Erotica Sex Story: My little sister was adopted into our family destroying my privacy as an only child. She was only bratty to me because I am a boy and she teased me in private using her body to disturb my comfort zone. Now I am paying her back for her naughty actions and we seem to have reached an understanding about our covert coupling because we are not really blood relations but simply a boy and a girl in close contact around the clock.
