He teaches his sister's whore how a good slut should be

This aunt wants to know how a good slut should be, because she is currently getting very bad results with the boys she goes out with because they tell her she is a close one. The little slut needs to know how to fuck like a real slut and give herself pleasure even because she has never masturbated. Her brother is a crack of sex and is going to help her, so she teaches him to masturbate with a dildo, to suck cock and to fuck behaving like a sow that makes all the uncles want to also put his cock as he is doing.
