Re: 15th
Stiles jumped, gasping when he felt Derek's warm mouth on his now fairly naked balls. He rocked for a moment because it had felt good but he caught himself and came to a halt. He clenched his fists and let out a frustrated noise which was aimed more at himself than Derek because he shouldn't be reacting like he was.
There was a low groan from Stiles, from the back of his throat, when he felt the oil being drizzled over his back entrance and he couldn't stop his mind from thinking of Derek fucking him. God he wanted it to happen again so badly.
"There too?" Stiles complained though his voice didn't have much anger to it, more arousal as he stayed still for Derek.
