Stiles says he'll stay, and that's comfort that blooms in his chest, voiced in the rumble of a slow exhale. There's a hint of a smile that curls at his lips as Stiles slides down over him, collapsing on top of Derek's body. He shifts a little, curling in toward Stiles and wrapping an arm against the teenager. Making sure he can't leave. He just wants to keep him, wants him to stay, even if he's not exactly prepared to look at that desire too closely. It's not recent, so much as tonight just sparked off everything he's been ignoring for the past year. Ignoring it was easier.

"I want you here," Derek breathes in a huff, words muffled as he nuzzles into Stiles' skin. He can deal with all of this in the morning. What happened, how he feels, what happened and that he wants to do it again, that he wants sex, wants to feel Stiles against him, and the fact that he's staying. The fact that his loft is nearly bone-bare, and he's honestly lucky he left the comforter on the bed. He pulls Stiles close, breathing in the way their scents mingle together as pleasure curls through his body.
