Beast City follows the adventures of Mina alias "The Vampire Madonna" and her two sisters, who are all "Draculons" (sex-craving vampires who get their energy by sucking blood from stiff cocks.) Their enemies are the Sex Demons, who look like humans but have snake/penis creatures that emerge from their mouths and crotches to fuck their innocent victims.

Sexy highlights include Mina being jumped by her horny vibrator-wielding sisters in the shower and a young girl masturbating in front of the boy she has a crush on in the school library. Kinky highlights include a lady Sex Demon elaborately binding and torturing another young student girl, and the Sex Demon King's throne, which is composed entirely of bound naked girls! Includes in interesting bonus documentary about Japanese animation.
