イソギンチャク娘

An aquatic monster that lives on the bottom of the sea. Like the Jellyfish Girl, she uses her tentacles to catch men off of boats and beaches, drawing them to her. Unlike the Jellyfish Girl, she uses her tentacles to hurt and torture her prey to weaken them, instead of pleasuring them. Once weakened, she uses her tentacles to force him to ejaculate continuously so she can feed on his semen.

After humiliating her prey, she will draw him into her. Once inside, she will start to digest him at the same time she squeezes the rest of his semen out. Extremely cruel and almost impossible to escape from once caught. Luckily, they are few in number.
