Gwen once again knelt between my legs, still stretched wide apart. She began running her nails up and down my inner thighs and eventually getting to... the shaft. Finally she grabbed it firmly and slowly started sliding it into her mouth. About two thirds of it had disappeared between her lips when her head started coming up again. Over the next couple of minutes she would slowly lower her head and then rise back up, going a little bit further each time, until I could feel her nose touching. Son lies in wait for his mother to step out of the shower. Or for her to take the vibrator out of her secret drawer. And then he walks in, erection long and hard, and the two just do the inevitable.I had no way of knowing this couple's exact story, but that really didn't matter. I had a front-row seat and wasn't complaining.I couldn't hear what they were saying, but they were standing in front of the bed and he was shouting. I thought it was a little strange, all that yelling. She actually. How dare the bitch treat guys as if they were beneath her! He would make her see that men were clearly superior to women! Women like her made life hard for men! Well, this one would never do that again. She would learn that her place in this world was to serve men, or better yet, serve him! Yes, Dale was a male chauvinist pig, and he was proud of that fact!Darcy stared up at her brother. She trembled at what she saw in his eyes, pure anger! She knew that somehow she pushed him over the edge. Reaching down, I collected her vaginal secretions on my fingers and lubed the exposed part of my shaft. Then, with a grunt, I pushed the rest of the way in. God was it tight! And warm. And soft. It felt great! I slowly withdrew about a third of the way out, re-lubed, and shoved in to the hilt again. After repeating this process a few more times, I was able to maintain a steady motion, sawing in an out of her asshole as she whimpered beneath me, resigned to the unexpected ass-fucking being.
