OSC-Based Fertility system
Tags
Product Description
This is a fertility system that lets you get impregnated by someone else and have the pregnancy progress in real-time.
It uses an OSC program that will at some point be sent to windows to verify its non-virus status, so you might get a warning. Windows Smartscreen will basically tell you that it doesn't recognize the OSC, but it's not a virus warning, just windows telling you to be careful with unknown programs.
OSC (8) seems to have been flagged as a trojan which isn't the case but for those who don't wanna ease their antivirus, I uploaded a debug version
Scroll down for install instructions (Notes at the bottom)
Features:
- Real time based pregnancy of up to 12 children (regardless of if you're in the avi or not)
- Cum inflation
- Risky mode toggle, allowing multiple impregnations in the same session and risking accidental impregnation
- Fertility toggle, governing whether you can be impregnated or not
- Fertility system toggle, showing or hiding the children
- Breast size increase with progression
- Lactation, can trigger randomly after 10% (can be disabled)
- Pregnancy test, will show you if tested person is pregnant or not and locally show how many children you are carrying (takes a little while before the test is effective)
- Customizable gestation period (ranging anywhere from 1 hour to 100 months)
- In-game progress bar
There's a free complementary virility system for male avatars to make impregnation easier. Link: https://jinxxy.com/Acoenonoeti/JTqdZ
Impregnation using virility system:
Either close both hands fully (fist gesture) while inside or use the override toggle in the menu
Impregnation using only SPS:
Grab the BLUE ORB on side of the waist (RED ORB for cum inflation) and press trigger (Must have a dick inside for it to work). Like posing a bone
Updates in progress

- Tutorial vid
- Clarifying what are and aren't customizable animations and putting them all in a distinct directory
!! IMPORTANT !!
The system is still pretty new and you may encounter glitches
For now there's no real way to get support with it except contacting a blender/unity-knowing friend or seeking me out.
There is a known issue where the avatar sometimes registers as impregnated upon loading it, if you encounter this you can set the "Gestation Time" slider to near 0% temporarily to get rid of the unwanted child
It is still being worked on but an older version is available that as far as I'm aware does not share the same issues.
SPS is required for both parties
Setup for wholesome SPS preset
The "input required" folders are only for custom named blendshapes
Blendshapes aren't included as they have to be part of the model
Some blender knowledge is therefor required
Blendshapes needed (case sensitive):
- Pregnancy
- Twins
- Multiple Pregnancy (10x)
- Cum belly
if you only wanna carry one you need only the pregnancy blendshape
Pregnancy blendshapes are compounded, i.e. twins will progress while pregnancy is still at 100%
Install instructions
- Drag the prefab (Preg OSC > MAIN) onto the Pussy SPS Game object as a child
- Click on the pussy SPS object and add a new Active Animation "Object Toggle" to the VRCFury SPS component (found in the inspector if you select the Pussy SPS in the Hierarchy)
- If you don't have wholesome SPS you will need to also add a Depth Animation with Set an FX Float and type in "WH_SFX_Depth"
- Drag the "cum stuff" Game object in the hierarchy (child object in the prefab) into the Object Toggle slot
(Optional)
- Find the "Milk tits" animation clip (Preg OSC > Input Required) and animate it to grow your breasts in whatever manner you see fit. The animation will progress at the same speed as the pregnancy
- Find the "Birth animation" animation clip, add in anything you want to happen during childbirth in the animation clip and it'll play out fully before resetting. (Egg model exists in the project but no setup)
There are lactation and pregnancy test prefabs that are mostly drag, drop and realign.
For lactation:
- Drag the prefab onto the basic avatar hierarchy
- Align left and right target objects to the nipples
- Unpack the prefab and drag the target objects as the child of the respective nipple's bone
For pregnancy test:
- Drag the prefab onto the basic avatar hierarchy
- Move the test object (child of the prefab) to be visually placed in the right hand, rescale if needed
- Move the hip contacts beneath the hip, it's fine if it's somewhat big, typical scale would be about from the crotch to a bit below the knees and from middle of left leg to middle of right
Notes
- The system doesn't necessarily have to be on the pussy but can be used on any SPS object so long as it's parented to it with the required active and depth animations, which means YES, you can do anal impregnation and as a male. I do however not recommend putting the system on the avatar more than once but instead using a VRC Parent Constraint to move it around (can use active animations set to animation clips for ease of use)
- The gestation time slider does have a failsafe so that you don't accidentally put it to 0% and kill all the children, so any attempt will be ignored but you can put it to near 0% and have the pregnancy end early to reset it. It wasn't originally like this but it proved necessary after hearing about people accidentally deleting their children a bunch -w-
- Gestation time is determined by the "Timespan" and "Gestation Time" slider in the "Time Lord" menu. It's connected so that for each 1% on the Gestation Time slider, it'll last 1 of the corresponding timespan setting. (i.e. Gestation time = 9% and Timespan = Months, then the pregnancy will last for 9 months)
