A documentary depicting the truth of anal virginity loss. Nanami, a refined schoolgirl with a proper demeanor, agrees to experience her first anal fuck on camera, driven by sexual curiosity. Beginning with anal dilation and finger penetration, she progresses through stages of increasing experience, enduring bleeding during anal stretching, until she finally experiences her first anal intercourse with creampie ejaculation, even going on to experience sandwich fucking. This work faithfully captures the real emotions of a girl experiencing anal sex for the first time—her tension, anxiety, and anticipation. A true-to-life recreation presented as six documentary episodes, including the girl's first anal penetration and bare creampie.
