[Sanatuki] In/Spectre Erotic Yuki Onna (Kyokou Suiri)

A wealthy collector unveils his sixteenth captured pet — a curvy, big-breasted yuki-onna stripped bare except for her collar, blushing and sweating as guests grope her and pass her around the party. Once a proud spirit with a boyfriend named Masayuki, she's been broken by mind control into an ahegao-faced pet who eagerly services every oversized cock in the room, even oinking a humiliating apology to her lover mid-act. But when the Goddess of Wisdom peeks through the window plotting a rescue, she too ends up kneeling in the training room beside her senpai, discovering that even a goddess can be collared and made into a pet.
