Need help finding a particular story

[Boaman9]

I really liked this one story, it would be great if someone could help me find it.

Basically it was about a guy and his step-sister, the girls mom and the guys dad ended up hooking up and getting married, and the guy overheard them having sex, and the girl heard it too and said mom's only that happy when she had great sex.

Anyway they end up practicing on eachother and stuff.

Anyone know the story?

The description's too vague, man. Go to story search and hit advanced, hit Incest and some specific search terms. Sounds like one of TryAnything's stories, but his usually involve real family members.
