I lost a bet to my sister about a month ago. I bet stupidly because I was sure I could win. I made the bet that the loser had to my sisters black lac french knickers on their head while they did the winner's share of the chores and do three things the winner told them.

The first my sister told me to do was obvious strip totally naked including the socks.

The second was dance to the soundtrack of High School Musical and if I did a step my sister thought was wrong she had the freedom to swat my ass with her tennis racket.

The third was be a naked slave to her and friends at her next sleepover.

Anyone else have a similar experience
