Jun is a childhood friend who loves to take care of others. She's younger than me, but she always teases me for being a virgin. I've finally got a girlfriend, even though I'm still a virgin! When I told Jun about it, she made a surprising suggestion: "If you're bad at sex, your girlfriend will hate you. Would you like to be my sex practice partner?" At first I resisted, but I didn't want her to hate me... so I decided to go along with Jun's suggestion. My first kiss and the first time I touched a girl's breasts... they were softer and warmer than I'd imagined. Moreover, the more I touched her nipples, the more Jun, who always teases me... got a naughtier look on her face! This is so good! A story of a childhood friend's first time losing her virginity, in which Jun Suehiro Jun, with her fair, soft body, looks like a goddess.
