Seeking Games where you have to corrupt one person.

[AsTr]

Looking for a game where you have to corrupt a person like teaching feeling or the elven conquest games.

 

[Pretentious Goblin]

Here are trainers that have a heavy emphasis on corruption of a single character (that's not the MC).

Princess Tower
Orange Trainer
Cummy Bender (some content with a secondary character may be unavoidable)
iNSight of you (some scenes with secondary characters are unavoidable, but I think the "slut" path for them heavily reduces the unavoidable sex with those characters)
Mistress vs. Slave
Corrupting the Priestess
Soldier's Life
News Desk (I think the daughter content is avoidable for the most part)
Ruin Me
Bitch Breaker
