kacchan walking in on deku wearing this & he's instantly aroused- deku looks so fucking delectable he could cum right there.

but ofc deku is so embarrassed at being caught that he doesn't see how affected kacchan is, so through tears he's begging

"p-please! please kacchan, d-don't tell anyone! i'll do anything you want."

& kacchan isn't stupid so with a feral grin, he palms the front of his own pants lewdly, "anything, eh? why don't you come closer?"

& deku does- drops to his knees like a good boy & with

teary, bashful eyes & a shy tongue, deku sucks kacchan's soul out through his dick. kacchan sees how far he can push & that's how he gets deku riding him & cumming in his lap.

afterward, he teases deku by saying he wouldn't have told anyway; he doesn't want anyone else to

see his nerd in such sexy underwear.

"wear it under your uniform for me tomorrow?" kacchan requests, nipping at deku's jaw & snapping one of the garter straps.
