I'm looking for a fanfiction where Harry randomly decides to become a porn star because he saw an advert. He has muggle electronics in a warded room. He refuses to marry Ginny and she gives him an ultimatum so he leaves her. The group of friends hold regular parties/movie nights. Someone brings a dvd of Harry porn and Hermione recognizes his scars. Ends with Harry/ Draco.
There is almost no actual porn in this story. It's mostly just background info.
