The MC was male and the objective of the game was to mind break a girl, which had a skin tight purple lates suit. There was also another girl which had already been turned into a slave. The main kink was breast expansion, with the captured girl being teased and having her bresasts enlarged. I think there was also a mechanic where you could drug the girl to make the mind break easier. After each session, I think you were shown some stats about the girl (like breast size) which increased depending on what you did, but I'm not really sure about that last part. The game might have been japanese too, but was translated.
