porno photo of granny blowing and riding cock

Billy nervously parked his car in his grandmother's quiet cul-de-sac. He was here for a special purpose; he had been sent an anonymous link to a porno photo of his grandmother, blowing and riding a cock! She was a respectable granny and he had never even heard her swear before. As his imagination bubbled away, Billy felt his cock harden, and as he sat there he began to fantasise. When his grandmother opened the door, Billy was unable to look her in the eye. His cock was still rock hard imagining her in that porno photo, blowing and riding. She asked him everything was alright, but he couldn't bring himself to respond; his cheeks had flushed bright red. "Come in my dear, let's talk in the living room" she said. They sat together in her living room and she asked him for the third time what was wrong. Billy was about to explain when he noticed something strange; his grandmother's gaze had shifted to his crotch, and he noticed her chest was quickly rising and falling. She then whispered something about the photo. It was a magical moment between them, and without saying a word, they both knew what needed to happen. Grandma slowly unbuttoned her blouse and motioned for Billy to come closer. She then started blowing his cock while he looked down at her, stunned by the thought of his own granny riding his dick, just like in the porno photo.
