I'm looking to do an actual RPG game with a player here with sexual elements. This was inspired by another post here who wanted to do an actual RPG but without combat, just exploration. This got me thinking.....

I'd like to create an actual game mechanic that can be used with StarFinder or any other system - a bolt on expansion.

For the story it would be quite basic - A young single explorer crashes onto a unexplored planet and because of her alien pheromones everything on the planet is aroused by her. But the story is the mechanism to test and evolve the rules and is not the main event.

Intimacy Encounter.

Intimacy Encounters are the sexual equivalent of combat - they are resolved over rounds where various actions occur. How long each round lasts in physical time is irrelevant. The encounter lasts until at least one character reaches their Pleasure Threshold

Pleasure Threshold and Arousal Points

Each character has a Pleasure Threshold (PT). This starts at 10. During Intimacy Rounds acts the character accrued Arousal Points until they reach the PT, at which point they orgasm and the Intimacy Encounter is complete. At level 2 your Pleasure Threshold goes to 20, but you can still orgasm at 10. (We need to work out the orgasm rules for edging and other kinks like denial and forced orgasms). At each level your orgasm pleasure level is determined by rolling your upper Sexual Intimacy Dice (see below)

Sexual Experience Level

Each character has a Sexual Experience Level (SEL or SXL). All characters start at 1, which is when the characters only experience is self pleasure . A character can only progress a level in an intimacy encounter with at least one other character.

Sexual Intimacy Dice (SID)

The SID is basically how good a character is and grows with the SXL. At level 1 your SID D2 - you’re inexperienced and it shows. At level 2 it grows to D4, then D6 at level, etc. At level 7 it would be D20 and stays there until it doubles to 2D20 at level 14.

Sexual Actions

Each round a character performs one sexual action. The choose what action to take from their Kink abilties and rolls any dice up to their SID limit. That roles give the Arousal Points to the target character or characters.

Kinks

Each player starts with 2 Kinks from a list of kinks, plus the Touching kink. Touching could be hold, stroking or kissing other characters. So at level 1 you can do D2 Touching arousal. Some kinks can be Giving or Receiving (GR) - you can pick each kink once for Giving and once for Receiving. A kink may require another kink before you can have it . A required kink must match the GR of the kink you’re taking - you can take Breast Torture R when you have Breast Torture G

Kink: Touching

Kink: Oral (GR)

Kink: Vanilla Sex

Kink: Spanking

Kink: Breast Play (GR)

Kink: Breast Torture (GR) requires - Breast Play

Feel free to DM me about helping develop this - I feel very excited and think this could be a really good system to develop. I'd like a female to help with this because if a bunch of men do it themselves the female side of sexuality would be missing something. This will need playtesting and evolving, which is what the adventure itself is for.
