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

This aunt wants to know what a good slut might look like, because she's currently getting very bad results with the boys she's dating, because they say she's close. The little bitch needs to know how to fuck like a real bitch and give herself pleasure even because she never masturbated. Her brother is a crack and will help her, so she teaches her how to masturbate with a dildo, suck cock and behave like a nut that makes all uncles want to also put his dick like he is doing.
