One Night Only

"Hey Bro, I need you to do me a favour."

"Yeah, what's that?"

"Well, you remember that Carly and I are heading out of town, right?"

"Yeah, rings a bell."

"Well, I was hoping you might be able to help Jessica out a bit while we're away. The damned girl still hasn't got around to getting her license, so she can't drive herself anywhere, but she still has to get to all her commitments. She can bus for a lot of them, but sometimes it just doesn't work out well."

"So like, I'm gonna play Uber?" Mark asked, with a laugh.

"Well, hopefully not quite at her beck and call to that extent, but yeah, that's the gist of it."

"Yeah, I'll help out."

"Thanks Mark, it's very much appreciated."

"I'll give you the bill when you get back. How long you away for again?"

"A month, including the weekends at either end. I think she'll mostly need a ride to volleyball games. Sadly, they're early Saturday mornings."

"Early? Like how early?"

"She has to be there by eight."

"Fuck, maybe I should have thought this through more before agreeing so readily."

"Well, I heard a yes, so that's good enough for me," Jack teased his younger brother.

"Yeah yeah, I'll survive. Might have to hold back on the Friday night beers a little though."

--- +++ ---

"Hey Uncle Mark, just checking that you're good to pick me up to take me to volleyball tomorrow morning?"

"Yeah, that'll be fine Jess," he replied. "Seven-thirty at yours work for you?"

"Yeah, that will be great. See you then."

--- +++ ---

Mark grabbed his coffee and stumbled out the door. He couldn't remember the last time he'd been up so early on a weekend. He'd held back on his usual Friday night antics, but he was still hurting a little.

He pulled up out the front of his brother's place, and resisted the instinct to toot the horn to announce his arrival. He was pretty sure the neighbours wouldn't be impressed, so he dragged his ass out of the car and went and rang the doorbell, instead.

"Coming!" he heard Jess call out. He waited a few moments until he heard footsteps and then stood back while the door opened and Jess stepped through it, pulling it closed behind her.

"Hey Uncle Mark, I hope it's not too early for you."

"It is definitely too early for me," he replied with a laugh, shaking his head as he walked back to his truck.

Jess followed him, but went to the passenger side, climbing up into the cab to join him.

"You don't really strike me as the volleyball type, you know?" he observed, as he started the truck.

"Why? Because I'm a short ass short-ass?"

"Well, now that you mention it, yes. Aren't volleyballers supposed to be tall?"

"I'm a setter, Uncle Mark; I get the ball up where the hitters can smash it over the net."

"Right, fair enough then. Can't say I've ever really paid attention to the game myself."

"You should come in and watch then," Jess suggested.

"Depends on whether it's likely to be better than grabbing some extra sleep in the truck."

"What? You think sleeping would be better than watching hot girls bounce around a volleyball court? You know what we wear, right?" Jess teased.

"Girls half my age that I certainly shouldn't be watching like that," he reprimanded her.

Jess just laughed.

Mark drove on, feeling guilty about all the times he'd spent on the internet looking at girls in volleyball uniforms. It wasn't like he wasn't aware his niece was hot. She was hard to miss. She was short for a volleyballer, but not at five foot five inches, she wasn't super short. She was a little bundle of muscle. He'd seen her in her bikini and there wasn't an ounce of fat on her, though at that moment, she was well hidden beneath her team sweats.

He glanced across at her, taking in her fine cheekbones and the brown hair that she'd braided ahead of her active morning. She turned toward him, meeting his gaze and smiling.

"You going to win today?" he asked her.

"Should do. We're third on the ladder and the other mob are in the bottom half of the table.

"Maybe I'll come in then." P

Jess turned and smiled at him again in response.

He pulled the truck up outside the gym and climbed out.

"Hey Jess!" he heard someone greet his niece.

"Mandy!" Jess called back. Mark turned to watch a tall blonde girl cross the carpark and grab her in a hug. She too, despite being in her sweats, was attractive enough that Mark was keen to see her in her volleyball outfit. After all, there was little left to the imagination by the Lycra shorts those girls wore.

"Mandy, this is my uncle Uncle Mark." Jess introduced him when he joined her walking to the gym. "He's being nice enough to be my Uber while my parents are away."

Mandy laughed.

"A very limited service," Mark advised Jess' friend.

"I know all about that. I don't drive yet either," Mandy told him. "And I just got dropped off, no spectators for me today!"

"Really? I thought Jess was the last eighteen-year-old in the country who hasn't gotten [7] around to getting a license."

"Not quite the only one," Mandy assured him. "I don't seem to have a problem finding a ride to most places, but all that study and practice seems so boring! School's bad enough."

"Yeah, you just push those big fat tits out at the boys and they fall at your feet and drive you anywhere!" Jess accused her friend.

"Well, it works," Mandy laughed, in her own defence.

Mark worked hard to keep his gaze from flicking to her chest. If she was well endowed, the sweat-top did a good job of disguising it. He remained wisely silent and let the girls continue teasing each other, as they made their way inside. They turned right, toward the change rooms, and he turned left to find a seat in the folding stand on the side of the court.

There weren't many people there; a few parents, who looked as thrilled to be there as he was; and a few young guys who might could have been either dedicated boyfriends, or horny brothers latching onto the chance of a perv on their sister's team-mates.

Mark settled himself in the stand and tried not to feel guilty about being there. He was clearly a first-timer, and wasn't even sure which of the supporters were there for Jess' team. He scrolled through his socials and checked his email until the increased noise level announced the arrival of the girls who were to battle it out on the court.

Most of the girls were still in sweats, but a few were already down to the tight little shorts they'd play in, providing instant eye-candy. Mark attempted not to study them too closely. As he'd noted to Jess, they were half his age! (And perfectly nubile the devil on his shoulder added).

Jess looked his way and gave a wave, which he returned with a subdued nod. Mandy glanced his way as well, and Mark found himself tracking her through her warm up, especially when she started stretching. It became readily apparent that Jess' little jab about the size of her breasts was entirely justified. Her legs were long and lithe, and her blonde ponytail bounced around as she jumped and leaped about the court.

When the game started and all the girls had stripped down to their playing attire, he was presented with a smorgasbord of temptation that he tried to diligently ignore.

He failed regularly to remain immune to the scene in front of him. He didn't think he'd ever get the image of Mandy serving out of his mind. [8]

She'd throw the ball high in the air in front of her, then take a couple of steps and leap, back arching like a pulled bow, chest thrust out in front and butt clenched tight behind. Then the stored energy was suddenly released with her arm swinging over head to launch the ball on a violent, dipping trajectory that the opposition scrambled to return.

In the moment before she swung her arm, she was a perfect goddess in flight.

Overall, he was impressed by the girls' athleticism more than anything. He'd not really thought about what standard to expect from the game, but it was well above anything he would have anticipated had he given it thought.

Jess' team came out victorious and the sight of the girls all bouncing around and hugging each other at its conclusion brought a smile to Mark's face. He was pretty sure he saw Jess cop a couple of boobs to the face when some of the taller girls grabbed her. He was only a little bit jealous.

After the game, he found himself with Mandy and Jess as they chatted about the game and their efforts within it. Jess offered Mandy a ride home with Mark's blessing and he was left listening to their incessant chatter all the way to Mandy's house.

Along the way, it was revealed that Mark had a hot tub and a discussion ensued as to how good it was for aching muscles after sport.

"We should totally take advantage of that!" Mandy exclaimed. "Maybe next week?"

"Yeah, that would be fun, wouldn't it?" Jess asked her uncle.

"If you really want to, it shouldn't be a problem. Personally, I find it better later in the day, but maybe that's because my soccer games are in the afternoon. I think the more modern philosophy would suggest an ice bath rather than a hot tub, though."

"Fuck that!" Mandy declared, dramatically.

"Exactly," Jess enthusiastically agreed. "And hey, if later in the day is better, if you're not doing anything next Saturday night, we could always come over for dinner? Mandy and I could cook for you as thanks for your playing driver?"

"Yeah, that would be fun!" Mandy agreed.

"No need to go to that trouble, but if you want to come over and use the hot tub, you can certainly do so," Mark replied, already thinking that he'd make himself scarce when they went to use it, rather than put himself in a compromising position.

"For sure, let's do it!" Mandy said, looking to her friend for agreement.

"Sure, should be fun," Jess agreed.

--- +++ ---

"You're uncle is kinda hot, you know?" Mandy said to Jess later that week as they stretched to warm up for volleyball practice.

"I think you mean he's kinda old," Jess deflected, with a laugh.

"Not that old. He's younger than your Dad, right?"

"Yeah."

"And how old's your Dad?"

"Forty-two."

"And he's how much younger?"

"Like six years, or so?"

"So he's only like thirty-six?"

"Yeah, I guess."

"So like, only just double our age!"

"Yeah, but like, old," Jess stated, defiantly.

"Fit but."

"He

is

that," Jess agreed, thinking back to the last time she'd seen him swimming. She'd been surprised by just how fit he was. He'd told the family he'd discovered CrossFit and it had done wonders for his physique.

"Can't wait for Saturday," Mandy suggested, with a wink at her friend.

"You're such a perv!" Jess accused Mandy.

The coach's whistle prevented any further discussion on the topic.

--- +++ ---

Mark pulled his truck up out the front of his brother's place, and as he'd done the week before, went and knocked to let Jess know he'd arrived. He was surprised to see Mandy with her when the door opened.

"Hey Uncle Mark," Jess said, with a smile. "Mandy stayed over last night. We figured it would be easier if you picked us both up and then just took us back to yours later. Less running around for everyone, seeing how neither of us drive."

"Um yeah, that's cool. Hi Mandy."

"Hey Mark," she greeted him, with a beaming smile. "Don't worry, we'll stay out of your hair."

"Well, just don't tell anyone what a mess the place is when we get back there. I was planning on having a couple of hours to tidy up before you two came over."

"Don't worry, you should see the state of our rooms," Jess giggled.

They climbed into the truck, Jess taking the passenger seat and Mandy sitting in the second row of the dual cab, sitting right in the middle. Every time Mark looked in the mirror, he was met by her beautiful face looking back at him, usually with a smile.

He followed them into the gym and took up a spot in the stands again, getting a few nods of greeting from parents he'd noticed the week before, though had not bothered to get acquainted with. He watched the girls go through their

warm-up

and then cheered them on during their game, which they won quite easily.

By the time they were done and back to his house, it was near midday.

"Sooooo, hot tub?" Jess suggested, as they walked up the path.

"It's probably still warming up to be honest," Mark replied. "Like I said, I thought I'd have a few more hours until you were here."

"We could chill with some Netflix until it's warm enough?" Mandy suggested.

"That works. Going to join us, Uncle Mark?"

"No, you two make yourselves comfortable, I've got some maintenance to do around the house."

The two girls settled in front of the television in the living room, while Mark mowed his lawns and tidied up around the garden.

By the time four o'clock rolled around, the girls were well and truly ready to get in the hot tub.

"Surely, it's warm enough by now, Uncle Mark?" Jess pushed, having been told half an hour before that it wouldn't be long.

"Yeah, should be nice and hot for you girls now," Mark agreed.

"And for you," Mandy prompted.

"No, I'm not getting in," he laughed off the suggestion.

"You totally should! Surely, you could use the relaxation after all those chores!" Mandy protested.

"Maybe a bit later if you're still in there," Mark responded.

"Come on, Mandy, let's get changed," Jess replied, ambivalent as to whether her uncle joined them or not.

Jess and Mandy went to the spare room and grabbed their bikinis out of the bags and changed.

"Is that a thong!?" Jess said, in shock, when she saw Mandy turn around, her red suit all but wedged up the crack of her ass.

"No, it's just skimpy," Mandy informed her.

"Skimpy is an understatement," Jess replied, settling her significantly more modest black bikini bottoms into place.

"Hey, I just wanted to look good," Mandy informed her, tying the matching red top up, and adjusting it to make sure it covered her large round nipples.

"Well if drop-dead gorgeous counts, I guess you hit the mark then. Fucking show off, I say though, putting those massive tits out there like that! And how come you tan so nicely? I can't believe you're blonde and you're brown and yet here I am, pale like a fucking ghost!"

"Hey, you're sexy as fuck, don't you let anyone tell you different," Mandy replied.

Jess sighed and settled her white bikini top in place, knowing better than to pursue the argument. Mandy was a fucking goddess and Jess, while no slouch, always felt inferior, even though Mandy was never anything but encouraging and complimentary to her. She just drew all eyes first. Between her five-eleven stature and her massive tits, jaws just seemed to hit the ground around her before anyone even thought to look at who she might be with.

They grabbed towels and went out to the hot tub. As if to confirm her view of the world, when her uncle saw Mandy, his eyes tracked her like magnets, clearly enjoying what he saw. Jess resisted the urge to tease him about it.

"You really should join us," Mandy said to him.

"Maybe later," he replied. "You two enjoy the heat."

"Thanks Uncle Mark," Jess replied with a smile, as she climbed over the side and into the tub.

"Oh my god, this is amazing," Mandy declared, leaning back with her arms resting on the side of the tub.

"No kidding," Jess replied.

Mark walked inside and nearly beat his head against the wall. He couldn't believe how sexy Mandy looked. Her bikini seemed to barely cover her incredible assets, and the fact she kept inviting him to join them had him questioning his resolve. Like, if he did join them, it wasn't like anything would happen. Shit, his niece was in there. It wasn't like Mandy would jump his bones in front of her.

He settled for checking on them occasionally, getting them some cool water to drink and making sure all was well. Each time he did so, Mandy urged him to join them.

"I think I'll wait until after dinner," he said on one occasion.

"Well if you're not getting in until then," I'll get out and get back in when you do, what do you reckon, Jess?" Mandy suggested.

"I am getting a bit pruny," Jess replied, looking at the state of her fingers. Mark couldn't help but watch as Mandy stood up, slicking back her hair and thrusting her massive breasts before her. She stepped over the side of the tub and he passed her the towel, given it happened to be within easy reach.

"Thanks," she smiled at him. He almost went weak at the knees but recovered quickly to pass Jess a towel too, so it looked like he would always have done so.

"Pizza dinner?" Jess suggested, head tilted to one side, as she towelled her hair.

"Perfect!" Mandy agreed.

They went inside and Mark ordered pizza while the two girls changed into their sweats, hanging their bikinis in the bathroom ahead of the commitment to a second stint in the hot tub.

The pizza arrived, was consumed, and everyone rested without any particular fanfare or incident. The three chatted and in Mark's case, got to know Mandy and to better know his niece. He was impressed with how level-headed and thoughtful they were about their futures and careers, but they were still well capable of being utterly frivolous teenagers as well.

Mandy was the one that eventually suggested that they'd digested the food enough to head back to the hot tub and that it was time for Mark to join them. The girls headed back to the bathroom where they'd hung their wet bikinis, while Mark went to his bedroom to fetch a pair of swim trunks.

"Ugh, so cold!" Mandy exclaimed, as she pulled her red bikini bottoms back on.

"Yeah, you're not wrong!" Jess agreed, as she tied her bikini top back in place.

"Better hurry up and get in the tub then, shouldn't we?"

"Damn straight!"

They ran through the house, laughing and squealing at how cold they were, leaving Mark in doubt as to whether they were inside or outside. He casually made his way out to join them, not wanting to give off any vibe as to how much he was looking forward to it.

"Damn Mark, you're like, fucking cut!" Mandy exclaimed when she saw him step into the water over the side of the tub.

"I work out a bit," Mark understated happily.

"A bit?" Mandy laughed. "Just enough for like a total six pack, right?"

"Exactly, just enough," he agreed.

"Bit of a transformation from a couple of years ago, isn't it?" Jess asked him.

"Massive really. I needed to do something to get healthier and it turns out CrossFit was just the ticket."

"Sure fucking worked," Mandy grinned.

"Well, volleyball is clearly working for you girls," he complimented them in turn.

"Aww thanks, glad you noticed," Mandy teased him. She was tall enough that her large breasts broke the surface of the water, all but floating. Two almost perfect hemispheres of feminine divinity. Jess' on the other hand were submerged, the water line just below her shoulders.

They chatted amiably for a while before Mandy, with the conversation having turned back to volleyball, asked Mark who he thought the hottest girl on their team was.

"Oh no, I'm not going down that path," Mark laughed off the question. "There's no good answer. If I say one of you two, the other gets put out and if I say anyone else, you both get mad at me!"

"Don't be silly, we're not that childish, are we, Jess?"

"Umm, well you

can

be," Jess teased, then continued before Mandy could erupt. "But no, we're not. It would be completely objective Uncle Mark."

He noticed she sat a little straighter in the tub after her gaze flicked across to Mandy's floating tits. It brought just a hint of her smaller breasts nearer the surface.
