Cuddling son makes him hard

Dearest Suzanne, I hope this letter finds you well. We've shared so much since we grew up I figured you would be the best one to confess my sins to. Things have gotten pretty crazy with my biological clock lately and I don't know where to turn. I'm almost ashamed to admit what I'm about to tell you it's just theres no one else I trust but you. My son came home from college the other day and I went into his room to welcome him home. I laid down to cuddle with him and before I knew it he had a raging hard-on. Before I could stop myself I grabbed it and told him not to tell his father. He was so hard I couldn't stop myself and soon we were making love on his bed. My son pounded me so much harder than his dad it was almost a shame when he exploded inside me. That brought me back to reality pretty quick though, what would I say if my son knocked me up? Your Friend Gina.
