That sucks. And is also weird.... I'm pretty sure I've seen explicit stuff there before...
I actually own games where a girl is raped by ogres and goblins on Steam.
Your game is mild in comparison. AND it has a story.
But maybe this is one of those 'people don't mind watching girls get tricked into sex and misery, but they hate to see a girl willingly being sexual and happy about it' shit again.
(I read Bjørnebo, one of the intro's to his book mentioned this is a typical idiot view people have.
I kinda thought humanity got over that since it's the 2000s, but maybe I was wrong.)
