It was a Impulse purchase

Marcus was 92-year-old billionaire, going on 93, and he was in perfect health but, but something happen to change that. What cause it, it was still unknown. He needed a new health body. And quickly Marcus needed a health young male body. With luck 92-year-old Marcus. Will wake up in a young health 30-something male body.

But fate and time couldn't or wouldn't allow it.
He woke up. feeling great, and wonderful, but his body felt different, and odd even. Even he was told that his young body wasn't of a male. It was a body of young early 20-something woman.
Marcus complained, argued, yelled. And that was the first week. The reason why, was his young male body. Was nearly ready. A young women's body was, and he couldn't survive much, much longer. So, they had no choice, but to transfer his essence, to his new body. And it would take time for Marcus adjust into his new body. But after a week later, he slowly adjusted into his new feminine body.
Marcus was adjusting to being a girl, a young woman. At first, he refused to wear anything to feminine like skirts, and dresses. Or frilly blouse or wearing high heels. Or wearing any makeup. Then, Marcus slowly adopted, to more, and more girly, Marcus even started to wear more girly style clothes, like skirts, and dresses.
After the fourth week, Marcus desire, his wants, his needs. For sex, his need to have a guy. Any guy, so Marcus ordered gigolo, for a day of carnal pleasure.
At first Marcus need to release his sexually tension. Until he could be ready to transfer in his male in a few months.
The things the gigolo did to him/her in a sexual way. It was freakily wonderful. No amazing, fantastic. That one day, that one time as a girl. Changed his/her life. Marcus stopped thinking herself as a guy. And she started think herself as a girl. Marcus needed to think of a new name. Marca or Marcia, maybe next or so. I can think of my new feminine name.
