Men going undercover to spy on girlfriends or wives

[nymphoandrea]

Hi! I'm looking for two old stories. I think they were both from Fictionmania. These are the details as best as I can remember them, but they could be off.

#1. Was about a man about to get married who wanted to spy on his fiance. He accepted an offer from his fiance's lesbian best friend to body swap with her. She ends up betraying him, keeping his body, and getting married.

#2. Was about a man who I think was already married. He suspected his wife of cheating on him. He either wasn't sure or he was sure and wanted proof, so that he could divorce her and leave her penniless. I think the wife was a super model? The man made a deal with some powerful woman, maybe a witch? I can't remember if magic was involved or not. The man was turned into a porn star and betrayed by both the wife and the powerful woman.

Thanks for reading!
