Kanna and Yuna are close friends since childhood, close friends until they get married. Two friends invited the husbands and husbands friends to go on a trip to a beach.
While returning to the hotel, everyone was laughing and joking with each other, they drank a few glasses of wine. By the time the alcohol was intoxicated, the two husbands had the intention of having sex in the living room.
At first it was just a soft swing, everyone's wife had a cup, but it was hot with alcohol. The two husbands changed their minds to change their wives to make love, and at the same time invited some of Fa's best friends to join.
The collective sex party to change husband and wife is extremely lewd, passionate and invites fellow prostitutes to watch.
