Finally an Isekai where they do it and people complain. There is like a million other isekai with no action, which I'm reading as well - it's not like all are focused on ecchi. It's just this one.

I mean stuff like "When she's thrust into, she can't help making a dumb face, the girls of this world are really pitiful."
What the hell is this dude's problem?
