Bound and gagged, the helpless maiden is at the mercy of her dominant mistress. The room echoes with the snap of the whip and the creak of the ropes as the mistress teases her bound pet with a monstrous strapon. The dildo, larger than any she's seen, glistens with lube, ready to claim her. The mistress rubs it against the maiden's wet slit, making her squirm and moan through her gag. Slowly, she pushes the massive head inside, stretching the maiden's tight pussy. The mistress grins, relishing the sight of her pet impaled on the giant dildo, fucking her mercilessly until she cums.
