My neighbor had sex with my girlfriend to orgasm - I masturbated

The day had been rough for me, and all I wanted was to unwind with my girlfriend. But as I walked into the house, I saw her on the couch with our neighbor, getting naughty. I couldn't believe it! I was shocked, angry, and aroused all at once. I stormed out, slamming the door behind me, and headed straight to my best friend's place. There, I let my anger and frustration take over, jerking off furiously as I thought about my girlfriend being fucked by our neighbor. I imagined every detail, from the sound of their moans to the sight of my girlfriend getting creampied. It was a wild, kinky session that left me cumming hard, but it didn't solve my problem. I knew I had to confront my girlfriend, and maybe even my neighbor, about their little tryst.
