A refresh/rework of an adult Sims 3 mod. While this mod is relatively stable from my testing, keep in mind that I am an amateur programmer at best. Please take caution when using on saves you care about, and remember to make appropriate backups before adding this mod.

Originally by Alfiechan and updated by Superstorm/Twilightstorm until 2021, BORDEROFEXTACY_Passion is a refresh/rework of where that work was left off.

In the spirit of collaboration and cooperation, it's an open-source project -- though it currently being worked on primarily by me (Xin).

For bug reports, you may submit them on simblr.cc or Git, preferably! Please keep in mind I do this as a hobby and am often quite busy, so I may be unable to address bugs quickly.

👁 Changes from Twilightstorm's passion & Features

The following is a summary of most of the major changes from Twilightstorm's last update...

For the changelog of new features from this mod, see this mod's comments

[List updated March 21, 2026]

• Sim genitalia can now be modularly registered via a tuning file, allowing for integration with any bottom.
• For sims with penises or both sets, 'getting hard' is now handled via switching between two cas parts instead of sliders, allowing for more possibilites than just re-sculpts of the same cmar peen.
• Partial undressing
• New strap-on mesh, for Y-A male and female sims who don't have a penis.
• Sims now have 'libido', tracked through a moodlet. This increases when being romantic, and effects their willingness to accept or make proposals, as well as their end satisfaction.
• Autonomy and satisfaction have been completely redone. Autonomy factors are customizable via tuning, and sims will get a distinct satisfaction moodlet.
• Graphics have been redone, and strings and been re-written.
• Sims can be maked as 'asexual', 'abstinent', or 'hypersexual' - which will effect their autonomy.
• A handful of bug fixes.
• Vampire stuff has been removed.

For the sake of not succumbing to scope creep, I had to throttle back on what I wanted to include for the first 'public' release. However, the following features are planned for the future...

• 'Role' markers, to give sims a preference to being a top or bottom
• Modular strap-on types
• Autonomy modifiers for specific lots via buildbuy marker
• QoL stuff I missed in this release
• More bug fixes, hopefully

👁 Requirements & Installation

This mod now requires Arsil's custom trait manager!

It's recommended to use a default override nude body, as one is not included. This mod also does not come with any animations - you must download packs yourself! *BOEPassion is compatible with anything that was compatible with Twilightstorm's passion. *

To get you started (NSFW LOVERSLAB LINKS)

• OolalaCity
• Mike24
• Amra72

Simply unzip the .ZIP file into your packages folder! In the main 'folder' you can find BORDEROFEXTACY_Bodies and BORDEROFEXTACY_Settings - these contain tuning XML files you may modify to your liking!

For more thorough information, please refer to the Wiki.

For users of Twilightstorm's passion...

The download here includes everything needed - please ensure you delete your old passion files (minus any bodies or animations) as well as the scriptcache in your game folder.

Because this rework removes some elements like buffs, please take caution when adding it in!

What is the 'nightly' build?

This is an in-testing build that may not be feature complete, or is being distributed in order to test new features or catch bugs. You still need the main mod files, just delete the BORDEROFECTACY_Passion package file and replace it with the nightly version.

It should go without saying, but use the nightly version at your own risk - even moreso than the main build.
