Mary was trapped. The black vacbed she was in was meant to only hold her for an hour. The vibrator on her pussy was meant to tease her. She wanted to be teased for an hour and released.

But she knew, even though she couldn't see through the black rubber, that it had been hours since she was trapped. She squirmed, moaning, trying to get freed, trying to cum!

SHe heard footsteps and thought her roommate was home. She felt her friend turn the vibrator up to max, bringing Mary to an orgasm.

Mary came, thinking she was freed. until tape was placed over her breathing hole.
