Aoi, a beautiful, cute, and popular girl, is my childhood friend, younger than me. She always teases me because I'm a virgin. However, I finally got a girlfriend! When I told Aoi, she unexpectedly offered, "Have you ever kissed? Should I be your practice partner?" I was surprised by the sudden offer, but I accepted Aoi's proposal, not wanting my girlfriend to dislike me. My first kiss, my first time touching a girl's body... it was soft, warm, and felt better than I imagined. Aoi looked unusually cute today. My childhood friend and I had our first kiss and fellatio, leading to an unexpected deflowering, gently guided by Aoi. Other scenes include a body wash and handjob in the bath, a titjob, footjob in a competitive swimsuit, mutual masturbation, and passionate sex with cumshots and facials, totaling eight climaxes. The person who was truly important was closer than my girlfriend. This is a story of graduating from virginity with my beloved childhood friend, who, though clumsy, sees me more than anyone else.
