Guivre Girl, or Vivi as a companion, is a monster in the second part of Monster Girl Quest: Paradox.
Monsterpedia Entry
“A mutated Youma that wields both holy and dark power. Although she has very strong magical powers, she is just an unusual monster who can use holy powers, and is unable to perform the holy-dark fusion of chaos. She generally resides in the Monster Lord’s Castle and rarely goes outside.
She requires human semen to supply her magical power, and will give pleasure to any man she captures to make him ejaculate many times to feed on them. If she likes a man, she will use her vagina to thoroughly squeeze out his semen. Her vagina has both divine and demonic properties at the same time, and can alternate between giving heavenly pleasure or hellish stimulation. No man raped by her vagina will be able to hold onto their sanity.”
