A school trip packed with first-time experiences! Karin, a female student, and male students Takeru and Taichi were just sightseeing ten minutes ago, ordinary teenagers enjoying their youth. Shy at first, they gradually give in to their uncontrollable desires, escalating into bolder and bolder acts. First time friend sex, first time orgy, first time deflowering, first time bareback penetration, first time creampie—each of their virgin experiences intertwine into a hot and intense sexual journey. In a natural progression, the pure colors of youth blend with the hues of adulthood, creating an alluring scene marking the end of innocence.
