When my mother got divorced from my father she stayed alone with me for about 5 years and during that time we started to have sex. Then my mother started dating a guy that later became my step-father and never suspected about anything. Sometimes we get careless like this time we were in the garden, we've eard someone at the gate and thought it was my step-father but it was only the mailman putting the mail in the mailbox, mom got scared but she didn't let go my cock for a minute...
