I really like your analysis.

I really fucking hope you’re right.

Alcove in blue. It didn’t extend into her intestines or anything, it was just a small pocket in the back wall.

I actually dated a girl who had a chambered pussy. She was born with mild spina bifida, and there was a scar on her tailbone.

Anyhow, she loved doggy style. I’d get going good and then pop the head of my dick into the alcove, she’d cum her brains out.

Fun times.
