Berty, a prisoner in his own body, is confined to a chastity device, his cock kept in check, his desires simmering. But today, he's had enough. With a wicked smile, he retrieves a bottle of lube from his nightstand, slicking up his fingers. He parts his cheeks, baring his hole to the cool air, and pushes in, gasping at the sudden fullness. His mind races, his body responds, and he fucks himself with increasing fervor. His other hand works the lock on his cage, desperate for release. With a final, frustrated cry, the lock gives way, and Berty's cock pops free. He strokes it roughly, his ass clenching around his fingers, his body tensing as he hurtles towards orgasm. He cums hard, his load shooting out, painting the floor with his pent-up desire. His body shakes with the force of his release, Berty finally free, if only for a moment.
