The reaction he got from Derek was far better than anything he could have imagined. And Stiles had imagined. He loved the noises, but he also loved more the way that Derek rocked back onto him. He would have loved to do it properly, he would love to bring Derek to orgasm this way, maybe jerk him off too, maybe slide his fingers into Derek beside his tongue-
But there wasn’t time right now.
He smiled at his mate flopped over his legs, running his fingers through Derek’s hair.
“I really like- I like-“ he started, trying to work out how to word how he felt. How he loved that his alpha would be happy to give himself to Stiles the way he was. He loved that Derek was happy to drape himself over Stiles and let himself be petted and praised. He was sure that other alphas would be scornful of Derek’s supplication to him. But they weren’t like that. They didn’t buy into those stereotypes.
“Yeah, I knew you were like all those other knot heads,” Stiles teased, despite what he’d just been thinking. “Just ruled by your dick every time you see a fertile omega-“
It was for the best that they showered on their own. It took a while for Stiles to get used to the feeling of the plug inside him when he was standing up, the way it kind of rugged at his rim as he moved, and brushed against his prostate- he had to shower quickly before he got too distracted.
He’d packed something nice to wear for their first actual date, even if he wasn’t going to be in it too long. A Black tshirt, plum shirt, and tight black jeans. Tight. He was sure that Derek would appreciate it and yeah, he really wanted to tease his mate through dinner. He wanted to get Derek worked up. He wanted his mate to be desperate to get him home, to strip him and bend him over, pull out the plug- fuck, Stiles was going to be so wet. Derek would love it. And Stiles was preening at the thought.
