Here are the types of organisms we study. These are not in a contact situation with a human female but their organs of penetration are either naturally, or induced by hormonal or electro stimulation, displayed.
This will give the viewer some idea of the intense nature of these contacts, particularly when force by the creature for the human involved. Altho most are rather plain tube-like structures, many are textured and highly ornamented with tendrils, folds, ridges, spines, knobs, warts, etc. It is those we show here.
Each image is accompanied with a description of the organism, its behavior of interest. Also, additional information, pertinent to the particular creature, or the kind of interact that defines the general class of organism they belong too, is given as well.
