Recently, "cosmetic surgery of the lower body" has been secretly booming among men. People who go to the hospital are short and small, and people who want to make it bigger even though it is the average size are going to the "Penis Enlargement Clinic". At this clinic, all the staff, including the director, are only beautiful doctors, and it is famous that reservations cannot be made.

A big hit! The fourth installment of the sex-infused daily life series! This time, schoolgirls have sex on a school trip. Even when they are being vigorously pistoned by a raw dick, they ignore the penis! On the bus, while the landlady is greeting them in the garden of the inn, while the head priest is sermoning, the school trip progresses while they are "constantly having sex" in situations where they absolutely cannot make a sound. For the first time in the series, they have sex while completely naked in the bath!
