When I moved down to London from the north aged thirty I soon got in with a promiscuous crowd, largely through visits to strip pubs and the old Craigs list. It comprised all sorts, bored housewives, randy divorcees or widow(er)s, assorted nymphos, straights and gays, as well as horny single guys like me looking for what London's sex scene had to offer.
One guy had a version of strip poker that as far as I know was unique, which we'd sometimes play at raunchy parties. We would try to get together equal numbers of men and women, ideally two or three of each. Each player was dealt a hand of a few cards, and the rest of the deck was left face down on the table. The cards themselves were worth a comment. On the back was a picture of a well stacked naked woman squatting wide legged in front of a naked man standing with his hard up dick in her mouth. You can imagine how the king, queen and knave were depicted!
The rules were simple. Each player took a card from the deck, and either added it to their hand or put that card or another from their hand face down next to the deck. The aim was to accumulate a set, which might be consecutive numbers in a suit, a set of ace, king, queen, knave etc. When a player got a set, he or she called "show", and all the other players had to show their hands. All the players' number cards were added up, and the player who'd called "show" took a garment off the player with the lowest total. Simple! The speed of the game could be controlled by specifying the number or type of cards making up a set, or by the number of garments a player was wearing!
As soon as a player was nude they dropped out of the game, which speeded things up. Also when they got nude they took a "forfeit" card, like chance in Monopoly. There were blue forfeit cards for guys and pink for girls. Forfeits were things like showing your masturbation technique, doing a kinky nude pose, confessing early sex experiences and the like. The last person with any clothes left on was the winner.
Though we were sometimes drunk when we played and my memory has faded I recall a couple of memorable games.
