Unfortunately for you, the Noivern had not noticed you fall. Instead, he had focused on eating the berries that currently filled his purple belly. With a burp and a sigh, the Noivern sat down. Sliding between his butt-cheeks and straight into the anus above you, a foul smell instantly fills your nose. Eventually even your feet are pulled through. With a clench of the Noivern's pucker, your shoes fall off onto the ground. Glancing around at your gravy-smelling prison, you can only hope that you can escape soon as Noivern's rectal muscles begin pushing you around.
The Noivern could feel you inside his butt. He had noticed the feeling when he sat down and he was enjoying every second of it. He rubbed his lower and upper belly in bliss.
You decide to look at your options.
