Chapter Text
--
The first time Stiles catches Derek masturbating, he enters Derek’s room without knocking and just stares at Derek lying on his bed naked, one hand curled around his cock, the other under him, his fingers in his hole.
Stiles blinks, blushes, and backs out with a quiet, “Sorry.” Then he knocks on the door. “Can I help?” he asks. Derek sighs, fighting the burn of embarrassment as he wipes his lube-covered hands on his discarded t-shirt. “Please?” Stiles begs. “I’d really like to see you pleasure yourself, to see what you like.”
“We’ve never been naked with each other,” Derek says. “I…Maybe?” He pauses, thinks about that answer, about his still-hard cock, his empty hole, about Stiles’ hands, Stiles’ smile.
“Maybe?” Stiles prompts, and Derek makes up his mind. He crosses to the door and throws it open, stepping back as Stiles falls into the room. “Maybe—yes?” he says, softly, once he’s regained his feet.
“Yes,” Derek says. He grabs Stiles’ hand, folds their fingers together, and leads him to the bed. They settle quickly, Stiles sitting against the headboard while Derek kneels over his lap.
“I like,” Derek mumbles, tracing the lines on Stiles’ palm. “Please?” He reaches for the container of lube on the bedside table, popping the cap and squirting a healthy amount onto Stiles’ fingers. Stiles inhales sharply, letting Derek guide his hand between his legs, skimming his cock and touching his hole.
It’s still loosened from his interrupted fingering, and slowly, together, they work one and then two of Stiles’ fingers into him.
Derek sighs in relief, sinking down so his bare knees bracket Stiles’ jean-clad thighs. He braces his hands by Stiles’ head. He raises himself and then sits, still moving slowly. He hisses at the burn, raising and lowering himself with gradually increasing speed.
“So beautiful,” Stiles murmurs, crooking his fingers and stroking deeper. Derek whimpers when he brushes over something that makes him feel like he has to pee.
“Like that, babe?” Stiles says, smugly, smashing their mouths together while he rubs that spot until Derek pulls away, sobbing at the sensation. It’s then he notices the semen covering Stiles.
“I…?” he hiccups.
“You did,” Stiles says, smiling. “And you were perfect.”
