On All Fours

Your head jerks up and you lock eyes with Lisa. She stands upright, her hands on her hips, staring down at you with a hungry expression on her face. Your sisters let out teasing 'Oooooohs', grinning from ear to ear as they watch the evening take a turn everyone sort of anticipated anyway.

You gaze into your mother's eyes, and an unspoken communication passes between you in a second. A raised eyebrow. A minute tilt of the head. An almost imperceptible shrug.

Both of you are sober enough. Both of you want it. And both of you are fine with saying so in front of Sarah and Crystal. You've laid bare your relationship to each other for them already, there is nothing left to hide anymore.

You slowly push your chair back and get to your feet, never breaking eye contact with Lisa. Sarah, beer bottle in hand, hollers with delight. Lisa turns to leave, but you have another idea.

"Alright, girls, it was fun. See you tomorr-"

Her words cut off as you continue your upward motion, lifting your left knee up and hoisting yourself onto the table in one smooth motion, making it groan softly under your weight. Three speechless faces stare at you as you crawl to the middle of the table naked, facing Lisa. Your elbows touch the table, cushioned by the gathered clothes there, and your chin rests on your clasped hands. A smug smile tugs at the corners of your mouth. Your ass is the highest part of you, jutting out lewdly and invitingly behind you.

"Come and get it, Mom."

You hear Sarah and Crystal inhale sharply, but your eyes are locked on Lisa's, waiting for her reaction. She raises her eyebrows one last time, a question. You answer by opening your mouth as wide as possible, extending your tongue as far as it will go, and giving her your best come hither look. She doesn't need any more encouragement than that.

She reaches down and hoists her massive member up, using her hands to lift it towards your lips. The fat bulbous head bounces against your lower lip, and your tongue peeks out from between them, tasting its musky sweetness. With a low grunt, Lisa pushes forward, sliding her soft cock past your lips and into your warm, wet mouth. You wrap your lips around her shaft and suck gently, your tongue playing along the underside of her throbbing meat, drawing out a shuddering breath from her.

"Holy shit..." Crystal mutters from somewhere behind you.

Lisa closes her eyes, savoring the feeling of her son's talented mouth on her dick. Your tongue dances around her cockhead, lapping at her precum eagerly. She looks down at you with a smile on her face, her fingers weaving through your hair. She caresses the back of your head, her touch tender, loving, yet firm at the same time. Her cock grows bigger with every passing moment, swelling in your mouth, starting to stretch your lips apart. You worship the tip with your tongue, swirling it around and pushing it into her urethra.

"Mmhh... he's just the best," she moans softly, her hand massaging the back of your head gently. "So soft... And so eager..."

Your ears pick up the laborious breaths of your sisters behind you, with the distinct sound of fapping filling the air. They are masturbating while watching you, stroking their dicks furiously to the sight of you kneeling on the table and sucking on your mother's gigantic cock. Knowing they are jacking off, getting hornier and hotter by the second, only turns you on more.

Under your tender ministrations, Lisa's cock grows harder by the second, swelling and hardening, until it finally reaches its full length, veins popping out all over the surface. You look up at her, never taking the crown of her cock out of your mouth for even a second, and make eye contact with her. Her chest is rising and falling rapidly now, her breath coming in ragged bursts. A thin layer of sweat covers her body, glistening in the light of a nearby lamp.

You take one hand off the table and place it on her hip, feeling her hot skin against your palm. With a slight push, the other hand leaves the table and comes to rest on her other hip. Your arms are stretched out, holding yourself up with the support of your mother's hips, her massive cock connecting your bodies like an iron bar.

"Is he... Sis! He's gonna do it!" Crystal whispers to Sarah, whose breathing is labored as well.

"Hnnghh... Fuck yeah, he is." Sarah growls, her voice trembling with excitement, beating her meat furiously to the sight before her. "He's so fucking good at this!"

Lisa takes her hands off your head entirely, and starts to play with her heaving tits instead, pinching and rolling her nipples between her fingers, pulling on them firmly. She groans, throws her head back, and grunts in pleasure.

Then, with both arms, you start pulling her in. Her massive cockhead leaves your caressing tongue behind and reaches the entrance of your throat. You take one last breath through your nose, look up at Lisa, and give her a wink. And pull.

"Aaaaaahhh...!!" Lisa moans loudly, throwing her head back as far as she can.

"Fuck! Look!" Sarah exclaims, barely audible through the sound of wet slapping flesh. "He's doing it! Oh my god, he's eating her dick!"

The fat shaft pops into your throat, making you gag softly around it. Lisa's knees buckle slightly at the sensation, but you hold on tight, not letting go of her hips. Your tongue slides along her throbbing length, massaging the sensitive underside of her cock, trying to find her most erogenous zones. You're rewarded by a soft, mewling whimper escaping Lisa's lips.

Your neck bulges lewdly as the mammoth member slips further and further down, and a strangled gasp escapes Crystal's mouth in response. Her hips are thrusting forward, her hands are stroking her cock vigorously, and she explodes with a loud groan. Thick strands of jizz spurt from the tip of her member and hit your thigh, oozing out slowly in a messy trail as it runs down your leg.

"Doug gnnnghh... Fuck... Fuuuck...!" Crystal whines, jerking her cock desperately, covering your lower calves in thick white ropes of cum. It feels hot and sticky on your skin, adding to the lustful atmosphere. "How are you so fucking sexy...?!" She keeps going for a while, her balls emptying themselves over you, until she finally collapses on her chair, breathing heavily. Her chest rises and falls rapidly, sweat beading on her forehead. She never stops stroking herself though, eyes glued to your ass.

You feel powerful. Aroused. Horny as fuck. Kneeling on the table naked, with Lisa's pulsating cock in your throat and your sisters jerking off to you, you couldn't be more turned on. You reach further back with one hand and pull her butt towards you, spearing your throat on her huge cock even deeper.

"Oh, fuuuuck..." Lisa moans deeply, closing her eyes and losing herself in the pleasure. "Yes... Yes... Take it all... Gnnnghh... Oh god... Fuck, yes..."

"Goddamn, bro... How the hell...?!" Sarah mumbles through gasps, watching you with wide eyes, jacking off at a fever pitch now.

With a last shove, you push Lisa's massive dick down your throat, forcing your head down onto her pelvis, taking every inch of her fat length inside of you. Your throat bulges obscenely around her cock, lips pressed tightly against her root, cheeks hollowing out as you suck greedily at the massive meatpole in your mouth.

"My god, he took it all! He's deep-throating Mom! Nnnghh!!" Sarah cries out, her words slurring together in an incoherent mess, her fist a blur on her cock. With a shrill cry, she cums hard, painting your body from the other side with another layer of thick cum. She strokes her dick vigorously, milking out every last drop of jizz.

Your arms lock behind Lisa's back, holding you up in place, as the entire length of her huge rod fills your pulsating throat so deliciously. This is where you belong. This is your purpose. Your lips are stretched to their limits around her thick cock, a strand of saliva dripping from the corner of your mouth, coating the surface of her member in a shining film of spit. The taste of her precum coats your tongue, filling your senses. She thrusts shallowly into your throat, enjoying the feeling of your muscles squeezing around her, milking her shaft, trying to drain her of everything she has to offer.

"Oh fuck... oh fuck, Doug... I can't take it anymore... You are so good... You are amazing... You are... Unfh... Aaaaahhhh..." Lisa moans, her hips shuddering as she pushes herself closer to the edge, her voice breaking up into a high-pitched whine as her balls clench painfully, drawing up towards her body. "I... Aaaaaaahhhhh!"

You feel her cock swell inside your mouth, the girth growing thicker and harder than before. Her balls tighten against her thighs, and then, with a loud wail, she explodes inside of you. Her cock throbs mightily, and thick streams of spunk erupt from her pisshole like a fountain, pumping straight into your belly. You keep your lips wrapped around her cock tightly, swallowing everything she gives you, your throat bulging obscenely with every load.

"Holy fucking shit... That is hot!" Crystal groans, stroking herself furiously again.

Lisa's hands find your face again and she grabs hold of your head, keeping it firmly in place. You feel her cock pulsate inside you as it shoots its load over and over again, her balls emptying themselves into your stomach with abandon. It's overwhelming, intoxicating, addicting. You want more. You need more. Your mind turns blank as the ecstasy washes over you, pleasure radiating outwards from the base of your spine and setting your nerves alight. From your cage, your own load spurts out onto the table, adding to the sticky mess.

Your sisters watch you with lust-filled eyes, mouths agape, completely spellbound by the sight of you taking on such an enormous load. You continue sucking Lisa off through her entire orgasm, until her last drops run out and she slides out of your throat slowly. Your lips cling to the tip, but eventually part ways as she pulls out entirely, leaving your tongue hanging out lewdly, coated in a thick layer of jizz.

After a few heavy breaths, tasting the remnants of your mother's delicious cum on your tongue, you glance back to your sisters. They stare at you with flushed faces and swollen cocks in their hands. Sarah's hair sticks to her sweaty forehead, and her chest rises and falls rapidly. Crystal's eyes are wide open, staring at you intently, her entire upper body blushing, with nipples as hard as diamonds. They look... cute. Hot. Overwhelmed.

Lisa is the first to break the silence. In between heavy breaths, she whispers softly.

"Thanks, sweetie.... You were amazing... as always. Hey, girls? Do us a favor?" She asks with a smile.

"Y-yeah. Sure," Crystal replies hoarsely, nodding eagerly.

"Absolutely," Sarah adds, equally breathless.

"Could you help your brother turn over? On his back, butt towards me?" Lisa continues, stroking your face gently.
