I can not help it, but my big step sister is so fine. I cant stop looking at her huge ass. I know she sees me looking at her. I walk in the house today and find my hot step sister bent over wearing a short mini skirt and sexy thong. I stop to stare, but only this time she catches me and sees my hard on. She teases me as usual, but this time, I think she is turned on. She shows me her ass and her pussy, then tells me to show her what a big boy I am.. now is my chance
