That tongue is so long it's kinda of a turn-off for me. But since transparent clothes is always a plus in my book, I guess it's balanced enough. Besides, those pointy ears are cute as hell.
one special way to get a man is when monstergirls try it to get him over his parents, wife or children it´s also easy for them to fulfill humans dreams like etnernal youth, become rich, active sex life, help to make babies ( manticor/scorpion poison), any clothes that you want (spider threads). maybe if it work gave old people their youth back, ill people their health and save badly hurted people their life when they become a incubus and a monstergirl. to be honest it would be hard to say no for humans to this.
