  • Per-race cum amounts
  • NPC & creature support
  • Separate tracking for anal and vaginal sex
  • Automatic deflation with random-ish intervals with a configurable minimum time before deflation
  • Hotkey for manual deflation
  • Zaz animations for deflation
  • Female on female inflation when female/female cum is in use in sexlab
  • NPC comments and status messages related to inflation

How it works

Each time any female character has either anal or vaginal sex with one or more males or creatures, some cum is added to their vaginal and/or anal cum "pool" based on the animation used and the races of the actors involved. The actual belly inflation is total of these two pools.


The config lets you set maximum inflation amount, which is also the maximum pool size for both of the two pools. It also means that the combined total cum is two times the set maximum inflation. When the total goes over the set maximum amount, the max inflation is temporarily set slightly higher than the config value to allow some bit extra inflation. Now, if it goes past that temporary maximum, you get a negative effect that slows you down and lessens health and stamina regeneration until the cum is drained to the temporary max inflation, which should happen relatively fast.



  • SexLab
  • Zaz Animation Pack
  • A body model that supports belly scaling
  • A compatible skeleton (XPMS extended for example)


Any other mod that modifies the belly node scale.


Troubleshooting & reporting issues

If you you're having trouble with the mod, or just reporting issues, you can ask for help in the thread. Remember to include your papyrus log of the events with issues. For help how to find your logs, see this thread.



Before removing the mod, uncheck "Inflation enabled" in the config menu to allow the mod to restore all the normal settings.


Supported bodies, races & issues

To get the mod working with custom races, make sure they have a body that supports belly node scaling. Most custom races have their own body model, and don't necessarily support the belly node. That means you need to copy your favourite body mod over the custom race files to get FHU working properly with them.

I won't be responding to PMs about bodies or what body mods support the scaling. You can of course ask in the thread if someone else has a suggestion.

Basic CBBE does not support the required scaling, though there are variants that do.

This would be a good place to start looking.

Note for translators

In addition to the usual translation file and the esp, FHU has an external file used for the status messages that needs to be translated as well. You can find the file in Skyrim\Data\SKSE\Plugins\FillHerUp\.
