Silver hair splayed across the pillow, the older woman straps her trembling feet into the machine, her pussy already glistening as it pistons in and out. Every stroke makes her belly jump, her tits bouncing loose with each deep grind. Fingers claw at the sheets while her mouth falls open, no sound escaping but the wet slap of plastic against slick flesh. The machine doesn’t stop, doesn’t care — just pounds her until her thighs start to quiver. Her silver brows knit tight, her whole body tensing as the orgasm rips through her, her back arching off the bed.
