In a school where there are many neat and clean girls, the gal girl who gets the most attention is Sena Lumina. When he entered school, his grades were high, but after entering school, his grades gradually declined, and now he seems to have become a completely stupid character. He's by no means a bad boy, but his flashy appearance has earned him the cold eye of his teachers. 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. That's why I'm going to save Rumina Sena by SEX with her. I don't really understand how sex can help me because it's outside the chemistry curriculum. This work is a luxurious work like the taste of the aristocrat who enjoys the appearance of the viewer who is a bit impertinent but cute Sena Rumina with aphrodisiac and enjoys the appearance of serving from the viewer's point of view. 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!
