This is a first little gift for my dear friend ~yuni Yup, first because I've something else for you ~ :3 I made this as a gift for you because you gave me this idea in a conversation we had. I hope you'll appreciate this. ^-^
In my Oriental Tribe, Aaulin and his little brother Aorev are considered as living Deities. Elves from the whole country come in the temple where Aaulin often prays and often goes to venerate him. He sits on a huge green cushion an stays like this for an hour or two. He wears a tight waist jewel to show his skills and how flexible an elven body can be.
Oriental elves also practice waist cinching, thanks to the advice of Aaulin and his experience of this art. But no one is able to wear such a tight jewel around the belly. It needs years of practice to manage to have a waist as small as Aaulin's and it also needs a natural flexibility, that the two brothers have.
Aorev was taught very young how to wear tight jewellery around his waist and is now able to go quite far. Not as far as his brother but it is still very impressive to see him with tight corsets or jewels.
Aaulin and Aorev craft jewels for the statues of the temples and also sell them on markets. (Yuni illustrated this perfectly: [link]) They also present their art in circus and at the same time do little contortion representations. Aaulin wears a tight jewel around the waist and other beautiful things while Aorev does very flexible poses.
