Her gym pants stretch taut over her firm ass, the outline of the plug visible as she moves. She's aware of the eyes on her, the workout making her sweat, dampening her hairy armpits. She inches her pants up, revealing more of her toned thighs, her pussy's scent mingling with the sweat and gym smell. She's close to being caught, but she can't stop, her body aching for release. The plug fills her, her pussy throbbing with need, her workout becoming a public display of her kinky secret.
