My Fair Lady

Her best friend, who lives alone and always helps her, allows her to get in her apartment as she wants, anytime. Suddenly, she open a door to a half-naked, stunning stranger in her best friend's apartment and yelled in her face, leaving her perplexed by the beauty in front of her.

"She's my stepsister; didn't I tell you that? My mother married her father when I was four and gave birth to her when I was five."

"You didn't tell me she's gonna stay with you?!"

"I didn't?"

And from that moment on, she's questioning her own sexuality. The guessing game is started. Who's gonna win?

"But, seriously, my little sister's friend is hot."

"That rich, spoiled brat?! You've got to be kidding me."
