"Hi sweetheart, nice to hear from you." Jim said on hearing his daughter's voice. He smiled as he looked at the framed photo of two smiling females. Both blond and very similar features. Jim's daughter Sandy was very young looking for her forty years, and his granddaughter Jane looked far younger than her eighteen years.
"Dad I have a problem. The landlord has given me notice to quit, and we need a place to stay while we hunt around...I was wondering.
"Not a problem sweetheart, be glad of the company, been quite since your mum passed.
Jim's wife Ann had succumbed to cancer two years before.
Jim spent the next two weeks clearing out the two unused bedrooms and fitting new furniture.
"Thanks Gramps, you're the best," Jane said throwing her arms around her grandfather and planting a kiss on his cheek.
Jim gave his granddaughter's waist a squeeze, but the male in him felt a warm feeling in his groin as her young tits pressed against him.
During the next couple of weeks Jim was careful to be dressed moving around the house and ensuring he put on a robe when going to the bathroom in the middle of the night.
It was just such a night when he passed Jane's bedroom to reach the bathroom when he heard a soft moan coming through the slightly open door and couldn't resit a peek.
The sight he saw had his cock spring to attention instantly.
Jane was laying naked on the bed, legs spread and eyes closed. Her fingers on her left hand stroked her clit while the ones on her right slid in and out of her swollen cunt.
Jim was rooted to the spot and his hand instinctively slid under his robe and slowly stroked his rock hard cock. so engrossed in his voyeuristic adventure he didn't hear Sandy silently creep up behind him.
"She's gorgeous isn't she," Sandy whispered in her father's ear. "I love to watch her, and I can see you do." She giggled as she reached for his cock.
The surreal situation completely overwhelmed Jim. Not only was he watching his granddaughter masturbate he was being masturbated by his daughter.
Almost automatically his hand moved behind him and closed over Sandys cunt, he could feel her moist on his fingers as they sli easily into the warm wet gash.
Suddenly reality struck home and Jim pulled his fingers from his daughter's cunt. "God I'm sorry sweetheart!" He whispered.
"It's okay dad, please it's okay really," Sandy whispered and taking his hamd moved it back onto her cunt. "I need it as much as you do."
