Adult hide and seek
Here is an idea for an adult version of hide and seek. It is geared for people that are into, or want to try swinging. For this game you need an equal number of men and women. Each of these need to be a part of a male/female couple. The couples need to have an actual relationship. No going out and hiring a prostitute. And you need a large area to hide. Possibly a large privately owned forrest.
The couples gather in a central area. Possibly a cabin in the woods. This will be the base. Each of the ladies are dressed in one less article of clothing than there are men. (This is written with the women being the hiders but you could switch it around and have the men hide.) The women are sent out to hide. They are given 30 minutes head start before the men come to find them. The women can move around while the game is in process. The men come out and hunt for the hiding women. When they find one they remove 1 article of clothing from the lady. Only 1 article per man. If a man finds the same lady more than once he cannot strip her again. Each man keeps hunting until he finds a lady that is naked. This lady may not be the one he came to the party with (presumably his wife or GF). When he finds a naked lady he takes her back to base. When all the people have come back to base starting with the 1st man in and continuing with each man in the order they came in each man brings the woman he found into the center of the group and fucks her while everyone watches.
