Title: Triangle
Summary/Prompt: Gokudera/Tsuna/Yamamoto love triangle turns to threesome
Pairings: Yamamoto/Gokudera/Tsuna
Warnings: Threesome, sandwiching
Notes: I didn't give myself a lot of time to write this one, so I felt it was a bit rushed... but it already clocked in at three pages on the meme and I loathe posting more than that. v.v' Anyway, this was one of the very first prompts I filled on the page. I actually don't really like writing Yamamoto very much, and seeing as how this was my first prompt with him, I felt that it was really awkward. Oh well, I tired XP.

...

Tsuna sighed as he sat in the same supply closet that he'd been hiding out in for the past few weeks during lunch.

Everything had started when Gokudera had done something stupid a few weeks ago – namely, kissing Tsuna when Yamamoto had turned the corner and saw them. This wouldn't have stirred up much trouble had Gokudera not been secretly dating Yamamoto at the time.

Naturally, this meant Yamamoto and Gokudera had started on a war path and Tsuna was dragged into the middle of it both as their boss and further as the 'other man', which didn't really fit, because Tsuna hadn't had anything to do with it anyway! He wouldn't have returned the kiss if he'd known that they were dating, and he sure as hell wouldn't have even looked at either of them… okay, maybe he would have looked, but he wouldn't have touched.

Sighing, he hung his head and held his chin lightly, wondering why the lunch bell hated him so much and didn't just ring to save him from his utter misery.

Unless he found somewhere to hide during the moment of downtime, the two of them would take to dragging him off so they could shout and hate-love at each other some more. Tsuna was just an excuse to yell, he found.

It really was a pity… he didn't know which of them he wanted, but he would have been perfectly fine trying with either of them. They were both such wonderful people that… and… yeah.

Squaring his shoulders, he figured that the bell was seconds away from ringing and cracked the door open slightly, peering out to see that the coast was clear and bolted.

He attempted to make it back to the classroom in record time, but was stopped by Reborn's voice saying: "He's that way!" and hearing Gokudera's pounding footsteps stomping out after him.

"Shit…" Tsuna muttered, running faster and colliding viciously with a rock-solid body that sent him to the ground. "Ow, owwwww!"

"Hey, Tsuna…" Yamamoto said, his eyes crinkled, but still sad. Tsuna paused in his whimpering to stare at his friend, feeling his heart clench in pain.

"Look, Yamamoto, I didn't mean for—" he stopped as Gokudera wound around the corner and the three of them stood (sat in Tsuna's case) and staring commenced. "Umm… Class is gonna start pretty soon…"

"Pick him up," Gokudera stated, and Tsuna yelped as Yamamoto grabbed onto him and swung him like a potato sack over his shoulder.

"Hey!" he objected as they rounded the corner and slipped back into the closet he'd exited mere moments ago.

"Okay… so… things have been bad," Gokudera started. "I'm sorry for that, Tenth."

"You shouldn't be apologizing to me!" Tsuna objected once Yamamoto put him on solid ground.

"He doesn't need to apologize to me, either… we came to a conclusion a few days ago, but we couldn't find you to talk to you," Yamamoto shrugged.

"Wha—at?" Tsuna gaped, realizing that he'd been hiding for no reason.

"Yeah… we realized that we both like you, Tenth!" Gokudera stated, staring at him keenly like this was going to make everything okay.

"Ummm… okay?" Tsuna stammered, waiting for one of them to actually say something that would make this any less of a screwed up dream.

"We want to include you in our relationship," Yamamoto clarified.

"Hu—uh?" Tsuna stammered even worse, staring at the two of them in blatant confusion.

Gokudera's bright look dimmed slightly and he looked over his shoulder at Yamamoto, who stepped forward and grabbed Tsuna by the front of his shirt.

"Oi!" Tsuna objected, but stopped when Yamamoto pressed dry, but smooth, lips against his. Tsuna gasped and Yamamoto inserted his tongue, kissing him fully and worshipping the inside of his mouth.

Tsuna melted against the kiss, and moaned in disappointment when Yamamoto pulled away, and then chirped in surprise when Gokudera instantly took up his place, grabbing Tsuna's face and holding it solidly against his own. Gokudera's spicy taste of cigarettes and gunpowder filled Tsuna's senses once more and he couldn't help it when he compliantly molded to Gokudera's body and allowed himself to be pushed back.

Gokudera took no time at all in undressing him and Tsuna was far too dazed to make out the words that Yamamoto and Gokudera were whispering back and forth. He almost gained a brain cell when Gokudera stopped kissing him for point five seconds, but lost it again when Yamamoto took over and he felt his pants being removed.

"What's going on?" Tsuna muttered, his brain too fuzzy to object when his legs were spread, but still savvy enough to realize that being naked with his knees wide apart was a very unnatural thing to do.

"Shh…" Yamamoto soothed, kissing him again and gently playing with one of his nipples while Gokudera worked between his legs.

Tsuna grunted slightly at the surprising presence of something against his asshole and he jerked lightly, but quickly fell back when Yamamoto pinched his nipple and distracted him.

He hissed in displeasure, however, when Gokudera inserted a finger into his ass.

"Stop that!" Tsuna mumbled, but was ignored and his back arched lightly when the finger pushed deeper into him, stretching and opening him.

Tsuna flailed a little bit, but was stopped once more by Yamamoto's hands, this time on his half-hard erection that gradually sprung to life under Yamamoto's clever hands.

Tsuna was soon panting and awkward, attempting to get Gokudera to stop while convincing Yamamoto to continue and then just shutting up in general when Gokudera inserted another finger and spread him even wider.

Tsuna bit his lip and tasted a bit of blood, and unconsciously bit even harder when some secret portion of his body was stroked and it sent liquid fire through his bloodstream.

"AH!" Tsuna screamed and his mouth was soon covered again by Yamamoto, who swallowed his cries hungrily.

A third finger was inserted for a few seconds, and Tsuna squirmed under the pressure and odd feeling of it all.

Soon enough, the fingers were removed and shuffling occurred, including Yamamoto moving away from him and Gokudera standing up and moving face-to-face with him.

"Hi," Tsuna said with a dazed smile on his face.

"Tenth…" Gokudera whispered, his eyes wide and looked like he was in awe with whatever he was looking at.

"You look so silly right now," Tsuna said, groaning as he felt something press against his ass again.

"You look breathtaking," Gokudera said, kissing his chin lightly as whatever was pressing against him pressed inside of him.

There was a slight amount of pressure before whatever it was slid past his not-so-virgin-anymore passage and penetrated his body.

Tsuna ground his teeth and felt his back arch a bit in both pain and pleasure, debating which of them was going to end up winning out in the end.

"I know it hurts at first… I'm sorry, it'll get better," Gokudera promised, kissing his cheeks where Tsuna realized he'd been crying.

"Uh… s'… s'okay…" Tsuna writhed, attempting to find a comfortable position.

"You ready?" Yamamoto asked from behind Gokudera and Tsuna frowned when his silver-haired friend nodded and then moaned himself, leaning against Tsuna and panting roughly.

"You feel so fucking good… both of you feel so. Fucking. Amazing!" Gokudera gasped, his hips jerking reflexively and Tsuna's eyes widened when he realized what was going on.

"Oh, wow…" Tsuna gasped, just before Yamamoto pulled back and slammed back into Gokudera, who was sent reeling into his own body and hit something deep within him that made his neck arch and his body shudder reflexively.

Yamamoto kept thrusting evenly until Gokudera started matching his movements and Tsuna wrapped his legs around Yamamoto's back and arms around Gokudera's neck, pulling him down and kissing him breathlessly while Yamamoto fucked them both into the ground – literally.

They didn't last very long in this position, Gokudera coming first and collapsing lifelessly between them.

Yamamoto merely smiled at the middle man's plight and gently lifted him out of Tsuna, who moaned at the loss and then replaced Gokudera's cock with his own, sending Tsuna's head reeling once more.

Yamamoto drove him hard, tightening his body and sending his head through Cloud Nine, until he came with the slightest pressure on his cock and felt Yamamoto's seed enter his body along with Gokudera's.

"Wow…" Tsuna gasped again, eyes fluttering against his cheeks and face flushed with passion.

"Uh huh…" Gokudera agreed from the ground.

"You guys were great!" Yamamoto cheered brightly and Tsuna smiled back while Gokudera just grunted and turned away.

"Felt good," he muttered and Tsuna snorted to himself.

"Understatement," he countered and Gokudera nodded before passing out again and Tsuna made himself comfortable in the circle of Yamamoto's arms.
