The warm night air felt good to Chuck as he opened the sliding glass door that lead out to the in ground pool in the back yard. He'd not been able to sleep, so he thought it would be a perfect night for a swim. A good swim would tire him out and then he'd be able to sleep. Not to mention, if he turned the television on, it might wake his wife Nancy or their 20 year old granddaughter, Heather, who had just arrived a few days earlier to spend a couple weeks of the summer with them.
Slipping his towel off, from around his waist, he climbed down the stairs into the pool. The water felt terrific. For a man in his late fifties, Chuck was very fit and could pass for a man in his early 40s. He prided himself on how well he cared for his body. He swam daily, just not usually at night. He was an avid runner. Whenever possible, he went out and played basketball at the local courts with some of the younger fellows. They were all pretty amazed at how well he kept up with them and often surpassed their skills.
Bracing his legs against the side of the pool, he kicked off and began swimming down the length of the pool. As he finished his second lap, his hands reached up and gripped the edge of the pool and he raised his head up. Wiping the water from his face, he was surprised to see his granddaughter Heather walking along the side of the pool in the skimpiest string bikini he had ever seen.
"Hi Granddad" Heather smiled and said as she saw Chuck looking at her. She knew just by the look on Chuck's face that her minimal swimwear had caught his attention. She wasn't surprised really. She enjoyed the attention she garnered from men.
Unlike many of her friends, Heather wasn't skinny by any means. At 5'8, she was voluptuously proportioned. The skimpy bikini top she wore was just a small triangular piece of fabric that covered her nipples leaving the rest of her ample 36 DD breasts exposed. Her hips were wide and her ass shapely and full. Her bikini bottom tied at the hips and just barely covered her curvaceous ass. She had long honey blonde hair and striking green eyes.
Chuck was momentarily stunned as he looked at Heather. Her body was silhouetted by the light from the pool. He'd never seen Heather in any form of swimwear before and it stunned him to see how shapely she was filled out. Although she was his granddaughter she was damn right sexy. "Hello sweetheart" Chuck replied when Heather said hello. "I hope my late night swim didn't wake you."
"Oh no granddad, I had been thinking about a swim all day. It was just too hot out earlier." Heather sat down on the side of the pool, by where Chuck was standing, and eased her self into the water. From the lit pool Heather could see Chuck's muscular frame and the fact that he was in a Speedo. "Don't let me get in your way though granddad. You go ahead and swim."
Acutely aware of what seeing Heather in her bikini had awoken within his swim trunks, he thought it wise to follow her advice. As he took off on another lap his mind was reeling. Heather was a pretty girl and damn her body was hot. But hell, Chuck, what kind of sick pervert gets a hard on looking at his granddaughter, Chuck thought to himself. The more he thought on this, the faster it drove his laps through the pool. He finally stopped for breath when he got back to the edge of the pool.
Heather, who had swam a lap or two her self came up behind Chuck and hugged him from behind. "Boo!" she said as she gripped Chuck around his waist, her hands rubbing across his muscular abs.
Chuck's body tensed in her embrace. "You didn't scare me Heather. I heard you when you were swimming Chuck said with his voice trembling a little. He didn't like the idea of feeling Heather's breasts pressing warm against his back, and her hips against his butt. "But you do need to let me go kiddo." he said.
"Aww Gramps, you're no fun," Heather whispered very closely in his ear. She could feel his body tense up even more with her breath so close to his ear. She knew what she was doing and she liked the idea of being a tease to her grandfather. She found it hot that she was making him uncomfortable. So instead of letting him go, she pushed it a little further and let her hands slide from his abdomen down to his Speedo's and she got a firm grip on his erect cock. "Ooh Granddad, what's this?" she teased.
Chuck's brain was going crazy. What the hell was Heather doing? Why was he having a physical reaction to his 19 year old granddaughter? "Heather!" Chuck said sternly, "This isn't funny, nor is it appropriate. You need to let me go." When Heather eased up and let go of Chuck, he immediately turned to her looking very stunned. "What's gotten into you?" Chuck said.
Heather knew she had taken this too far. "I'm sorry Granddad. I honestly don't know what came over me." Heather apologetically said. With that she walked over to the stairs and climbed out of the pool and walked back into the house.
Chuck remained standing in the pool and watched Heather as she got out of the pool. Even though he was quite stunned at her behavior, he still couldn't help but to admire just how sexy she indeed was in that skimpy little bikini, her ass cheeks sashaying back and forth as she walked. For a moment he let his mind guiltily wonder what she looked like completely out of it. She had the body of a centerfold. Damn you Chuck, he thought. Quit thinking like a dirty old man. For crying out loud, she's your granddaughter. With that thought, Chuck got out of the pool, grabbed his towel, and walked back inside the house.
The next morning when Heather woke up she felt bad for how she'd behaved the previous night. She loved her grandfather and she didn't like the idea of having caused a rift between them. She would try to make it up to him.
When she came downstairs, for breakfast, Chuck was already sitting at the table and her grandmother, Nancy, was pouring herself a cup of coffee. "Good morning sunshine." Nancy cheerily said to Heather.
