Oto, a caring girl with dark hair, is my childhood friend. She always teases me about being a virgin. But now I finally have a girlfriend! When I tell her, she makes a surprising suggestion: "Can we kiss? Shall I be your practice partner?" I don't want her to dislike me... Oto encourages me to kiss her for the first time. I'm moved by the softness of a woman's body as I touch it for the first time! For some reason, Oto seems unusually cute today... My first kiss and blowjob leads to an explosive orgasm. I lose my virginity with gentle instruction. Cunnilingus and blowjob training in the bath. Jealousy masturbation, footjob, and handjob. Role-swap creampie sex... and a total of eight ejaculations into my childhood friend's body. The person who truly matters to me is closer to me than my girlfriend... A youthful, lovey-dovey story of losing my virginity with the lovable tsundere Oto.
