Sister Rubs

So I am an 19-year-old male and I just wanted to share some of the things I've seen my sister do over the years. She's 2 years younger than me and is really good-looking with such nice tits. Over the years I have seen her do many things with the remote. I would be on the computer and really strain myself to look down into the tv room where she would be rubbing the remote on her pussy hard and fast. I have seen her come a couple of times. She has her legs stretched out on to the coffee table spread open and just goes to town with the remote. Sometimes whe would use her middle finger and rub up and down as fast as she could. A couple of times she has caught me looking down into the tv room. One time I got out of the shower and sat down at the computer real quick to check something, and caught her grinding on a pillow naked, but under a blanket. That was extremely fucking hot. I just beat off onto my towel and went into my room. Another time we had a futon in the middle of the tv room, and she was in her pajama pants grinding her pussy onto the edge of the futon while with the other hand pulling on her thong and pulling it back and forth. I always just wanted to go down there and just rub her.
