It almost felt like Isaac was listening to Stiles and Derek talk about him, from somewhere else. His body was so focussed on please, that it could barely take in anything else. Even still, he took in enough to be pleased when his Master spoke about him. He was shameless, and a whore, and all of the other things he was called by the older werewolf. But he was also proud of being all of those things, know that he knew they were things that would be treasured.
Isaac rolled his hips back, signalling his pleasure at the addition of another finger. He could take so much more, but he would take it at whatever pace Stiles and his Master wanted.
