In a school where there are many neat and clean girls, the gal girl who gets the most attention is Sena Lumina.When she entered school, her grades were high, but after she entered school, her grades gradually dropped, and now she seems to have become a complete idiot.She's by no means a bad girl, but her flashy looks make her teachers look down on her.Oniguchi, a chemistry teacher, decided to use the lewd technique "Chorokunaru", a supernatural power that only one human being possesses, in order to save this lovely gal (or at first, he had no intention of saving her at all).Let me explain!What is Choro Kuna? By showing the evil eye on Oniguchi's left hand, the girl in front of her loses her rationality, and by increasing her own sexual curiosity, her estrogen secretion changes. If it's a cod roe, it's the nature of the genes...unununkannun, so in the end any girl will end up being shabby, so ah!That's amazing.Waganne for details.So, it is the reason to save Rumina Sena by SEX with her lewd technique. I don't really understand how sex can help me because it's outside the chemistry curriculum.This work is a luxurious work that the viewer is subjective from Oniguchi's point of view and is a luxurious work like aristocrat's taste who enjoys the sight of her serving her.Even though she looks like a gal, "Oh, my God... Oniguchi is too good...!!" "What's this...?Conveniently, the effect of the aphrodisiac seems to make the whole body more sensitive, and it's like an erotic manga saying, "Oh, oh, oh, oh, that's no good! Show me a lot of live!After appreciating Lumina's masturbation dressed in a super-suitable succubus costume, she cums many times with a hard piston and puts it inside her vagina as requested. Doppyun!Yabe.pretty!Iki face is cute!You should really watch it.The strongest gyaru moe work is born!
