Young boy fucks his mother's slut and sister

What a surprise this boy gets when he gets home, because his mother's bitch is expecting him to make an offer he can't refuse. She tells him that she needs him to be able to teach his sister to be a good whore like her. The boy accepts with his eyes closed and in a moment he already has his sister sucking his cock to practice. Then he puts the cock of both prostitutes, but who ends up carrying all the semen in the face and mouth is his sister, which seems to be the first time he likes to run.
