You won't just be watching. No, if you want to see your wife get fucked, you're going to have to earn it. First you're going to slide her panties to the side and give her a nice long tongue lashing, getting her nice and ready for my cock. Once she's wet enough, you can go and sit in the corner, just like a good little cuck should. I'll pull her panties down, commenting on how nice it is for you to get your wife ready to take my cock. Then I will fuck her in front of you, letting you watch as your wife is fucked better than you could ever manage. You'll get to see every change in her face, every involuntary spasm and hear every groan of pleasure that comes out of your wife. Then, I will cum inside her, of course. After that I will expect a "Thank You" for you, since I did you do you a favor by fucking your wife.
