飲み会後、終電がなくなりボクの自宅に親友の彼女を泊めてあげることに。互いに酔っていることもありなんかエッチなムードに。親友には申し訳ないと思いつつも寝取る形に…。するとボク以上に親友の彼女は、ボクとの体の相性が良かったのか、朝までヤリまくり！人の物ってより興奮しますよねw

After a drinking party, the last train was gone, so I let my best friend's girlfriend stay at my place. We were both drunk, and the mood became a little naughty. I felt bad for my best friend, but I ended up sleeping with her… And it turned out that my best friend's girlfriend was even more compatible with me than I was, because we had sex all night long! It's more exciting when someone else has you, right?
