Jen figited as she sat on the bus next to Aubrey. She was cold and naked from wearing nothing but panties but no one had even batted an eye at her. But as Jen figited she felt something strange going on. Her stomach was gurgling and she felt it, it was an extremely strange feeling as Jen pressed her hands to her belly.
What she didn't know was that while she would appear mostly human on the outside, internally she was indeed little more than Aubrey's sex system with a dash of waste disposal. Inside her body her stomach was merging with her own womb to create an even bigger womb. Acid bubbled away as her intestines and treat disconnected with her stomach, which connected itself to her old womb before they merged together to create that massive baby maker.
And with the loss of her stomach Jen's intestines were the next to go. They shrunk and shrunk into nothing as empty space took their place, cavities within her body that once served a purpose that she would no longer need as inside her panties her asshole started to shrink.
And Jen felt it quickly shoving her fingers into her panties and feeling with horror as her asshole sealed shut for good. Jen was mentally panicking as Aubrey paid her no attention before Jen suddenly groaned and clutched her stomach. All her previously essential organs were shrinking and sqriuming in her body before slowly fading away as Jen's body started to slowly shut down. This would have ended her if a tube suddenly didn't snake it's way out of where Jen's spine ended on her tail bone.
Jen felt the urge to turn her back towards Aubrey as the tube shot and connected itself to where Uabrey's pussy should have been Sioux anyone even noticing as nuteriets and blood from Aubrey flowed through the tube, saving Jen as she sighed in relief. This was literally killing her, and it was scary, and she really didn't want to see what would happen at school.
