I'm in an office romance, and I'm at the peak of happiness as I secretly discuss our next date with my girlfriend at work. I thought I was hiding it from my girlfriend, but Satsuki, her junior, found out about it and was invited out for drinks by her girlfriend, who had recently broken up with her boyfriend. Satsuki, who was dating a celebrity, was quite cute, and when we decided to have another drink at Satsuki's house, I couldn't resist her temptation and ended up having sex with her.
