About This File

This version contain fixes for almost all content from episodes of the original Sexout Breeder, but the goal was to restore the Deathclaw route, so if you will notice bugs in other episodes, just notify me about that and maybe we can find a way to fix it.

Coming back to the Deathclaw route; it has a lot of improvements to storytelling, level design, background stuff and it contains a lot of new content for the story.


All Deathclaw route content from Riverside and beyond contain a LOT of sex so PLEASE SAVE OFTEN (casm), because bugs like vanishing NPC's and stuck tokens can happen.

If you get lost, you can try to check the walkthrough section. It has walkthroughs for almost for all episodes. (But it does contain spoilers)


This plugin features a series of stories and encounters that lead the player to get ambushed (or sometimes tricked) into situations, that lead to impregnation. Usually with the various mutated animals around the mojave. Also features a tiny amount of domination, some player slavery and a hint of (mostly) optional transformations ( including deathclaw, giant ant, bloatfly, wolf, and breast growth). I do not condone any of the explicit concepts explored in this plugin and believe they should remain in the land of fiction. But they are very entertaining to play in a video game, so have fun.


To install Sexout Breeder successfully you must first install ALL of it's requirements & ALL the requirements of the requirements. After all requirements are installed it's a matter of using your preferred mod manager (MO2, Vortex) to install the full version. Because of size limits, the download comes in 2 parts. Future ESP-updates may come as seperate downloads, to be installed over the big files.

WastelandExtended.esp (Removes invisible walls. Causes NavMesh conflicts in Nipton, causing forced dialog to fail triggering - Mod no longer available on Nexus)

"For the Enclave" has multiple issues with factions and landscape changes that directly conflict with the Deathclaw episodes.

YUP - According to Daniel5152: "Spunk, Pregnancy, SCR, MPO. and Breeder are all working fine, I'm using the latest Breeder esp and I'm getting dialogue boxes after I clean each item in the sheriff's house, So it was YUP that was overwriting Spunk, Pregnancy, Breeder and MPO.  If fellow members are still having problems have them re-install the above Mods overwriting everything.and that should fix the issue"

Morgan Town places a shack in the middle of the super mutant compound.

If you'll find more, please notify me


If you have a feeling that a character has stuck SexoutTokens, you can use SexoutSexKey to engage the NPC/Animal in Sex. If it doesn't work, it has a stuck token and you should go back to a save, before it had sex.


If you need help with installing, you can follow this guide


Step 1:NVSE Get version 5.1b4 or newer

Step 2: Get a mod manager. FOMM is suggested on this site, but I personally prefer Mod Organizer
https://www.nexusmods.com/skyrim/mods/1334/?  (it says Skyrim in the link, but it works for Fallout 3,New Vegas and Skyrim)
Here's a huge guide to get Mod Organizer set up:
http://wiki.step-project.com/Guide:Mod_Organizer (I understand if you don't want to read everything, but chapter "Initial setup" should be followed)
Step 3: get LOOT, to sort your load order
Open Mod Organizer. Click on the 'Gears' button. browse to the location where you installed LOOT (Make sure you have the 'Use Application's Icon for shortcuts' checkmark selected) and press 'Add'. Now you can and should always run LOOT from Mod Organizer.

Step 4: Get FNVEdit. Even if you are never going to edit plugins, it's a very good way to find mod conflicts, missing mods nad mods being loaded in the wrong order.
Again. Make a shortcut in Mod Organizer so you can run FNVEdit from Mod Organizer. Otherwise you'll get funny results.

Step 5: Fallout New Vegas is a 32-bits game, and can't handle more than 2 GB of memory. WE WANT MORE.  This makes the game able to use more memory
it also requires "VC++ Runtime Redistributable x86" which is linked on the same page. Just place the 4GB patcher in the game folder of New Vegas and run the program, and it should update the EXE. Note that everytime you have Steam verify the game cache, it will revert the exe to 32-bits. So repeat after every 'Steam verify'.
You can also use https://www.nexusmods.com/newvegas/mods/55061

Now we have all external programs installed, so we go to the section of making New Vegas more stable and less buggy.
For all Nexus links, if possible press the 'Download with manager' button, in order to get it in Mod Organizer. It saves you some time.

Step 6: Install "Yukichigai Unofficial Patch - YUP". This mod fixes a huge number of bugs from Fallout New Vegas and it's DLCS. From flying trees, to broken quests.

Step 7: JIP LN NVSE Plugin. This expands the NVSE to be able to use even more functions.

Step 8: New Vegas Tick Fix, Improves performance and reduces 'stuttering'
Step 9: NVAC - New Vegas Anti Crash. Reduces the chance of getting a 'Crash to Desktop' or hanging system. It does not completely solve it, but reduces it greatly.

Step 10:The Mod Configuration Menu  (MCM). Requirement for Sexout-mods and other mods.

Step 11: CASM with MCM. Does your auto saving for you, without causing the game to crash (hopefully).

Step 12: UIO - User Interface Organizer. To get all User-Interface mods to work together.

Final preparations before we can get started:
Step 13: Compatability Skeleton - BnB BodyExtender FAFF NVG. A skeleton that has all features we need for Sexout (Penis, boobs, pregnant belly support)
--- Make sure this mod is never overruled by another mod!!!

Step 14: Smallertalk. Makes unvoiced dialogue visible.

Step 15: NVSE Extender (aka NX). Even more functions to add to NVSE. These are aimed at the Sexout-functionality.

Now we can finally install Sexout....
Step 16: SexoutNG - Stable Release '97 2.10.97. Get the 'SexoutNG - Data 2-10-97.fomod', 'SexoutNG - Core 2-10-97.fomod' and 'SexoutNG - Bodies 1-1-1.fomod'

Step 17: Sexout Resources https://www.loverslab.com/topic/22156-tutorial-scr-resources-folder-creation/


Step 18: Sexout Spunk 1.01.04 (20171229) or newer. In order to get 'sperm' functionality. (Mod is being updated a lot, so you might see a newer version. Just get the newest one)


Step 19 You could install Sexout Pregnancy, Sexout Offspring, and dozens more mods, or be lazy and install: SMMP (Sexout Maternity Mega Pack) 20180201.3 or newer. This contains a ton of pregnancy, offspring and maternity wear related mods, all in a single huge package. If your machine is more than 8 years old, it might not be able to handle this, as it's quite a drain on the system.

Step 20. Sexout Breeder: The ultimate goal.


Download and install the Sexout Breeder plugin with the all resource files from the download page.

Now run LOOT through Mod Organizer to get the loadorder sorted.
1: Now load up NVSE_Loader through Mod Organizer. It will take some time before the game is loaded in, so it's a good time to make some coffee.
2: Start a new game, or continue a save game (not recommended)
--- In case of a new game. 'get out of bed' (Finish the generating character bit). You might get an error message from Spunk, before you leave the bed. Just click it away. It gives an error, because it needs Sexout Pregnancy to load, and Pregnancy loads after it knows you're female/male. ie. Sexout Spunk/Pregnancy will fix itself.
3: press escape and do the following steps:
--- 1: Go into the game-->Settings-->Gameplay and untick all 'Save On ...". CASM is now handling your auto saves and is much better at this.
--- 1B. Settings --> Display.  Enable both the 'General Subtitles' and the 'Dialogue Subtitles'
--- 2: Go to Mod Configuration --> SexoutNG--> Rape KOs and either disable the Rape KOs completely or set the time of the KOs equal for attacker and victim (2 seconds I recommend).
---2B: Go to Mod Configuration --> SexoutNG--> MISC and tick 'Enable Placeholder Animations'. You might also want to change the gender Sexuality and 'hole' preference here.
---2C: '''' --> '''' --> General. Untick Limb damage (not a hard requirement, but I personally don't like this feature)
---3A: '''' --> SexoutCommonResources --> Extra Companions and Clothing. Select all
---3B: '''' --> '''' --> Plugin Settings. Drug Duration to 100% (if you have Sexout Drugging installed, and if it isn't 100% already)
---4A: '''' --> Sexout Pregnancy --> Fertility Settings. 'Female Fertility Enabled' to 2 or 3.
                                                         'Player Female Fertility Cycle Days' and 'NPC Female Fertility Cycle Days' to somewhere between 3 and 7 days.
                                                         'Cum Bloating'. I usually have this set to 100+, but that's my own preference
---4B: '''' --> '''' --> Pregnancy Settings. Non-Human Pregnancy to 3
                                             AndroidRace Fertility Enable to 3 (Not a requirement, but a preference for me)
                                             Adjust Pregnancy Length to 3% or more. 7% or more for the Bloatfly episode. Unless your patient and don't mind waiting for weeks, I suggest reducing the number of days for pregnancy to finish to the minimum. If you go below 3 you'll get all kinds of errors, so don't do that.
                                             Miscarry change, Multiple Conception chance and Mutation change all to 0. (Sexout Breeder doesn't take miscarriages or other alterations into account and can bug out in that way.
                                             Maximum Belly Size to 7 (default setting)
---4C: '''' --> '''' --> Birth/Offspring settings. Offspring Paternal Instinct to 100%. We don't want your babies to attack you.
                                                   Offspring growth speed I usually decrease to double the pregnancy length, but this is all related to your own preferences. Don't make it too short as some scenario's require an NPC to take away the eggs/pups/calves before they hatch/grow to big 
----5A: '''' --> Sexout Spunk --> Spurts: Tick 'Always use water sources' (Preference for myself). Removes the pop-up when you drink water.
----6: '''' --> Sexout Breeder --> Quest settings. You can make the episodes more difficult by ticking all of the hard-mode options.

Now you are ready to play the episode or episodes of your preference. It's not required to create a new character per episode as mutations are made to work together.


How to Report a Problem:


First make sure you have ALL Sexout Breeder's requirements installed & ALL those mods requirements as well then you should try to repeat the glitch. Load an earlier save and try it again. Sometimes a restart fixes the issue.

If something still isn't working, try disabling all your other mods so that your load order looks something like this:
    [X] FalloutNV.esm
    [X] DeadMoney.esm
    [X] HonestHearts.esm
    [X] OldWorldBlues.esm
    [X] LonesomeRoad.esm
    [X] GunRunnersArsenal.esm
    [X] TribalPack.esm
    [X] MercenaryPack.esm
    [X] ClassicPack.esm
    [X] CaravanPack.esm
    [X] Sexout.esm
    [X] SexoutSlavery.esm
    [X] SexoutCommonResources.esm
    [X] SexoutPregnancyV3.esm
    [X] SexoutOffspring.esm
    [X] The Mod Configuration Menu.esp
    [X] SmallerTalk.esp
    [X] SexoutSpunk.esp
    [X] SexoutBreeder.esp

If that load order doesn't work, tell me everything that happened up to when you ran into the bug & use the 'Create Debug File' option in the MCM menu.
Unless you're a regular in the thread, if you report a problem and your post doesn't contain the debug file, I will assume you haven't read the FAQ. I want to help fix your problem, but that requires work on my part, and the least you can do is make my job easier.



Frequently Asked Questions:    


If you have a question, check here first. It might be answered.

    Q: Why is the bloatfly feeder crashing my game?
    A: Probably because you're not using NVAC. Please check the requirements section.
    Q: The farm slave outfit isn't appearing correctly for me.
    A: If it's completely invisible you need to redownload the maternity clothes pack. If it's flashing textures, you need the texture found here
    Q: Why do I have red exclamation points in my game?
    A: You didn't install something correctly and you're consequently missing a mesh file. Notorious issues are related to incorrectly installing Sexout Common Resources or the Sexout Breeder data files.
    Q: Why is [insert item/npc here] invisible?
    A: You didn't install something correctly and you're consequently missing a texture file. Notorious issues are related to incorrectly installing Sexout Common Resources or the Sexout Breeder data files
    Q: Lucy/Sam/Some other NPC disappeared. I can't do anything.
    A: Look around really good first to make sure they aren't just hiding from you. If you're 100% sure they're gone, check the mcm and find the option that's called NPC Fixer. It can restore almost all quest npcs. If they are not in the list please notify me in the support topic. Sometimes NPCs will disappear during/after sex & you may need to reload a previous save(please save often). Even if you manage to restore a NPC, the NPC might have stuck tokens. So best is to make a seperate save and check if you can engage with that character in sex. If that works, you can reload the previously made save, otherwise you'll need to restart the game and go back to a save, before the character disappeared.


Detailed Description:


Note: It is recommended to set your Pregnancy length to at least 3% for bighorners and 7% for bloatflies otherwise weird things can happen. Only set fertility to Player and followers (and future followers), but don't set it to 'all NPC's' as that will remove similated pregnancies from characters and break immersion. Also don't forget to enable pregnancy by animals.


Another note: If you would like to contribute to one of these walkthroughs please pm me. I don't necessarily have time to go through each scenario in depth and write a walkthrough for it. Also some of the current walkthrough can be a copy-paste from the older version and be inaccurate.




The first post/download page is already so big that the walkthroughs didn't fit on them. You can find updated walkthroughs on post #2.

New reworked lactation system:


Short description
It adds lactation that depends on your type of pregnancy and causes your character to produce milk. More milk gives bigger breasts. Bigger breasts requires more milking. Milking gives you bottled milk. Repeat.


How it works

If your char is pregnant, the Lactation script will first check what pregnancy your char has and determines the milk multiplier.

Insects(ant, scorpion, etc) - 1x
Medium creatures(i.e. gecko, nightstalker and canines) - 2x
Any kind of child(human, ghoul, mutant, etc) - 3x
Bovine and artiodactyl (brahmin, bighorner) - 4x
Deathclaw - 5x


Total modifier counts by summing and dividing all pregnancy's type count: For example, character has an ant and deathclaw egg, then the modifier will be equal to 3 ((1+5)/2)


After this, it will check your current pregnancy percentage, and on x% it will start the lactating process. If x% is set too high, like 100%, the lactating will start if your birthing is in progress.


When the Lactating process is started, at every refresh interval (1 hour by default), it will start to add some amount of milk, that will be multiplied by the milk multiplier. But don't worry if you sleep or wait to much, as it will check the difference between the passed time and the time that was needed for the refresh event, and give you all the milk for the skipped hours.


Breast scale
Breast scale depends on how much milk you have and with this formula (1/Max Breast Size * Max Milk Amount). It means that if you set the max milk amount to for example 1000ml, you will easily gets the biggest size of breasts.


Milking by default needs the amount of milk that's equal to 1 size of breast. example: Max Milk Amount=20000 and Max breast Size=1, then for one time milking it will cost 20000ml(all) of milk that you have.

But you can also change what amount of milk you will milk, by changing the Milking Multiplier. The Milking Multiplier can be set between 0.1 to Max. The Max value is determined from max breast size.


When does lactation stop?
After your character gave birth, a timer will start, that's equal to 6 days(by default). After the timer is finished, milk producing will be divided by 2 and another timer of 1 day is started. After this timer is finised, it will again be divided by 2, and a third timer of 1 day is started. After this third timer is finished, lactation will stop.


For giving your favourite follower some mutations. (Note. Sam can get Deathclaw mutations in game)


Click on the Female npc in the console and type:

Add the following. If need add more, just repeat it with another value. If need to increase/decrease the level, use the same value of Type

NX_SetEVFl "SOB:MutationTypeX" x ;Where x - Mutation for adding: 2-Deathclaw, 3-Wolf, 4-Ant. 
NX_SetEVFl "SOB:MutationLevelX" x ;Where x - Level for mutation: DC 2-7 (exclude 1, 6), Ant 1-5, Wolf 1-4
cios xx033c56 ;Where xx SOB id from LO, Add spell

To remove mutations

NX_SetEVFl "SOB:MutationTypeY" x ;Where x - Mutation for removing. 2-Deathclaw, 3-Wolf, 4-Ant. 
cios xx033f57 - Remove spell



Now about the future of the mod. We (Neutron, 1trevdog1 and Dborg2) have a lot plans for the expanding the deathclaw route as much as you will be complete the game through the deathclaw episodes. But adding all these plans is a daunting task for us, so if you want to help us with continuation of the mod, we will always accept any help that you can give us.


Final Notes from Neutron
We worked so hard restoring the original content for Deathclaw episodes, by added a lot of new content and restoring the original ones. Dborg2 also helped and still helps me to improve it with new cool dialogs or just more enjoyable additions. It was really hard to make it to a release state. So, I think you will be enjoyed a lot with new stuff that was added during this period of time.

We are always looking for more testers for the content, especially the deathclaw content. If you would like to contributed screenshots, walkthroughs or volunteer to test the content or maybe be you want to be a part of us and helping with a new cool ideas and stuff, just pm me or Dborg2.



Also, We have an our Discord server for getting any kind of information about the mod, getting support and just random fun stuff.
