Kaho, my wife's best friend, suddenly showed up while my wife was away. I was secretly thrilled—her beautiful body had always caught my eye. The moment we were alone, things began to unfold naturally. I kept sneaking glances at her, grinning to myself, basking in this small, forbidden joy. But as if reading my mind, Kaho leaned close and whispered in my ear, "You've been watching, haven't you? Go ahead, touch me." That single sentence shattered my restraint. Her true intention all along had been to seduce her best friend's husband.
