I read the story on this site, the chapters could be broken down something like:
Part 1 at the start of summer break a male goes home finds out he will have to spend two weeks with his step sister who wasn't nice to him and spent most of her life at a boarding school. She apologizes for her behavior and seduces him.
Part 2 The step siblings' younger half sister arrives and the step sister leads a seduction of her.
Part 3 All three seduce mom and find out parents are swingers.
Part 4 Brother and half sister return to college for the fall, awaiting the other sister to transfer at end of semester. While there brother starts to work his way through the cheerleader team which his sister is on. The cheer leading coach discovered them and blackmailed them with the help or at least consent of the university dean.
I tried finding it via the search but after an hour I have given up, i don't remember the correct key words it seems, any help will be appreciated.
