Incubus/Abilities/Bypass cervix

Bypass cervix: Incubus ability

This power creates a number of magical effects during sex, all of which promote more of the incubus' semen entering partner's uterus and less of it leaking out.

• Foreskin adherence: During ejaculation, incubus' foreskin will stick to the walls of partner's vagina in a nature similar to a vacuum seal, thus preventing back-flow of semen. (Invalid if incubus is circumcised) Especially large ejaculations can overwhelm this seal. This effect can be partially mitigated by effects which make it easier for the excess semen to get past the cervix. This effect is broken if incubus begins making large movements with their penis post-ejaculation.
• Magical back-flow barrier: Incubus' penis has a magical barrier around the head absolutely preventing their semen from leaving partner's vagina so long as the incubus still has their penis inside. Has all the same benefits as foreskin adherence, but cannot be rendered invalid by lack of foreskin or overwhelmed by large semen volumes. Can only be broken by incubus completely removing their penis from partner's vagina. (Replaces foreskin adherence upon acquisition)
• Negative pressure uterus: Creates a negative pressure inside partner's uterus that exceeds the uterine suction created by female orgasm. This pressure triggers in response to incubus' semen being in partner's vagina, and continues so long as the incubus' semen is present in the vagina and outside the uterus.
• Minor cervix dilation: Cause partner's cervix to dilate just a little to more easily allow semen to pass, but not enough to allow the actual head of the penis inside. This is a magical effect that activates during sexual penetration.
• Unobstructive cervix: Ejaculated semen will pass through partner's cervix as though it's not even there, thus allowing all of the semen to spray directly into partner's womb as though the cervix was being penetrated. Holds all the insemination-related benefits of cervical penetration without the risks of compromising partner's reproductive health. (replaces minor cervix dilation upon acquisition)
• One-way cervical plug: Creates a magical barrier on partner's cervix that allows semen to pass into the uterus, but keeps it from exiting. While this effect usually would not matter due to the miniscule trickle of semen that normally enters the uterus, combination with other incubus powers can create situations of high semen fluid pressure inside the uterus. Under these conditions, none of it will leak out. (New semen can be rejected if there is a lot of semen already present in uterus. The amount that will cause this to happen can be slightly raised if combined with negative pressure uterus.)

Conditions:

• Male
• Incubus
• Take measures to prevent semen from escaping partner's vagina
• Take measures to force more semen into partner's uterus
  • (Foreskin adherence): Incubus is uncircumcised
  • (negative pressure uterus): give partner an orgasm post-ejaculation or simultaneous with ejaculation
  • (minor cervix dilation): Have an ejaculation large enough to break foreskin adherence
  • (Unobstructive cervix): force 1 tablespoon of semen into partner's uterus in under 10 seconds
  • (One-way cervical plug): force 1 tablespoon of semen into a single partner's uterus in under 2 days
• Minimum number of partners - 1

• Power requirements - varies by effect
  • Foreskin adherence - 5,000
  • Magical back-flow barrier - 50,000
  • Negative pressure uterus - 1,000
  • Minor cervix dilation - 50,000 (5,000 if incubus has ever had their penis penetrate a partner's uterus)
  • Unobstructive cervix - 100,000
  • One-way cervical plug - 10,000

(All requirements cut by 90% if incubus has acyclic impregnation)
