He dressed that way to torture him, why did he only wear his slut underwear at home? How long had Satoru flaunted his perfect tight body in front of him. No, Satoru was his now and he wasn’t going to be teased. He was done playing his game and now he was going to take what was his.

All the nerves he had felt before withered away the second he saw Satoru’s ass and he wasn’t about to find sense now. Clearly they both wanted this. His fingers moved to spread his cheeks. Gojo let out a loud breath, “Suguru, what exactly do you think you’re doing.” Suguru was not going to respond. He pulled the fabric from between his ass cheeks and moved it to the side before Satoru could say another word he leaned in and flattened his tongue over Satoru’s entrance. Satoru’s knuckles went white where they were gripping the counter.

“Nghh,” apparently Satoru was having a hard time talking too. Suguru slowly worked him up, starting by gently kissing his hole and licking over it. When it seemed like Satoru was finally starting to relax he gently prodded with his tongue until he could slip through. Slowly he started fucking him with his tongue.

“Ahh,” Suguru could see slow tears rolling down Satoru’s face. “It’s too much, fuck I can’t.” Satoru’s legs went limp, Suguru’s strong hands on his waist kept him upright. This of course just made Suguru go deeper. Satoru whimpered and his body started to struggle and for some reason Suguru fucking loved it. “Suguru you have to stop, if you don’t I'll…” Suguru reached around and palmed Satoru through the flimsy material of this thong. He ripped it down and wrapped his hand around him. Satoru gasped and came to the counter.

Suguru stood up behind Satoru and dropped his head down to rest on his friend's shoulder, “You’ve been wearing that shit on purpose. Trying to get a reaction out of me,” he groaned as he pushed his clothed cock into Satoru’s back side. Satoru whimpered. “You’re so fucking sensitive too, fuck.” Suguru looked over his friend's shoulders and saw the drying tear tracks down his face. He knew he should be concerned, worried that he had done too much or gone too fast, but seeing Satoru flushed from crying with his watery eyes made heat travel through his body. He couldn’t help it; he grinded into him again, wrapping his hands around Sataru’s waist.

“Look at how fucking tiny you are,” his hands practically touched where they wrapped around Satoru’s waist. Before Satoru could even start to respond Suguru dropped his mouth down to his neck and bit down hard. He had always wanted to mark up Satoru, had thought about it late at night, or when Satoru wore those short fucking shorts he seemed to have an endless supply of.
He could hear Satoru whining, mumbling incoherent words. He popped his mouth off of him and said, “I want to fucking break you, ruin you for anyone else who ever thinks they can touch you.”

“Suguru, please,” Satoru let out a long moan. “Please, please I need you.” Suguru groaned, pushing himself into Satoru over and over again.
“You want me to fuck you,” he breathed against his neck. “Fuck you here when you’re all lose and wet,” he licked a long stripe down Satoru’s neck.

Satoru nodded, “Fuck, please Suguru. I can take it.”

Suguru let out a choked laugh, “Fuck, I planned to do this differently.” He was already reaching down for the waistband of his pants. “I wanted to lay you out and worship you. Talk you through it.” Suguru pulled his cock out and pressed his head against Satoru’s entrance. He was still wet and messy, he knew it would be a stretch but Satoru could take it. He spit on his cock and rubbed it in.

“It’s gonna hurt Satoru.” He tugged on his earlobe with his teeth. “You’ve never done this before, right?” He watched Satoru’s neck flush red. Oh, he liked that.

Satoru nodded. “Only you Suguru, you know that.” And Suguru did. He felt it low in his stomach, rising to the top. The heat and love he had always felt for his best friend. They were destined, they were each other's balance, and now he was going to stake his claim. “I don’t care if it hurts, I want it. Now.”

That was all Suguru needed to hear. “Only you Satoru,” was all he said before he started to push in. He felt Satoru tense up immediately, it was a big stretch, he hadnt taken any fingers, and he had never been fucked. It was so fucking tight, everything Suguru had ever thought it would be. He was hot and tight and whimpering like he fucking liked it. Suguru knew he would, knew that Satoru was kind of fucked up too and that he would like it to hurt the same way Suguru did.

Suguru knew what would help Satoru, he reached for his chin and pulled his face to the side. What he saw was almost enough to send him over the edge. Satoru’s face was blotchy and red, he was panting hard trying to keep himself from crying, he looked like he was lost. Suguru wanted to push harder, make him cry, but he reminded himself that if he was going to take Satoru’s virginity on the kitchen counter the least he could do was keep his cool for a little longer.

“You’re so beautiful baby,” he whispered, ghosting over Satoru’s lips. “Such a good boy, taking it so well,” he punctuated his last words with a small thrust and watched Satoru’s eyes go hazy. Slowly so as not to startle him, Suguru leaned the rest of the way in and brushed his lips over Satoru’s. Satoru instantly pushed his mouth into Suguru’s, reaching his hand up and holding onto Suguru’s jaw. Satoru whimpered as Suguru gently prodded at his lip with his tongue. Heat exploded through Suguru, this was perfect, Satoru was perfect and he was going to spend the rest of his life showing that to him.

Slowly he started to move, shallowly dragging himself in and out of Satoru’s tight wet heat. He knew he was teasing him, but he enjoyed kissing Sataru, and enjoyed winding him up. He reached around Satoru’s waist and slowly started running his fingers over his aching cock, he could feel Satoru leaking. Suguru pulled away panting wetly, “Look at you baby, so wet for me.” Satoru dropped his head down and let out a long moan.

“Fuck Suguru, you can’t talk to me like that,” he was so red. Suguru chuckled and ran his tongue over his neck, still thrusting slowly, still winding him up.

“Talk to you how baby?” he laughed. “You don’t want me to tell you how good you’re doing, tell you how hot and tight you are?” He could see that Satoru was close to breaking. He stroked his hand up and down his cock. Satoru dropped his head down, gripped the counter once again with white knuckles.

“Nghh,” Satoru panted. “Fuck Suguru, stop playing with me. I fucking need it. Please I’ll do anything you fucking want, just fuck me.”

“Hmm,” Suguru hummed. “Anything I want? I’m pretty sure I have everything I’ve ever wanted right now. He slipped his cock head in and out of Satoru teasing his rim and ran this thumb in slow lazy circles over Satoru’s cock head. Since he had initially pushed in he had really only been giving Satoru the first few inches of himself and he could tell it was driving Satoru crazy.

Without warning Satoru speared himself back onto Suguru. Satoru let out a loud cry, his knuckles white and shaking on the counter. Satoru tensed up tightening around Suguru, and Suguru realized how close he was to breaking too. He brought his hand up to the back of Satoru’s neck and pushed him down onto the counter, then he brought both his hands with a bruising grip to Satoru’s hips.

“Fine,” was all he could manage before he started fucking into Satoru roughly. “So fucking tight and pretty. Look at you spread out for me like that. Ass up taking it like a whore.” Suguru knew he was spilling depravity, had never really thought of himself as a person who would enjoy dirty talk. But what it did to Satoru was all he needed to let the words keep spilling from his lips. Satoru was red and panting making these beautiful keening noises every time Suguru said something dirty. Not to mention the pornographic fucking moans that he let slip every time Suguru shoved himself in.

“Can’t believe you would wear those fucking underwear, what if someone saw?” Suguru lifted Sataru’s hips to get the angle right. “Would you have let them fuck you too? What if Nanami saw, what if fucking Yaga saw? You’re such a dirty fucking slut Satoru.”

“Ahh-h,” Satoru was clearly trying to comprehend what was being said, trying to respond. But every time Suguru said something fucked up like that his cock smeared through the cum and precum on the linolium counter. “Wouldn’t, ahh..” he trailed off after a particularly hard thrust. “Already told you. Only you Suguru.” Suguru knew this of course, but he liked making Suguru feel dirty, liked making him feel good.

More tears started to prick Satoru’s eyes, “I-I’m getting really close Suguru.” Satoru was a sight, his back arched and his blissed out expression.

“Fuck baby, me too.” Suguru dropped his weight over Satoru’s back, panting into the back of his neck as his thrust became uneven and rushed. He reached around Satoru and grabbed his cock. Satoru let out a choked off moan before he clamped down on Suguru’s cock and came for a second time that night all over the counter. Suguru groaned as he buried himself to the hilt and came deep inside of his best friend.

Suguru gathered Satoru into his arms and pressed a gentle kiss to his forehead. “You did so good, baby.” Satoru whined and curled into his chest.

“Mmm, I’m sleepy Suguru,” he rubbed his face into Suguru’s pecs.

“Let’s go to bed baby.” Suguru carried Satoru into his own bedroom and placed him gently on the sheets. “Be right back.”

Suguru walked into their bathroom to get a warm towel, he knew he probably should feel ashamed for how he took Satoru. But just thinking about it sent a rush of heat through him. Everything between them had always been so intense, he didn’t want to pretend like they should have had a different beginning. For God’s sake what was he supposed to do Satoru had been walking around in a fucking thong. He made his way back to the bedroom and slowly wiped down Satoru’s belly and ass.

“Here baby,” he handed over an ibuprofen and a bottle of water. Satoru waved him off. Suguru gently grabbed his chin and made him look at him. “Open,” eyes glassy Satoru opened his mouth and let Suguru place the pill on his tongue. Suguru brought the bottle to Satoru’s lips, “Drink.” He didn’t fully understand why it felt so good to have Satoru listen to him without question, but he knew he liked taking care of him.

Suguru climbed into bed next to Satoru and gently cradled him. Satoru mumbled happily and started to drift off to sleep.

“Love you Suguru.”
Suguru’s heart skipped a beat, “Love you too Satoru.”
