These are just... really bad. The series.
You claim to offer choice in the game, but in reality you can do 2 things:
1: Play the game as a cumdump with no needs or self-regard, that lives to pleasure dick.
2: Be a celibate, prude nun and skip like, 90 % of the game.
That's like, the opposite of choice. That's railroading.
It doesn't help that all girls are just copy pasted, genital wise.
That's just lazy.
UMCH wouldn't be as shoddy, if you were just upright with what it actually was.
Like, just don't lie about what you can do in it, or what it is.
It's a perfectly decent cock worship simulator without depth. Tbh: You may as well borderline just play as some dude. But, I guess this way you get to add more dick designs.
