In a dimly lit dungeon, a bi-sexual woman is strapped to a St. Andrew's cross, her body glistening with sweat and anticipation. Her femdom mistress, a stern woman with a sadistic streak, teases her with a giant, fat dick strapped to a harness. She pushes it against the woman's lips, making her drool and beg for it. The mistress laughs, relishing her pet's humiliation. She rubs the dick all over the woman's body, paying special attention to her clit, making her squirm and moan. Then, she slides the dick into her pussy, fucking her hard and deep, making her scream with pleasure and pain.
