It is a genre of anime (most commonly found in hentai), with a specific idea at its centre - cheating. It has a (main) story where the protagonist has his/her lover stolen by someone. The sex in an Netorare hentai/NTR hentai will focus more on the couple that is having an affair together, rather than the married or dating couple whose relationship is being violated. Netorare/NTR usually has a female character as the one who is cheating on her husband or boyfriend, but it can also be a male character as well sleeping with other girls. Quite often, Netorare hentai/NTR hentai end in depressed, regretful, and rage-filled characters rather than happy endings.
