Izuku forgot to close the bedroom window, so a puddle formed on the carpet as it began to rain. But they were so caught up in each other neither of them noticed. Even as thunder boomed and lightning flashed, illuminating the dark room, it didn't distract them once.

Katsuki laid Izuku on his back, then quickly climbed onto the bed to hover over him. They barely broke away their kissing, even while they tore each other's clothes off.

Izuku's heart raced. It's happening, he thought. It's finally happening.

Since Izuku moved in, Katsuki had been more patient with him than he'd expected. More than once he was the one to pump the breaks if he thought they were moving too fast, while Izuku rushed through their intimacy like a kid eager for his dessert.

But now he wasn't holding back.

Katsuki was already readying him, entering Izuku with lubed fingers and making quick, deep jabs straight into his sweet spot.

It was pure heaven. "Ahh! Aah! Aaah!" Izuku gasped into his boyfriend's mouth. He dug his nails into Katsuki's back as he writhed beneath him. "M-more," he begged.

Finally, Katsuki pulled away from the kiss. "Are you sure?" he asked huskily.

Izuku gritted his teeth. "P-please."

"I'm only using two."

"P-please! AHH!"

He saw stars as Katsuki added a third finger, thrusting slower. "I don't want to hurt you," he insisted, looking down at Izuku with a worried expression.

He shuddered, rocked by his ecstasy. "We've b-been practicing," he assured. "I'll b-be f-fine."

"It's only been a few weeks - "

" - I'm ready - "

" - Wanting it doesn't mean - "

" - I love you Katsuki and I need you," he shuddered, his gaze flooded with desire. "Please."

It was as if someone flipped a switch. The worried look in Katsuki's eyes was gone. In it's place was pure, aching lust. Unwavering arousal.

Without saying a word, Izuku understood. There was no turning back now.

Katsuki removed his fingers and grabbed Izuku's thighs, turning him at a certain angle and fixing his hips in place.

A shiver of pleasure went through him as his insides clenched, aching to be full. Katsuki lined himself up with Izuku's entrance, and then all at once, he'd thrust his whole length into Izuku.

"KACCHAN!" Izuku screamed, throwing his head back. It was so much more than he'd thought. He'd never been this full before. He couldn't even see straight. All he felt was pleasure and pain. But the pleasure was winning out.

Katsuki let out a quiet sigh, his body relaxing, as if relieved. "What's...Kacchan?" he asked softly, dazed.

Izuku flushed shyly, covering his eyes. "I'm sorry," he mumbled. "I didn't mean to say - "

" - What does it mean?" he asked again, breathless.

How embarrassing. "It's...it's what I call you in my head," he muttered. "It's dumb, but I - "

" - It's okay," Katsuki whispered, thrusting slowly.

Izuku groaned, overwhelmed. "Oh…Kacchan….AAAH!" Out of reflex, he stuck one hand in his mouth and the other between his legs to stroke his erection.

"I'm driving you crazy, aren't I?" Katsuki asked with a satisfied smirk. "You can't even control yourself, can you?"

Izuku whined, bucking his hips to meet Katsuki's thrusts once he got used to the fullness.

"So greedy," he growled low. "Even while I'm inside you," he thrust all the way to his base, "Filling you to the brim," he thrust again, deeper, "It's still not enough."

Izuku shoved his hand farther into his mouth as he felt himself get close. But Katsuki pulled his hand away and pinned his wrist down on the bed.

"KACCHAN!"

"I have a name for you too," Katsuki whispered, biting the side of Izuku's neck.

"What is it?" Izuku asked, struggling to free his hand.

"Bunny," he admitted against Izuku's ear. "My naughty, greedy little bunny."

Oh hell. Izuku would've cum right then and there if his mouth had been full. "Kacchan, please, I need to - "

" - How does it feel?" Katsuki asked, thrusting faster. "To be tormented like you've tormented me? It's frustrating, isn't it?"

"I'm sorry," Izuku whined, doing his best to wriggle free. "I'll never do it again, Kacchan. I promise - "

" - I'm not mad," Katsuki said, kissing Izuku's mouth. "I get it now. Why you do it. It's hot."

Izuku hated it. His boyfriend was ramming his sweet spot over and over. At the perfect speed. The perfect angle. Pleasing him so thoroughly it was as if he'd written the blueprints for Izuku's body himself.

But he just. Couldn't. Cum.

"Kacchan, p-please - "

" - Where's your toy, Bunny?" Katsuki asked, tilting Izuku's chin up.

Izuku flushed. The...the drawer...in the nightstand."

Katsuki's gaze darted to the side table, then back at Izuku with playful mirth. "I didn't know that. You've been sleeping next to me with it so close? This whole time? I'm not sure how that makes me feel."

Izuku's frustration was quickly morphing into anger. "You're not exactly the type to talk about your feelings, Kacchan."

The blonde reached over Izuku's head to open the drawer, and pull out the purple metal plug. "You're right," he said. "I'm not. I'm doing all kinds of things I never thought I'd do. You're changing me."

Suddenly Katsuki lowered his forehead to rest against Izuku's. "Your love is changing me," he whispered, kissing him. "Fast or slow?"

"Fast," Izuku whispered back.

Katsuki snickered. "I knew that's what you'd say." He held the toy above Izuku's mouth, just out of reach. "Is this what you want?"

Izuku glared at him, pushing against Katsuki to get to it. But as he thrust again, Izuku gasped, clawing into the blonde's arm. "Give it to me," he begged.

It wasn't fair, but Izuku knew Katsuki understood. Denying Izuku the toy was the same as saying "I know you want to cum. I don't care."

"You've never looked so hot," Katsuki shuddered. He thrust again, holding the toy in one hand and stroking Izuku with the other.

It all felt so good. Katsuki's hand movements were perfectly in sync with his assaults to Izuku's sweet spot. Izuku reached desperately for the toy but it was no use. Katsuki had it behind his back now.

"You have no idea," he whispered. "How long I've wanted this. Wanted you. I'm gonna savor every second."

"Kacchan - " he whined.

"Suck," Katsuki demanded, shoving a finger in Izuku's mouth.

He didn't need to be told twice. Izuku blissfully sucked Katsuki's thumb, panting as an orgasm finally started to build.

"You know the rules," Katsuki said. "If you can handle this, you get more."

He groaned, frustrated again, when it still wasn't enough to push him over the edge. He'd gotten so used to sucking Katsuki's cock that smaller things didn't satisfy him the way they used to. Not even his lollipops. They were enough to rev him up but not get him off. He needed more.

After a few minutes, Katsuki slipped another finger past his lips. Izuku gripped his boyfriend's wrist, desperately trying to shove in more fingers.

"You weren't kidding," Katsuki gasped with half-lidded eyes. "You really can't cum. I bet you want to, though, don't you?" He slipped in a third finger.

Yes, Izuku thought. Please. I'm so close. Please! PLEASE!

"You're doing so good, Bunny," Katsuki muttered softly. Izuku felt his body start to tremble. He was close, too. Not as close as Izuku but he wouldn't be far behind. "So good. So….good. So good! So...oh! Fuck - "

"Please," Izuku tried to say but Katsuki's fingers stopped him from forming words. Let me cum with you. I want to finish together. Please, Kacchan -

In the span of a second Katsuki pulled out his fingers and stuffed the two-inch-wide toy past Izuku's lips until all four inches of it were going down his throat. "Izuku - " he moaned, pressing his face into Izuku's hair.

The toy had barely been in Izuku's mouth for five seconds before pleasure crashed over him and he finally got his release. His legs tightened around Katsuki's hips. His hands somehow made it into the blonde's hair and pulled it. His climax seared every nerve like a hot brand. The toy was shoved in so far it was hard to breathe. He didn't have the air to scream or cry out Katsuki's name or make any of the sounds that were deafeningly loud in his head. But he'd never felt so satisfied in his life. Katsuki even managed to get his hand back on Izuku's erection in time. As he rode his own orgasm, he moved it gently and slowly up and down.

Thankfully, the storm seemed to speak for him. The roar of the rain intensified. Thunder boomed even louder than before. The lightning striking across the sky was just as blinding as Izuku's pleasure.

The last thing he knew was Katsuki's warm body securely wrapped around him and the smell of bourbon body wash before everything went black.

~.~

Izuku woke up in Katsuki's arms, pressed against his chest. A warm, tender hand lightly stroking his hair. A calm, steady heartbeat bah-dumed against his ear.

Izuku looked up. Katsuki had his eyes closed. "You're falling asleep," he whispered.

"Mmm," he replied gruffly.

"How long was I asleep?"

Katsuki yawned, shaking his head. "Dunno. Just woke up."

"You still have your eyes closed."

"I'm tired."

"Strange. I wonder why."

Izuku's heart leaped as Katsuki let out a rare laugh and grinned wide. "You think you're funny, don't you?"

Izuku propped himself up on his elbows and shot a defiant smirk. "Yes, I do."

"Well, you're not."

Izuku loomed over him, balancing on his palms. "Then why did you laugh?"

Katsuki finally opened his eyes, his smile disappearing. He reached up to cup Izuku's face, rubbing his thumb gently over his cheekbone. "You have the most amazing eyes," he muttered quietly. He'd spoken so softly Izuku thought he imagined it.

Izuku placed a hand on top of Katsuki's, kissing his boyfriend's thumb. "You look sad again."

"What?"

"You get this look on your face sometimes. Like you're scared. Or sad."

"No, I don't."

"Yes, you do."

"I'm not sad."

"Then why do you look sad?"

Katsuki swallowed, glancing off to the side. "I was just...thinking something."

Izuku adjusted himself so he was straddling Katsuki's stomach, sitting upright. "What?"

He let out a deep sigh. "If I'd known you...while I was in high school...I never would've started getting into fights."

"I'm glad you did," Izuku whispered, moving Katsuki's hand to his lap to cup it in both of his. "If you'd never got in trouble for fighting, your mom wouldn't have made you get a job. And we never would've met."

"You're right," he whispered. "Like you always are."

Izuku squeezed his hand. "I wish we'd met sooner."

"I wasted so much time," Katsuki scolded himself. "I'm sorry."

"It's okay," he assured. "I'm glad we're together now. I used to be so lonely."

"Me too."

Izuku smiled warmly. "At least you had your friends. I always saw people visiting you at work. Sero, and Keigo and Kirishima and - "

Bakugo flushed red and averted his gaze.

His eyes widened. "It's true, isn't it? What Mina said."

Bakugo turned to him, looking alarmed. "Mina said - "

" - She was completely wasted so no one believed her," Izuku assured.

Bakugo sat up, rubbing his temples. "I didn't think she remembered."

"Why wouldn't they remember?"

Bakugo shook his head. "It was pitch dark. Mina was half-asleep. He and I were drunk. I didn't drink as much as he did, but…"

Izuku noticed the V that formed between Katsuki's brows the more he talked about it.

"I woke up first. I bailed before the sun rose. Then they never talked about it, so I never did either."

"Did you love him?" Izuku asked with wide eyes.

His answer was immediate. "No. Not like that."

"So it was...an accident?"

Katsuki's jaw tightened. "Izuku, I don't wanna talk about this."

"I'm not upset," Izuku assured. "It happened before we were dating, right?"

Katsuki slid Izuku off of him and grabbed for a pair of sweatpants. "That night was a clusterfuck. Okay? Can you drop it?"

"Did he hurt you?"

"No."

"Was it bad or something?"

Katsuki snarled, stomping into the kitchen. Izuku quickly slipped into a pair of athletic shorts and followed. "Katsuki - "

" - I didn't know she was gonna be there," he suddenly burst, ripping at his hair and pacing. "He never told me that. She was nice to me but then I started remembering shit that - " he cut himself off, gritting his teeth. "I dunno! Her nails were like my mom's and...and I realized I couldn't do it but I just…"

"They forced you?" Izuku asked, his heart pounding.

"NO!" he exclaimed. "I had to. I just...I just had to. The second I walked into his damn apartment it smelled like you and - "

Izuku's jaw dropped. "What?"

His face was beet red as he stuffed his hands into his pockets. "His mom dropped something off. Cinnamon rolls or...or something. It smelled like you. I was drunk and it was dark and it was easy to pretend - "

" - Are you saying - "

" - It was the only way I could get through it," he admitted, his eyes misty. "It's not his fault. He's a good guy. But...afterwards, when I laid next to him, in my head I was lying next to you and then I woke up, thinking I was but it was all - "

Izuku made it over to him before Katsuki broke down. He hugged him tight when the blonde laid his head on Izuku's shoulder. Kissed his hair when his tears spilled down Izuku's arm.

His words from before echoed in Izuku's mind.

You have no idea how long I've wanted this. Wanted you.

"You don't have to pretend anymore," Izuku whispered. "I'm here. And I'm not leaving."

"You will," Katsuki sobbed. "You'll have to."

"No. Not without you."

"Izuku - "

" - You said I can stay here as long as I want."

"Next year, after you finish school - "

" - Wherever I go, I'm taking you with me. Even if I have to drag you by your - "

" - I love you," he whispered brokenly, sinking until they were both sitting on the floor.

Izuku gasped. He'd never said it before. Not once over the past three months. He didn't need to hear it to know, but it broke his heart.

Because he knew what Katsuki was really saying.

Don't leave me.
