Yeah, this is hot.
Like, the fact that they don't lie to themselves about their feelings and desires is fun.
And that they actually have a real reason to NOT commit to it is good too.
Just don't NTR this story. Lately, mangakas have a tendency to switch the tone of the manga near the end, to fuck with their audiences I think. Please just don't.
I want to be sure that they fuck when they both get to be 18 and fulfil their promise to the witch.
And then, I want the story to continue a bit, where they are together, often having sex, but still unaware of the fact that they see each other masturbate by magic...
Like him trying to put reigns on his libido in front of her to not pass for a creepy pervert, then jacking off alone.
Her trying to stop herself from bouncing on that D 24/7 to not seem too slutty, then flicking her bean non-stop in her room.
Well, that's my hope. They'll probably fuck it up somehow, lose the bet and then she gets raped by 10 black dudes while loving it in front of him while he's getting butt-fucked by a trap or something.
