Wicked Traits Unleashed (WTU) Early Access v1.x
Your Sims have preferences. Now their traits can act on them.

They can affect attraction, commitment, location changes, animation intensity, protection, and whether a couple is ready to stop after the first round.
This is the Early Access version.

The Traits
🥰 Aftercare (⭐New Trait)
What happens once the encounter is over?
Aftercare gives partners a chance to stay close, freshen up, talk, relax, or ask for a little space.
Depending on what is available, this can include things like showering together, cuddling in bed, massage, watching the sky, staying the night, and talking about what happened.
💋 Irresistible Body
An Irresistible Body Sim attracts attention without asking for it.
Nearby Sims can become distracted and unlock four custom Romance socials.
Partners receive special moodlets during an encounter and may continue thinking about the holder afterward through Can't Forget Her or Can't Forget Him.
The trait also keeps the holder's sculpted physique from drifting over time.
(No Fat Loss/Gain or Muscle Loss/Gain)
💍 Oathbound
Oathbound makes commitment part of actual gameplay.
In Bound mode, Sims refuse encounters outside their committed relationship.
In Temptable mode, Sims can be approached with Try to Seduce. Attraction determines whether the attempt succeeds, and only that specific pair receives an opening.
(You can switch between Bound or Temptable gameplay modes via WTU settings)
If they go through with it, the trait remembers whether the vow held, nearly broke, or was shattered.
Temptation's Pull can be set to Guarded, Balanced, Reckless, or No Resistance.
[NEW] You can also allow as exception via Sim Menu -> Oathbound -> Allow an Exception
🔥 Wanderlust
Wanderlust Sims get tired of staying in one place.
During an intimate encounter, the trait can find another compatible location nearby and continue the same session there.
In Ask first mode, you choose from up to three destinations. Automatic mode lets Wanderlust decide. NPC-only couples can move automatically as well.
(You can choose a 10%, 25%, 50%, or 100% activation chance and allow up to three moves per encounter. All configurable via WTU settings)
🔥 Second Wind
Sometimes the first round only wakes them up.
After an encounter ends naturally, Second Wind may invite the same partner into one fresh session with new timers, progression, and animations.
Player-controlled couples can receive a two-portrait prompt:
I'm not done with you yet. Think you can handle another round?
Choose Come prove it or let them catch their breath. Automatic mode skips the prompt, and NPC-only couples can use it too.
You can control the activation chance and choose no cooldown, six Sim-hours, or twenty-four Sim-hours.
Second Wind allows one extra round only. It cannot continue forever.
🖤 Hardcore Heart
Hardcore Heart Sims prefer their encounters intense.
During automatic progression, the trait can favor compatible rough, or other similar contextual animations. (You must have these types of animations installed separately)
The trait changes the context without forcing the encounter to skip ahead.
Qualifying animations apply Do Not Go Gentle Into That Good Night moodlet to the holder and No Holding Back to their partner. If the encounter stays too gentle, the holder may leave frustrated instead.
(The intensity chance can be set to 25%, 50%, 75%, or 100% via WTU settings)
🐾 Bare Instinct
Bare Instinct turns protection into a decision that can happen during the encounter.
Once things heat up, a holder may ask their partner to remove the condom. The partner can accept, refuse calmly, or make it very clear that the request crossed a line.
If accepted, protection stays off for the rest of that session. Pregnancy risk is checked again when appropriate, so removing the condom can actually matter.
(Ask first and Automatic modes are available, along with a 25%, 50%, 75%, or 100% activation chance - configurable via WTU settings)
Accepted encounters can apply certain moodlets. Refusals have their own reactions too.

They can work together
The traits remain independent, so combinations can create very different nights.
Wanderlust may move an intense Hardcore Heart encounter somewhere new. Second Wind can begin another fresh round afterward. Bare Instinct may create a new protection decision once that round heats up.
WTU does not replace normal WickedWhims progression. It gives the traits opportunities to influence it.

This is one of my most ambitious gameplay mods so far. I wanted these traits to create stories, not just sit quietly in the Simology panel.
Have fun and let me know which trait combination causes the most trouble in your game.

does the early access version, like, have more content than the public release, but also include all the stuff from the public version updates?
Yes! There are 3 extra traits currently in the early access version, more coming soon!
The Aftercare bed scene was so sweet—I loved the animation! 😊 But when the Sims got up, they were still naked. I have WickedWhims set to “Auto Dress Up After Sex.” Could the Aftercare trait use that setting to dress them?
Yes! Can do, although it might be a little brittle/flaky since the interaction observer I currently have(which detects if the interaction has successfully completed) might fail sometimes to detect completion.
Right so this is something I noticed repeateadly in a pattern, Ive set everything to automatic, and the locations and animations are pretty much repetitive. I can tell and know where the sims are . Its a back and forth of 2 or 3 locations with same animations despite having way more animations
Interesting, will investigate this. Is this the Second Wind trait or Wanderlust trait?
Hey, I just got a Better Exceptions report on WW because I formed a casual sexual relationship after loosening the oathbound trait on a sim allowing a third sim to act how he wanted. I'm pretty sure Turbo will say his mod is okay. It's been okay since May. Is this something I just need to avoid doing or is it fixable on your end? I appreciate your input on this. Absolutely love this mod.
I’ll check this and fix if required ! Will update here once done, thanks! Possible to share the exception?
After updating from 1.0.5 to 1.1.1, Second Wind stopped working—and After Care certainly isn't working either. :( I'll send you the log.
Thanks
love your mod, but my game won't load with this recent update
Hi! Did you try the older version 1.1.0 or the new 1.1.1? This has been reported a few times, so wanted some more info
Impressive!
your awesome!!!!!
No, you are awesome!
Thanks so much for the great treats! You really put a lot of effort into this. I have a question: Do you have to give the treats to all the Sims you interact with, or just the one you're playing?
Thank you so much for trying out my mod! As of now, most of the traits work if one of the active Sim (who is taking part in the WickedWhims intimate session) has that trait. For traits like Irresistible body, anyone who comes in proximity to the holder gets the buffs, provided they are an eligible pair.
This is FANTASTIC! Hardcore hearts is my personal fave, I was wondering if there might be a way to keep predetermined animation sequences going when the trait picks a rougher animation. I like when the scene keeps its flow and I realize the traits just keeps picking at random
If you are using a playlist to initiate the animation, the trait chooses from within the playlist. For normal flow, can you elaborate on the randomness. Was it too out of tune with the rest of the animation flow before it? Would be interesting to understand how the session started and what was the last animation before which the trait changed it to rough context.
Wow, XtremSyn, you are ABSOLUTELY INCREDIBLE! 🤯⚡ I can't believe you coded and released this masterpiece of a patch so fast! These patch notes are pure gold. Adding the medical whitelist AND the "Loosen the Rules" social interaction with the 24-hour persistent exception is a dream come true for storytelling! Plus, fixing the "Second Wind" prompt loop is amazing for my other couples too. I'm opening the game in a little bit to test the new mechanics and see the doctor's visit run smoothly. Thank you so much for being such an awesome developer and listening to the community. You rock! ❤️🏆
Thank you, this was for you! Thanks for giving me feedback!
I had a lot of fun with this traits! By saying that I want to ask you if there is any plan to create a trait that the sim who has it will reject any X proposition if he/she is not in relationship (bf, gf and above)
Doesn't the Oathbound trait already cover that requirement, or am I understanding it wrong? A Sim with Oathbound trait blocks romance with anyone else as soon as they are committed to someone. Although the twist is that someone else can break that if playing in Temptable mod - the interaction is manual so won't happen automatically. Another variation is the WW's Eternally Faithful trait which blocks all romantic interactions until you marry them.
Hey, this is really cool. I love it, but menu options like "Nobel Introduction and Propose Alliance" to name a few for the R&L pack disappear completely when your mod is installed. I take out your mod the interactions return. It was the only change I made and I tested it twice to made sure. It happens for all Noble sims whether they have any of the wicked traits or not: they lose some of the noble interactions.
Thanks for reporting this, I'll check and post an update here once fixed!
wow that Bare Instinct trait sounds exactly like the "controlled randomness" I mentioned! Where have you been all this time for sims NSFW mods?!?! Would a dialogue choice based sex progression mod be possible? For example you start with making out (teasing sex) and one of the sims ask to do more like oral or sex or even go from vaginal to anal and your sim can allow it or tell him to hold off. Or something like a virgin trait that requires the sim to approve going all the way along with accompanying moodlets for those.
Great idea, will keep this in mind
Please, which one do you use reshade? It's amazing.
I use Ray Tracing Shaders from MartyMods (and his other shaders - MXAO, Clarity) and AMD Fidelity Sharpen shaders in ReShade. Note that it's very heavy on PC. I get around 45 FPS on my RTX 4090 at 4K resolution.
Speechless! Thanks so much
Thank you! for the support and for trying out this mod :D
Your mods, especially this one, are amazing. Really adds that much needed flavour to the game. Looking forward to further development!
Thank you, I agree - haha. More to come!
I'm really excited for this! Can't wait to try it out :D These types of mods are just perfect for my gameplay. Keep up the good work!
Can't wait for you to try it! Let me know your thoughts :D
All your mods thus far are incredible. Fantastic work!
Tysm! Hearing this makes me so happy
thanks for this!! can't wait to play after work <333
Hope you will like it :D
Why can't I give my girl the "Irresistible Body" trait? I can't find the trait anywhere. EDIT: It is blocked for teens; could you please unblock it?
Fixed, note that WickedWhims must also allow it for this to work.
omfggg the goat thank you kingg
Thanks for your support :D
