This was dangerous.

Very.

Very.

Dangerous.

Katsumi glanced at her crisp summer yukata, the pattern was bland, not that it mattered since she was a few minutes away from not wearing it. Her body beneath it was as clean as she could get it and was still all but glowing from the hot spring waters that she had been bathing in nearly twenty minutes ago. Much of those twenty minutes had been dedicated towards making sure that when she met up with Izuku in their room that she'd be looking good. Especially her breasts, it was surprisingly difficult to get those fuckers to stay in place in a Yukata without a bra. But the end result had been worth it.

Probably.

She wasn't exactly the best at looking girly.

The past month she had actually been dating Deku had been absolutely amazing, it felt like nothing had changed, but everything had changed, she talked to Deku more, she hung out with Deku more, they even went on a few dates and made out a lot. And that was when Katsumi discovered what exactly was so dangerous about her relationship with Deku.

No matter how hard she tried, no matter what she did, in the end she was completely and utterly powerless. Whenever Izuku touched her in the slightest possible way, her body would just simply give in. There was no fight, no resistance, her pressing Izuku for more, no her dominating him and demanding more from him. She was just completely lost to his touch.

She had assumed that much like how she was in charge of everything else in her life she would be in charge, that she would dominate everything including the bedroom. But as it turned out.

She was Sub as hell.

And Deku.

Fucking Deku.

Was a Dom.

It was his suggestion that they come out here for his birthday, it was his suggestion that out here they'd finally have the privacy to do what she had been wanting to do for what felt like years.

Fuck.

Like animals.

And now, Izuku was leaving her waiting, just on the verge of sexual collapse like he was teasing her. He was a guy! What the hell was taking him so long? She was getting horny from waiting. Okay she was getting horny about a faint breeze at this point but that didn't mean anything. She was finally about to fucking fuck Deku how could she not be fucking horny? It was a miracle she hadn't jumped him the first moment they had a moment of privacy.

So where the hell was he?

The door opened and Deku came walking in absolutely owning the Yukata with just a bit of his exposed chest exposed, it really looked like the slightest tug in the right spot and Izuku would be completely naked. He looked at her, oh boy did he ever look at her, his gaze following her curves, lingering on her legs, her breasts, and then smiling when he saw her fast.

Her entire body fucking tingled.

"W-what the hell took you so long?" Why the fuck did she just stutter? She did not stutter! She was Katsumi Bakugo! That was it. She was going to be dom today. If she failed now she might never get a chance to be on top. "Get over here and kiss me."

She would have stood up to go to him but at this point her legs were already jello. Izuku complied with a smile, his knee fell in front of her and his hand graced her cheek as he lured her into a long tender kiss. Izuku's kisses were always sweet. At the start, but at the slightest urge from her, they would turn into something far more erotic. And she demanded that from the very start.

The kiss deepened, Katsumi pushing herself into it more, her hand grazing Deku's neck, sliding down to his shoulder pushing his yukata to the side as she greedily demanded more and more from him. He grabbed her like she was nothing, pulling him onto her lap as his hands began the slow process of undressing her. The hand that had caressed her cheeks moments ago was now pushing southward.

His large calloused hands grabbed a handful of her breasts, his fingers sinking deep as he tweaked her already hard nipples. Katsumi gasped, turning from their kiss to see what Izuku's hands were doing, but she made a mistake. She exposed her neck. Izuku kissed her neck softly, sucking on it, making her moan while his free hand extended down towards her legs, grabbing at her thighs and moving upwards and upwards.

His hot breath grazed her as he nibbled on her ear softly, playfully, she could feel his smile with his every action, just as she could feel his excitement building beneath her buttox. His hand paused, less than a hair away from her crotch, lingering there like a predator ready to pounce.

"Katsumi?" He had the balls to ask. "Do you want me to stop?"

"No," she hated how meek that reply sounded, so she reached a hand behind her and wrapped her arm behind Deku's neck, keeping him close. "Keep going. All the way."

"Okay."

She gasped when his finger brushed up against her, prodding her, investigating, getting ready to enter. She needed to act. She needed to do something. With several awkward moves - only made more difficult by how Deku was making her body twitch with his every action - she managed to get a hand under her and into his yukata, she found his dick.

It felt massive in her hands.

Warm.

Large.

Pulsing.

Begging to be put inside of her.

She stroked it, running her fingers up and down it's length in a light half grip.

Deku moaned and shuddered. That sound set her off. Her leg twitching as she felt her insides explode in a flurry of pleasure and she shot backwards, kissing Deku with all of her might. His hand on her breast, his fingers in her crotch, his tongue in her mouth, and his dick in her hand, how was he pressing her in so many ways at once? She couldn't take it anymore. She needed more. She needed so much more.

The clothing was in the way.

Izuku must have thought the same, because she found her yukata sliding off of her effortlessly guided by his hand and tossed somewhere onto their bed for the night. She pressed forward, slowly trying to get his clothes off him, taking the time to explore the body he had worked so hard for as a smile crept onto her face. It was driving her wild just how much she was into Deku.

Like he was just frustratingly hot.

She found herself staring at his bare, raw dick standing right out of his body like a pillar of fucking raw muscle designed to fuck the shit out of her. A single thought entered Katsumi's mind as she looked at it, feeling waves of heat wash over her. Mina got her the wrong size.

"Katsumi," Deku moaned, pushing her onto her back and kissing her bare naked body over and over again, once on each breasts, teeth grazing her nipples, as he held her hands above her head. Her legs were spread wide, her body completely prone, completely submissive to Izuku's whims. God damn, she was a Sub. And she hated how much she loved it.

She could feel the warmth of his member just looming there, the promise of entering her teasing her more than Deku's fingers had.

They shared yet another desperate kiss before Izuku pulled back, her legs resting on his hips as she found her lower body angling itself towards him. "Katsumi," he repeated. "I'm going to put it in now, okay?"

She bit her lip and nodded.

She gasped when she felt Izuku's dick brush up against her, her inner thigh twitching in anticipation, her legs hooked around his waist in a desperate attempt to pull him closer. She needed him. Now. He moved slowly, ounces of pain met her as she felt him spreading her. That pain grew and grew the deeper he went, but, at the same time, this was sex. This was sex with Deku.

Somehow, she took him. All of him. His cute, somewhat boyish face contorted into a look of pure bliss. And then there were his moans, gutural, beastial, dominating roars of someone that was certain of who they were.

"You can move." Katsumi half whispered, her body still heaving from just him entering her. Every part of her body felt like it was on fire, her legs were shaking, her muscles spasming, and she felt like she might be a few moments from completely breaking.

Deku nodded, one hand slamming down right above her head, causing her to quiver with how sudden and down right sexy that move was. He kissed her again, and in the middle of that sweet tender kiss that she was completely powerless against, he began to move in earnest. A slow, steady motion that forced her body to match it.

Then she felt it. The effects of practically edging herself for the month and a half had finally broken her. And she came. Hard. She half screamed lurching forward and grabbing onto Deku kissing him harder, as he continued his slow steady movements.

She felt him laugh. That sound alone was almost enough to make her cum again, and Deku's hand right on the small of her back, just above her ass right where that feeling was pooling around the most, was almost more delightful than his dick inside of her.

"What was that?" Deku asked, smiling as they broke the kiss, his hips still moving oh so slowly, oh so wonderfully in and out of her.

Katsumi bit her lip, if she told him, she'd be giving up even more control. Not that she had any. "I just came."

"Oh. Neat." Izuku sat back, pulling her up with him, so that she was all but sitting on his lap, his eyes locked onto hers. "I want to see if I can do that again."

He did.

Again.

And Again.

He made her cum while she was on her back, while she was on all fours, while she was on top of him, and her favorite, while he was standing and she was hanging off of him, biting at his neck her mind lost in pleasure.

She couldn't walk for a day and a half.

Two years later, she married Deku.

And she couldn't be happier.
