SDMUA-068 What would happen if a man and woman with strong sex drives, who are in adult videos even though they have boyfriends or girlfriends, spend 18 hours together? 【Sex Observation Documentary】

In January 2023, half a year has passed since the enforcement of the new AV law. In times like this, I want to see erotic scenes without a plot. The director invited 6 men and women with strong libido who are appearing in AV even though they have boyfriends and girlfriends to a secluded cottage. There is one pre-determined contract, "Girls can have sex (insertion) up to 2 times, and anything else." What will happen during their 1 night, 2 days and 18 hours?
