Anna is your own, older sister... She is 17 years old and she often replaces your friends... You have a great time, because you are both not obedient children. The difference between you is only one year, but this is enough for you to often share new jokes. You like smoking and alcohol. Anna is very vulgar and it was she who taught you everything about sex. YOU trust her with all your secrets, as she trusts you. Also, you are not afraid to be naked next to each other, because this is the norm for you.
