An Offer He Can't Refuse Ch. 08

"Oh! So I am the cock-crazy bitch, uh?" Jennifer snickered, playfully smacking Julia's plump bubble-butt and making her yelp in surprise. "Sorry missy, but I'd say that I'm not 'the slutty one' anymore, you know, what with you fucking your own son and all! That's so hot, though, even saying it makes me wet..." Jennifer exhaled sultrily as she let her caressing hand linger on her sister's juicy booty, her fingers digging into Julia's fleshy asscheeks.

"Mmmh, I know..." Julia purred, her pussy still tingly and needy despite the numerous climaxes she had already experienced that evening. "I haven't had Mike's cock inside me for less than a day and I already feel like I'm in withdrawal or something!"

"So, Jules, just to be clear," Jennifer resumed, her voice husky with arousal, "would you please allow me to have a go at my studly nephew's huge dick when we get back? Please, sis, pretty pleeeease?"

"Ugh, fine... I guess it's okay for Mike to fuck his slutty aunt too, since he's royally pounding his mom on a daily basis already!" Julia replied, exhaling in mock-resignation and rolling her eyes at Jennifer yet grinning all the while, devilishly turned on by the tangle of forbidden desires rotating around her beloved son. "But I demand to be there too, Jenny. Mike is my sweet boy after all, he'll need his mommy's help to deal with a nasty cougar like you!" Julia concluded in a teasing tone while looking askance at a hooting, exultant Jennifer.

"Yay, I get to fuck my nephew! Thanks, Jules, you're the best little sister ever!" Jennifer yelled out, laughing and squeezing Julia in a celebratory bear hug that made their massive melons get squashed sexily together.

Caught up in her big sister's lewd enthusiasm, Julia didn't even blink as Jennifer's tumid lips made contact with hers in a deep, spontaneous kiss. Instead, all turned on and tingly as she was, with her mind swirling with naughty thoughts, Julia joyously reciprocated Jennifer's smooch, initiating a languid make out session. As the voluptuous blonde mothers traded kiss after moaning kiss, memories of their many past sapphic sessions flooded both their minds, reigniting the familiar mix of affection and lust that each of them felt for the other and that they both had held dear since they were young and horny girls going through their very first sexual experiences together.

Even though they hadn't lezzed out in a relatively long time, being together like that came as second nature to both Julia and Jennifer. Seamlessly, as their tongues danced and their lips joined over and over again, the busty sisters reached their hands to on another's pussy and began fingering each other as they pressed their bulging tits even closer together, like they had done so many times before. Their practiced lip-lock was only broken when Julia, already close to another orgasm thanks to the talented ministrations on Jennifer's slit-diddling digits, suddenly pulled back and yelped in delight as she felt the fingers of her big sister's other hand slip into her luscious butt-cleavage and start to tease the sensitive, gummy ring of her butthole.

Smiling as she enjoyed both the sight of her little sister's pre-orgasmic expression and the squishy wet motions of her own digits pumping in and out of Julia's juicy pussy, Jennifer eased her index and then her middle finger into Julia's pliant anus, pushing them slowly but surely all the way in, until they were buried knuckle-deep inside the warm tightness of her rectum and Julia was crying out in a sudden, stabbing climax.

"Fuuuuck! Oohh Jenny, yeeess!" Julia whimpered as her big sister masturbated both her holes with a mastery born not just out of long practice, but also out of the sort of closeness developed over years of growing up together and sharing pretty much everything.

Curling her digits inside Julia's pussy to rub her g-spot while she steadily finger-banged her anus, Jennifer brushed her lips against her ecstatic, girlcum-gushing sister's O-shaped mouth as she murmured: "Yes, baby sis, cum for me... Mmmh I've always loved to make you cum like this! Oh my god, Jules, think about having Mike here too now..." Jennifer added dreamily, causing Julia's breath to catch in her throat as her orgasm reared up again at the mere thought of having her son's fantastic cock pumping inside one of her holes while Jennifer's fingers twirled within the other.

Loving how Julia reacted to her words, Jennifer went on, her genuine anticipation dripping in her husky voice. "It's gonna be so awesome, Jules! You and me and your big-dicked boy are going to have so much fun, together I know it! Oh fuck, I can't wait, Jules!"

With her pussy and asshole squeezing in climax around her big sister's amazing fingers, while her head spun crazily and her liquid pleasure overflowed her ever-needy slit, Julia couldn't help but yell out her willingness and urgency to see the scenario that Jennifer's lustful words had just painted actually come true.

"Oohh yeeaahh, Jenny! Yeeeahh..." Julia screamed, meeting her grinning sister's lustrous eyes and pressing her tits against hers even more firmly as she planted frantic kisses on Jennifer's full, smiling lips. "Uuhh fuck yeeess... Yeesss, yeeeeeess!"

Waking up late in the morning after a night of amazing sex, Mike had a big smile on his face as he yawned and rolled over, unwilling to return to full consciousness just yet. Slowly emerging from his deep, refreshing sleep, the groggy teenager hummed with satisfaction while delicious images from just a few hours earlier flashed before his heavy-lidded eyes.

Still frames of Lyla's epic ass and huge tits overlapped with the hottest and most intense moments of their incestuous fuckfest. The memory of the balls-draining blowjob/tit-fuck that his gorgeous sister had treated him to was still fresh in Mike's mind, as was the emotional awe he had felt when she had ridden him cowgirl style, making him howl with pleasure as the soft folds of her snug little pussy massaged his raging cock and bathed his length in her dripping girlcum. Most of all though, what made Mike's morning wood turn into rock-hard steel were the unforgettable recollections of how Lyla had enthusiastically invited him to pop her anal cherry.

Groaning with renewed arousal, Mike rolled onto his back and reached into his boxers to grab his hugely swollen boner while in his head he replayed his first assfuck with his sister. Savoring every moment all over again, the half-asleep teenager slowly stroked his fat dickmeat as he thought of just how deliciously warm and tight his big sister's virgin asshole had felt as he penetrated her pink little rosebud and gently slipped into her smooth cock-hugging rectum, widening her anal depths to new dimensions before he started sodomizing her for real, plowing her anus harder and deeper with each thrust, much to their shared forbidden pleasure.

The mere recollection of how he had blown two massive loads of cum deep inside Lyla's heavenly butthole and the intoxicating memory of just how much she had loved the sensation of his semen inundating her buttery bowels almost pushed Mike over the edge all over again. On the other hand, the fact that Lyla had sensibly opted to leave his bed and retreat to her own room before Lori came back had been a bummer for Mike the night before, and it still felt that way even in hindsight, to the point of temporarily dampening his horniness and slowing his dick-pumping rhythm.

Still, Mike's horny albeit half-asleep mind immediately conjured up other naughty scenarios, this time involving Lyla and Lori licking each other's pussy while locked in a sensuous sixty-nine. Based on what Lyla had told him, that kind of stuff happened almost on a daily basis, so Mike thought it very likely that his sisters had lezzed out the previous night after Lori's return, while he was already sleeping soundly with a smile on his face.

Letting the swirl of his forbidden fantasies and hot memories bounce around in his head, Mike stroked his morning wood a bit more before finally deciding not to jerk off to completion after all. As much as he enjoyed fantasizing about Lyla, he was much more interested in actually blowing his load inside her again, something which she herself had assured him would be happening again soon. Also, Mike reasoned as he groggily got out of bed, later that day his mom would be coming back home, and he was sure that she would be as horny for him as he always was for her.

The mere prospect of his beautiful curvy mother jumping his bones sent yet another jolt of arousal to Mike's meaty shaft and broadened the grin on his face, causing a host of sexy mom-centric images to pop up in his head. Unbidden yet predictable, the thought that at some point he might have to tell his mother about having had sex with Lyla did pass through Mike's mind, but he was glad to realize that he felt neither guilt nor fear associated with it. Deep down, he knew that his mom would understand and realize that his relationship with Lyla was simply evolving for the better, just like their mother/son relationship already had. In fact, Mike pondered, his mom would probably be happy to know that he and Lyla were even more intimate than before.

'Maybe she'll get turned on about it... I know I am!' Mike thought, chuckling to himself as he sleepily made his way into the bathroom to take a strategically cold shower.

As he stripped naked and took a look at his rampant morning hard-on, Mike was tempted again to just stroke one out, but he managed to exert enough willpower not to do it, stepping into the shower stall instead.

Trembling under the spray of pelting ice-cold water, sighing as he watched his raging boner gradually deflate, Mike gritted his teeth and reminded himself that it was worth saving his cum for his sister and mother's willing holes rather than waste it jerking off. If he played his cards right, he reasoned as his morning horniness evaporated and his erection wilted under the frigid shower, he might even get to fuck them both that very day.

"N-n-now th-th-that's a w-w-warming thought!" he stammered to himself as he stepped out of the shower and toweled off, grinning at that naughty prospect even as he shivered from the cold.

Except for a couple of times when Lyla snuck up on him to teasingly push her round shorts-clad booty against his crotch and grind away while winking at him only to then cup his chubby cock through his pants and bounce away chuckling, the day went by pretty normally for Mike. Lori seemed in a better mood than usual, which he interpreted as a sign that she must have either hooked up with some of her high school girlfriends at her party or, even more likely, with Lyla later at home. As for Lyla, beside the moments when she teased Mike with her spectacular bubble-butt, she was her usual relaxed and whimsical self with both her twin and her little brother.

After lazing around by the pool for the better part of the morning and early afternoon, the three of them had a late lunch together, during which Lyla claimed the very last slice of their mom's chocolate cake for herself by unapologetically stuffing it into her smiling face while her siblings were busy squabbling over who should have it and why. Once they finished straightening up the kitchen and washing the dishes, chores which fell mostly on Lyla as the chosen punishment which Mike and Lori agreed to inflict upon her due to the cake incident, Mike watched with a knowing grin as Lori whispered something into Lyla's ear while grabbing her by the hand and dragging her away.

Under different circumstances, Mike would have thought nothing of it, what with Lori having always been kind of needy and prone to demand some alone time with her twin. Still, in light of Lyla's recent revelations, he couldn't help but wink and flick his tongue suggestively as he caught his curvy big sister's bespectacled eyes. Giggling softly as she followed Lori out of the kitchen, Lyla just smiled back at Mike and made a funny face that seemed to say 'Hey, it's not my fault if I'm irresistible!' while she left the room and disappeared upstairs behind Lori.

Chuckling to himself, Mike retired to his own room to chill. Still determined not to let his sexy fantasies get the better of him, confident that he would get a chance to put his dick to good use soon enough, he sat at his computer and opted to distract himself with some gaming.

With his headset on and his eyes glued to the screen, chatting back and forth with his online friends as he got more and more immersed in shooting stuff all over the place, Mike took little notice of the time flying by. In fact, he got so involved in the game that he was genuinely startled when he felt a light tap on his shoulder. Removing his gaze from the screen for the fist time in over an hour, Mike was not at all prepared for what he saw as he slowly and distractedly turned to his right.

"Wha... Whoa! Holy shit, Lyla!"

Gloriously naked, standing right beside him while facing away, Lyla was arching her back and shaking her epic bubble-butt right in Mike's face, causing her big heavy tits to sway side to side as well. While she looked mischievously over her shoulder, Lyla couldn't help but giggle at her brother's awestruck, bug-eyed expression. In truth, the heavenly vision of his gorgeous sister's curvaceous body offered to him like that, and particularly her soft plump asscheeks rippling and jiggling mouth-wateringly mere inches from his slack-jawed mouth, sent a jolt of pure lust coursing through Mike's whole body, instantly making his cock stiffen to rock-hardness inside his pants and snapping him out of his gaming trance completely.

"Uhm, guys, I gotta go now... See ya..." Mike mumbled into his headset before taking it off and brusquely shutting down the computer, his head still turned to the side and his eyes utterly mesmerized by the bouncy, fleshy roundness of Lyla's fabulous ass.

Still smiling impishly over her shoulder and wiggling her ample rump in her brother's stunned face, Lyla purred: "Hey, Mikey... I could really use a big fat cock up my ass right now... Wanna help?"

"Wow, Lyla... Yeah, of course!" Mike groaned hoarsely, feeling his raging boner strain painfully inside his pants as his sister's teasing, irresistible words rang in his ears and sent his mind spinning.

Exhaling in delight as he placed his hands on the full curvy perfection of Lyla's big booty, immediately starting to caress her juicy buttcheeks with sincere reverence, Mike barely unglued his eyes from that masterpiece of an ass for a moment to meet his big sis's glinting, bespectacled gaze and put his lust-jumbled thoughts into words.

"Lyla, what exactly... I mean, not that I'm complaining or anything, all the opposite in fact, but, uhm... Do you really want me to fuck you in the ass? Like, right now, seriously?!"

Laughing as she enjoyed both her brother's kneading touch on her pillowy rump and the obvious horniness in his shaky voice, Lyla just shrugged and arched her back even more, pushing her beautifully round bubble-butt still closer to his face as she replied.

"Yep, I definitely want you to fuck my tight little asshole, Mikey! Lori did a great job licking my pussy in the last hour and she played with my butthole nicely too, but that's just not enough anymore... What can I say, Mikey, you made me into a total buttslut!" Lyla exhaled theatrically even as she shivered from the feel of her brother's lips making contact with her cushiony booty in a series of adoring smooches planted all over her soft, protruding meaty buns.

"Mikey, I really need your cock in my ass..." Lyla cooed wantonly as her brother kept paying homage to her majestic bubble-butt with kisses and caresses. "I've been thinking about it all day, you know... Look, I've even brought my own lube, since we finished yours last night!" she concluded with a giggle, raising the bottle of edible lubricant she held in her hand.

Massaging his sister's fantastic booty and sinking his fingers greedily into the plump roundness of her asscheeks, Mike felt his rock-hard cock flex powerfully inside his boxers, as if threatening to burst through his clothes at any moment. Still, as horny as he was, he still looked dubiously up into Lyla's eyes as he kept rubbing his face against her cushiony rump, tenderly nuzzling those big jiggly mounds and peppering their smooth surface with kisses.

"But what about Lori? And wait a second, Lyla... Did you come in here already naked? I don't see your clothes anywhere here, what the..."

"Mikey, relax!" Lyla interrupted him, rolling her eyes and tilting her plump ass up while pushing backward to smother his face with the soft thickness of her ample buttcheeks as she explained: "Lori won't bother us, I've tied her up to her bed."

"What!?" Mike exclaimed, half-laughing and half-shocked as removed his face from the mouthful of bouncy ass-flesh he was happily smooching. "You tied Lori up?! Jeez, Lyla, you didn't tell me you guys were into BDSM and stuff like that!"

"Actually, we're not. It was just a spur of the moment kind of thing!" Lyla giggled as Mike resumed kneading and caressing and planting adoring smooches all over her plump booty. "I came up with the idea of tying her up just because I wanted so bad to come here and get your big cock in my ass without Lori bothering us. I used some of her scarves and stuff like that, then I blindfolded her and kinda gagged her too, and then I went down on her for a bit. Before I left her there, I stuck a vibrator in her pussy and whispered into her ear that I wanted her to stay like that until I'd be back, and if she disobeyed me I wouldn't let her anywhere near my pussy for a week."

"Wow!" was all that Mike managed to say in response, too stunned to even keep up his ass-worshiping kisses and booty pawing massages.

"You know, I think Lori might be into that kind of stuff for real..." Lyla pensively went on. "She came super hard and super fast when I ate her out while she was tied up. And when I left her like that, all kind of helpless and face down with the vibrator still going in her pussy, I think she came again just from the final slap on the ass I gave her while I was getting out of her bed."

"Jesus, Lyla! You're fucking awesome... And badass, too!" Mike said, genuinely impressed by his big sister's effortless and seemingly boundless eroticism.

"Yeah, I guess I kinda am!" Lyla chuckled shrugging her shoulders, making her jutting tits sway heavily side to side. Then, placing the bottle of lube on Mike's desk and resting both hands on her luscious buttcheeks, she went on: "Look, I even prepped my ass for your big cock!

As his sister parted her big round asscheeks wide open for him, revealing the depths of her buttcrack, Mike gasped in awe at the cock-hardening sight she was offering him. Above Lyla's smooth nectar-glinting pussy, the tiny pink ring of her hineyhole was wrapped snugly around the jeweled base of a buttplug. Based on the oily sheen and the fruity smell exuding from the gummy rim of her sphincter, Mike correctly guessed that Lyla had already lubed up her anus, which testified to her determination to get sodomized and instantly amplified his libido by a thousandfold.

While his hands went to his bulging crotch and he started undoing his pants automatically as if through a sort of ass-craving trance, Mike exhaled with urgency and mumbled: "Holy shit, Lyla, that's just beautiful... Oh my god, I have to fuck you in the ass!" he declared, as serious as he was horny, looking straight into her smiling bespectacled eyes. "I just have to, Lyla... Like, right now, before I cum in my boxers or my dick rips through them! I'm so fucking hard for your perfect ass, sis, it's just so epic!"

Laughing throatily at her brother's lust-heavy compliments, Lyla swiftly turned around and dropped to her knees before him. Her huge boobs were swaying beautifully as she happily purred: "That's exactly what I was hoping to hear, Mikey!"
