[SCENE REQUEST] need help finding a porn movie

[dlance]

I saw this movie a few years ago and now I can't find it. It is a French full movie. This girl takes a job is a sex shop and the owner/manager has her wear skimpy outfit. On her shift, she spies on a customer who is watching a porn in the back and is jerkin off - she joins him. In another scene, she invites her roommate and her boyfriend to the shop, and they end -up in a foursome with the customer on the floor in front of the porn movies on the wall (like the old DVD movie stores). Any idea where I can find it?
