Looking for the title of a possibly deleted story involving a girl cheating on her boyfriend's roommate who is a nerd

[throwaway1]

I can't remember the title at all, does anyone remember it from the description? The story had a lot of GIFs in it as well.

The girl had a lot of sex with her boyfriend as well as her roommate. At some point I think she involves her other girl friend as well.

Thanks in advance!
