I received a call from my husband's younger brother, Susumu, after a long time, and he said he was nearby for work and decided to drop by. Since Susumu and I were classmates and have been close friends for years, there's always a special tension between us whenever we meet. Whenever I see him, I can't help but feel aroused and playful—probably because his presence is irresistibly attractive. While chatting together with my husband nearby, I secretly tease Susumu by touching his crotch with my feet, enjoying the thrill. Worried we might get caught, he tries to escape to the bathroom, but I chase after him and start sucking his cock. That day, we managed to avoid getting caught by my husband, and Susumu looked visibly relieved. Sometimes, in the small gaps of everyday life, a little excitement can feel incredibly satisfying.
