Isaac had never understood how Stiles could sleep in so late. Every time he tried, all he could do was stare at the ceiling and think of all the things he could be doing. Normally Stiles didn't have a lot to do, but Derek had increased his training sessions recently, and Isaac knew that if the boy didn't appear soon, he would be late. In Isaac's opinion, slaves did best when they looked out for each other, which put him at Stiles' door.
"Stiles?" he said from outside the door, forgetting that he wouldn't be heard by normal human ears. When there was no response, he cracked the door open and slipped inside. It didn't take more than a second for the scent of Stiles' arousal to hit the werewolf, and he turned to catch an eyeful of the human working his cock over with his hand. Isaac pulled in a gasp of air, shocked and aroused by what he saw.
