"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."
