Looking for a story...

about a daughter who has a big playhouse in the back yard and a mother who watches from an upstairs window. In an early scene the daughter is playing with two boys (truth or dare I think) and winds up being stripped, blindfolded and tied up against the wall. The boys sneak out a back way when they here the mother coming. But instead of releasing the daughter, the mother places a pillow case over her head and has a good time playing with her.

In a later scene, the daughter has to suck the two boys off, but doesn't like to swallow. Later in the story she discovers that her mother has been watching and it was her mother who played with her the first time. They have a discussion about swallowing cum and mother can't understand why the daughter doesn't like to. The next time the daughter has to suck the guys off, she carries a mouthful of cum back into the house and deposits it into her mother's mouth thru a deep french kiss.

Does anyone know the name and/or author of this story?

Thanks,

Yorts
