The alarm clock on Ethan's nightstand blinked 8:17 AM, December 22, 2025. Snowflakes danced lazily outside the frost-laced window of the old suburban house, blanketing the neighborhood in a pristine white hush. Ethan stirred under the thick comforter, his body heavy with the remnants of sleep. At 24, he was back home after grad school, crashing in his childhood bedroom while figuring out his next move. The room still held echoes of his teenage years—posters of classic cars on the walls, a worn baseball glove on the shelf—but now it felt smaller, cozier, especially with the family all under one roof again for the holidays.
A strange sensation pulled him fully awake. Warmth enveloped the lower half of his body, a slick, rhythmic pressure that sent tingles radiating up his spine. His eyes fluttered open, and he lifted the comforter just enough to peek. There, between his legs, was his 19-year-old sister, Lily. Her dark hair cascaded over her shoulders, tickling his thighs as her head bobbed slowly, deliberately. She was on her knees at the edge of the bed, her lips wrapped tightly around his morning erection, sucking with a gentle, teasing insistence. The warmth of her mouth was intoxicating—wet, velvety, and insistent, her tongue swirling lazy circles around the head before sliding down the shaft, taking him deeper with each pass.
Ethan's breath hitched. "Lily... what the—?" He groaned softly, his voice thick with sleep and sudden arousal. She looked up at him through her lashes, her blue eyes sparkling with mischief, but she didn't stop. Instead, she hummed around him, the vibration sending a jolt straight to his core. She pulled back just enough to speak, her lips glistening with saliva and a hint of pre-cum.
"Morning, big bro," she murmured, her voice husky and playful. "Welcome home properly. Figured you'd need a wake-up call after that long drive yesterday." She dove back down, her hand wrapping around the base of his cock to stroke in tandem with her mouth. Ethan was fully hard now, his length throbbing against her tongue. He could feel every detail—the way her cheeks hollowed as she sucked, the slight graze of her teeth on the underside, the way she twisted her wrist just right to heighten the friction.
His hips bucked involuntarily, pushing deeper into her warmth. The taboo thrill of it all—the fact that this was his little sister, home from her first semester at college, greeting him like this—only amplified the heat building in his groin. They'd established the family rules years ago, after their parents' divorce left just Mom, Ethan, and Lily in the house. It started as a way to stay close, to blur the lines in a world that felt too cold otherwise. Free use: anytime, anywhere in the shared spaces, as long as everyone was game. And they all were, enthusiastically. But this morning surprise? It was Lily's way of saying she'd missed him.
Just as Ethan's mind started to fog with pleasure, the door creaked open. Their mom, Elena, poked her head in. At 44, she was a vision of effortless sensuality—curvy in all the right places from years of yoga, her auburn hair tied back in a loose ponytail, wearing a simple robe that hugged her ample breasts and hips. She took in the scene without a flicker of surprise: Lily on her knees, Ethan's cock disappearing into her mouth, his face contorted in bliss.
"Breakfast is ready, you two," Elena said casually, as if she'd walked in on them brushing their teeth. "Pancakes, bacon, fresh coffee. Don't let it get cold." She smiled warmly, her eyes lingering for a moment on the way Lily's head moved, before turning to leave.
Ethan was close now, the pressure building like a coiled spring. His balls tightened, and he gripped the sheets, thrusting shallowly into Lily's mouth. She sensed it, popping off with a wet smack, a string of saliva connecting her lips to his tip. "Guess that's my cue," she said with a grin, wiping her mouth with the back of her hand as she stood up. She was wearing nothing but an oversized T-shirt—his old one, actually—that skimmed her thighs, her perky B-cup breasts pressing against the fabric, nipples hard from the cool air or arousal or both.
But Ethan wasn't done. Horny beyond reason, he lunged forward, grabbing her wrist. "Oh no you don't," he growled, his voice low and commanding. With a swift pull, he yanked her back toward the bed. Lily yelped in surprise, stumbling onto the mattress on her hands and knees. Ethan was behind her in an instant, flipping up the hem of her T-shirt to expose her bare ass and the slick folds of her pussy. She wasn't wearing panties—typical in their house.
"Ethan, wait—Mom said breakfast!" Lily protested half-heartedly, but her body betrayed her, arching back toward him as he positioned himself.
"Breakfast can wait a minute," he muttered, his hands gripping her hips. He rubbed the head of his cock against her entrance, feeling her wetness coat him immediately. She was soaked, probably from sucking him off. With one firm thrust, he buried himself inside her, inch by inch. Lily gasped, her walls clenching around him like a vice—tight, hot, and welcoming. He didn't rush; he savored it, pulling back slowly to feel every ridge and flutter before slamming back in, bottoming out with a slap of skin on skin.
"Oh fuck, yes," Lily moaned, pushing back to meet him. Ethan set a steady rhythm, his hips pistoning as he fucked her from behind. Each thrust was deliberate: out almost to the tip, teasing her entrance, then deep and hard, his balls swinging against her clit. He reached around, his fingers finding her swollen nub, circling it in time with his movements. Lily's breath came in short pants, her fingers digging into the comforter. "Harder, bro... just like that..."
The door opened again, and Elena stepped fully inside this time, arms crossed but with an amused smirk. I said, "be quick, Ethan. The pancakes are getting cold." She leaned against the doorframe, watching without interruption. If anything, her presence spurred him on—the free-use rule extended to voyeurism, and Mom loved to watch her kids enjoy each other.
Ethan grunted, his pace quickening. Sweat beaded on his forehead as he pounded into Lily, the bed creaking under them. He felt her tighten, her orgasm building. "I'm close... gonna cum inside you," he warned through gritted teeth.
"Do it," Lily whimpered, her voice breaking. "Fill me up, Ethan..."
With a final, deep thrust, he exploded, ropes of hot cum spilling into her depths. He held her hips flush against him, grinding as he emptied himself, feeling her pulse around him in her own release. Lily cried out, collapsing forward onto the pillows, her body shuddering.
Elena clapped lightly. "Alright, lovers. Clean up and come eat. We've got a whole day ahead." She turned and left, her robe swishing behind her.
Ethan pulled out slowly, watching his cum drip from Lily's pussy onto the sheets. He gave her ass a playful smack. "Good morning to you too, sis."
They dressed quickly—Ethan in sweats and a hoodie, Lily throwing on shorts under the T-shirt—and headed downstairs. The dining room smelled like heaven: maple syrup, crispy bacon, fresh-brewed coffee. Snow continued to fall outside the bay window, turning the world into a winter wonderland. Elena had set the table perfectly, with holiday placemats and a small poinsettia centerpiece.
They ate normally, as if nothing had happened. "So, Lily, how's college treating you?" Elena asked, passing the syrup.
"It's intense, but fun," Lily replied, munching on a pancake. "Dorm life is wild, but nothing like home." She shot Ethan a sly glance, and he chuckled, sipping his coffee.
Ethan chimed in about job hunting, Elena shared a funny story from her yoga class. It was mundane, comfortable—the kind of family breakfast that hid their secret dynamic beneath the surface. No one mentioned the morning romp; it was just part of the routine.
After breakfast, Lily stood and stretched. "I'm gonna hop in the shower. Feel grimy from the drive yesterday." She disappeared upstairs, leaving Ethan and Elena to clear the table.
Elena stacked the plates, her robe parting slightly to reveal the curve of her breast. At 44, she was stunning—full D-cup breasts, a soft belly from life, wide hips that swayed as she walked to the kitchen sink. Ethan followed with the glasses, offering, "Let me help, Mom."
She set the plates down and turned, a thoughtful look crossing her face. "No need for the dishes, sweetie. But..." She glanced around the empty kitchen, then bent over the counter, her robe hiking up to expose her bare ass and the trimmed patch of hair above her pussy. She wasn't wearing anything underneath either. "You could help me this way. I've been thinking about you all morning."
Ethan's cock twitched back to life instantly. The sight of his mom presenting herself like that—casual, inviting—never failed to ignite him. He stepped behind her, his hands sliding up her thighs. "Anything for you, Mom," he said, his voice dropping an octave.
He dropped his sweats, his semi-hard length springing free. Elena reached back, guiding him to her entrance. She was already wet, her arousal evident from watching them earlier. Ethan pushed in slowly, savoring the way her mature pussy enveloped him—looser than Lily's but incredibly warm and responsive, her inner walls gripping him with practiced ease.
"Mmm, that's my boy," Elena sighed, bracing against the sink. He started thrusting, slow at first: out to the tip, feeling the cool air on his slick shaft, then back in, deep and deliberate. Each movement made her breasts sway under the robe, and she pushed back to meet him, their bodies syncing perfectly.
Ethan's hands roamed up her sides, under the robe to cup her heavy breasts, pinching her nipples until they hardened like pebbles. "You feel so good, Mom," he groaned, picking up speed. The slap of his hips against her ass echoed in the kitchen, mingling with the drip of the faucet she'd turned on to mask the noise, just in case.
Elena moaned softly, her head dropping forward. "Harder, Ethan. Fuck your mom like you mean it." He obliged, pounding into her now, each thrust forcing a gasp from her lips. He reached down, his fingers finding her clit, rubbing in firm circles. She was dripping, her juices coating his balls as they slapped against her.
"Don't stop... right there..." Elena's voice trembled. Her orgasm hit first—her pussy clenching rhythmically around him, milking him as she bit her lip to stifle a cry. Ethan followed seconds later, burying himself deep and unleashing another load, his cum mixing with her wetness as he ground against her.
They stayed like that for a moment, catching their breath. Elena straightened, turning to kiss him softly on the lips. "Thanks for the help, sweetie. Now go relax."
Ethan pulled up his sweats, still buzzing from the release, and wandered upstairs. He needed to piss and maybe brush his teeth. Pushing open the bathroom door without thinking—old habit—he froze. Lily was in the shower, steam billowing from behind the glass door. Her silhouette was visible: petite frame, water cascading over her perky tits and down her flat stomach.
"Oh shit, sorry, Lil—I forgot you were in here," he said, starting to back out.
But Lily's hand shot out, grabbing his arm and yanking him inside. She slammed the door shut behind him, her wet body pressing against his clothed one. "Nuh-uh. Now it's my turn to be on top. Payback for this morning, bro." Her eyes gleamed with determination, water dripping from her hair onto his shirt.
Before he could protest, she shoved him against the sink, tugging down his sweats. His cock, still semi-hard from Mom, sprang free. Lily dropped to her knees on the bathmat, taking him into her mouth again—but this time, it was quick and purposeful, getting him fully erect in seconds. Her tongue worked magic, swirling and sucking until he was throbbing.
Then she stood, pushing him onto the closed toilet lid. The bathroom was warm and humid, the mirror fogged. Lily straddled him, her wet pussy hovering over his lap. "My rules now," she whispered, lowering herself onto him inch by inch. He slid in easily, her tightness from earlier now slick with shower water and renewed arousal.
She started riding him slowly, her hands on his shoulders for leverage. Up and down, grinding her clit against his pubic bone with each descent. Ethan groaned, his hands gripping her ass, helping her bounce. "Fuck, Lily... you're so tight."
"Faster," she demanded, picking up the pace. Her breasts jiggled with each thrust, nipples brushing his chest through his dampening shirt. She leaned forward, kissing him deeply, their tongues tangling as she rode him harder. Every second was etched in sensation: the slap of her ass on his thighs, the way her walls fluttered around him, the steam making their skin slick.
Ethan thrust up to meet her, his hips lifting off the seat. "I'm gonna cum again," he warned.
"Not yet," Lily panted, slowing to a grind, teasing him. She circled her hips, feeling him throb inside her. Then she sped up again, bouncing furiously. Her orgasm built fast—her head thrown back, moans echoing off the tiles. "Now... cum with me!"
They climaxed together, Ethan's seed spilling into her for the second time that morning as her pussy spasmed around him. Lily collapsed against his chest, both of them panting.
"Best shower ever," she murmured.
The day was just beginning, and in their free-use home, there was no telling what else the holidays held.
