I always thought my step sister Anya is a good girl. Till the day when me and my friend found a box under her bed with weird stuff inside. We found a whip, a collar and other kinky things like mouth ball gag. We were literally shocked and at that moment she came to bedroom. We had some fun over her first and then we both with my friend felt strong erection in jeans. Anya was pretty impressed seeing this and agreed to get this party started even before we asked..
