Well there went that. Stiles was still pissed and was afraid to yell at a wolf. The wolf on the other hand flatten it's ears and set it's head down, whining. It did not like for its mate to be be mad at him. He tried to nuzzle the boy's hand opening to get petted again.
As for Derek, he sighed inwardly. How was he going to explain to Stiles the he was scared shirtless. No one is prepared for their first mating. No one has a sign above their head to say who their mate will be. Yes Derek did not handle that well, so he would tell the boy soon. But that didn't mean that everything would be fine.
