Kii

Kii is a parasitic monster girl that mimics the appearance of a petite, loli-like being with a small body, an enlarged belly, and no visible secondary sexual traits. Though childlike in shape, she is an ancient creature that survives by feeding on semen, which serves as her substitute for blood.

During feeding, Kii climbs onto the host’s penis and envelops it into her pseudo-vagina. She remains motionless while strong, milking contractions extract semen. The absorbed fluids cause blood in her body to redirect into her reproductive organs, inducing a deep, trance-like relaxation.

If she is regularly fed, the excess semen accumulates in her chest, gradually swelling her breasts to exaggerated proportions. Once they surpass the size of her head, they act as wombs that birth small offspring, one at a time. These young are sustained by the same fluid that Kii absorbs during feeding.
