HAVING SEX

Sex is an ability check, using your primary class ability + your proficiency score.

The base DC of a sex check is your 8 + Primary Class Ability + your proficiency score. More experienced targets are harder to satisfy.

Sex Points

When you roll for sex, you gain a number of sex points equal to the difference between the DC and your roll. If the difference is 0, you gain 1 sex point. It is possible to have negative sex points

You gain sex points for the following

• When you deal damage to an enemy
• For any damage you've healed. 
• If you cast a spell that doesn't deal or heal any damage, you gain sex points equal to your proficiency bonus + spell level * 2 
• When you take damage from an enemy. You don't get sex points from damage taken from an ally.

You still gain sex points from Climax actions or Kink Talents as well.

Additional Size Fetish Rules

All the actions under these rules are taken/granted for free. They are as intrinsic to PCs as the ability to gain experience or unarmed attacks.

Grappling

Grappling against creatures of a smaller size category:

You can use your action to try to pin a creature grappled by you. To do so, make another grapple check. If you succeed the creature is restrained until the effect ends.

When you have grappled a smaller sized creature and that creature is within your encumbrance you can move normally. You can move that creature anywhere within your reach.

Designer Notes

Sex Toys no longer exist, all damage contributes to sex points.

The spell Enlarge/Reduce and the Rune Knight class no longer exist, growth is managed via other means.

Tiny Ingenuity

Tiny characters have creative ways of getting around. Their small size easily enables to create vehicles at low cost and effort.

A character can create a Tiny vehicle during a short or long rest, especially through magical means. However, these vehicles are usable by only characters Tiny or smaller.

Tiny characters have proficiency in driving any vehicles made for them.

All tiny vehicles have 5 HP.

Flying Machine

A leaf as a hang glider, a piece of paper as a plane. You might ride in a mage hand. These may or may not have magical propulsion, depending on your class.

This machine is your size and gives you a flying speed of 30 feet.

Land Vehicle

A toy car, an animated table, etc

A tiny land vehicle has a move speed of 40 feet.

Boat

Sailing speed of 40 feet

Submersible

Underwater speed of 30 feet, breathing capacity of 1 hours (for a tiny)

KINK TALENTS

Kink talents are an ADDITIONAL system where players can choose options to fulfill specific fetishes.

They are IN ADDITION to Feats, ASI, Classes, and Sub Classes. 

Kink Talents enhance your character in some way over a long period of time. All Kink Talents have an upkeep cost. Add the upkeep cost of ALL your kink talents to the cost of your Climax.

You cannot take multiple copies of the same talent.

CLIMAXES

A character can have one climax at a time. You can change climaxes between sessions.

Activating a climax is a free action. You can only activate one climax per round.

Climax Power

Climax Power enhances your climaxes. Kink Talents can enhance Climax power, while Climaxes use them to increase damage, DC and/or healing

Designer Notes

By limiting the amount of Kink Talents and Climaxes, we embrace a D&D trait: Planning.

In this system kinky sex acts are no longer improvisational, they are the result of careful planning and pay off. This is how D&D generally works with classes and feats. If players plan ahead of time, now they only have themselves to blame if they have difficulty tracking modifiers.
