“Come on. I know you can take more than that, Kacchan.”
Izuku purrs, as Katsuki coughs and pants, shaking his head,
“I can’t. You’re…. too big...”
Katsuki whines uncharacteristically, and Deku tilts his face up, gripping his spikey blonde locks tightly between his fingers. He eyes his rival’s sweaty, flushed face, his lustful, tiredly hooded cherry red eyes, his lips wet and plump and cum dribbled at the corner of his mouth.
“You sound like a quitter. That’s not the Kacchan I know.”
He pushes Katsuki’s head back onto his dick, shoving his entire length into his mouth, not caring when Kacchan gags miserably. He keeps him in place, not even allowing Katsuki to bob up and down as he sucks him off.
“The Kacchan I know,”
He shoves him further, feeling the warmth of Katsuki’s throat encase his throbbing cock, undulating as he tries to breathe,
“--is a slut who loves my dick in his mouth more than anything. So don’t you want to be the best slut you can be?”
He entices, and Katsuki nods as much as he can, letting out a grunt as he squeezes the hand that holds his. Midoriya allows Bakugo to slide back and re-adjust, his lips suctioned on and his tongue giving a swipe at the end as he laps up Midoriya’s cum like he can’t get enough.
“Then say it. You want to be a good slut.”
Izuku instructs, and Katsuki swallows, panting,
“I want to be a good slut…”
“Say you’re my slut. Say you’re a whore,”
“I’m your slut, I want you in my mouth, i’m a whore,”
“Say that you’ll take it all, this time. Otherwise you get none.”
“I’ll take it all, I-Izuku, promise,”
“Then get started already.”
And Bakugo nods, opening wide and taking Izuku into his mouth again, sucking him, slowly going deeper and deeper until Izuku feels his tip meet the back of Kacchan’s throat, but there’s still more to go.
“Go on, Kacchan. You aren’t done.”
Katsuki gags but doesn’t give up, squeezing his eyes shut as he forces more of Deku down his throat, tears springing to his eyes as Izuku’s cock makes it’s way further, filling his esophagus completely. He gags again harshly, sounding in genuine pain, so Izuku releases his grip and takes to gently stroking Bakugo’s hair instead,
“You can do it, baby...you’re so good, just a little more…”
He murmers, completely changing his tone, but not about to let Bakugo give up when he was so close with only half an inch left. Izuku was nearing the edge as well, his crotch hot and pulsing, biting his lip as he feels his dick fill up, poised and ready to release a rocket of semen and finally reach his orgasm. Katsuki seems to share this sentiment, his adam’s apple bobbing painfully but forcing himself further down, tears coming down his face. Midoriya feels the walls of Bakugo’s throat tightening, but he doesn’t give in, and just like the champion he is, manages to give one final push. The minute Katsuki’s lips meet Izuku’s base, his nose tickling his curly bush, his chin pressed against his balls, Izuku loses it. He moans and throws his head back, as he releases his hot load straight down Bakugo’s throat, holding him there a second longer before final releasing him. Bakugo pulls back quickly, still takes care to not let his teeth brush Izuku as he departs, sucking him all the way until Deku feels the cool air meet his wet member, the last remnants of cum dripping out onto Katsuki’s chin.
The blonde is coughing and panting, trying desperately to swallow all the semen stuck in his throat, still pooling in his mouth and dripping down his face.
Izuku suddenly feels sympathy for his lover, kneeling and kissing his sweaty forehead,
“There, there...shh. You did so well, thank you Kacchan.”
He strokes Katsuki’s sweaty cheek, the other finally regaining a bit of composure and opening his ruby red eyes, gulping down the remains of the cum in his mouth and licking his lips.
“I fucking did it, Deku.”
He pants out, a smirk forming on his lips, and Izuku smiles fondly,
“I knew you could. Kacchan is amazing, after all.”
He brushes Katsuki’s damp bangs out of his eyes,
“Now, lets get you cleaned up.
