Next door to our apartment live my wife and her parents. Her mother, Aki, is very beautiful—not just pretty, but exuding a strangely seductive charm. Because of that, I haven't been intimate with my wife lately. She wants a child, and I assume she thinks I feel the same, but honestly... I'm not so sure. Recently, my father-in-law got injured at work, and his younger brother carried him home. When they brought him back, a potency supplement fell from his pocket. As I heard more from my father-in-law, I learned that Aki had been sexually frustrated, and he'd been forcefully satisfying her needs.
