wow, sounds like h is into incest.
OP you should run...run fast

Well if I did that I would be fine since my girlfriend has the same name as my sister.

He's probably not even referring to his sister. Brittany is a common name.

I can see why their is a pepper at the start.

awe gross incest

Today, i jumped on FML and read this fake post about a girls bf yelling out his sisters name during sex. It was pretty fucking stupid.

Why do you assume it's fake?
There's no way to know for sure either way, but why just assume it's fake?

It's possible that he has an attraction to his sister
But Brittany is a pretty popular name (I'm pretty sure I know at least 8 different girls named Brittany, myself), so it's also possible there's another Brittany in the picture
