Antlion Girl

An insect-like monster that lives mainly in the desert, she creates a cone-shaped nest in the sand to catch unsuspecting travelers in order to feed on their body fluids. Preferring male semen, she will use her massive mandibles to lock the man's waist in place as she sucks everything out. Once her catch is sucked dry, their corpse is left in the desert.

Although her trap is extremely dangerous, her body is very fragile. The only way to escape is to quickly defeat her before you are brought too far in.
