Hiya girls!

I'm looking for a story that I read some time ago that I just loved and cant seem to find it.
I dont recall the name of the title...thought you all could help me. I may have read it before Fictionmania crashed...

It was about two brothers. The oldest was caught masterbating and ended up in some program,
thanks to mom, that changed him into a young woman and married to some jock from high school. Well, the two come for a visit w the family..Christmas or something..

During the story, the younger brother becomes curious of his 'sisters'bra and pany she purposely left on thehamper in the bathroom. Little bro keeps putting these on and watching his sister getting screwed by her man in an adjoining bathroom. He keeps this up and despite warnings of his sister, he gets caught by mom. And he ends up like big sister.

Does anyone know of this 3 part series??

Thanks!
Trish
