It doesn’t work. I’m still smarter than he is.”I laugher at her and said, “Maybe not, but I sure got a lot of sex from you in the process. Did...’t I?”Then my beautiful granddaughter took me up to my bedroom.I got undressed and Heather just removed her sexy pink panties leaving her cheerleader outfit on and then she climbed up on my hard cock. As we fucked I remembered fucking her grandmother when she was sixteen years old. I remembered fucking her mother when she was sixteen years old too. Then. That birthday was significant to Caz because he had chosen it as the start of his full-scale revenge attack. On that date, the boy, who demanded to be called Cy outside of his grandfather's presence, could voluntarily give a legal sample for DNA testing.With legal proof in hand that he was not Cy's father, Caz would risk the bogus rape charge. With the kind of legal talent that he could afford, he was confident that any attempt to try him would only result in the final proof of the Reverend's. As I pushed her onto her back and moved on top, she continued to hold my rigid member tightly, guiding my ship into her warm, welcoming harbor.Her eyes were searching for something in mine. Love. She thought she had found it as I began slowly moving inside her. Something inside me hoped she was just fooling herself. Something inside me was afraid she wasn’t.It was late afternoon. We had showered and fucked. We had brunched and fucked. We had talked, and then, for good measure, we fucked. Now. I feel the walls of her pussy spasm around my finger as she cums along with me. She collapses on the bed as he rolls me over onto my knees, my still-tingling pussy quickly being filled by his cock. His hands grip my ass tightly with each thrust. I let out a little scream when he smacks my ass hard. Over and over his cock moves in and out of my pussy, making me so wet that I can feel it on my thighs, bringing me back to the brink of orgasm again. Leaning down on my arms, I push my ass higher.
