The night was as dark as ink, and the city's lights glittered 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, took off her high heels, her long hair loose over her shoulders. She was twenty-six this year, tall and slender, with fair skin, wearing a simple white shirt and black short skirt, yet unable to hide the curves of a mature woman. The living room lights were off, 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, 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, just graduated from college, and currently unemployed at home. Broad shoulders, a narrow waist, handsome features, yet always carrying a hint of youthful laziness.
“Why aren’t you asleep yet?” Lin Wanqing put the bag on the table and walked over to 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. In recent months, her brother's gaze towards her had become increasingly off. Sometimes when she came out of the shower, hair wet, he would stare at her collarbone for a long time; sometimes when she changed clothes, the door not fully closed, he would "coincidentally" pass by. She wasn't unaware, just had been pretending not to know.
“What is it?” she tried to keep her voice steady.
Lin Haoran didn't answer. 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 force. She looked at her brother's face so close, her heart pounding fiercely. The air smelled of beer, and the faint masculine scent from him.
“Hao Ran...”
Before he could finish speaking, he had already lowered his head and kissed her.
That kiss was tentative at first, carrying hesitation and nervousness. Lin Wanqing's body stiffened for a few seconds, then seemed to ignite something. 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 heat through her shirt. Lin Wanqing’s hand also unconsciously rested on his shoulder.
The living room lights remained dim. They stumbled and fell onto the sofa. Lin Wanqing's short skirt was pushed up to the top of her thighs, and Lin Haoran's hand slid up her smooth skin. She didn't stop him.
“Sister... can I?” he asked in a low voice by her ear, his voice trembling.
Lin Wanqing closed her eyes and nodded.
That night, they crossed that line.
The clothes were taken off one by one. Lin Wanqing's body appeared exceptionally fair under the light, with full breasts and a slender waist. Lin Haoran's gaze was almost burning through her. He lowered his head, his lips landing on the side of her neck, her collarbone, and then her chest. Lin Wanqing tilted her head back in unbearable desire, her fingers threading through his hair.
When he entered her, both of them let out sighs of satisfaction. The movements were slow at first, careful and tentative, gradually becoming intense. The sofa emitted faint creaking sounds, mixed 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 younger brother's shoulder line, her mind in turmoil.
"Are we... crazy?" she finally said.
Lin Haoran turned his head and kissed her forehead. 'Maybe. But I don't regret it.'
Starting that night, the forbidden relationship spread like wildfire.
During the day, they are still normal siblings. Lin Wanqing goes to work at the company, Lin Haoran prepares for interviews at home. At night, as long as their parents are not around (their parents are often away on business), the apartment becomes their secret playground.
Sometimes after a meal, Lin Wanqing washes the dishes, and Lin Haoran hugs her from behind, his hand reaching into her clothes to fondle. She would be pressed against the countertop by him, her skirt lifted, entered from behind. The sound of water masks their panting.
Sometimes in the middle of the night, Lin Haoran quietly slips into her room. The two tangle tightly under the blanket, trying not to make a sound. Lin Wanqing bites his shoulder to keep herself from crying out.
Once, their parents suddenly returned early. The two were entangled on the sofa when they heard the sound of keys 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 down. Their 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 difficult 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 the door open while her brother was showering and stand under the shower with him. Hot water washed over their bodies, they pressed tightly together in the narrow space, the sound of 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 drop to the floor, her high heels still on.
They tried all kinds of positions and all kinds of places—the living room, the bedroom, the kitchen, even the balcony (late at night, with the curtains drawn). After every climax, Lin Wanqing would lean against his chest and softly say, “What are we going to do like this... in the future?”
Lin Haoran would always answer while kissing her hair, '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 over for a visit. After a few rounds of drinks, the colleague went to the restroom. Lin Haoran seized the chance to pull his sister into the bedroom, quickly kissing her and slipping his hand under her skirt. Lin Wanqing almost cried out but still responded to him. A few minutes later, they returned to the living room as if nothing had happened, their faces flushed unnaturally.
After the colleague left, the two immediately embraced and completely released the pent-up desire.
Another time, they went to a hot spring hotel in the suburbs. At check-in they said they were siblings, but they only booked one room. At night, only the two of them were in the hot spring pool. The hot water steamed, the mist filled the air. Lin Wanqing sat on his lap, facing him, moving slowly up and down. The ripples on the water concealed the sounds of their lovemaking. Afterward, they leaned against the edge of the pool and looked at the night sky, silent for a long time.
"If we get discovered..." Lin Wanqing said softly.
“Then let’s bear it together.” Lin Haoran tightened his grip on her hand.
After returning to the city, life went on. My parents occasionally came back, and they would pretend to be the most normal siblings. But once my parents left, the apartment would once again become a battlefield of desire.
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, would they be openly together? 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. He just wanted to see her, to touch her every day.
One night, the two were entangled in bed again until late. Afterwards, Lin Wanqing lay in his arms and suddenly said, 'Haoran, should we stop?'
His body stiffened. “Why?”
“Because if this keeps going... it’ll destroy us.” Her voice was very soft. “Family affection, family, the future... everything will be ruined.”
Lin Haoran was silent for a long time, then he rolled over, pinning her beneath him, and looked into her eyes. 'But I can't stop. Can you?'
Lin Wanqing did not answer, she just took the initiative and kissed him.
That night, they were more intense than ever before. It was as if they wanted 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 because of pain, but because of overly complex emotions.
In the days that followed, they never truly stopped. It was just that occasionally there would be a brief cooling-off period. Once that period passed, desire would surge back again.
Once, Lin Wanqing went on a business trip to another city for a week. On the night she returned, Lin Haoran practically dragged her from the doorway into the room. Before their clothes were even fully off, he entered her. Lin Wanqing was pressed against the door by him, her legs wrapped around his waist, letting out suppressed moans.
“I’ve been waiting for you for so long...” He panted softly in her ear.
All the longing from that week turned into a frenzy of taking. They went at it until dawn, hardly closing their eyes.
Several more months passed, and my parents suddenly announced that they were coming back to settle down. Lin Wanqing and Lin Haoran both fell into panic at the same time. This meant they could no longer indulge themselves as they had before.
The night before their parents came back, the two of them almost did everything they could. From the living room to the bedroom, from the bathroom to the balcony, every corner bore their traces. For the last time, Lin Wanqing sat on top of him and moved slowly, yet tears kept flowing uncontrollably.
“From now on… we can only be ordinary siblings.” she said.
Lin Haoran held her tight without saying a word.
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 would still flash.
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 faint 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 more time passed, Lin Haoran finally found a job and moved out. Lin Wanqing thought this would slowly sever the relationship, but the facts proved that distance did not make desire fade.
On weekends he would come back to “visit” his parents, but in fact he was coming to see her. Sometimes the parents were away, and they would relive old dreams in the empty apartment. Sometimes the parents were there, and they would find an excuse to go out and check into a hotel.
In the hotel room, they could be more unrestrained. Lin Wanqing would take the initiative to ride on top of him, letting him watch her rise and fall; or kneel by the bed, letting him enter from behind. After each time ended, they would lie together, talking for a long time. Talking about work, about the future, about those feelings that couldn't be spoken aloud.
"If we weren’t siblings..." Lin Wanqing once began like that.
Lin Haoran cut her off, 'But we are. So accept it.'
Time passed. Their forbidden relationship had lasted 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 leave him.
One day, Lin Wanqing received a confession from a suitor. The other party 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 this. After listening, he remained silent for a long time, then pressed her onto the bed, entering her almost roughly.
“You are mine.” he whispered in her ear, his voice carrying a possessive desire.
Lin Wanqing did not refute. She lifted her leg, wrapped it around his waist, and matched his movements.
That night, they did it until exhausted.
The story is not over. Once the forbidden flame is ignited, it is difficult 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 with every glance exchanged and every touch of their bodies, those rational warnings were 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 chance.” he said gently.
Lin Wanqing's fingers ran through his hair as she whispered softly, 'Okay.'
Then, everything started all over again.
She didn't ask any more questions. Her fingers slid from his hair to the back of his neck, gently applying force to lift his face. Their gazes collided at close range. The air held the lingering scent of coffee and gradually 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 entwining. 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, touching the already damp and warm fabric.
“Today... can be a little longer.” She said in a low voice between breaths.
He nodded, but his movements did not slow down because of it. One piece of clothing after another was stripped off and thrown onto the carpet. Lin Wanqing’s body looked especially pale in the afternoon light, and her collarbones, chest, and hollow waist all carried faint shadows. Lin Haoran’s lips moved from the side of her neck all the way downward, lingering for a long time at her nipples, gently grinding with his teeth before soothing her with the tip of his tongue. Her breathing turned ragged, and her fingers gripped his shoulders tightly.
As they entered, both let out a soft sigh. The familiar tightness and warmth enveloped him, fitting together perfectly as they had countless times before. Lin Haoran didn't rush to move; instead, he lay on top of her, forehead pressed against hers, feeling the subtle contractions of her inner walls.
"You miss me?" he asked.
Lin Wanqing did not answer, she just lifted her leg and wrapped it around his waist.
The motion started very slowly. Each withdrawal was almost completely out before plunging back in to the hilt. The sofa gave off a faint sound, mixed with splashing water and suppressed gasps. Lin Wanqing's hand slid from his back to his buttocks, silently urging him on. He understood, and the pace gradually quickened. The sound of bodies colliding became clearer, and her breasts swayed gently with the impacts.
The climax came earlier than expected. Lin Wanqing suddenly tensed up, her inner walls spasming violently. She buried her face in the crook of his shoulder, muffling all sounds in her throat. Lin Haoran, squeezed until his scalp tingled, forced himself to keep moving until the aftershocks of her climax subsided, then slowed to a deep, heavy grind.
They changed positions. Lin Wanqing lay across the back of the sofa, and he entered her from behind. This angle went in deeper, each time reaching the deepest part. Her fingers gripped the edge of the sofa tightly, her spine arching into a beautiful curve. Lin Haoran supported her waist with one hand and reached around to the front with the other, rubbing that already swollen little nub. The double stimulation quickly drove her to another climax, her legs so weak she could hardly stay on them.
When the semen shot inside, he pressed his entire body against her back, his breath scorching hot. They maintained the connected position for a long time, until their heartbeats slowed down.
The parents will probably be back in about an hour.
They did not rush to clean up. Lin Wanqing leaned against his chest, lazily tracing the sweat on his chest with her fingers. The air-conditioning breeze blew across their damp skin, bringing a faint chill.
“Next month I may be transferred to the 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 fell silent for a few seconds. He didn't answer immediately, just held her tighter. His member was still buried inside her, swelling slightly again due to the emotional turmoil. Lin Wanqing felt it and gently contracted.
“Go on.” he finally said, “Work is important.”
“Then we…”
“I’ll come over on the weekend. Or you come back.” He kissed her hair. “There’s always a way.”
She didn't speak again, just started moving on her own. This time she took the lead, slowly grinding back and forth, letting what remained inside be pulled out and pushed back in. Pleasure built up long and deep. When he ejaculated for the second time, Lin Haoran gasped, grabbed her buttocks, and pressed her against himself. A large amount of fluid overflowed, trickling down her thighs.
While cleaning up the mess, the two moved quickly. Clothes were put on, the sofa was wiped clean, and the windows were opened for ventilation. Lin Wanqing took a quick shower in the bathroom and came out with her hair still dripping. Lin Haoran leaned against the door waiting for her, his eyes dark.
"Still want more?" she asked, wiping her hair.
He walked over and pinned her against the washstand, looking at her through the mirror. “There's still enough time.”
She looked at herself in the mirror—her cheeks flushed, her lips slightly swollen, fresh hickeys on her collarbone. Then she nodded.
This time, they finished standing up. Lin Wanqing braced her hands on the countertop as he entered from behind. The mirror faithfully reflected every detail. The sounds of water, impact, and suppressed moans echoed in the bathroom. When it ended, her legs were trembling; she would have collapsed if he hadn't held her by the waist.
When the parents returned, the apartment had already returned to its usual state. Lin Wanqing was cutting fruit in the kitchen, and Lin Haoran was sitting in the living room looking at his laptop. Occasionally, they would glance at each other, their eyes still holding a lingering heat, but no one spoke of it.
After dinner, the parents went for a walk. Once again, only the two of them were left in the room.
This time, there was no frantic tearing. Lin Wanqing actively sat on his lap; the straddling position allowed for deep penetration. Her arms wrapped around his neck, her forehead pressed against his, as she moved up and down herself. The movements were slow, yet each one went all the way in. Lin Haoran's hands supported her waist, his thumbs pressing against her hip bones, feeling her rhythm.
“This seems... more like lovers.” she said, panting.
"We already are." he replied.
She smiled, the smile tinged with bitterness and resignation. Then she quickened her pace until they both reached the peak together.
In the days that followed, both parents were home. They could only connect briefly late at night, with minimal movement. Once, when Lin Wanqing climaxed because of him, she bit her own hand, leaving a shallow tooth mark. The next day at dinner, when her mother asked concernedly, she just said she 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 boxes. The two 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 the parents had gone to sleep, he slipped into her room. This time they tried to be as quiet as possible, but still went on until very late. Lin Wanqing sat on him, facing away from him, controlling the depth and speed herself. His hand reached around from behind, covering her breasts, and gently kneaded them in time with her movements. When it was over, she went limp in his arms, and both of them were covered in a thin layer of sweat.
“When you go there... will you miss me?” he asked.
“Yes.” she answered honestly, “my body will too.”
He chuckled softly, biting her shoulder. “That's good.”
On the morning of their parting, the two stood at the entryway and looked at each other for a few seconds. His 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 during the day, visiting clients, writing reports, often returning to the rental apartment very late at night. In the first week, she hardly contacted him proactively. Until one night when she worked overtime until ten, staring at the computer screen, she suddenly felt an emptiness in her heart.
The message was very simple: "Are you there?"
The reply came almost instantly: "Here. Video?"
She hesitated for a few seconds, then 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 taken a shower, his hair still wet.
"You miss me?" he asked outright.
Lin Wanqing did not deny it. The two stared 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 screen, his body gradually came into view. Lin Wanqing watched, her breathing growing heavier. She also began unbuttoning herself, taking off one piece after another, until she was left in her underwear.
“Continue.” she said.
That night they did 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 did almost simultaneously. After finishing, both were panting a little, yet the silence on both sides of the screen was unexpectedly calm.
"I'll come over next week," he said at last.
“Good.”
They 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, bearing his almost fierce entry. Her cries no longer needed to be suppressed, each one hitting the walls.
“I’ve missed you so much this past week…” he said as he thrust in and out.
She couldn’t answer, so she 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 went extremely deep, each thrust making her toes curl.
For the two weekend days, they hardly went out at all. Food was delivered, and the curtains stayed drawn. Their physical compatibility rose to a new level after their separation. Lin Wanqing would主动 kiss him after climax, would clench tightly when he came, and afterwards would lazily lie on top of him, listening to his heartbeat.
On Sunday afternoon, he should be heading back.
The two stood at the doorway and fell silent again. There were still fresh kiss marks on Lin Wanqing’s collarbone, barely hidden 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 room fell quiet again. Lin Wanqing leaned against the door, closed her eyes briefly, then went to tidy the messy bedsheets.
Distance did not dilute desire; instead, it made every meeting more intense.
They began to get used to this pattern: keeping things going through video and voice chats in daily life, then meeting once every few weeks to release all the accumulated desire at once. Sometimes he came over, sometimes she went back. Hotels, rental rooms, and even the home when the parents were away all became their temporary territory.
Once when she went back, her parents happened to be home. The two could only interact like ordinary siblings, but at night, lying in their separate rooms, they continued their unfinished conversation via text messages. Until 2 a.m., Lin Haoran still slipped into her room. Movements had to be extremely quiet, breathing had to be extremely slow. Lin Wanqing bit the pillow, enduring his as-silent-as-possible thrusts. After finishing, 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. She just reached back and held his hand, 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 gradually stabilizing. Their life trajectories seemed to be becoming clearer, yet only that hidden thread always kept them entangled together.
Once during a video call, Lin Wanqing suddenly asked, 'If we keep going 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?”
“I don’t hope so.” He looked at her, his gaze steady, “What about you?”
Lin Wanqing did not answer. She simply adjusted the angle of the camera so he could see more clearly. Then she began to undo her clothes.
Everything returned once again 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, and no one truly wanted an answer.
They simply chose to draw close again and again, confirming within each other's bodies that, at least in this moment, they were still together.
And as long as it can continue, let it continue.
Until one day, life pushes them apart with a stronger force, or they themselves are finally willing to let go.
Before that, all the nights, all the gasps, all the secret climaxes belonged to just the two of them.
Belonging to this desire woven by blood, with no way back.
