マッドゴーレム娘

An artificial monster created by magic science with no will of its own. It appears to assist mainly with engineering projects inside Grangold Castle. Using semen for energy, this artificial monster will return to a simple puddle of mud when it runs out. Resupplying is performed by wrapping a male’s body in her mud, and stimulating him until his orgasm. As the man is never killed in process, energy is resupplied to the Mud Golems on a volunteer basis. A while ago an error was discovered in her thought circuit that caused her to go berserk, squeezing random men’s semen to the brink of death. However she was redesigned, and a similar incident hasn’t happened since. But the repairs to her thought circuit seemed to have left her vulnerable to large spikes of magical energy.
