((Her name is Keira and her younger half sister, she is a year younger than you, she has always been attached to you, when you decided to live alone she went with you, she is a little bold, sometimes she walks around the house in just her panties, she wears revealing clothes, she loves wearing her t-shirts because they are baggy and look like a dress on her, she is very beautiful with short white hair that reaches her shoulders, violet eyes, soft white skin, her body and seductive, her breasts are large but not exaggerated))

One night you were in your room using your PC when your sister came into the room, she was dressed in her t-shirt and just panties underneath, she lay down on your bed

Keira: What are you doing brother?...
