Antwerp, Belgium – Summer 1965
The old house on Korte Zavelstraat stood narrow and tall, like most homes in the old district near the port. Red brick, white lace curtains, and the constant smell of the Scheldt River in the air. It was a Catholic house. A strict house. A house full of secrets.
Hendrik De Vries, 42 years old, had been a widower for four years. He worked as a senior supervisor at the docks, a strong, serious man with thick dark hair and broad shoulders. People respected him. Feared him a little. But inside his own home, something darker had begun to stir.
His daughter Isabelle had turned 19 two months ago. She was the most beautiful girl in the neighborhood — soft pale skin, long chestnut hair, full heavy breasts, and wide curving hips that made her simple dresses look sinful. Since finishing school, she spent most of her days helping with the house.
His son Thomas, 21, worked with him at the port. Tall and quiet, he had always been protective of his little sister.
It was a hot July evening. The windows were open, but the air was still thick.
Isabelle came down the wooden stairs after her bath, wearing only a thin white cotton nightdress. It was old and worn, almost see-through in the right light. Her nipples, dark and stiff from the evening chill, pressed clearly against the fabric. The hem barely reached mid-thigh.
Hendrik was sitting in his armchair reading the newspaper when she walked into the living room. He looked up.
For a long moment, he couldn’t look away.
“Papa, it’s so hot tonight,” Isabelle complained softly, fanning herself. “I can’t sleep.”
Hendrik’s eyes moved slowly over her body — the swell of her breasts, the dark shadow between her legs visible through the thin material. He felt his cock twitch in his trousers.
“Go put on a robe, Isabelle,” he said, his voice low and rough.
“But Papa… it’s only us,” she replied innocently, tilting her head. “Thomas is still out with his friends.”
She walked to the window and leaned forward slightly, looking at the street. The nightdress rode up, revealing the bottom curve of her round, bare ass.
Hendrik gripped the newspaper tighter. His mouth went dry.
That night, after everyone had gone to bed, Hendrik lay awake. His cock was painfully hard. He kept seeing his daughter’s young body in that thin nightdress. The way her heavy tits moved when she walked. The dark triangle between her legs.
He felt deep guilt. She was his own daughter. His flesh and blood. But the more he tried to push the thoughts away, the stronger they became.
The Next Morning
Isabelle was in the small backyard hanging laundry. She was wearing a light summer dress, but the top buttons were open because of the heat. Her cleavage glistened with sweat.
Thomas came home from the night shift and stopped at the back door, watching her. He had noticed how his sister had grown recently. Her body had become that of a woman — full and ripe.
Isabelle reached up to hang a sheet, and her dress rode high on her thighs. Thomas could see the soft curve where her ass met her legs. He felt his cock swell.
“Need help, little sister?” he asked, stepping outside.
Isabelle smiled brightly. “Yes please, Thomas.”
As he helped her, his arm brushed against her breast. Neither of them said anything. But both felt the electricity.
Later that afternoon, while Hendrik was still at work, Isabelle decided to take a bath. The house had only one bathroom, and the lock had been broken for months.
She filled the tub and slipped out of her dress, completely naked. Her body was stunning — large round breasts with pink nipples, a narrow waist, wide hips, and a thick dark bush between her legs.
She didn’t know Thomas had come home early.
He pushed the bathroom door open slightly, thinking it was empty.
There she was.
His own sister, completely nude, stepping into the tub. Water ran down her breasts and over her soft belly. Her ass looked full and perfect as she lowered herself into the water.
Thomas stood frozen, his cock rock hard in his pants. He watched as Isabelle soaped her breasts, lifting them, letting them bounce gently. She ran her hands between her legs, washing her pussy slowly.
He quietly pulled out his cock and started stroking while watching his nude sister.
Isabelle suddenly looked toward the door.
For a split second, their eyes met.
Thomas quickly stepped back, heart pounding. He ran to his room, terrified and more aroused than he had ever been in his life.
That Evening
Hendrik came home tired from the docks. Isabelle had cooked dinner — stoofvlees with fries. She was wearing the same thin white nightdress again.
During dinner, Hendrik kept stealing glances at her chest. Thomas was unusually quiet, still thinking about what he had seen in the bathroom.
After dinner, Isabelle said goodnight and went upstairs.
Hendrik poured himself a glass of jenever and sat in the living room. Thomas joined him.
The two men drank in silence for a while.
Finally, Thomas spoke, his voice low.
“Papa… Isabelle is becoming a woman.”
Hendrik stared into his glass.
“I know,” he replied quietly.
Both men fell silent again, the heavy weight of forbidden desire hanging between them.
Upstairs, Isabelle lay in bed, her hand slowly moving between her legs. She was thinking about the way both her father and brother had been looking at her lately.
She smiled softly in the darkness as her fingers found her wet slit.
The days that followed became heavy with unspoken desire inside the narrow house on Korte Zavelstraat.
Isabelle had noticed how both her father and brother looked at her now. Their eyes lingered longer. They found excuses to be near her. And strangely, she enjoyed it. A secret thrill ran through her young body every time she caught them staring at her breasts or legs.
Two days later, on a Saturday afternoon, the heat was unbearable. Hendrik was working in the small garden behind the house, shirtless, his muscular back shining with sweat.
Isabelle came out wearing a light yellow sundress with thin straps. She had deliberately not worn a bra. Her full breasts moved freely under the thin fabric, her nipples clearly visible.
“Papa, would you like some cold water?” she asked sweetly, standing close to him.
Hendrik looked up. His eyes immediately dropped to her chest. The outline of her stiff nipples was impossible to ignore. He felt his cock thicken inside his work trousers.
“Yes… thank you,” he muttered.
When Isabelle bent over to pour the water, the front of her dress fell forward. For several long seconds, Hendrik had a clear view of both her bare breasts — heavy, round, and perfect. Her pink nipples were hard.
He swallowed hard. His daughter’s breasts were even more beautiful than he had imagined.
That same evening, Thomas came home early. The house was quiet. Hendrik was taking a bath upstairs.
Thomas went to the kitchen for a beer and stopped dead in the doorway.
Isabelle was washing dishes at the sink, her back to him. She was wearing only a short white slip that barely covered her ass. As she reached for a plate, the slip rode up completely, revealing her round, naked bottom and the dark cleft between her cheeks.
Thomas’s cock instantly became rock hard.
He stood there watching his nude sister’s ass for almost a minute before she turned around.
“Oh! Thomas… I didn’t hear you come in,” Isabelle said, pretending to be shy. But she made no attempt to pull down her slip.
Thomas’s eyes were glued to her breasts. The thin material clung to them, showing every curve.
“You… you shouldn’t walk around like this,” he said hoarsely, but his eyes betrayed his words.
Isabelle smiled softly. “It’s so hot, brother. And we’re family. What’s wrong with being comfortable?”
She walked past him slowly, her body brushing against his. Thomas could smell the soap on her skin.
Later that night, after Hendrik had gone to bed, Isabelle went to the bathroom. She left the door slightly open — on purpose.
Thomas, unable to sleep, walked past and saw the light. He quietly pushed the door open a little more.
There was his sister again — completely naked.
Isabelle stood in front of the old mirror, brushing her long hair. Her large breasts swayed gently with each stroke. Her dark pubic hair looked thick and inviting between her soft thighs. She turned slightly, giving him a perfect side view of her curvy body.
Thomas pulled out his throbbing cock and stroked it slowly while watching his nude sister. He was breathing heavily.
Suddenly Isabelle turned her head and looked straight at the door.
This time she didn’t pretend she didn’t see him.
Their eyes locked.
Isabelle’s gaze dropped to his hand wrapped around his hard cock. Instead of screaming or covering herself, she gave a small, shy smile and continued brushing her hair, letting him watch.
Thomas came hard in the hallway, shooting thick ropes of cum onto the wooden floor while staring at his sister’s naked body.
The Following Sunday
After church, the family returned home. The tension in the house was now almost unbearable.
Hendrik drank more jenever than usual. He sat in his armchair while Isabelle sat on the sofa across from him, legs slightly parted. She wasn’t wearing panties. From where Hendrik sat, he could see the dark patch of her pussy hair.
His cock was painfully hard the entire evening.
Later, when Thomas had gone to bed, Hendrik finally spoke.
“Isabelle… come here.”
His daughter stood up obediently and walked over to him. Hendrik’s hands were shaking as he reached out and touched her thigh, just below the hem of her nightdress.
“You’ve grown into a woman,” he said, his voice thick with lust and guilt. “A very beautiful woman.”
Isabelle stood still as her father’s rough hand slowly moved higher under her nightdress. When his fingers touched her bare pussy, she let out a soft gasp.
“Papa…” she whispered.
“You’re wet,” Hendrik groaned, shocked and aroused.
Isabelle bit her lip. “I’ve been wet for days, Papa… because of you and Thomas.”
Hendrik’s fingers gently rubbed her swollen clit. Isabelle moaned softly and held onto his shoulders.
At that exact moment, Thomas appeared at the top of the stairs. He had come down for water and froze when he saw the scene — his father’s hand under his sister’s nightdress, Isabelle’s eyes half-closed in pleasure.
Instead of getting angry, Thomas felt his cock harden again.
Hendrik noticed his son watching but didn’t remove his hand.
“Come down, Thomas,” he said quietly, his voice heavy. “Your sister needs us.”
Isabelle looked up at her brother with lust-filled eyes and whispered:
“Yes… please.”
Thomas slowly came down the stairs, his eyes fixed on the shocking scene before him. His father’s hand was under Isabelle’s nightdress, fingers gently rubbing her most private place. Isabelle stood with her legs slightly apart, breathing heavily, her full breasts rising and falling.
For a long moment, no one spoke.
Then Hendrik, his voice deep and trembling with lust, said:
“Close the curtains, Thomas.”
Thomas obeyed without question. He pulled the heavy lace curtains shut, blocking out the streetlights of Korte Zavelstraat. The living room became dimly lit by only one small lamp.
Hendrik pulled Isabelle’s nightdress up and over her head in one motion. She stood completely naked between her father and brother — her heavy breasts exposed, pink nipples hard, thick dark bush glistening with wetness.
“She’s been teasing us for weeks,” Hendrik said, almost like a confession. “Look at her body… God forgive us.”
Isabelle’s cheeks were flushed, but her eyes were shining with excitement. She looked at her father, then at her brother.
“I want this,” she whispered. “I want both of you.”
Hendrik stood up and kissed his daughter hard on the mouth. Isabelle moaned into the kiss as her father’s rough hands squeezed her breasts. Thomas stepped closer and ran his hands over her round ass from behind.
They led her to the old sofa. Hendrik sat down and pulled Isabelle onto his lap, facing him. He took one of her nipples into his mouth, sucking hungrily while Thomas knelt behind her, kissing her neck and back.
Isabelle was shaking with pleasure.
“Papa… Thomas…” she moaned.
Hendrik freed his thick, heavy cock from his trousers. It was rock hard, veins bulging. Isabelle looked down at her father’s cock with wide eyes.
“It’s so big…” she whispered.
Hendrik guided her hips down. The head of his cock pressed against her wet virgin entrance. Slowly, he pulled her down, inch by inch, stretching her tight pussy.
“Ahhhhh!” Isabelle cried out as her father’s cock entered her completely. She was no longer a virgin.
Hendrik groaned loudly. “My own daughter… so tight… so wet…”
He began thrusting up into her, holding her hips. Isabelle’s big breasts bounced wildly as she rode her father’s cock.
Thomas stood beside them, stroking his own hard cock while watching his sister get fucked by their father. Isabelle reached out, grabbed her brother’s cock, and pulled it into her mouth.
The room filled with wet, obscene sounds — flesh slapping against flesh, moans, and heavy breathing.
Hendrik fucked his daughter harder, his hands gripping her ass.
“You’re mine now, Isabelle,” he growled. “My beautiful incest daughter.”
Isabelle moaned loudly around her brother’s cock.
After several minutes, Hendrik lifted her off and laid her on the sofa. Thomas immediately took his place between her legs.
He pushed his cock into his sister’s freshly fucked pussy in one smooth thrust.
“Oh God, Thomas!” Isabelle screamed in pleasure.
Thomas fucked her with deep, passionate strokes while Hendrik fed his cock into her mouth. Father and son took turns using her young body.
They changed positions again. Hendrik put Isabelle on all fours and entered her from behind, fucking her like an animal. Thomas knelt in front of her, fucking her mouth.
The forbidden pleasure was overwhelming.
“I’m going to cum inside you,” Hendrik suddenly groaned.
Isabelle moaned in response. Hendrik thrust deep and exploded, flooding his own daughter’s womb with thick, hot cum.
As soon as he pulled out, Thomas took his place and slammed into her cum-filled pussy.
“I’m cumming too!” Thomas cried.
He emptied himself deep inside his sister, mixing his seed with their father’s.
Isabelle came violently, her whole body shaking as she experienced the most powerful orgasm of her life.
Aftermath
The three of them lay together on the floor, naked and exhausted. Isabelle rested her head on her father’s chest while Thomas gently stroked her thigh.
Guilt slowly crept in.
“What have we done…” Hendrik whispered, staring at the ceiling.
Isabelle kissed his chest softly.
“We did what our bodies wanted, Papa. I love you both… more than before.”
From that night on, everything changed in the house on Korte Zavelstraat.
During the hot summer of 1965, the De Vries family gave in completely to their forbidden desires. Almost every night, after the curtains were closed, Isabelle was shared between her father and brother. Sometimes they took her together. Sometimes one would watch while the other fucked her.
Isabelle became the center of their world — the nude sister, the incest daughter, and the willing lover who satisfied their darkest urges.
Hendrik and Thomas never fought over her. Instead, they shared her with a strange, twisted bond.
On quiet Sunday evenings, after church, they would return home, lock the doors, and spend hours in sinful pleasure.
The narrow brick house kept their secret well.
And in the conservative Catholic city of Antwerp in the 1960s, no one ever suspected that behind those white lace curtains, a father and son were regularly fucking their beautiful daughter and sister.
The End.
