These innocent girls have not yet been taught about sex by a man. An old man will teach them how to have really good sex. Erogenous zone development > Maki-chan. Deep throat > Mai-chan. Training to be a submissive female dog > Non-chan. A dick as a reward > Hikari-chan. Clitoris orgasm training > Ai-chan, etc... The girls were scared at first, but now they're crying and drooling as they give a blowjob, leaning their bodies back as they reach orgasm... This is what happens when you teach a girl about sex on her way home from school...
