Linda's rescue

Confronting Mistyra
After returning to the Science Lab Tower, Lust Doll would learn what Linda never made it back, and the infestation never dissipated. The only option that remains is to return to the Deserted Base and confront Mistyra about this.

When pressed, Mistyra reveals what Linda was taken to the lower levels of the base, where the infestation is much worse than towards the surface. She agrees to take Lust Doll there, if they are willing to risk. But they are gonna squeeze through a small meat... tunnel, which wouldn't be easy. This is the last time to reconsider: once started, there's no going back until the task is completed.

The meat realm
The quest proper starts once you squeeze through the tunnel. It requires either passing Nimble check, indulge yourself (and the live walls), or ask Mistyra, with subsequent scene(s) (and the lust you would end up with) depending on the options picked. Regardless of the picked options, you're gonna be slimed.

However, once they squeeze through, lust Doll would learn what Mistyra has took their clothes, and is not gonna give it back!

This is as far as you can go in the current public version.
