義理の兄は私がふしだらな女であることを捕まえたので、秘密を守るためにいつでも彼に私を犯させました

I am pretty adventurous with sex and my parents just don't understand. My stepbrother saw me doing something I know they wouldn't approve of so I had to think of a way to keep him quiet. What better way than to fuck him anytime he wants for a while?
