@AfterMidnightMoon ain't no girl in this whole damn manga has gone for a round less than a third of a day. They work a dick like they work a job, 9 to 5
If you reverse the premise of this manga, you get teenage boys, who cum in their pants as soon as a girl touches them. Well, not that far from our reality at all.
Honestly, I would've liked it more if she actually resisted, it would pose as another problem for MC and we'll be presented other ways of circumnavigating it, instead of his ultra horndog powers. But then again, this manga exists for pleasure.
@fortnog, your idea is good, but not at this particular occasion, because this is actually the very first time Youta tries to use his "horndog" power to avoid danger/solve problem. If she actually resisted, it would really undermine his role and value as the only man and gives an implication that the other girls who falls to his charm are too easy.
Maybe when he's against the last boss or something.
