PPPE-183 I've been sucking my sister's breasts for 10 years since my mother's death. You have helped me grow up to be this strong person. Karen Yuzuriha

``It'' started with my mom's sudden death. For the next 10 years, the younger brother, who was unable to wean, grew up using his older sister's breasts as a pacifier. My younger brother's tongue movement when sucking has improved year by year. My sister has become more sensitive year by year, and her nipples, mammary glands, and milk line have become aroused as erogenous zones. Although they are aware that their daily lives are abnormal, the older sister who has a ``bug motherhood'' and the younger brother who has ``crazy growth'' try to break off their distorted relationship.
