🥚 Estrus Chaurus Reforged

Now Available — W.I.P.

The tentacles let her go. What they left behind doesn’t.

Estrus Chaurus was always the other half of Estrus — not the scene, the aftermath. Eggs. A belly that keeps growing for days. A birth she can’t stop. On modern Skyrim it was chained to SexLab, FNIS, NetImmerse Override and an XPMSE library, and it never had animations of its own — it borrowed Estrus’s.

Estrus already runs on OStim now. So this one was rebuilt on top of it: one small plugin, no SexLab anywhere, and every scene played by Estrus — OStim Edition.

What’s in this build:

🕷️ Chaurus attacks — a spit or a bite that lands on you or a follower can make tentacles burst from the ground and take her.

🥚 The eggs — when the tentacles are done, she carries them. Over the next days (3 by default) belly, breasts and hips swell, and the weight slows her down.

🩸 The birth — when it’s time, she lies down and lays them one by one. Real Parasite Chaurus Eggs, on the ground, ready to pick up. Her body shrinks back as each one comes out. Fluids and milk optional.

🐛 Infestation (off by default) — some eggs are fertile and hatch after 2 to 4 days. The hatchlings feed, grow, and once they’re big enough, they spit too.

⚙️ The Dwemer machine in the Silent Ruin, deep in Blackreach — step on its trigger and it catches you, then leaves you exhausted for hours.

🌀 Any Estrus can seed her — the shout, the encounters, any tentacle or worse set from Estrus — OStim Edition can leave eggs, each with its own chance.

🔥 OStim creature scenes too — a chaurus finishing inside her in an OStim scene can leave eggs as well.

📋 A full MCM — attack chance, who can be affected, incubation length, how much each part grows, birth options, the hatchery, a status page listing everyone carrying eggs, cure all, reset body.

🔌 The old API still answers — ECStartAnimation, ECGiveBirth, ECBirthStarted / ECBirthCompleted. Mods that called Estrus Chaurus keep working without a single change.

This isn’t a re-upload with SexLab ripped out. It’s the consequence Estrus was always missing, finally talking to it in its own language.

📦 Requirements

Skyrim SE / AE, SKSE64, Address Library

OStim Standalone

Estrus — OStim Edition 0.2.2 or newer (the tentacle, machine and creature scenes, and the birth pose — update it if you’re on 0.1.5)

RaceMenu — for the body changes

An XPMSE-style skeleton — belly, breast and butt bones

SkyUI — for the MCM

SexLab, FNIS and NetImmerse Override are not required

🛠️ Installation

Remove the old Estrus Chaurus (EstrusChaurus.esp) and its FNIS files first.

Install with your mod manager, after Estrus — OStim Edition.

Run Pandora (or Nemesis) — Estrus — OStim Edition needs it.

⚠️ Important

Start on a save that never had the old Estrus Chaurus, or one you can throw away. The old mod left its pregnancies and scripts in the save, and this one can’t clean them up.

🧪 W.I.P. — what helps most:

🕷️ The chaurus attack — does the ambush trigger, on you and on followers?

🤰 The growth — does the body change over the days, and does it come back down after the birth? If nothing grows, check RaceMenu and your skeleton first.

🥚 The birth — does she lie down, do the eggs drop, can you pick them up?

🐛 The hatchery — turn Infestation on and tell me what the hatchlings do.

⚙️ The Silent Ruin machine — does it catch you, and does the exhaustion wear off?

📜 Papyrus.0.log if anything goes wrong.

🔮 Where this is going

Everything goes into the same chain: Estrus takes her, this decides what she carries out of it. More sources of eggs, more for the hatchery, and the body work polished once the reports come in.

He doesn’t ship on a schedule. He ships when it’s right.

Thank you for keeping the atelier lit. 🖤🔧 Update Notes — Isle of Mara 0.2.7 (please reinstall)Credits

The Master taught the tentacles to leave something behind.

Three days. Then she finds out what.
