NPC Pregnancy & Couples

NPCs can go through the same cycle and pregnancy system as the player. Key settings:

Setting	Default	What It Does
NPCs Can Become Pregnant	On	Global toggle
NPC Feel Pain	Off	NPCs get pain effects
NPC Born Child	On	NPCs actually spawn child actors
NPC Have Items	Off	NPCs receive hygiene/contraception items via scripts

NPCs near the player are scanned periodically and given the cycle tracking spell. Their pregnancies progress in the background based on game time. Only NPCs that actually exist in a plugin are picked up this way -- runtime-spawned generics (leveled bandits and similar temporary actors the engine later deletes) are skipped, which keeps long saves free of orphaned script data. Spawned actors serving as your followers are the exception: they stay fully tracked.

To keep the tracked-NPC list from growing without bound over a long playthrough, an NPC the player has not been near for 3 in-game days is quietly dropped from active tracking, and re-discovered with a fresh cycle the next time you meet her. Cleanup never touches a woman with anything in progress -- she is kept while pregnant, in labor, recovering, miscarrying, on contraception, or carrying sperm. The only visible effect is that an idle, non-pregnant NPC's exact cycle position is not remembered across a long absence; pregnancies and conceptions are always preserved.

When baby spawn mode is "Item/Actor" and you are the father, an NPC mother will hatch the baby item she carries into her own child (a normal NPC near her, not your follower) once it matures while she is loaded -- see Baby Items Growing to Children.

Conception from NPC↔NPC Sex Scenes

Besides the background auto-insemination below, a tracked NPC can conceive from an on-screen sex scene with another NPC. Both SexLab and OStim NPC↔NPC scenes are hooked: when the penetrating actor climaxes in a vaginal action, the receiving female is inseminated exactly as if the player were involved. For OStim this covers its own aggressive/NPC scenes and scenes driven by OStim NPCs - NPC Sex Lives Improved, so an OStim-populated world produces pregnancies on its own. This uses the same validity rules as everything else (NPC must be relevant per your MCM settings, not on contraception, no chastity belt, and so on), so no separate toggle is needed.

NPC Auto-Insemination (Couples System)

When enabled in MCM (Impregnate page), the mod can automatically inseminate tracked NPCs in the background -- even when the player is not around. This models background conception between paired NPCs so their cycles progress without the player present.

How it works: Once per in-game day (at a configurable time), the system queues several random tracked females (the Count setting) and works through them a few per game-hour rather than all in one frame. This is best-effort -- any not reached before the next day's check are simply skipped.

Partner selection is weighted by relationship:

Source	Weight	Description
Husband	10x	Vanilla spouse or manually assigned via Couple Widget
Affairs	4x	Assigned via Couple Widget
Partners	2x	Assigned via Couple Widget
Last Seen NPCs	1x	Males the female was recently near (automatic)

A male is picked randomly from this weighted pool (e.g. a husband is 10 times more likely to be chosen than a random nearby NPC). The system tries up to 3 times to find a valid male.

Fallback when no partner is known: if a female's pool is empty (no husband, affairs, partners, or recently-seen males) and Last Seen NPCs is enabled, the mod falls back to a random valid male in her own current location -- so an NPC with no configured relationships can still be inseminated by whoever happens to be nearby, subject to the same validity rules below.

A male is valid if:

• Not in the player's current location
• Not a player follower
• Had sex more than ~7 hours ago (cooldown)
• Relationship rank is neutral or better (not an enemy)
• Not a creature (unless creature sperm is enabled)

Couple data is stored in JSON files at Data/BeeingFemale/Couples/. Each file is named ModName_FormID.json and contains husband, affairs, and partners for one female NPC. You can edit these manually or use the in-game Couple Widget. The exact file format and bulk-import behavior are documented in Couples Import.

Couple Widget

The Couple Widget is a debug/editing tool for managing NPC relationships in-game. Enable it in MCM under the System page.

Hotkey	Action
E (hold 1.5s)	Select a female NPC as subject
H (hold 1.5s)	Assign or clear husband
G (hold 1.5s)	Add or remove affair partner
P (hold 1.5s)	Add or remove regular partner

The widget auto-detects existing vanilla spouses (relationship rank 4+ or Spouse association).

Couples Import

You can bulk-import couple data from JSON files via MCM (first page, "Couples Import"). This scans Data/BeeingFemale/Couples/ and applies stored partner data to matching NPCs.

MCM Settings (Impregnate Page)

Setting	Default	What It Does
Active	Off	Master toggle for NPC auto-insemination
Husband	On	Include husbands in partner pool
Affairs	On	Include affairs in partner pool
Partners	On	Include regular partners in partner pool
Last Seen NPCs	Off	Include recently nearby males
Time	Configurable	What time of day the daily check runs
Count	3	How many NPCs to queue per daily check (spread across game-hour ticks)

The recently-seen-males list (the 1x pool source) is populated using powerofthree's Papyrus Extender; without it installed, that list stays empty. The husband/affairs/partners pools and the same-location fallback do not need it.
