SW-1037 Couples swap and swinging! On a hot spring trip, a wife with cuckold fantasies wants to be with a man other than her husband!

Three married couples have come on a hot spring trip organized by the neighborhood association. A reserved middle-aged couple is invited by their neighbors, a more openly flirtatious married couple, and ends up getting swept up in the moment in front of the husband. The excitement of watching and being watched heightens the experience, making the pleasure even more intense. In the bath, in the hallway, and under the futon, the wives become captivated by men other than their husbands.
