Current Rules (HEAVY REWORK IN PROGRESS)

There are a good number of new rules added to this version. Some rules are subject to change to be more balanced for the sake of more exciting combat/storytelling.

DND: Sexual Combat Rules.

Pregnancy Chance: Female creatures can, of course, become pregnant. To determine if they do or do not, a d100 is rolled. If above a 50, they are pregnant. If 50 or below, they are not. This can increase based on the creature or lower. Negative bonuses to the roll make it harder to impregnate (if -10 to PC, the roll must be higher than 60), Whereas a positive makes it easier (+10 means above 40).

Lust: Female creatures (That can be fucked) Now have their HP replaced with LP. LP is Lust points. All damage becomes Lust instead when dealt to a Female creature. This does not make 100% sense, but it is the easy and balanced way to change how the combat works for this story. Instead of hitting them, it can be flavored as you Groping them or something of the sort. Maybe attacks that can't be flavored this way (Fireball, for example) will, instead, destroy clothing. When a creature's LP reaches 0 (Can no longer resist the urge to fuck), they will exit combat, likely just falling to the ground, masturbating to try and scratch their itch. After combat is over, they can be fucked. Note: Not all females have to follow this rule, they can follow the normal combat rules in unique scenarios (Such as if an animal, or monster attacks, and does not want to fuck, they can attack females like normal instead).

Before this version of the rules, there was a lot more to it. But it became too complex at some point, and I decided to make it simpler, partly so I could actually write my story and later make a version of this that all can use for their own stories. I will try to add some unique parts as well.

Things that can change the Pregnancy Chance

Features:

Fertile: Girls between 18 and 25 have this stat. Adds +20 to their PC.

Mature: Girls between 35 and 45 gain this. Adds -20 to their PC.

Extra Fertile: Some girls are simply extra fertile. Adds +10 to their PC. Aside from if the girl cannot bear children, this feature can be given to any girl seen fit.

Less Fertile: Some girls are simply less fertile. Adds -10 to their PC. Can be given to any girl seen fit.

Barren: With the exception of magic, they cannot bear children.

Potent: Any guy can have this, but not all do. Adds +10 to PC when they cum inside a girl.

Impotent: Any guy can have this. Adds -10 to PC when they cum inside a girl.

Sterile: The guy cannot get girls pregnant, regardless of the reason. Magic may be able to help, however.

Potions and Magic:

Fertility Potion: Gives a girl Extra Fertile for 3 days. Counteracted by Barren Potions.

Barren Potion: Gives a girl Less Fertile for 3 days. Counteracted by Fertility Potions.

Potency Potion: Gives a guy Potent for 3 days.

Sterility Potion: Gives a guy Impotent for 3 days.

Baby-Making (Level 1 spell): If used on a female creature, makes them have Extra Fertile for 3 hours. If used on a male creature, gives them Potent for 3 hours.

No-Babies (Level 1 spell): Girls gain Less Fertile for 3 hours, Guys gain Impotent for 3 hours.

Anti-Sterility (Level 1 spell): When cast on a guy that is Sterile, it can give them a chance to get a girl pregnant, but they must get higher than 90 (Not including other modifiers, like potions or other spells.) It only gives them ONE chance before this must be recast. When chance is used, it does not remove the effects of potions or spells, it just makes them useless unless this spell is cast again. This spell does the same for girls with Barren.

Homebrew and Other Changes

Backgrounds:
Breeder; this background is for those with experience in breeding and fucking girls. They gain proficiency with Sex toys. They also start with a magical item called the Breeder's Ring. They gain proficiency in Persuasion and either Performance or Athletics.

Magic Items:
Breeder's Ring; When a woman is fucked and impregnated, they gain +1 Breeding point. At 5 breeding points, they can be expended to guarantee the next five pregnancies, even in barren wombs.

Tools:
Sex Toys: Has no real stat bonus, primarily here as something that makes sense to add, can flavor what they are to make some things more interesting, though.

Potions:
Wizard Healing Potion: It works like a normal healing potion, but it can be used four times before it goes empty. Heals 2d4+2 hit points.

Companions: This rule is unique for some NPCs you can make. The companion is an NPC that can follow the party, doing various tasks and helping out. The companion has two more health than the creature's average health (EX: Goblins have 7 health, so a goblin companion will have 9).

Leveling Companions: Companions can level up. They gain XP for fighting, fucking, and being impregnated or impregnating should they be male. They level up with the same XP a player would, starting from level 1. Can start higher under the DM's discretion, of course. When they level up, they can either be given their average health again (Goblins gain +9) or rolled, being the same dice for health the creature has +2 (Goblins would gain 2d6+2). They also gain +1 to one stat of the players choosing. The companion can be given gear as wanted by the party. The base damage the creature does is based on their weapon and STR or DEX depending. Usually, they start with weapons as stated in the monster's stat block, but this can change depending on the party or DM.
