Once inside Sarah's esophagus, Mary discovered it actually wasn't too bad. Sarah had swallowed her whole as she promised. There was no painful chewing, tearing or crushing. She just slid into a tight, soft warm tube. It reminded her of when she was child and would wiggle headfirst into her sleeping bag. Of course, this was a little different. She could feel the muscles of the esophagus caress her whole body as it slowly moved her along.
There were a few drawbacks. The smell was a little unsettling at first, but she gradually got used to it. And it was very dark, despite the increased visual acuity of her rabbit eyes. But the pleasant feeling of the slimy soft walls pressing against her furry body made up for any discomfort.
This really was heaven to Mary.
Mary had no idea how long she traveled, but it seemed like she was too quickly dropped into Sarah's stomach. At least she assumed it was Sarah's stomach. Mary was not very familiar with the internal anatomy of snakes but she had been squeezed through some kind of sphincter and dropped into a larger chamber. Well, relatively larger. The walls still pressed against her body but she found it easier to move around and maneuver her body. Occasionally the walls vibrated, rumbling and rubbing against her as the muscles twitched and tried to grind her body. The base of the chamber was filled with a thin warm liquid that caused her body to feel tingly. It was not painful just.... odd. And somehow comforting. Mary found herself drifting off to sleep.
The fluid in the chamber shifted, dowsing Mary's head and upper body. Her body was forced to tumble around the organ. It took Mary a while to realize it but Sarah must have been moving. After a short trip, Sarah stopped. The chamber seemed to shift again as Sarah coiled her tail. A pleasant heat seeped into her home and it dawned on Mary that Sarah had moved to a warm spot to rest and digest her. Mary moved around in the stomach, kneading the flesh to make a cozy spot to rest and soon drifted back to sleep, comforted by the tingling liquid and the gentle vibrations of Sarah's rumbling stomach.
