Going... to... cum... soooooooon... so... sooooooon." I was very close and the delicious friction was making me want to get off soon too, but I wanted...something more. I wrapped my arms around her from behind and without separating us, I knelt to the floor. "Oh Jesus... Jamie... what... are... you... doing," she panted. "Get on you hands and knees my dear mother and spread your beautiful legs wide." I was still buried to the hilt in her tight love channel. I was now kneeling behind her with her. This time, with the other hand I was feeling her naked back and let my hands wander along the small of her back. I wanted to get as much as I could of her now. I could feel the soft curve of her thighs, and drew a line along the bone of her hips, around the side of her. This could be the last time we ever did anything so I did not want to let the opportunity go.She made no mention of my hand lying on her bare bottom and I began to trace a line along the crack of her ass and up under her. Then, suddenly, the dog rose up on his hindquarters and wrapped his front paws around her shoulders. The heavy weight of the dog caused her to quiver with excitement because she could easily imagine what she must had looked like to the onlookers with her official Girl Scout panties down around her ankles and her absolutely naked stark white ass cheeks trembling in fear of the huge doggie dong behind her.It was the first time she had ever even though of the possibility that a dog could mate with. Without waiting for a response she pushed her hand inside my pyjamas fishing out my cock, and immediately she began stroking it to its maximum hardness.I noticed that she licked her lips several times as she stroked my hardening cock, I felt a sense that she wanted to more than just stroke it, so I gently placed my hand behind her head and gave it a little shove and soon her open mouth engulfed my penis. Helen's tongue worked its magic on the underside of my cock head as her lips suctioned.
