Mostly the canon group.

A/N: Well...no suggestions, so I'm just going to slightly alter the canon tournament. Shinso will be the only changed participant, as Tsuyu had to replace someone, and while I love Shinso, he's not one of the ones I want Deku to interact with more or learn more about just yet. I'll also be rearranging the order a bit.

Round 1:
Midoriya vs Mei
Shiozaki vs Kaminari
Iida vs Tsuyu
Mina Vs Aoyama
Momo vs Tokoyami
Ochaco vs Bakugo
Tetsutetsu vs Kirishima
Todoroki vs Sero

Deku talked to Ochaco and Tsuyu before the first round, and agreed that both would fight using their own quirks for now. They weren't ready to reveal their...unique status so publicly just yet, and they also wanted to know how far they could go under their own power...it was one thing to use the borrowed power when lives were at stake, but another for a competition, and so early in their educational careers.

Hatsume approached Deku before their match was due to start and tried to convince her to use some extra support items in their match, to even things out and make things more interesting, since she had so many, but having actually applied for an exception herself, Deku was well aware of the rules regarding support items, and politely turned her down.

Mei seemed to be treating their ongoing fight as an advertising campaign, which made sense...that's why she'd really wanted her decked out with more support items.

Deku was willing to play along, to a point, but she wasn't going to make it too easy.

Mei had some kind of mechanical poles that let her dodge attacks rapidly, and it made it pretty hard to catch her, but Deku caught on quickly that she could have targeted the pole itself if she needed to. so that was a fallback plan.

Deku mostly kept to Frog and her own quirk, keeping mobile and trying to catch Mei off guard and toss her out of bounds.

The back and forth went on for a while, with Deku taking the time to show off her multiple quirks a little, and Mei showing off a variety of new support items.

Eventually, though, Mei finished her ad campaign and surrendered the fight on her own.

Deku headed off to the breakroom for a short rest, but was interrupted from her attempt at rest by the sudden appearance of her former opponent and previous teammate.

"You were playing along weren't you?" Hatsume questioned, grinning.

"Oh uh..." Deku hesitated. "Kindof...I figured out what you were doing pretty quickly."

"I thought so! Thank you for letting me show my babies!" Hatsume leaned in close. "I think you deserve a reward."

She knelt down in front of Deku and began unzipping her costume.

"H-hatsume-chan wait...t-this is just...my pheromones...You've been around me too long today..." Deku stammered out.

"Yeah...Tomoko said something about that..." She put a hand to her chin thoughtfully, other hand on Deku's cock. For a moment Deku thought she may back off, but then she leaned forward and took it in her mouth.

"Ahhn..." Deku moaned. "H-Hatsume..."

She swirled her tongue around, and bobbed her head, and then pulled back with a wide grin. "You taste really yummy."

And then she was back to it, milking Deku's cock for all she could.

It was lucky no one came in sooner, honestly...but that didn't last, and Mei had pulled back and started jacking her off, somehow sensing she was about to cum. She opened her mouth, tongue out, and covered her eyes with her goggles and pointed the oversized cock at her face, but Deku knew she must not know what to expect.

"W-wait, H-hatsume, I...I'll make too much of a..."

It was at that moment the door swung open, and the shock distracted Deku from her attempts to fight off her incoming orgasm.

So, with Shiozaki standing in the doorway watching, wide-eyed in shock, Deku blasted about a pint of cum all over the pink haired girl's face, coating it completely. She giggled. "Wow, Deku-chan. You made quite a mess..."

"S-shiozaki...w-wait, I can explain..." Deku tried to think of how to defuse the situation, but nothing really came to mind.

"Wait, is someone..." Mei, currently blinded by jizz, tried to ask, but was interrupted by Shiozaki finally managing to react. "S...Sinful!"

She turned bright red and spun around and rushed back out of the room, letting the door slam behind her. "Wait!"

Deku leapt up, glancing at Mei who was apparently not too concerned by the interruption, currently scooping up and licking cum off her face.

Deku rush to follow, tucking herself back away as she went, and caught up halfway down the hallway. "Shiozaki, please! Wait"

The vine-haired girl spun around, expression cold, but also blushing intensely. "I cannot stand for my classmates performing such sinful behavior...and in the open!" She sounded calmer than Deku expected. "But I will teach you a lesson myself in our match! I have nothing more to say."

She turned again and stormed away.

Deku felt obligated to go back and help Mei clean up, and unfortunately missed most of the third match as well as the apparently already completed second. She assumed from Shiozaki's comment that she'd beaten Kaminari, it was unfortunate that she didn't get to see her opponent in action again, but it wasn't the end of the world. She had wanted to be there for Tsuyu's match, however.

Mei was wiping herself clean with some napkins when Deku returned, and told her to just go watch the other matches with a grin.

She made it right as Tsuyu was apparently winning the match...she dodged a charge from Iida and caught his ankle with her tongue, tripping him up enough to get thrown out of bounds.

"Good job Tsuyu!" Deku called out from the sidelines.

The frog girl glanced over and gave a smile that was only really noticeable to a few people who knew her well.

She leapt over after the announcement of her victory, and gave Deku a hug. "I didn't see you in the stands, kero"

"I missed the first part of the match...sorry." Deku blushed.

Tsuyu sniffed the air. "You smell like...oh, kero"

Deku blushed deeper. "T-that's um...Hatsume-chan's fault."

"You..."

"N-no...I mean, kindof. I didn't do anything to her, she only did things to me...and it wasn't my idea!"

"You don't have to explain yourself, kero. I told you I was ok." She squirmed. "You smell really...Can we...?"

"I...I don't want to miss more matches. And um...Shiozaki already caught me once today."

"She caught you?" Tsuyu looked worried.

"I don't think she's going to say anything to anyone. I'm not even sure what they'd do if she did though."

"Y-yeah, you...we need to be more careful, kero"

The rest of the rounds were interesting, and informative, for the most part. The fifth match and the final match were the biggest exception, as the bird-headed Tokoyami beat Yaoyorozu so quickly she didn't even really have any time to show off her quirk. From the look on her face, she was crushed by losing so badly, but for what it was worth, Tokoyami seemed to take no pleasure in it either. He probably just knew he needed to end it quickly or he wouldn't be able to win at all.

Sero's loss was even faster, with a frustrated Todoroki freezing the boy almost solid in the worst case of overkill Deku had seen.

The one Deku cared about most, though, was the sixth match. Ochaco put up a good fight against Bakugo. She even managed to, via a series of distractions, to evade Bakugo long enough to lay hands on him and toss the boy into the air, where he had nothing to use as leverage to move...She likely would have demanded surrender under threat of being dropped, until he used his explosions as jet thrusters and essentially flew back down to blast her again. Realizing she didn't have a win condition, and exhausted from lifting numerous pieces of rubble, she collapsed, and was deemed unable to continue.

Something was off, though, about Bakugo. He'd been...distracted. He wasn't fighting as well as he normally did, and Deku couldn't tell why.

Bakugo himself answered that question in the short gap between rounds 1 and 2.

"Hey nerd!" An angry voice called out from behind Deku in the hallway. "We need to talk."

Deku found herself being pulled into an empty room and the door locked by a strong grip. It actually hurt, a bit.

"Ow, Bakugo, what are you..."

"What the hell did you do to me, Deku?" The blonde practically snarled.

"What?"

"What in the actual fuck did your shitty perv quirk do to me."

It clicked. What she'd heard about her addictiveness and pheromones...Deku's eyes flicked down and she could see the prominent bulge in Bakugo's pants. "You...uh..."

"Damnit, nerd. I...I know you did something! I don't want you! This isn't me, it's your shitty quirk! I'm distracted, I can't stop...thinking...Fix it!"

"You're right, it is my quirk." Deku frowned. "But it's not something I can control. I guess chasing me around in the cavalry battle so much brought that...addiction back to the surface."

"Then...then I..." The boy seemed to be frantically trying to think of how to justify himself to his own ego. "I'll just..." He looked down at her and reached to unzip Deku's jumpsuit. "You're going to help me clear my head then."

Deku didn't resist. She did actually legitimately feel a bit guilty about the situation, though that wouldn't have been enough on it's own, but her own quirk was causing her to juice her panties.

She finished the job Bakugo started, sliding down her outfit, but expositing a bit as she did. "Alright, but...you may be surprised."

Bakugo flinched visibly as she lowered her jumpsuit past her panties, revealing an obvious bulge. "You've still got a dick?!"

"Yeah...but..." Deku reached down and lowered her panties, then lifted her balls to reveal her dripping wet slit. "...also this."

Bakugo stared intently at her puffy lips.

"You want it?"

He nodded.

"Go ahead then."

It felt like less than a half a second later he had Deku bent over a desk, and was buried to the hilt in her pussy.

Deku shifted to Frog, just to be on the safe side, but less than a minute later, that was proven unnecessary, as Bakugo pulled out of her pussy, breathing heavily, and thrust directly into her ass.

She squeaked. "H-hey!"

It didn't hurt, but it really should have, even as soaked as she was, as she'd never tried that before, and Bakugo was not gentle.

It must be her quirk at work again.

She moaned in pleasure and couldn't bring herself to resist or even object as he slammed her, and a mere three thrusts later both of them were cumming.

Bakugo stumbled backward, and eyed the puddle of Deku's jizz on the ground with a scowl.

"No one finds out about this, Nerd. Got it?"

"Fine. I won't tell anyone, but if you try that without asking again, I'm cutting you off."

"Fuck off. This isn't happening again. Ever." Bakugo growled, then fixed his clothes and slipped off toward the nearest restroom, leaving Deku to clean up the mess before round 2.
