Sirius Black would so have nipple piercings.
And he would whine like a bitch for 2 weeks after as they healed. He would take out his anger on Remus as if he had pinned him down and stuck the needle in himself. Every time Remus would accidentally lean back against him to hard (which sometimes he did on purpose just to rile Sirius up) Sirius would immediately push him away with curses on his tongue, “Fuck! Moony how many times do i need to tell you!”. And Remus would simply laugh and pepper kisses on his face, apologies pouring out of each press, because Sirius Black is the most dramatic man on earth and Remus figured out a long time ago that, that was the price to pay to have him. “Stop being a bitch and kiss me, dickhead”, Remus would mumble as Sirius begins to loosen up, huffing and accepting defeat (only with Remus though, only ever with Remus.)
