ある日偶然、学生時代ゲーム仲間だったまひろと運命的な再会をした。すっかり垢ぬけて可愛くなっていたまひろだが中身は気さくで話しやすいまま。そのまま飲みに行く流れになりSEXの話題で意気投合。自然な流れでホテルに行くと…体の相性がバッチリすぎた!セフレ以上恋人未満。ヤリまくり半同棲生活、スタート。
One day, by chance, he had a fateful reunion with Tamahiro, who was his gaming buddy from his school days. Tamahiro has become more sophisticated and cute, but on the inside he remains friendly and easy to talk to. They started going out for drinks and hit it off over the topic of sex. When we went to the hotel naturally… our bodies were so compatible! More than a sex friend but less than a lover. A half-cohabitation life where we fuck each other begins.
