This is a marginal village where the majority of the population is elderly people living alone, and nurses provide home visits and support to the residents. This time, it is a documentary that closely follows three married visiting nurses. "No matter what happens during work, I will calmly respond and provide medical care so as not to make the patients anxious," they say, exposing their plump asses while examining the patients, and remaining calm even when they are suddenly fucked. They perform their duties while being fucked hard and squirting... but when there are no patients...! How long can visiting nurses endure the ultimate orgasm endurance?
