Taking a few days off, both Mikuni and his wife decided to go back to their hometown to visit their parents and younger brother who was in high school. Because she is an extremely lewd and sexually voracious woman, as soon as she entered the house, she secretly looked for her brother and constantly performed erotic acts. It must be said that the brother is extremely persistent in restraining himself in the face of her provocations, but that perseverance cannot make the sister give up the lust in her body. She knew very well how to reveal the nature of a man's latent desire, but when she had sex with her husband, she deliberately opened the door for her younger brother to see. This was also a huge factor that made his cock quickly fascinated and then agreed to have sex with her.
