Regulus dragging Sirius to a club and Sirius meeting Barty who is manspreading on one of the couches in the backrooms, smoking and demanding all the attention in the room. Demanding Sirius' attention too.
Everyone is obsessed with him, it's so clear. They surround him, taking in every word he says but Barty is bored. He sees the same people every night, he's slept with over half of them, he needs something different. So when Sirius walks in, looking so eager, so hot, Barty is transfixed.
Sirius can already imagine himself under Barty, ready to receive anything Barty is willing to offer, ready to carve his initials into his heart if he has to.
And Barty so willingly hands him the knife.
