Cuck is chained into position - ankles and wrist, and he is to wait in that position while Mistress goes on her date. Immobilized he is ask to suck and gag on Mistresses big dick. She wants him well trained for servicing her boyfriends when she brings them home. She wants to stretch that hole of a mouth of his until it's gagging him and he can't breath. It's going to be cock for dinner and cum for dessert.
