Skin slapping against skin echoes through the gym. Brunette with ponytail squats low, pussy engulfing his shaft completely, thighs quivering from the strain. Tits bounce heavy. He stands muscled and inked, hands clamped on her waist, thrusting up to meet her descent — wet sounds mix with her gasps. Close-up on the penetration, lips gripping tight. She leans into pull-up bars for leverage, ass flexing. Switches to bent over, cock slamming deep amid grunts and creaking equipment. Relentless rhythm builds to shuddering finish.
