Recently, my married life with my wife has been troubled by a serious issue: I keep losing my erection during sex. Desperate for a solution, I confided in my older brother, who gave me an unexpected suggestion—let him sleep with my wife. At first, I refused, but later we all went out to dinner together. That night, I pretended to pass out drunk while watching my brother make a move on my wife. Seeing her hesitate, then slowly give in to him, filled me with anxiety and confusion—but my cock had never been harder. Overcome by desire, I pulled my wife into my arms, determined to build a new relationship with her, one fueled by this forbidden thrill.
