Lets face it. He wants to watch your tight pussy get fucked by bbc. He wants to see you really orgasm. Shake from being fucked by something so big. He could never make you shake with his tiny thing. He could never make you shake from being fucked so deep.
His tiny clit is useless. He should be only one who takes any cum from that cock. And by that I mean self facials.
Rule 6: Regular self-facials if he asks to be let out of chastity.
