It's good, but a bit short, and it ends up leaving you with a "wanting more" feeling, which I think is intentional, since at the end it's clear that there will be a sequel.
However, the "wanting more" feeling is valid even for the fetishes.
Even choosing the "hardcore" option, I was kind of expecting a longer scene with more things going on.
The girls say they love the MC, but I don't remember seeing any really romantic scenes or anything building the relationship.
A lot of things seem to have happened before the beginning of the game.
I can't imagine someone "loving you" just because they had sex with you.
But the game is good for the short time it lasts, and the visuals are good.
I would give the facial expressions a 6/10, however, and the dialogues during sex I would give a 5/10, not very immersive or I didn't feel the mood from the dialogue.
Personally, I would have built more of a relationship with each LIS, so that I would care more about them.
