Pretty demanding specific are we? Well I can also think ofAre there any that employ the same mechanics as in the route ( mc being oblivious to whats happening r8 in front of him and doing nothing to stop it )?
I've already played most of them btw
Wife stealing inn
Loretta brand new job
Divine Iron Awakening
Girlfriend tapes (sorta)
Yuri and Claire (sorta)
If you want more
I might just make it quick and quote other recommendations i made before to other people
Games from Atelier Sakura - almost all of them some way or another fit
Games from NTRMan - Adelaide Inn fits the most
Games from Soraue - the dangerous changes and the 5 days of separation series fits
Games from Hangover Cat - not really but close enough
Games from shirachiku castella - same as Hangover
The recent Minako countryside wife
The old classics Inn my wife , Knightess Whore, Ntr bar phyllis , Karma Rain , Warped Desires Shelly
