In a school where there are many neat and clean girls, the gyaru girl who gets the most attention = Lumina Sena.She had high grades when she entered school, 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, decides 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 viewers are subjective from Oniguchi's point of view, making Rumina Sena, who is a little cheeky but cute, obscene and mellow, and enjoying her serving her, like the taste of aristocrats.Even though she has the appearance of a gal, "Oh, my God... Oniguchi, you're too good at it...!!" "What's this...?Conveniently, it seems that the whole body becomes sensitive due to the effect of lewdness, and eromanga says, "Oh, oh! Show me just like Iki!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!
