We were always close. Never felt awkward her walking into my room and stuff. So guess it made it easier. I knew for a long time she loved glancing at my cock when she could because I overheard her telling her friend over the phone. I was honestly just waiting for a good time to approach. One summer dad's working and she's out back sunbathing. She called into my room and said she's gonna bathe topless that if any visitors called give her a heads up.

I waited a little and was a horny 18 year old so decided to go look out a window at her tits and wank. Well when I looked out she was rubbing the clit off herself. That was the moment. Got undressed walked out and told her "I have to" while I'm throwing her legs over my shoulder and starting absolutely fucking pounding her. She loved it.

Still the best fuck I've ever had hands down. I miss her.
