Sexy Redhead Told To Gag Herself By Dominant Girl

I'm getting ready for a night out flirting with the boys when my big step-sister enters my room. She's holding a video camera filming me as I'm sitting there putting on red lipstick in front of the mirror. The only problem is, the lipstick is my step-sister's and I'm using it without her permission. Step-Sis got me on tape and there's no way I'll be able to talk my way out of this. She gets so mad at me for taking her lipstick without asking her first and tells me to give it to her. From the past, I've learned never to argue with my step-sister because she's so dominant and always gets her will, so I hand her the lipstick without putting up a fight. Step-Sis tells me that now she's caught me on film she might as well go tell step-mom that I'm a little thief and that I'm flirting with boys. I plead with step-sis not to tell step-mom because that would definitely get me grounded for at least a week and I don't like being grounded...
