Last edit on 4/12/2022: Modify Mod Description - Updated description after 2.7 release.




Nate or Nora are great fighters (just ask Strong!) and extremely valuable to the factions in the Commonwealth.  Thus, if the player has sex then the partner of that faction may assimilate them into that faction by changing their looks or by bringing them into the faction.


This mod was made to complement mods like AAF ViolateSexual Harassment and Sex 'Em Up and is similar in some ways to mods like Tattoo After Rape and Rad Morphing Redux.


It is several small quests that mostly activate after AAF animations.  There are MCM options for script features.




After the player has sex with a partner of a particular faction there is a chance that the player's hair, body, skin, clothes, and faction may be changed.  The chance for a change to happen for each body section and for each faction is configurable through MCM.


  • Hair - Your hair will be changed to something appropriate for that faction.  Expect to get a mohawk for sex with a Raider and a military cut for sex with a Gunner.  There are differences for male and female characters.  Supported hair, beard, and pubic hair styles will also regrow over time or fall out from radiation.  There are some penalties if your hair gets too long so you should drop some scissors on the ground and use them to trim up to avoid them.  I could tell you what all the hairstyle possibilities are, but that would take away the fun and surprise.  Currently, base game/DLC hairstyles are supported plus the following mods:
  • Body - Your CBBE body will be morphed based on settings in MCM.  Configure them as you see fit, but by default it is set for female characters making the breasts and butt bigger and the waist smaller, i.e. an hourglass figure for most factions except "settler" factions which are the opposite.  It is possible to configure the settings for male and female characters.
    • FEV - If you have sex with a super-mutant, then some of their DNA may sneak into your system and cause increased muscle mass and some increased strength side-effects.  Beware!  (This can be configured or disabled in MCM).
  • Clothes - Your clothes will be changed to something appropriate for that faction.  Expect to get a harness for sex with a Raider and a suit for sex with a Triggerman.  There are differences for male and female characters.  There is an option to swap your clothing hats/helmets when combat starts/ends and an option to swap your clothing gas mask when bad weather starts/ends.  I could tell you what all the apparel possibilities are, but that would take away the fun and surprise.  Currently, base game/DLC apparel is supported plus the following mods:
  • Skin - If the Random Overlay Framework is installed then it will apply ONLY ONCE a set of random tattoos on the player from that framework.  This is a soft dependency as it dynamically checks for existence of the plugin and only uses it if installed.
  • Faction (version 2.0 and greater) - Your faction will be changed to that faction and possibly moved to a faction-friendly location.  Your last partner when spoken to will have a small dialog to initiate it.  You will remain in the faction until you have sex with enough faction members to leave the faction.  When leaving, a small dialog allows you to confirm leaving or remain in the faction.  While assimilated to the faction, you will gain a perk appropriate for that faction and sex with faction members may result in them offering gifts or to be companions (up to 2).  You will receive better gifts based on your faction reputation which increases each time you have sex with a faction member or kill a non-faction member.  It can decrease as well!
    • NOTE: Some details on implementation here: To make other factions hate the player if they become a Raider, those factions must be modified to dislike the player.  The faction relations are saved before faction assimilation and restored after un-assimilation, but there is some risk here if they never get restored properly.  I have been careful to assure that doesn't happen in the scripts, but that said I would only play version 2.0 with faction assimilation enabled on a new game not your long-term game with 1000's of hours played.
    • Post a comment if you notice an NPC is unexpectedly a friend or enemy after faction assimilation and I can likely fix it.


NOTE: There is no quick undo for the changes once they happen.  If the player's hair changes, then you're going to have to see John in Diamond City or Horatio in Vault 81 to get a new hairstyle.  If the player's body or skin changes, then you're going to have to see Doc Crocker in Diamond City to fix it.  You can put your other clothes back on if you don't like the ones given to you (the mod doesn't remove them), or some may play with mods where all your clothes are stripped and then the changed clothes will be the only ones you have!  There are easy ways to change all of these with the showlooksmenu command, but role playing and continuing with whatever changes is more interesting.


Install Requirements

  1. Fallout 4 v1.10.162 or newer
  2. F4SE - needed for lots of expanded script functions
  3. MCM - needed for extensive configuration options
  4. AAF including some themes/animations - needed to initiate changes
  5. Tested with CBBE (LMK if you have another one where it works) - needed for body changes
  6. BodySlide - needed for body changes
  7. Looksmenu - needed for skin and pubic hair changes
  8. Random Overlay Framework (optional) - needed for skin changes



  • Bethesda for Fallout 4 as without it none of this would be possible
  • The F4SE Team for their great work in finishing what Bethesda did not
  • registrator2000 for MCM a really great menu option framework
  • dagobaking for AAF and probably a reason LoversLab exists
  • expired6978 for LooksMenu making it easy to change the player's looks
  • Invictusblade for Random Overlay Framework and having an API method that could be called to apply random overlays on the player
  • twistedtrebla for Tattoo After Rape as I used the snippet of connecting to AAF from that mod
  • LenAnderson for Rad Morphing Redux as I learned how to do the body morphing from that mod
  • MxR for the mod review: https://www.youtube.com/watch?v=aGl2sOJyf88
  • Myself! as I thought it would be fun to put out a Lover's Lab mod but at first couldn't think of anything sexy enough. ?

What's New in Version 2.7




This should be able to just upgrade a 2.x lower version to the 2.7 version.  I would try to not be faction assimilated when upgrading as I think it is less risky.  Theoretically though, it should be fine as I didn't change any of the critical variables that track your membership with factions.  I did change that Rust Devils are no longer enemies of basic Raiders but this update will not fix that reputation so you would need to go back to a previous save.


The v2.7 version supports and requires the Base Game plus DLC for Nuka World, Far Harbor, and Automatron.


Fixed the following issues:

  • Rust Devils are currently made to be enemies of the RaiderFaction but unfortunately RustDevils are part of their own faction DLC01RaiderFaction and the RaiderFaction, so RaiderFaction cannot be made an enemy of the Rust Devils.  This was a must fix bug that was fixed.
  • When Assimilation Quest starts but faction assimilator dies before you talk to them then the whole Quest should be cancelled.  Fixed.
  • When faction assimilated an option "Always Affected by Same Faction" for physical areas and assimilation will control if the player is always affected.
  • Leaving assimilated faction reputation increase is added at wrong point such that if the scene actor dies before leave is complete you get the rep but stay in the faction which means you can get it again which is wrong.  Should only get it after you actually leave on good or bad terms.  Should also get it if you decide to stay in as a reward for staying.
