Hell no; what happens in Vegas doesn't always stay in Vegas. And, my Nephew's hot young and sometimes outrageously flirtatious wife is only technically my Niece. That didn't matter; at least not before the call from my older brother Steve. His invite to a last minute Las Vegas trip was an unexpected surprise. But, seeing as how I work from home and can almost always make time for a Vegas run, I eagerly agreed.

My Brother and his wife are both recently retired; but as he explained, she wouldn't be joining us. Then, when he asked me if I thought he should call his son Josh, my immediate response was an enthusiastic "Hell yes, call him!" Steve made the call and both my Nephew Josh and his wife Jessica, my sort of-kind of Niece eagerly signed-on for the mid-week trip. They agreed to share a room with Steve, and I reserved a mini-suite in the same off-strip Hotel for myself.

I'm forty-three, divorced and a happy bachelor. The Ex and I are still friends, good friends actually-which yeah, means friends with benefits. And, we were never exclusive. We did some swinging, but preferred to party with friends. That only figures in to this story because Josh grew up hearing the bawdy stories my big-mouthed Brother couldn't resist passing along.

Josh is twenty-five, and like his Uncle he is a pretty good looking guy. Way more importantly, Jessica is twenty-three, a wickedly curvaceous Latina with big dark eyes and dark shoulder length hair. She also has a very sexy butt and a pair of eye-catching, cock-hardening boobs, big ones, round, firm, and as I would discover boobs that were exceedingly fuckable. Oh yeah, and the girl isn't just an outrageous flirt, she's a shameless tease, something she doesn't mind at all admitting to. Did I flirt back? Hell yes; you better believe I did, not that I ever expected to do more than conjure up erotic fantasies…which, I did.

The drive to Las Vegas is typically a five hour slog, which for that trip anyway meant a mid-afternoon check-in. My room came with a king size bed, sitting area with a pair of small sofas, and a neat little bar with two nicely padded stools and a well-stocked mini fridge. I hadn't brought along enough to bother unpacking. But, I did deposit a bag of toiletries in the bathroom. I changed my shirt and headed downstairs where the four of us planned to rendezvous at one of the casino's many Bars.

Other than the bartender I doubt anyone took notice of my Brother, my Nephew, or me. Jessica on the other hand; wow, she showed up squeezed in to slinky hip-hugging jeans and a revealing hot pink midriff baring tank top. And, she hadn't bothered with a bra; so yeah, I wasn't the only guy gawking. Even Steve, her father-in-law stared, which at least didn't get in the way of his ordering another round of drinks. It was just beer for Steve and me. Josh pounded a second Tequila shot, watched his vivacious wife down her's; and then, after declaring "Hey, you're one behind" he ordered her another one. Later, but not all that much later, after agreeing to meet back at the bar we split up and headed off for a bit of gambling.

I was having way too much fun, actually winning; so of course it was time to rendezvous back at the bar. I was playing Blackjack had worked up to a hundred dollar bet and had just been dealt a blackjack. Hey, it was a big bet for me; so yeah, big yippee. Fuck that; I nearly knocked over my beer when a pair of arms wound around my neck and a pair of soft lips smacked an ear-ringing kiss off my ear. It was Jessica and she followed up with a squealed "Fucking awesome Uncle Bob," and a second, and even more attention-grabbing kiss. So yeah, I forgave her, and not just because of the wicked way the tip of her tongue had danced teasingly around my ear. Oh sure, Josh is my nephew, so I suppose that makes Jessica my niece. But, with her practically frenching my ear as she pressed her soft, hard-tipped boobs against my back; well Hell, no way was I thinking Niece.

The four of us had dinner on The Strip, tried our luck in a couple of the big name Casino's, and eventually wound our way back to our off-strip hotel. Jessica had changed before dinner and was wearing a scandalously short black leather skirt and a clingy, booby hugging flame red silk cami top. And no, she hadn't bothered with a bra…so yeah, ooh! But, I wasn't thinking about Jessica, her magnificent, might as well have been bared boobs, or their jutting, unmistakably erect nipples. No, I was just another frustrated up a bit-down a bit Blackjack playing fool. Or, at least I was right up to the moment Jessica sidled-up, her hands on my shoulders as she bouncily declared "It's me!" She leaned in, letting a hand rest way up high on my thigh, its fingers circling, stroking as she whispered "Steve is like, you know a total party pooper. Anyway, he's up in our room, and if the old fart hasn't crashed, he'll be watching TV. So, well Josh and I were wondering if maybe you'd like to hang with us up in your room?"

I was up, and in more ways than one. So, aroused, curious, and in general feeling pretty good about things, figuring why not, I agreed. A stop at the bar was of course obligatory. Shots were ordered and quickly shot. And still, the first thing the kids did up in my room was raid the bar's mini-fridge. I plunked myself down on one of the bar stools, Josh flopped on to one of the sofas, and Jessica dialed in some music.

Josh and I watched Jessica dance around the room. When she liked the tune she moved like she was auditioning, eager to land a job at one of The Strip's many strip clubs. And, when the music didn't move her, she'd wander over, rubbing my shoulders and stroking my thigh as she flirted brazenly. I managed to restrain myself, only lightly running a hand up a bare thigh and only after her stroking hand had slid over the hard-on bulging my jeans. Her –cock-teasing hand didn't show that much restraint. It did seem to be on offer; so, I did slide my hand higher, around and briefly over Jessica's silkily smooth bare ass. And all that did was add fuel to the fire already flaming in my pants. I was curious; were there panties, or had my fingers been mere inches away from naked, utterly accessible pussy?

Whatever Josh was thinking, he was watching us, and I liked that he was grinning. I had about decided to just go for it, do a bit more exploring and maybe get an answer to that lingering all important question. But, when Jessica gave my cock a hard lingering squeeze and breathed a steamy "Nice," in to my ear I hesitated. And then, before dancing away, and in full view of Josh, she treated my erection to some slow, sensuously delivered stroking.

Jessica danced away, laughing as she spun around the room. And, she was still laughing when she dropped in to Josh's lap. He got kissed, and he got groped. She was shameless, reaching between her legs her groping hand practically jacking my grinning Nephew off. Then, it was a gasped "Yes" when his hands cupped her tits. She leaned back, moaning oohs as he pinched a pair of jutting nipples. Then, those damn hands were up under that silky cami and he was whispering in to her ear. She bounced, wriggling in his lap, her eyes on me as he went right on openly manhandling her tits. When he told her something I didn't quite catch, I saw her eyes go wide. Like, as if I needed something else to wonder about.

"You're daring me…really," Jessica asked. Josh laughed, and after calling him an asshole Jessica scrambled around, coming up on her knees straddling him. And, that's when I got one of my questions answered.

Josh's hands had slid up under Jessica's short skirt. He didn't bother to push it up; and he didn't need to, not to leave her ass exposed anyway. I was all set, expecting to get a peek at my Niece's deliberately exposed pussy, hopefully shaved bare and already glistening wetly. Instead, all I saw were Josh's hands slip-sliding over the sexy curves of an almost bare ass. Question answered; yeah, there were panties, or at least a slinky, barely there flame red thong.

There I was, horny and feeling sorry for the poor neglected hard-on throbbing away in my jeans. I was hoping for more when Jessica bounced to her feet, so, she was center stage, her moves raunchy and raw as she danced. Nasty doesn't even begin to describe her idea of dirty dancing. No imagination needed, she was mind-fucking me. Still, it was my Niece, my Nephew's wife, my Brother's daughter-in-law; not that any of that kept me from picturing it. My hands would have shredded that thong as I tore it off her, a slap to her ass bending her over as I caught her by the hips, my cock driving balls deep with one uninhibited thrust. Instead, I stared, barely believing my eyes as Jessica worked a slow bump and grind while fondling her tits. She cupped them, squeezing them together as she bent her head, her tongue flicking out to lick a pair of unmistakably erect, but still silk covered nipples. I thought it, but it was Josh who cut loose with a whooped "Damn girl!"

Jessica didn't so much as glance his way. But, she did peel her silk cami top up and off over her head. She flung it away, giggling as she smushed a pair of bare tits together. Head dipping, one at a time she whipped the flicking tip of her tongue over a pair of dark aroused nipples. And then, earning a groaned "Oh fuck," from Josh, she sucked them. So yeah, I was still stuck in speechless when she looked up, her voice a breathy tease as she said "Josh says you wanna fuck my tits!" It was a statement not a question.

It was true; not that Josh had heard it from me. It had to have come from my big-mouthed Brother. Sure, it remained to be determined; but, for a change I thought that just maybe I have to thank the blabber mouth. Anyway, while hungrily eyeing my Niece's tits, their freshly licked nipples still glistening, I missed the move that dropped her skirt to the floor. So, I was gawking at the miniscule triangle of lacey red thong that blocked my view when she asked "Well, is he right?"

It took a while, like forever; but, I finally managed a respectively emphatic "That would be a Hell yes!" But, by the time I got it out Jessica was on her knees that damn red thong still leaving one question unanswered. My money would have been on shaved bare, wet, and looking ready to be fucked pussy. But then, it was those fuckable looking tits I was being offered. My Niece made that clear, huskily insisting "Come on Uncle Bob, do it, fuck my tits!"

I looked over at Josh. He was grinning, which was good. And, I chose to read his shrug as a, go for it dude. So, I had my dick out, seven inches of rock hard cock leading the way as I started for the kneeling girl excitedly cooing Oh yeah-oh yeah, he's gonna do it!"

Jessica's snappy "Not so fast" brought me up short. But, before I could even think WTF she was working my belt loose. So, my jeans were down around my knees as I pushed my dick between a generous helping of smushed together tits. That sweet cleft was hot, silky smooth, felt just fucking awesome; only, it wasn't slippery, not like ready to be fucked pussy. But, Jessica had a solution. "Well hey, it works better when it's all wet and slippery," she said, her hands already fastening around my hips. I watched her lips close around the head of my cock. A heartbeat later those lips had slithered down seven inches of cock and were snugged tight around its base. I waited, my eyes flicking back and forth between Josh and the wife whose mouth was, not coincidently full, jam-packed with hard cock. They weren't there to stop me, and Jessica's hands dropped away as I began to work my hips, soft slow thrusts plunging my full length in and out through her lips. So yeah, my cock was wet, slippery, and dangerously hard when I reached for her tits. It wasn't pussy, and I'd rather have been fucking my Niece's mouth; still, well yeah…ooh!

Jessica's tits are bigger; and just then, the ones I was energetically fucking. But then, my Ex's tits were just as fuckable. And, not only did she like it, she liked it best when I left her tits glazed with cum. What about Josh, I wondered. What is he expecting, maybe even hoping to see?

Josh was watching me fuck his wife's tits; I knew because I kept checking. And, I knew he'd been watching back when her head had been bobbing, seeing her suck as seven inches of wet cock slid through her lips. He must have liked it…right? I would have. But, just then what I wanted was him watching me fuck his hot and apparently utterly uninhibited wife's mouth. Fuck that, I wanted him to be sitting there watching, wide-eyed as I flooded that mouth with cum. First though, I had some titty-fucking to do.

Jessica's tits were in my hands, and I was almost lazily fucking those beauties, when she pushed me away. Surprised, I wasn't expecting to hear an insistent "Cum in my mouth, oh fuck yes, I want you in my mouth!" No problem, I let go of her tits and reached for her head. I wasn't a beast about it; beginning slowly, letting her suck as I powered gentle half-jabs through her lips. Then, when she grabbed my butt, I figured it for a hint. So of course, I began to pick up the tempo, rotating my hips, no longer holding back as I fucked her mouth, generously feeding her my entire seven inches. She took it, eyes wide and looking up in to mine. She didn't balk, not even when I began to twist in harder, and then even harder thrusts. It was time, and wanting to make sure Josh knew it, I whooped an alert. Jessica didn't care; she'd already tightened the manic grip she had on my butt. So, I pumped cum in to her mouth, deep lunging thrusts spewing most of it in to her throat. It wasn't enough for her, and it was her fist that coaxed loose a final titty splattering ejaculation.

Me, well I was just standing there, still semi-erect, but also pretty much brain dead when Josh pulled Jessica to her feet. He was naked, and I wondered just when the fuck that had happened. Jessica had noticed, fists planted on her hips as she challenge Josh with a growled "You just better be planning to fuck me stud!"

Josh barely gave her time to push her thong down. Actually, she was still bent over trying to work it free when he cracked a swat off her ass. I heard her suck in a sharp breath, and then snicker as she tossed her thong aside. She remained bent over, still softly snickering as she spread her long legs wide. She grabbed her ankles, her "Fuck me," a snarled order.

Josh was right there, laughing as he reached for her hips. And, he just absolutely slammed a thrust up in to her. She gasped, chanting out oohs as he continued to brutally rip fearsome thrusts in to her. And why not, the young stud was kind of hung, thicker and longer than me.

Enjoying my close-up view, I stayed put. I really liked the way almost all Josh's powerful thrusts penetrated her, disappearing with a ringing slap as he ran out of cock. His cock's big engorged head just kept opening her up, thrust after hard pussy piercing thrust. Anyway, much as I liked watching, I was ready for a turn. And, seeing as how Josh was pretty much fucking her like a guy with nothing more than cumming on his mind, I figured I might just get the chance. But then, he slammed on the brakes. He stood there grinning, his big dick utterly rigid and sopping wet. "I know you like the taste; so, how about I feed you seconds," he asked, chuckling as he added a teasing "Gosh, and I'll even try not to spill any on your tits."

Josh was back on the sofa, leaning back, hands behind his head, his legs spread wide apart. Jessica was on her knees her head bobbing, cheeks working like mini-bellows as she sucked. Did I ask permission? Hell no, I just dropped down between her legs, my hands lifting and spreading her ass's cheeks as I entered her. Even after the wicked fuck Josh had delivered, her vagina was a nice snug fit, a hot, slippery cock hugging fit. Two slow deep strokes and my cock already glinted, drenched by a flood of her pussy's slippery juices. I liked penetrating her, and with her preoccupied I knew hard and fast would work better for at least one of us. So, I was putting some extra bounce in to her bobbing, making like a jack hammer as I pounded cock in to her when Josh settled a hand on her head. He gasped a half-grunted "Oh fuck," and pushed her head down. I was right behind him, wildly banging cock in to her just as fast and just as hard as I could. But, there was a micro-seconds of hesitation as my sex bedazzled brain considered. I could make it thirds, pull out and feed her another helping of cum, but figured Josh would rather watch me drench her pretty brown ass under a rain of cum. And, even if I'd wanted too, it was already too late. Taking my Niece's ass would have to wait. So, her pussy gobbled up my entire load; and for the time being anyway, Jessica's ass remained pristine.

OK, so the boys were up three-zip, not that Jessica pitched a bitch. But then, she didn't need too. Josh and I, knowing the best way to maximize our pleasure was to maximize her's, maximized away. Anyway, the sun was up before my insatiable Niece gave it up and finally called "Enough!"
