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

When you deal damage to an enemy, you gain sex points equal to the damage you've dealt or hit points you've healed. This includes climax actions like smother, vore, etc.

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.

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.
