In a private, kinky session, a sissy bound in a chastity cage is subjected to a relentless prostate massage. A skilled hand works her male G-spot, sending jolts of pleasure through her body. She's ordered to keep her hands behind her back, her body writhing as she fights the urge to touch herself. The pressure builds, her cock leaking copious amounts of precum, her ass clenching around a thick, vibrating dildo. With a final, intense thrust, she's pushed over the edge, her orgasm ripping through her, her body convulsing as she cums hands-free, her juices coating the machine and her belly.
