Bound in chastity, our sissy is desperate for release. Teasingly, the machine probes his ass, making his cock throb painfully against its cage. With each thrust, his prostate hums with pleasure, his legs trembling as he's denied the chance to touch himself. The machine's relentless rhythm drives him closer to the edge, his body tensing as he finally succumbs to a hands-free orgasm, his cum spilling onto the floor, his legs shaking with the force of his release.
