ONE SUMMER

Bob and Alice Hall parked their car outside the train station and with their daughter, Laura, they went to look at the arrivals board. As the train pulled in they craned their necks, silently playing a game of who could see him first. Laura won. She sprinted along the platform and leapt onto her brother.

"Jack! Oh my god I've missed you!" she squealed.

Her parents caught up and hugged Jack. They chatted as they walked to the car and drove home.

Jack Hall was twenty four years old. He had been away at university and was now back home for the summer vacation. He had just finished his second year at uni having travelled and worked a bit since leaving high school.

When they arrived home Alice fixed dinner. As they ate Jack asked the question that had been bothering him for a few weeks.

"How's Nan?" he asked.

Nan was his grandmother. A few weeks ago she had suffered a nasty fall while out shopping and had broken several bones. She had been in hospital ever since, but was slowly recovering.

They chatted about Nan and Jack also asked his seventeen year old sister, Laura, about school.

Laura was thrilled to see her big brother. She missed him a lot when he was away, even though she had been dating a boy called Darren for about ten months. She was looking forward to school finishing and spending the long summer with both her boyfriend and her brother.

A week later Laura celebrated her eighteenth birthday. Her parents took her and her brother to a fantastic restaurant to treat her.

A few days later, Bob took his son aside and asked him a massive favor. Bob's father, George, Jack and Laura's grandfather, was struggling a bit at his home with his wife in hospital. George didn't drive and the hospital was in the nearest big town, about twenty miles away. Bob asked Jack if their was any chance if he would mind spending the summer with his grandfather, helping out. A massive favor, and Bob knew he was asking a lot, but Jack agreed. Unfortunately Laura was very upset at not seeing her brother during the summer.

"Why don't you go too?" suggested Alice.

"Could do. Would you mind Jack?"

"It wouldn't bother me. It would be nice to have a bit of company from someone born in the same century as me! But what about Darren?" asked Jack.

"Oh I know but he's got a summer job so I wasn't going to see him much. Besides if he loves me he'll understand. "

So it was agreed that Jack and his little sister would spend the summer with their grandfather, George, who was thrilled to hear the news.

Their grandfather's house was an old cottage perched right by the sea in a deserted part of the country. It was a four bedroom cottage with a small garden that led onto sand dunes and down to the beach. There was a tiny inlet to the right of the house with just an old upturned rowing boat. Their was a village with a bar and a couple of shops about twenty minutes walk away. But the nearest town was twenty miles away and the buses were not very frequent, so George was having great difficulty doing the shopping and visiting his sick wife in hospital. Nan had been told by doctors that she probably would be in hospital for about three months.

Jack and Laura drove up on a Sunday morning. The drive was about three hours. George was thrilled to see his grandchildren, as he still thought of them, even though they were twenty four and eighteen.

Laura took the small bedroom, at the top of the stairs next to her grandparents room. Then after that there was a big double room, then at the end of the hall, at the opposite end to Laura's room, an even smaller room that Jack was going to sleep in.

Laura hadn't been here in over two years and as she checked around, loads of childhood memories came flooding back. The family had often stayed here when she was younger. One thought that hit her was the night time. She remembered that out here by the sea the nights were very dark and this old cottage seemed even darker. Often at night she had got spooked by the slightest noise in the pitch black and had crawled off to the double room where her parents slept or the room where her brother slept. She would climb into bed with them, cuddle up and feel so much safer.

So when she went to bed that first Sunday night she was already nervous. She put on a t shirt and shorts and lay still in the darkness, afraid to lie on her side or close her eyes. That first night seemed an eternity and at breakfast she told her granddad and her brother that she had slept badly.

"I kept expecting you to come into my room. I knew you'd be scared," laughed Jack.

Laura had thought of doing just that several times during the night, but didn't because she thought her big brother would think she was still just a kid, and also because it might be a bit awkward. They weren't children any more, after all.

On the Monday they all went for a walk in the morning before driving to the hospital to see Nan after lunch. On the way back they bought some supplies before Laura cooked dinner. In the evening Laura spoke to her boyfriend Darren on the phone, before they all headed off to bed. Laura read for awhile, wearing her t shirt and shorts. She switched off the light and lay in bed, again terrified if the dark. Eventually she gave up, swallowed her pride, and walked down the hall to the room her brother was in. Jack looked up when he heard the knock on his door. His sister opened it and stepped in.

"Is it Ok?" she whispered.

Jack smiled and pulled back the sheets. Laura climbed in and rolled over onto her side, her back to her brother. With Jack there she felt so much safer and was soon asleep. Laura woke up the next morning, with sunlight beaming through the curtains. Her brother was lying next to her, his arm draped over her stomach and his hard cock poking her ass. She realized that he had an erection and she gently pushed herself away from him, before getting out of bed. She pulled back the sheets and smiled as she saw the tent in his boxer shorts. She quickly left the room, not wanting granddad to catch her in the same bed as her brother.

The next night Laura again read a book in her own bed. She was feeling horny and thinking about Darren who had phoned her that evening. She slipped her hand into her panties and rubbed herself to an orgasm, as quietly as possible. After that she went to her brother's room to sleep. It was a hot night and Jack was just wearing boxers. Again she fell asleep quickly. She woke up during the night, when it was still dark, and was surprised that to find that she was still horny. She quietly slipped her hand into her panties and began touching her pussy. Terrified of getting caught, she crept out to the bathroom and masturbated there.

"What's wrong with me? I feel so horny here,"she wondered to herself.

Back at home with her boyfriend Laura enjoyed a very enjoyable sex life. She was surprised that Darren had opened up a side to her that she didn't know existed. She was a horny little devil and also quite perverted. She couldn't get enough sex. Now here at her grandparents house she wondered how she was going to cope for four or five weeks without a cock to satisfy her. Oh well lots of masturbation.

She went back to Jack's room and got into bed.

"You Ok? I thought I heard you get up?"

"Sorry just needed to pee," she replied.

The next morning Jack and Laura went for a walk along the beach. They met a man who introduced himself as Henry Meed, their grandparents nearest neighbor. He pointed to his house which was about half a mile from their grandparent's house.

"I remember you two. Jack and Louise isn't it?"

"Laura."

"Sorry, Laura."

They told him they were staying for the summer.

"Oh you must meet Megan my daughter. She's about your age . It will be nice for her to meet someone her own age and she can show you around if you want."

They agreed that would be great and carried on walking. In the afternoon they all went to visit Nan. That night Laura again spoke to Darren on the phone. She went to bed, read, and masturbated before going to Jack's room. Wearing a vest and panties she climbed in next to him. Normally in the morning she would get up before granddad and go back to her own room. That morning however she slept through. A knock on the door woke her up. Jack was already awake. George came in, carrying a tray with two cups of coffee.

"You scared me this morning, I went in your room and you weren't there. I guessed you'd be here," their grandfather laughed.

"Sorry, got spooked I guess,"she blushed.

She got up and went to the bathroom. Her brother and grandfather stared at her panty clad ass as she left the room. George looked at his grandson curiously. She came back in. George had gone downstairs. She got back into bed and chatted to Jack as they drank their coffee.

"Do you mind me coming into your bed?" Laura asked her brother.

"No it's fine. Hopefully it won't last all summer though," he laughed.

Laura kissed him on the cheek as she got up and skipped to her own room. The next night Laura received a text picture from Darren. It was a photo of him naked with an erection. She sighed dreamily as she stared at it. In bed she stripped naked and rubbed her cunt furiously, enjoying her best orgasm since coming here. After reading for a bit she put on a vest and panties and went to Jack's room. He was still awake. She climbed in and they cuddled. He was just wearing shorts and she was sure she could feel his semi hard cock against her leg.

Jack looked at his sister as she entered his room. Damn she looks hot again. That morning she had got out of his bed and he and his grandfather had stared at her ass in her tight little panties. He had no idea she only wore panties and a vest in his bed. After she had gone back to her room he had jacked off thinking about her ass.

Jack had no proper girlfriend but at university he enjoyed a fairly decent sex life involving one night stands, drunken fumbles and a couple of very drunken threesomes. His little sister was just that. His little sister. He still thought of her as a little kid. And with her needing to sleep in his room because she was still scared of the dark, well that seemed to confirm she was still a child. But then he saw her fine panty clad ass. Oh my!

Laura climbed in, but instead of lying down to sleep, she cuddled her big brother. Shit this was hot thought Jack as his cock responded. After a brief cuddle they lay down to sleep. Jack could hardly sleep, thinking about the scantily dressed teenage girl next to him. He was missing sex, and feeling horny.

Laura couldn't sleep. She was still thinking about Darren's naked photo, and despite her earlier masturbation, she was feeling horny. She slipped her hand into her panties and began to rub her pussy. As she got more turned on she thought of going to the bathroom, but she realized the act of playing with herself while her brother slept in bed next to her was adding to the excitement and making her even hornier. She slipped her panties down, and off, kicking them onto the floor next to the bed. She thought if she was quiet and calm enough she could get away with doing this while Jack slept. Damn that was a hot thought.

Jack lay awake, aware of slight movement next to him. His sister was breathing hard and fast. The increasingly rhythmic movement and a little moan confirmed what he thought. His hard cock twitched as he realized she was masturbating. He listened, feeling so horny. Had he ever felt hornier, he wondered. My little sister! Finally he could stand it no more. He silently slipped his hand down inside his boxers and around his cock.

"Are you doing what I think you're doing?" he whispered.

Laura stopped, shocked. Oh fuck!

"Err...no. I mean no, of course not."

"What are you doing then?"

"Nothing, I was just..."

"It's Ok. I'm doing it too."

"Huh?" asked Laura.

"I'm playing with myself."

"Jack?"

"It's hot, I'm horny and I'm missing having any sort of sex life, just like you."

"Oh."

"What are you thinking of?" Jack asked.

"Jack I can't. Not with you here. It's embarrassing. "

"Just tell me, what are you thinking about? "

"Darren. He sent me a nude picture."

"Oh."

Jack pulled his shorts down and stroked his cock, much more blatantly now. Laura looked at the sheet above her brother's waist moving in time to his stroking. She resumed her own rubbing of her pussy. Brother and sister lay together, masturbating under the sheets. Finally Jack grunted as he came, shot after shot of sperm hitting the sheets. Laura came moments later, moaning and shaking. Jack climbed out of bed, in the darkness, and went to the bathroom, still naked, to get some tissues. When he came back in Laura was standing by the bed. She had switched the bedside lamp on, and was standing wearing just her vest. Jack looked at her naked pussy as she stared at his nude body, in particular his limp cock.

"Oh. Now this is awkward. I just wanked in front of my brother, " she laughed, blushing.

"Err? I'm not sure how that came about. Sorry."

"It's Ok. Err, what now?" Laura asked.

"Sleep," replied Jack, climbing into bed still naked.

Laura climbed back in, wearing just her vest, as her brother turned off the light. Satisfied by their game the two siblings fell asleep. Laura woke up hearing her grandfather going downstairs. Remembering where she was and what had happened she got up and ran to her room. A few minutes later her grandfather appeared with a cup of coffee.

"You keep me guessing where you are! I went into your brother's room first but you weren't there," he laughed.

"Sorry granddad, I slept in here last night. Must've been too tired to get scared!"

She sat up and took her cup. Her grandfather left her room and went downstairs to prepare breakfast. After he had gone Laura got up and went back to Jack's room, having put on a pair of shorts first.

"Morning bro," she smiled, climbing into his bed.

"Morning. You Ok? "

"Yeah, you? "

"Sure. I just remembered what happened last night. Are you Ok with it. I'm sorry if I embarrassed you," he told her.

No it's ok, honest. Anyway I started it," she laughed.

"I know, but it's a bit weird. Jacking off in front of each other. Maybe we shouldn't have."

"Don't worry. I know it's a bit weird. Let's just put it down to experience. I know it's wrong, and I don't want you to think I'm a bit slutty or anything, but it just happened. "

"I would never think that about you."

"Thanks Jack."

"We're bad aren't we?" he laughed.

"Very. You probably think I'm a real dirty bitch."

"No, you're ok. Besides it's not the first time I've jacked off since I got here," Jack said.

"No?"

"No, I did it yesterday morning too."

"Do you want to know a secret? I've done it nearly every night. I go to bed, read a bit and then play with myself before I try to sleep. "

"Wow!"

"I know..."

"So my little sister cums in her bed then just after that comes into my bed?"

"Err...suppose, yeah."

"Laura, I'm feeling horny right now."

Laura looked down at the sheet and saw the tent.

"Shit, you're still naked aren't you?"

He nodded.

"Do you want to do it again? Now?" she asked.

He nodded.

"You?"

"Yeah I guess. "

Jack slipped his hand around his cock. Laura hesitated.

"Wait. I can't. Not here with you. Not with you watching. Sorry I can't. "

"It's ok."

"I want to but you're my brother, it's just too weird. I'll go to my own room and do it there."

Before he could say anything Laura got up and left the room.

They had breakfast then shortly after they had both showered there was a knock on the door. It was the neighbor, Henry Meed, with a short, pretty looking girl. George answered the door. After the two men had chatted briefly Laura and Jack were beckoned to meet Megan.

"Hi, Jack. Laura. This is my daughter, Megan," Henry told them.

Megan held out her hand shyly to greet them. After a bit of small talk the three of them went for a walk down to the beach. They talked about the area. About school. Megan told them she didn't have a lot of friends. About how her mother had died when she was four leaving just her and her dad in the house. They had noticed a massive scar running up her left arm.

"That's ok. Everyone looks at that. I got a bit too close to some farm machinery when I was two. That scar seems to be the only thing people notice about me," she sighed.

The three of them got on well and agreed to go into the village one evening for a drink. After lunch Jack and his grandfather went off to visit Nan in the hospital. Laura stayed and baked a cake and some giant cookies, one of her special talents. That evening the three of them watched a movie on tv, sharing a bottle of wine. Laura wore a short cropped top with thin spaghetti straps, and a pair of shorts. They went to bed. Laura read for a while before going to her brother's room. Jack was still awake, sitting up reading. She climbed into bed with him. After a while he turned the light off and they cuddled together. Laura felt his semi hard cock brushing against her leg.

"Hey! Are you horny again?" she laughed.

"Sorry, it's just, you know. Out here in the middle of nowhere I can't seem to think of anything but sex!" he joked.

"Me too. Do you want to?"

Without answering Jack rolled onto his back and slipped off his shorts. He began to stroke his cock. Laura pulled off her shorts and began to masturbate as well. Halfway through she pulled off her top, so she was naked, like her brother, although their nudity was hidden by the sheet. They both came, panting and really turned on.

"I guess that's twice now," laughed Jack.

"We must be really bad people," Laura replied.

Without putting their clothes back on they tried to sleep. Jack turned his back on his sister. She wriggled to get close to him, pressing her breasts against his bare back and draped her arm across his chest. They fell asleep. Laura woke up sometime later. It was still dark. The room was pitch black. She was now facing away from Jack and his cock was nestled in between her ass cheeks. His hand was across her stomach. Feeling horny again, she pushed her ass back into his cock, which began to stiffen. He didn't wake. Feeling really turned on and naughty, she grabbed his arm and laid his hand to rest on her right breast. Still he didn't wake. Finally she rolled onto her back, leaving his hand on her tit. She reached down and began to touch his now hard cock. With her thumb and fore finger she played with his sensitive tip.

Finally Jack woke up. He became aware of his sister's hand messing about with his penis, also realizing he was touching her boob.

"Mmmmm, feels good," he whispered.

Laura began to stroke his cock, and at the same time, with her free hand, she started to rub her pussy. Soon Jack was getting close. His breathing quickened and he moaned. Laura sat up to get a proper and firm hold on his shaft. Then he shot out several jets of semen. The first two or three landed on his stomach. The rest dribbled out onto his sister's hand. Laura brushed her hand over his stomach to wipe off his seed. Jack sat up a bit then leaned over to turn on the lamp. He was greeted by the sight of his sister sitting up naked. He looked at her breasts for the first time, and at her pussy, open and gaping as she sat with her legs folded under her. Her hand was on his stomach. Laura looked at her brother. His cock was still semi erect. He had cum on his stomach.

Jack leaned across and kissed Laura's tit. He then began licking and sucking them. Laura started to rub her pussy furiously, in full view of her brother. She came soon after and they lay together.

"Oh my god! Did that just happen? " she laughed.

"I think we got a bit carried away," Jack laughed.

"I feel so bad right now. Not in a bad way. Just naughty."

"Well that was a bit perverted. Brother and sister and all that," Jack smiled.

Jack wiped himself clean, throwing the tissues in the little bin by his bed. Then they lay together, in each others arms, and fell asleep. Laura again woke up first, hearing her grandfather going downstairs. Naked she climbed out of bed and walked to her own room, leaving her top and shorts on the floor in her brother's room.

She lay in her bed, pretending to be asleep. George came in. He brushed her bare shoulder and she stirred.

"Morning Laura, " her grandfather whispered.

She sat up as he moved past the end of her bed and opened the curtains. At the same moment he looked round to her, and she reached for her coffee, the sheets slipped down, exposing her naked breasts to her grandfather.

"Whoops! Sorry," she laughed, pulling the sheet back over her chest.

George went downstairs and Laura got out of bed and ran to her brother's room. He looked up as his nude sister came in.

"Now there's a sight," he smiled.

"I just accidentally exposed my tits to granddad!" she laughed.

She climbed into bed and they chatted.

"We are so going to go to hell," he smiled.

Once they finished their coffee and both had dressed, they had breakfast. Jack and his grandfather went off birdwatching, something they had in common with Jack's father as well. Laura put on her little black bikini, grabbed a towel and a book and walked down to the beach. She lay on her stomach and took off her bikini top.

She had only been lying there a few minutes when first a dog, then Henry Meed, appeared walking along the sand dunes above her.

"Morning Laura, " he shouted.

She returned his greeting and watched him walk towards the sea. Twenty minutes passed, and there was no sign of Henry coming back. She guessed he must have carried on around the beach back to his house, which would be the logical thing to do. Feeling horny she rolled onto her back and slipped her hand inside her bikini bottoms. Still no sign of anyone about, so she pulled her bottoms off. Now totally nude she put her book down and began to masturbate, there on the beach.

Henry Meed walked back along the dunes. Normally he would carry on along the beach, returning home that way. But he came back the way he had come, even though it was longer because he wanted to see the topless teenager again. He couldn't believe his luck earlier when he had turned the corner past George's house and spotted the granddaughter lying there. She was on her stomach so he hadn't actually seen anything but this was still a thrill. And you never know she might be on her back now. The thought excited Henry. He couldn't deny it. After all these years he still liked ogling teenage girls. Heck it was bad enough living with one.

Henry crept along the sand dunes. His dog ran about while it's owner walked slowly and quietly.

Holy fuck!! Henry stopped dead as he saw his neighbor's granddaughter. He rubbed his eyes to make sure he wasn't dreaming. He wasn't. The girl was lying on her back, on the towel, naked, rubbing her cunt furiously. He stood and stared. And he continued to stand and stare. However his dog had different ideas, and ran onto the beach and up to Laura. Henry had to move as the girl stopped her masturbation and looked around. He walked calmly along and called to his dog, then carried on walking, waving to Laura, as if this scene was something you would see every day.

For her part, everything happened too quickly. She was so far into playing with herself she hardly even noticed the dog appear. Then when the neighbor appeared she didn't have time to react. She stopped rubbing her pussy but her hand was still there when he saw her. Laura waited till he had gone out of sight then calmly resumed her game. She moaned loudly as she came. After she had her breath back she ran to the water and swam to cleanse her body of sweat and juice. She walked back to her towel, still naked, then calmly strolled back to the house. Only once she was in her room did she put some clothes on. She put on her thin cropped top with the spaghetti straps and a short, flared black skirt, that only went as far down as just below her ass cheeks. Very short.

Her grandfather and brother appeared about an hour later. They had lunch then went off to visit Nan in hospital. That evening, Megan knocked on the door, carrying three bottles of beer.

"I quite often go and watch the sunset from the beach. Usually on my own, sometimes with dad. Do you want to come?" she asked Jack and Laura.

They walked down to the beach and sat watching the sun go down.

"You're so lucky having a brother. I wish I did," Megan said to Laura.

"It's ok, can be annoying sometimes, can't you?" laughed Laura, nudging her brother in the ribs.

They sat a while longer. When she headed off to her house Megan gave them both a hug.

"She seems so lonely, " whispered Jack.

Back home they began to watch a movie. Jack persuaded his grandfather to get out his bottle of whisky. Laura had never tasted whisky before but begged her grandfather to let her try it. He poured her a small glass. George was sitting on the armchair. Jack and Laura sat on the couch opposite. Laura was directly opposite her grandfather. As she took her first tiny sip, her face screwed up in disgust.

"Christ that's horrible!" she said.

The two men laughed at her reaction. She was still wearing her short black skirt and no panties. George had had a long and tiring day. He had been birdwatching with his grandson and visited his wife in hospital. Only now as he stared at his granddaughter's long, smooth, bare legs did he remember the brief but tantalizing glimpse of her naked breasts that morning. Just for a second, but that was enough. He admonished himself for even thinking about it. His own granddaughter! How could he? But they looked so nice. He realized that this wasn't the first time he had been looking at her since she arrived this summer. This teenage girl. Her slim smooth body and skin. Firm and nubile. Her long brown hair. Only eighteen, her body was still that of a girl, not yet that of a woman. And he stared at her legs. Right up to the hem of her skirt. And even then, with so short a skirt, the hint of her ass cheeks as she sat opposite him.

Laura was feeling horny again. Just thinking of her day. Masturbating with her brother. Then masturbating her brother while he sucked her titties. Then being caught by the neighbor on the beach. And accidentally exposing her breasts to granddad. All these things, potentially embarrassing, seemed so exciting. Dirty. Naughty. But god she wanted more. And now she realized her grandfather was watching her. Checking out her legs. And she was not wearing panties. And a very very short skirt.

She took another tiny sip of whisky. Again she screwed up her face. She repeated this act several times. The men never tired of laughing with her and at her. She did it again but this time she punched her arm out in disgust. It wasn't really disgust. She was getting used to the taste and beginning to like it. Also it was going straight to her head and her legs. One more gulp and she kicked her leg out. She left it straight out in front of her. The movie would be over in ten minutes. George went up to the bathroom. While he was out she stretched her left leg, leaving it dangling over the arm at the end of the couch. Her other leg she left sticking out in front of her. George came in and sat down. He looked at the tv, only looking back at Laura when she took another sip of whisky. He stared at her. He didn't know if she knew but her legs were spread wide and he could see straight up her ridiculously short skirt. And even with his imperfect eyesight he could see she was not wearing underwear. It took him a moment to realize he was staring straight at her vagina. He was not used to the lack of hair. In his younger days, when he gained his experience with women they all had hairy vaginas. Pubic hair was standard and accepted. He was not at all used to this twenty first century fad of shaving pubic hair off. But he looked and saw his granddaughter had a bald smooth slit. He saw her pussy lips glistening in the glow of the light.

Laura couldn't believe what she was doing. She could feel the breeze around her pussy and knew she was showing her most secret place to her own grandfather. Her own grandfather! What was she thinking of? But God it felt so good. So naughty but so good!

The movie finished and they went to bed. Before she got into bed she went into granddad's room and kissed him goodnight. Something she rarely did. She went to her own room and stripped naked then walked down to Jack's room. He was sitting on his bed, about to get in when she walked in. Like her he didn't have a stitch of clothing on. They stared at each other. They smiled then climbed silently into bed. Surprisingly they cuddled up and Laura fell fast asleep. Jack looked at his naked sister. He couldn't believe she had fallen asleep before they had jacked off together. Must be the whisky.

Laura woke up upon hearing her grandfather open the bedroom door. Had she slept all night? He walked in, putting the tray carrying two cups on the table by the door. She looked down and realized she was naked under the sheets. George went to the window and opened the curtain.

"Another sunny day but they say we're in for a storm tonight."

He went back to the tray and put one cup on the table by his grandson and one by Laura. She sat up again, deliberately exposing her breasts. George looked at her. Jack sat up and George noticed the penis shaped tent in the sheets.

"Are they both naked? " he thought to himself. He left the room.

After he had gone Jack got out of bed and walked naked to the window. He looked out. Laura got up and stood behind her brother. She pressed against him and ran her hands along his chest, over his stomach and down to his waist. She took hold if his cock and began to stroke it. Jack turned round and looked at his kid sister. She dropped to her knees and took his cock in her mouth wrapping her lips around it. He held her head as she bobbed up and down on his member.

"Fuck I'm cumming!" he exclaimed.

Laura swallowed all his cum, licking his cock clean.

"Now that was VERY naughty," he laughed.

"Guess that means we will never be a normal brother and sister again!" smiled Laura.

"Good, if it means doing that again!" Jack exclaimed.

They dressed and had breakfast. George stayed indoors while his grandchildren went to the beach. Laura wore her black bikini. Jack wore a pair of shorts. George watched as the two of them crossed the lawn towards the dunes and stepped down to the beach.

He couldn't explain it but George had an overwhelming desire to watch his grandchildren. He went to his bedroom and took his birdwatching binoculars out of the drawer. Then rushing as fast as his sixty eight year old body would allow he went upstairs to the attic. He stood by the tiny attic window and looked through the binoculars. After a bit of focusing he found what he was looking for. He was confused by their behavior. As children they had slept in the same bed at his house but now they were adults. And Laura had been topless this morning. Maybe naked. He was sure Jack was naked. Brother and sister naked together in bed?

Wham! He found what he wanted. He trained his binoculars on the two of them on the beach. Still in their swimwear, they were running about on the sand chasing a ball. When they caught up with each other they would push and shove. Tickle and play fight, throwing each other onto the sand. Actual normal sibling behavior he thought. Maybe I'm wrong. Then they swam a bit then laid down in the sand and and read their books. Ages passed and George was getting bored. After about an hour they stood up. Jack walked towards the sea. Boring. Laura stood up but then paused and unhooked her bikini top. At last thought her grandfather. He focused the binoculars on her naked breasts, that he had seen so briefly a couple of times that week. Laura ran to the sea and the two siblings began wrestling a bit. Laura grabbed her brother from behind and yanked down his shorts. He made no effort to pull them up. She walked back to the beach and he followed her. When she got to their towels she pulled off her bikini bottoms. My god he thought they do strip naked together. Jack caught up and stood by her. Through his binoculars George watched in disbelief as his granddaughter took hold of her brother's cock and began stroking it. Once it was hard she leaned closer and began sucking it. George couldn't believe his own grandchildren were behaving like this. My god, do their parents know. He watched amazed as Jack came in his sister's mouth.

All the time she was sucking his cock, Jack was stroking his sister's nipples. Now he had cum he sat down. Laura sat opposite him and proceeded to rub her pussy. From his vantage point up in the attic, George didn't have the best angle but he could tell what was going on. He watch his granddaughter shudder as she reached her orgasm.

George put down his binoculars and rubbed his eyes. He could hardly believe what he'd seen. Sure he had a suspicion but he thought and maybe hoped that was just his dirty old mind. He was in shock and didn't really know how to react. Two things he noticed were that although he was shocked he wasn't disgusted. Secondly he realized he had an erection. He sat down and thought about what had happened. He might be an old man but he wasn't a fool, nor was he narrow minded enough to believe that such things didn't happen. He knew incest was a real thing, but his own grandchildren? Crazy yes but disgusting, no. Not to him anyway. In fact the more he thought about it the more he found himself getting turned on.

Jack and Laura stood up and went back into the sea to swim. After they sat down and read for a bit before getting dressed and returning to the house.

As they ate lunch with their grandfather there was a knock on the door. Megan asked them if they wanted to walk into the village that evening for a couple of beers. They agreed. They went of to see Nan, then Laura cooked dinner. All the while their grandfather tried to act as normally as possible around them.

The evening was a great success. They had a good time with Megan and really got to know her. Far from being a quiet and meek girl with nothing to say for herself, she had a great sense of humor. She told them so much gossip about the people in the area and at her school. She had no boyfriend at the moment but when they pressed she admitted that she wasn't a virgin.

"Who was he?" asked Laura.

She wouldn't tell. Couldn't tell, it seemed. She asked the siblings about their lives. Laura told her about Darren, her boyfriend, and showed her a photo. Not the naked photo! Jack told her about university and a few tales of his sexual escapades without going into too much detail.

"You're very close you two. I wish I had a brother I could be close to. Don't you ever fight?" Megan asked.

"We used to, not so much now. We don't see each other much because he's away most of the year. So when we see each other we get on really well.This summer has been great. We've got real close. Closer than we've ever been," smiled Laura.

Jack held her hand when she said that. They walked Megan back to her house. After watching a bit of tv with their grandfather they went off to bed. Laura went to her own room and stripped naked. She read for a while then got up and went to Jack's room. She climbed into bed and immediately began playing with his cock. She jerked him off then did herself while he watched.

"I love watching you cum, " said her brother.

They fell asleep in each other's arms. Laura woke up at about five in the morning. Daylight was just coming through the window. Her brother's cock was prodding her ass. She reached behind and started to stroke it. Rolling over onto her back, she let her brother touch her pussy for the first time. Although they had masturbated together he had never before touched her down there. His fingers penetrated her pussy lips and he rubbed her. She came, moaning loudly.

When she heard her grandfather get up Laura went to her own room. She climbed into bed and pulled the sheets up to cover her nudity. But she was still feeling naughty and decided to do something mad. She pushed the bed sheets down to her ankles. Rolling over onto her left side she stretched out her left leg, and bent her right leg at the knee and the hip.

Moments later her door opened and her grandfather walked in. Pretending to be asleep she peeked out of the corner of her eye. George stopped dead in his tracks as he saw his naked granddaughter. He put her coffee onto her bedside table and touched her bare shoulder. She didn't move. He walked round the bed and to the window where he opened the curtain. Sunlight streamed in.

"Laura," he whispered.

Again no reaction.

He walked back to her bed, looking at her bare ass and touched her shoulder again.

"Laura," he whispered again.

She stirred. She opened her eyes, turned her head to face her grandfather and stretched out her legs. She then stretched her arms above her head as she rolled onto her back. Lazily and slowly she pulled the sheets up to cover herself.

"Morning granddad, what's the weather like?"

"Sunny again. No sign of that storm they keep promising."

"That's good, what should we do today?" she asked.

"I asked your brother and he just said it depended on what you're doing."

"Oh ok. Oh well we'll see."

George left the room and went to his own bedroom. Laura giggled to herself as she thought how crazy it was that she had let her own grandfather see her totally nude. She felt really dirty but also really turned on. She pushed back the sheets and sat up and spread her legs wide to masturbate. She was rubbing herself furiously, completely caught up in her pleasure when her door opened again. Her grandfather stood in the doorway staring at her. She stopped rubbing but her hand remained on her clit.

George stared at her, completely lost for words and forgetting what he came in to say. Laura made no effort to cover herself or hide what she had been doing. She was just too horny to care. Eventually her grandfather composed himself and was able to speak.

"I thought maybe I might go birdwatching this morning. I wonder if Jack might come too. Perhaps after we see your grandmother this afternoon we could stay in town and I'll treat you both to dinner," he suggested.

"That sounds lovely granddad, thanks. I might come birdwatching too. I haven't got a clue what I'll be looking at but maybe you two could guide me."

As she spoke she subconsciously began rubbing her pussy again, gently but enough for her grandfather to notice.

"Lovely, ok well come down to breakfast when you're. ...Err. ...ready," he said, trying not to look at her naked body and in particular what her right hand was doing. He knew full well what it was doing and he also knew he was getting an erection.

George left her room and went downstairs to the kitchen to prepare breakfast. He couldn't think straight nor get the image of his naked granddaughter out of his head.

Laura came then went to shower. As she came out she bumped into her brother who was going to shower. He was naked. She smiled at him and started stroking his cock. She bent down and gave him a blowjob before going back to her room. She put on an old faded yellow t shirt and her short black skirt and went downstairs.

After breakfast the three of them headed off to go birdwatching. George explained to Laura that if they kept walking the other side of the inlet, follow the beach for about twenty minutes then turn inland they would reach a clump of trees. They had to go through the trees and they would eventually come to a lake. There were some more trees and a small wooden hut that was used as a bird hide."What's a bird hide?" asked Laura.

They explained to her. Finally they reached the lake after about a forty five minute walk. They opened the outer door to the hide, then the inner door. It was dark inside. George and Jack opened a couple of wooden flaps and sat on the wooden bench.

"You just look through and keep real silent," Jack explained to his sister.

Laura sat for a while. Then she moved further down the long wooden bench and sat looking out a flap. She had no idea what she was looking for. She saw a lot of birds but to her one bird was much the same as any other.

Jack moved along to sit next to his sister. The hide was still quite dark and very quiet. The only noise was the sound of birdsong. Their grandfather was at the other end of the bench peering through his binoculars. Jack put his hand on his sister's leg and stroked along her thigh. He slipped his hand under her skirt and found she was not wearing any panties. He began to stroke her pussy. Laura began to moan softly as her brother fingered her cunt.

George sat looking intently at the birds. He stopped for a moment and looked back into the hide. It was dark. He realized Jack and Laura were down the far end of the bench but he couldn't see much. Jack became aware that his grandfather was looking towards them and started explaining to his sister the different types of birds. He pretended to point out birds while with his other hand he was playing with her vagina. George looked back through his binoculars at the lake. Laura pulled her shirt up and her brother started sucking her nipples. She pulled her skirt up so it was bunched around her stomach and let her brother do whatever he wanted. She moaned more loudly as she got closer to cumming. George looked at them and realized what they were doing. Finally Laura came, moaning loudly as she did so. Jack slid back down to his grandfather and they resumed birdwatching. After another hour or so they went back to the house and ate lunch. They visited Nan in hospital and went out for dinner, as George had suggested. On the way home the wind picked up and it started raining.

"Looks like that storm is here at last. Could be a bumpy night," laughed George.

At bedtime Laura went to her room. She stripped naked and got into bed and began reading. She soon felt a bit cold so she got up and found an old t shirt to wear. It was very old. About seven years old, but one of her favorites. Faded, torn, shrunken and a bit short. Just above her navel short. An extremely faded image of Kurt Cobain on the front. She got back into bed, hearing a couple of rumbles of thunder in the distance. Unexpectedly she fell asleep, having intended to visit her brother.

She woke up about an hour later as a flash of lightning was followed by a huge crash of thunder. She lay in the darkness listening to the storm. The next burst really shook her up. As the thundered roared outside she let out a scream. She immediately felt stupid and told herself to grow up, but her grandfather had heard her scream. He got out of bed and went to her room.

"Are you alright Laura? I heard you scream."

"Sorry granddad, just the thunder freaked me out."

George walked over to her window and looked out.

"I think this is the center of it. It will probably have passed us in an hour or so," he said.

Feeling bolder from her grandfather's presence, she got out of bed and stood next to him at the window. He put his arm around her and squeezed her tight. She cuddled up to him. She didn't care at this point that she was naked from the navel down. As they watched the lightning in the night sky he suggested she could come in with him into his bed if she was scared.

"That's if you wouldn't rather be in with Jack," he said.

Laura followed her grandfather to his room. He climbed into bed, watching her as she walked round to the far side of the bed. He shook his head in wonder as he realized she was just wearing a short t shirt and nothing else. He stared at her cute little ass as she got into bed. Laura cuddled up to her grandfather. They lay together in silence listening to the storm outside. After a while she rolled over, so she now had her back to her grandfather. He moved closer to her and wrapped his arm around her, draping it across her stomach. For whatever reason Laura felt horny again. She backed her ass against his groin. Then she went a bit further. She lifted her t shirt up to her neck and took her grandfather's hand and placed it on her tit.

George sighed as his hand touched his granddaughter's bare breast. He lay quietly, not moving his hand and within minutes both of them were fast asleep. George woke up first. His body was now facing away from Laura. He rolled over to look at her. She sensed his movement and woke up as well. George began to get up but Laura reached out and held his arm.

"Mmmmm not yet, Granddad, just ten more minutes please. It's so warm and comfy here with you. Please," she begged.

George sighed. He lay back down. Laura rolled over onto her side.

"Cuddle me please."

George edged closer to his granddaughter and draped his arm across her stomach. Laura held his hand and placed it onto her breast. At first George just left his hand where she had put it, as he had during the night. After a few moments temptation took over and he slowly moved his fingers, feeling her naked breast. He stroked her nipples and rolled them between his thumb and fore finger. He squeezed her breasts. Laura moaned gently at his touch. His hand left her chest and slid slowly down over her ribs and her stomach until it reached between her legs. He stopped briefly as his fingertips rested on her pussy lips. George then gradually applied pressure, slipping a finger past her lips and into her slick wet cunt. Laura moaned again as he did so.

Suddenly George stopped and pulled his hand away from her.

"Time to get up," he announced.

He stood up and walked towards the door. Laura noticed a bulge tenting in his pajama trousers. When he had gone she masturbated before getting up and going to her own room. He brought her cup of coffee, smiling at her, and sat on her bed.

"Sorry about that, I got a bit carried away," he told her.

"That's ok granddad I started it."

They talked for a while. George admitted that he had watched her and her brother on the beach and told her what he had seen. Laura blushed as she told him about her relationship with her brother. To make her grandfather feel more relaxed about it she lied that it had started before they came to stay at his house. She also lied by saying that she and Jack had actually had sex many times, even though actually they hadn't gone that far. Yet.

"Goodness, I mean obviously you hear about things happening but I never actually imagined my own grandchildren doing it," he pondered.

"Are you alright about it? I mean a lot of people would find it pretty disgusting," she asked.

"I suppose as long as you're happy and careful it's really none of my business. Do your parents know?"

Laura shook her head.

"Please don't tell them," she pleaded.

He assured her he wouldn't.

After her grandfather had left the room Laura took her coffee and walked to her brother's room. Jack smiled as he saw his sister appear in a t shirt and panties.

"Not naked? That's unusual," he joked.

"Granddad knows that we are messing around with each other," she said, climbing into bed.

"How?"

"I told him. I mean, he kinda guessed anyway. It's not difficult. We seem to share a bed every night and don't wear much clothes in bed. He's not stupid."

"Guess so. Was he ok about it? I mean he's not gonna tell on us or anything?" asked Jack.

"No. He seems cool about it. Well I don't know if that's the right word. He seems curious."

"Curious?"

"Yeah, as if it's a generational thing. Like people have sex nowadays with anybody. But in his youth it was more...restrained..."

"Ok. I think," pondered Jack.

"Also, he kinda thinks we have full sex. He sort of assumes. I couldn't be bothered to explain that we don't. It didn't seem to matter."

"Ok?" puzzled Jack, still trying to get his head around the idea that his grandfather knew he was messing around with his sister.

They lay in bed drinking their coffee. Jack started touching his sister's tits and then moved down to lick her pussy. When she had cum she began to suck his cock, but before she could finish their grandfather came into the room. He stopped suddenly when he saw what Laura was doing. She paused, her lips still close to Jack's cock, which she still held in her hand.

"Err...err...I just wanted to tell you that breakfast is ready," George mumbled, trying to ignore their position.

"Thanks granddad. We'll be down soon. Just finishing this," Laura giggled, before sinking her lips back round her brother's cock.

George quickly turned and left the room.

"You're crazy," laughed Jack.

After breakfast they all went for a walk along the beach, before visiting Nan after lunch. Laura had a headache for most of the day and that evening her period came on. That night and the next she slept in her own room. On Friday evening they had eaten dinner and were just settling down to watch tv when they heard a car pull up outside.

Laura stood up and looked out.

"Oh my god! It's mum and dad!" she exclaimed.

"Mum and dad?" asked Jack.

"Yeah. What are they doing here?" Laura asked, looking worried.

"They wanted to surprise you. They're here for the weekend," explained their grandfather.

Their parents came in and they all sat down, drinking and chatting. Bob and Alice asked their 'children' what they had been doing so far. Jack and Laura looked a bit nervous.

"Just relaxing. Walking, birdwatching and messing about on the beach. It's been great," smiled Jack.

"Laura? Birdwatching?" joked Alice.

"I did go once mum. Didn't really understand what all the fuss was about," Laura responded.

"Laura's been doing a lot of sunbathing," joked Jack.

"Actually she's been great. Really helpful. She's done most of the cooking. Baked some lovely cakes. It's been a joy having her here. Both of them," George added.

"Really dad? My two kids?" joked Bob to his father.

At breakfast next morning they were still full of conversation.

"So, Laura, have you managed to stick to your own bed?" asked her mother.

"Mum!" Laura exclaimed, turning a deep shade of red.

"Well you always used to be so scared of the dark. Never a night went by when you wouldn't creep into bed with someone else," laughed Alice.

"I'm much better now mum. Don't embarrass me," Laura answered, looking nervously at her brother and grandfather.

"I'd kill her if she came anywhere near my room!" laughed Jack.

In the afternoon they all went to see Nan. On Sunday they walked on the beach in the morning before going back to the hospital in the afternoon. Bob and Alice left for home late Sunday afternoon, leaving their son and daughter for a few more weeks. By Monday Laura had finished her period. That evening Megan called round with a few cans of beer, and they walked down to the beach. Laura was now feeling really horny. She wore a short, flowery, dress, and nothing underneath. As they drank beer, chatted and watched the sun set, she stroked her brother's thigh, aware that Megan was watching her do this. Jack responded by putting his arm around her shoulders. Casually his hand drifted down to her chest and he began to rub her tit though the dress.

Megan watched this, trying not to make her observations obvious. Laura then turned up the heat by lifting up the front of her dress and rubbing her pussy. Megan gasped at this. Then Jack pulled down his shorts and revealed his erect penis.

Megan looked stunned. Eventually she spoke.

"You two...what...I mean...what...?"

"Sorry. We didn't mean to embarrass you. We're both so horny. We often get off together," explained Jack.

"What?!?" asked Megan, smiling rather than looking disgusted.

"We masturbate together. It's fun," answered Laura.

"I noticed you seemed close but..." replied Megan

"Sorry..." Jack started.

"No it's...ok...I just..." Megan hesitated.

"We are very close. Very close," Laura added, smiling.

"Wow, that's so...cool," Megan whispered.

"You're not shocked?" asked Jack.

"Well I am, but it's ok. It's kinda...good..."

"Good?" asked Laura.

"Mmmm...I can't explain, but I really like that you two...do it..."

"Why don't you join in? Get yourself off? With us?" Laura asked.

"Oh no I couldn't. Not yet anyway. Maybe another time. Can I just watch?"

"If you like. No pressure. But please don't tell anyone. Not your dad. No one," added Jack.

"No don't worry. It's a secret. I know how to keep secrets."

Jack and Laura stripped naked and began to masturbate each other. Megan stared. Eventually her own desires began to show themselves. She slipped a hand inside her bikini top and began toying with her breast. She watched as her friends reached their orgasms, then blushed as they watched her slide her shorts down and finger her own pussy.

"I'm so ashamed," she smiled as they watched her cum.

"Don't be. It's lovely. You're lovely," said Laura.

"Thanks. Actually, it was kinda cool, doing it together," Megan laughed.

They dressed and walked back towards the houses. After they had parted Laura looked at Jack.

"That was weird you know. When she found out our little secret she didn't freak out or anything. She seemed...ok..." puzzled Laura.

"I noticed that. She seemed sort of...I don't know...relieved," Jack answered.

When they arrived back at the house Laura went to shower. She returned to the living room wearing a cropped top and white panties. Her grandfather was in his armchair asleep so she sat opposite him on the couch next to her brother. After a while she took off her panties, folding her legs under her. George woke up and went off to bed. Jack and Laura soon followed.

In her brother's bed, Laura removed her vest so she was naked. Jack stripped off too. Laura climbed on top of him, straddling him, then lowered her pussy onto her brother's penis.

"Are you sure?" he asked, looking at her.

"We've done everything else. I need your cock in me so badly. Please!"

"That's good. I really want to fuck you!" her brother laughed.

He pushed his cock as far inside her as it would go. They thrust against each other, pounding out a rhythm.

"Oh god yes that's it," Laura moaned.

"Do you like it?" Jack groaned.

"OH GOD OH GOD YES I LOVE YOU!"

"LAURA OH GOD YES!"

"JACK OH GOD YES THAT'S IT FUCK ME MAKE ME CUM!!"

"OH GOD LAURA I LOVE YOU I LOVE MY LITTLE SISTER YOU'RE THE BEST!!"

They both moaned and panted as they continued to fuck. Finally they both came.

"Now we really are bad," laughed Jack.

"Mmmm that was so naughty," Laura smiled.

Finally they fell asleep. Laura woke up sometime during the night. She woke up her brother and they had sex again.

"Now that we've started this I guess we're not gonna stop," Jack said.

"Mmmm I hope not."

The next day was a busy day, with shopping for groceries and visiting Nan in hospital. In the evening the telephone rang. George answered it. It was his other son, Mike.

"That was your Uncle Mike. He's coming to stay on Friday night. With his wife, err, thingy," George stuttered.

"Aunt Sara," Jack helped him out.

"Great," said Laura, sarcastically.

"They're staying till Tuesday morning."

"Great," repeated Laura.

She was a bit cautious around her Uncle Mike. Laura had noticed over the last three or four years he looked at her, quite a lot. He had never said or done anything but she felt a bit uneasy in his company. As for Aunt Sara. She was Mike's second wife, and at thirty four, ten years younger than Mike. Not just Laura, but most in the family felt she tried just a BIT too hard to fit in and be a part of the family. The result was that it was difficult to relax around her, as she was always fussing about.

For the next few nights Jack and Laura had sex two or three times a night. On the Thursday evening they also enjoyed another session of masturbation on the beach with Megan, who stripped completely nude this time. Uncle Mike and Aunt Sara arrived on Friday evening. Laura cooked them dinner and Sara immediately pissed her off by criticizing her cooking, complaining that there was too much pepper in the sauce. Laura slept in her own room that night, going to bed in a terrible mood. Jack and her had decided it was far too risky to sleep together with their uncle in the house, as he was quite nosy and also very close to their father. She was seriously missing her brother's cock.

On Saturday they all went for a walk along the beach before Mike and Sara went to visit Nan in hospital in the afternoon. After dinner Megan called round and Jack and Laura went with her to watch the sunset.

"So you don't like your Aunt and Uncle?" asked Megan, stripping naked.

"No, she's a bitch. His first wife, our Aunt Lisa, was much nicer," explained Jack.

"What about your uncle?"

"He's ok. Laura think he's a bit of a perv," answered Jack again.

"Why?"

"Well, it's hard to explain. I get the sense that he watches me," Laura began.

"Doing what?"

"Nothing, but whenever he's with us he always seems to be looking at me. You know, like eyeing me up."

"Has he ever done anything? Touched you or said something?"

"No, never."

"Maybe it's just your imagination."

"That's what I always tell her," laughed Jack, stroking Megan's tits.

"Why don't you test him out? You're always walking around your grandfather's house in next to nothing. See if he tries anything," suggested Megan.

"Mmmm, maybe, but it's kinda hard with that bitch hanging around all the time," moaned Laura, as she rubbed her pussy.

Megan leaned over and began sucking Jack's cock. Laura knelt behind their friend and slipped a finger into Megan's vagina. She rubbed Megan hard. Then they swapped places and Laura knelt between Megan's legs and licked her cunt while Jack fucked his sister from behind. Again they changed places so Megan was now licking Laura's pussy and getting fucked by Jack.

When they had all cum, Jack inside Megan, they got dressed and lay on the beach for a while. Laura was wearing her short, flowery dress, and no underwear. They all walked back, Megan to her house.

"Did you mind me fucking Megan?" Jack asked his sister as they approached their grandfather's house.

"Doesn't bother me. As long as I get your cock inside me as much as possible I don't mind sharing you. We're only here for another couple of weeks anyway," Laura replied.

Indoors their grandfather, aunt and uncle were watching tv. George was in his armchair. Mike and Sara were on the couch. Jack sat in the other armchair, while Laura went to her room to put on some body spray. She still wore her dress and no underwear. She entered the living room and studied the seating arrangement. The only place to sit was on the couch next to her uncle or on the floor. She sat down next to Mike and began to watch the film. Feeling a bit tired, after a while she leaned her head against him and relaxed. A little while later, Mike put his arm around her waist and rested his hand on her stomach.

Laura flinched slightly at his touch. She thought about what Megan and Jack had suggested, and in her mind, she knew that she didn't trust her uncle to not grope her. She wanted to move his hand away but she waited. She glanced across at Sara, who was watching tv.

To her surprise, her uncle didn't try anything. His hand remained fixed on her stomach and didn't move. She began to relax again. She spread her legs, knowing that her brother, sitting opposite, would get a good view of her bare pussy. She looked at him, and he smiled. After a while, she lifted her right leg and bent it, so that her foot was on the couch. Not long after she hooked her left leg over her uncle's right leg. The bottom of her dress was riding high and her legs were spread wide, giving Jack a great view, but all her uncle could see were her smooth long legs. All this time his hand stayed on her stomach.Jack caught her attention and nodded in the direction of Aunt Sara, who had fallen asleep.

"Looks like Sara has had enough for today," smiled Laura, prodding her uncle's thigh to get his attention.

Mike stood up, shook his wife awake and led her upstairs. He helped her out of her clothes then lay her in the bed. At the same time Laura had gone to her room to change for bed. Her uncle hadn't tried anything yet and she was beginning to doubt her misgivings about him. She decided to test him, as Megan had said. She put on a small yellow crop top, emblazoned with 1990 in big black print. Then she put on a pair of lacy white panties. Nothing else. She heard Mike go back downstairs and waited five minutes before going down. Her heart was racing and to her surprise she realized she was feeling horny.

She entered the living room. She felt two pairs of male eyes watching her as she crossed the room. Her grandfather was asleep in his armchair. She sat next to her uncle on the couch and cuddled up against him.

"You used to do that when you were little," Mike said.

"I used to call you my little princess, do you remember?" he added.

Moments later his arm wrapped around her and his hand settled back down on her stomach. Still he did nothing to worry her. Jack was watching this and knew what his sister was doing. He wondered if Mike wouldn't try anything while Jack was in the room so he stood up.

"I'm just going to have a quick shower. This heat makes me feel so sticky. See you in ten," he announced.

Laura smiled at her brother, her mind clicking with his thoughts. Just them and George in the room, but her grandfather was fast asleep. Soon after Jack left, Mike stood up to go to the kitchen, clutching his empty wine glass.

"Want some?" he asked his niece, shaking his glass.

"No thanks. Don't like it," she replied.

"One day you will," he smiled.

As soon as he left the room she edged up the bottom of her crop top, so it was just below the swelling of her breasts. She also nudged the top of her panties down a bit, so there was a large area of bare, tanned flesh between her top and her panties. Mike came back in and sat down, wrapping her arm back around her. He offered her a sip of wine.

"Go on, try it. It's a good wine," he teased her.

Surprising him she took a gulp. Still his hand remained on her stomach. The minutes passed and Jack returned from his shower. He raised his eyebrows at his sister but she shook her head gently. The movie finished and Laura stood up and went to bed. Mike and Jack woke up George and led him up to his bed. In her bed Laura felt strangely disappointed that her uncle hadn't tried anything. She felt horny and masturbated, trying to imagine her uncle's hands roaming all over her naked body.

On Sunday morning Mike and Sara joined Jack and Laura on the beach. The men led the way, both wearing shorts. At her uncle's request Laura, in a light blue bikini, waited for Sara to get ready. Sara appeared, also wearing a bikini. The two of them walked in mostly silence to the beach. They both sunbathed while the men played in the sea and with a football. Laura lay on her back watching them, in between reading a book.

When the boys had finally had enough of their games they came to sit down. Jack sat at the far side, nearest Sara, while Mike sat nearest to his niece, near the bag containing food and drink.

"Anyone want anything to eat yet?" he asked, opening a bottle of water.

"What food did you bring?" asked Jack.

"Just some bits and pieces."

"I made a load of cup cakes the other day. We could have those," suggested Laura.

After a short discussion Mike went back to the house to fetch the cakes. In his absence Sara rolled onto her stomach and settled down to sleep for a bit. Laura also rolled onto her stomach, and removed her bikini top. Jack looked at her and smiled.

"What?" she mouthed silently to him, smiling.

Jack made pretend stabbing actions over Sara's back while she was sleeping and they both laughed.

Mike returned with the cakes. He and Jack had one each while Laura read her book. Jack eventually fell asleep, leaving Laura and her uncle reading. After a while Mike sat up.

"Drink, Laura?" he asked his niece.

She nodded, putting her book down and sitting up slightly. Not enough to expose her breasts. They were still pressing against the towel she was lying on. She took the cup her uncle passed her and drank from it, then settled back to read. He offered her another drink a while later and again she sat up, being careful not to expose her titties. A little while on, as they were both lying reading she casually stretched her left arm out to get her uncle's attention. Not really bothering to notice where she touched him, her hand landed against his shorts.

"Huh?" Mike muttered.

"Can I have a cake now please?" she asked him.

He sat up and passed her a cake. She lifted her body slightly to eat it but found it awkward. So she edged herself up a bit more and felt her nipples coming off the towel. Ignoring this, and knowing that if he was looking at the right angle, Mike would be able to see her tits, she ate the cake. Then she lay back down again. Her heard was thumping as she thought about the idea of him seeing her breasts. She was feeling naughty, as she glanced over to her brother and aunt, who were both sleeping.

A few minutes later she asked for another one. She put her book down and lifted up to take the cake Mike offered her. This time she lifted up a bit higher, knowing that her tits would be visible. She ate it.

"Mmm delicious! Even if I do say so myself," she joked.

"You like baking?" her uncle asked her.

She nodded and turned slightly towards him, exposing her boobies to him a bit more.

"I always have done. Mum taught me. I've made loads since I've been here. Granddad loves them," she smiled, acting innocent and talking about cakes while her tits were exposed.

At that moment Sara stirred. She sat up, and Laura flopped down instantly. Sara had a drink and a couple of cakes, noticing but choosing to ignore that Laura was topless. Jack also woke up and he and Mike went off to play in the sea.

Laura sat up, exposing her breasts, and put her top back on. After a while they went in for lunch, before visiting Nan in hospital. Mike and Sara went for a drink in the village that evening, and feeling tired, Laura went to bed early. Nothing happened on Monday until the evening. Megan knocked on the front door. Mike answered and invited her in. She was wearing a very short skirt and a bikini top. Laura and Jack stood up and the three of them went down to the beach. Mike watched them leave.

"Where do they go, dad?" Mike asked George.

"To the beach, at the end of the dunes. To watch the sunset."

"Sounds lovely. I might go as well. I used to like that when I was younger."

"I think they have a few beers and chat," George added.

"Stay with me baby," Sara whined, so Mike sat back down.

On the beach Jack, Laura and Megan were naked. The two girls were sucking his cock as he rubbed their titties. He came, shooting his sperm across both their faces, and then they licked it off each other and swallowed. When they got back indoors Laura had a shower before sitting next to her uncle on the couch, wearing a white t shirt, that just covered her ass. As usual she seemed to have forgotten to put any underwear on.

Megan had asked her about her uncle and she had told her that nothing had happened.

She sat down and leaned against Mike. He wrapped his arm around her and placed his hand on her stomach. They stayed like this for a while, before Sara stood up and went to bed. Mike went after her, promising he would be back down shortly. In his absence Laura lay on the couch, her feet at one end, her head at the other. Mike came back in, looking around.

"Where can I sit?" he asked, looking amused.

Laura lifted her feet and he sat at the far end. She put her feet back down, resting on his lap. She was careful to keep her legs together, so she didn't give him a view up her shirt. Gradually Mike shifted up towards the center of the couch, so that the back of her knees were on his lap. He rested his hands on her legs and they sat this way for a while. Finally his left hand reached across and rested on her stomach. Laura was aware that the shirt only just covered her ass and pussy and was feeling quite worried that she might expose herself. Again though his hand didn't move and she began to relax.

Feeling bolder she decided to test him. She pretended to fall asleep, and after a while, as she faked sleep, she edged her legs up a bit, so her shirt rose up. She did this for a while, wriggling about. She peeked out of the corner of her eye. Her uncle was still watching tv, his hand on her stomach, but her shirt had moved up enough to expose her pussy lips slightly. She closed her eyes again. Mike suddenly stood up and went to the kitchen. She sat up and shifted round, folding her legs under herself. Mike came back in and announced that he was going to bed. Again feeling slightly disappointed Laura masturbated in her room that night.

Tuesday morning and Mike and Sara were going home later. After her grandfather had brought her a cup of coffee Laura lay in bed, still naked. She felt down between her legs and decided it was time to have a quick shave. She could feel a bit of pubic hair growing back. She felt her armpits to and decided it wouldn't do any harm to make them smoother.

"I've been letting myself go a bit," she smiled to herself.

She jumped out of bed and put on a pair of baggy gray sweatpants. She looked for a shirt but decided to just go to the bathroom as she was. No one but granddad would be up yet. She went to the bathroom, stripped off the sweatpants and had a quick shave. Then she put the pants back on and began to quickly remove any hint of hair growing in her armpits. She was disturbed by the bathroom door handle turning. Then a knock when whoever it was discovered the door was locked.

"I need the toilet," whispered Mike.

"I won't be long. Can you wait?" she replied.

"Oh Laura, hi. Don't be long."

She continued her business. Then another knock.

"Laura I'm getting desperate. Will you be long?" her uncle asked again.

Again she asked him to wait. Every couple of minutes this exchange was repeated. Laura was hoping to finish and get back to her bedroom, knowing that she had no means to cover her breasts. Eventually though she had enough of his pleading. Taking a deep breath she reached for the door.

"Just come in and quick and do your pee," she said, unlocking the door and returning to the basin.

Uncle Mike opened the door and stepped forward. He took one look at his topless niece standing by the basin with one arm up in the air and stopped.

"Oh shit sorry Laura."

"Just shut the door quick before anyone sees us!" she told him.

He stepped in and stood over the toilet bowl,pulling out his penis to pee. He glanced to the side to his niece as she continued to shave her armpit, totally ignoring him. He took in the sight of her beautiful pert young breasts, her erect nipples and silky smooth skin. He finished peeing and shook his cock a couple of times, before stuffing it back in his shorts.

"Finished? Happy now?" Laura smiled.

"Yes thanks. I err I need to wash my hands now."

She stood back from the basin, allowing him access. When he finished he shook his hands, sending cold drops of water onto her chest.

"Ow you pig! You did that on purpose!" she exclaimed.

He just laughed and walked to the door, looking back at her breasts just one more time. As he opened the bathroom door he saw his wife standing in the bedroom doorway, staring at him.

"Did you pee? Who was in there? I heard you calling out," asked Sara.

"Yes thanks. Oh it was just Laura. She let me in. Ready for breakfast darling?" he replied, changing the subject.

After breakfast Mike and Sara packed their things into their car and left for home. Laura and Jack helped their grandfather tidy up, then rested for a while, reading. It was raining outside but despite this they decided to go for a walk. They walked along the beach, past Megan's house, a part of the beach they hadn't explored before. There were some rocks, that they climbed on, just as if they were two children. Then they turned around and walked back. They stopped when they heard loud banging and knocking noises coming from a garage just behind Megan's house. Curious they decided to take a look.

In the garage they found Megan and her father Henry clearing out piles of boxes and tools.

"Hi! Just having a clear out. Probably going to paint this old garage," Megan said cheerfully when she saw her friends.

"Oh we wondered what the noise was," replied Jack.

"What are you two doing?" Megan continued.

"Oh we just went for a walk. Our uncle and aunt have gone home so we were a bit bored," answered Laura.

"Weather's not so good. That's why we thought we'd make a start on this garage," added Henry.

"Do you want any help?"

"No it's ok. Thanks for asking though," replied Henry.

The two siblings walked on back to their grandfather's house. That afternoon the three of them went to the hospital to visit Nan, then George took them to a restaurant as a treat. When they got home Laura was surprisingly tired and went to bed early, in her own bed.

When Jack came up to bed early he was surprised to see his sister was not in his bed. He went to her room but when he looked in she was fast asleep, so he left her in peace. The next morning, when her grandfather brought her a cup of coffee, Laura woke up with a terrible headache and felt very lethargic. She stayed in that morning, sleeping for most of it.

Without his sister Jack was a bit unsure what to do. It was a much hotter day, but still cloudy.

"They reckon another bad storm is on the way," George informed his grandson.

"Do you want to go birdwatching, Granddad?"

"No I think it's best if one of us stays to keep an eye on your sister. Make sure she's ok. You go if you want."

Jack sat around for a while, reading. He decided to go to see if Megan fancied a walk. He went the long way, around the dunes and the beach. By the time he got to her house he was dripping in sweat. He knocked on the front door but there was no answer. Remembering they were in the garage out back yesterday he went around the side of the house. As he did so he heard noises coming from the garage. Not the banging and crashing noises from yesterday, but different noises. Moaning noises.

He was about to call out but he hesitated, instead creeping along so he could peek in the garage. As soon as he could see inside he stopped, his mouth falling open in disbelief.

Megan was naked. So was her father, who was sitting on an old wooden crate. Megan was bouncing up and down on her father's lap, with his erect cock apparently thrust inside her vagina. They were both moaning, their clothes in a muddle on the garage floor.

"Oh yes that's it oh yes that's good cum for me baby," moaned Henry.

"Oh daddy that feels so good oh yes oh yes oh god please daddy please," his daughter sighed.

"Mmmm baby you're such a good girl oh baby."

"Daddy oh god I love you so much I love you doing this to me."

"Megan oh my sweet Megan I love you too I want to make you scream with pleasure."

"Oh daddy you always do oh god I'm cumming oh god!"

"MMMMMNNNNGGG!! GONNA CUM!!"

"OH DADDY OH YES OH YES OOOOOOHHHHHHH!!"

Megan's moans turned to screams as their thrusts got harder and faster. Jack crouched down on his knees, partly through a desire to remain hidden, partly because he was so shocked he thought he might fall over.

"MEGAN!! OH GOD OH GOD OH YES!!"

"OH DADDY!! OOOOHHHHH!! OH YES MMMMNNNNGGGG OH YES OOOHHHHH!!"

Jack was aware that his own cock was throbbing as he watched his new friend fuck her father. Megan rubbed her pussy with one hand as her dad continued to pump her. Jack slipped his hand into his shorts and began to rub his cock.

Finally Megan and her father both came. They remained sitting on the box for a few minutes after, Megan still on his lap. Eventually she sat up and stood in front of her dad. Henry stood up and they cuddled briefly.

"Right I suppose we had better get on with this," he said.

Jack stopped his own masturbation, fearful of being discovered. It occurred to him that he shouldn't be the one to worry but he still wanted to get away. Megan and Henry made no attempt to dress as they looked around the garage at the mess.

"Do you want a drink daddy. That was hot and I'm thirsty!"

Henry nodded and slapped his daughter's bare ass as she headed towards the open garage door. Jack hid behind a discarded old tractor engine as she walked towards the kitchen.As soon as she had disappeared from sight Jack edged along the side of the garage and over the wall. He then crawled along through the sand dunes until he felt sure he wouldn't be seen. He stumbled down onto the beach and sat thinking about what he had seen. Feeling horny he stripped naked and jacked off, the picture of Megan and her father clear in his mind. Finally he walked back to his grandfather's house.

"I must tell Laura," he thought to himself.

Jack ran back to the house and found Laura sitting at the kitchen table reading a book.

"Are you feeling better now? " he asked.

"A bit thanks."

"Well I saw something that will cheer you up "

To make sure their grandfather couldn't hear them they went up to Jack's room where he told his sister exactly what he had seen. Every detail. By the time he had finished she had forgotten all about her headache.

"I knew there was something weird about their life," she muttered.

"That explains why she was so cool about us..you know..." smiled Jack.

"Do you think we should say anything? You know, like let on that we know? " asked Laura.

"Mmmmm, I don't know. Maybe not. If she wants us to know she would tell us."

"Guess so. I mean we're really close with her but she hasn't told us that side of her life so maybe it's just a secret too far," pondered Laura.

They sat about reading the rest of the day, until Megan came around that evening. It was raining outside so they all just watched a movie. Noticing that their grandfather had fallen asleep on his armchair, Laura suggested that they could go upstairs. Jack and his sister led Megan to Jack's room where they all stripped naked. Jack lay on the bed and Megan straddled him, lowering her cunt to hus cock. Laura sat on her brother's face and he began to lick her pussy. They swapped positions and ended up with Jack stroking his cock as the two girls kneeled in front of him.

Meanwhile downstairs George had woken up. Noticing he was on his own he assumed his grandchildren had gone to bed. He turned off the tv and went upstairs. He heard moaning from Jack's room and smiled to himself as he pictured his grandchildren having sex again. However he heard a third voice calling out.

"I know that voice. Surely not..." he thought to himself.

George crept along the hallway and carefully peered in through Jack's doorway, just in time to see hus grandson shoot a load of sperm into the faces of Laura and Megan. The old man smiled, shaking his head as he walked back to his own room, recalling some of his sexual escapades when he had been young.

Megan dressed and said goodbye to her friends before going back home to her father. He too was asleep. She once again stripped naked, and climbed into bed beside him, as she did every night. She was careful not to wake him, knowing that if she did, he would almost certainly want sex, and right now she was too sore from fucking Jack and being licked by Laura.

The next morning George brought coffee to his grandchildren, finding them asleep still. Gently he reached down to touch Laura's bare nipple. He squeezed it a few times. Laura woke up but didn't respond, instead just enjoying feeling her tit being pleasured. George stopped and left the room. Laura opened her eyes just as her grandfather walked out the door, realizing it had been him and not her brother who had been touching her. She climbed out of bed and walked naked down the hallway to her grandfather's bedroom door. She pushed it open to see George on his bed,with his hand stroking his erect cock."Granddad!" she exclaimed.

George looked up to see his naked granddaughter stating at him.

"Sorry Laura I didn't mean to..."

"It's fine granddad. I like it..." she said, walking towards his bed.

She climbed on the bed and pushed his hand aside, taking his cock in her own hand.

"Laura this is so wrong," he moaned.

"I don't think we should worry about that. You only live once.I have sex with my brother so I am not the right person to talk about right and wrong!" she laughed.

George laughed nervously at his granddaughter's lack of morals.

"I should warn you I take ages to cum these days," he added.

"Really? That's a good thing!" laughed Laura as she stopped Jacking him off and climbed onto her grandfather's lap.

She lowered her pussy onto the tip of his cock and began to fuck him. He wasn't wrong. Laura thrust her cunt against her grandfather's cock for nearly twenty minutes, cumming several times.

Jack had woken up to find himself alone in bed. He heard voices from down the hall and climbed out of bed. As he walked out his room he heard the unmistakable sound of his little sister moaning with pleasure. He assumed at first she was masturbating but he thought it was unusually loud for masturbation. As he approached his grandfather's room he realized she was in there. He pushed open the door to see Laura fucking their grandfather.

"FUCK!!" he exclaimed.

"Jack!" Laura cried out.

"That is so hot!" Jack laughed, beginning to stroke his hardening cock.

"Help me out here big brother," laughed Laura.

"Huh?"

"I've been doing this for half an hour. I'm shattered and I've already cum five times!" she explained.

Jack climbed on the bed. Laura got up from her grandfather and began to suck her brother's cock. While she did this George began to jack himself off again. To his amazement his grandson reached across and began to stroke his cock. Laura also watched in shock as her brother gave their grandfather a handjob. Finally George came, shooting sperm out across the bed as Jack filled his sister's mouth with cum. The three of them then lay down to rest.

Laura was so tired after fucking her grandfather to go out that day. She stayed behind while Jack and George went to visit Nan.

For the next ten days Jack and Laura had sex whenever they got the chance, either just the two of them or with Megan. They didn't ask their grandfather again and he made no attempt to join them, even when they made no secret of their activities.

On the last morning,a Saturday, they lay in bed together, having just fucked.

"This has been a summer I'll never forget," joked Jack.

"Are we going to carry on doing this when we get home?" asked his sister.

"I want to."

"So do I," Laura smiled.

A car pulled into the driveway.

"Mum and dad. We'd better get dressed."
