Chapter Text
"You alright Kacchan?"
Katsuki fights down a snarl from forming on his lips as he sat down across Izuku in the cafe. Sweat beaded on his temples, his breaths coming out as steam, his body too hot too damn early. "I'm fucking fine." He answers. Izuku smiles at him, something there that Katsuki knows is hiding a shit-ton of mischievousness from him.
For your sake, Katsuki is gonna tell you a lil story. You see, right before a whole night of exercise of the carnal kind, Izuku made a bet about wether Katsuki can hold out from cumming in under an hour. Of course he accepted that challenge, because just one hour? Easy. He was confident that he can remain indifferent to Izuku's attempts.
40 minutes later Katsuki is sobbing out of pleasure into his pillow, body vibrating every 5 seconds from a mind-blowing orgasm, legs spread on the bed with his puffy hole fluttering around the flood of cum running out of him. Izuku only kissed and smiled against his shoulder, praising him for doing so well before plunging back in to drill Katsuki's asshole even bigger until his cum frothed. The blonde adapting a fucked out face worthy of being called an 'ahegao'.
Because Katsuki hadn't been able to uphold the bet- three days later, this is his punishment-
"F-fuuuckk..." Katsuki whispered under his breath, his legs shaking as the vibrator in his ass shook with a higher setting, pressed against his prostate. Accross from him, Izuku's smile widened, one of his hands underneath the table playing with a wireless pink remote. Katsuki is tempted to roll his tongue out and pant like a bitch in heat, but his higher brain function screamed at him to not fucking do that especially in public.
They ordered their food and drinks, with Izuku sipping his overly sweet concoction while Katsuki nursed his regular black coffee with a trembling hand while attempting small talks. Well, Izuku talked and Katsuki listened or grunted.
"Kacchan I don't think you're listening." Izuku pouted when Katsuki remained non-verbal.
"No shit sherlock, I'm-" Katsuki made an almost whimpery noise when Izuku dialed up the vibrations again. To his horror, he can actually hear the buzzing more audibly. He clamped a hand over his mouth, his eyes wide and face red as his lover's shoes. He can feel his hole flutter involuntarily, and Katsuki desperately craved solace from it.
He needed Izuku's cock. Badly.
Izuku is aware of the boner in his own pants, but he ignores it in favor of watching his boyfriend try to keep himself under control. He watches the sweat dripping down that thick neck, watches him shift from side to side as if to relieve the pressure of sitting on his ass, and he especially pays attention to his eyes. Those red eyes, teary and seconds away from rolling up in bliss.
Izuku fiddled with the remote in his hand before cranking it to it's highest setting.
Instantly, Katsuki jolts in front of him and bows over the table, one of his arms slamming on it to prevent himself from melting against it, the sound attracting a few heads. Even from where Izuku sat, he can hear it. The continuous buzzing of the toy he stuck in Katsuki's ass.
"Deku," Katsuki growled, face red and ready to leap over the table. Either to fight or fuck, he doesn't know yet.
"Yes Kacchan? Is something the matter?" Izuku asked back innocently.
"Fuck you." Katsuki settles on saying, his mouth opening around a gasp. His eyes glared at Izuku from accross the table, but his pupils are so blown there's barely any red of his iris left. "Fuck you so fucking much."
Izuku knew Katsuki meant it as an insult, but he couldn't help tease, smirking. "Begging already Kacchan? But we haven't finished our food yet."
Katsuki is seriously tempted to leap across the table now, determined to either clock Izuku on the head or whip that big dick out and sit on it, audience be damned. In the end, he decided to throw pride out of the window, by saying. "Please, take me home."
The sight of Katsuki saying such sweet words is what made Izuku dial down the toy to it's lowest setting, until it's just a pleasant little buzz. The blonde instantly slumps on his seat, sniffing, and fuck- Izuku is so turned on just from looking at him. All red-faced and teary eyed, desperation written all over his face.
Izuku wants to see the blonde completely fall apart underneath him, wants to feel Katsuki claw at him from euphoria, wants to hear his voice become hoarse from screaming in pleasure. Until he all but obliterated that cute and pink little fuckhole until it struggles to close.
So Izuku paid for their orders and took his boyfriend home. Katsuki is more than glad to go with him, rear end clenching in excitement.
Izuku had plans for that ass, even that mouth. And Katsuki had the same train of thought because as soon as they arrived at their high rise apartment, the blonde went down on his knees and hurriedly unbuckled Izuku's pants. To which the green-haired man whispered a low, "Good boy." That sent a pleasant tingle up the blonde's spine.
Izuku's head landed with a thud against the door when Katsuki's hot mouth descended over the head of his cock, and looking down, he catches the other swipe up the pre that beaded there with his tongue, curling it up into his mouth with the sexiest smirk to ever grace such a handsome face. Izuku's cock throbbed.
Katsuki's smirk dropped when Izuku tugged at his hair, hissing at the slight pain. "Oi what the fuck!"
"Get up, get naked, get down, and crawl towards the bedroom." Izuku says, taking himself in hand, enjoying the way Katsuki's eyebrows rose to his forehead. "Provide me your appropriate answer."
"G-green." Katsuki manages to stutter out through his surprise, his red iris all but pushed back from how blown his pupils are. "Green."
"Good. Get to it then."
The only thing Katsuki's mind is filled with is 'Holy shit' like a continuous mantra, getting up to do what his master says.
Deku has trained him too well to not obey.
