Hinatako has become more confident about her small breasts after many shoots, but she still has a complex about her breasts. She is tempted by the man who says, "If you cum inside me, my breasts will get bigger," and she can't refuse and ends up cumming inside him for the first time in her life. After the cum shot, her breasts really do get bigger (they've grown to a B cup!), and Hinatako loses control and starts to hungrily seek cum shots, even at the risk of getting pregnant.
