Zombie Girl

Magic collected in a human corpse that turns it into an undead monster. Due to the brain rotting away, the Zombie Girl has almost no intellect, and barely any memory of her previous life. Cold and craving warmth, they desperately attack and rape men trying to claim the faint memories of their old bodies. Though they are very slow, their vitality is very high. Once they mount a man, it's not possible to get them off no matter how much you attack them. The strange feeling of her rotting genitals is able to force men to ejaculate.

Since the Zombie Girl will never reclaim what she has lost, she will continue raping the man until he dies. In some rare cases, the magic sustaining the Zombie Girl will flow into the man and turn him into a Zombie. Like that, he will be raped for an eternity.
