With my blue latex gloves on i ask him up or down leting him to choose the speed from the vibrator and he chosed up wich is the faster speed :) without knowing so i will play with that vibrator on his cock while he kisses my ass and he gets so aroused he barely can hold the cum in but i worn him to not cum without my permission so i know he doesn't want to be punished and he knows that if he behaves he will get also pleasure . So in the end i count down and when i reach ten he cums.
