"So, I'm your first. I'm honored." When I woke up, I found that my boss had made a full transformation and was kissing me down "there"... making me cum over and over again until I passed out. A run-of-the-mill office worker, Tsumugi Yokoyama, was being bullied by her seniors when she was rescued by her boss, Masuda. He gave her a refreshing smile and said, ""It's my privilege as your boss to see you cry."" It is thanks to him that Tsumugi starts to feel full of life again. However, when Tsumugi is involved in an accident, Masuda changes completely. He says to her, "I'm going to love you so much you won't be able to think about anything." She then finds herself drowning in the twisted love of her boss who was kind to her.
