Prob one of the games that shows almost all the forms of Netorare is "Scars of Summer"Netori means you are the one stealing someone elses loved one
Netorare means you are the one being stolen from; you aren't happy about it and/or don't know about it.
Netorase means you are the one being cheated on; but it's consensual and you know about it.

Netorare is differentiated by how it happens / the feelings of the heroine:
Type A - Consensual from the start; she's down with it
Type B - She doesn't like it to begin with, but starts to like it and turns
Type C - It's non-con from start to finish - AKA rape
if i remember the name correctly. only one that not covered is rape i think in that one
