Dunno bout others but to me, real ntr is about drama and it's main goal is to make the readers/playas feel sympathy to the mc and get aroused at the same time at the cheater. It usually delivers well if the mc is a man imo.
Would be best if it's unexpected so I would suggest forget the cheater's pov. Just give the audience a wee bit of hint and they will crave the thrill of the hunt for catching them red handed.
Of course, there's this cuckoldry but... I'm not against it... But I usually find their plot cringy. How the mc finds pleasure in humiliation, I'll never know (shrug)
Or perhaps, the mc has a narcist dad/boss/teach/don, coerced mc to let his <....> have his way with his wife/gf and uh well... That could work i guess.
