The Holiday House

"It's so nice to have you kids with us for a change," said Mrs Roberts. "Can't remember the last time we vacationed together, or even had dinner around a table together."

Keith shrugged. "Helps that Uncle Bill's holiday house is a bit closer for us."

Summer nodded. "Also that it's disgustingly luxurious. I can only assume dear old Uncle Bill owns an illegal diamond mine we didn't know about."

"Did you see the master bed?" asked Keith. "I reckon you could fit a family of six on that."

"Did you watch that documentary too?" asked their dad.

"Yes!" said Keith. "Guess we should be grateful we live in a time where we get our own bedrooms."

"Still plenty of cultures that do communal sleeping today," said Summer.

"Well in this one, your mother and I get the master bed to ourselves," said their dad.

"As long as there isn't a thunder storm," said their mum.

"What?" asked Summer.

Their dad chuckled. "Maybe you're too young to remember, but when there was a storm, Keith used to get in bed with us and snuggle up to your mother."

"Hey, thunder storms are no joke when you're a kid," said Keith, a slight smile on his lips.

"Wow, you really were a mummy's boy, weren't you?" said Summer.

Their mum smiled. "He's still my little snuggle bunny, aren't you Keith?"

Keith shrugged and smiled back at her. "You made me feel safe." He turned towards Summer. "Is it that much different from you sitting on Dad's lap?"

"I suppose," said Summer. "I might be a bit big for that now."

"You'll always be my little girl," said their dad.

"Don't worry," said Keith with a grin, "I think the weather forecast is relatively clear during our vacation. Besides, wouldn't want to cramp your style."

"Not much style to cramp, these days," said their mum.

"Right," said Keith. "Well on that somewhat awkward note..." and he stood up, cleared his plate away, and loaded it into the dishwasher. "I might go flick on the TV."

He headed into the lounge room, flicked on a movie, settled into the armchair and started watching. His parents soon joined him. "Oh," said his mum, "I always wanted to see this one." The two of them settled into the couch.

It was when Summer came and joined them that the main issue with the lounge room presented itself. "You'd think a house with five bedrooms, three of them with en suites, would have a bit more seating around the TV," she said.

Keith shrugged. "You could always grab one of the chairs from the dining room."

She shook her head with a grin. "Dining room chairs, on this carpet? Barbaric." She plonked herself down on Keith's lap.

"Oof," said Keith. "C'mon, gotta give me some warning before you do something like that."

She grinned. "Sneak attack wouldn't be very effective if I gave you a heads up." She leaned back against him and they continued watching.

After a few minutes, Summer shifted in Keith's lap. "Do you mind?" he asked.

"Oh shush, I'm just trying to get comfy."

"Both of you shush," said their mother.

They both shushed, but Summer did not stop moving. Keith leaned forward and hissed in her ear, "C'mon, find a spot and settle."

She muttered under her breath, "Not my fault you have such an uncomfortable lap."

"Never asked you to sit in it," he said.

"Come on, enough!" said their father.

So they sat in relative silence and continued watching the movie. And Summer squirmed in Keith's lap again, and he poked her in the ribs, and she squirmed even more, recoiling from the poke.

Their father stood up. "I just realised what we're missing."

"Oh?" said Keith.

"Popcorn! I'm going to go make some. Honey, want to give me a hand? I don't know where everything is in this kitchen."

"Well, I don't want to miss the film," said their mother. Keith picked up the remote and paused the movie. "Oh, thanks dear. All right sure, I'll help." So their parents both got up and went to the kitchen.

"All right seriously," said Keith, "you gotta stop moving so much."

"What, like this?" She thrust her butt backwards and started grinding on him.

"Come on, are you for real right now?"

"Oh stop your complaining, it's not like I'm that heavy."

"That is absolutely not the concern."

"Then what... oh." She looked down and lifted her skirt out of the way; his erection was forming a large bulge in his pants. "Come on, you can't control yourself?"

"I did tell you to knock it off."

"Maybe this is an opportunity for you to learn some self control." She backed her butt into his chest and continued to grind.

"Really? Even after you've seen my whole situation?"

She giggled. "Really seems like not my problem."

"Well, we'll see," he said. He reached past the hem of her skirt, undid his fly and pulled out his erection.

"What the fuck?"

"Looks like it's your problem as well, now. Gonna stop messing with me?"

"What's her problem now?" asked their dad from behind them.

Summer let out an involuntary squeak, slid forward to cover his erection and smoothed down her skirt. "Oh nothing, it's just a private joke."

Their parents sat back down on the couch, and their mum offered them the bowl of popcorn.

"No thanks," said Keith.

"Watching my diet," said Summer.

Their dad shrugged. "More for us."

There was a moment of awkward silence, then, "Keith?" asked their mum.

"Yeah?"

"Can you start the movie again?"

"Oh, of course. Forgot I had the..." he picked up the remote, and unpaused the movie.

They'd only been watching for ten more minutes when Summer shifted in his lap again. He poked her gently in the ribs; she giggled and shrugged, but kept moving. He raised an eyebrow, then leaned forward and whispered in her ear, "Really?" She grinned and shrugged. "Remember, you started this," he said. He started to gently pelvic thrust, his erection rubbing against her panties. She gasped, paused for a moment, then kept grinding on him.

For the next few minutes, Keith and Summer quietly dry humped each other, while their parents watched TV, oblivious, about a metre away. The more she continued to grind her butt on him, the harder he got, and as he continued to thrust against her, she started to get wetter. What had started as a way for Summer to mess with Keith was becoming something else. Summer leaned forward slightly; during the grinding and thrusting, the crotch of her panties had been displaced to one side, and Keith's hard member slid up and nestled alongside her entrance. They both froze.

They tried not to move for a few minutes, and to instead watch the movie. Then Keith twitched involuntarily, and Summer shivered. They settled down again, then Summer started slowly, subtly grinding along his length. They stayed like that for the rest of the movie, Keith's erection nestled against her entrance while she slowly, imperceptibly, moved herself up and down it.

And then the credits started rolling.

"Right, guess that's it," said their dad. "I'm off to bed."

"Me too," said their mum.

"I think I'll wait through the credits," said Keith.

"Oh, this is a bit of an older film," said their dad. "They didn't really do the end credits scene back then."

Summer shrugged. "You never know."

Their parents shrugged and headed off towards bed.

Keith breathed out. He hadn't realised until now that he'd been holding his breath. "I can't believe you went this far trying to mess with me."

Summer shook her head. "I'm not the one who got their dick out."

"Oh, you've got a dick now?"

She chuckled, and the action moved her against Keith's erection again. "We should probably stop, though. This has gotten a bit out of hand."

He nodded. "Yeah, you should get off me."

"Yeah," she said. "Yeah, I will. Just give me a moment to collect myself." She took some deep breaths.

"Right," he said. "Yeah, I've got to take a moment too."

She took more deep breaths, and started to move, with the breaths, against his erection. He put his hands on her hips and started to lift her up and down. "We'll just... just a few minutes maybe," she said.

"Right," he said. "No need to move right away."

She leaned back against his chest, put her feet up on the armchair, and started sliding up and down his chest. He kept a firm grip on her hips and helped the up down sliding motion. As she slid up, she slid almost clear of his erection, and instead of the length, its tip nestled right at her entrance. "Ooh," she said. "That probably wouldn't be a good idea."

"Probably not."

"How about if..." she paused. "Just a... just a tiny bit." She slid down so the head was just inside her. "Just that far."

"Yeah," he said. "Yeah, as long as we don't go... don't go any further."

She pushed herself just clear, and sunk down again. He moaned softly, then moved one of his hands from her hip to her stomach. She looked down at it as he slowly moved his hand up her torso, and grabbed onto a breast, over her shirt. She leaned to one side and turned to face him. "Would it be weird if you kissed me, just a bit?"

He leaned forward, then turned and kissed her on the lips. "It's a little bit weird," he said.

She nodded. "Sorry."

He kissed her again. "I didn't say that was bad."

She smiled, kissed him back, pushed herself up a little bit off of him, and then sunk all the way down. "Whoops."

He gasped. "Wow. That's a lot." He grabbed her by the hips, pulled her off of him, and then thrust himself all the way inside her again.

"Yeah," she said. "We really shouldn't." She raised herself up and down again. And up, and down, and the two of them were fucking.

"Oh my god," he said.

"Fuuuuck," she said. "Wait." She pushed herself all the way off of him and climbed out of the armchair. He breathed out; she was right, it was probably best they stop. But she turned to face him and climbed back on.

"Oh," he said. "I thought..."

"Shut up," she said, putting a finger to his lips. He smiled. He grabbed her butt, one hand on each cheek, and assisted her as she bounced up and down on him, both of them breathing heavily but making no other noise.

After the previous couple of hours of teasing each other, they didn't last much longer. He'd been thrusting inside her for a couple of minutes when she started shuddering. "Oh my god," she moaned. "Yes. Yeeees. Holy shit."

He wasn't far behind her. "I think I'm about to... where do I...?"

"It's all right," she said. "I'm safe. Give it all to me." He thrust inside her, wrapped his arms around her, and erupted.

"Can I kiss you again?" he asked. She nodded and leaned down towards him, and he leaned forward and kissed her. They sat like that for a while, him still inside her, her straddling him, their lips and tongues playing with each other's. Then she detached her mouth from his, got up from on top of him, readjusted her panties, smoothed her skirt down and sat on the sofa where their parents had been only minutes before. They both sat in silence for the next several minutes.

She was the first to break the silence. "Oh my god, I can't believe we just did that."

"Yeah," he said. "That was pretty wild. I think we got a bit carried away there."

She nodded. "It was pretty fucked up. We may be the worst siblings ever."

"Mmmm," he said. There was an awkward pause, and then he turned his head to face her and said, "It was pretty hot, though."

She let out a breath she hadn't realised until now she'd been holding. "Oh my god. Yes. It was the hottest thing I've ever experienced."

"Thank god it's not just me," he said. "I think having Mum and Dad like a metre away made it even hotter. Imagine if they'd caught us!"

"Oh my god, they would completely disown us. Who do you think would be madder at us?" she asked.

He shrugged. "I don't think Mum could stay mad at me for that long."

She chuckled. "Bet you wished it was Mum you were fucking."

"Steady on," he said. Then he thought for a moment. "But also, sure why not, I just fucked you, why not fuck Mum too?"

She raised an eyebrow. "Wow you really are a Mummy's boy."

"And I bet Daddy's little princess would've preferred to sit on his lap and ride his dick."

She paused for a moment. "Hmmm. That'd be pretty fucked up too."

"Not hearing a 'no', though."

She chuckled. "If you'd asked me this morning I would've said you were sick, but this morning I hadn't fucked my brother. I guess committing a felony gives you a different perspective on life sometimes."

"Huh," he said. "Is it actually a felony?"

"Well it's definitely a crime," she said. "I'm not that familiar with the criminal code, maybe it's not a felony, maybe it's just a misdemeanour. I don't really know the difference. Don't worry, though, I promise not to turn you in."

He chuckled. "Do you think they'd let us share a jail cell?"

She laughed and shook her head. "We should go clean up and get to bed."

He nodded. "Probably a good idea." He tucked his penis back into his pants, did his fly back up and stood up. He paused before he headed to his room. "You'd totally love to fuck Dad, though, right?"

She laughed. "Not as much as you want to fuck Mum, but yeah. Fuck yeah, why not."

He smiled. "Thought so." Then he left to go shower and sleep.

Once Keith was awake next morning, he slipped into Summer's room. She was still in bed. He gently shook her awake.

"Hmm?" she said.

"Just wanted to touch base, make sure I didn't dream last night and that... that we're still cool."

She smiled. "Not a dream. We basically fucked in front of Mum and Dad."

"Huh," he said. "Pretty eventful for a first night of vacation. And we're still cool?"

She smiled, got out from under the covers and sat up on the side of the bed. "We're cool. Got a good morning kiss for your sister?"

He chuckled, leaned forward and kissed her on the lips. "I was gonna ask if last night was a one time thing."

She gave a sly grin. "I hope not." She paused. "But not in front of Mum and Dad again. That was hot as hell, but we can't risk them catching us." She smiled. "But who knows, maybe we'll be too busy fucking Mum and Dad to bother with each other."

He laughed. "Wishful thinking for both of us, I fear."

"Alas," she said. "You'll have to do, I guess."

He shook his head, kissed her again, then went to the door. "I'm gonna go have breakfast."

After breakfast, (bacon and eggs for Keith and Summer, yoghurt for Mum, porridge for Dad) the four of them went to the beach. Well, they went out the back door of Uncle Bill's holiday house, which opened onto sand.

"I can't believe Uncle Bill has his own private beach," said Keith.

"Yeah," said their dad. "He's done well for himself."

"Well," said their mum, "no kids."

"Ah, so if it weren't for me and Summer, the two of you would be living like this as well?" said Keith.

"Well, there's also that illegal diamond mine of his," said their mum.

"Knew it!" said Summer.

"No, he's not a diamond baron or whatever," said their dad. "He's..." he paused. "I'm not really sure what he does."

There saw some wicker lawn furniture under a pavilion at the edge of the beach, where it met the grass. They sat down and started applying sunscreen. Summer quickly finished her arms, legs and her front, then walked over to their father. "Dad, can you do my back?"

"Uh, sure thing princess. Just let me finish my legs."

"Oh, I can do that for you while you do my back," she said. She stood in front of him, gently parted his legs, then sat down on his chair in front of him, her back brushing his chest. She leaned forward, and started rubbing sunscreen on his legs.

"Right," he said. "Good idea. Very efficient." He squirted sunscreen on his hands and started massaging it into her back.

Keith grinned to himself and shook his head. Out of the corner of his eye he could see Summer was doing her best, as she bent forward and massaged sunscreen into their father's legs, to push her butt back into his groin. Their father steadfastly refused to acknowledge this was happening, and continued applying sunscreen. He quickly finished, although Summer was still applying sunscreen to his legs.

She paused. "Daddy, can you apply it under the strap of my bikini top, too?"

"What?"

"Just at the back!" she quickly said. "Just in case the strap shifts at all when I'm swimming or whatever."

"All right," he said, "sure." He slid his fingertips under the strap of her bikini and finished applying the sunscreen. She had also finished on her legs.

She stood up. "Scoot forward," she said, "I'll do your back."

"Right, sure," he said. He scooted forward in the seat, and she climbed in behind him. She leaned forward, squashing her breasts against his back, and held out a hand. He squirted some sunscreen into it, and she leaned back and started applying it to his back.

Before long she'd finished. She climbed out from behind him again, then reached out to him to help him up. "Come on Daddy," she said, "come into the waves with me!"

He glanced towards his wife and his son, but quickly followed Summer out onto the beach.

Mrs Roberts sighed. She had finished applying sunscreen to the areas she could easily reach, and was awkwardly trying to reach her back. Keith chuckled. "Come here, Mum," he said. "I'll get that for you."

She stood up and flashed him a grateful smile. "Thanks, honey. You sure you don't mind doing this for me?"

He nodded and, arms outstretched, beckoned her to come sit in front of him. "Can't have you burning, can I?"

She walked over to him, then stood awkwardly in front of him. "Where should I...?"

"Just sit on my lap," he said.

"Are you sure? I'm not as light as Summer."

He patted his lap invitingly. "I'll be fine."

She turned and sat on his lap, then swung one leg over so she had one foot on either side. He squeezed sunscreen onto his hands and started massaging it into her back. As he came close to finishing, she sighed again. "I shouldn't have worn a bikini."

"Don't worry about it," he said. "We'll just be careful with reapplying sunscreen to make sure you don't get burnt."

"No," she said, "I mean, I don't have the figure for it."

"What?"

"Not like Summer."

He wrapped his arms around her waist and pulled her back into him. "Mum," he said, "you're gorgeous, and you look fantastic in that bikini."

"Well, I wish someone would tell your father that."

He shook his head. "He's probably just focussed on other things."

"Yeah," she said, "like younger and hotter women. Like..." she stopped, but Keith knew who she meant. Like Summer.

"Mum," said Keith, "younger doesn't always mean hotter. Sure, men will sometimes get distracted by something shiny and new because we're capable of being idiots, but that doesn't mean Dad doesn't realise how amazing you are."

She sighed again. "Thanks honey. Is it all right if we stay here for a bit though, instead of rushing straight into the surf?"

"Sure thing, Mum," he said. He leaned over her shoulder and turned to kiss her cheek, but she turned at the same time, and his lips met hers in an awkward peck.

"Oh," she said. "Sorry, didn't mean for that."

He laughed. "Sorry, my fault. Was just trying to give you a peck on the cheek. Still, some families greet each other that way, so it's not that weird, right?" He leaned forward and planted another kiss on her lips.

She giggled. "It's a little weird, but kind of nice." She leaned forward and gave him another peck. He hesitated a moment, and then leaned forward and gave her a longer kiss, lingering on her lips before he pulled back. "Phew," she said, her face flushed. "Maybe that's a bit much."

He smiled, leaned back in the chair, and pulled her down with him, his arms still wrapped around her waist. "Just trying to show you it's not that weird."

They rested like that for a while, his arms circling her waist. Keith could feel himself starting to harden slightly, and he tried to let his mind wander elsewhere. Somewhere other than the gorgeous woman in his arms whose butt was not far from the part of him that was slowly hardening in response.
