When you poke something like your finger into someone's belly button, How far does it go in? The most obvious factors is how deep her belly button is, and how soft it is. If someone has a deep belly button, it will allow you finger to go pretty far in before touching the bottom. If she has a soft belly button, you will be able to push your finger further even if you're already touching the bottom, because being soft allows her belly button to be pushed inwards.
This topic is a place to post pictures/gifs/videos where something is being inserted VERY FAR into someone's belly button, whether it's because she has a deep belly button, soft belly button, or both.
For Example:
**
The person in these gifs has both a soft and a deep innie, which allows almost an entire finger to be pushed in.
