My stepmother, my father's new wife, is a young, attractive woman with a great figure—especially her big tits. One day, I accidentally run into her as she steps out of the bath. The towel drops, revealing her crotch, and to my shock, there's a huge cock. I realize in that moment she's a newhalf. At first, I feel uneasy about her being a trans woman, but I can't resist her aggressive seduction, and eventually end up having incestuous sex with my stepmother.
