Found this gif on Twitter , it looks like from an AV film. From this short gif, I think the girl has seen something sensitive at her friend's house. I think it's kind of interesting because I've watched some movies with this kind of plot but usually it's a woman finding something that belongs to a guy. If you can't id the movie, even id'ing the girl is enough I guess. This is the link where the gif appear. https://twitter.com/9GAGTweets/status/730282230287831041Thank you
