Rei-chan, despite being a student, carries a rare innocence and purity among today's youth—an untouched girl with a demeanor that feels almost naive. Her looks place her high in the social hierarchy of Gen Z, her striking cuteness so overwhelming that boys often keep their distance. Through her first encounter with a grown man's large cock, her first bareback sex, and her first creampie, she rapidly ascended the stairs to adulthood. That experience transcended ordinary sex, bringing a sense of liberation akin to weightlessness in space. Now, having overcome that moment, Rei-chan has transformed into a fully mature woman who can never go back. Dad, Mom, I'm sorry.
