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!
