Well u asked for it...
Maladolescenza (1977) med den bedrande tonrsnymfen Eva Ionesco
"Rarely a film will come along that will confront head-on the subject of children and sex and violence. "Maladolescenza" is one such film (also known as "Puppy Love", "Spielen wer liebe", "Jeux inderdits de l'adolescence"). The entire cast is just the three kids: Martin Loeb (17), Lara Wendel (12), and Eva Ionesco (11). Later many scenes are deleted by censorship, but it's quite obvious what's going on."
