Pregnancy

The player character can become pregnant and give birth to special items called demonic eggs. By default, the player character is infertile and cannot become pregnant.

Fertility
There are two ways to become fertile, via the Inseminal potions (of which there are two varieties) or by purchasing the traits "Maternal Instints" (for vaginal pregnancy) or "Anal Instincts" (for anal pregnancy). There are also traits for increasing the odds of becoming pregnant. Pregnancy-related traits only become available for purchase after the first time the player gives birth.

Insemination
Once fertile, the player character can be inseminated by vaginal (or anal, if the player is anally fertile) creampies. Each creampie has a set chance to inseminate the player, though the odds can be improved via traits. Only creampies that occur during encounters can make the player character pregnant. Partners may or may not creampie the player character when orgasming during sexual encounters, but the player character can unlock and purchase traits that grant her the ability to "leg-lock" partners, forcing a creampie.

When a creampie impregnates the player character, it will be reported in the description of the creampie.

Pregnancy
After being impregnated, the pregnancy advances over time, taking a few in-game days to come to term. When the pregnancy advances, a small event will occur to inform the player. After the pregnancy is complete, the player character will gain the option to give birth at her home. With the appropriate perks, she can also give birth in the backstreets or uptown. If she fails to give birth in a timely manner, the player character may randomly give birth wherever she is as an emergency behavior.

Birth
When birth is triggered, a scene will play where the player character gives birth or one or more demonic eggs. This scene changes based on your perks.

Breeding Fetish
Pregnancy and birth contribute to the breeding fetish's growth, which has perks associated with it. These perks cause changes to the birthing scene, allow the player character to beg to be bred during vaginal sex, and allow her to use the demonic eggs she births on sexual partners during encoutners.

Inseminals
Vaginal and Anal Inseminals are required to get pregnant for the first time, after which the player can unlock a trait allowing them to become permanently fertile, though the inseminals can still provide a massive boost to fertility.

Inseminals are unlocked by advancing your alchemy skill, can be purchased from Wicked Pam, and can sometimes be found in the world.

Demonic Eggs
These eggs come in two different varieties. "Male" eggs grant the player random fetish points and sexual experience in large amounts, while the "female" eggs grant trait experience. These eggs ca only be gained through birthing them!

Anal Pregnancy
Since the "pregnancy" is really just the player character using her own body as an alchemy cauldron, she can also get pregnant with her ass. Anal pregnancy is completely optional, and players can freely engage in vaginal pregnancy without engaging with the anal variant. Both forms of pregnancy are otherwise fairly similar.
