She was feeling restless to have a big cock in her ass, but due to her pain of constipation she kept silent and motioned me to stop and wait for some time. I kept all of my cock in her ass and kept standing still for some minutes. But the heat of her ass was becoming unbearable for me and involuntarily I started giving in and out strokes with my cock. She kept silent and I increased my speed.

Now my cock was moving in and out of her ass with full speed. She held the pillow in both her hands and had put her head on it, to keep the balance and also to hid her face. I was withdrawing my cock almost completely out till only the tip was in and then was shoving it in all the way inside, full speed. My orgasm was nearing up and it involuntarily increased my speed. My mom's full body was shaking with my thrusts and she was wiggling.
