Sister chair white underwear bondage

My stupid sister had to babysit me and my friends. We were all watching some dumb movie that had some girl getting tied up. "That's so lame" Lee rolled her eyes. "I'd get free in a second."

I said prove it. She gave us a dirty look and went upstairs, but she came back with lots of rope. She also wore a skirt and heels now, and when we made her straddle a chair her skirt rode up over her stockings.

We stripped her to her underwear and tied her to the chair. You got one second to get free, I said. We laughed as she tried to get free, but I knew Justin and Kyle had serious boners.

I said I know where she keeps her vibrators. When I got back, they were feeling Lee up and she was moaning into a ball-gag. When I turned on the vibrator, she squealed like she planned this all along. What a slutty sis.
