In a simple, unadorned room, a magrinha, as she's known, climbs atop her lover, facing away, her long, dark hair cascading down her back. She grips his thighs, steadying herself as she starts to ride, her ass cheeks clenching with each movement. Her partner's hands roam, squeezing her breasts, pinching her nipples, as she picks up the pace, chasing her orgasm.
