My brother-in-law, who lives with his older brother and his wife, stared blankly at his energetic wife, Iroha, from the morning. Iroha was busy preparing breakfast and getting ready for her brother before he left for work. While cleaning up, Iroha told my brother-in-law that she didn't remember how she got to the bedroom yesterday. My brother-in-law was relieved, but he couldn't help but worry about his wife's drinking habits. Yes, it was yesterday, when Iroha had come home after drinking at a dinner party with some housewife friends. My brother-in-law calmed down the drunk and violent Iroha and carried her to the bedroom. Up until this point, it would have been fine, but Iroha had pushed him down, kissed him, fondled him, teased him, relentlessly teased him, and made him ejaculate. He doesn't remember it. After that, he observed his sister-in-law, and it seemed that her erotic switch was turned on when she was drunk, and she frequently teased him. However, she couldn't tell her brother about this... One day, while her brother was away on a business trip, her brother's wife cooked a meal for a senior colleague at her part-time job who had been very kind to her. They were having a great time, but she felt a sense of crisis when she noticed that Iroha was quite drunk. The senior colleague started to praise Iroha, and Iroha, delighted, gulped down her glass. Feelings of guilt towards her brother, her inadequacy at not being able to stop her, and resignation to her sister-in-law, who had been turned on, all ran through her head.
