Nidoqueen giggles for a bit as she lifts her tail, allowing you to take a closer look at her well-built posterior. After a few seconds, she lowers it, causing you to be pushed through her sphincter.
Inside her ass, it's nowhere near as disgusting as it would seem. It feels like a tight, warm pocket, much like a dryer and tinier stomach. The place starts to shift around you, and you realize that Nidoqueen has started walking, no doubt enjoying the fullness of her rear.
You feel so good in here, and it just makes you want to really enjoy it... but how?
