Yeah I love unique ntr progression. So many games go the similar route of groping - hj - bj- thighjob - sex - anal - group. With perhaps slight differences, it becomes predictable and somewhat boring.
The game giving you red herrings about corruptors etc... its really great. Same goes for ntrpg 2.
Personaly I am liking more and more when the ntr hits out of nowhere and it goes straight to the thing, where heroine body is completely taken immediately (by that I mean immediately after corruption starts, not immediately in the story itself), but then its about corrupting the heroines mind and heart.
I really enjoyed Leane 2, because the game builds up the Holy King title, and how you swear absolute loyalty to the king. You're fighting for the country, and you averted a crisis by having a spare guy take up the Holy King role, and you know the king needs heirs to safeguard the kingdom.
It's this twisted feeling of knowing that what the NTR guy is doing is completely justified, and you're somewhat powerless to stop what is going on without being labeled a traitor to your country. The girls at the start don't like it, but they know they have a duty to make children.
It's so hot.
I was without internet for 2 weeks, and I played that game for the first time, going in completely blind. God it was glorious, I could feel my body get heavy and my heart start pounding the second the twist happened.
