A kinky girlfriend, hungry for power, straps on her most intimidating toy and approaches her bound boyfriend. She runs the massive, veined strapon over his body, making him shiver. She traces his lips, his nipples, his cock, before pressing the head firmly against his hole. He gasps, eyes wide, as she pushes, stretching him inch by inch. She smirks, loving his vulnerability, and begins to fuck him, slow and steady, watching his face contort with pleasure and submission. She picks up speed, her hips slapping against his ass, until he's moaning, begging for release.
