The gym's silence is shattered by the sound of the door creaking open. In walks a maintenance man, eyes widening at the sight of the petite teen masturbating fervently on the mat. She freezes, then grins, inviting him closer. He hesitates, but her tight, toned body and eager eyes prove too tempting. Dropping his toolkit, he approaches, his hard cock straining against his overalls. She pushes him onto the mat, straddling him, her tiny hand wrapping around his thick shaft. She guides him inside her, gasping at his size, then rides him hard, her tight pussy gripping him as she moans, "Fuck me like your little gym slut."
