Strapped into her flat chastity cage, the sissy girl's clit throbs from the clip, desperate for release. She slides a urethral toy into her slit, gasping at the unique sensation. Her body responds instinctively, grinding against the invasion, seeking more. As she edges closer, her hands remain bound, unable to touch herself. The tension builds, her breath ragged, until finally, she's rewarded with a hands-free orgasm, her body shaking as cum drips from her urethral plug.
