Bible Black: La Noche de Walpurgis (2001)

At a harmless looking College, the teachers and staff are practicing a dark religion. By devoting their bodies to perversity, they chant their dark spells and control the lusts of the student body.

Everywhere the students turn, they are drawn to acts of perversion, even in public. Perhaps the school nurse has the answer, as she holds special counseling sessions for the female students.
