Harakiri (WIP)
I kept coming across pictures of this sort of belly button pushing fetish so decided to give it a try ^_^
I can already see the story for this one – maybe in the kingdom he's from it is considered beautiful to have a ridiculously deep navel, to achieve that they have a special ceremonial sword-like thingie, more like a training tool that looks a bit like a katana with a short pole replacing the blade, which is slightly flexible (like a bow) for a more dramatic effect in case it's used during a public bellydance performance.
The pole has a pointed end to help the belly reach the ideal shape and depth over the time of practice – dancers give their bellies a daily exercise to work toward the perfection of having a deep navel in contrast to the round lower belly.
The practice itself can be even pleasurable to some, thanks to the huge amount of very sensitive nerve endings on the surface of the belly button.
