Looking for a story, Geek turns to stud.

[Jamespowel]

Hi so a while back i read a story and i just got back to wanting to read it again but i dont remember the titel or the author.

All I remeber is this, The story begins with the main character being a geek or something like that, and the story goes on until he leaves for the whole summer and comes back a stud and fucks his sister mother and best friends mom.

I think there was a woman who came back with him from his summor vacation.
Hope this is enough information.
