[Akabane Aomori] Hanako is Slit-Mouthed Mary [Penguin Piper]

A timid schoolboy bullied into cleaning the dimly lit women's restroom comes face-to-face with Hanako, a slit-mouthed spirit whose impossibly huge, soft breasts and teasing grin turn fear into breathless submission. After a strange event on his smartphone leaves him afraid to go outside and hiding in bed, she claims her sole male prey in the stalls with a deep, drooling kiss and a slick, bouncing cowgirl ride that leaves him dazed and dripping. Now a towering, big-breasted Hashaku-sama is waiting in the countryside with a sweet hat and a promise of a happy ending, and his ghostly harem is only getting bigger.
