Tsundere and Sin-namon Boyfriends (Completed)

Chapter 6: Giving In (DkBk smut)

(2 and a half months later)

Late into the middle of the night, a lone figure exited out of his dorm room with a silent click of a door. He walked with quick but inaudible footsteps, green curls bobbing slightly on his head with every step as he made his way to the fourth floor of Heights Alliance. There he made a beeline towards the most familiar door, where he knows his partner is waiting for him.

Indeed, there he is sitting on his bed, stripped of every clothing, blonde and gorgeous as ever. Green eyes made a quick but appreciative scan of that broad and impressive physique before he too removed the shirt and shorts he's wearing. Katsuki drags him down with him when his body is bare, connecting their lips together in a passionate kiss.

They navigated around their new and fresh relationship those months ago, learning and relearning. Dates were cloaked under study sessions, sneaking around the dorm because they were both not ready to reveal it to their friends. They kissed a bunch of times, until it escalated into making out, then heavy petting, until the time came where they were ready to finally initiate some more intimate contact, aka s€x.

It had became obvious to them both that Izuku is as s€xually charged as Katsuki himself if not more so, and the green-haired male can't lie to himself anymore. He just wants Katsuki really badly. So they f*cked for the first time and several more times after, they even almost broke Katsuki's bed as they dumped all s€xual frustrations they've been repressing on each other. They were both loud and unrestrained with slapping thrusts and wet kisses, møaning and grunting with absolutely no shame whatsoever. Katsuki was the one who topped those first few times, never failing on sending Izuku into a delirious mess but then yesterday Izuku asked to switch, and Katsuki decided its time to give himself completely to the other.

Back to the present, Izuku breaks their lip lock, one of his hands having snaked their way around to bury his fingers between Katsuki's round a$$cheeks, feeling how slick the skin is. He found the slightly puffy høle, already gaping slightly under his fingers. He thrusts his middle one inside, humming approvingly at how soft and stretched Katsuki is. "Kacchan prepped for me?"

Katsuki twitched slightly at the thick finger in his a$$, "I thought you'd like it if you get to f*ck me right away." He answered, mouthing around Izuku's jaw while he j€rked the other off with teasing strokes, thumbing the fat head and smearing the pre all over the thick length. "And you're already so hard for me." He smirked at the grøan his words got out of the greenette. "You really wanna rail and mess this a$$ up so much that it didn't take you long to be this big and thick? I sure hope nobody saw you with this thing pushing against your pants."

Another thing they discovered is the dirty talk. Katsuki apparently has a talent for it and he doesn't shy from laying it on thick if it means Izuku will melt right where he stood. His boyfriend is actually a deviant behind doors, Izuku should have expected less.

"Not to worry, Kacchan. This is all for you." Izuku's voice showed promise, deeper than normal, and for the life of Katsuki he feels excitement course through him. The smirk bloomed into an outright salacious grin.

Katsuki turned around to brace his arms on the bed and confidently presented to Izuku his perfectly round bottom. Muscled but Izuku knows with every fiber of his being it's also packing enough meat to jiggle should it be hit by ramming hips or a swift palm. Izuku almost went down on his hands and knees to prostrate in gratitude to god as Katsuki stoked his arousal by reaching back and spreading himself apart, showing him the stretched and glistening skin of his pink høle. Izuku's l€ngth twitched in excitement. "Well, what are you waiting for?" Katsuki asked while looking over his shoulder, his voice low and breathy.

And that was what made Izuku go down. He grabbed a handful of each globes of that a$$ on either hands before he went forward and gave Katsuki's twitching høle a loving lick.
