JUY-088 My slutty sister-in-law

Having a few days off, the younger couple decided to take this time to visit Shiraki and his sister with the aim of not only helping their relationship become closer, but also wanting to have a truly memorable memory at their home. This. Yes, this is probably an unforgettable memory for them, especially the younger brother's husband. Because my brother-in-law is old and has very limited sexual relations, every time his sister-in-law has a need, he cannot satisfy it, which causes her pent-up desire to become extremely strong. There is a small trigger for it to explode violently, unfortunately that trigger is the younger sister's husband. After accidentally catching sight of her younger brother and his wife having sex, her arousal appeared, followed by lustful intentions arising in her mind. Until the next day, her plan was carried out in a very secretive way. She secretly put sleeping pills in her younger brother's dinner, then when both husband and wife were fast asleep, she sneaked into the room and started eating. expressing her long-standing desires to him, even when he woke up, he couldn't make her stop. After that time, feelings gradually appeared between the two of them. Every time an urge appeared, the sister-in-law would go to her younger brother to satisfy her, and of course he was also very enthusiastic about this.
