Stiles cried out when he felt Derek tense behind him and he felt the werewolf come. Derek had gone a little deeper then before but Stiles wasn't going to complain. He had liked the feel of Derek's cock stretching his hole and he wished that Derek had pushed all the way in.
But then the werewolf was playing with the plug inside of him and ordering him to his knees. Stiles was more then happy to comply. He turned and got to his knees in front of Derek. Without hesitation he took Derek's softening cock into his mouth as he started to lick and suck it clean for his Master.
