I remember reading a story a coupe years back. The story had a guy buying a pregnant girl halloween costume for a party from a magic shop but it had a spell that the longer he wore it, the more he became the costume. The story had the guy (now pregnant girl) meeting a girl that had also bought a costume from the same shop that had made her beautiful but also made her a lesbian that was attracted to pregnant women. I believe one of the characters was named Jasmine. Any help is greatly appreciated.

I'm also looking for a similar story where a guy finds a belly suit, puts it on and is turned into a real pregnant woman. His best friend helps hide him from his friends/family and ends up marrying him. Can't remember where I found it anymore.
