IBW-161 Life Guidance Teacher Obscene Voyeur

Why would a life guidance teacher, who is originally in a position to give advice on children's lifestyles, do such a thing...? Using the rules as a shield, he hunts down healthy girls and finally reaches out to their undeveloped bodies. Their mouths are mostly like that, but there are a lot of people in the world who get excited when they see that kind of thing, so it's hard for girls too.
