The main character of this story is Yuki Morinaga. She has another name she is proud of, "Morinaga Yuki", and calls herself that. The "C" stands for coffee milk. She is a big fan of coffee milk. Just because her name is Yuki Morinaga doesn't mean she only drinks Morinaga and Yuki's. She drinks Akira's too. Her refrigerator at home is half filled with coffee milk, and she drinks it every morning, afternoon, and after a bath. To understand why she is so obsessed with coffee milk, we must first talk about her encounter with coffee. When she was a child, she saw her father drinking coffee (black) with relish, so she tried it secretly when her parents weren't looking, but it didn't seem to suit her taste, and she thought, "This is the devil's drink!!" Since then, Yuki believed that adults who drink coffee, including her father, were minions of the devil, and strongly refused to become an adult. One day when she was in junior high school, her disgust for her body approaching adulthood reached a peak, and she ran out of the house. Running aimlessly, she arrived at a small privately owned store selling snacks, rice balls, bread, and other light meals. She ran out without a wallet, and the owner, an elderly man, offered her a drink: coffee milk. When she heard the name, she initially refused, but the man didn't seem like a bad person, so she finally opened the drink and took a sip. She was so moved that she cried. This was the exact opposite of the devil's drink, an angel's drink. Coffee, which she had previously despised as the devil's drink, could be made so sweet and mellow with the power of milk and sugar...! Yuki returned home and cried to her father. "I'm sorry, I'm sorry...!" she repeated over and over, and her father just hugged her gently. It was as if the milk that was her father was gently wrapping around her heart, which was stained black like coffee, and transforming it into coffee milk.... Now, she is a respectable temporary worker. She lives strong today with the heart of coffee milk, which has both the sharpness of coffee and the gentleness of milk. The highlights are her smooth, shaved pussy and her stubborn refusal to get naked, which tickles the sadistic side of the characters. Why not try making this "Morina C. Yuki" even more delicious with your milk tonight?
