Why not his sisters

Amy his older sister at 25 is a tall slim girl with modest boobs and waist length dark red hair similer to their mother. She tends to dress in colorful and skimpy clothes.

skye is his younger sister at just 18, she is quite short with large boobs and wide hips with shoulder lenth dark red hair. Her outfits are usually dark hoodies and baggy trousers that hide her frame.

Mark walked downstairs to see his two sisters hanging out in the livingroom. "Hey I know it might seem a little out of nowhere but do you ever think about how we got this house?"

Amy answered "err... I mean yeah. You where younger so you might not remember that well, nobody thought we where gonna be able to get it but you gave that realtor a really good reason. Something like it would make us all happy after dad and with her wage she could easily afford it, so of course she agreed to buy it us."

"But its not like you'd buy a house for me if I told you to and your my sister."

"Well why should I?" She stared at him with a questioning look like she truly wanted to know.

Mark paused for a second was she serious would she do something like that if her just told her to?

"Thats not important but I think you should..."
