My Niece startled, squeaked; and then, snarling like a seriously pissed-off jaguar she stopped riding her nearly molten pussy up and down my cock. It Was Jessica, my sort of-kind of Niece crying "Oh Hell, it's got to be my husband!" Right, I thought. Just who the fuck else would be pounding on my Las Vegas hotel suite's door? I sure didn't think it was housekeeping. But then, last heard from, her husband, my Nephew Josh was passed out in my Brother Steve's room. At the time his hot and just plain sexually insatiable wife Jessica, who just happens to be my Niece had been bent over the sofa in my suite. And, she had been wide awake, panting excited oohs and aahs as Riley drilled ten inches of thick glass dildo in and out of her ass. Riley is the utterly uninhibited blonde nympho we had hooked-up with earlier in the evening. She was gone; but, not before having wrangled a promised rematch out of Jessica.

Jessica ignored my unenthusiastic "I'll get it," abandoned my cock and started for the door. I followed; you know, just in case.

Jessica didn't even bother with the peephole, just swung the door open. But, it was Josh. At least he was dressed. He walked in, but stopped cold when he spotted my hard-on, laughing as he teased "What; did I interrupt something?" But then, sounding more like my irascible Brother, he asked "What the fuck, you do realize it's almost checkout time…right?"

"About that," Jessica began. Then, my ballsy young Niece stood there posed with her hands fisted defiantly on her hips, and looking just absolutely hotter than Hell as she explained that we had decided to stick around for another night. But, Josh was distracted; and, I figured way too busy surveying the carnage to have even heard.

"Holy shit, you guys destroyed the place," Josh grumbled, well actually managing to sound impressed. But then, he was sneering and sounding suspicious as he asked "You had to have had help; so, like what, you guys had company?"

"Jessica mumbled Oops;" already settling to her knees as she asked "My mouth is going to be full of cock Uncle Bob; so, how about you fill Josh in?"

Josh got a blowjob; plus he heard about Riley, last night's unanticipated playmate. He got the short version, not that he was paying all that much attention. Anyway, the evidence was there to see, scattered clothing, a cluttered and obviously well used bar, and of course the discarded remains from Jessica's shopping trip to the local Romanticx adult toy store. But, Josh was pointing right at Jessica's shiny new chrome and black leather dildo harness and the thick ten-inch ruby red glass cock hanging from it as he asked "Yeah, and who got fucked with that?"

Jessica's head popped up, and she huffily declared "Yeah-yeah, she fucked me, I fucked her, and your fucking Uncle fucked us both!" And then, she even more emphatically declared "Yeah and the two of us are staying for one more fucking night!" She hadn't been asking for permission, and she didn't wait for Josh to bestow it.

Josh hadn't seemed inclined to argue, definitely not after Jessica slapped a fist around his cock. Anyway, she was jacking him off, her pistoning fist a manic blur, her snarl almost a purr as she ordered "Say yes; and then, shut the fuck up …ooh, and you just better cum in my mouth!"

Josh swatted my Niece's hands away, secured her head, and filled her mouth with fast pistoning cock. But, it was me he was looking at as he asked "OK, so you're going to make sure she doesn't get in trouble…right?" I gave him my best, who me, look. "Right, forget I asked," he wisely amended. And then, after a melodramatically grunted "Yeah baby," he pulled out, one fist tangled in his wide-eyed wife's hair, the other one pumping away on a cock already splashing cum across her face.

Figuring it was just my smartass Nephew's way of saying yes; I actually started to offer a high-five. Instead, I stepped up, cried "Awesome dude," and nudged him aside with a hip-check. Blame it on his earlier door rattling interruption; whatever, it only took a few fast fist pumps and I was spritzing my Niece's face with a second helping of cum.

My Brother and Josh were gone. Jessica had moved her things in to my room, and it was barely noon. We had lunch; where else, but downstairs at our favorite bar. With good reason we were both in serious need of a revitalizing siesta. So, we retreated to our room; and, we napped. Later, after a shower and shave, I left my still dead to the world Niece and headed for the Casino.

Apparently I'd used up my luck. So, it was late in the afternoon and I was walking around hoping to bump in to my lost luck, when I spotted Jessica sitting at a blackjack table with three guys. Right away I pegged them for College boys. I wasn't sure just who was hunting who; but my grinning Niece looked ready to purr. Not that I was thinking, oh no, here we go; but, someone, like the dealer maybe, should have told her to keep her hands up where he could see them.

Jessica greeted me with a cheery "Hey, it's Uncle Bob!" And the next thing I knew, I was agreeing to buy her and her friends a drink.

In the bar, shots were ordered and introductions were made. So, I met Jimmy, a wise-cracking geek type, Ralph a buttoned-up Finance major, and Carlo, a hulk who played football. They invited us to join them for a visit to one of the local strip clubs. Of course I expected my already obviously sex-charged and outrageously flirtatious Niece to be all in; but, no. And, Already suspecting ulterior motives, I listened to her tell a rapt audience about the time she'd been goaded in to dancing on the bar at the local American Legion Post.

"My husband Josh is a vet," she explained. "We were drinking at the bar, and it's all his fault, because he dared me! So, I was up there waving my bare tits around; no shit, and I was down to nothing but this ridiculously short skirt when the bartender unplugged the fucking jukebox. Yeah, and Uncle Bob's favorite Nephew wouldn't have stopped me; but, the sweetheart did carry me out of there," she told us. "I was totally trashed, guess I'm just a bad girl," the flirt needlessly added.

Yeah, I thought. But then, you're awfully good at being bad. And then, I decided to say it out loud. And, that's when Jessica got up, on her way to order another round when she stopped to whisper in my ear.

It was a dare; no shit, my Niece actually dared me to invite the guys up to our room. I would have known what she had in mind without her giggle or the blatantly wicked way she tongued my ear. Still, a four man gang- bang wouldn't have been my first choice; but then, what were the odds of another Riley showing up?

"Boys," I said. "Jessica thinks the four of us could have a lot more fun up in our room than out at some strip club," I told them. And, figuring, what the Hell, went all in. Honestly guys, after the sexual high-jinx she's instigated over the last couple of nights, I think you can count on it!" And then, I answered their understandably curious stares with a shrug and a sighed "Hey, she's really just my crazy Nephew's wife!" As if that explained anything, while the Niece in question distributed shots, I told them about the wild no-limits three-way Jessica had wrangled Josh and me in too way back on night one.

"Ooh yeah," was Jessica's response. Well, that, and a casually delivered "Seriously, it was almost as much fun as last night's three-way with Riley, wasn't it Uncle Bob?" My enthusiastic nod didn't quite seal the deal. It took some silly reassurances, Jessica's scandalous description of Riley, and a couple of the juicier tidbits from our second night's fuck-fest.

Up in the room, there was Tequila, and I was pouring when I heard Ralph ask "You're sure Jessica? I mean, Jimmy's half-crazy, and if you believe the rumor, Carlo has a freaking ten incher!"

"Crazy works; and oh my God, last night I was packing a ten-incher of my own," was the bombshell Jessica enthusiastically fired-off. And, when it was met with understandable skepticism, she was quick to deliver on a teasing "Oh my, guess I'll just have to show you cynics." So, as my giggling Niece dashed for the suite's bedroom, I was expecting more show and tell. What could I have been thinking?

Jimmy was fiddling with the room's tiny stereo, when Jessica made her grand, jaw-dropping entrance. And, except for her gleaming chrome and black leather dildo harness she was naked. Yeah, and she was strutting, ten inches of thick ruby red glass cock on display. That shut those college boys up. It shut me up too; and, I'd been there watching her fuck Riley with it. Hell, I'd watched Riley fuck my Niece's ass with it. Jessica stopped, clearly center stage as she squeezed a bit of lube from a bottle I'm sure none of us had noticed in to her palm. Then, as she ran that lube-loaded hand suggestively up and down her glass cock's full length, she positively purred "OK guys, who wants to be first?"

I didn't panic, but only because she hadn't even spared me a glance. It was on me, and all I could think about was this totally dumb-shit move I'd made the night before. Hell, I'm forty-three and should have known better…yeah, as if. Anyway, late last night, Jessica was lying stretched out on our room's king-size bed, that glass cock jutting up out of her harness. She was growling like an impatient Jaguar. I was right there, watching Riley getting it ready for a ride, her breath coming in sharp gasps as she lubed it up. In the careless, smartass move of a life time, I rolled on to the bed, actually grinning as I came up on my knees straddling Jessica. I was fooling around, not offering up my ass. I sure as hell had no intention of following through. Still, I had that monster's big head right there, pressing right up against forbidden territory. And, there I was thinking about just how much of it there was, and not paying any attention to Jessica. I still don't know if she was snickering or giggling; whatever, all it took was an upward bounce and, well it wasn't only my eyes that opened wide. But, she was definitely snickering when she teased "Way too late to start clucking like a chicken Uncle Bob!" It wasn't; but, I didn't.

Jessica snarled, yeah like a Jaguar and began to work her hips. I bounced, feeling her gentle thrusts go deeper; groaning when some of them included a repeat of her opening move. I kind of tuned out, tuning back in when I felt Riley's fist close around my cock, my surprisingly way past semi-hard cock. So, Riley was jacking me off, when my clearly over excited Niece picked up the tempo, not to mention the depth of her suddenly forceful thrusts. Still, when she stopped snarling grunts, I heard her franticly order "Oh fuck yes, make him cum Riley!" Riley was on it, and I was only too happy to cooperate. It was better than getting a root canal; yeah, and like a root canal all you want is for it to be done. But, unlike a root canal, my tribulation ended with me joyously splashing cum all over my gleefully whooping Niece's tits and belly.

Jessica didn't share that nasty little tale with her trio of gaping would be playmates. So, as the saying goes, no harm no foul. And, when no one volunteered to go first, Jessica joined me at the bar. She did a shot, and was holding a second one, her fingers still lightly stroking her jutting glass phallus when she huffed out a dramatic sigh. "No takers…bummer! So, how about this," she teased, downed her shot and said "First one of you to get naked gets to take it off me." I think it was the promise in her growly "And then," that did the trick.

Jessica watched their comical and hurried strip tease, and I watched her. "You too, get with the program already," Jessica growled, before jabbing a finger at Carlo. But, her barked "You too," was aimed at me. I shrugged, began to strip, and Carlo followed suit.

Clearly looking like a guy who wanted to win, Jimmy had his arms raised in a victorious salute while Ralph was still dancing around trying to get his shoes off. Jessica's slow round of applause screamed of ho-hum; but, after crooking a beckoning finger at Jimmy she stood there with her fists planted firmly on her hips. Jimmy the wise-guy was wise enough not to keep her waiting.

Jessica's eyes were on Jimmy's cock, a standard size unit with a bulbous over-sized head. His eyes were on Jessica's impressively jutting ruby red glass dick. And, like maybe he didn't quite believe it, he reached out, tentative as he tapped it with the ring he wore on his ring finger. "Yup, glass," he confirmed. And then, while managing not to touch my snickering Niece's glass penis, the nervous guy quickly undid the trio of buckles holding her harness in place. He dropped it, his "Fuck, check it out," a surprised yelp. Apparently the harness had been hiding the evidence, because Jimmy fired off a loud "Oh shit, the chick's shaved freaking bare!"

Already on her way to her knees, Jessica hissed out a snarl. Then, she grabbed Jimmy's skinny but, yanked him forward and closed her lips around his cock's big head. The poor startled guy was still in mid-gasp when those lips closed around the base of that cock's shaft. Then, with her head on a slow bob she repeated herself, repetitively swallowing the head and then the rest of Jimmy's cock. Impatient with slow, Jimmy tried, clearly wanting to fuck my niece's mouth. She wasn't having any of it. And then, when she was good and ready, she stopped that maddeningly slow head bobbing, hands back on her hips, her eyes zero-in on Jimmy as she ordered "Do it, fuck my mouth stud!"

Like maybe he was afraid of running in to a stop sign, Jimmy was franticly drilling his entire wetly glistening length in and out through Jessica's lips, when she waggled a come hither finger at Ralph. And, that buttoned-up finance major didn't even wait for the order to come down in writing. So, Jessica had a fistful of Ralph, when Jimmy bellowed "Aah fuck," his manic thrusting suddenly jerky. She swallowed, all but a final miss-timed eruption that wound up on the carpet. Then, with a growl, striking with the speed of a Jaguar she licked up the smear of cum dribbling from Jimmy's cock. A second strike, and she had the head of Ralph's cock lodged in her throat. No shit, the guy's knees actually buckled. Her pumping fist had primed the pump, and poor Ralph quickly succumbed. He did get his hands in to her hair; but, it was still my Niece doing the bobbing as his explosive "ooh," heralded my Niece's second helping of cum.

Carlo didn't get to cum in Jessica's mouth; but, he did get to plant the enormous head of his big thick dick in her throat. He was sitting on the sofa, where she had ordered him to park his ass. And, of course she utterly ignored his "Damn girl, no one's ever taken it all that easy!" Well, at least I was impressed, not that I let that stop me from jumping in. And, there was a reason why Carlo was seated; and, it wasn't because she wanted to show off her prettily shaved pussy. Coming from my shameless Niece, It was a boldly displayed invitation, one I jumped to accept. So, while she sucked the big guy's balls, her fist almost lazily pistoning up and down his ten incher, I hurried over and plugged my raring to go seven incher in to that deliberately exposed pussy. Carlo had started to dribble my Niece's head, and I was jamming cock in to her just as hard and fast as I could, when she swatted his hands aside and snapped a growly "Back the fuck off Uncle Bob!"

Jessica's untimely intermission call just gave her the chance to move the party in to the bedroom. She ordered Carlo to lie down, considered, and suggested "No, across the bed!" And, I was sure I knew why; because, I knew a secret. Down in the bar, back when my Niece had been whispering in my ear, sure, she had dared me to invite the boys up to our room. And, if I'd been silly enough to think she wasn't thinking gang-bang, her breathy "Maybe I'll finally get to do that air-tight thing," erased any lingering doubt.

Jessica had clambered up, swung a leg over, lined things up with a wriggle of her ass, and with a snarly grunt and a bounce she had impaled herself on Carlo's studdly ten-incher. I checked and all eyes were locked in on the sight of that thick cock's pussy drenched length getting bounced up in to my whooping Niece. But, whose move was it? Not sure, when Jessica leaned in, still rocking and grinding against Carlo as she kissed him, I made a move. Actually, I waited until she was back up on her knees; and then, I reached up, snagged a fistful of her hair, imitated one of her Jaguar growls and yanked her head down. And then, before ordering "Suck my dick," skipping the please, I suggested she lick her pussy's juices off it first.

My mistake was in picking Jimmy. I mean; the guy was standing there stroking an already resurrected hard-on. But, I waved him over anyway, and didn't bother to whisper as I asked him to fetch the bottle of lube Jessica had left in the other room. Oh well, no biggie, I told myself. After all, back there on night one, I'd taken my Niece's ass, with her bent over the sofa and giggling. Her husband had enjoyed our performance so much he'd followed my lead, stopping long enough to tease her with an encouraging "Oh yeah, my wife the insatiable slut," and a not quite as teasing spanking. But, then, as he was splashing a load of cum across her ass she was actually giggling as she pleaded "Going to spank me Uncle Bob?" Cum glazed, which it most certainly was, I spanked my Niece's twice fucked ass.

I didn't mind being stuck watching Jimmy lube-up; after all, I hadn't even been able to see his lube loaded fingers back when they'd first penetrated my Niece's ass. And even if I couldn't see it, I could tell he was churning them as he pumped in a steady round of slow thrusts. Seriously, the dopy guy hadn't even spanked her first; besides, she was sucking my cock. At least I was part of the team as Jimmy turned her airtight.

Before things wound down that night, we all had a go at Jessica's ass. I was on my back, banging savage thrusts up in to my panting Niece, but backed it down, and just so Carlo could screw ten inches of cock in to her ass. And then, we both fucked her, the feel of his big thick dick tunneling in and out of her ass adding a little something extra. Still, maybe I shouldn't have entertained the guys, telling them in graphic detail about how I'd spanked my whooping Niece's twice fucked ass despite it's being glazed with my Brother's freshly deposited cum…oh well. Does that make it my fault that Carlo pulled out, laughing his fool ass off as he unloaded all over my unable to protest Niece's ass? No, and if her mouth hadn't been full of cock at the time? Never mind, it wouldn't have changed anything. My hands would still have been sticky with Carlo's cum when I took my turn, which I did, right after the big guy tired of spanking my giggling niece's ass.

The boys were gone, the worst of the mess had been cleared away, and I was contemplating another run at blackjack. Jessica was looking bored, and that worried me. After all; three nights, wild over the top sex with two exceedingly hot and willing young ladies, a wicked four-way gangbang, damn straight, I was feeling sort of jaded. But then, Carlo called. Eye contact and a flash of Jessica's mischievous grin was all it took. And, it's not as if I had a choice; fuck no, so I nodded, and just like that Carlo had wrangled an invitation. What the fuck, who wouldn't be eager for a return engagement with a shamelessly insatiable hottie, one ready, willing, and able to deep throat ten inches of hard cock? Yay… Jessica!
