Turn the world upside-down

"Okay, well... how can I get in?"

Zoe clapped her hands together in excitement. "No worries, I'll make it easy. You're going to have to share space with a slime, but she'll go where she's needed, so just ignore her. But for now..." Zoe climbed up onto the conference table, and you watched as her body slowly split open, arms and legs, torso and face all splitting down the middle.

You held a hand to your face as you watched in detail. It kind of did feel reminiscent of a scene in a horror movie, but everything was calm, nothing was jumping out of--

A green slimy head popped out of Zoe's torso all of a sudden, and you jumped in shock! "Gyah!"

"Oh, sorry. Come on in, it's easy!" Chloe spoke, before her head disappeared again, seeming to line along the sides of the open torso. "Just say when you are in position, and Zoe will close back up."

You cautiously climbed up on the table, feeling the inside of Zoe curiously. She was sort of like an unusual criss-cross musculature, although you knew it was far more complex at the microscopic level. She looked just like the samples you worked on, for adaptive bandages. This texture was precisely like what was meant to come into contact with the body.

You began to carefully lay down in this opened body, positioning yourself such that your arms roughly ran along the legs, and your legs were about where Zoe's arms were, stretching up above her head. "I don't know how this will work, my legs are too long, and my head..."

"Zoe will take care of that. Are you ready?" Chloe asked.

You didn't understand at all how this could possibly work, but you lay facing upward, just as Zoe had been when she opened. "Y...yes."

At that moment, Zoe began to fold up around you. She stretched and moved herself in a way that allowed her to wrap completely around you, her arms stretching up to envelop your legs, and her torso stretching as well to ensure your head was covered--your head was resting right in her hips when she sealed herself up completely around you in a brief instant.

Your eyes blinked. You felt Zoe wrap around you, but you could still see the ceiling. How can this be? You attempted to sit upright, but when you made that attempt... you felt part of you sit up, your head however didn't move. You thought you were propping your upper body up with your arms, but something was wrong. You somehow sprang upright into a fully upright position. You felt as stable as standing on legs, with your arms sort of bending in strange ways, but your field of vision was so low when you were fully upright...

You looked in the reflection of one of the windows in the office and gasped. You were doing a full handstand, but you definitely didn't feel like it! Your head dangled upside-down, but you didn't see anything upside-down... you tried to take a step, and saw one of your hands move instead. Incredibly, Zoe's body was as she described, fully normal--there was no bump where your head inside her was really at, your arms didn't feel too short or your legs too long. But you were certain you could walk around all day on your arms like this, with your whole body fully upside-down while your arms--inside Zoe's legs--dangled in the air.
