Last Tango[2011]

Loosely based on Last Tango in Paris, this flick is about a woman who rents out a secret apartment to escape her fiancé, and ends up having an affair. The movie won The Feminist Porn Awards' 2012 prize for "Most Arousing Adaptation," and was lauded for its "haunting, explicit sex scenes" and "emotionally rich performances." A must-watch for people who like a lot of romance and plot with their porn.
