Kiriko, dressed as a seductive witch, celebrates Halloween alone, but not for long. A 3D visitor, unseen but felt, teases her massive, round ass through her skimpy costume. Kiriko, aroused, plays along, grinding on an invisible cock. The teasing escalates, and Kiriko's ass is soon filled with a thick, hard 3D cock, stretching her tight hole. She moans, enjoying the anal plunge, her big ass bouncing as she's fucked from behind. The unknown trickster gives Kiriko a Halloween treat she won't forget, filling her ass with hot cum.
