"You're not vibrating," Derek replies lazily, words rolling off of his tongue. He sort of feels like he's moving through molasses and he's not entirely sure that he likes it. Usually he's moving so fast, even when he's sitting still. His heart beats fast, his blood pumps fast, and now he feels sort of muted and slow. Hazy.

"I feel heavy," he says after awhile, plucking at his shirt. "My clothes feel heavy."

Without thinking much of it, he pulls off his shirt and tosses it aside. The air feels good against his skin, and suddenly he thinks about how good it would feel to just lay in this patch of sunlight. "Hey guys, I'm gonna shift. Don't freak out."

Soon enough, his clothes are gone and Derek shifts into a hulking black wolf, shaking out his thick black fur. It's already getting thicker in preparation for winter, and Derek leans down to stretch out his legs before jumping back on the deck chair between Dean's legs, huffing as he drops his head into Dean's lap and sprawls out.

Yeah, this is good. He feels lazy and safe, and he revels in it.
