Stood there waiting. I was afraid and excited, both at the same time. What if I'd guessed wrong? It was possible that I was kidding myself here. Was t...his like an ant trying to rape an elephant? Every second that I waited seemed so much longer than that to me. By the time that I'd begun to be convinced that I had been right, and the voice would have to deal with me on a more equal footing, I started sensing that I was all alone again. I couldn't feel his presence with me at all. Silence. She stopped, telling me she didn't want it to end yet. We lay down and hugged for a while. We remained gentle, held back by some subtle, self imposed constraint that would not let us take anything too far too quickly.It soon became apparent that the pre-cum at my tip was thicker and slicker than ever before, matched by the surprising size and heft of my erection. Martha Jane grinned as she gave it a squeeze and saw another bead of liquid appear, and she whispered, "Speedy, you get so big now.. It was a nice evening, so people had their windows down, and their music blasting.I could see them as they passed looking over at you, noticing how your dress was tight on your boobs showing cleavage and making them look even bigger than they are.I smirked and mentioned it to you. You could see you were embarrassed, but you started shifting your weight from side to side. I knew as embarrassed as you were, the attention was making your pussy start to tingle and get wet. This guy at the red light. By now it was clear she had never been fucked in the ass by a cock as big as mine.It took about ten minutes to get her loose enough to fuck her, but once she was ready she made the most of it. Once I’d fucked her enough that it didn’t hurt anymore, we moved into the living room and I laid on the floor on my back. Kris squatted above me, facing my feet, and put my cock back in her ass. She sat all the way down and leaned back until she was horizontal with her back on my chest, grinding her hips.
