Cassie woke to see Grandad disappearing into the bathroom, the whiteness of his bottom seemed to glow in the dark. The sound of running water aroused her suspicions as she lay waiting for him to return. "I wonder what is taking him so long," she thought. Rising from the bed Cassie wrapped the sheet that had being covering her and made her way to the bathroom. As she opened the door she saw Grandad leaning over the huge bath turning off the taps. "Good morning honey, how would you like to join me in the spa bath, there is more than enough room for both of us." Dropping the sheet Cassie stood in front of her Grandad and said, "That sounds like a wonderful idea. And reaching to wrap her arms around his waist she cuddled into his back and said, "Thankyou for last night Grandad, I certainly liked having your cock in my ass." I'm pleased you were ok with what we did, as I said I have quite a few fantasies and I hope over time we will get to fulfil them together." "I hope so to Grandad" Cassie replied.
Turning to face his granddaughter he gathered her into his arms and hugged her tightly. "Cassie I think you are wonderful letting an old man like me love you like I do." Then he lifted he into the bath and slipped in facing her. His legs spread so she could sit between them. Reaching up he pushed the on button to start the whirlpool. Cassie leaned back to enjoy the feeling of warmth the was encircling her body. Grandad watched her as she lay in the water, her firm lush breasts pointing towards the ceiling. Oh how he loved playing with them, and he knew what he did to her breasts every chance he got pleased her.
As the water bubbled around them Grandad felt the familiar feeling deep in his groin. Just looking at his granddaughter turned him on and now was no exception. Within minutes his cock was sticking straight up and the head of it was protruding out of the water. At that moment Cassie sat forward and saw his erection, lying back she lifted her leg and raised her foot toward it. Caressing his cock with her foot she smiled and asked innocently, "Do you want me to give you a foot job?" You are welcome to do what ever you like Cassie, as I told you yesterday, nothing at all bothers me when it comes to sex." With that Cassie said, Ok Grandad, stand up then. I want that cock of yours down my throat."
Without answering he stood before her and poked his huge twitching erection in her face. Cassie responded by licking the end of his cock and then sucking what she could of it into her warm mouth. The feeling was incredible, so much so Grandad had to hold on to the towel rail beside his to keep his balance. Cassie was doing a fine job sucking on his cock and it wasn't long before he felt the familiar tightening in his scrotum and tingle down the length of his ten inch raging hard on. Wanting to thrust he gently pushed forward to encourage Cassie into taking more of it into her throat. Cassie tried to take more into her mouth but it was far to long so she gently sucked and licked the huge mushroom head till she could taste the saltiness of her granddads precum. As he moaned and signed Cassie sucked harder and harder wanting him to once again cum down her throat as she had done before. Remembering how much he loved her swallowing his cum made her want to please him again.
