You cant go to bed due to a very persistent boner so you go to your stepmom to ask for help. Everything she suggest to you you have already tried. She decides to get hands on herself to help fix your problem. Shes a bit shocked by your size and wonders if that one of the reasons why masturbation hasnt helped. She takes your dick into her hand and mouth milking you until you let out a big load. Hopefully now you should be able to rest peacefully.
