Penelope questioning her lineage

In an expensive penthouse in a building in the middle of Lonest City, 

A young woman had just stepped inside the room that belonged to her brother, she peered around the silent room and patted her bosom when she saw that her brother was still busy with socializing and hadn't returned.

"Oh, thank goodness, I thought I would not be able to sneak out," Penelope muttered as she headed out of the room that was connected to the living room while her brother's room was right across her room.

 She was dressed in a mini black dress that hardly reached past her upper thighs with killer heels.

Her long blonde hair was curled and tossed behind her back, while her green eyes held a lustful look in them. Which only became even more prominent as she had brushed a smoky makeup on her eyes.
