After missing the last train home to be with my girlfriend who was waiting at home, I went to the house of my colleague Kana Momonogi, who is very lovely and approachable, so I really like her. Here, seeing her in home clothes without any underwear, exposing her pure white round breasts made my heart feel restless and difficult to bear. And then, I couldn't resist the temptation of the girl from work who had been secretly in love with me for a long time, so I ended up doing something wrong to my girlfriend.
