Some thoughts on the game after having played it:
Weird start, the two main themes appear to be free use and NTR. I wouldn't call it classic NTR since the MC didn't really seem too bothered by it, but definitely some form of it since your love interest has sex with someone else in front of you. Not enough content to know if you'll see anyone else or if it's purely your love interest who you see having sex.
I'm not sure if this is more of a prologue or proof of concept, because as a prologue the whole her having instantly having sex with her boss right then and there in front of you is incredibly rushed and weird, but if it's more of a proof of concept than that's fine. If this is a prologue I'd honestly say it's not very good, but as a proof of concept it's about as good as one could be, even if I don't particularly like the fetishes involved. The art's fine, the games short to the point that's not really saying much, but if it keeps it up then it'd be pretty good.
It's really hard to rate something this short, especially without knowing how similar this will actually be to the real game. Not my type of game from what was shown, but it could have potential if you're into free use or NTR, just way too little content to really know.
