As Madison Thorne knelt before her son, about to commit the incestuous act of taking his massive manhood into her mouth for the first time, she paused for a moment to think back on just how she'd wound up here on her knees before him.
It had started with a road trip to pick Billy up from college. Or, more specifically, the long ride home.
A ride complicated by the fact that her husband Lou had insisted on stopping at a yard sale on the way back to purchase an electric power jack, and further complicated by the fact that the only way to fit the contraption in their already cramped car was to fold down the front passenger seat and lay it across, leaving both Madison and Billy no option other than to ride together in the backseat, already overfilled with Billy's bags and belongings.
"Look," Lou had insisted when Madison objected, "it's only a ninety minute drive. It won't be that bad. But I couldn't pass that jack up, not at that price!"
And so with little choice, she'd squeezed into the car and situated herself on her son's lap.
Billy, to his credit, handled it with his usual, good natured charm. "Come on, Mom, it won't be that bad. I used to ride on your lap all the time as a kid. Now it's your turn I guess."
Inwardly she groaned, but offered what she hoped sounded like a lighthearted reply. "I suppose you're right. Just hope I'm not crushing you too much."
"Not at all," Billy grinned. "You're light as a feather."
"Oh, you're sweet," Madison laughed, "but I doubt that very much."
Madison was still in amazing shape for her age, it was true. Daily power walks and yoga had seen to that.
Still, she had trouble fitting her long, slender legs into the tight quarters, finally settling on positioning them wide to either side, causing the skirt of her short summer dress to ride up further than she was comfortable with.
With nowhere else for his arms to go, Billy wrapped them around her waist as she tried to maneuver her well rounded bottom into a comfortable position over him. It wasn't easy.
Madison tried to object one last time. "Lou, I don't know about this. Can't we strap that thing to the roof or something?"
"Oh, quit your bitching," Lou grumbled, "we'll be home before ya know it."
Forty minutes later, Madison was regretting not objecting more forcefully. Her legs were cramped, and every bump, every pothole, increased her discomfort.
But what was even more discomforting, and disconcerting, was the bump she felt beneath her.
Billy had dozed off about twenty minutes earlier. Madison still had to marvel at his ability to sleep during car rides, even in the most uncomfortable positions.
One part of him, however, was awake. And quite lively. And by the feel of it, quite huge.
Madison flushed as she felt it press up against her bum. She tried to shift herself off, but only made things worse as it wedged itself right into her ass crack.
"Of all the times for him to get a hardon," Madison thought. She couldn't spend the rest of the trip like this, not with that thing throbbing against her the whole time.
"Lou, my legs are cramped and I really need to pee. Can we pull over somewhere, please?"
"Oh, don't get your panties in a bunch, hun. There's a rest stop ten minutes up the road, we can stop there."
It wasn't her panties bunching up on her she was worried about. What bothered her was the moisture she felt forming in them. Because despite herself, the pressure from her son's raging erection combined with the vibrations of the car over the road was waking up her own sex organs.
Things escalated quickly when they hit a pothole. Madison bounced roughly, and as her butt dropped back down on her sleeping son, she was mortified to find his cock now nestled directly between her legs, pressed snug against her vulva.
Madison involuntarily shivered as her clit ground against it. She bit her lip to stifle her moan. "Jesus, this is so wrong. But my God, that feels good."
Turning as best she could, she checked on Billy. He still appeared fast asleep, his head lolling to one side.
Despite every instinct screaming at her about what a bad idea this was, Madison could not control herself. Her hips rocked slowly, subtlety, over his massive member, pushing her own throbbing sex downwards, her panties absorbing her drippings as she stimulated herself.
Madison fought to control her breathing; she wanted to moan, to squeal, to cry out in pleasure, but of course she could not.
Instead she pushed harder, her panties now deep inside her, the flesh of her outer labia parted and folded over the girth of her son like a hotdog bun.
Madison gritted her teeth as she felt the waves building inside her, but just before she crossed the threshold, Lou swung the car over to the offramp and pulled into the rest station.
Billy stirred beneath her. Throwing open the door, she scrambled to get out before he noticed the inappropriate position they were currently in.
With a quick tug at her skirt, Madison made a dash for the restroom.
In the stall, she yanked down her panties. She did indeed have to pee, but that wasn't the reason her panties were drenched. Her pussy was hot, swollen, dripping. Her piss came in a hard stream. The relief of her aching bladder was short-lived, however, because even the act of wiping herself clean sent shockwaves rippling through her.
Her fingers found her sex and quickly set about the task of relieving her pent up tension.
She came hard and fast, biting her lip to stifle her cries.
It wasn't enough. Her pussy still throbbed with unsatisfied need.
"This is nuts.I don't have time for this!" Madison started to pull up her panties but paused. They were drenched and sticky, and putting them back on over her already overstimulated pussy would be irritating and uncomfortable.
Pulling them off, she stuffed them in her purse, washed up and, with a deep breath to compose herself, exited the bathroom.
*****
Billy sat alone in the car, waiting for his parents to return. His mind raced with a multitude of conflicting thoughts.
He'd dozed off at some point during their ride home, but had woken up when the car hit a pothole, only to find, to his shock and horror, that he had a massive erection.
And his mother was sitting right on it!
Not just sitting on it, but grinding! Billy could feel her warm, soft, feminine flesh moving over him despite the layers of clothing between them. She was trying to be discreet, subtle, and yet her hips rocked steadily, making his cock throb and twitch beneath her.
Billy couldn't believe what was happening. He thought for a moment perhaps he was dreaming. But as her pace increased and her motions became more urgent, he realized this was no mere daydream.
His mother was actually dry humping him. And it felt fucking incredible.
Peeking out through his mostly closed eyelids, Billy watched the sway of her wide hips as she moved, enjoying just the hint of the creamy skin of her full, firm ass revealed from beneath her skirt as it rode up higher with her movements.
"Fuck, she's hot," Billy thought. "If she keeps this up much longer, she's gonna make me..."
His thoughts were interrupted as his dad swung the car off the highway into the rest stop parking lot.
Closing his eyes, he pretended to just be waking up as she jumped off his lap and out of the car.
Now he sat, his erection only slightly deflated and with a wet spot of precum staining his loose fitting gym shorts, wondering how he could possibly continue to hide from his mother that he was aware of what she'd been doing.
And how he could get her to continue.
Because as wrong as he knew it was, he wanted more.
*****
Madison arrived back at the car to find Billy still inside. Lou was still in the store, apparently purchasing snacks.
"Hey," she began tentatively, "didn't need to stretch your legs? I'm sure you must have been uncomfortable with me sitting on you all that time."
"Nah, I'm... I'm good." Billy blushed. "Fine. It wasn't uncomfortable. Barely noticed, really."
"I guess not, you slept like a log." Madison immediately regretted her choice of words as Billy's already crimson face flushed deeper. "Look, hun, if you want, maybe we can switch..."
She was interrupted as Lou rejoined them. "Alright, everyone's bladder empty? Let's get this show back on the road, still have a way to go and I wanna be home in time for the ballgame."
Reluctantly, Madison maneuvered herself back inside the car and onto her son's lap. His erection was less prominent at least, but she could still feel it there under her.
Back on the road, Madison did her best not to move as the car cruised along the highway. But every bump, every pothole, felt more pronounced, and soon enough her pussy was again aching with need.
Billy sat beneath her, every shift of her weight making him throb. Horrified, he felt himself stiffening to full erection.
Madison could ignore it no longer. Turning, she met her son's wide, frightened eyes.
"It's okay," she whispered, soft enough not to be heard by her husband, who had the radio playing, "it's not your fault. I know you can't help it."
Billy gulped but managed a smile. Facing forward, Madison shifted her hips and parted her legs slightly, freeing his swollen shaft enough to again press directly against her now bare cleft.
Billy felt her warm wetness already seeping into his cotton shorts. Emboldened by his mother's approval, he took her hips and helped guide her as she slid along his lengthy shaft.
"This is crazy," Madison thought wildly. "It was one thing to do this while he was sleeping, But now he's not only aware of what's going on, but actively participating! He's so fucking hard! I don't know how much more of this I can take! I need more!"
As if reading her mind, Billy slid one hand from her hip down to her thigh, caressing it for several long moments before slowly moving upwards under her skirt.
Madison stopped him just shy of the Promised Land. Turning to him, her eyes pleaded silently. "Don't do this."
Billy lowered his head in shame, pulling his hand back. Madison felt her own shame, not at what they'd been doing, but that he was obviously so eager to please her, and disappointed that she'd stopped him.
Madison caught his eye again. With a wicked grin, she lifted a finger to her lips. "Shhh."
Reaching between her legs, Madison found his shaft. Tugging at his loose fitting shorts, she freed it from the side leg hole.
His cock immediately sprung to full attention, now pressed directly against her naked feminine flesh.
"God, his cock is so hot, so hard, so fucking thick!" Madison felt the soft folds of her outer labia part over his girth, enveloping his shaft in a warm, sticky embrace.
Taking her hips, Billy again helped guide her as she slid along him, both now struggling to contain their moans. Fortunately, Lou had turned the radio up and was now singing along to some shitkicking country tune about girls and trucks and beer or some such nonsense.
Madison tensed as a short, sharp orgasm shook her, slicking her son's fat cock in yet more of her creamy juices.
The car bounced over another bump and suddenly she felt Billy's cock head poised right at the entrance to her now sopping wet cunt.
Madison froze. It would now take only the slightest movement to cross a boundary no mother should ever cross with her son.
Turning her head, she again gazed at her adoring son, so handsome, so desperately needy, his eyes wild with desire for her. A look she hadn't seen from her husband in many years.
"He wants this so badly. And frankly, so do I. But can I go through with it?"
The decision was made for her when the car took yet another bounce, and in that split second, his tip parted her swollen pussy lips and plunged inside.
Madison could not contain her cry of shock and pleasure.
"You okay back there?" Lou called over his shoulder. "Goddamn potholes! All the taxes I pay and they can't fix the fucking roads!"
"I'm... I'm fine," Madison managed. "Just a... leg cramp."
"Sorry, Mads," Lou chuckled, "hang in there, we'll be home soon enough."
The ride seemed to go on forever, although neither Madison nor Billy felt the discomfort of their awkward position anymore, far too absorbed in the forbidden pleasure of their secret coupling.
Wiggling her hips, Madison took more of him, slowly working his thick cock into her inch by abundant inch.
She wanted to ride it, to buck up and down on her son's cock like a cowgirl at a rodeo, but that would be far too obvious, and so she contented herself with swiveling her hips, grinding herself over it, feeling him pulse and throb against her vaginal walls.
Billy's grip tightened on her hips as she moved, his own body doing its best to meet her movements and push as deep as he could inside her.
She was so warm, so wet, so impossibly tight. His cock ached to release.
And then, with only a hint of a warning, it happened. Madison felt him swell up within her and ceased her movements, trying to stall it.
Billy clenched his groin muscles tight, trying in vain to hold it back. But it was far too late. Madison felt the rhythmic pulsing as Billy expelled his load, flooding her insides even as her silken walls clamped tightly over his shaft, now rippling with their own tremors as another orgasm raced through her.
Mother and son sat, trapped in a lover's vice, fighting every instinct to moan, to squeal, to cry out in ecstasy; struggling with all their strength not to move, not to thrust, not to rock the car any worse than it already was on its badly worn shocks.
Drained dry, Billy's cock refused to wilt inside her. Madison could feel his spunk oozing and clamped down tight against the leakage while covertly digging some wet wipes from her purse to stem the flow of damning evidence that could destroy her marriage and, potentially, her life if discovered.
Flushed, Madison turned to her son. Billy's eyes were wide with embarrassment and terror. His lips moved, forming silent words. "I'm so sorry, Mom."
Madison's heart hurt for him at that moment. He couldn't help his erection. But she certainly could have prevented what just happened instead of indulging her carnal desires.
Offering a comforting smile, she lay a finger across his lips. "Shush."
Billy relaxed at that, managing his own shy smile.
Grabbing a handful of wipes, Madison held them between her legs as she slipped Billy's finally deflated cock from her, catching the runoff with one hand while maneuvering his still thick, meaty organ back under his shorts.
They sat in awkward silence the rest of the trip, Lou oblivious to it all as he drove on, tapping out the rhythm to song after shitty song on the steering wheel.
Finally home, Madison dashed out of the car, not waiting for either of the men.
"Jesus, and I thought my bladder was bad," Lou grumbled as she departed. "Looks like it's just you and me, sport. Help your Old Man get this damn thing out of the car, will ya?"
Billy snapped out of his haze. "Huh? Oh, right. Sure thing, Dad."
*****
Finally alone, locked in the bathroom, Madison sat and wept.
"What have I done? I fucked my own son! My own flesh and blood! What kind of monster am I?"
Her spiraling thoughts were interrupted by a knock on the door. "Mom? That you? You okay in there? I heard you running up the stairs."
It was her daughter, Jenny. They'd left her home, knowing they'd need space in the car for Billy and his things, and she'd been more than happy not to have to take the trip anyway.
"I'm... I'm fine," Madison answered. "Just... It was a really long drive. I'll be out in a few, dear."
Composing herself, Madison stood and took a long, hard look at herself in the mirror. "I'm not a monster," she told herself. "Just a woman. A lonely, needy woman who made a mistake, that's all."
After giving herself a good wipe down to wash away the remains of her son's seed, Madison exited the bathroom and made her way to the bedroom. There, she changed her dress and put on a fresh pair of panties.
Again, she looked in the mirror. "It's fine. Everything will be fine. I'll have a little talk with Billy later. Explain to him what happened. Explain it'll never happen again; that we both need to forget about it and move on."
Steeling herself, she left the bedroom to head downstairs and rejoin her family. She was sure they were hungry and would be wanting dinner soon.
"Everything will be just fine."
*****
Later that evening, Madison crept quietly to Billy's door.
Lou was downstairs in the "Man Cave," with a twelve pack of Schlitz and a bag of pork rinds, watching the game. So she knew he wouldn't be heard from in at least a few hours.
Jenny, however, was in the bedroom next door. And Madison didn't want her aware of the visit to her son's room.
She knocked softly. "Billy? Can I come in, hun?"
"One minute, Mom!" Her son's surprise and nervousness was obvious. She could hear the sounds of the bed squeak as he apparently struggled with something, then silence.
"Um, okay, you can come in," he called.
Billy sat on his bed, blankets pulled up over his legs and lap, looking both frightened and guilty as she entered the room.
Closing the door behind her, Madison sat at the foot of the bed. "We need to talk."
Billy blushed bright red, his already wide, fearful eyes now welling up with tears. "Mom, I'm so sorry about... I didn't mean for..."
"Hush," she said softly. "It's okay, hun. It wasn't your fault. If anything, I should be the one apologizing to you. Because I'm your mother. And I should know better. I should have stopped it. Instead, I encouraged it. So the blame falls squarely on me. I just hope..."
Her voice trailed off, catching in her throat. "I just hope you don't hate me," she finally managed to croak.
"Oh, Mom, no! I could never hate you!" Billy moved forward to comfort her. Doing so shifted the blanket that had covered him, however, revealing what he'd been up to just before his mother had knocked.
Madison's heart fluttered when she saw his erection jutting out beneath his shorts. "Billy," she sighed, "that's really inappropriate. I should really..."
Billy rested a hand on her shoulder. "I'm sorry, Mom. But I can't help it. I've been thinking about it... about YOU... ever since we got home. I can still smell you on me, and it's been driving me crazy. I know it's wrong, but you just felt SO good!"
"It felt good for me too, hun," Madison admitted with a blush. "But you have to understand it was a mistake, right? That we can never do that again?"
Billy hung his head, dejected. "I understand. Doesn't mean I have to be happy about it."
"Oh, Billy, I'm so sorry, I never meant to put you in such a state." Madison put her arms around him, hugging him close.
Billy returned her hug, his arms finding their way around her lower back. Pulling her to him, her breasts crushed against his chest.
"Billy, I..." Madison couldn't finish her words. Instead, their lips met, and she was pushing him back on the bed.
Billy was already pulling at her top. Madison helped by pulling it up and over her head in one swift yank.
The bra came off next, her luscious breasts spilling free with a bounce. Billy's hands found them eagerly, her nipples already hard and swollen.
The screams of Madison's conscience became muted whispers, drowned out by her inner cry of pure lust.
A lust inflamed by the throbbing bulge she felt beneath her as she straddled her son, a bulge she set free with a tug at his shorts.
It was her first truly good look at it, and despite the fact she'd already had it inside her, she was both intimidated and excited by its size.
Her reflection on this was broken by her son flipping her off him over on her back. Swiftly he moved over her and wrested her terry cloth shorts from her hips, her panties coming off with them.
Billy moved between her legs then paused, taking in his mother's nude form as she lay below him, her mature beauty fully exposed and desperately needy.
He wanted to speak. To tell her how beautiful, how sexy she was. How the swell of her full breasts, the curve of her wide hips, the glistening sheen coating her flushed pink folds, made his heart race with passion and his cock throb with lust.
But he feared speaking anything at this point would break the spell, destroy the moment. So instead he grabbed her by the hips, flipping her over.
Taking his not so subtle hint, Madison maneuvered herself to her elbows and knees. Arching her back, she lifted her firm, round ass high, an invitation Billy readily accepted.
No foreplay was needed; she was more than wet enough. "Ohhh, FUCK!" Madison buried her face in the pillow in an attempt to muffle her ecstatic cry as her son plunged his massive member into her with one smooth thrust.
Taking her hips, Billy began to pump. Madison rocked in time with him, working her hips and ass to move with him, encouraging him to go faster, harder.
Reaching between her legs, Madison's fingers found her swollen clit and rubbed it furiously. Her brain had shut down at this point, and she acted on pure instinct; not thinking, only feeling.
Her first orgasm came quick and hard, again forcing her to stifle her cries in the pillow, yet still he thrust away within her, even as her cunt tightened and contracted around his thick girth, the sensation of it making him swell even more.
Madison could feel him expanding, hear his ragged breaths, signaling imminent release.
As much as she wanted it, a sudden pang of guilt struck her. The first time he'd cum in her had been an accident. This time, she had more control.
Reluctantly, she wiggled herself free of his cock. Turning to face him, she noted his shocked, sad expression.
One that quickly turned to wide eyed excitement as she took his gruel covered shaft in hand and guided it to her lips.
Madison locked eyes with him, kneeling before her on the bed, naked, sweaty, his cock covered in her slick, fragrant juices. In all her years, she never dreamed she'd be in this position with her own son, let alone be so eager to do what she was about to do.
Grinning wryly, she shook her head. Billy noticed it. "What are you thinking, Mom?"
Madison met his gaze again. "Just thinking how much you're gonna enjoy this." With that, her lips parted and she engulfed him.
Billy gasped with surprise and pleasure. He'd been with a few girls before, but none had ever deepthroated him like this. He could feel his mother's throat gripping him like a vice as she sucked, gulping and gagging until she finally came up for air, only to gobble him again, her nose buried in his neatly trimmed pubes, his balls pressed firmly against her chin.
It had been a long time since Madison had sucked a cock this big, and while she was excited to know she hadn't lost her touch, she also took a moment to wonder where Billy had gotten his monster size from; certainly not his father.
The cream she'd from left behind from her cunt mixed with her spit as she worked him expertly, one fist now tugging at his shaft in time with the suction from her mouth, while her other hand found his balls, rolling them around her palm, dragging her fingernails gently across his scrotum.
Again his cock swelled, in her throat this time. She could sense the rhythmic pulsing, feel his testicles tighten, signaling the release of their load.
Madison let go of her grip and again swallowed his length, just in time to catch the first blast of hot cum in the back of her throat.
Billy could barely stifle his howls as his mother's tongue folded itself along the underside of his throbbing shaft, her lips tight at the base, forming a seal as she sucked his erupting seed from him.
Madison gulped the seemingly endless stream flowing from him eagerly, until at last she'd drained him dry. Only then did he begin to wilt in her mouth.
Madison released him with a wet, sloppy plop. Licking her lips, she grinned up at her still panting son.
"Jesus, Mom," Billy gasped. "That was... "
"I know, honey, I know." Madison lifted herself and embraced him, her naked, sweaty breasts pressed firmly against his chest as she kissed him tenderly.
Breaking the kiss, she sighed. "I know when I came in here, it was to tell you we could never do this again. But now..."
Billy looked at her expectantly. "But now?"
Madison smiled up at him. "But now, I know just how good you feel inside me. And I haven't felt that good in a long, long time. So as long as you can keep a secret and your father doesn't find out, we can do this all summer long."
"Really?" Billy's eyes were wide, excited. "I'd love that, Mom. I love you."
"I love you too, Billy." Madison kissed him again before moving from the bed. "Now, I gotta get out of here before your father becomes suspicious."
Madison dressed and embraced Billy one last time. "Remember: this is our secret. But anytime THIS needs some relief..." Madison cupped his crotch in her hand for emphasis, "...you come see me. Mommy will make it all better, okay?"
*****
Jenny sat on her bed, ear to the wall. She'd been watching Tik Tok videos with her earpods in but had paused when she felt some strange thumps from the wall shake her bed.
She heard her brother's bed squeaking and at first just assumed he was jerking off.
Wouldn't be the first time she'd picked up on that. But this time was different. Because she was hearing voices. Specifically, a woman's voice. It was low, muffled, but she could hear the moans distinctly.
"He must be watching porn and didn't bother with headphones," she thought.
But then the noises subsided. Then soft voices, barely discernible.
And then she heard his bedroom door open, and the padding of footsteps as they made their way downstairs.
Jenny jumped from her bed and threw open her door, but whoever had left Billy's room was already well out of sight.
"He hasn't been home for a full day, how is he sneaking a girl into his room already?" Jenny wondered. "And how did she get past Mom on the way out?"
Closing her door, Jenny returned to her bed. There was a mystery here, that was certain.
A mystery she intended to get to the bottom of.
Billy, you up?" Madison rapped gently at her son's bedroom door, only for it to swing open.
Billy stood naked in front of his full length mirror, absently stroking his massive cock. Totally absorbed in his self pleasure, he didn't notice his mother, peeking her head around the partially opened door.
Madison simply admired him for a few moments; tall, muscular, tanned, and oh so well hung. She'd become well acquainted with his cock in the past few days since Billy had returned home from college, mostly especially on that life changing ride home where she'd been obliged to sit on his lap.
After an initial bout of guilt, Madison had given in and accepted her carnal desire. Much to her perpetually horny son's delight.
After a quick look over her shoulder to make sure no one else saw her, Madison quietly pushed the door the rest of the way open.
"Ahem."
Billy jumped, his cock jumping with him, as he finally noticed his mother standing in his bedroom doorway. Her long, wet hair cascaded over her shoulders, spilling into the ample cleavage displayed by the very loosely tied bathrobe she wore. Her dark eyes shone with a mix of curiosity and excitement. Her lips twisted in a strange yet alluring smile.
"My God, but she's sexy, my mother or not." he thought.
Closing the door behind her, Madison entered the room, the tie of her robe coming undone as she moved towards him. Her full, natural breasts bounced with each step until all but the nipples were revealed.
Billy instinctively moved to cover himself, then realized he was being ridiculous. His mother's eyes flicked down to his pulsing member as she paused mere inches from him. She smelled of bath soap and body lotion.
Madison chewed at her lower lip softly. "Now Billy, what did we talk about? After that first night?"
Billy could hardly contain himself as she moved still closer, close enough that his throbbing erection was now firmly pressed to his mother's bare abdomen.
"What I said was, anytime THIS needs some relief..." Madison gripped his shaft firmly for emphasis, "...you come see me, and Mommy will make it all better."
Despite his excitement, Billy still worried. "But... what about Dad? Where...?"
Madison shushed him. "Your father is outside, mowing the lawn, getting the yard ready for your sister's birthday / graduation party. And Jenny's still sleeping in her room; I checked before I came here."
Sliding down him, Madison dropped to her knees. Looking up into his eyes, she licked her lips eagerly. "Relax, hun. Not like this is the first time your mother has had to relieve your excitement."
Billy's hands found her head, running his fingers through her still damp curls. "I'm sorry for jerking off without you, Mom. I should have remembered no one takes care of me like you do."
Madison smiled warmly. "It's okay, sweetie. I'll always be here to remind you." With that, her lips wrapped around him, and with barely a gulp or gag, she swallowed him to the hilt.
"Ohhhh, fuck!"
Billy's body trembled, every nerve ending on fire as Mom worked her magic, sliding up and down his cock with graceful ease. Full, lush lips worked in tandem with slippery tongue, vibrations from the back of her throat sending shivers up his spine as she hummed merrily with her efforts.
But it was those eyes, those dark eyes, boring into his soul, that truly stirred his lust. They were the eyes of both a MOTHER who took pride in her son, and a woman, a LOVER who took great delight in giving pleasure with her mouth.
Again and again Madison brought him to the brink, only to pull back and release him with a sloppy plop, running her tongue over the swollen head of his cock while swirling it around her soft wet lips in small, slow circles, her hand gripping his base tightly, holding back the impending storm.
Sensing he could take no more, she again engulfed him, her nose buried in his pubes, holding her position as he swelled and finally released his load deep into her eager throat. Madison swallowed reflexively, sucking hard on his shaft, drawing out every last drop before releasing him with a satisfied sigh.
A mix of spit and cum dribbled down her chin as she grinned up at him. "Feel better, sweetie?"
"Oh, fuck yes," Billy gasped, still wracked in the aftershocks of his quake-like orgasm.
"Good boy." Madison stood and slipped her robe back on, but left it untied, giving Billy a good look at her mature, sexy body. "Maybe later tonight, you can return the favor. But for now, you need to get out there and help your father. But first..."
Madison's nose wrinkled as she sniffed at him. "...go take a shower, young man!"
"Aw, mom," Billy pouted, "What's the point if I'm just gonna go work up a sweat again helping Dad?"
"Because I can't risk your father catching even a whiff of my perfume on you," Madison said sternly. "No, go, wash up then get out there."
Madison turned and swiftly exited the room, leaving her son standing there still naked and semi erect.
Snapping out of his post orgasmic daze, Billy decided to obey his mother's directive. He opened the door and had almost stepped out into the hall when he remembered he was still nude. A quick search found the bath towel he'd left strewn over his closet door the other day. Covering himself, he again made for the bathroom.
His progress down the hall was cut short when his sister, Jenny, suddenly exited her own bedroom, almost plowing into him. "Where're you headed off to in such a rush?"
Ignoring her, Billy attempted to go around, but she moved in front of him, blocking his path. Despite himself, he couldn't help but notice how the tank top and tight boy shorts she called "sleepwear" clung to her petite but curvy frame. Or how the top hung so low on her that he could make out the edge of her areola peeking out from under it.
Remembering he was only in a towel, he quickly averted his eyes and tried to slow his quickened pulse.
Jenny focused on him with suspicion. "Was that Mom I heard leaving your room a minute ago? It was, wasn't it?"
"Um, yeah, she was just... reminding me to... go help Dad set everything up for your party."
Jenny's eyes were almost as fiery as her hair. "She was in there an awful long time. In only her bathrobe. And now here you are, all flushed and with a semi poking up under your towel."
Billy tried to cover the bulge with his hands as he again made to move around her. "Jesus, Jenny, gimme a break! Haven't you ever heard of morning wood?"
As Billy slammed the bathroom door, Jenny called out, "Yeah just make sure to take care of that thing before my party! I don't need you walking around the pool with a hard-on all day, gawking at my friends!"
Jenny made for her bedroom door, then turned back again. "And don't cum in the shower, you gross fucking pig! I gotta use that thing too ya know!"
***
Jenny sat on the edge of her bed, her mind and body a whirlwind of emotions.
Something was UP between Billy and her mom, she just knew it. What she didn't know was exactly WHAT. It wasn't just Mom's covert visits to his room, either late at night or early morning, but the way they'd been looking at each other across the room or the kitchen table when they thought she wasn't looking.
Mom was also wearing sexier outfits around the house lately... tight tops with plenty of cleavage, short shorts with her ass hanging out.... and meanwhile Billy was a walking hard-on.
And what a hard-on it was, apparently. Jenny sighed in frustrated confusion. She'd turned 18 two months ago, (they had waited to combine her birthday with her graduation party,) and would be off to college herself in the fall.
She had really been hoping to lose her virginity and get some experience under her belt before then. Yet despite being pretty, and very popular, the guys at her school tended to avoid her.
Jenny could only imagine one reason: they were afraid of her Big Brother coming home from college and kicking their asses. After all, it couldn't possibly be her personality, right? She couldn't help it if she was the only charming and intelligent person in a school, hell an entire town, full of pathetic miscreants.
Throwing herself back on the bed, her hand found its way between her legs, attempting to soothe the dull ache she found there. There was only one solution of course, and Jenny threw off her pajama shorts a
with a sigh of both arousal and frustration.
She wanted more than just her fingers, or the handle of the hairbrush she quickly grabbed off her nightstand. She wanted cock. She wanted to get laid. Or at least get SOME experience before she went off to college.
Jenny's fingers became sticky as she explored the flushed folds of her virgin pussy. Despite her best efforts to conjure up the mental image of some Handsome Dream Hunk making her his, her mind instead kept returning to that image of her brother Billy, standing there in nothing but a towel that struggled to conceal his erection.
And what an erection it was. Even hidden beneath the towel, Jenny had clearly seen the outline of it; the long, thick shaft, the round, bulbous head.
In her mind's eye, Billy drops the towel, revealing himself fully to her. "Do you like what you see, Sis?"
Jenny drops to her knees before him, eyes wide, her mouth salivating as she comes face to face with it. Her hand shakes as she reaches out, grips it, her fingers barely closing around its girth.
She licks her lips, then parts them, closing her eyes as she guides the tip to her warm mouth. Her tongue darts out with an exploratory lick, tasting the drop of precum she finds there. Relaxing her jaw, she opens wider to accommodate him.
She slowly swallows him, inch by inch, her clit pulsing with excitement in her now soaked panties, pulsing and pounding and...
"Jenny!" Her mother pounded again on her bedroom door. "You awake, sweetheart? Come on, get up! You promised you'd help me with the food for your party!"
"Dammit!" Jenny grumbled. "Talk about a mood killer."
Louder, she called out in answer to her mother. "Yes, Mom, I'm up! Just, um... give me a few minutes. I'll be right down!"
As her mother's footsteps receded back down the stairs, Jenny's fingers again found her slick pussy. But the bubble had burst, her fantasy intruded upon by harsh reality, and, at least for the moment, she was no longer in the mood.
Still, as she exited her room and heard the shower running in the bathroom, her thoughts again turned to her brother, gloriously naked and probably jacking that huge cock, just behind the bathroom door.
With a final, frustrated sigh, she shook off the image and made her way downstairs.
***
The party had been going for several hours, and Billy decided he simply couldn't take it anymore. Despite the blowjob his mother had given him that morning, his cock throbbed in his swimsuit as he watched Jenny and her friends frolicking in the pool. It wasn't his fault though, he rationalized to himself. After all, how could he not be turned on by the sight of half a dozen teenage girls, each hotter than the next, running around in skimpy bikinis all afternoon?
He had thought about asking his mother to help him out, maybe sneak off to his bedroom and give him another blowjob, or better yet, let him pound out a quickie.
But she'd been swamped with hostess duties; serving the food, cleaning up behind the messy girls, etc. His father was manning the grill, yes, but all the other duties had been left to his mom.
And so Billy stood from his lounge chair, trying desperately to look nonchalant even as his hands attempted to casually cover the bulge in his trunks, and made his way inside the house.
Instead of going up to his room, Billy instead made a beeline towards the guest bathroom on the ground floor. The window overlooked the backyard and so of course gave him a perfect view of the girls.
His cock went from half mast to full in the space of time it took him to free it and take it in hand, pumping away as he peeked out through the blinds.
He couldn't decide which girl to focus on, they all looked so fucking hot. There was Tina, the tall, curvy brunette with the bronze summer tan and needlepoint nipples poking out from her top. Then there was Sofia, the chunky Latina with the incredibly round ass.
There was Candi, the petite blonde with the perfect tits from next door, wearing probably the skimpiest bikini. Even from a distance Billy was sure he could still see the edges of her areola sneaking past the tortilla chip sized cups of her top.
And those were just the hottest of Jenny's friends. Even Giana, the obligatory frumpy, book-wormish one, looked fuckable enough in her relatively modest yet still form fitting one piece.
Billy stroked madly at his cock as his eyes darted from girl to girl, imagining each one naked, on their knees, begging for the cum boiling within his balls, ready to unload on their eager upturned faces...
Just as he was about to explode, the bathroom door flew open. Billy turned to find his sister standing there, her face a mix of shock and anger.
"Billy? What the actual fuck???"
***
Despite her 'masturbation interruptus' earlier, and having to spend most of the morning in the hot kitchen with Mom, Jenny had managed to relax and enjoy herself once the party had begun.
That is, until Billy had made his Grand Entrance. His obvious gawking immediately annoyed her. How dare he come out here just to oogle her friends?
Worse, he never once looked HER way. Jenny knew she couldn't compete with some of her friends in the looks or body department. But still, she looked pretty darn sexy in this bikini, so why hadn't he even noticed?
Jenny shook these thoughts from her head with a grimace. Why was she MAD her brother wasn't looking? He's not SUPPOSED to get aroused by his own sister, no matter how skimpy or revealing her outfit!
Speaking of aroused, Jenny also easily spotted the tent in his trunks. So did her friends, producing silent smirks and eyerolls knowingly exchanged between them.
When Billy had finally left the pool to head inside, Jenny decided to follow him to give her a piece of her mind. She gave him a few moments to get inside so it wouldn't be obvious she was following him, then headed in herself.
She went upstairs to his room and was confused when he wasn't there. The bathroom door was open as she went by so he certainly wasn't there either.
Heading back downstairs, she realized he must have just ducked into the guest bathroom. She was about to knock when she heard the sound of what could only be heavy breathing.
Leaning her ear to the door, she jolted when it swung open just a crack. Apparently Billy, in his haste, hadn't closed it all the way.
Peeking in, Jenny's jaw dropped at the sight that greeted her: Her brother, bare assed and facing the window, his right arm a flurry of motion as he moaned steadily.
'Oh my fucking God, he's jerking off!' Jenny thought wildly. She had a moment of frustration at not being able to actually see his dick, a moment that quickly turned to anger when she realized why he was facing the window.
Jenny threw the door open wide. "You fucking perv!"
Panicked, Billy instinctively turned towards her, which of course only made the situation worse as he was now completely exposed to her. He was also right on the edge, and the shock of being caught caused him to lose control.
Jenny's eyes bulged as his cock twitched wildly, launching stream after endless stream of thick cum all over the bathroom floor. Jenny wasn't completely naive, she'd watched porn before. But she'd always thought both the cock sizes and quantity of ejaculate they expelled exaggerated.
And yet here was Billy, her own brother, standing there shooting spunk from his prodigious penis like a high pressure sprinkler system.
Billy, shocked, managed to find his voice. "Jenny? What the fuck??? Get the fuck out of here, Jesus!"
Instead of leaving, Jenny closed the door behind her. "Why? So you can keep jerking off looking at my friends in their swimsuits, you fucking pig? Just wait til I tell Mom what you were up to! And my friends! They're gonna be so pissed. You'll never live this down."
"Jenny, please, don't!" Billy struggled to put his cock away as he pleaded, but despite his horrific embarrassment at having just blown his load in front of his sister, his erection refused to subside. "Please, don't tell anyone! I'll do anything you want! Do your chores all summer, drive you to the mall, whatever you want. Just please, I'm begging you, don't tell anyone, especially Mom!"
Jenny stroked her chin thoughtfully. She hadn't even considered blackmailing him until he'd brought it up. But obviously this was a situation she could certainly take advantage of.
Her eyes never left his still rigid member as she answered. "ANYTHING I want, eh? Fine. Come to my room tonight, after everyone has gone to bed. I'm sure we can work something out."
Jenny turned to go, then paused. "And clean that mess up, for fuck's sake! My friends are gonna use this bathroom, nobody wants your disgusting sperm all over them, sheesh."
As Jenny closed the door, she let out a deep sigh. Her knees almost buckled but she managed to keep her feet. She couldn't believe how fucking HORNY that had made her. After all, what sister would expect to get turned on by the sight of her brother's cock?
Jenny could feel how wet she was, how HOT. She couldn't go back out to the pool like this. She needed some relief.
She was halfway up the stairs when she heard her mother behind her. "Jenny? You okay, sweetie? Your friends were all wondering where you went."
Jenny paused on the stairs but didn't turn back, afraid her mother might notice her flushed chest and rock hard nipples. "I'm fine, Mom. Feeling a little queasy, though. I think Dad may have undercooked the burgers. Just gonna go lay down for a few."
"Oh, honey, I'm sorry," said Madison. "I'll go talk to him. You need me to bring you anything?"
"No!" Jenny answered, a little too forcefully. "I'm okay, really. Just need to, um... rest."
"Okay, well you call me if you need anything, hun."
Jenny started moving again, but then had a wicked thought.
"Hey, Mom? You may wanna check on Billy. He's been in the downstairs bathroom awhile now, he might be sick too."
***
Billy stood at the door to his sister's bedroom, shifting on his feet nervously. It was late, the party had ended hours ago and his parents had gone to bed.
Jenny had texted him shortly after: "Don't forget. My room. Now."
Billy couldn't help but wonder what she would demand of him that required this clandestine meeting so late at night.
His question was answered when he entered her room. Jenny lay sprawled on her bed, wearing only a sheer negligee that did little to conceal her petite body.
"It's about time, Big Brother." Jenny winked at him. "I'd thought you'd forgotten about our deal and that I might have to go wake up Mom to tell her what I caught you doing earlier."
It took several moments for Billy to get his brain engaged enough to respond. "Look, Jenny, I'm sorry about perving on your friends, I really am. But I don't see what this..."
He again lost the function of speech as his sister casually lifted the negligee up and off, fully revealing herself to him. "What THIS is is me getting a little experience with the male anatomy before going off to college, and YOU, Big Brother, are going to help me."
Billy was torn. It was one thing to be secretly fucking his own mother. But now, his sweet, innocent little sister suddenly wanted him too? Nothing good could possibly come from this, and yet he couldn't deny the throbbing erection already forming in his pants.
Jenny noticed it too. "I knew it wouldn't take much to convince you. Now bring that damn thing closer, I've been dreaming about getting a better look at it all day."
As Billy approached the bed, Jenny sat up and moved to the edge of it. Billy stopped directly in front of her, and Jenny found herself now face to bulge with her brother's erection.
Jenny suddenly felt... well, a mix of emotions, all at once, like clothes tumbling in the dryer.
She was excited, for sure, her pussy already swollen and wet. But she was also nervous. For all her bravado, she'd never done this before. She also felt quite intimidated by the size of the beast currently struggling to free itself from its cloth prison just inches from her flushed, freckled face.
Billy noticed her hesitation. "Hey, it's okay. You don't have to do this if you don't want to, you know."
"No, I want to." Taking a deep breath Jenny found her resolve. Reaching out, she found the snap to his shorts, then the zipper. "You just might have to, um, coach me as we go. I mean, I've seen porn of course, but I always assumed most of what they do is... exaggerated."
Billy laughed kindly. "Oh, for sure. Trust me, I've been with a few girls at college, and trust me, none of them ever came close to sucking or fucking like they do in porn. In fact only Mo...ummm, one ever managed to deep throat me all the way."
Jenny tugged at her brother's briefs, his cock jumping out like a coiled spring suddenly released. Her eyes went wide at her first good, up close look at it. "I can see why most girls would, um, struggle with that. I think I'll start slow. Just, um...."
Her voice trailed off. She hated this sudden feeling of insecurity, of not knowing what she was doing. She wanted to be strong, take charge, show her brother SHE was in charge.
Taking his huge phallus in hand, she marveled at the heat of it, the pulse, throbbing in her palm. Billy was already groaning in pleasure and she'd barely even touched him. Jenny had a sudden revelation as the first drop of precum made an appearance from his swollen purple tip. She WAS in charge. Experienced or not, he was already putty in her hand.
Well, his cock wasn't putty, certainly, more like concrete or better yet, ceramic. But she instantly knew the power she now had over him with one simple touch.
Looking up, she gave him a wry, almost evil grin. "Just relax, Billy Boy. I may be inexperienced, but I think I know enough to rock your world."
With that she brought her lips to his head. Parting them, she slowly, gently, sucked him into her mouth. Her jaw strained to accommodate his girth, but within moments she had what felt like at least a good four, maybe five inches inside.
Billy's groans became gasps. "Oh, fuck!"
Breathing through her nose, Jenny began slowly, bobbing her head in steady rhythm, sucking at the frenulum and neck of his glans while her hand kept a tight grip at the root of his shaft. Drool ran from the sides of her lips on each withdrawal, already making a mess, but that was okay, she knew guys liked that.
She also knew they liked the soft gurgling noises she made as she continued to work his shaft deeper into her throat with each downward thrust. To her surprise, she didn't gag until the halfway point.
Jenny reflexively pulled back, sputtering spit bubbles as she caught her breath. "Jesus fucking Christ this thing is massive! I can't even imagine trying to fit this python in my pussy!"
Billy's voice trembled as he managed to reply, "It's... not as bad as you'd... think, you just have to... go slow."
Jenny took a fresh grip on her brother's cock, two hands this time. "Yeah, well, I don't think we'll be going quite that far tonight. For now, I just wanna..."
Jenny again engulfed him, deep as she could. She held there long enough to again establish breath control through her nose before continuing her blowjob in earnest.
Billy's legs shook as his sister threw every trick she'd learned watching porn at him; twirling tongue, sloppy sucking, her hand a slippery spit covered blur tugging at the lower half she couldn't fit past her over extended jaw.
Billy couldn't believe what a little tigress she was. What Jenny lacked in experience, she certainly made up for in enthusiasm, and Billy couldn't help thinking that, with a little time and practice, Jenny could be just as good a cocksucker as his mother.
The thought of Mom made his balls swell and Billy soon felt the familiar tingles deep within that signaled his pending release.
"Jenny, I'm...oh, fuck, I'm close! Like, really close! You might wanna..."
Jenny heard his warning but didn't slow her pace. She was determined to see this through, to take his load, to swallow every drop.
A determination that quickly faded as the first blast erupted in her throat. Jenny gagged and choked on the river of cum clogging her windpipe. Her survival instincts kicked in and she pulled back off his cock, just in time to catch the second blast across her face.
Despite her disorientation, Jenny managed to keep the hand she'd been stroking him with moving as Billy continued to ejaculate a wild, voluminous amount all over her face, breasts and stomach. She could feel it in her hair, and a massive blob dripping off her right ear.
"Jesus Christ, Billy, how much...?" Her voice cut off as yet another jet splattered on her lips. Her tongue lapped at it instinctively. It didn't taste as bad as she expected, but she wasn't thrilled about the texture.
Recovering from her initial shock, Jenny took his still leaking head between her lips and continued to suck her brother dry, now more easily able to swallow the remaining, less powerful spurts.
Releasing him with a final wet, sloppy plop, Jenny grinned up at him proudly as she wiped his spunk from her lips and chin.
Billy's face was bright red as he struggled to catch his breath; he'd had to clamp a hand over his mouth to stifle his howls, and yet he still worried the entire neighborhood had heard him.
Turns out, only one other person had.
"Billy? Jenny???"
The siblings turned as one to spy their mother, standing in the bedroom doorway, hands on her hips, her face incredulous.
"Mom???" Billy stumbled back, away from his naked, cum covered sister, only barely managing to keep his feet as he struggled to adjust his shorts. "I'm so sorry! I didn't mean for this to happen! Just let me..."
"Save it, young man," his mother cut him off sternly.
Turning to her daughter, Madison glared down at her. "And you! What kind of botched ending was that? You have to relax your throat, sweetie. Close off your trachea, get it to flow down the esophagus, otherwise you could choke to death!"
Jenny and Billy looked at each other with confusion, then turned their faces back towards their mother. "Um... what???"
Stepping fully into the room, Madison closed the door behind her.
Sighing, she slipped off her bathrobe, revealing her fully nude body. "Guess I gotta teach you two how to do EVERYTHING."
