Character: leech (kostos art)
Leech is a creature created by Kostos. She is a genetically altered Leech who now sports a humanoid physique. Because her leech characteristics remain prevalent, she is near featureless, sporting mostly a shiny black body and puckery green lips as her one facial detail.
Her genetic engineering was for the purpose of giving oral sex (specifically to male genitalia), as her lips prove to be powerful at sucking. However she is sometimes shown to be dangerous in this regard as, being a leech, she might begin sucking more than was intended by the penetrating partner
