Casey Calvert, the eager brunette trainee, is put through her paces in this intense BDSM session. She's made to carry heavy weights, her mouth stuffed with a thick gag, as she's spanked and toyed with. A vibrating dildo gets her lubricated, only for the trainer to zip her up, denying her relief. She's reduced to a moaning, submissive slave, her bizarre training pushing her limits.
