His chest heavy and bare in front of Katsuki, with his pale skin littered with freckles and his nipples circled by a rosy pink hue. He shivers under the other’s heavy stare, the cool air making his nipples pebble and become erect. Katsuki swallows drool pooling in his mouth, thoroughly excited to devour his meal splayed out and ready for him.
“Please… don’t be so rough,” Izuku musters out with wine-colored blush covering his freckled cheeks and shoulders. Katsuki grins excitedly while lowering himself to be eye-level with his pecs. He reaches out to scoop underneath one of his tits, lifting it up and watching it jiggle slightly as he toys with it.
Katsuki releases his pec and watches it jiggle back to its original place. The blonde moves his head closer and closer until his lips hover over one of his nipples. His breath is warm against the cool flesh and the other barely holds back a moan from the difference of temperature around his teat. He stretches his tongue out, debating last minute if he wanted to indulge himself, but he decides to kitten lick his teat. Izuku holds back a groan between his pink lips, trying to sit still as Katsuki licks once more, twice more, thrice more. He flicks the bud with his tongue, swirling his tongue around the nub, flattening his tongue against Izuku’s stiff nipple.
He’s squirming in his spot, unable to control his own twitches and movements as the other assaults his chest. “…Please…,” he begs, his green eyes blown with lust as he looks under his chest to meet with blood red eyes, “try… sucking…”
As if Izuku were god itself telling you the ten commandments, Katsuki pants heavily above his nipple, before kissing his whole teat, he teethes at his nub, relishing the way he jerks his head back at the reaction with a guttural moan. Before Izuku can recover, Katsuki suckles lightly as the green man originally asked.
It feels nostalgic, in a way he can only place reminiscent of being an infant with his mother, suckling and milking her as the only care in the world. Katsuki pushes his nose into the other’s flesh, chasing a high he didn’t know he craved from his core, suckling harder and ignoring his reactions as Katsuki chased his own pleasure.
Katsuki barely registers a scarred hand combing through his blonde spiky hair, Katsuki barely registers the soft moans coming from above him, Katsuki barely registers how he’s closed his eyes and moaning echoing in his mouth as he sucks Izuku dry.
“Not, ah… not so rough, Kacchan. I don’t have any milk,” he whimpers above him.
Katsuki releases his tit with a groan, “mommy needs milk…”
