Katsuki and Izuku couldn't stop themselves. Like two opposite ends of a magnet, they were drawn together. Their roaming hands were being sure to leave no part of the other untouched. Their kisses were becoming needier, rather than the passionate lock they were in before. It was more animalistic, noses bumping one another, teeth clashing occasionally. 

Izuku whimpered as Katsuki bit his bottom lip, tugging on it slightly. His hands were lost in Katsuki's ash-blond tufts of hair, tugging it. Their lips returned together, Katsuki's tongue entering Izuku's mouth, which let out moans of approval from both boys. 

As they walked back to Izuku's bedroom, they bumped into walls and side tables but neither cared, their minds on the person who they were destined to be with. Izuku had opened the door to his room and they made their way to the bed. Izuku hit the back of the bed and fell onto it, panting slightly when he separated from Katsuki. 

Katsuki watched as the curls atop Izuku's head bounced softly around his head, imitating a halo, which Katsuki saw fitting as Izuku seemed like his angel. Katsuki placed both hands on either side of Izuku's head and he dipped down, a crooked smile on his face. He pecked Izuku's lips and began to kiss his jaw and down his neck. One of his hands began unbuttoning the shirt, and his lips continued to kiss his neck. Katsuki began sucking, teasing and biting one spot of Izuku's neck, sending him into a frenzy of moans. His hips bucked up, searching for some form of friction and he was met with Katsuki's thigh, which caused him to shudder. 

He had finally unbuttoned Izuku's shirt and was trailing kisses further down Izuku's body. His calloused hands made their way up to Izuku's abs and chest. He teased Izuku's body with light touches and small kisses. Izuku's body writhed beneath him and he was gasping at every touch. 

Katsuki got tired of teasing Izuku and began placing wet kisses down Izuku's chest. He finally Izuku's nipple where he began teasing it with his tongue, enjoying the greenette's moans. "Katsuki," Izuku let out as a soft sigh, his senses heightened and overloading. His hands were playing with Katsuki's hair, his hips grinding into Katsuki's thigh occasionally. Katsuki hummed at Izuku's sigh and his other hand came up to Izuku's other nipple, toying with it as well. 

Katsuki was about to continue further down Izuku's body when Izuku stopped him. Katsuki looked up to see Izuku blushing. Izuku flipped the two around, so Katsuki was now laying on the bed. Katsuki grinned at Izuku's boldness as his shaking hands came to undo Katsuki's shirt. Izuku, similarly to Katsuki, began trailing kisses to Katsuki's chest where he also began teasing Katsuki's nipple's. Katsuki seemed very sensitive in this area because a breathy moan escaped his mouth, which caused Izuku to look at him in surprise. 

"You have a nice chest. You have big boobs," Izuku hummed out before he returned to teasing Katsuki's other nipple. "Hah! You shitty nerd," Katsuki answered blushing, his comment not coming out easy, but rather flustered and embarrassed. Izuku just laughed before he finally moved down Katsuki's body. He placed wet kisses on Katsuki's abs and licked down his v-line, relishing in the shudder beneath him. His hand's made their way to Katsuki's belt when he looked up to Katsuki for conformation. Katsuki nodded and Izuku unbuckled the belt and unzipped the pants.

He pulled down Katsuki's boxers and gasped softly when his dick freed from the fabric. He tentatively grabbed Katsuki's dick and began jerking it off slowly, which turned Katsuki into a moaning mess below him. "Fuck, Izuku," Katsuki moaned out, hips also grinding into Izuku's hands. Izuku blushed at Katsuki's lewd voice. Izuku, nervously, stuck his tongue out and drew a line from the base of Katsuki's dick to the tip. Katsuki moaned loudly and his hand's moved to the top of Izuku's head, where his curls sat. Izuku opened his mouth and took Katsuki, moving his hands and head simultaneously. 

His tongue worked wonders on Katsuki, swirling around Katsuki's throbbing tip, licking every drop of pre-cum that had made it's way out. Katsuki could do nothing but moan and guide Izuku's head by his curls. Izuku hummed the vibrations created by his humming, sending Katsuki to another dimension where stars swam in his vision. "Fuck this," Katsuki moaned before he pulled Izuku off him and kissed him eliciting a surprised squeak from Izuku. Katsuki flipped Izuku so he was on the top once again. He began taking off Izuku's pants and began placing kisses on Izuku's dick.

If Katsuki was loud, Izuku was even louder, unable to contain his moans. Katsuki's warm and wet mouth engulfed him and his tongue was making Izuku go crazy. Katsuki continued to suck and jerk off Midoriya when he began placing kisses lower. He made his way to Izuku's ball's, where he also kissed them before placing kisses on his thighs. Katsuki placed Izuku's legs on his shoulders and began trailing kisses to Izuku's asshole, making Izuku flush and gasp in pleasure. 

Katsuki began licking Izuku's asshole where he raised a finger to Izuku's mouth, which Izuku sucked in pleasure. Katsuki returned his hand to Izuku's asshole where he lifted his mouth off of Izuku and began to slowly insert a finger into Izuku. Izuku gasped and his toes curled over Katsuki's shoulders, and a loud moan escaped the boy. Katsuki continued to pump his fingers in and out of Izuku, occasionally adding a new finger, preparing him for Kastuki. 

They returned to their kisses when Katsuki pulled away. "Are you sure you want to do this?" Izuku looked up at Katsuki, green eyes hooded in lust, "Yes, please." Katsuki's wolfish grin returned as he went to his wallet and pulled out a condom. He ripped the packet with his mouth and slowly began to roll on the condom. "Alright, let me know if it's too much or I need to stop," he murmured in Izuku's ear before slowly inserting himself into Izuku. 

Katsuki let out a low groan and Izuku's mouth just opened, no noise escaping it. Izuku's hands were tightly woven in Katsuki's hair, the intrusion, unfamiliar. Katsuki had finally bottomed out in Izuku and stayed there for a while for Izuku to get used to the sensation. "You can move now," Izuku whispered in Katsuki's ear. Katsuki nodded and slowly began to thrust in and out of Izuku, both of them moaning loudly. 

"Fuck, Izuku," Katsuki moaned, his head dipping to Izuku's neck where he continued placing kisses. Izuku could only moan in reply, his own dick rubbing satisfyingly in between his stomach and Katsuki's stomach. Katsuki's thrusts sped up, the sound of skin against skin, heavy breathing and breathless moans filling the apartment lewdly. Sweat was coating their skin, both on the verge of cumming. 

Izuku began bucking his hips up in between the two of them, needing more friction. Katsuki noticed this and moved his hand to stroke Izuku. Izuku began to feel overwhelmed and he knew that he was reaching his climax. "Katsuki, I'm gonna- I'm gonna- cum," he managed to let out before Katsuki kissed him and began stroking him faster. Izuku's mouth fell open and he came on Katsuki's hand, stomach and his own stomach. 

Katsuki's own high came close after that, his strokes becoming sloppier, Izuku tightening around him deliciously. Katsuki let out a moan, where he said Izuku's name repeatedly and finished into the condom. He pulled out of Izuku and took the condom off, grabbing a tissue and wrapping it before throwing it in the bin. He returned onto the bed where a breathless Izuku was laying. 

Izuku looked at Katsuki and blushed, burying his head into his hands. "You can't be shy now," Katsuki laughed. Izuku joined in his laughter and moved to cuddle Katsuki. Katsuki met Izuku's hand and their fingers intertwined, laying on the comforter. Katsuki raised Izuku's hand and placed a kiss on it. They stayed there in silence, basking in this new feeling of pleasure. 

"We should probably shower," Izuku murmured. Katsuki let out a hum of agreement and together they made their way to the shower. They finished cleaning each other, with a few sneaky blowjobs, and returned to the bed where they fell into a satisfied slumber.
