A female college student falls into a creampie soapland

Minami is an honest, cheerful, and serious female college student... She visits a frightened sex shop and is given an astonishing practical instruction interview that same day...but she still doesn't know about it. The selling point of this shop is that raw creampies are OK without condoms...Even though she escapes from fear, she runs into her home, and the customers force her to serve her creampies and tears flow.
