The friendly Imai couple and Hoshi couple found a cheap inn and went on a short trip. However, the owner of the inn had run away in the middle of the night, and it had become a den for squatters trying to prevent an auction... Unaware of this, the couples visited. The men set their eyes on the two beautiful wives and, unbelievably, engaged in intense sexual acts right in front of their husbands. Furthermore, they forced the couples to switch partners and perform forced internal swapping. Eventually, it turned into a chaotic orgy filled with a mix of bodily fluids and screams...！！
