The night was as dark as ink, the city lights flickering outside the window. In the Lin family's apartment, only faint lighting and the low hum of the air conditioner remained.
Lin Wanqing had just returned from working overtime at the company. She took off her high heels, her long hair cascading over her shoulders. She was twenty-six this year, tall and slender with fair skin. Dressed in a simple white blouse and black skirt, she couldn't hide the curves of a mature woman. The living room was dark; she thought her younger brother Lin Haoran hadn't returned yet.
"Sis..."
A low voice came from the shadows of the sofa. Lin Haoran was sitting there, holding a bottle of beer in his hand, his gaze especially bright in the dim light. He was two years younger than his sister, twenty-four, newly graduated from university, and currently unemployed at home. Broad shoulders and a narrow waist, handsome features, yet always carrying a trace of youthful laziness.
“Why aren’t you asleep yet?” Lin Wanqing put the bag on the table and walked toward him.
Lin Haoran put down his beer and stood up. Only half a meter separated them. The air suddenly grew thick.
“Waiting for you.” His voice was hoarse. “Today... I want to talk to you about something.”
Lin Wanqing's heart skipped a beat. For the past few months, her younger brother had been looking at her with increasingly strange eyes. Sometimes, when she came out of the shower with wet hair draped over her shoulders, he would stare at her collarbone for a long time; other times, when she was changing clothes and the door wasn't fully closed, he would 'coincidentally' pass by. She wasn't unaware of it; she had just been pretending not to know.
“What is it?” She tried her best to keep her voice steady.
Lin Haoran didn't answer. Instead, he suddenly stepped forward and grabbed her wrist. His palm was burning hot.
“Sis, I know this is wrong. But... I can’t take it anymore.”
Lin Wanqing wanted to pull her hand back, but didn't truly exert any force. She looked at her brother's face so close to hers, her heart pounding fiercely. The air smelled of beer, along with the faint masculine scent emanating from him.
“Hao Ran...”
Before she could finish speaking, he had already lowered his head and kissed her.
That kiss was tentative at first, filled with hesitation and nervousness. Lin Wanqing's body stiffened for a few seconds, then as if something ignited. She didn't push him away; instead, she slightly parted her lips. The moment their tongues intertwined, both let out suppressed gasps.
The kiss grew deeper and deeper. Lin Haoran's hand slid from her wrist to her waist, feeling her body temperature through her shirt. Lin Wanqing's hand also subconsciously climbed onto his shoulder.
The living room lights were still dim. They stumbled and fell onto the sofa. Lin Wanqing's short skirt was pushed up to the top of her thighs, Lin Haoran's hand slid up her smooth skin. She didn't stop him.
“Sis... is that okay?” he asked softly in her ear, his voice trembling.
Lin Wanqing closed her eyes and nodded.
That night, they crossed that line.
Clothes were taken off one by one. Lin Wanqing's body appeared exceptionally pale under the light, her breasts full, her waist slender. Lin Haoran's gaze almost burned through her. He lowered his head, his lips landing on her neck, collarbone, and then her chest. Lin Wanqing tilted her head back, her fingers threading through his hair.
When he entered her, both let out satisfied sighs. The movements were slow at first, cautious and exploratory, gradually becoming more intense. The sofa emitted faint creaks, mingling with their suppressed panting and the sound of flesh colliding.
After it ended, they lay quietly, neither speaking. Sweat glued their bodies together. Lin Wanqing's fingers lightly traced her brother's shoulder line, her mind in turmoil.
“Are we... insane?” she finally said.
Lin Haoran turned his head and kissed her forehead. 'Maybe. But I don't regret it.'
Since that night, the forbidden relationship spread like wildfire.
During the day, they were still normal siblings. Lin Wanqing went to work at the company, Lin Haoran prepared for interviews at home. At night, as long as their parents weren't there (their parents were often away on business), the apartment became their secret playground.
Sometimes it was after a meal, Lin Wanqing washing dishes, Lin Haoran hugging her from behind, hand reaching into her clothes to knead. She would be pressed against the countertop by him, skirt lifted, entered from behind. The sound of water covered their panting.
Sometimes it was midnight, Lin Haoran quietly sneaking into her room. The two tightly entangled under the covers, trying not to make a sound. Lin Wanqing would bite his shoulder to prevent herself from crying out.
Once, the parents suddenly returned early. The two were entangled on the sofa when they heard the key turning. They almost frantically separated and put on their clothes. Lin Wanqing's face was flushed like fire, and Lin Haoran's breathing hadn't yet calmed. The parents simply thought the siblings were watching TV and didn't suspect anything.
After that time, they became more cautious and also more addicted.
Once desire is ignited, it is hard to extinguish.
Lin Wanqing began to take the initiative. Sometimes she would deliberately wear thin clothes and walk around the house; sometimes she would push open the door while her brother was showering and stand under the spray with him. Hot water washed over their bodies as they pressed tightly together in the narrow space, the sound of the water covering everything.
Lin Haoran also grew bolder. When she came home late from work, he would press her against the wall in the entryway and enter her from behind. Her bag would fall to the floor, her high heels still on.
They tried all kinds of positions and all kinds of places—the living room, bedroom, kitchen, even the balcony (late at night, with the curtains drawn). After every climax, Lin Wanqing would lean in his arms and softly say, “If we keep doing this... what will happen later?”
Lin Haoran would always kiss her hair and reply, 'We'll worry about the future later. Right now, I just want you.'
Time passed day by day. Their relationship grew deeper and more dangerous.
Once, Lin Wanqing's colleague came to visit at home. After several rounds of drinks, the colleague went to the bathroom. Seizing the chance, Lin Haoran pulled his sister into the bedroom, quickly kissing her and slipping his hand under her skirt. Lin Wanqing almost cried out but still yielded to him. A few minutes later, they returned to the living room as if nothing had happened, their faces flushed unnaturally.
After the coworker left, the two immediately embraced and completely released the pent-up desire.
Once, they went to a hot spring hotel in the suburbs. When checking in, they said they were siblings, but they only took one room. At night, only the two of them were in the hot spring pool. The hot water steamed, and the mist spread everywhere. Lin Wanqing sat on his lap, facing him, slowly rising and falling. The rippling water covered the sounds of their coupling. Afterward, they leaned against the edge of the pool and looked at the night sky, wordless for a long time.
“If we get found out...” Lin Wanqing said softly.
“Then let’s bear it together.” Lin Haoran held her hand tightly.
After returning to the city, life went on. When their parents occasionally came back, they pretended to be the most normal siblings. But once the parents left, the apartment would turn into a battlefield of desire again.
Lin Wanqing began to feel she was changing. Her dependence on her brother grew deeper, not just physically but emotionally. Sometimes she wondered, if they weren't related by blood, could they be together openly? But reality was reality; blood ties couldn't be erased.
Lin Haoran was the same. He increasingly couldn't imagine life without his sister. He was absent-minded during job interviews, missing opportunities one after another. All he wanted was to see her and touch her every day.
One night, the two were entangled in bed until late at night. After it was over, Lin Wanqing lay in his arms and suddenly said, 'Haoran, should we stop?'
His body stiffened. "Why?"
"Because if this goes on... it’ll ruin us." Her voice was very soft. "Family, kinship, the future... it would all be ruined."
Lin Haoran was silent for a long time, then turned over and pressed down on her, looking into her eyes. 'But I can't stop. Can you?'
Lin Wanqing did not answer, but instead took the initiative to kiss him.
That night, they were more intense than ever before. As if trying to vent all their hesitation and fear. The bed frame shook violently, the sheets were grabbed and crumpled into a ball. When the climax came, Lin Wanqing cried out, not from pain, but from overly complex emotions.
In the days that followed, they never truly stopped. There were only occasional brief cooling-off periods. Once the cooling-off period passed, desire would surge back again.
Once, Lin Wanqing went on a business trip for a week. On the night she returned, Lin Haoran practically dragged her from the doorway into the room. Before her clothes were even fully off, he entered her. Pinned against the door by him, Lin Wanqing wrapped her legs around his waist, letting out suppressed moans.
"I’ve been waiting for you for so long..." he breathed low in her ear.
The longing of that entire week transformed into a frantic demand. They went at it until dawn, hardly closing their eyes.
A few months later, my parents suddenly announced that they were coming back to settle down here. Lin Wanqing and Lin Haoran were both thrown into panic. This meant they could no longer indulge themselves as before.
On the night before the parents returned, the two had done almost everything possible. From the living room to the bedroom, from the bathroom to the balcony, every corner bore traces of them. The last time, Lin Wanqing sat on top of him, moving slowly, but tears kept flowing uncontrollably.
"From now on... we can only be ordinary siblings." she said.
Lin Haoran held her tightly, saying nothing.
After the parents returned, the atmosphere at home changed. Lin Wanqing and Lin Haoran deliberately kept their distance, speaking to each other politely. But when their eyes met, desire still flickered.
Once late at night, their parents were already asleep. Lin Haoran quietly slipped into his sister's room. The two held each other tightly under the covers, trying to keep their movements as light as possible, but still couldn't help making slight sounds. After finishing, Lin Wanqing buried her face in his chest and whispered: 'This is too dangerous.'
"I know." He kissed her hair. "But I can't control myself."
After some time, Lin Haoran finally found a job and moved out. Lin Wanqing thought that way they could slowly cut off the relationship, but in fact, distance did not make the desire fade.
He would come back on weekends to “visit” his parents, but in fact he came to see her. Sometimes when the parents were not home, they would relive old dreams in the empty apartment. Sometimes when the parents were home, they would find an excuse to go out and get a hotel room.
In the hotel room, they could be more unrestrained. Lin Wanqing would actively ride him, letting him watch her rise and fall; or kneel by the bed, letting him enter from behind. After each time, they would lie together and talk for a long time. About work, the future, and those feelings that couldn't be spoken aloud.
“If we weren’t siblings……” Lin Wanqing once began like this.
Lin Haoran cut her off: 'But we are. So accept it.'
Time passed. Their forbidden relationship had lasted for nearly two years. From the initial panic to later habit, and now to dependence. Lin Wanqing sometimes wondered if she had already become unable to live without him.
One day, Lin Wanqing received a confession from an admirer. The other person was an excellent male colleague at the company with good qualifications. She hesitated for a long time but ultimately refused.
That night, she told Lin Haoran about it. After listening, he was silent for a long time, then pinned her down on the bed and entered her almost roughly.
"You are mine." He whispered in her ear, his voice carrying possessiveness.
Lin Wanqing did not refute. She lifted her leg, wrapped it around his waist, and matched his movements.
That night, they did it until they were exhausted.
The story is not over. Once the flame of taboo is ignited, it's hard to truly extinguish. Lin Wanqing and Lin Haoran continue forward in the crevice between blood ties and desire, sometimes feeling guilty, sometimes sinking into depravity, and sometimes feeling that this is the only reality they can grasp.
They knew this was wrong, and they knew it was dangerous. But every time their eyes met, every time their bodies touched, those rational warnings would be thrown to the back of their minds.
On a quiet afternoon, the parents went out for a walk. Only the two of them were left in the apartment. Lin Wanqing sat on the sofa, and Lin Haoran walked over, knelt before her, and buried his head in her bosom.
“Sis, give me one more time.” he said softly.
Lin Wanqing's fingers ran through his hair as she softly said, 'Okay.'
Then, everything started all over again.
She didn't ask further. Her fingers slid from his hair to the back of his neck, gently lifting his face. Their gazes collided at close range. The air held lingering coffee scent and rising body heat.
Lin Haoran kissed her first. This time there was no hesitation, only clear desire. Lin Wanqing responded quickly, their lips parting, tongues intertwining. The sofa was soft, and they soon shifted from sitting to half-lying. Her skirt was pushed up to her waist, his hand moving up from her inner thigh until it touched the already warm, damp fabric.
"Today... a little longer is okay." She said softly in the gap between breaths.
He nodded, but his movements did not slow because of it. One by one, the clothes were taken off and thrown onto the carpet. Lin Wanqing’s body looked especially white in the afternoon light, with faint shadows on her collarbones, chest, and waist hollow. Lin Haoran’s lips moved from the side of her neck all the way downward, lingering a long time on her nipples, gently grinding them with his teeth, then soothing them with the tip of his tongue. Her breathing grew ragged, and her fingers tightened on his shoulders.
As he entered, both of them let out a low sigh. The familiar tightness and warmth enveloped him, fitting perfectly as it had countless times before. Lin Haoran didn't rush to move; instead, he lay on top of her, his forehead against hers, feeling the subtle contractions of her inner walls.
“Do you miss me?” he asked.
Lin Wanqing did not answer, but instead lifted her leg and wrapped it around his waist.
The action started very slowly. Each time he withdrew, he almost completely came out before plunging back in to the hilt. The sofa made a faint sound, mixed with the sound of water and suppressed breaths. Lin Wanqing’s hand slid from his back to her buttocks, silently urging him on. He understood, and the pace gradually quickened. The sound of bodies colliding became clear, and her breasts swayed lightly with each impact.
The climax came earlier than expected. Lin Wanqing suddenly tensed, her inner walls spasming violently, burying her face in the crook of his shoulder, muffling all sounds in her throat. Lin Haoran, driven wild by her tight grip, forced himself to keep moving until the aftershocks of her climax subsided, then slowed to deep, heavy grinding.
They changed positions. Lin Wanqing lay across the back of the sofa, and he entered her from behind. From this angle he went in deeper, reaching the deepest part every time. Her fingers clutched the edge of the sofa, her back arched into a beautiful curve. With one hand, Lin Haoran held her waist; with the other, he reached around to knead that already swollen little nub. The double stimulation made her go again very quickly, her legs so weak she could hardly stay on her knees.
When the semen shot inside, his whole body pressed down on her back, his breath scorching hot. The two maintained the connected position for a long time until their heartbeats slowed down.
The parents would be back in about an hour.
They did not hurry to tidy up. Lin Wanqing leaned in his arms, lazily tracing the sweat on his chest with her fingers. The air-conditioning wind blew over their damp skin, bringing a faint chill.
“Next month I may be transferred to a branch office,” she suddenly said.
Lin Haoran paused his movements. 'How long?'
“At least half a year. They’re short-handed over there.”
The air was quiet for a few seconds. He didn't answer immediately, just held her tighter. His member, still buried inside her, swelled slightly again due to the emotional surge. Lin Wanqing felt it and gave a gentle squeeze.
“Go on.” He finally said. “Work is important.”
“Then we...”
"I’ll go over on the weekend. Or you come back." He kissed her hair. "There’s always a way.",
She didn't speak again, just took the initiative to move. This time she led, slowly grinding back and forth, letting what remained inside be pulled out and pushed back in. Pleasure built up prolonged and deep. During the second climax, Lin Haoran gasped and grabbed her hips, pressing her against himself. A large amount of fluid overflowed, trickling down her thighs.
When cleaning up the aftermath, the two moved quickly. Clothes were put on, the sofa was wiped clean, and the windows were opened for ventilation. Lin Wanqing took a short shower in the bathroom and came out with her hair still dripping. Lin Haoran leaned against the door waiting for her, his gaze dark and intense.
“Still want it?” she asked as she wiped her hair.
He walked over and pressed her against the sink, looking at her through the mirror. “There’s still enough time.”
She looked at herself in the mirror—cheeks flushed, lips slightly swollen, fresh hickeys on her collarbone. Then she nodded.
This time they did it standing. Lin Wanqing braced her hands on the countertop as he entered from behind, the mirror faithfully reflecting every detail. The sounds of water, impact, and suppressed moans echoed in the bathroom. By the end, her legs were trembling, and only his arm around her waist kept her from collapsing.
When the parents returned, the apartment had already returned to its usual state. Lin Wanqing was cutting fruit in the kitchen, Lin Haoran sat in the living room looking at his laptop. They occasionally exchanged glances, their eyes still holding a lingering heat, but no one spoke of it.
After dinner, my parents went for a walk. Once again, only the two of them were left in the room.
This time there was no frantic tearing of clothes. Lin Wanqing proactively sat on his lap, the straddling position allowing for deep penetration. Her arms wrapped around his neck, her forehead pressed against his, as she moved up and down on her own. The movements were slow, yet each one went all the way to the hilt. Lin Haoran's hands supported her waist, his thumbs pressing against her hip bones, feeling her rhythm.
“This seems... more like lovers.” she said breathlessly.
“We already are.” he replied.
She smiled, the smile carrying bitterness and resignation. Then she quickened her pace until they both reached the peak together.
For the days after that, both parents were home. They could only connect briefly in the dead of night, with minimal movement. Once, when Lin Wanqing climaxed because of him, she bit her own hand, leaving a faint tooth mark. The next day at dinner, when her mother asked with concern, she only said she had accidentally bumped it.
The transfer order came down faster than expected.
On the day Lin Wanqing was packing her luggage, Lin Haoran helped her move the boxes. The two of them were in her room, with the door closed. Their parents were watching TV in the living room. He hugged her from behind, his hand slipping under her T-shirt, his palm pressed against her skin.
"Stay tonight," he said in her ear.
She did not refuse.
At night, after our parents fell asleep, he crept into her room. This time they tried to be as quiet as possible, but still went on until very late. Lin Wanqing sat on top of him, facing away, controlling the depth and speed herself. His hands reached around from behind, covering her breasts, gently kneading them in rhythm with her movements. When it ended, she collapsed softly into his arms, both of them covered in a thin layer of sweat.
“When you go over there... will you miss me?” he asked.
“Will.” She answered honestly, “My body will too.”
He chuckled lowly and bit her shoulder. “That’s good.”
On the morning of parting, the two of them faced each other at the entryway for a few seconds. Their parents were nearby reminding them of things to pay attention to, completely unaware of that subtle tension in the air. Lin Wanqing picked up her suitcase and nodded at him. He nodded back.
After the car door closed, Lin Haoran stood in place watching for a long time.
Life at the branch office was busier than I had imagined.
Lin Wanqing quickly adapted to the new rhythm: meetings, visiting clients, writing reports during the day, often returning to the rented apartment very late at night. For the first week, she hardly contacted him proactively. Until one night when she was working overtime until ten, staring at the computer screen, she suddenly felt an emptiness in her heart.
The message was simple: "You there?"
The reply came almost instantly: 'Here. Video?'
She hesitated for a few seconds, then still clicked 'Agree'.
The screen lit up, and Lin Haoran's face appeared on the other side. The background was her familiar bedroom. He looked like he had just showered, his hair still wet.
“Do you miss me?” he got straight to the point.
Lin Wanqing did not deny it. The two of them looked at each other in silence for a moment, then she suddenly said, 'Take off your clothes.'
He froze for a moment, then did as told. On the other end of the screen, his body gradually became exposed. Lin Wanqing watched, her breathing slowly growing heavier. She also began unbuttoning her own clothes, taking them off one by one until only her underwear was left.
"Continue," she said.
That night, they went at it for a long time through the screen. Lin Wanqing leaned against the headboard, legs apart, her fingers moving according to his instructions. His voice was low, carrying clear commands and suppressed gasps. When she climaxed, he was almost simultaneous. Afterwards, both were panting, but the silence on both sides of the screen was unexpectedly calm.
“I’ll go over next week,” he finally said.
“Good.”
We really met on a Friday night.
Lin Haoran took a four-hour high-speed train directly to her rental apartment. As soon as the door opened, they kissed. Luggage was tossed aside at the entrance, clothes discarded all the way from the living room to the bedroom. This time, there was no restraint, no caution. Lin Wanqing was pressed onto the bed by him, her legs spread wide, enduring an almost fierce entry. Her cries no longer needed to be suppressed, each one echoing against the walls.
“This past week... I’ve missed you to death.” he said as he thrust.
She couldn't answer, could only respond with her body.
That night they hardly slept. From the bed to the floor, from the window to the shower. Hot water washed over their entwined bodies, the sound of water masking all moans. Lin Wanqing was lifted by him, her back against the tiles, her legs wrapped around his waist. This position penetrated extremely deeply, each thrust making her toes curl.
Over the weekend, they hardly went out. Food was delivered, and the curtains remained drawn. Their physical compatibility reached new heights after their separation. Lin Wanqing would actively kiss him after climax, would tighten forcefully when he ejaculated, and would lazily lie on top of him afterward, listening to his heartbeat.
On Sunday afternoon, it was time for him to go back.
The two stood at the door and fell into silence once again. There were still fresh kiss marks on Lin Wanqing's collarbone, barely covered by her collar. Lin Haoran's fingers had lingered at her waist for a long time.
“Next month……I’ll come again,” he said.
She nodded. "Or I'll go back for a while."
No lingering hugs. After the door closed, the rental apartment fell quiet again. Lin Wanqing leaned against the door, closed her eyes for a moment, then went to tidy the rumpled bedsheet.
Distance did not dilute desire; instead, it made each meeting more intense.
They began to get used to this pattern: maintaining things through video and voice calls at ordinary times, meeting once every few weeks, and releasing all the pent-up desire in one go. Sometimes he came over, sometimes she went back. Hotels, rented rooms, even the home when the parents were away became their temporary territory.
Once when she went back, her parents happened to be there. The two could only interact like ordinary siblings, but at night, they lay in their own rooms, continuing their unfinished conversation via text messages. Until 2 a.m., Lin Haoran still sneaked into her room. The movements had to be extremely light, and breathing had to be extremely slow. Lin Wanqing bit the pillow, enduring his as-silent-as-possible thrusts. After it was over, he didn't leave immediately but held her and lay there for a long time.
“This is too dangerous.” she said in the dark.
"I know." He kissed the back of her neck. "But I don't want to stop."
She didn't try to persuade him again. Just held his hand in return, fingers interlaced.
Time continued to move forward.
Lin Wanqing performed well at the branch company, making it possible for her to stay. Lin Haoran's work was also gradually stabilizing. Their life paths seemed to be becoming clearer, yet that hidden thread always kept them entwined.
Once during a video call, Lin Wanqing suddenly asked: 'If we keep going on like this, what will we be like in ten years?'
Lin Haoran on the other side of the screen was silent for a few seconds. 'I don't know. Maybe it will still be like this. Maybe one day it will just naturally stop.'
“Do you want to stop?”
“No.” He looked at her, his gaze steady. “What about you?”
Lin Wanqing did not answer. She simply adjusted the camera angle to give him a clearer view. Then she began to undo her clothes.
Everything returns to the most direct instinct.
Desire, blood ties, familial affection, possession—these complex things were entangled between them. No one could provide a perfect answer, nor did anyone truly want an answer.
They simply chose to draw closer again and again, to confirm within each other’s bodies that at least for this moment, they were still together.
And as long as it can continue, let it continue.
Until one day, life pushes them apart with stronger force, or they finally choose to let go themselves.
Before that, all the nights, all the gasps, all the secret climaxes belonged to the two of them.
Belonging to this desire woven from blood ties, with no way back.
