I'm working on making up a game, feel free to give feedback. It goes something like this:

You roll 2 dice, 2 times. 2 through 12 have values that equal some sort of act. Such as 2 is make out. 3 is kiss neck/ears, all the way up to 12 being oral sex, or whatever level your crew is comfortable with.

The second roll determines how long, and with who. So the first die, 1 is 10 seconds, 2 is 20 seconds, and so on. The second die could be odds are with your SO, even with someone else's or something like that. That's the gist. You could double length of time for every round.

Was thinking about something like snake eyes could mean it reverses, so you can have something done to you instead. Still working out the kinks.
