アルラ・ルーティー

A plant monster of the Alraune species. With a small amount of dryad blood in her, she has taken a unique appearance. She obtains her nourishment through the roots on the plant part of her body. As the roots wrap around a man’s genitals, the stimulation forces them to ejaculate. In this method, many men are sucked completely dry. In addition, if they particularly like their prey, she is known to forcibly assimilate with him. Leaving the man’s will and consciousness in tact, their bodies unify as one. The body is completely under Alra Rooty’s control, and is used as little more than a source of semen. [From In-game Monsterpedia]
