It is NOT pornography. It is part of Brazislian movie Viciado en Cú (Hooked in annus) 1984. It is a bit complicated memories of a man about strange sex with women, sex with animals, about homosexuality etc. Unfortunatelly this film has never been finallly cut (on financial purposes). Director rejected prornographic version of it and for normal auditorium it was too scandalous movie. This boy David Cardos Jr, is son of the director (he was 12).
