My husband's younger brother, Susumu, had some business nearby, giving us a chance to meet again after a long time. Susumu was my junior at Planet Plus High School, and we'd always been close. Whenever I saw him, I couldn't help but feel mischievous. While chatting together with my husband present, I secretly used my feet to tease Susumu's crotch, enjoying the thrill of it. When he realized what I was doing, he tried to escape to the bathroom, but I chased after him and sucked his cock passionately. Somehow, we managed to avoid getting caught that day, and Susumu looked visibly relieved afterward.
