Amu-chan, 21 years old, university third-year. The gap between her little-sister-like cuteness and her beautifully proportioned big tits is insane. When she starts a naughty oil massage with her male friend, her slippery, glistening big tits lock eyes in place. At first she laughs it off as "pervert," but as the fingertips crawl over her skin, her breathing grows ragged, and the moment she starts seeing him not as a close friend but as the opposite sex is irresistible. In a private room for two, watch her surrender to desires stronger than friendship—it's a sight to behold.
