The night had been tiring, but Isaac could still feel a small crackle of left over energy inside him. Even after Derek and Laura fell asleep, he knew that he would most likely spend a few hours, wrapped up between them, watching them sleep. If Derek wanted to be left alone, he was doing a good job at mixing his signals. Isaac's back bowed, as his Master's teeth ran over his skin.
His head turned slightly, when Laura asked after Stiles. He had hardly spend any time at all with the human, and wasn't sure what he thought of the idea. Would he press in between Derek and Isaac, parting the sweet physical contact that Isaac was enjoying? Even after the time in the woods, he could still smell traces of the slave on Derek.
