My stepsister always made me very horny. I admit it. It's a compulsion I have to watch her sleep and touch my cock while I imagine fucking her. One day I couldn't take it anymore and started fondling her. Squeezing the perfect ass she has while watching her completely naked body made my cock so hard! When she woke up I was scared, but I was able to convince her to keep a secret. A very well kept secret of ours!
