Once again it was the annual end-of-year banquet.

The company where my younger brother works is not exactly big, but not small either, with about seventy to eighty people, considered a medium-sized foreign enterprise. The higher-ups always like to instill in us the concept of a 'small but mighty' combat team, so the year-end party is naturally unavoidable. Personally, I don't really like this kind of socializing, but I still have to show up. Being unmarried, I brought my girlfriend Jiaqi along to attend.

I was wearing a formal suit and tie, sitting with colleagues from the same department at two tables near the corner. Jiaqi today wore a white sleeveless tight-fitting dress with a deep V-neck cut paired with a silver necklace, the hem about thirty centimeters above the thighs, layered with black stockings and high heels. Her hair was up, giving her a sexy yet intellectual vibe typical of a graduate student. Her fair skin and good figure were particularly striking under the lights.

Many male colleagues stared wide-eyed at Jiaqi, who was still a student. The deep V-neck revealing a hint of cleavage made many feel intoxicated even before drinking. Throughout the meal, people kept finding excuses to get closer by offering food or toasting, though most still cared about face and didn't dare go too far.

The only exception was Manager Wang from the neighboring department.

His real name was Wang Raoshu, and everyone privately called him “Mouse.” He was a bit plump, wore two small moustaches, and his eyes always carried a sly, shrewd look. He was quite capable at his work and knew how to curry favor with those above him, so he was doing fairly well. His popularity was average, though; including me, many people did not really like him.

Today he just happened to be seated next to Jiaqi. After several rounds of drinking, Jiaqi was urged by everyone to drink a few glasses of red wine; her fair skin gradually took on a rosy flush, and her slightly tipsy look made her even more charming.

While I was pulled by my tablemate to play drinking games with other departments, Mouse started chatting up Jiaqi.

“Classmate Lin, let me toast you. Still studying, huh? How long have you been dating Ajie?”

Jiaqi replied politely a few times. The mouse introduced himself as “Brother Wang” and boasted about how he had looked after me. Jiaqi, mindful of the situation, could only respond with polite small talk. The mouse took the opportunity to keep urging her to drink, and Jiaqi gradually grew somewhat unable to hold her liquor, so she excused herself and said she would not drink any more for now.

Rat looked at the slightly drunk Jiaqi, her ample breasts rising and falling with her breath, her pink lips particularly tempting under the light. His gaze grew increasingly blatant. He picked up a piece of cream cake and brought it to Jiaqi's mouth. Jiaqi was embarrassed to refuse. As soon as she opened her mouth, he also stuffed his finger in, saying, "Lick the cream clean."

Jiaqi sucked on his finger, using her tongue to clean off the cream. Mouse’s other hand quietly stroked her thigh wrapped in stockings, and he whispered some explicit words, even directly suggesting he would take her home or go to a hotel.

Jiaqi broke free of his fingers and refused, her face red. But Mouse took advantage of her momentary inattention and quickly slipped his fingers between her legs, pressing through the thong onto the already somewhat wet spot. Jiaqi’s body trembled, almost crying out. The alcohol, combined with the other party’s skillful technique, left her briefly dazed.

Just as she saw me toasting with the executives at the other end of the restaurant, she suddenly snapped back to reality, forcefully pushed the rat away, and sternly refused.

Rat wasn't annoyed either. He deliberately knocked over her wine glass, spilling red wine on her white skirt. He 'apologetically' suggested she go to the restroom to deal with it, otherwise the stain would be hard to wash out. Jiaqi glared at him angrily but still stood up and walked towards the restroom. Rat followed with a grin.

The basement women’s restroom was empty.

Rat pulled Jiaqi into his arms and kissed her forcefully. His tongue aggressively probed into her mouth, entangling with hers, while his hands were also busy—one hand slipped under her skirt hem, continuously stimulating the already moist spot through her stockings and thong; the other roamed over her body. Jiaqi was kissed until her breathing became ragged, and her body went limp.

Rat whispered in her ear that he had already added something to the red wine earlier. If she didn't thoroughly vent tonight, she wouldn't be able to sleep at all. Jiaqi was both shocked and angry, but the continuous caresses made her legs weak. Rat made her lean over the sink, facing the mirror as she took off her dress. Blushing, under the persistent teasing of his fingers, Jiaqi removed her clothes piece by piece, revealing a black bra, garter belt, and thong.

When she completely removed her dress, the mouse quickened his finger movements. Jiaqi finally couldn't hold back, her body trembling violently as she reached climax, going limp and leaning against his chest.

Rat told her to send me a message first, saying her clothes got dirty and she was going home early. Jiaqi nodded weakly. Then he took her away, heading straight for a nearby motel.

In the hotel room, Jiaqi lay on the bed, facing the floor-to-ceiling mirror. The man entered her from behind, his movements heavy and deep. The sound of flesh colliding echoed in the room. Jiaqi was thrust forward repeatedly, her beautiful hair disheveled, continuous moans escaping her lips. She was pushed to climax again and again, and later even actively asked him to come inside her.

After it ended, the two embraced, catching their breath. The rat, still unsatisfied, carried her into the bathtub. Using erotic handcuffs to secure her hands, he 'bathed' her while continuously caressing her chest and between her legs. He took out his phone, showing photos taken along the way—from undressing to various positions, to the fluids afterward. Jiaqi felt both embarrassed and annoyed but could only urge him never to let me know.

Rat pushed his luck further, proposing to give her a pair of nipple rings. Jiaqi initially refused, afraid of the pain. Rat promised there would be anesthesia, good technique, and said many models had them. In the end, Jiaqi bit her lip and compromised.

The piercing master arrived quickly. After anesthesia, a medical-grade steel nipple ring was pierced through, adorned with a jade-inlaid pendant. Jiaqi stood in front of the mirror, looking at the new decoration on her chest, feeling both unfamiliar and a strange sense of sexiness. The master reminded her not to let water directly hit it this month and not to wear a bra. Mouse excitedly took a few more photos, then pressed her back onto the bed, continuing to demand.

……

Late one night during the trip, I returned to the hotel nearly at dawn. The tour leader had us drink a bit more, so we came back later than the other group members. Pushing the door open, I saw Jiaqi asleep, with a metal collar around her neck and a special pair of panties on her lower body that couldn't be taken off, also with a lock.

She stammered, saying it was a souvenir bought while I was away, and the key would be mailed after returning to the country. I was half-convinced, half-doubtful, but didn't press further. Because she had said she wasn't feeling well the past couple of days, I had been pent up for days. Seeing her offer to help me with her mouth, I naturally didn't refuse.

Jiaqi knelt between my legs, unexpectedly skilled. Just as I was about to reach the peak, the doorbell rang. Team leader A Biao and Yang Dong were outside calling for a team-building activity, and they also mentioned “yesterday’s recording.” Jiaqi’s expression changed, and she immediately agreed to go participate.

When we got to the poolside, the five-member group led by Director Yang and a local girl named Judy were already having fun. Director Yang later told me privately that the collar and that special pair of pants were bought by him to “give” to me, and the key was in his hands. He proposed playing a thrilling game: if I won, both the key and the VIP card would be mine; if I lost, he only required Jiaqi to agree to one thing for him.

By this point, Jiaqi and I could only bite the bullet and agree.

After the game began, the intensity escalated rapidly. Chairman Yang and his group clearly had premeditated plans, with various punishments and rewards revolving around physical contact. Jiaqi, restricted by the collar and the pants that couldn't be removed, gradually got drawn into more extreme activities. Watching from the side, I felt complex emotions, yet a twisted excitement prevented me from truly intervening.

That night, the lights by the pool, the sound of water, and the sounds of entangled bodies mixed together. Jiaqi was pushed to the edge of climax again and again, the pendant on her nipple ring swaying gently with the movements, emitting faint sounds. Chairman Yang and the others took turns approaching, playing with her body, which was already sensitive to the extreme, in various ways. And I, in the end, did not stand by idly either.

By the time everything ended, the sky had already brightened. The key was handed to me, but some things could never return to how they were before.

Jiaqi leaned against my shoulder and said softly, “After we go back... will you still want me?”

I didn't answer immediately, just tightened my arms.

Some doors, once opened, can never be closed again. And this secret relationship that started on the year-end party night is far from over.

After returning from Thailand, Jiaqi and I appeared to resume our прежvious lives on the surface. She continued graduate school, and I went to work as usual. But some things were already different.

The nipple rings on her chest were still in the adjustment period. The piercer said to try not to get them wet this month and not to wear a bra. So during class, she could only wear loose clothes, trying to cover the provocative outline as much as possible. But summer was hot, and thin shirts would still vaguely reveal the shape of those two points lifted by the metal rings. Once, when she stood up to answer a question in class, a male classmate in her group noticeably paused his gaze. She pretended not to see, but the roots of her ears quietly turned red.

What's even more troublesome is that special pair of panties. Although the key is back in my hands, Jiaqi said she's still not used to it and occasionally asks to lock it for a few days herself. She said the feeling of being completely restricted makes her inexplicably tense and excited in daily life. I didn't understand at first until one time she locked it in front of me and was soaking wet all night—then I vaguely grasped that psychological stimulation.

On the company side, the rat still had not restrained itself.

After the year-end party, he became even bolder. Sometimes he would find excuses to send me away, seeking Jiaqi alone to 'discuss work.' Once, returning to my desk after a meeting, I saw him standing beside Jiaqi, his hand seemingly casually resting on the back of her chair, his thumb subtly stroking the nape of her neck. Jiaqi's body stiffened slightly, but she didn't make a scene on the spot. After the rat left, she let out a soft sigh and whispered to me, 'He just said beside my ear that he wants to see the nipple ring again tonight.'

I was furious, but I didn't know how to vent. After all, I was fully aware of what happened that night, and even somewhat acquiesced to it later.

What truly caused the relationship to completely deteriorate was a weekend one month later.

That day, I worked overtime, and Jiaqi said she was going to the school library to look up materials. After ten at night, I returned home and found she wasn't there. Her phone was unreachable. Just as I was about to go out to look for her, the door lock clicked.

When Jiaqi came in, her hair was a little messy and her lipstick had faded. She saw me, froze for a moment, then gently closed the door.

“Where did you go?” I asked.

She didn't answer immediately. Instead, she walked over and sat on the sofa, looking down at her fingers. After a long while, she said, '... Manager Wang said there was an urgent document to deliver and asked me to help run the errand. Later... I went to his place.'

My heart sank. 'And then?'

Jiaqi raised her head, her eyes a little red, yet she was very calm. “He wanted to see the nipple ring. He also wanted... to do it again. I said no. But he took out his phone and showed me the photos he took at the year-end banquet that day. He said if I didn’t behave, he’d send them to the company group chat.”

The air seemed to freeze.

“You agreed?” My voice was a little hoarse.

She nodded, very softly. 'I was scared. I was scared you'd get implicated, and scared those photos might really get leaked. So... I let him look. And I let him touch me. Later, he wasn't satisfied, so he pinned me down on the sofa. I didn't resist. After he finished, he drove me back and said he wanted to meet again next week.'

I walked up to her and crouched down to look at her. Jiaqi's eyes were red, but she tried hard not to let the tears fall.

“I’m sorry.” she said.

I didn't speak, just reached out and pulled her into my arms. Her body stiffened for a moment, then softened as she buried her face in my shoulder. After a long time, she asked in a muffled voice: 'Do you still want me?'

“Yes.” I said.

From that day on, this relationship became a secret among three people.

Rat knew very well how to gauge the limits. He wouldn't pester every day, but he always appeared at critical moments. Sometimes on a weekend afternoon, sometimes on a night when I was away on business. Jiaqi would receive his message and then silently go out. When she returned, she often carried his scent or had residual wetness between her legs. She rarely took the initiative to mention the process, only washing very carefully afterwards and then quietly leaning against me.

Once she came back very late. When she entered, she walked a bit unnaturally. I asked her what was wrong, and after hesitating for a long time, she blushed and said, 'He... used the back today.'

My mind buzzed.

With her head down, Jiaqi’s voice was so soft it was almost inaudible. “He said he’d already gotten bored of doing it up front and wanted to change places. I originally wanted to refuse, but he took out that photo of the nipple ring just after it was pierced and threatened to send it to my advisor’s email. I... just agreed. At first it hurt a lot; later I don’t know if my body just adapted, but I actually started to feel something. When he came inside me, I even came once. On the way back I was scared all the way, and I kept thinking.”

We didn't have sex that night. I just held her, my palm gently covering her slightly warm lower back. She buried her face in my chest and fell asleep after a long while.

Over time, a certain twisted balance gradually formed.

I began checking her body before she went out—whether her nipple rings were clean, if her panties were locked properly, if she had applied the perfume he liked. Sometimes I would even personally help her prepare, like applying lubricant between her legs, or using a toy to make her climax once first, letting her go to see him with the afterglow. Jiaqi was initially very resistant to this feeling of 'being prepared,' but gradually became accustomed to it, even主动分开腿 during inspections to let me see仔细.

She said the feeling of being used by two people was strange. On one side was me, her official boyfriend; on the other was that man who could blackmail her with photos at any time. Two completely different kinds of touch, rhythms, and scents made her feel intense shame when switching between them, and this shame would transform into even stronger excitement.

Once Laoshi was on a business trip for two weeks. During those two weeks, Jiaqi became especially clingy. We did it almost every day, sometimes twice a day. She would actively ask me to take her from behind, or have me cum on her nipple ring, then lick it clean bit by bit. She said only this way could she temporarily forget the other person's existence.

But as soon as the mouse came back, the text message followed.

“Tonight at nine, same old place. Clean the back thoroughly, and change the nipple ring to the pair of long pendants I gave you last time.”

Jiaqi looked at her phone and stayed silent for a long time. Then she went into the bathroom and began to wash herself carefully. I stood at the door watching her bend over, watching water droplets run down her back, watching her use her own fingers to clean herself. At that moment I was so hard it hurt, but I did not step forward.

When she came out, she was wearing only a loose jacket. Nothing underneath; the pendant on the nipple ring swayed lightly as she walked, leaving faint red marks at her collarbone. She walked up to me and took the initiative to kiss me once.

“Wait for me to come back.” she said.

After the door closed, I sat alone on the sofa, listening to the steady ticking of the clock on the wall. My mind was filled with what she might be experiencing right now—being pressed against the floor-to-ceiling window by him, being entered from behind by him, being forced to look up by him pulling on the pendant of her nipple ring... These images were terrifyingly clear and terrifyingly stimulating.

She only came back at two in the morning.

Her steps were somewhat unsteady as she entered. Her coat was open, and she wore nothing underneath. The charms on her nipple rings had been replaced with another pair—longer, with tiny bells hanging from the ends. With each step, they emitted an extremely faint sound. Fresh finger marks were visible on the inside of her thighs, and there were bruises on her lower back from being grabbed.

Seeing I was still awake, she paused for a moment, then slowly walked over and straddled my lap.

“He was especially rough today.” Her voice was a little hoarse. “After using my back twice, he even made me dig his semen out myself and show it to him. The last time, he came in my mouth, and made me hold it in on the way home — I could only swallow it at the door.”

While saying these things, she looked at me without flinching. I reached out and touched her nipple ring, gently pulling on the charm. The bell tinkled once. Her body trembled, and her breathing immediately became ragged.

“Want more?” I asked.

She nodded.

That night, we did it fiercely and for a long time. I pinned her on the sofa, the floor, the bathroom wall, using every method to leave marks on her that belonged to me. She cooperated unusually actively, holding me tightly when she climaxed, as if trying to embed herself into my body. By the end, both of us were exhausted, collapsing on the bed to gasp for breath.

She turned her head slightly, her voice very soft: “Sometimes I feel like I’m broken.”

“What’s broken?”

“Even though I’m clearly being threatened, I still look forward to his messages. Even though I’m afraid, my body reacts first. When I return to your side, I even feel excited because I betrayed you.” She paused. “Tell me, have I already ceased to be the person I was?”

I didn't answer immediately. Just pulled her into my arms, my palm covering her slightly rising and falling abdomen.

“Then show me how bad you can be.” I said.

From then on, this relationship became more openly shared among the three of us. Knowing that I was aware, Mouse became even more reckless. Sometimes he would even hint at things in a way only the three of us could understand at the company—for example, “casually” bringing up a detail from last night in the tea room, or turning his phone screen toward me during a meeting, showing a close-up of Jiaqi's nipple rings.

I learned to endure, and I also learned to derive another kind of pleasure from that endurance.

Jiaqi, meanwhile, kept swinging between two extremes. Sometimes after being used by the mouse, she would deliberately go home without cleaning up, so I could taste with my own mouth the flavor left behind by another man. At other times she would cry and beg me, saying she wanted to end all this, wanted to take out the nipple ring, throw away the key, and become mine alone again.

But whenever Old Mouse’s message sounded again, she would still go out.

One night, she came back unusually early. After entering, she walked straight up to me and handed over her phone. On the screen was a video sent by Lao Shu—she was tied to a chair in a hotel, her nipple rings connected by thin chains, her lower body completely exposed, her eyes blindfolded with a cloth strip. In the video, she was being tormented by some kind of vibrating toy, her body twisting constantly, yet unable to make a sound (a ball gag was in her mouth).

“He said he wants to livestream it for me tomorrow.” Jiaqi’s voice was very calm. “He asked if I agreed. He also asked if you agreed.”

I looked at her in the video, watching those familiar physical reactions, and suddenly asked, 'Do you want it yourself?'

She was silent for a long time before nodding.

"Yes. But more than that, I want you beside me watching.",

So the next day, I really went.

The hotel room was large. Mouse saw me appear and just smiled, without any extra words. Jiaqi was already prepared—eyes blindfolded, hands tied behind her back, with tonight's new pendant hanging from her nipple rings. Hearing my footsteps, her body noticeably tensed, but she didn't make a sound.

Rat did it very slowly. He made me sit on the sofa directly opposite, while he stood behind Jiaqi, using his hands, props, and body to gradually push her towards climax. Jiaqi went from initially suppressed gasps to later completely letting go with her voice. She called my name, and she called his name, unable to tell who she was begging for mercy from or who she was demanding from.

When the rat finally entered her, he deliberately turned sideways so I could clearly see the point of union. Jiaqi's legs were spread wide apart, each impact producing a sticky, wet sound. Her toes were pointed, her lower abdomen constantly contracting. I was painfully hard, yet just sat there watching.

At the end, the rat ejaculated on her lower belly, then removed the blindfold. Jia Qi squinted to adjust to the light, and when she saw me, tears suddenly fell.

She didn't speak, just looked at me.

I walked over, crouched down, used my hand to wipe the white fluid from her lower abdomen, then brought my fingers to her mouth. She hesitated for a moment but still opened her mouth and licked clean what belonged to another man.

Rat smoked a cigarette nearby, speaking casually: "You two are really interesting."

When she came out of the hotel, the night breeze was a little cool. Jiaqi was walking beside me, still a bit unsteady on her feet. Suddenly she reached out and took my hand, gripping it tightly.

“Go home.” she said.

I nodded.

In the car, she kept leaning on my shoulder. At a red light, she suddenly spoke: 'Next month, I have to present my thesis proposal. My advisor is very strict, so I might be busy for a while.'

“Mm.”

“During that time... can you not let him come looking for me again for now?”

I turned my head to look at her. Her eyes were looking ahead, her expression calm, yet carrying a hint of pleading.

"Okay." I said.

She relaxed and buried her face back into my shoulder.

But I know this is only a temporary ceasefire. The nipple rings are still there, the photos are still there, and the feeling her body has already remembered is still there too. As long as the mouse is willing, it can press the start button again at any time.

And both Jiaqi and I seem to have no way to truly turn it off anymore.

After returning home, we showered for a long time. The hot water washed away the smell on our bodies, but it could not wash away the memories left beneath the skin. When we got into bed, Jiaqi took the initiative to straddle me and swallowed me inside herself. She moved very slowly, very deeply, her eyes fixed on me the whole time.

“Shoot inside.” She said, “Tonight, it’s only allowed to be yours.”

I held her waist tightly, thrusting upward. She bit her lip, enduring it, occasionally letting out soft moans. When it ended, she lay on my chest, listening as our heartbeats gradually calmed.

Outside, dawn was about to break.

This secret relationship that started from the year-end party night, like a long shadow, has completely enveloped our lives. It brings shame, fear, pleasure, and also a kind of inseparable bond. We both know that a real end is far from sight.

And before that, we could only keep moving forward.

Even if every step is on a rope that could collapse at any moment.
