This one is a nice thread. I wasn't aware of this one until a couple of minutes ago.
I'm a big fan of netorare. I kind of enjoy netori, although I'm not really a fan. I absolutely despise netorase.
My favorite netorare VN ever is

. This one is definetely a masterpiece and made me a fan of netorare. It represents all that I think that should appear in all NTR works: build the relationship between the MC and his girl, show how they met, fell in love and got together; only after that show how the girl ends up in another dude's hands, slowly build up the relationship between the girl and the other dude until she finally falls and the MC loses her. It creates a vibe of mystery, drama and jealosy.
Sadly, most of the so called NTR games out here don't have anything related to netorare. Babysitter is an example here (the MC doesn't have a close relationship to the girls). So is Anna Exciting Affection (this is pure cheating and corruption).
Basically, only Japanese works do it right. Not a surprise since most people on the Western community just don't understand the difference between netorare and cheating. Not really their fault, since the closest word to netorare in an English dictionary is "cuckold". But I digress. I took part in lots of debates around the internet trying to explain it, but people just don't get it.
The only western game that I think almost did the NTR right was My Girlfriend's Amnesia. Unfortunately, the dev just doesn't know how to write sex scenes and only focus on the animations. He seems to have improved on his last game. I'm keeping an eye out for it.
Hana's Boat Trip actually had a decent NTR ending.
Living with Temptation 2 also has an ending that I considered pretty decent in terms of netorare.
