At a company party, the employee had too much to drink and was helped into a hotel by his young boss, Nanami Misaki, who, out of fondness for him, took great care of him. During that time, he woke up and accidentally saw Nanami's breasts exposed in front of him because she wasn't wearing a bra. Embarrassed, Nanami covered her breasts in response to his stare.
However, having seen that and feeling tipsy, how could he resist hugging her tightly...
From that day on, he realized that his boss was actually very promiscuous, so he frequently looked for ways to get intimate with her, even at the office.
