While I'm at it, I should tell you that, contrary to what you might see in videos and read in stories, your Mother will never scream, "Give me your huge cock! Fuck your Mother!" That's just not her, for one thing, and for another, she's your Mother. She's afraid of losing your respect. She's afraid of you thinking she's not the paragon of virtue she wants you to think she is. If you want a re-creation of a porn video, go somewhere else.
She is a strong and dominant woman. She likes being in charge. But in this, she's not going to be in charge at first. You know where you want to go, you have a plan to get there, and you will be in charge. Maybe at some point later she will take charge and, if that happens, you'll have a tiger by the tail. Just hang on and enjoy the ride. For right now, though, you're in control. Are you ready for that?
Tiny steps. To make this successful, you're going to have to commit to a very long process. It could take a year, or years, or forever. The journey is the goal, remember. Believe me, it will be worth it if you commit to the long haul, but don't think you can just grab her ass, let her see you masturbating, and think she's going to jump in bed with you. Just grabbing her and showing her your dick would not be very respectful, after all, would it? It's all going to be incremental, and the increments are going to be taken in small steps. At every point, you will be able to back off or even stop altogether, with no real risk and no real loss, and you'll keep your gain. But because the steps are incremental, you will always see progress and, as you go along, you will see success that you could not have achieved earlier. You will plant a seed, let it grow strong roots, and then plant another seed.
What do I mean about it being incremental? Well, at some point on this journey while I'm asleep in bed and you two are alone, you may find yourself on the couch with her making out like two horny teenagers. You may be thinking that you've reached the point where you can touch her breasts. It's a big step, but you may well be at that point and, if so, good luck. But as you consider, in the moment, whether the two of you are ready for that, consider this. You're on the couch making out with your Mother! If you had tried that six months before, you likely would have gotten slapped in the face. How did you get to this point? Tiny steps.
I should tell you why I think your Mother might be receptive to your attentions. Do you remember that trip we took? Do you remember how we all had to share a hotel room the first night? Your Mother was getting ready for bed and was standing at the sink wearing just panties and her tee shirt. I couldn't keep my eyes off her perfect ass, and I know you couldn't, either, even though you tried to look as if you didn't notice. Later in the trip, when she and I were alone, I told her about how turned on you were by her. She got angry with me. She said, "That's just creepy." While she seemed upset, something in me said she protested too much. Of course, I'm her husband and no matter what happens, she is never going to let me know what might be going on in her mind or between you two. She has to make me think the whole idea is repulsive to her, no matter what the truth is.
I thought about it. She seemed, to me, to be a little interested. Even if she were not ever going to act on it, what mother wouldn't like the idea that her son thought she was beautiful and sexy? I knew what she was thinking because I suggested she allow your desire for her to help the two of you get closer. I said, "Flirt with him. What's the harm?" Again she got angry, responding, "No way I'm going to flirt with him. That's sexual." Now I could be wrong, but I don't think harmless flirting has to be sexual. People flirt all the time and it doesn't lead to sex. But in her mind, thinking of you, she thought, "Sex." But how could I know, for sure?
Then it hit me. Her panties. If she was excited, her panties would show it. If she was not excited, there would be nothing there. The next day I looked in the dirty clothes pile, and your Mom's panties were soaked with her juice. She was turned on. I know your Mother, and I know how much juice she produces based on her level of excitement. I have not been the cause of that much pussy juice for years. But regardless of whether she was really mad or not, the greatest gift I have given you is that I planted in her mind - if she didn't have it before - the idea that you are a man and that you want her as a woman. I planted in her mind the image of you making love to her.
It's not necessarily a negative thing that she got pissed off. After all, I told her that her son wanted to have sex with her. If she had never considered the possibility, of course she might get mad at it. But again, the very fact that she was talking about it, even if she was vehemently denying the possibility, meant that she was considering it. The brain is a funny thing. The more she tries, in her mind, to not think about you in that way, the more she has to think about you in that way. Saying to herself, "I will never do that" means that she has to visualize what "that" is. I can't tell you if, before I brought it up, she had ever thought or fantasized about making love with you. I suspect she had, just because research says that most mothers have had fantasies about their sons. But even if she had never thought it before, I guarantee she has thought about it now. I guarantee it is in her head and I'll bet she thinks about it every day. It's a matter of time until she dreams about it, if she hasn't already.
The last day of the trip, we again had to share a room, and she did the same thing - stood at the sink, in full view, wearing just her panties and tee shirt. It may be a small thing, but I think it's telling. Without being obvious, I watched her. If she were really bothered by the idea of your wanting her in a sexual way, would she not have kept her pants on and taken them off under the covers after the lights were out? But she didn't do that. In fact, she walked around the room several times and even went to your side of the room to get something. At the foot of your bed, she turned around, faced you and made sure you got a full view of her pussy in her panties and her hard nipples in her tee shirt. There was no shyness there. I think she wanted to give you a treat, and I hope you saw the same thing. Maybe the panties she was wearing were no more revealing than a swimming suit, but they were her panties, and that's different. A woman may let people see her in her swimsuit, but she's not going to let just anyone see her in her panties. Even if we take a more innocent explanation that she might view you as not sexual because you're her son, in this case that doesn't wash. She knew better because I told her it seemed obvious to me that you wanted her.
As an added bonus, I will tell you that when she got in bed with me her nipples were as hard as little rocks, and she would not let me touch her pussy. I suspect it was because she was pretty wet. Then she laid on her side facing your bed, and I know what she was hoping to see. I think she was disappointed you did not have an obvious erection when you stripped down to your underwear and got into bed. But I understand. At that point you didn't know what was going on and you didn't want to embarrass yourself in front of her. From here on, you know what is going on, and things will be different.
The next morning, I hoped to check her panties again when you two were out of the room, and couldn't find them. When we got home, I checked all the dirty clothes, and those panties were not there. I had a delicious period in which I thought she had left her soiled panties with you when we dropped you off. "Jeez," I thought. "They may be much farther along than I know." But in the clean clothes after laundry, they appeared. I can only assume she hid them, knowing they were extra juicy and that would be evidence of her excitement for you. I certainly had done nothing to excite her. Maybe I'm making a mountain out of a mole hill, but I think it does mean something. I think she wanted to turn you on.
I'm going to make another point about my suspicion that she hid her panties. You might think, "Wow, he can make a big deal out of nothing." In your journey, you are going to be super alert to her every word, every nuance, and every action. You are going to have to be so tuned to her that a sigh can speak volumes to you. So, in this case, here is my interpretation. I searched both the hotel room and the dirty clothes hamper when we got home, and I could not find those dirty panties. If she did hide them from me, then that is a very good sign for you. She is already starting to be careful that I not know what is going on. She has a secret, and it involves you. That's a major step, and a good one.
So, I do think you have possibilities you can explore. As I think about it, I can remember other times she has seemed to be teasing you, giving you signals. It may have been innocent (ha!), but don't you think it's time your Mom has to put up, or shut up? I can't say it enough, though - go slowly and carefully. Your Mother loves you, and you don't want to do anything to risk hurting her.
