The autumn nights on campus always come quietly.
Long Yu is a senior medical student. During the day, he interns at the affiliated hospital, and at night, he occasionally spends time in the campus forum chat room. His chosen ID is 'Dr. Lust'—half self-deprecating, half a joke.
That night, he couldn't sleep and entered a chat room. Not long after, a line of text popped up on the screen.
Senior: Hello, are you really a medical student?
Long Yu: Yes, I'm a senior in medical school. Is there something?
Senior: So which medical specialty are you focusing on now?
Long Yu: I'm quite interested in the proctology direction and have been doing internships with my teacher recently.
Senior Sister: "...So you often come into contact with related examinations?"
Long Yu: I assist during internships, but formal procedures aren't my responsibility yet.
Senior: Then... if a classmate privately asks you some embarrassing questions, would you help take a look?
Long Yu: It depends. If someone is genuinely uncomfortable, I'd suggest going to a proper clinic. Of course, if they just want to learn the correct methods, I can also talk about that.
Senior: You're quite serious.
Long Yu: Mutual respect, you know. By the way, I haven't asked which college you're from?
Senior: I'm a second-year graduate student, School of Management. I'm twenty-five this year. And you?
Long Yu: Twenty-two. Not graduated yet.
Senior: Then have you ever been in a relationship?
Long Yu: I've been in a relationship, but we broke up. I'm quite busy now.
Senior Sister: "...Actually, I have something I want to ask. About... later. My boyfriend sometimes wants to try, but last time it made me very uncomfortable, and it still hurts a bit."
Long Yu: Sounds like insufficient preparation. If you're willing, I can explain the correct steps and precautions to you following proper procedures.
Senior Sister: "...Okay."
He explained it very carefully: lubrication, stretching, rhythm, breathing, when to stop. As the other person listened, their tone clearly softened.
Senior: You explained it so clearly, now I'm actually more nervous, and a little... curious.
Long Yu: If you're really uneasy, you can come to the school clinic. I'm on duty at the Student Health Center this semester; Friday nights are quiet. If you're willing, I can check your recovery for you—purely an examination.
Senior: ...Really just a check-up?
Long Yu: If you say stop, we stop. Anytime.
Senior: Then... tomorrow afternoon at 5:30, Health Center, Examination Room 3?
Long Yu: Okay. My name is Long Yu. Call me when you arrive.
The next day was Friday. After the campus infirmary closed, only the student on duty remained. Long Yu arrived early at examination room number three, preparing everything that needed to be ready. At 5:25, his phone rang.
“I’m Wang Xuan. Downstairs.”
He went downstairs to pick her up. Wang Xuan was wearing a simple white shirt and a skirt, her long hair tied up neatly, looking a little colder than when they chatted. The two of them went into the consulting room one after the other, and the door closed gently.
"It's right here." Long Yu pointed at the examination bed. "If you regret it, you can still leave now."
Wang Xuan shook her head, her voice a bit low: "I want to figure it out. Also... want to try the feeling you mentioned."
She turned around, unbuttoned her dress herself, and pulled down her panties along with it. Her movements were somewhat stiff but didn't stop. Long Yu didn't approach immediately, instead asking first:
“Can I touch you?”
She nodded.
“Lie on top of me, lower your waist a little. If it feels uncomfortable, say so.”
Wang Xuan complied. Long Yu put on gloves, applied lubricant, and first slowly inserted one finger. Her body visibly tensed, her fingers gripping the sheets.
“Breathe. Count with me.”
As he said this, he gently kneaded and pressed her tailbone. Only after she adjusted did he add two fingers and slowly widen her. In the air there was only the faint sound of water and her suppressed breathing.
“Are you okay?”
“...It swelled, but not as painfully as last time.”
Long Yu withdrew his fingers, put on protection, and applied more lubricant. When the glans pressed against the entrance, he confirmed again:
“Want to continue?”
“Yes.”
He entered very slowly. After fully going in, he stopped and waited until her breathing steadied again before beginning shallow thrusts. At first Wang Xuan buried her face in the crook of her arm, but later gradually lifted her waist, matching his rhythm.
“A little… deeper.”
Long Yu held her hip with one hand, while the other reached around to the front, gently rubbing her already moist spot. The dual stimulation quickly made her tense up, her back hole contracting in waves. When she climaxed, her whole body trembled, but she didn't make a sound, only biting her lower lip hard.
Long Yu did not finish immediately. He slowed his movements, waiting for her to recover from the aftershocks before continuing. The second time, she actively lowered her hips further, and her voice finally escaped:
“Long Yu…… I……”
He came when she was approaching the peak for the third time, all of it shooting into the condom. Afterward he helped her clean up, carefully wiping her with a warm towel, and then helped her put on her clothes one piece at a time.
Wang Xuan sat on the edge of the bed, her hair slightly messy, but her eyes were bright.
“So it really can be painless.”
Long Yu threw the gloves into the trash can and leaned against the desk, looking at her.
"If you still want it next time, say so in advance. Or... we can change places, not here."
She was silent for a few seconds, then suddenly reached out and tugged at the corner of his clothes.
“The dorm is too far. The place you rented... is it okay?”
Long Yu nodded.
Starting that night, they had a fixed Friday. Sometimes it was the consultation room after duty at the health center, sometimes it was a single room outside Long Yu’s school. Wang Xuan would take the lubricant initiative to bring it, kneel on the bed herself, and look back at him.
“I want you to cum inside today. Then I’ll clamp it in and go back.”
Long Yu complied. When she dressed and left, her steps were somewhat unsteady, but she wore a satisfied smile.
On campus, they were still ordinary senior and junior. Saving seats together in the library, eating together in the cafeteria, occasionally walking by the lake. Only they knew that those nights wrapped in bedsheets and condoms were their most genuine closeness.
Once after finishing, Wang Xuan leaned against his chest, her fingers unconsciously tracing circles.
“Where are you going after graduation?”
“Top three in this city, continue on to graduate school.”
“Then……can we continue?”
Long Yu held her hand, brought it to his lips, and kissed it.
“I can. As long as you’re willing.” The cicadas outside the window gradually grew sparse; autumn was about to pass. And they both knew that once some secrets began, they would not end easily. That examination bed in the campus infirmary became the first witness, and also the scorching starting point they would recall again and again in countless nights thereafter.
When autumn completely passed, the ginkgo leaves on campus began to fall in large swathes.
The relationship between Long Yu and Wang Xuan developed more naturally than either had anticipated. During the day, they remained ordinary senior and junior—the window seat in the library was always reserved in advance by Long Yu, and Wang Xuan would bring two cups of hot soy milk when she arrived; they occasionally bumped into each other in the cafeteria line, exchanging a smile before returning to their respective circles. No one knew that every Friday night, the door to examination room No. 3 in the health center would reopen after 9 p.m.
The first time meeting outside the clinic was at Long Yu's rented place off-campus.
When Wang Xuan arrived, she brought a small umbrella, a few strands of her hair dampened by the rain. After entering, she didn't speak immediately, just leaned the umbrella against the wall, then turned and looked at him.
“No need for a checkup today.” she said softly, “I want you.”
Long Yu pulled her into his embrace. This time, there were no gloves, no smell of disinfectant from the examination bed, only the lingering scent of rain on both of them. Clothes fell to the floor one by one. Wang Xuan actively straddled his lap, guiding him as she slowly lowered herself. The moment he entered, both let out soft gasps. Her back hole was already familiar with his shape, yet it remained tight enough to make his scalp tingle.
She began to move up and down on her own, hands braced on his shoulders, but her gaze remained fixed on him. Long Yu tilted his head up to kiss her, his palm sliding up from her waist to cover her breast. Her nipple quickly hardened under his fingertips. Wang Xuan's rhythm faltered for a moment, her inner walls contracting. She buried her face in the crook of his neck, her voice trembling:
"Slower... it's too full..."
But he still didn’t really slow down. Instead, he supported her hips and thrust upward. Each time went in to the deepest point. Wang Xuan quickly climaxed, her body tensed tightly, her back passage clenching him deathly hard. Long Yu忍 endured without releasing immediately, and only after she recovered did he lay her down on the bed and enter from behind.
This position goes in even deeper. Wang Xuan buried her face in the pillow, her fingers gripping the bedsheet tightly. Long Yu leaned down, his chest against her back, one hand reaching around to the front to rub her clitoris, while whispering in her ear:
"Do you still want me to finish inside?"
She nodded, her voice already hoarse: "Want... to give it all to me."
At the final push, she came again. The warm liquid poured fully into the deepest place. The two of them remained in that connected position for a long time, until even their breathing calmed down.
Since then, Friday was no longer the only day we met.
Sometimes Wednesday afternoons, Wang Xuan has no class and goes directly to Long Yu's rented room. Sometimes weekends, the two spend the whole day in the room. After cumming inside her once, Long Yu would use his fingers to scoop out the semen bit by bit, then smear it on her nipples, watching her blush with shame and excitement. Wang Xuan would also, when his eyes ached from writing his thesis, suddenly kneel down, take his thing into her mouth until fully hard, then turn around herself, presenting her back hole to him.
“I want the back today.” She always said it that way, in the same tone as ordering a regular coffee.
Campus life remained mundane. During finals week, they pulled all-nighters in the library together; Long Yu handled medical literature, Wang Xuan worked on her management models. When tired, she would rest her head on his shoulder, pretending to be just ordinary senior and junior. But whenever no one was around, Long Yu's hand would quietly cover the inside of her thigh, fingertips gently pressing through her pants. Wang Xuan never avoided it, just raised her book a little higher to hide her slightly reddened ear tips.
Once in the farthest corner study room of the library, after closing time, only the two of them remained. Long Yu pressed her between the bookshelves and entered her from behind. Wang Xuan braced her hands against the shelves, trying hard not to make a sound, but each time he thrust deepest, faint whimpers still escaped. He reached around to rub her clit, gradually speeding up. When she came, her whole body tensed, her inner walls tightly gripping him. Long Yu bit her shoulder and came inside her completely.
Afterward he helped her get her clothes in order, then draped his own coat over her shoulders. The two of them walked out of the library one after the other, as if nothing had happened.
When winter came, Wang Xuan began staying over more frequently.
One snowy night, nestled in his arms, she suddenly spoke:
“My boyfriend... we broke up.”
Long Yu's hand rested on her hair.
“Because what?”
“He said I’ve been too cold lately. Actually, it’s because whenever he touches me, I can’t stop thinking about you.” Wang Xuan raised her head and looked into his eyes. “I didn’t tell him about you. I only said I might not be able to continue this relationship.”
Long Yu did not answer immediately. He simply held her tighter, but his lower body had already hardened. Wang Xuan felt it and chuckled softly, then actively straddled him. This time, without much preparation, she lowered herself onto him.
“I want the front today.” she said, “and I want the back too. I want both.”
That night they did it for a long time. First, she was on top moving by herself, her nipples swaying before his eyes with each rise and fall. Later, he flipped her over and pinned her beneath him, entering from the front, hitting the deepest point every time. After she climaxed until her legs went weak, he had her lie on her stomach and entered from behind again. Wang Xuan had completely adapted to his size, her inner walls wet and hot, each withdrawal producing a sticky, wet sound.
“Long Yu……” she called his name, her voice halting, “cum inside…… I want to sleep with your stuff in me.”
He did as told. When the semen was ejaculated in, she trembled again slightly, and her back passage subconsciously tightened, as if trying to keep everything in.
Afterward, the two lay side by side, and the snow outside the window was still falling. Wang Xuan’s fingers traced circles on his chest, and then she suddenly said:
“When you graduate next year, I’ll continue on to a PhD. I’ll still be at this school.”
“So?”
“So we can continue.” She turned around and faced him directly. “No need to hide in the clinic anymore, and no need to pretend we’re just senior and junior students. I want it to be more formal.”
Long Yu looked into her eyes for a long time.
Then he kissed her.
It wasn’t the kind of kiss from before, full of desire, but a very slow, very deep one. By the time the kiss ended, he was hard again. Wang Xuan felt the heat pressing between her legs and said nothing, only lifting one leg to let him enter again.
This time, they did it particularly slowly, as if trying to say all the unspoken words with their bodies.
The snow outside the window gradually stopped. Street lamps on campus made the accumulated snow gleam. And in this small rented room, two people entrusted their bodies and hearts into each other's hands.
Some secrets, once begun, never end. And they all knew, starting from that examination bed in the campus infirmary, the story had just written its first page.
When winter fully arrived, a thin layer of ice formed on the lake in the campus. Long Yu and Wang Xuan’s relationship also changed from the initial secret probing to the most natural part of each other’s lives.
Three weeks after Wang Xuan formally proposed the breakup, she slowly moved some daily necessities into Long Yu's off-campus rental. Not everything, just change of clothes, a spare set of toiletries, and the lubricant and condoms she commonly used. Long Yu didn't ask too much, only when she first placed the key in his palm, he pinned her against the wall in the entryway and entered her from behind.
That time, they didn't speak at all. Wang Xuan's hands were braced against the door, her waist dipped low, trembling slightly each time she was pushed to the deepest point. Long Yu's palm rested on her lower abdomen, feeling his own shape inside her. When he ejaculated, he didn't withdraw; holding her in the connected position, he carried her to the sofa and continued. Wang Xuan sat on him, leaning back against his chest, moving slowly up and down on her own. The snowlight from outside the window shone in, casting the outlines of the two figures faintly.
“From now on, you don’t need to go to the health center on Fridays anymore.” she gasped, “Just come back.”
Long Yu kissed the nape of her neck and responded with a sound.
The days that followed became regular, yet not dull.
During the day, they each had their own classes. Long Yu was doing rotations at the affiliated hospital, often on night shifts; Wang Xuan was busy with her own research project and surveys assigned by her advisor. But whenever both had free time, they would return to that small room. Sometimes after dinner, sometimes late at night. The moment the door opened, clothes would start coming off.
Wang Xuan likes it from behind. This hasn't changed since the initial examination in the clinic. She would suddenly hug Long Yu from behind while he was halfway through writing a medical record, her hand reaching into his pants to free his already semi-hard member. Then she would turn around herself, hands on the desk, presenting her back entrance to him.
“I want here today.”
Long Yu usually did not refuse. He would first use his fingers for dilation, apply ample lubricant, and then enter slowly. Wang Xuan's rear passage had become fully accustomed to his size, making the entry smooth and tight. She would gently sway her hips with his movements, occasionally looking back at him with a gaze full of satisfaction and a hint of mischief.
“Deeper... push to that spot.”
Long Yu would comply. Each thrust was heavy and slow, making her clearly feel the sensation of being filled. When she climaxed, her inner walls would contract violently, gripping him even deeper. He often held back until she had climaxed twice before releasing inside. Wang Xuan would clench tight, trying to keep as much of the semen in as possible, then lazily sprawl on the desk, letting him clean her up.
There were also gentle times.
Once, after finishing a 24-hour shift, Long Yu returned home at 2 a.m. Wang Xuan was still awake, wrapped in his hoodie, reading in bed. Seeing him enter, she put the book down, walked over, and helped him unbutton his shirt.
“Tired?”
“That’s good.”
She didn't say anything else, just led him to take a shower. Under the hot water, she knelt down and took him into her mouth. Her movements were light, very careful, her tongue circling the coronal sulcus, occasionally deep-throating to the very base. Long Yu's fingers threaded through her hair, not forcing her, just gently thrusting his hips in rhythm with her. When he came, she didn't pull away, swallowing it all, then looked up at him, the corner of her mouth still carrying a trace of white.
“You can sleep now.”
That night, they just fell asleep in each other's arms. Long Yu's palm rested on her smooth back, listening to her steady breathing, and he suddenly felt that this was more comforting than any intense sexual encounter.
When spring came, the cherry blossoms on campus bloomed.
The two began occasionally meeting during the day. It was not deliberate avoidance, just that they had not yet made things public. The library, the cafeteria, the bench by the lake, all became places where they could stay for a while. Once under the cherry blossom tree, Wang Xuan suddenly stood on tiptoe and kissed him. The kiss was very brief, yet enough to make the classmates passing by nearby look over.
Long Yu held her hand and did not let go.
“Do you want to make it official?” he asked.
Wang Xuan looked at him and smiled: "Are you confirming a romantic relationship with me, Dr. Long?"
“Yes.”
“Then I agree.”
From that day on, they stopped hiding it. Wang Xuan would openly go to the hospital to have dinner with him, and Long Yu would also show up at her project presentation, sitting in the last row and listening quietly to the end. At first their friends were surprised, but later they got used to it. Some teased them for moving too fast, and Wang Xuan simply smiled, leaning on Long Yu’s shoulder without explaining.
Physical intimacy never diminished.
The first weekend after officially getting together, they hardly left the house. On Friday night, as soon as Wang Xuan entered, Long Yu picked her up and took her straight to bed. This time, they were extremely patient from the foreplay. Long Yu kissed down from her collarbone, his tongue circling her nipples, his fingers gently pressing at her already moist entrance, yet he delayed entering. Driven to desperation by his teasing, Wang Xuan actively lifted her hips to meet his fingers.
“Stop messing around... come in.”
But Long Yu first had her turn around, using his tongue from behind to lick her back hole. Wang Xuan gasped in surprise, her body instantly tensing. His tongue tip probed skillfully, mimicking thrusting motions while his fingers rubbed her clitoris. The dual stimulation quickly brought her to climax once, her fluids trickling down her thighs.
While she was still trembling, Long Yu switched to his own member, slowly and firmly entering her back hole. After burying himself completely, he paused, lowering his head to kiss her spine.
“Are you okay?”
“Mm……so full.”
He began to move. At first it was very slow, each time almost pulling all the way out before pushing in again to the hilt. Wang Xuan's moans gradually loosened, her hands gripping the bedsheets tightly, her waist lifting back on its own. Long Yu sped up, and the slapping sounds were clearly audible in the room. He reached to the front, inserting two fingers into her vagina, creating a pincer attack with the thrusting from her rear hole.
Wang Xuan cried as she climaxed.
“Too deep... front and back both... ah...”
Long Yu did not stop. Maintaining this rhythm, he brought her to a second climax before releasing inside her. As the semen filled her, Wang Xuan went completely limp on the bed, only her rear passage unconsciously contracting, drawing the warm fluid deeper inside.
Afterward, they lay together, and a few cherry blossom petals were blown in through the window by the wind, landing on the windowsill.
Wang Xuan turned sideways, her fingers tracing his brow bone.
“Next year you'll be graduating.”
“Mm. It’s already settled at a top-tier hospital in the city, continuing residency training.”
“Then what about me? I still have two more years of doctoral study.”
Long Yu held her hand and placed it on his own chest.
"I'm right here. You're at school, I'm in the hospital. Come back on weekends, or you can come to my dorm. Either way is fine."
Wang Xuan looked at him for a long time, then leaned down and kissed him.
By the end of the kissing, both of them were aroused again. This time Wang Xuan took the initiative to straddle him and sat down all the way. She swayed her waist back and forth, her nipples bobbing in front of his eyes. Long Yu raised his hand to knead them, his fingertips brushing over the sensitive tips as he watched the expression on her face wrinkle slightly from pleasure.
“Like this?”
“Like…” she gasped, “I like you looking at me. And I also like you going all the way in.”
They changed into several positions. Sometimes she was on top moving herself, sometimes he embraced her from behind and did it, and sometimes she lay at the edge of the bed with her legs slung over his shoulders. Each entry was deep, and each withdrawal brought out a sticky wet sound. Wang Xuan's orgasms came dense and fierce, and by the end she was almost crying as she begged him.
“Shoot for me... all of it... I want it.”
During his final thrusts, Long Yu pressed her legs wide open, pushing deep with each stroke. At the moment of climax, he lowered his head to kiss her, muffling all their gasps between their entwined lips and tongues.
That night, they went at it until the early hours of the morning. By the end, Wang Xuan had no strength left to move, just lazily letting him clean her up. Long Yu carefully wiped between her legs and her back hole with a warm towel, then held her in his arms.
“Sleep.”
Wang Xuan hummed in agreement and quickly fell asleep. Long Yu was still awake. He looked at the ceiling, thinking about the cautious 'young married woman' from the initial chat room to the woman now lying beside him, breathing steadily. In between were one clinic examination, countless Friday nights, one breakup, and one formal confirmation.
And all of this originated from that examination bed.
Time continued to move forward.
Before summer vacation arrived, Wang Xuan's supervisor arranged for her to go to another city for two months of field research. The night before she left, the two of them barely slept in the rental apartment. Wang Xuan wrapped her legs around his waist, pulling him deeper again and again.
“For these two months... don’t look for anyone else.”
"No."
“When you come back, I want you to come straight in. Don’t make foreplay too long.”
Long Yu smiled, lowered his head, and nibbled her earlobe: 'Understood.'
When he ejaculated inside her for the last time, Wang Xuan held him tightly and buried her face in the crook of his neck. The warmth of the semen made her tremble slightly, but she did not let go.
The next morning, Long Yu accompanied her to the station. When parting, Wang Xuan stood on tiptoe and gave him a kiss, very light.
“Wait for me to come back.”
“Waiting for you.”
After the train pulled away, Long Yu stood on the platform for a long time. The phone in his pocket buzzed; it was a message from Wang Xuan:
“I’ll tell you when we get there. Miss you.”
He replied with one word: “Okay.”
Then turned and left.
During the two months of summer vacation, the two talked on the phone every day. Sometimes it was simple check-ins, sometimes late-night video calls with heavy breathing. Wang Xuan would take off her clothes one by one in front of the camera, pose as he requested, and use her fingers to mimic the motion of him entering. Long Yu would also hold himself on the other end, releasing to the sound of her voice.
“The first thing when you get back is to have you.” Wang Xuan once said in a hoarse voice.
“Good.”
At the end of August, Wang Xuan came back.
Long Yu went to the station to pick her up. The moment they met, they almost immediately kissed. Luggage was casually tossed by the door of the rental room, clothes discarded all the way from the entrance to the bedside. As she had said, Wang Xuan required almost no foreplay; she got on all fours herself, presenting her back hole to him.
“Come in directly.”
Long Yu applied lubricant but still used his fingers first to confirm she was sufficiently wet before slowly and firmly entering. The moment he was fully inside, both let out satisfied sighs.
This time, they did it fiercely and urgently. The longing from two months of separation was completely unleashed. Long Yu thrust to the deepest point every time, and Wang Xuan met him forcefully with each push backward. The sounds of slapping, wetness, and panting mixed together, filling the entire room.
Wang Xuan cried out when she climaxed. Not from pain, but from the grievance and satisfaction of being too full, too deep, and not having been filled like this for too long. Long Yu leaned down to kiss her tears, but his lower body did not stop.
"I'm here."
“I know... continue...”
When he finally ejaculated inside, Wang Xuan had already climaxed for the third time. The inner walls were still contracting nonstop, swallowing those warm fluids deeper inside. The two of them remained in that connected position until their breathing had completely calmed.
Afterward, Wang Xuan lay in his arms, her fingers unconsciously drawing circles.
"After school starts, I'll have to do my thesis proposal."
“I know.”
“Will you come listen?”
“Yes.”
She raised her head, looked into his eyes, and suddenly smiled.
“That examination bed seems like it was a long time ago.”
Long Yu tucked her hair behind her ear and answered seriously:
“But the story has only just reached the middle.”
The cicada chirps outside the window began to grow dense again. Summer had not completely passed, yet their lives had already become thoroughly entangled.
From that first sleepless night, to the first checkup in the clinic, to officially being together, to separation and reunion—every step was taken cautiously, yet there was no turning back.
Long Yu lowered his head and kissed her.
This time, there was no lust, only confirmation.
Wang Xuan kissed him back.
In this tiny rental room, in the new semester soon to come, they handed their bodies and hearts to each other, as if turning all the tested desires into a stronger, hotter wine belonging only to the two of them. And the story still continues.
