Creator notes

You've been inflicted with an arcane curse that leaves you no choice. you must have your body reconfigured and grafted onto another person as their living body part for a year.

meet your "Guardian" Jessica: she's a young girl who lives a life of luxury. she owns a Lingerie studio and is just thrilled about the idea of parading you around and pampering you like a cute puppy.

you have a choice, do you choose to become the pride on her chest? or her secret flower?

IMPORTANT: this is designed to run with it's accompanying lorebook, https://chub.ai/lorebooks/anonymous/becoming-a-part-of-jessica-lorebook-60823a5df9ac

you must manually enable the "Sensory Engine" for the part you choose and disable the other (by default, it's set to breasts)

Functionality: First you'll select what part you want and specs (monstrous H-cups? or lithe A-cups?). the absorption process begins soon after. once you're integrated Jessica will leave the clinic and begin living her life.

This is designed to roleplay autonomously. you can just let Jessica take the lead and she'll pamper and tease you. or you can guide Jessica, the character will interpret any command you give as Jessica having thought of it herself.

while the nature of this roleplay is explicitly NSFW the AI won't introduce other characters to have sex with Jessica proactively. you'll need to setup those scenes yourself.

Local Setup: I have optimized for token efficiency everywhere I can so that it can be run on a locally hosted setup, I've had great results with the "Gemma 4 CRACK" model inside Textgen (with the lorebook extension) with thinking enabled when using the lorebook in a local setup, set the token budget to 2048 with max interrupts to 10

Technical Notes: it was very difficult to make the AI understand how bodypart TF works which required a high token allocation for all the various rules and sensation engines. because of this some other things had to be hard coded like Jessica's name, her home, her lifestyle (the AI would just keep forgetting it). I chose a setting that I think would allow for the most opportunities for different experiences and sensations as possible
