Bondage And Pleasure

Far beneath the prestigious violin school, St. Cecilia Academy, lies an evil secret.
A monstrous colon-slurping demon lives underground, granting power
to the one who plays the demon violin, Kannone, in exchange for
copious amounts of its favorite meal. To fulfill his half of the bargain, the headmaster begins
an ambitious program to enlist only the most beautiful women into his special classes.
