So I´ve tried
My Perfect Sister.
I must say, it´s a pretty good start to a game.
If you haven't tried it out you should, it left me with wanting more^^
Yea this game is good and has potential.
Also, even though it is technically NTR according to the definition of this site, Its really not my kind of NTR or the type people are used to in this site.
Its closest to Netorare type A as defined by VNDB: " The heroine is willingly cheating on the protagonist with another guy and enjoys every second of it. No rape, blackmail, drugs etc. involved, it's consensual sex from the very beginning."
Again, I dont know if this type of netorare is fully applicable either cause the sister doesnt really cheat on the MC. She just likes someone else from the start.
Its kinda like this-
Hey I like this girl and shes single.
After a few months...Oh no she has a boy friend now ... THATS NTR!!!!
Thats kinda what happens in the game.
I do not want to go into the argument of whats NTR and whats not.
I simply like a different type where there is some level of reluctance from the female character.
Having said all that, game is still pretty good and worth a try. Even though its 0.3, there is a good amount of content.
