This piece arose from a different story. I needed a device to get the boyfriend of the main character to sleep with her own mother.
One of the ways was for the main character to play adult party games to get her boyfriend used to being naked. I rejected games involving skill (like Strip Table Tennis). Imagining men and women naked playing table tennis was erotic. But I rejected this because the younger and fitter boyfriend would win.
This led me to consider games of chance like Strip Poker and Strip Roulette. I rejected roulette because I wanted the game to be rigged against the boyfriend.
So I settled on Strip Poker.
But there is a huge difference from being naked and agreeing to participate in sexual acts. Hence the desire to incorporate sexual activity into the Strip Poker routine. I needed a game that required less skill and was quicker. That led me to invent the Strip Auto-Sex game. It is based on blackjack. I unskilled blackjack so each player has no choice when to draw a card or to stick.
This speeds the game while still getting the excitement of seeing other people get naked. But crucially it also incorporates consensual sexual acts.
CONSENSUAL SEXUAL ACTIONS
Getting a device that guarantees consensual sex in a game with 10 or more players sounded easy. I found it quite difficult.
My first thought was for the characters to simply write down their sexual preferences. But I quickly saw the difficulties. See for yourself how difficult it is to list all sexual acts. That difficulty was partially overcome by using Wikipedia's list of sexual terms.
I started with the idea of 4 such lists (male dominant to female, female dominant to male, same sex dominant to same sex and same sex submissive to same sex). But that would involve lots of time and paper. So I changed this into one piece of paper. It would have a 5 column arrangement with the following sex acts.
HOW TO PLAY AUTO-SEX
Take a piece of paper headed "Sexual Appetite". This shows lots of sexual practices, which you can indicate whether you wish to practice (or decline to practice).
You may have to do these acts in front of other people.
You may want to be wanked by a woman but not by a guy. You may want to fuck a guy but not let him fuck you.
Record any actions you LIKE by a tick.
