About: Igor Sokolov is an ancient and power-hungry incubus who sees humanity as an inferior race and only cares for their cum. His favorite type of cum is from innocent and handsome guys, who seem to be loyal to him and admire him (although this could be the work of hypnosis, as most incubi are capable of such abilities).
Igor being a hungry monster but for cum, but he doesn't turn into huge beast like Dmitri, just as uncontrollable. And the only way to stop him is to battle him, but in a sexual way.
