Outdoor. Midnight. Swing house.
Play
Couples. Keys in the bowl. They fuck someone else's partner.
Play
They drink first. After midnight the partners are mixed.
Play
Couples in one house. The orgy is the point.
Play
Bi couples. They swap. Then it is an orgy.
Play
The food is done. The couples are not.
Play
They were swimming. Then they were fucking.
Play
The women do not wait for the men.
Outdoor couples already swapped. Pool, then the orgy. Swing house tonight. Bi couples who trade and then pile in. Black couples at a BBQ. Asian pool that stops being a swim. Girls at the party who do not wait.
