Leaning back on the thin mattress with her panties pushed aside, the silver-haired granny works a thick vibrator between her thighs. Her free hand grips the dildo, pushing it deep as her hips jerk off the bed. Gray hair spills across the pillow while her other hand clutches the bars of her cell, body trembling with each pulse of pleasure. The vibrator hums nonstop as her thighs shake, thighs slick with arousal. Stockings bunch at her ankles while she rides out the orgasm, breath coming in sharp gasps before she collapses against the mattress.
