A one night stand or a simple on and off thing. A will they, won't they heartburn full of wild emotions. A friend's with benefits type situation, strangers in a toilet or colleagues at work. From roommates to lovers to a hot fling with an ex. A notification that makes your heart race or just a touch of skin without any feelings.
