After buying a lactation-inducing pill on a dare, Hibisato ends up hooked and spends night after night playing with her milky tits 'til sunrise. She tries to quit cold turkey for the sake of her sleep schedule, but the urge hits her at school, and a concerned classmate - who also happens to be her crush - walks in on her during an intimate moment. Will she learn her lesson?
