鈴木さとみ - 義理の息子は私の大人のおもちゃ - part3

My husband's younger brother came to visit for the first time in a long time because he had business nearby. My husband's younger brother, Susumu, and I have known him for a long time. While the three of us were chatting, I was enjoying the thrill of touching Susumu's crotch with my foot so that my husband would not notice.
