📖 8 mins read

Luke and Jeannie had been fucking for three years.

They were full-blood siblings—same mother, same father, same dark hair, same sharp blue eyes. Luke was twenty-eight, a former college wrestler who still trained like he was cutting weight. Jeannie was twenty-six, lean and flexible, with the kind of body that made people stare when she walked into a room. They had grown up in the same house in rural New Hampshire, shared the same bathroom, the same dinner table, the same secrets. The first time they crossed the line they were both already adults. Neither of them had ever looked back.

Their aunt Claire was forty-two, six months pregnant, and still the hottest mature woman either of them had ever seen. She lived an hour north of Concord with her husband Mark, a quiet, soft-bodied accountant who had long ago admitted he was a cuckold. Claire’s pregnancy had only sharpened her appetite. She wanted her nephew’s cock. She wanted her niece’s cunt on her face. She wanted Mark to hear every filthy detail afterward and then clean whatever was left of them off her body.

The three of them met at a roadside diner off I-93 after Luke finished a regional wrestling conference. The place smelled of coffee and fried potatoes. Luke was still in the black hoodie that stretched across a wrestler’s shoulders and chest. Jeannie slid into the booth beside him, thigh pressed hard against his. Claire arrived a few minutes later, belly rounded and heavy under a soft cream sweater, cheeks flushed from the cold New England air.

“Found you,” she said, voice low. She sat across from them, one hand resting on the curve of her stomach. “Mark already knows I’m with you both tonight. He asked me to make sure there’s cum for him to eat when I get home.”

Jeannie’s hand slid under the table and cupped Luke’s cock through his jeans. “We’ll make sure there’s plenty.”

They ate quickly. The drive to the cabin in the White Mountains took forty minutes. By the time the door closed behind them the air was already electric.

Claire undressed first. The pregnant belly was full and tight, dark line running from navel to the trimmed patch of hair above her cunt. Her tits were heavy, nipples dark and swollen. She looked at her niece and nephew with open hunger.

“I want to watch my brother’s children fuck first,” she said. “Then I want both of you on me.”

Luke and Jeannie didn’t need more invitation. They stripped fast. Luke’s body was solid muscle—broad shoulders, thick thighs, the heavy cock that Jeannie had been riding for years. Jeannie’s body was tight and strong, small tits, hard nipples, the same blue eyes as her brother staring up at him as she dropped to her knees.

She took him into her mouth in one smooth motion. The blowjob was wet and filthy from the first second—tongue working the underside, throat opening, spit running down her chin. Luke’s hand fisted in her hair. He fucked her face with short, controlled thrusts, the same power he used on the mat. Jeannie moaned around him, eyes watering, taking every inch until her nose pressed against his stomach.

Claire watched from the chair, legs spread, two fingers working her cunt while her free hand cradled her belly. “That’s it, baby. Suck your brother’s cock. Get him nice and hard for your aunt.”

Jeannie pulled off with a wet pop, strings of spit connecting her lips to the head of Luke’s cock. She turned, dropped onto all fours on the bed, and looked back over her shoulder.

“Fuck me, Luke. Hard.”

He mounted her in one thrust—deep, brutal doggie style. The sound of skin on skin filled the cabin. Jeannie’s tits swung under her. Luke’s hands gripped her hips hard enough to bruise. He fucked his sister like he owned her, long strokes that bottomed out every time, the wet slap of his balls against her clit loud in the quiet room. Jeannie came first, body locking up, cunt clenching around her brother’s cock while she cried out his name.

Luke pulled out before he finished. He was saving it.

Claire stood carefully and climbed onto the bed. She settled onto her back, pillows supporting her belly and lower back. “Jeannie. On my face. Now.”

Jeannie straddled her aunt’s head without hesitation. She lowered her soaked cunt onto Claire’s mouth and started grinding. Claire’s tongue pushed into her immediately—long, greedy licks, sucking on her clit, tongue-fucking her niece while Luke knelt between Claire’s spread thighs.

He pushed into his aunt’s pregnant cunt in one slow, deep stroke. Claire moaned into Jeannie’s pussy. Luke fucked her with the same relentless rhythm he had just used on his sister—deep, powerful thrusts that made her heavy belly shift. Jeannie rode Claire’s face harder, grinding down until Claire’s nose was buried and her tongue was buried deeper. The mature woman’s hands gripped Jeannie’s thighs, holding her in place while she ate her niece like she was starving.

Luke reached forward and pinched Claire’s swollen nipples. Claire came hard around his cock, body shaking, tongue never stopping on Jeannie. Jeannie followed seconds later, flooding her aunt’s mouth, thighs trembling as she kept grinding through the orgasm.

Luke pulled out. He stroked his cock twice and painted Claire’s face—thick ropes of cum across her cheeks, her lips, her open mouth, some of it landing on Jeannie’s inner thighs where she still straddled her. Cum facial, heavy and white.

Jeannie leaned down immediately. She licked the cum off her aunt’s face in long, deliberate strokes, gathering it on her tongue, then kissed Claire deep so they could share it. Claire swallowed what she could. Jeannie swallowed the rest. Then Jeannie scooped the last streaks from Claire’s cheeks with two fingers and fed them into her aunt’s mouth so Claire could swallow again.

They barely rested.

Claire rolled carefully onto all fours, pillows arranged under her belly for support. “Both of you. I want my nephew in my cunt and my niece’s cunt on my face again.”

Luke moved behind her and sank back into her in one hard thrust—doggie style, deep and steady. Jeannie crawled in front and sat on Claire’s face the other way this time, facing Luke so she could watch her brother fuck their aunt. Claire’s tongue worked overtime, licking and sucking while Luke’s cock stretched her open. The pregnant woman was soaked, juices running down her thighs with every thrust.

Luke reached around and rubbed Claire’s clit. She came again, moaning into Jeannie’s cunt. Jeannie ground down harder, using her aunt’s face until she came a second time, thighs clamping around Claire’s head.

Luke pulled out, stroked himself, and came across Claire’s lower back and the upper curve of her ass. Jeannie was there instantly—tongue dragging through the thick cum, collecting it, then leaning forward to spit it into Claire’s open mouth so her aunt could swallow. The rest she licked clean herself and swallowed.

They switched again. Claire on her back once more. Luke fed his cock into her mouth while Jeannie sat on her face a third time. The blowjob was messy and eager—Claire took him deep, throat working, spit running down her chin and onto her pregnant belly. Luke fucked her face with short thrusts while Jeannie rode her tongue. When Luke came he held himself deep and pumped every drop down his aunt’s throat. Claire swallowed without spilling a drop, eyes watering, moaning around his cock.

Jeannie came on Claire’s tongue one final time, shaking, then collapsed beside her.

They lay there in the dim light of the cabin, the New England night pressing against the windows. Claire’s face was shiny with spit and leftover cum. Her cunt was swollen and used. Jeannie’s thighs were wet. Luke’s cock was still half-hard, glistening.

Claire touched her belly gently. “Mark is going to lose his fucking mind. I’m going to tell him how his pregnant wife got fucked by her nephew while her niece sat on her face. How I swallowed both of you. How my brother’s children used me like a toy and then made me eat every drop. He’s going to get on his knees the second I walk through the door and clean whatever’s left out of me.”

Jeannie leaned over and kissed her aunt’s mouth, tasting her brother on Claire’s tongue. “Tell him everything. Tell him we made you our cum dump for the night.”

Luke’s hand rested on Claire’s belly, then slid down between her legs, two fingers pushing into her used cunt. “We’ll do it again next month. Same cabin. Same rules. You, me, and my sister. And Mark can keep eating whatever we leave behind.”

Claire smiled, eyes half-lidded, legs still open. “Yes. All of it. Hot as fuck and exactly what I need.”

Outside, the wind moved through the pines. Inside, the three of them stayed tangled together—brother, sister, and pregnant aunt—bodies still warm, still sticky, already thinking about the next time they would do it all over again.
