Masabakes

From the lore of northern Spain comes the masabakes, an ENERGY VAMPIRE. It keeps a familiar, a species of imp known as a tentirujo, that it sends off nightly to find a sleeping virgin. When it does, the tentirujo rubs the girl's thighs with a piece of mandrake. The next day the girl is over-come with sexual desire and will seek out a man to have intercourse with. The masabakes feeds off the lustful desire that builds up throughout the day in the virgin and then feeds again as her sexual energy is released during intercourse.
