I'm currently running a one-on-one game that involves a Dungeon-like setting wherein female contestants must face off against various monsters and one another. You can read about it here
We're using The Window to provide an element of randomness, and so far it has been great. But now the character is facing another contestant. She is in an arena. Both girls are nude. Here and there on the floor are "pleasure nodes." Step on them, or fall on them, and they increase arousal.
The first contestant to force the other to five orgasms wins.
The arena has certain properties that encourage this, besides the nodes. First, the arousal of the contestants is being magically sustained in that, once they are brought to a certain state of arousal, they will stay that there, until they orgasm. They can't just dance away from their opponent and get less horny. The only way to reset the scale is to orgasm.
Second, the arousal of the contestants is affected by the crowd. This is meant to encourage the Contestants to tease and taunt their opponent. The more the crowds scream their name, the higher the arousal of their opponent will go.
What I'd like to do is use The Window to describe the escalating action using die rolls. The player describes an action and makes a roll. I respond with a roll for the NPC. Whoever wins gets to force the other character to make a Chastity roll. The TN for this is either 6 or 4, depending on the area of the body they can access, if the other character is on a node, or if they have discovered the other character's weakness.
Failure raises Arousal. Success keeps it from rising. After the third failure, the Contestant climaxes. Her Arousal scale resets to zero, and the contest continues.
The issue I see with this is that it is a lot of rolls. Is there a simpler way to resolve this while still keeping the element of uncertainty? If you have any ideas, please share!
