Spotters watch as muscles flex and bodies tense

Strapped into a harness, the eager gym-goer hoists heavy weights, her legs trembling with exertion. As she descends, her glistening skin stretches taut over contracting muscles, a sight that sends pulses of lust through the spotters' veins. They watch, entranced, as her quivering thighs and clenching ass hint at the pleasure she's denying herself. As she finishes her set, one spotter steps in, his hands sliding over her slick body, feeling the heat radiating from her core.
