May Watches

May (14yo) comes home early to see something she shouldn't...

Stan shoved his bike into the storage shed in the corner of the garden, grinning as he flexed his arms. The doctor had cleared him for "normal activities" last week, after weeks of physio following the removal of his casts—not that he'd waited for permission to test his limits. He could lift May clear off the ground now if he wanted to, swing her around like they were little kids again—except she wasn’t a kid anymore. Neither of them were.

He'd bunked off school early today to get some time alone with Mum. They'd spent a lot of 'quality time' together lately—ever since that first slippery afternoon during his incapacity—when her fingers had wandered lower during a bed bath. Katy had been surprised to find that Stan was a very big boy indeed.

Stan almost jumped down the the stairs from the wheelhouse, already hard beneath his school trousers at the thought of what awaited him. The afternoon sun glittered off the narrowboat's polished windows. His Mun was lounging on the sofa, her blonde hair loose around her shoulders, that obscenely short silk robe barely covering her thighs. She liked to tease him—would pretend to be absorbed in her book until he was practically climbing out of his skin—but today her eyes locked onto him the moment his shadow fell across her.

"Hello darling, you're home early," Katy purred, snapping her book shut with deliberate slowness. The silk robe slipped another inch as she stretched, revealing the smooth curve of her hip.
"Missed you," he muttered, kicking off his shoes with unnecessary force. His cock strained against his trousers, the fabric damp with pre-cum.

Stan crossed over to the sofa— he didn’t even bother with the zipper—just shoved the waistband down in one rough motion. His cock sprang free, thick and flushed, the tip glistening. Katy inhaled sharply as it bobbed inches from her lips, the heat radiating off it. She didn’t pull away—just tilted her head up to look at her only just fifteen year old son with amusement, her fingers already sliding between her thighs.

"Is this for me? Katy teased, sliding her hand up to cup his balls while her other hand gave his bum a playful squeeze. "No wonder you couldn't concentrate in class today."

Stan groaned, shifting his weight as her fingers traced slow circles along his perineum, just hard enough to make his hips jerk forward. He wasn't supposed to thrust—she'd made that rule very clear last time—but Katy's lips hovered an inch away, her breath warm and uneven against his leaking tip. She exhaled deliberately, watching the way his whole body trembled when her breath ghosted over his frenulum.

"Patience," she murmured, dragging her tongue along her own bottom lip while her free hand pinched one of her nipples through the silk. The robe gaped open now, revealing the flush creeping down her chest. Stan's fingers tangled in her hair—not pulling yet, just clinging—as she finally, *finally* closed the distance. She slowly lapped up his shaft, savoring the salt of him with kittenish little flicks of her tongue, deliberately avoiding where he needed it most. Her lips brushed the underside of his cock once—twice—hovering just below the swollen head.

"Muuum," Stan groaned, his hips twitching forward involuntarily—only for Katy to tut and press a restraining palm against his pelvis. She kept him there, trapped in that torturous inch of space where her breath ghosted over his weeping slit but her lips refused to close around him. A bead of pre-cum trembled at his tip; Katy watched it gather before taking the head between her lips with agonizing slowness, sucking just hard enough to make his knees buckle.

Her hands slid up his thighs, fingertips skimming the sensitive skin until she found the taut curve of his buttocks—gripping hard, pulling him forward as she took his entire length into her mouth in one slow, deliberate motion. Stan gasped, the sound strangled and raw, as his cock hit the back of her throat. Katy paused there, swallowing deliberately around the swollen head, relishing the way his hips jerked instinctively against her restraining hands.

She paused briefly as the tip hit the entrance to her throat and swallowed, relaxing then eased the rest in smoothly—taking him all the way down until her nose pressed into the wiry blond curls at the base. Stan made a sound like a wounded animal, his fingers tightening in her hair as his hips gave an involuntary twitch. Katy stayed there for a long second, her throat fluttering around him, before pulling back just enough to breathe—then plunged back down in one slick motion.

The wet heat of her mouth was unbearable—the way her tongue curled under his shaft on each outward stroke, the obscene *glrk* as she swallowed around him. Stan could feel every ridge of her palate, every tight squeeze of her throat muscles as she took him deeper, faster. Drool dripped down his balls. He was dimly aware of his own ragged breathing—but mostly he was aware of her, of the way her fingertips dug into his bum whenever he tried to thrust, of the smug little hum she made when he whimpered.

Katy loved this, loved the raw power she had over him—how he trembled under her control, how his breath hitched when she did nothing more than exhale against his skin. But she wasn’t done yet. She gripped his bum hard and literally fucked her own mouth with his cock—bobbing her head with a rhythm that made his thighs shake—until his moans turned desperate, his fingers twisting in her hair like he was clinging to the edge of a cliff.

Drool dripped onto her exposed tits as Katy's lips stretched obscenely around her son's substantial cock, her throat fluttering with each practiced swallow. Stan's breath came in ragged gasps, his fingers tightening in her hair—not guiding, just clinging—as she hollowed her cheeks and sucked harder. The wet uck, uck, uck of her throat taking her son's cock filling the boat's cabin.

"Gonna—" Stan choked out, but Katy just hummed around him, the vibration wringing a broken moan from his chest. She pulled off with a filthy pop, his cock glistening with her spit, and she pinched the base of his cock hard—watching his face contort as he fought not to spill.

"Not yet, darling," Katy murmured, her voice throaty from use, lips swollen and glistening. She released his cock with a slow drag of her tongue along the underside, savoring the twitch of his muscles beneath her fingertips. Her robe had slipped entirely off one shoulder, revealing the flushed swell of her breast where it pressed against his thigh. "I need to feel you inside me."

With deliberate slowness, she untied the silk belt at her waist. The robe pooled around her hips as she rose, letting the fabric slither down her body. Her breasts swung heavy and full, as she turned to kneel on the sofa—placing her hands on the back rest and presenting herself to Stan in a way that left nothing to the imagination. The swell of her bum arched higher as she glanced back over her shoulder, her lips swollen from sucking him. "Come on," she murmured, her voice low and husky. "Fuck Mummy with that big boy cock of yours."

May wandered along the towpath with her backpack slung over one shoulder, kicking at loose pebbles with scuffed school shoes. The afternoon sun made her blonde hair stick to her neck, her too-tight school blouse clinging to skin that hadn't stopped tingling since biology class. Miss Harris had been droning on about mitosis while May squirmed in her seat, pulse throbbing between her thighs every time the wooden chair pressed just there. Thirteen was bad enough—but fourteen? Fourteen was a curse. She was just constantly wet now—like her body had forgotten how to turn off.

She'd skipped her last class—again—hoping to Mum would be out shopping or something. Hoping to get the boat to herself. The thought of pressing her fingers into that throbbing ache between her legs made her walk a little faster, her thighs rubbing together in a way that sent sparks up her spine. May knew she looked like a little kid—flat chest barely stretching her training bra, boyish hips —but inside? Inside she was a furnace. A stupid, stupid furnace that wouldn't *stop*.

The boats curtain were drawn which was weird at this time of day. Usually Mum had them open—liked to watch the ducks and whatever while she drank her afternoon wine. May slowed her steps, her curiosity peaked—maybe mum was doing something she didn't want the neighbors seeing?

May quietly unlocked the door to the wheelhouse and slippped inside. The noise of flesh smacking against flesh hit her ears instantly—wet, rhythmic, unmistakable. Her stomach flipped. She knew that sound. She'd heard that sound many time alone in her bunk at night, fingers jammed between her legs while listening to the noises coming from Mum and Dad's room.

She peered down through the crack between the doors leading to the main cabin—expecting to see her Dad’s broad back, pumping between Mum’s thighs.

What she saw instead made her lungs lock.

Stan—her *brother*—was naked from the waist down, his muscular bum flexing as he gripped Mum's hips. His cock, thick and glistening, disappeared between Mum's spread thighs with each rough thrust. May's fingers dug into the doorframe. Her Mum was naked, knelt on the sofa, arching back into Stan with a low moan—her breasts swaying, her lips parted in pleasure.

May's mouth went dry. She should leave. She should *definitely* leave. But her feet stayed rooted, her pulse hammering between her legs. This was the first time she'd ever *properly* seen a cock—all those internet videos didn't count—and fuck, Stan's was huge.

The glistening shaft hammering in and out of their mum looked like something off a porn movie—not a fifteen-year-old. Thick veins stood proud along its length, the flushed head disappearing into Katy's slick folds with each brutal thrust. May could hear how wet her Mum was—that obscene squelch filling the cabin—and fuck, the sound alone made her clench around nothing. Stan's balls slapped against their mum's thighs with every snap of his hips.

May didn't realize her fingers had slipped under her school skirt until the first jolt of pleasure shot up her spine. The rough seam of her cotton panties ground against her clit as she pressed down—harder than she meant to—and suddenly she was biting her lip. Her hips rocked forward without permission, chasing the friction. She was actually playing with herself while watching her own brother fuck their mum. The realization should have horrified her. Instead, her fingers dug deeper, the damp fabric clinging to her swollen folds—two fingers circling where she burned hottest.

Below, Katy's moans climbed higher. One hand clawed at the sofa cushions while the other slapped frantically at her clit, fingers smearing her own slickness in rough circles. "Oh god—Stanley—right there—" she gasped, her voice breaking as Stan's hips pistoned faster. His cock glistened with her juices, the thick length disappearing into her over and over, the swollen head dragging against her g-spot with every brutal thrust. Katy's thighs trembled—her whole body tensing—as her fingers worked her clit in frantic, sloppy circles.

Katy literally growled as her orgasm took her—back arching, toes curling against the sofa cushions—her cunt clamping down on Stan's cock in pulsing waves. "Fuck, fuck—yes—" she gasped, her fingers digging into his thighs hard enough to leave crescent marks. Stan didn't slow down. If anything, he fucked her harder through it, his balls slapping against her slick skin with wet smacks that echoed through the narrowboat.

May's fingers moved faster under her skirt, the damp cotton of her panties now soaked through. She was panting openly—almost not caring if they heard—her clit throbbing under her frantic touches. The sight of Stan's thick cock glistening with their mum's juices, the way his bum muscles flexed with each thrust—fuck, it was too much. Her thighs trembled, her knees threatening to buckle as heat coiled tighter and tighter in her belly. When it hit—it was maybe the biggest orgasm she'd ever felt. Her vision blurred, her teeth sinking into her own wrist to muffle the gasp that escaped anyway.

Katy's head dropped low, her forehead pressed against the sofa's backrest as another shuddering wave of pleasure wracked her body. But through the haze, through the delicious clench of her cunt around Stan's cock—she noticed something. The angle was just right. A sliver of light from the cracked-open doorway caught her eye—and there, barely visible but unmistakable, was May. Her daughter’s knees were shaking, her school skirt hiked up around her waist, fingers working furiously between her legs as she watched them fuck.

Their eyes locked.

Katy's breath hitched mid-moan—not from the relentless pounding of her son's cock, but from the electric realization that her daughter was *right there*, trembling in the doorway with her panties soaked through. Their gazes held for one endless second: May's wide with panic and arousal, Katy's dark and readable, but she didn't stop Stan—didn't even slow him down. Instead, she arched her back higher, spreading her thighs wider, letting May see everything—the obscene stretch of her lips around Stan's cock, the glisten of their mixed fluids dripping down her inner thighs.

"Fuck—Mum—" Stan groaned, his rhythm faltering as his balls drew up tight. His fingers dug into Katy's hips hard enough to bruise, his cock pulsing inside her as the first hot spurt flooded her cunt. Katy gasped, deliberately loud—for May's benefit—her walls fluttering around him as she milked every last drop.

She could feel his entire weight pressing her down—cheek mashed against the sofa’s upholstery, Stan’s fingers tangled in her hair—as he buried himself to the hilt with a growl. Katy’s breath came in ragged bursts against the fabric, her lips parted around a moan she couldn’t stifle. The angle was brutal, his cock stretching her so wide she swore she could feel the imprint of his pulse inside her. When she twisted her head to glance back at the doorway—praying for another glimpse of May’s wide, guilty eyes—the space was empty. Just a sliver of daylight where her daughter had stood.
