so I remember this one story but I can't find it anywhere its where a brother gets a sex doll and his sister finds it finding out that its a life sized replica of her she scolds him but while he is out and about she goes in and messes with the doll and breaks it (?) and her brother came home early from...somewhere i dont remember...and she imediately strips and lays on his bed naked exactly how the sex doll was before she broke it (?) he doesn't think twice and a sex sesion ensues without him even realizing it was his sister. I don't remember much after that except that at the end the sister buys something she doesn't want her brother to see and we never get to see what it is. I don't know if they were related necicerally but thats still the basic idea of the story if someone could help me please i would be greatful.
