#### *Muramata-San Affection* *I started dating my boss, Muramata-san, who is loved by everyone, but every day I worried that I wasn't a good enough match for her. So I decided to take away a "first time" of her. I carefully familiarized myself with her every time I saw her, and loosened her up. I wonder if this will make my anxiety go away.......* The kind-spirited Muramata holds a secret that no one at her workplace knows. Following yet another mistake made by her subordinate Kaji, the two head off from work to spend a stress-free night out drinking.

Niwa won a prize in another design competition, and the individuality in her works always shine through. By comparison, her senior coworker Motoki's work is just way too normal — that's what everyone else in the drinking party were all pointing out. In spite of that, Niwa didn't criticize Motoki, and she was the only one who didn't. When she ordered another highball, he happened to see that she had some underarm hair. Later, the two of them (almost) bump into each other by the restroom, and she finds herself giving him a better look at the newly grown hair on her armpits. They end up hiding in one of the restrooms, she gets a hold of his dick, and then they have their fill of secret carnal pleasure.
