'Azumi,' who teaches calligraphy to children, one day has her heart stolen by the erect penis of her student Kenta. Azumi can't stop thinking about Kenta's little dick. She gives him a blowjob and teaches him titty-fucking in the bath. Eventually, she ends up having raw sex and raw internal ejaculation with him. On her ovulation day, she lets all four of her students have raw sex with her and makes them cum inside her ten times in a row.
