The first time I caught my wife cheating, it was with a coworker of hers, that I'd met many times, and they were in our basement. I came home late on a night that I told her I'd be staying at a friend's place, but I eventually changed my mind and drove home. I could see the basement TV was on and it was way later than she's normally awake, so I walked to the window and looked down. She was on her knees only in a thong and socks, sucking his cock. His hand was on her head, running his fingers through her hair. After a few minutes of that, she took her thong off and got on his lap and started to ride him. He sucked on her small tits while she bounced. She had an orgasm after he stuck a finger in her ass, and moments later he came inside her. I couldn't walk away, and I watched them cuddle and kiss for the next 30 minutes. She was gently fondling him the whole time and he eventually got hard again. At that point he stood up and went to a backpack. I couldn't hear what they were saying, but I could see her giggle and nod yes. Then he pulled out a bottle of lube and laid my wife on the ground. He applied some to his dick and to her asshole. Then, I watched as he fucked my wife in the ass for the next 25 minutes. She had an orgasm about halfway through. After he came in her ass, he went to the bathroom. I watched her lay on the ground and masturbate to an orgasm with his cum in her pussy and ass. I've never been so crushed and horny at the same time. I literally jerked off 5 times while crying in my car that night and didn't sleep a minute.
