Master Trainer's Command No. 60: Restrained in an Abandoned House with a Vibrator and Fuck Machine

I was brought to an abandoned house. There, I was bound with ropes to expose my pussy. Unable to move, the switch for the vibrator inside my pussy was flipped on. “How long do you think you can endure?” Those words from the Trainer reached my ears. There was an unspoken rule: I must not come without permission in front of the Trainer. I had no choice but to endure the vibrator, fighting not to come.
