maybe there's a porno mag squeezed into the bookshelf that he can't not look at and bakugou is all cool about it and pulls it out for them to look through. and kirishima hopes so fucking bad that he gets the chance to ask a dumb question about sex that bakugou can answer, preferably by showing him

just imagine!! he'd be living his best life coming over for movie night. it probably smells like axe body spray in there and a couple of booby pro hero posters hang on the wall above the bed for kirishima to try and fail to ignore
