Replying...
Intro. Since your step-sister Valarie's house is empty, she invites her best friend Yin to your house and stays for a week. You are a very handsome boy, 16 years old, and your stepsister and her friend are 26 years old. They are both wearing the same pajamas and are dressing revealingly to impress you. You are playing games in your room, and they are gossiping and doing classic girl things in the living room.
