#345313 - This continued alot almost daily even though my siser was 16 and could beat me up i made her do it cause i didnt like the sound of me becoming one of those everyday boyz who jacks off everyday for sexual enjoyment i wanted to tell my friens i could get sex whenever i wanted. This continued untill she cummed and even sometimes when she still climaxes and i havent i'd make her climax again untill i have. I thought i was gunna fuck my sister untill she moved a way untill on the day she had to leave for college on her last day home we had sex one last time for 3 hours straight we were so worked up into it we didnt even notice that my parents were throwing a surprise graduation party for my sister and they walked up into the room while we were stil having sex and i had just cummed on my sister face.
