Scott- as close together as possible, dead centre in the middle of the bed. You're both snorers, but you're used to it.
Stiles- facing each other, a few centimetres apart. Neither of you snore, so it's rather peaceful, even with eye contact when you wake up.
Derek- you curl up to him, you're head on his chest. He snores rather loudly, but you don't. It's a comfort to know he's there, and I've, though.
Jackson- after you guys have had sex, he usually falls asleep right next to you, still inside you sometimes. When he's fallen asleep, his breathing even, you snuggle back against him, falling asleep yourself.
Isaac- spooning. You face away from him, his arms wrapped around you, face against your neck. He breathes softly in his sleep, which is cute.
