Bound and gagged over big stepsister's shoulder!

When my tiny little stepsister Piper tells me she got her belly button pierced I knew step-mom wouldn't like it but I also knew stepmom would do nothing to punish Piper for it. Piper has always been stepmom's favorite girl and unlike me, she has never been punished for doing anything wrong in her life. So I decided to take matters into my own hands and give Piper the punishment she deserves. I tape her hands and ankles up, stuff a pair of panties in her mouth and wrap duct tape around her head like step-mom used to do to me when I've been a bad girl. Then I lift her up and carry her over my shoulder with her ass in the air while she screams and kicks! I tell her what a bad girl she is and checks out what kind of underwear she's wearing under her tight jeans. A thong?! Piper must be fucking her boyfriend and big step-sis certainly does not approve of that at all! I give her a wild and fast spinning around over my shoulder and put her down to take off her jeans and expose her perky tits!
