"Fuck, you are!" Stiles said as he grabbed Isaac's hips so he had control over how fast and far Isaac would take his cock. He could feel how wet Isaac was and Stiles had no doubt that Derek already had the slave once this morning. The thought of his and Derek's come mixing together inside of Isaac made Stiles grin.
"Derek has already had you, you little slut," Stiles said as he rolled his hips up so just the head of his cock moved in and out of Isaac. Stiles' hands on the werewolf's hips wouldn't let him have more.
