Incest Harmony

The Miller house was quiet within the soft glow of the evening lights, the kind of ordinary suburban silence that hid a thousand silent wishes. In her room at the end of the hallway, eighteen-year-old Ana Miller was stretched across her bed, the soft, heavy weight belonging to her body sinking deeply into the mattress. Ana was quite fat — carrying a lot of extra pounds that made her belly soft and round, her hips wide and thick, her thighs massive and plush, and her heavy breasts large and pendulous. Because of her size, no boys had ever shown real interest in her. She had never been kissed, never been touched, and remained a complete virgin at eighteen.

Her long golden-brown hair, with straight bangs framing her round face, fanned out upon the pillow while she scrolled endlessly on her phone. Every evening she locked herself away in her room and devoured erotic stories. She was most intrigued by taboo themes — the forbidden, the wrong, the danger — but she had never once imagined her own brother or any family member in those fantasies. The stories were pure escapism, a place where she could pretend to be the desired heroine, wanted desperately despite her body.

Tonight her hand had already slipped beneath the waistband of her pink cotton panties, lazily circling her swollen clit while she read. Her breathing was soft and shallow, her thick nipples stiff against the thin material of her oversized sleep shirt, when a sudden raised voice broke the quiet.

It came from Jake’s room.

Ana froze, heart beating. Her twenty-three-year-old brother Jake rarely raised his voice. Curiosity hauled her off the bed. She moved as quietly as her heavy body allowed, tiptoeing down the hallway until she reached a bit ajar door. A sliver of warm lamplight spilled out. She pressed herself against the wall, looking through the gap; one hand still tucked inside her soaked panties.

Inside, Jake stayed shirtless, his athletic, toned body tense with frustration—six months with Emma, and still nothing more than heavy petting. Emma, a slim, confident brunette with striking features and a wicked smile, faced him with her hands on her hips.

“If it’s so fucking important to you,” Emma said, tone low and irritated, “then sit on the bed, Jake.”

Jake hesitated only a second before obeying, dropping onto the edge of his bed. His sweatpants were already tented. Emma sank gracefully to her knees between his spread legs, her manicured fingers hooking into the waistband of his boxers and yanking them down in one smooth motion.

Ana’s breath stuck in her throat.

Jake’s cock sprang free — thick, veined, and rock-hard, the swollen head already radiating with a bead of precum. It was bigger than anything Ana had seen in pictures. Emma wrapped her hand around the base, stroking once, twice, then leaned forward and took him into her mouth without hesitation.

“Mmmph…” The wet, obscene sound of Emma’s lips stretching around Jake’s thick girth filled the room. She bobbed her head slowly at first, taking more of him with each downward glide, her tongue circling the sensitive underside. Saliva quickly coated his shaft, dripping down to his heavy balls as she worked him more deeply, her cheeks hollowing with strong suction.

Jake groaned deeply, one hand tangling in Emma’s dark hair. “Fuck, Emma… just like that…”

Ana couldn’t look away. Her own fingers went quicker inside her panties, rubbing tight, frantic circles over her throbbing clit. She watched every filthy detail — the way Emma’s throat bulged slightly when she forced Jake’s cock deeper, the lewd gluck-gluck-gluck sounds of her eager, sloppy sucking, the way Jake’s muscular thighs tensed, and his abs flexed with pleasure. Strings of spit and precum leaked from the corners of Emma’s stretched lips, running down her chin as she sucked harder and faster.

Ana’s virgin pussy clenched hard around nothing. She pushed two fingers inside her soaked hole, biting her plump lower lip to stay quiet while she fucked herself in sync with Emma’s bobbing head. Her massive breasts heaved with every unsteady breath, her soft belly quivering. The sight of her brother’s thick cock disappearing into another girl’s mouth was driving her wild.

Jake’s hips began to buck gently, fucking Emma’s face. “Shit… your mouth feels so fucking good, baby…”

Emma moaned around his cock, the vibration making Jake curse louder. She took him all the way to the back of her throat, held him there, then pulled back with a quick gasp, long strands of saliva still uniting her swollen lips to his glistening, veiny shaft. Then she drove down again, even sloppier, even hungrier.

Ana’s thick thighs trembled. Her digits plunged deeper, curling against her most sensitive spot while her thumb caressed her swollen clit in fast, desperate circles. She was dangerously close to the edge, spying on her own brother like this.

She didn’t know how long she stood there, fingers buried in her dripping pussy, watching the filthy blowjob happening just feet away… but she couldn’t stop.

And deep down, she didn’t want to.

Jake’s grip on Emma’s head tightened, his fingers digging into her dark hair with sudden, almost angry strength. Six long months of frustration boiled over at that moment. Six months of dates, gifts, patience, and endless blue balls while Emma kept him at arm’s length. Now he was done waiting.

He thrust his hips forward, forcing more of his thick cock down her throat. “That’s it… take it all, you fucking tease,” he growled, voice low and rough.

Emma’s eyes widened in surprise, but Jake didn’t care. He held her head firmly in place, fucking her face with deep, demanding strokes. His heavy balls slapped against her chin as saliva poured from her stretched lips, dripping onto her tits and the floor. The wet, choking sounds echoed obscenely through the room.

Ana watched from the hallway, mesmerized. Her fingers moved frantically inside her soaked pussy, plunging in and out while her thumb rubbed her swollen clit in tight, desperate circles. Her massive, soft belly quivered, her huge breasts heaving heavily inside her sleep shirt. She could feel her own orgasm building fast — a powerful, crushing wave that made her thick thighs shake.

Jake’s pace became merciless. He slammed his cock repeatedly into Emma’s throat, using her mouth like a toy. “Fuck… I’m goanna cum,” he groaned, eyes half-closed in raw pleasure.

At that exact moment, Ana’s own climax crashed over her.

A powerful, toe-curling orgasm ripped through her virgin body. Her pussy clenched violently around her thrusting fingers, flooding them with hot, creamy juices that ran down her thick thighs. She slapped one hand over her mouth to muffle the loud, involuntary moan that tried to escape; her golden-brown hair with bangs falling messily over her flushed, round face. Her entire plump body trembled uncontrollably — soft rolls of fat jiggling as wave after wave of intense pleasure tore through her.

At the same time, Jake buried his cock to the hilt in Emma’s throat and exploded.

“Fuuuuck!” he snarled, holding her head locked against his pelvis as thick, powerful ropes of cum shot straight down her throat. Emma immediately started choking, her eyes watering, tears streaming down her cheeks. She gagged hard, her throat convulsing around his pulsing shaft, but Jake didn’t let go. He kept her pinned there, forcing her to take every drop of his pent-up load.

Cum began leaking from the corners of her stretched mouth, mixed with thick saliva, dripping down her chin in messy white strands. Emma’s face turned red, tears flowing freely as she struggled for air, yet Jake held her there a few cruel seconds longer, savoring his revenge.

Ana couldn’t believe what she was seeing. Her brother — usually so calm and kind — looked savage, dominant, almost dangerous. The sight of him ruthlessly face-fucking his girlfriend and flooding her mouth with cum should have shocked her… but instead it only made her orgasm even stronger. A second, smaller wave hit her, making her knees buckle. She had to lean against the wall to stay upright, fingers still buried deep inside her spasming cunt.

Finally, Jake released Emma’s head. She pulled back, gasping and coughing, long strings of cum and spit connecting her swollen lips to his still-hard cock. Tears ran down her flushed face as she struggled to catch her breath.

Ana’s heart hammered wildly. While she still had the strength, she quietly turned away from the door and hurried back to her room as fast as her heavy body would allow. The moment she closed her door behind her; her legs gave out. She collapsed onto her bed face-first, burying her face in the pillow as the full intensity of her orgasm continued to ripple through her.

She had never felt anything like this in her life.
