it's a bday smooch~

(2/2)

All the while Bakugou is gently gnawing on Kirishima’s hardened shoulder, half scenting him and half trying to soothe his aching teeth, not paying attention to a word coming out of his mate’s mouth because he knows damn well Eijirou does the same thing before he’s in rut.

Kirishima is stuck for the rest of the afternoon in Bakugou’s bed getting scented and trying to get it through Katsuki’s thick skull that he doesn’t want another mate and that he’s being dumb picking fights with classmates.

In his head the green haired alpha is over stepping and trying to, in some way, prove how he’s a better alpha than Katsuki (which he’s not, he’s very happy with his own mate), after that Bakugou’s pack tries to keep the two of them separated before it ends in an actual fight.

and get extremely territorial over their pack mates and especially over the omegas. Bakugou, before his rut, 100% lashes out at Deku, teeth bared and all, over him asking Kirishima to take notes on one of his new moves or something.
