My childhood friend Rie, a beautiful black-haired girl who is popular at school, always treats me like a child and teases me because I'm a virgin. I've finally got a girlfriend, even though I'm not that popular! When I told Rie about it, she made a surprising proposal: "Have you ever kissed someone? If you can't do anything, she'll hate you! I'll be your practice partner until you have sex." I was confused, but I didn't want her to hate me, so I followed her advice... My first kiss and the structure of a girl's body... it was softer and warmer than I imagined. "Be gentle at first... hmm, good at it..." I saw Rie, who was more shy than usual, and for some reason my heart skipped a beat, and before I knew it, I was swinging my hips in a frenzy and climaxing inside her... My first kiss and blowjob, my first time in a uniform, a body-washing titjob, thigh ejaculation in a cheerleader outfit, continuous creampie... a total of 7 ejaculations. A youthful lovey-dovey sex story of losing my virginity to "Rie," who was the closest person to me to my girlfriend.
