the billionaire's escort girlfriend

She was one of the best at what she did. An escort for prominent and wealthy men. A fake girlfriend; if one may say.
.................
After the dissapearance of her sister, Jennifer decided to take the place of her sibling in the escort agency, thus funding her education and equally luxurious lifestyle.

One client is all it takes to turn the narrative around.

Adrian Brooke was a billionaire. An entirely wealthy succesfull man in the business world. Tired of listening to the complains of his dad about his non-existent love life, he decided to hire an escort as his fake girlfriend for his fathers 64th birthday.

And oh...What are the odds that the escort he got was Jenniffer?
