What can be the reason for a girl to stick her own brothers dick in her mouth? Money is just a dangerous thing, anyone saying that money cannot buy anything is just wrong, as long if its enough most people will choose the money in stead of their moral values. Nothing wrong with that, you are responsible for you own choises, i guess its ok as long as you can live with yourself afterwards. Of course im not sure if this is real brother/sister love, its whats been told to me.
