Sirius had never slept next to almost anyone but James or his brother. In all his years of debauchery, he’d never let anyone stay overnight at his flat and certainly would never have deigned to sleep in anyone else’s bed if he could help it, save for a few nights when he overindulged and fell asleep before he could make a better decision. Even then, he’d always slip out well before morning without a second look or an ounce of guilt or regret.
