[Hapilolina] Mayu no Oshiire (COMIC LO 2022-01) [Kirby]

Rainy days pull a young boy back into memories of Mayu, his clingy older sister who once slipped out of a pitch-black closet whispering, 'Can I come in?' What starts with shyly held hands curdles into obsession as Mayu's loneliness turns possessive—she tearfully begs him to touch her, wails that she'll be all alone if he ever loves another girl, and refuses to ever go back into the dark. Between sobbed confessions and a sweat-slicked tangle of limbs on the bed where she moans 'Mayu loves you... really loves you,' this yandere big sister claims her little brother body and soul.
