"Oh god," Stiles said softly his brain over heating from all of the sensory information he was getting. Derek was pressed against his back, his cock between Stiles' cheeks, and Isaac was laid out before him looking like he needed to be fucked badly. Stiles wasn't sure how he got into this kind of situation but in that moment he didn't care. He would think about it later.
One of Stiles' hands moved between Isaac's legs, pressing a finger against his entrance. Stiles felt it give and his finger easily slid into the werewolf. "Oh god." Closing his eyes and grateful for the cock ring Stiles slowly finger fucked Isaac. Being the fucker and not the fuckee was new to Stiles and he clearly didn't want to rush it even if the wolves did.
