Alex walked in on me jerking off and I couldn't have been more embarrassed! But she really didn't mind, in fact she seemed pretty interested.. After we talked, sis wanted me to take some sexy pictures of her.. She pulls her top down and lets me feel her natural perky tits! "Now let me take care of you!" Alex gets down on her knees in front of me, and pulls my shorts off. My hard cock popped right out and my sister didn't waste any time. I watch her as she sucks on the head of my cock, teasing me with her tongue. It feels so good as she plays with my balls and licks up the shaft of my cock. She climbs on top of me and rides my rock hard cock! My horny sister bounces her perfect ass up and down, getting as much pleasure out of me as possible. I love watching sis enjoy my cock, so I bend her over and pound her tight cunt doggystyle! Right when I was about to cum, we heard our mom calling for us from the other room!
