寝取る is the active verb meaning 'to steal someone's partner', while 寝取られ is the nominalized passive form referring to the act or genre of being cuckolded.
Derived from the passive form of 寝取る (netoru), a compound of 寝る (neru, 'to sleep') and 取る (toru, 'to take'), literally 'to take while sleeping'. The nominalized form 寝取られ (netorare) came to denote the genre of cuckolding in erotic contexts.
