a salaryman entered a restaurant and ordered a high-priced menu "sister meringue" that a regular customer seemed to have ordered. when he opened the door to the back room at the urging of the landlady, there were two young sisters! a naked girl is presented in front of the bewildered man! "i'll take this! big sister! little sister! amazing freshness!" after savoring the small bodies, the ultimate "secret menu" is a 5-star mishéran oyakodon that even the landlady can enjoy! gourmet and erotic hard-boiled!
