Seems to be the case if you achieve ending one then it pretty much removes the NTR element, in fact i am actually having difficulties to get the NTR route going now that i have the "Safe" ending of sorts.
There really isn't much to this game. Playtime 1-2 hours.
There are 2 scenes each for the side caracters.
A couple more for the wife. Feels rushed and abadoned.
Molest your wife in train 3 times. At home when you are at your desk to decide which path you wanna play, pick the bottom choice. (yes the translation is so fucked up here and both have the same text -.-)
I have not gotten that option, do it 3 times and then the computer doesnt give any options. It's aways end 1. Am I doing something wrong? Mind sharing a save with the NTR route will begin?
