I won't name them so they don't feel called out, but I want to thank the person who requested a cage size progression system on the last post as it gave me a lightbulb moment as to how to actually make cage shrinkage work.
To give you all a little behind the scenes view: I've been trying to figure out manipulate WW penis size for YEARS now. I say years because I thought I had figured it out, but it's so finnicky that things weren't actually changing the way that I thought they would. Basically Wicked Whims lets you adjust your sims penis size by increments of 10% in either direction, so I assumed behind the scenes I could do that as well. However it seems that the only times it actually sticks is if it's entirely 100% in either direction, so either 100% big, or 100% little. So while gradual shrinkage like I've been wanting doesn't to be possible, permanent shrinkage is. Introducing the concept of cage sizes, which are usually much bigger jumps in size.
Unlocked Chastity lovers can now choose a starting cage size between "Large," "Small" and "Flat." Each cage size will correspond to your sims WW penis size when they are locked. When they lock their cock, they will begin progressively moving towards flat (this is done using a hidden motive called cage size progression.) When they are unlocked that progress decays, and the cage size no longer enforces WW penis size. However, reaching maximum cage size progression will give the sim a hidden "Permanent Shrinkage" trait which locks them into the small WW penis size whether locked or unlocked. This takes cumulatively about the same time to reach Long Term Chastity, however unlock Lock Time, this doesn't fully reset upon locking.
Cage Size does not conflict with the new Penis Size traits from the new Gay Archetypes update (available Now for the $15 tier). When locked- the cage size traits are in control, and when they are unlocked, Gay Archetypes takes the reigns. However when a sim reaches permanent shrinkage, the Big Dick Trait from Gay Archetypes gets removed, and the little dick trait gets added.
As a sims lock time increases, so does the size of their testicles, to represent the built up arousal from being locked.
All of these changes requires the WW Penis size system to be turned on.
One last note on Wicked Whims- the latest update that added compatibility with Fairies was a bit of a doozy for this mod. Not in that the mod is now broken, but that it added things that could potentially deeply complicate the custom cage system that I just added. Basically the way the mod works is that hard and soft penises are saved on the sim as a commodity (hidden motive) with the value locked as a certain number. When you set a part as either the locked or unlocked the mod basically saves those numbers to seperate commodities that I have created. Prior to this update, there was only two commodties to worry about- a hard penis number and a soft penis number. After this update there are now commodities for every single occult form. meaning vampires can now have two seperate hard AND soft penises, as can werewolves, fairies, and even Succubi from wicked perversions. However each occult are their own seperate commodities, meaning there's now as many as 10 different commodities my mod may have to account for. I genuinely don't know how or if I'm going to take that into account going forward, but it does mean that being locked only effects/is effected by sims in their human form. I haven't tested this yet, but I believe that if you don't choose seperate parts for occult forms this should still be the case but again, haven't tested it so I could be wrong.
Feel free to let me know how important it is for ya'll to be able to maintain chastity between occult forms. I'm a big occult gamer myself but I haven't actually combined occult and chastity gameplay to this extent in a while.
