Having drinks with coworkers after work, everyone missed the last train and ended up going to karaoke for a fourth round past 3 a.m. Gradually, all the others fell asleep, and before I knew it, I was alone with Moe Amatsuka. Though crossing the line between coworkers should have been out of the question, those feelings could no longer be suppressed. With a colleague sleeping right beside us and the risk of getting caught, we gave in to our uncontrollable desires. That night, the two of us gave ourselves completely to sex. Holding onto a promise to keep our secret, we spent a night together—just the two of us.
