His brother pecks his sister, even tho' she asked him not to.

The horny brother does not shine with beauty and intelligence, and spends most of his time watching porn, to which, incidentally, he jerks off. Well, to try sex with a live girl or woman, he started hitting on his sister. He was so persistent that despite the fact that his sister asked him not to do it, he still stuck his dick in her pussy and fucked her, getting no real pleasure from sex with a live person.
