It's Not a Date (2014) on Netflix

Plot summary

Carly Sagat and Milo, both in their twenties, meet at a local club for what Carly calls a casual meeting rather than a date. Their conversation escalates into a night of passion, and the evening does not follow the usual pattern of a first date toward a romance or a friendly parting. Carly has had enough of a dating life filled with disappointments, and she considers Milo the worst of the men she has gone out with. Instead of letting the night end, she takes him on a detour of her own devising, one that grows extreme enough to make him regret ever agreeing to meet.
