Excellent story! Here is a story idea in the hopes of getting your inspiration up for a sequel.

Months later, Anna is at her best friends place for a sleepover where it is revealed that she's dating Andrew. They have a normal relationship except he likes to tease her about owning her cunt. Somehow a cat knocks over a cup spilling liquid all over Anna and she's forced to removed her shirt, revealing the bra she made from her womb with maybe the fallopian tubes and ovaries acting as the tie. Her friend is completely enamored of the new bra and shyly asks for one of her own. Anna reluctantly complies and using the knowledge she's learning from Andrew (since he's a smart nerd and she can't quite get through life anymore being slutty without a cunt) she harvest's her friends womb. But since Anna's doing all the work, she asks for her friend's cunt as payment, thinking she'd like to make it into a purse. Everyone survives and are happy with their new accessories. Weeks later, another friend spots Anna's new purse and wants one just like it. And in conclusion, Anna begins to dream of becoming the first ever girl leather fashion designer.
