Mamichan (pseudonym) in a gym uniform, with a small stain visible. Her innocent, pure smile is incredibly adorable, and she appears to be around the age of a girl still carrying a school backpack. Though still immature as a young mother, her underdeveloped chest has unusually developed mammary glands, resulting in long, jellybean-like nipples that are strangely alluring. Engaging in sex with someone other than her dad for the first time, she becomes aroused and enjoys intercourse while leaking breast milk. Her honest, childlike nature amplifies her erotic appeal.
