Sarah Star, a new inductee into the world of BDSM, is put through her paces by a stern mistress. She's made to feel every inch of the thick, unforgiving strap-on as it pounds into her, stretching her tight pussy. The mistress, a cruel and calculated sadist, ensures Sarah's pleasure is secondary to her own, using her like a toy for her own gratification. Sarah, despite the pain, finds herself drawn into the mistress's game, her body responding to the rough treatment with unbridled lust.
