uthor's notes:
Originally the mom was supposed to get madly turned on by hearing (and watching) her son with her friends, but actually not be into doing him herself, but by popular request at least the idea has been planted in Brad's head now.
For a full incest story I would have preferred to get the dad out of the picture, but I don't feel I can kill him off now. I am working on another solution though.
The story actually takes turns I've not foreseen myself as I develop it ;-) It's quite an exiting experience.
Negative votes are welcome, but please comment on what you don't like so I know what to improve!
