I'm a boy with an infinite libido who masturbates every day until my dick cums. I started living with my stepmother, who I think was a former slut and was my father's new wife. One day, I heard a strange noise coming from the second floor, so my stepmother took a peek and saw her stepson masturbating. The former slut is genuinely worried about her stepson, who never seems to cum no matter how many times he does it. If he does it with his mouth, it's not cheating... my stepmother steps in... and she takes off her panties to save her sex-crazed monster son.
