Used to talk to wife about her fantasy of being forcibly fucked while doing her. She loved that fantasy. Months later I decided to make her fantasy come true. Told her I had to go to Home Depot. Our friend Mike was in on it. So when I left, he was down the block waiting. As I drove by, he went to my house. I waited about 10 minutes and snuck into the front door. I could hear her protesting as he was working her pants off. He told her to turn around to which she responded no. I heard him exerting his power over her. Next came the sound of her moaning as I guessed her being penetrated. She was sounding as she was in euphoria, breathlessly telling him to hurry as I would be home soon. He ignored her, pounding her another good 5 minutes before he began grunting. She was loudly repeating YES, oh YES as I quietly crept out and went to my car down the block. I waited a few minutes then drove into the garage. When I walked in I said, "Mike? What's up? Sorry I wasn't home, I had to go to the store". My wife was slightly red-faced. After making small talk with Mike, he left. She never said anything, but the sex was great and she never said a word. But, I knew.
