After Madison Wallace crawled out of bed on a Saturday morning, she noticed neither her son Charlie, nor her daughter Chloe, were up yet. The digital clock on the kitchen stove told her it was after 9. This wasn't alarming; after all, younger people tended to stay up all night and crash at dawn. Still, it concerned Madison enough to investigate.
She peeked in on Charlie first. Her son wasn't much for décor. A jacket hung on the wall next to the door. He'd put up flags with various sports team logos. A guitar case sat in the corner. His twin-sized bed had brown sheets. It had been built a long time ago; a previous generation of Wallaces purchased it and eventually handed it down to this one. That was back when furniture was built to last, so even though it had the craftsmanship reminiscent of the late '70s, there was no need to replace it.
"Hey, sleepy bones," Madison said, to a lump that rose and fell under the comforter. "You know it's after--"
Her foot landed on soft underwear. They weren't discarded boxers or men's briefs, either.
They were panties.
Madison grinned.
"How long was Chloe in here?" she said to herself.
She moved, with slyness, toward the lump. "Judging by how knocked out you are, Charlie, I'd say it was a long time."
She drew the comforter back, revealing a naked bottom half.
"Ungh?" the lump said.
Madison climbed onto the bed until her head was between Charlie's legs. His flaccid cock rested on its side, looking as tired as the young man attached to it.
Charlie made confused grunts as Madison cradled his limp dick. She brought her nose to it and breathed it in deep. A mixed scent wafted into her nostrils, sending desire surging through her body.
"Yeah, your sister kept you busy, alright. I can smell the both of you," Madison said.
She hocked spit in her hand and stroked Charlie's cock up and down with it. "How long has it been since she was in here? Did she slip back into her room as I was getting up, Charlie?"
Madison couldn't resist continuing to smell him as she teased his dick. The aroma of their sin made her uncovered pussy throb under her night shirt. If she kept this up, it would dampen the sheets. She tried to keep her legs from wriggling while Charlie stirred awake and sat up.
"Huh? Wha? Mom?"
It was no longer satisfactory enough for Madison to smell him. She had to taste him as well.
She slipped his ballooning cock into her mouth and bobbed up and down. The distinct flavor of sex was instant, recognizable, and arousing. Madison nursed his dick, savoring the taste of incestuous passion.
Plopping him out of her mouth to stroke him, she asked, "how long was she in here, Charlie?"
"All night," Charlie said, confused, half-asleep.
"Oh, of course she was," Madison said.
Chloe had inherited almost everything from her mother, including her eagerness, persistence, and perfectionism. The comparisons fell short, however, in terms of physical appearance. Madison was taller, slightly thicker, with dark brown hair down to her shoulders. Chloe was shorter and thinner. Her hair was fiery red, and freckles dotted her entire body from head to toe.
Madison stroked Charlie as she moved down to slurp his balls. The odor of pussy was strong there, too. Chloe had left plenty of herself behind for Madison to discover.
"And even after all that," Madison said, rubbing his cock on her cheek, "you still get hard in an instant."
She wolfed his cock as far into her mouth as possible. She moved faster now, with more creativity. The mixture of sibling cunt and cum stirred her appetite to ravenous hunger. The desire grew as she sucked, licked, and kissed Charlie's hard dick.
"Oh, Mom," Charlie moaned. "Oh. Shit! Mom!"
He rose up and down with her sucks. Groaned. Tangled his fingers in her hair. His positive response encouraged her to keep sucking. She could tell, from her many years of cocksucking practice, that he was close to an orgasm--so soon, too, after what his sister put him through!
Madison went dizzy. Sucking off Charlie had awakened her in the right ways, and now she wanted to act in the wrong ones. Like a puppet controlled by an unseen hand, she removed Charlie's cock from her mouth and stood up.
"Mom? Where you going?" Charlie asked.
Where indeed? Smiling--she hadn't stopped smiling since discovering the damning evidence--Madison picked the panties up off the floor.
"This is how I found out what you were up to," Madison said. "That little slut didn't bother picking them back up when her dirty tail skipped out of here."
She crawled between Charlie's legs again. His cock, glistening with his mother's saliva, remained at full attention. She pushed her face into Chloe's panties and breathed them in deep, inhaling sweat and pussy.
Madison, on the edge of coming without touching herself, wrapped the panties around Charlie's cock. She spat in her hand again. She pumped up and down, rubbing the fabric on Charlie's shaft.
"Oh God, Mom, oh Christ," Charlie groaned.
"Yeah? How's that feel, Charlie?" Madison asked.
His cock toughened against the cloth as Madison jerked him off with them. Precum blossomed and spread, creating a new stain.
"I bet your sister's vagina was tight," Madison cooed, enjoying his reactions. "Did you take her from behind? Slap your testicles against her ass before you emptied them inside her? Or did she ride you, Charlie?"
"R-rode..."
Madison squeezed his cock tighter, molding the wadded-up panties into the shape of his hard-on. She could tell, from his heating dick, that he was close.
And she wanted to see. Wanted to watch him spurt and delight in her work.
"Come on Charlie," she moaned, her own climax brewing between her legs. "I know you've got more in there. You always do."
"Oh shit," Charlie said. "M-Mom!"
He let out a growl. Hot white cum filled Chloe's panties. Madison growled too, unable to keep still as an orgasm ripped through her. It satisfied every craving in a roaring blast of pleasure.
When her climax receded, she still clutched the soiled wad against Charlie's waning dick. She waited until he went limp before untangling it from them.
Then she left the bed. She kissed him, not in a sensual way, on the cheek. Charlie was in a daze, still coming down from his climax, his cock oozing spunk.
"Well, rest a little bit more then," said. "But if you don't mind, I'm gonna take this laundry with me."
She left Charlie's room.

In contrast to Charlie's bedroom, Chloe's showed more effort. The wallpaper was of a flower pattern that almost matched her comforter's design. A small TV faced it from the shelf.
Like Charlie's room, though, much of the furniture was made up of hand-me-downs put to practical use. The decorations, also heirlooms, consisted of an ancient, giant teddy bear slumped beside the door. Various animal statuettes sat around the room. They were less of a reflection of Chloe's personality, and mostly placed in her to fill space. The bed, also a twin, had sheets of white.
Chloe had slipped under the warm comforter moments ago. She fell immediately into a deep slumber.
Somewhere in her fogbank of comatose dreams, Charlie still lay beneath her as she rotated her hips. The memory stimulated her pussy.
And somewhere in that incoherent void, a single word emerged: "Chloe."
It caught her attention. She'd recognized that word once. It meant something. It might've been her name, but it also could have described a kind of banana.
"Chloe?"
"Mgh?" Chloe herself might have made that noise, but hippopotamuses that transformed into snakes also made noise.
"...Chloe? Pretending...?"
There was a great disturbance in the sheets. She rolled over, hoping the unwanted element would take a hint and leave her alone.
But it didn't go away. Instead, it whispered the word 'Chloe' again, tingling her ear with warm breath.
"Hrmmm?" Chloe said, returning to the void again.
"Chloe, are these yours?"
Something warm and wet and smelling of bleach landed on Chloe's face. Her eyes shot open as the disturbance hurled her headfirst into the real world.
She jumped up onto her elbows. "Hrmm! Huh! Who!"
"You left these in Charlie's room," Madison said.
The mixed-up jigsaw puzzle formed, if only for a moment, a coherent picture. The unwanted entity who'd disturbed Chloe's rest was her mother. A pair of underwear--panties--caused her rude awakening.
"Oh," Chloe said.
The panties--her panties--were covered in warm semen. She forgot to collect them when she skipped out of her brother's room this morning. She couldn't remember Charlie coming all over them, though. As far as she recalled, they'd been out of the line of fire all night.
She grinned under the cummy mask. "Oops."
She fell back down and shut her eyes.
"Don't 'oops,' me young lady," the voice said, reverting to an unrecognizable specter. "We're not out of this yet. In fact..."
The panties lifted from Chloe's face, leaving dribbles of sperm clinging to her cheeks. The specter inhaled deep, and then made noises suggesting an obvious orgasm.
"Hmm?" Chloe said. Now she really was pretending to be asleep. Half of this was a game, the other genuine. She wanted to tease her mom, but she also wanted to sleep in peace.
The weight on her bed shifted. Her eyes still closed, Chloe understood Madison was crawling atop her prone form. A tongue made a deep brush stroke against her face, scooping up the cum. It tickled, making her giggle.
The sheets drew back. If Chloe were omnipresent, she would have seen a girl wearing an old, worn-out t-shirt a size too big for her. It revealed her freckled skin and the swells of her braless breasts.
The sheets went further down still. "Ugh, Mom, it's
cold
," Chloe whined, the change in temperature teasing her bare ass.
Madison rubbed her exposed glutes. Then she gave her daughter's ass a swift spank.
"Ooh!" Chloe yelped, trying not to grin despite the sting.
Madison positioned Chloe's prone form until it laid flat. She pried her daughter's legs apart. Air blew across Chloe's swollen and distended pussy, still aroused after a night with Charlie's cock in it. Fingers spread her lips apart, exposing, she was sure, the inner pink beneath.
