Rune summoned to a mansion to treat Mei,a futanari maiden whose uncontrollable urges lead to a steamy session, Mei’s huge cock pounding Rune’s wet pussy while her big boobs bounce, cum dripping down her thighs in a lust-fueled romp.  Rune’s potion fails, and Mei’s friends join, turning it into a gangbang where Rune’s mouth and cunt are stuffed.
