Help cannot remember the name of the story

[fasax]

Hey

Maybe someone can help me. Trying to remember the story name but dont.

The story starts with a guy coming home unexectantly from university and finds his family having a swingers party and finds out they have had it for years but they have exluded him. There are several chapters but I only got read the first chapter and then my computer crashed and the history is gone...

Thanks in advance
