Katsuki held onto Izuku's words all day.

"Kacchan... I... I want to go all the way with you..."

He bit his lip, looking out the window.

They obviously couldn't do it in the shower for their first time, especially before classes.

Still, Katsuki had been caught off guard. Sure, he wanted to go all the way with his boyfriend, he just was surprised.

So surprised that his fists exploded. He shattered the shower glass and destroyed his shampoo.

Now he has to stay in someone else's room while his bathroom is repaired. Obviously he was going to stay with his boyfriend, but is Izuku sure he's really ready for that? Is he ready for that commitment?

Katsuki's been dying to do that with him for the seven months they've been together and longer, but now that it's been brought up, he wasn't sure. Was it really okay?

"Bakugo."

The explosive quirk user snapped his head up. "Yeah?"

Aizawa raised a brow, holding out his hand. "Your homework?"

"Oh, yes." Katsuki reached into his bag and pulled out the paper. He handed it to his teacher.

"Pay attention. Stop zoning out."

"Right..."

"Kacchan, you've been really distracted today... Is it because of what I said..?"

Katsuki looked over to Izuku as he shifted nervously. His expression portrayed his worry.

"Yeah... It is..." The blonde sat beside Izuku, looking down.

Izuku gulped and bit his lip. "Kacchan... We don't... We don't have to-"

Katsuki shook his head. "No, that's not it," he muttered, grabbing his hand. "Deku-... Izuku, I've been wanting to... For a long time. I just wasn't expecting you to come out and say it, then I started thinking, you know, that maybe you weren't really sure if you were ready or if you thought you were ready because we do all the other stuff we do or because we've been together so seven months and some people have done it after being together for a shorter period of time and I just-"

"Kacchan!" Izuku shouted, squeezing Katsuki's hand. He grinned and giggled as Katsuki looked to him with wide eyes. "You're starting to sound like me... Oh, wow. Never thought I'd say that."

The explosive quirk user huffed, looking away.

Izuku shifted, then twisted and swung his leg. Katsuki gasped, eyes widening. He leaned back slightly and looked up as his boyfriend straddled his lap. "Kacchan... I've been thinking about it... I'm ready... I want this. I want you."

Katsuki gulped, then smirked, placing his hand on Izuku's waist. "Wow... Didn't think you had it in you to take charge like that."

"Mm, I guess there's still some things you have to learn about me, Kacchan." Izuku pecked his lips and pushed him back to lay on the bed. "For instance, I got lube and condoms in my desk drawer."

"Oh, yeah? I'm gonna have to take advantage of that." Katsuki reached up, tangling his fingers in Izuku's hair as he pulled him down.

Their lips connected softly, bodies pressing together. Katsuki rolled them over, chuckling as Izuku tugged on his uniform jacket. "Eager," He teased, kissing down Izuku's neck.

The green haired boy sighed, tilting his head back. "I'm just... Ready..."

"Good," Katsuki sighed, holding him by his waist.

Their clothes shed quickly and eagerly, bodies grinding together feverishly.

Katsuki gripped Izuku's thighs, biting and sucking on Izuku's neck.

Izuku bit his lip, holding tightly onto Katsuki's arms. "Kacchan... Kacchan, please..." He panted, reaching over to his desk. He fumbled with the top drawer, grabbing what they needed.

"Give me a second, Deku..." The blonde murmured, taking the tube and package away from him. He got up on his knees and pulled his boyfriend's hips onto his lap.

The green haired boy looked up to Katsuki, face flushed red. His fingers curled into the bedding as Katsuki pulled off his boxers, hungrily eyeing his body. Izuku shuddered at the gaze, hooking his legs around Katsuki's waist. "Kacchan..." He whispered, drawing Katsuki's eyes up.

Katsuki licked his lips and leaned down.

Lips meshed together, Katsuki's fingers kneading into Izuku's thighs. Izuku gasped softly, back arching as Katsuki rocked his hips, grinding against him.

The blonde chuckled, popping open the tube. "For how muscular you are, Deku, you radiate bottom energy."

Izuku's face lit up and he shoved Katsuki's chest. "Kacchan! We don't have to do this-"

"Oh no, we are doing this." Katsuki huffed, spreading the lube onto his fingers. "You asked for it, nerd. You don't get to back out now." He smirked at the pout the other boy gave him.

He leaned back over, kissing and marking Izuku's chest. Izuku sighed, biting his lip as a finger slid into him.

"Does it hurt," Katsuki asked softly.

Izuku shook his head, fingers threading back into Katsuki's hair. "No... Just feels weird..."

Katsuki hummed and nodded, pumping the finger for a moment before adding a second. After a few strokes, Izuku shifted his hips and bit back a moan. Katsuki scissored his fingers, smiling at the gasp it drew from his boyfriend.

With a third finger, Izuku turned his head and arched. Katsuki paused a moment, then continued. Izuku panted softly, grip on Katsuki's hair tightening.

"Izuku, does it hurt..?" The blonde propped himself up on his free arm, brows drawn together as he looked down to a red Izuku.

He gulped, eyes lidded as he returned Katsuki's red gaze. "A... A little... But... It also feels good..."

Katsuki leaned back down, kissing him softly. He took his fingers out, noting the small shudder it caused.

Izuku was reluctant to release Katsuki's hair as he got up, grabbing the package he had set aside. "Last chance, Izu... Are you sure..?"

"I love you, Kacchan..." The green eyed boy smiled softly, sitting up. He took the small package from Katsuki and ripped it open. "I wouldn't have suggested it if I wasn't sure." Izuku tilted his head and bit his lip, unraveling the condom onto Katsuki's dick.

Katsuki gulped, cock throbbing and twitching. "Fuck, Izu..."

The slightly smaller boy smiled and cupped Katsuki's face in his hands. "I love hearing you say my name... It makes me feel special."

"Izuku," Katsuki crooned with a smirk, stealing Izuku's lips in a gentle kiss.

They lay back down, Katsuki spreading lube on his member. Izuku held Katsuki's shoulders as the blonde lifted his leg.

Izuku gasped, head dropping back at a slow intrusion.

Katsuki bit his lip, gripping Izuku's thigh and hip. "Oh, fuck... You're so fuckin' tight..." He pressed deeper until he was completely inside Izuku's warmth. It wrapped tightly around him, inviting and cozy.

"Move... Please, Kacchan..." Izuku breathed out, one hand trailing back to Katsuki's hair.

The explosive quirk user nodded and slowly began to rock his hips.

They both panted softly, Izuku starting to moan.

Katsuki kissed and nuzzled his neck, pressing his nose into Izuku's racing pulse. The hand on Izuku's hip trailed behind Izuku's back and pulled their bodies closer.

The heat was intoxicating as well as Izuku's breathy moans. Katsuki memorized the way Izuku's naked body felt against his own. He wanted more of this boy.

Izuku gasped, head dropping back as Katsuki angled his hips. "Oh, God..." He tugged on Katsuki's hair.

Katsuki grinned, moving at a faster pace. Izuku's moans got louder, walls clenching and twitching.

"Damn, Izuku..." Katsuki kissed wetly up Izuku's neck, fingers kneading into his thigh. "You feel so fuckin' good..."

"Y-you, too..." Izuku managed to speak, tilting his head. "So... So good inside me... Kacchan..."

"Good..." Katsuki moved faster, biting his lip.

Izuku's eyes rolled, grip tight enough on Katsuki that the blonde could feel his short nails. "O-oh!" He gasped, eyes beginning to water.

Katsuki grunted, cock throbbing as the knot in the pit of his stomach strained. He could feel Izuku near climax as well, walls clenching, pulling him in deeper.

His head started to spin, hazy with heat.

"Katsuki-!" Izuku cried out, arching sharply as he released all over their abdomens.

The blonde bit hard on his lip, thrusting more erratically. He grunted as release finally came, eyes closing tight and fingers digging into Izuku's skin. "Fuck-!"

They panted heavily, neither releasing the hold on the other.

Katsuki licked his lips and raised his head. Their hazy gazes met for only a moment before they both leaned into a soft kiss. Katsuki savored Izuku, holding him tight and breathing in his scent. He relished in this feeling of completeness.

He felt whole... At peace... Especially as he gazed into Izuku's vibrant green eyes.

With a deep breath, Katsuki pulled out and removed the condom.

Izuku shuddered, then watched as Katsuki used a shirt to clean off their stomachs.

"So gross," he muttered as he tossed the shirt aside. Izuku smiled slightly, murmuring an apology.

They shifted around on the bed until they were comfortable. Katsuki grunted as he pulled the covers over their naked bodies. Izuku nuzzled into his chest and Katsuki draped his arm over Izuku's waist.

"I love you, Kacchan," Izuku whispered, relaxing.

Katsuki smiled softly. "I love you, too, dork..."
