The gym girl's heart races as she locks the door, her eyes fixed on the intimidating dildo. She strips, her fit body glistening with sweat, and slips on a pair of socks. Spreading her legs wide, she inserts an anal plug, her pussy clenching at the double penetration. She lubes up the massive dildo, her hands shaking with anticipation. She mounts it, her pussy stretching to accommodate its size. She rides it, her body bouncing, her huge tits jiggling, until she's a dripping mess. She switches to hands and knees, her ass slapping against the dildo, her pussy convulsing as she reaches a jelly-like orgasm, her body shaking with the intensity of her release.
