The redhead's heart races as she's secured to the weightlifting machine, her muscles taut and ready. A gloved hand explores her body, tracing the curves of her muscles, dipping into the valley of her small tits. She gasps as a vibrator is pressed against her clit, the sensation sending shockwaves through her body. She bucks against her restraints, her muscles tensing and relaxing in a futile attempt to escape her torment. Her moans echo through the empty gym, a symphony of pleasure and pain.
