Kaori raised her late husband's only son, Kenta, overcoming difficult times to build a happy family life. However, Kenta is deeply dependent on his mother, habitually touching her nipples, bathing with her, and clinging to her like a child. Wishing for his true growth, Kaori decides to end his virginity herself—spreading her legs and guiding her son's penis into her. Captured in digimo, this work portrays the deep bond between mother and son, and the emergence of a new, adult relationship, telling a story meant for mature audiences.
