He loved the way Stiles responded to him and that little offering -- there was no way he couldn't take Stiles up on that and mouthed his throat. Nipped and sucked at the skin until it was bright red like he'd been ravished.
Well, not yet.
Teasing wasn't something he'd ever gotten to do very long with Stiles, they both needed too much. It was something that would come with time, Derek was sure, but until then, he took it where he could get it. Like now -- "Know you can," he said with a grin. "Know you want more than that too."
He knew where Stiles looked too, and could help but suck in a breath, his cock twitching within the confines of his jeans. "Love how wet you get for me," he whispered, cock pulsing again. Derek wanted out, wanted to roll his sexy mate over and pin him against the couch while he he took him again -- but he also wanted less clothes. "Take it off," he said of his shirt, uncaring where it went so long as it was gone.
As for Stiles'? He'd take care of that in a minute. Pulling his finger free, his hands ran up his back, under the borrowed shirt he was waiting, deliberately leaving a little slick trail going up his spine that Derek would clean up later because like hell he was going to let anything that tasted of his mate go to waste. The material bunched up around his forearms, and with a grin, he lifted Stiles' shirt off and tossed it on the floor next to his betas.
And though his focus wasn't on them right now, he still knew where they were and what they were doing, with Boyd's hand down the front of Erica's jeans.
