N.T.R is a genre of romance (Japanese) that is common in Hentai. The abbreviation refers to the term "netorare" or its translation of willing unfaithfulness, but not always. Netorare is an consented act most of the time of romantically complicit sexual infidelity to varying degrees. As a fetish, NTR is the situation in which a person gets turned on in observing sexual situations of flirting, kissing, fondling, and more. It is commonly compared to the word "cuckold" and "cuckquean".
