I wrote this at 4AM so forgive me if it's trash

Putting on his white, fuzzy bunny slippers and his signature black tank top, Katsuki dragged his feet to Izuku's room in the UA dorms. It was late at night according Katsuki's standards, which is only 10PM, and he just couldn't get to sleep. Maybe his cuter and cuddlier boyfriend could help with his problem.

After arriving at Izuku's door, Katsuki knocked, wincing slightly at his aching arm from today's training. He forgot all about his pain when Izuku opened the door, standing in front of him with tired eyes and an oversized t-shirt that was probably his. Katsuki's eyes skimmed through Izuku's smaller figure, eventually landing on his bare thighs.

"Hi, Kacchan," Izuku greeted tiredly, yawning and stretching his arms. The t-shirt he was wearing lifted up slightly, revealing his thighs in all their glory.

"H-Hey," Katsuki gulped, trying to tear his eyes away from Izuku's lower half until Izuku snapped to get his attention. He laughed to play it off.

"What are you doing here so late?" Izuku asked, throwing his arms around the taller male, Katsuki automatically wrapping his arms around his waist. He carefully lifted up the oversized shirt and ran his hands gently over the soft skin on his back. Then he realized that Izuku was only wearing underwear. He smirked, finally resting one of his hands on Izuku's butt and the other on his lower back, causing Izuku to press against him at the touch.

Katsuki sighed before answering. "I can't sleep. Can I come in?"

Izuku bit his lip as Katsuki's hand began to roam his behind, catching a feel of one of the cheeks in the process, making Izuku squeak.

"S-Sure," He pecked Katsuki's lips, "But don't try anything, I'm not in the mood."

Katsuki rolled his eyes and scoffed as he was being pulled in by his boyfriend.

Izuku climbed into his bed, purposely going slower so Katsuki could get a good and long view of his ass poking out of the oversized tee. He was driving him crazier than he already was. Katsuki followed Izuku shortly after drooling over his ass. After getting under the blankets, he immediately pulled Izuku closer to him by the waist, burying his face in his chest and breathing in his sweet scent. Izuku hummed contently, hugging Katsuki back.

"Would you like me to sing you to sleep?" Izuku asked quietly, gently combing through Katsuki's hair with his fingers.

"Mm-mm," Katsuki mumbled, feeling himself getting tired already. Izuku hummed in response.

After spending a few moments in comfortable silence together, Izuku began to fall asleep, while Katsuki's eyes were still open. He lifted his head up, careful not to wake up the sleeping beauty in his arms. He stared at Izuku's pretty face as he slept, his eyes falling on his freckles on each side of his cheeks. He leaned in and captured the resting male's lips in his own, their lips fitting together perfectly like a puzzle piece.

Katsuki's lips rocked against Izuku's as he still slept. He began to get hungrier the longer the kiss went on, not to mention it was painfully too slow for him, he wanted more. He rolled over so that he was hovering over Izuku. He pulled apart for a second before connecting their lips once again, this time using more force. It took him by surprise when Izuku began kissing back with his eyes still closed.

"Mmm," Izuku moaned. He subconsciously wrapped his arms around Katsuki's neck, pulling him close enough for Katsuki to gain access to the inside of his mouth. As soon as their tongues met, Izuku's eyes shot wide open. He pushed Katsuki away in panic.

"Damn, Deku, It's me!" Katsuki shouted angrily, wiping away some saliva on his mouth.

"Sorry! I wasn't expecting to get kissed while I was sleeping." Izuku said sarcastically. Katsuki groaned.

"Whatever. Now let me continue." He swiftly spread Izuku's legs and settled in between them. Before his lips touched Izuku's again, Izuku stopped him by placing his hand on his face and holding him in place.

"Now hold on. I remember telling you that I'm not in the mood." He said with a questionable look. Katsuki groaned louder.

"I fucking know that! I'm not sucking your dick, I'm just kissing you!" He responded through Izuku's hand. Izuku pushed forward a bit after Katsuki leaned towards him.

"You know what kissing usually leads to, especially when we're in bed!"

Katsuki was getting pissed. He can't help the sudden urges he gets to just ravage Izuku with his love. If anything it's Izuku's fault for being so damn cute and irresistible that his heart can't take the pressure anymore.

The two males had a staring showdown. Both of them were watching each other, waiting for one of them to make a move and catch them, until Katsuki sighed and gave up. He laid his head on Izuku's chest, enduring the aching feeling of his heart and not being able to do a thing about it.

"Good Kacchan. Go to sleep." Izuku cooed, stroking Katsuki's head and closing his eyes.

"But baby," Katsuki whined, lifting his head to look at Izuku with a slight pout and pleading eyes, "I want kisses!"

Katsuki can be such a needy baby sometimes. Sure, he is still big and bad Kacchan with a hot temper and great sex appeal in Izuku's eyes, but he still has his moments as the needy, whiny baby he can be.

Izuku stared at him. It took the power from all 8 holders of One For All to resist such a heartbreaking plead.

"N-No way." He replied, looking away with a blush. Katsuki whimpered.

"Baby please?" He crawled up to Izuku's neck, planting streams of soft, wet kisses to his neck, slowly inching his way up to his mouth. During this, Izuku didn't move a muscle. How could he when he was being treated so sweetly like this?

"Just one more?" Katsuki muttered against Izuku's quivering and parted lips. Izuku's eyes darted from his lips to his eyes, falling slowly and deeper into the small pleasure he was given to respond.

Katsuki took his silence as a yes and, at last, fully kissed him. Izuku officially drowned in the tender love and gentle touches of his needy boyfriend.
