Slutty Sister Pill — v0.1.0 [ALPHA]

View File

---

A custom-pill / event mod for X-Change Life (tested on v0.24.8)

Based on an idea by u/icy_vehicle3948 on Reddit:

 

For the next seven days you're a bimbo-brained, people-pleasing sister. Alexia finally has someone to giggle with, drag shopping, and

double-date. And Bruce... well. Bruce always gets something out of the arrangement.

 

Features

  - Scripted morning event — Alexia ambushes you with coffee. Accept or refuse.
  - Custom pill — Slutty Sister Pill, also stocked at the regular pill shop ($800) if you want to dose yourself voluntarily.
  - Continue pill — every orgasm adds a day to the timer. The harder you party, the longer you stay her sister.
  - Side effects — bimbo brain + people pleaser for the full duration.
  - Daily sister tax — Alexia takes $20-50 out of your wallet each morning for "sisterly snacks 💕"
  - Outfit override — your daily fit gets bumped to maximum sluttiness ("Alexia laid out your sister outfit").
  - Trigger gating — the event only fires if Alexia has met Bruce AND is dominant toward you / disrespects you. (You earn this.)
  - Femininity creep — each orgasm nudges your femininity stat up.

 

Bruce Addiction Pill mod integration (optional)

If you have the Bruce Addiction Pill mod loaded, additional content unlocks:  
  - Each orgasm on the pill bumps $bruce_addiction_depth — "he must have snuck that into the custom pill..."
  - Mid-week handoff — on day 3, Alexia drags Bruce over in the evening for a short scene. +4 depth, +2 days on the pill.
  - Bruce phone call on expiry — when the pill wears off, if you've built any addiction, Bruce calls. The pill's gone but the hook isn't.

  Works completely standalone without it — these branches just silently skip.

Original idea by Reddit user u/icy_vehicle3948 — full thread here:
https://www.reddit.com/r/XChangeLife/comments/1uckulj/alexia_slutty_sister_pill/ — thank you for the concept!

Implementation was done with the help of Claude Opus 4.7 via Claude Code. The integration choices, pacing, and bug-fixing iterations are
mine; Claude wrote the .twee code and wired it into the base game and the Bruce Addiction Pill mod.

The pill doesn't seem to exist? I tried to get Alexia to dose me with it, but didn't get it, and eventually went to try to buy it but this pic happens, and it's not in my pill inventory after charging me

Very nice idea!!!

Best combined with girlie training. When comes the update to xcl? Mod doesn't show up in 0.23.8...

Mid-week handoff — on day 3, Alexia drags Bruce over in the evening for a short scene. +4 depth, +2 days on the pill.

I have checked the code because I wondered why this event requires the Bruce Addiction mod, and it seems that it can happen even without that installed.

I think you should make it clear that the integration only adds the depth, because right now it reads as if the event doesn't happen without the Bruce Addiction mod.

 

I was about to post a request that you to make it available without the Bruce Addiction mod, and I'm pretty sure there will be others who will have the same idea but won't check the code first.

Just a clarification in the description should be enough. And all the best with the mod, looking forward to see where it goes in the future.

And two ideas:
- If Alexia already pills you, doesn't really respect her "step-ho", it would make sense that in the shoplifting scene she literally orders you to either pay the guard or offer yourself.

- If you ever tried the mod Alexia embarrasses you when you wear a bathrobe, after she catches her "step-ho" multiple times she starts to joke about pimping her "step-ho" out.
 

Quote

    "I don't know about that," Alexia says, "Mr. Banks, she hasn't really been doing all she could for the household recently. Maybe she should be doing more."
    She move behind you and he tosses the bathrobs to her over your head in a game of keep-away. "How do you figure?"
    "Well, Mr. Banks, it's like this. If I'm the only one not getting any around here and Madison is going to be the little cumslut, maybe I should just go all the way and be her pimp." She tosses the bathrobe back to him and your fingers just miss it as you jump. 
    "$200 and you can take her upstairs to fuck her brains out." 
    "$50". He tosses the robe back. 
    "$150". She tosses it to him. 
    "$75". "$100 and you can creampie her." "Deal". 
    "Well, Alexia, I think Madison is going to be a very good girl for me later tonight." Mr. Banks hands you back your bathrobe and winks at you. 
    Mr. Banks hands the popcorn back to Alexia, along with the money, and they share a laugh as you stand there trying not to die from embarrassment. 

 

And she actually takes the money. This could be expanded upon in your mod, it would fit in. Something similar to the existing "guy calls you" evening event, only it's Alexia informing you that someone is coming over and potentially some expectations, rules based on what the request was from tonight's boyfriend.
Could even be a "you're going on a date" event, like the Double Date mod but without Alexia. 
This could even replace the daily money drain: why rely on "maybe step-ho has money" when she can make more money by improving her step-ho's social life?

Just some ideas.

Missed a sentence.

The $pill_timer value is set incorrectly.  It is set in "ticks", i.e. time periods in the day. One day has 4 time periods

For the pill to last 7 days the code should be (set:$pill_timer to 28).

Currently it expires the following day evening.

It is a good start but needs some serious work.
The uses non-existent variables in places, for example, Alexia will never take your money because the variable $money doesn't exist, it should be $character's "money".

The pill expiration is messy, you should let the standard pill handling do the expiration, and add the mod relevant housekeeping to ::pill expire effect [around] 

The bruce handoff event doesn't really work because most of the time the $current_location won't be a room in the house, removing that check will let the event trigger.

However, the event itself doesn't do anything at the moment unless there is no next activity, in which case it moves to Free Morning which can be a bit of a problem given that the event triggers in the evening.

 

Another thing, but this is more about the scene, is when the MC is pilled by stepsis.
I think the "alarm bell" line should be hidden behind some check, I went with a simple intellect check, otherwise the only logical response is to refuse.

This is obviously a subjective thing.

There's a soft knock and the door pushes open before you can answer. Alexia leans in with two steaming mugs, all bright-eyed innocence.(nl:2)
"Heyyy, (nickname:'stepsis')! I made coffee. Figured we should, like, actually hang out one of these mornings." She holds one mug out to you, fingers wrapped around it so the handle points your way.(nl:2)
(if:(twist:1,10) <= (get_intellect:))[
  Something about the way she's watching your hand more than your face makes a little alarm bell ring in the back of your head.
]

But a good start, I'm looking forward to where it will go.

I'm also encountering this issue. Do you know if this mod has any conflicts, or needs to be in a specific spot in the load order?

[david161022]

I have the same issue where it doesn't show up in your inventory. Also, does the continue part of this work? it doesn't seem to.

[Dom17171]

looks like this mod is broken until it gets updated. I'm getting the same issue of it not appearing in my inventory after purchase, on top of getting the same error as kcol when trying to purchase it
