Returning home from work early, I find our neighbor, an old friend, comfortably seated in our living room. But it's the sight of my wife, naked and bent over the couch, that makes my blood boil. He's already balls deep in her, pounding her mercilessly as she moans, encouraging him to 'fuck her harder.' I stand there, speechless, as he grips her hips and rams into her, his thick cock stretching her tight cunt. She cums loudly, her body convulsing, before he pulls out and cums all over her back, marking his territory.
