Hell, Stiles could wear a turtle neck and it would probably be visible right above the collar. Not that Derek minded, and he didn't mind the thought of Stiles showing it off either, as he knew he would show off his own once he had it.
He couldn't wait to have it.
"I'll reward you later for your good behavior," he called out as he watched His little naked cheeks heading for the bedroom. It was a shame to cover that ass up, but he knew it was for the better if he did. It would make the conversation with Scott so much easier. And it was already bound to be stressful without them adding their easy nakedness to it.
A gentle make out session was definitely fine. It dind't have the urgency they normally had and it was -- it was good to do something with their clothes on. Derek loved their naked fun times, but it was good to do this too, his hands on Stiles' clothed hips while they traded deep kisses back and forth.
He liked kissing.
He really liked kissing Stiles.
Even though he could smell that slight spice, it wasn't as strong as it got when Stiles was fully aroused. Giving him a good boy kiss, Derek got off the couch first to answer the door. Part of him wanted to growl Scott into submission until he accepted their status of mates. A larger, more likely to think side realized how bad an idea it would be.
Better to treat him like a little mini-John.
Opening the door, Derek stepped out into the hallway to meet Scott, but left it cracked behind him.
"Hey," he started.
Scott rocked back on his heels, eyes narrowing as though he had expected to see Stiles first. "Where's Stiles?"
"Inside," Derek answered. "He's fine, I just wanted to talk with you for a few minutes. Nothing bad. We both care a lot about him, and I realize you might have some things you want to ask me," Derek said carefully. "I'm not keeping you from him, you can poke your head in if you want, but I thought this might be more of a neutral territory than inside."
