During a break from a particularly harsh BDSM session with Master, I am permitted to masturbate while he steps out onto the balcony for a cigarette. I am permitted to masturbate on one condition: I cannot cum until he tells me I may. I beg and plead with him to let me, and he nods through the window, giving me permission the first time. He comes inside to watch the second time, and helps me along while I beg even more. Finally he gives me permission before he decides that break is over with!!!
