今までスポーツ一筋で生きてきた。そんな自分に初めてできた彼女、大学のバレー部の先輩『るるさん』。部活で教えてもらう事も多く気づけば惹かれていて、付き合える事になった。だが自分には悩みがあった。運動一筋で体力があるからか理由はわからないが、所謂絶倫で一人でする時も1回出したぐらいじゃ収まらない。何度か体を重ねる内に彼女にその悩みを打ち明けると、あっさりと受け入れてくれた。「1日10回抜いたらいいんじゃん！」バレー一筋だった彼女も体力お化け、そして自分と同じように強い性欲。今日も、精子が空っぽになるまで1日何度も射精するまでセックスを繰り返す。
I've lived my life solely for sports. My first girlfriend is Ruru, a senior on my university's volleyball team. I learned a lot from her during club activities, and before I knew it, I was attracted to her, and we started dating. But I had a problem. I don't know why, but maybe because I've been so athletic and have so much stamina, I'm what you'd call a sex machine, and even when I masturbate, one ejaculation isn't enough. After we had sex a few times, I confided this problem to her, and she readily accepted it. "Just cum 10 times a day!" She's also a stamina monster, having dedicated her life to volleyball, and she has a strong sex drive just like me. Today, too, we have sex repeatedly throughout the day, until I ejaculate until I'm completely empty of sperm.
