A few weeks ago, you got caught recording your step sister's ass while she was on the treadmill. Even though you got busted, she let you keep the video. One day when you are both alone, she's sitting on the couch watching tv. You get the courage up to ask her if you can record her again. You just can't stop thinking about her ass and need more of it. She says no and then you convince her with money. She agrees and gives you a really good show!
