I Had sucked the cock of my step-son only once, only once. It happened when I had a discussion with my husband. But since then I have not been able to get rid of the idea of your penis by the mind. And the situation worsened when I discovered that my stepson had a girlfriend. This made me jealous. I did not want my stepson if doing. So I convinced him to stay and to help me to choose sexy underwear for her father. I just wanted to seduce him and to make him be with me. But the plan is the result better than I expected because we fucked.
