Watching my partner engage in intimate encounter in secluded area with another man

I was chilling at my place, basking in the sweet solitude of my home, when my partner decided to pay me a visit. As I was basking in the warmth of the sun, she decided to take off her clothes and flaunt her natural tits and big ass. I was completely engrossed in her, lost in the beauty of her body, when she suddenly decided to seduce another man. I couldn't believe what I was witnessing, as she took him from a blowjob to doggystyle fucking right in front of me. I was left alone, feeling completely betrayed and neglected, as I watched her engage in this intimate encounter with another man. It was a sight to behold, a perfect mix of amateurs and big asses, as she fucked him with wild abandon. But for me, it was a painful reminder of the cheating ways of my partner.
