As we continued to jockey around, eventaully we kind of removed the robes from each other leaving us both completely naked. Once again we were standing and facing each other. Mom said she was going to humiliate me by sitting on my face until I gave up and then spank me until I was red. I didn't know what to say so I just said no way as we approached each other again to lock up with my dick pointing the way. As we came together I could see her nipples clearly giving away how excited she was by what was happening. I was able to quickly manuever behind mom and got her in a full nelson with both of us on our feet. I kept brushing against her backside in this position until I ended up walking her up against the back of the couch. Then I bent her over to add more pressure and my dick ended up riding up between the crack of her ass as our bodies pressed together more. Now the frustration was getting to me, as well as her snide comments, so I asked her how she felt with my dick riding her ass. Now I was getting into it more and she told me to shut up. I asked why, couldn't she take it? It was just seconds ago she was telling me I was going to be smothered by her pussy. She said I was still going to be.
I started grinding my dick a little to let her know I was in control when she stomped on my foot with the heel of her foot. That sent a stinging pain through me and made me release the hold on her. She turned around and kneed me in the stomach and pushed me down to the carpet and sat on my stomach, pinning my arms down with her hands. Now, she said, you will truly be mommy's little boy as she started to slide her body up toward my face. Before I knew it her muff was over my chin. I was repulsed and furious at being in this position and started bucking to get free, finally wiggling my way out from underneath her. We came together again on our knees in a mutual bearhug hold and toppled to the carpet again. I finally managed to get the upper position but as soon as I did my dick slipped into her pussy from both of us moving around trying to gain an advantage. I was a little surprised at how tight she was. She was definitely wet though too. When I entered her we both bucked a little, still holding each other in the bearhug grip not sure what to do. We were both sweaty and breathing hard, her tits mashed against my chest as our faces were next to each other, cheek to cheek. I wasn't about to let go and neither was she so I just cinched on the grip tighter and she did the same. Within seconds our lower bodies started moving too as our battle became a fuckfight as well. I figured if I could make her cum she would be useless and I could really humiliate her. I would later learn she was thinking the same thing.
She hadn't had sex in a while and neither did I since there really wasn't any time I could since I was staying at her house, so, it didn't take us long to climax. I was able to hold out a little longer and made her cum first though, leaving her helpless. Then I was able to pin her arms down and slide up, grinding my dick on her face until I came all over it. I wanted to let her know I had won and this is what came to mind. I face fucked her until I came. Then I got up and rubbed it all over her face with the bottom of my foot, telling her she would get worse if she ever challenged me again. Of course, mom was just as pig-headed as me and challenged me the very next day.....
