The employee Shinoda-chan started to look at the neighbor upstairs since moving to the new apartment because of her sexy, seductive way of dressing and hot body even though she was married. Coincidentally, he accidentally discovered that his colleague was a student in one of her cooking classes. From then on, the opportunity also began to appear when he was invited by him to attend the class together. At first, he thought she was a virtuous, virtuous woman until he gradually got to know her and realized that his discovery was completely wrong. She was incredibly lustful, from the very beginning she had sexual advances, provoking him until the following days were no exception, coming to her house to learn cooking but was treated like a sex toy by her.
