Grannies Seduction taken up a notch

I could hardly wait to get to grannies house, She told me she had a bigger surprise then I could have imagined. I arrived at her house on time, I knocked at the door and was invited in. Granny had a trey of afternoon tea. Grandma was wearing a mu mu, as she had before, I thought I wonder what she had in mind? Grany said have some tea? Yes please. Granny said, I have a couple of questions for you, just to be sure we are on the same page. Ok gran, ask away. We have engaged in the ultimate fantasy, for a young man like yourself, wouldn’t you say? Oh yes Gran. Good! Do you still masturbate when your alone? Yes Gran You know I do, why do you ask? All in good time Harris. Do you still Fantasize about your Mother? I fantasize about you Gran. I know dear, but do you still fantasize about your mum? Yes Gran I do. Good I thought so. Anyway lets have some more tea? Yes Gran. We had some more tea and during it, gran remover her Mu Mu, to reveal her dressed in a complete set of pink Lingerie, satin and see through nylon front bra and panties, with white laced edge and pink sheer nylon stockings and Garter belt. I got an instant hard on and said Oh Gran you are so sexy. She said thank you darling. I have a big surprise, I have to prepare you for it, you have to be blindfolded? OK, like a birthday Surprise? Oh much bigger, but yes. I have a very close friend in my bedroom, on all fours on my bed and I promised her a solid fucking, from a young man. Gran put the blind fold on and led me into the bedroom and instructed me into position behind the mystery woman, who was waiting for me. I got into position and pulled down her already soaked panties, felt my way to the prize, and drove my, now throbbing cock, all the way in, with little resistance, as she was so wet, I pumped her with as much force as I could muster, She yelped at first but, started pushing back in time with the rhythm, I grabbed a hold of her hypes and started to speed up, as I was really enjoying it, I love that sound of my balls slapping her ass, I moved my hands down her back and felt she was wearing a bra, so I garbed the bra, with both hands and used it to pull her back to meet my forward thrusts, banging her even harder and faster. Gran was in the room and was cheering me on, she must have been masturbating as she watched, because I could hear her making a slapping sound, like she was using a rubber dildo. I decided to undo he bra, which dropped away easily, releasing her tits, which were bigger than double D, at least. I grabbed them and groped and squeezed them, then I swung on them with the rhythm
