Despite what everyone thinks, Izuku is damn near silent during sex. He's so focused on the task infront of him that he goes nonverbal, snapping his hips into whichever member of the class that had stumbled into his bedroom that night.

It didn't matter who, because he would do everything in his power to make them cum.

Tonight Katsuki clings to him and moans his name like a prayer, gasps like Izuku's cock is the most shocking thing he's ever encountered.

Deku is fucking him like he's going to be graded on it. Every thrust seems to hit Katsuki's P-spot, or close enough to it that he groans and shakes despite his best efforts.

"fuck, fuck! don't stop, don't fucking stop."

Izuku wouldn't think of it.

"Deku, fuck, gonna cum."

Izuku didn't say anything, just hummed "mmhm" and kept his pace steady. Fucking Katsuki through another leg shaking orgasm, it was amazing, but it wasn't the best part.

The best part was when Izuku would cum, his hips would start to lose their rythm and he finally regained his voice.

"fuck, gonna cum inside you."

Those five words drove Katsuki so far over the edge he felt like he was going to black out.

He held Izuku's cheek in his palm and brought their foreheads together as he whispered,

"cum inside me, fuck, please, fill me up."

Izuku kissed him deeply, moaning into Katsuki's open mouth as cum shot out of him and deep into his partner with every thrust.

His body shook, his hips trembled, and every dirty thought seemed to fall out of him all at once.

"Fucking perfect, such a good whore, take it, you can take my cock, all of it. Every fucking inch. Damn baby, so good, you can take everything I have to give. Fuck. Take it all"

Katsuki was more than happy to oblige.
