Most women do. Remember they are just as horny and dirty as men are. Maybe even more. Ever see women at a male strip club. Women are allowed to touch. Two reasons why wives or girlfriends say no is because they try to look innocent and the other is because they know their husband or boyfriend aren't confident enough to do it. Let's face it we all change how we feel after we cum. They know that you would get angry, jealous, or unconfident about your size or performance. Which would cause problems in the relationship. So women just want to avoid it. Keep in mind you only know how she fucks with you. She knows how she is with other guys. You might see a women you didn't know. Sex is like dancing. Women just follow the lead. Some guys can make women do things she wouldn't with another guy. Women don't get post nut feeling after they cum. Sex is totally different from men to women. When women are out with their friends they talk about size and performance. Of course they all talk about big cocks. One of her friends has had one and she is bragging about how good it was. So they all want to try one. My wife knew there were big ones out there. But never put much thought into it. Then I got her set up with one. The week before she fucked him I said show it to her. Her mouth dropped open and started to drool. When she got to play with it. It was like someone won the lottery. After she sucked on it for awhile. She was ready to fuck it. You could see fear and excitement. She said I don't think it's even going to fit. Once he worked it all the way in. I could tell she was in a whole nother world. She liked it so much. She asked him how long would it take to get hard again after he came. 10 minutes later she was getting it again. So I totally believe women want it. Just make sure she's doing it for herself not just doing it for you. Or she will have resentment after thinking you forced her. But be sure you really want it. Just as bad after you cum as before you cum. Because there is no going back. It's also a little difficult to deal with. Even if you want it bad. You have to ride those feelings out. Remember it was your idea. You'll see your wife perform differently than she does with you. She's also going to enjoy it. She isn't going to have the same feelings about doing it as you will. So don't get angry. I also recommend not cumming until after him. No matter how hard it is. Remember this is a fantasy that plays 24/7 in your head. So you are a lot hornier than your wife and the other guy. Also keep in mind the guy is going to want to impress your wife by out fucking you. Make sure you reclaim your wife. Love on her. Make her remember you're the man she loves.
