Eva, the mistress, commands Martin to assume the position. His cute form trembles as she lubes up her strapon and presses it against his virgin asshole. She pushes in, inch by inch, Martin gasping at the intense, pleasurable invasion. Eva's skilled thrusts soon have Martin begging for more, his sissy moans echoing through the room. She obliges, picking up speed, her hands roaming his body, pinching his nipples, slapping his ass. Martin's orgasm builds, his cock rock hard, pre-cum dripping. Eva watches, her own pleasure mounting, as Martin's body convulses in a powerful, prostate-driven release.
