My wife has a very close colleague and friend named Xiao Jing, who is 30 years old this year. They used to work at the same unit. In 2006, Xiao Jing passed an exam and entered a government agency, becoming a section-level cadre. Although they no longer work at the same place, since they graduated from university together and started working together, living together for three years, they are iron sisters who talk about everything.

On the twentieth day of the twelfth lunar month, Xiao Jing called, saying she wanted to visit us as the Spring Festival was approaching. My wife was very happy and prepared a sumptuous meal with red wine. Lunch was very comfortable. Watching the two women talking together, I also felt quite content, listening on the side. Xiao Jing's husband works in Guangzhou; they've been married for eight years, living mostly apart with little time together. Due to heavy snow, he couldn't return home for the New Year this year. From the conversation, it was clear that Xiao Jing envied our kind of reunited life, and her words and demeanor revealed a faint sense of melancholy.

While Xiao Jing was in the bathroom, I said to my wife, 'You haven't seen each other for a long time. Let Xiao Jing stay overnight tonight so you can catch up on life.' Since my wife and I often watch adult videos and read novels together, we find wife-swapping stories fresh and exciting. When making love, we often talk about the hardships of living alone like Xiao Jing. I once joked to my wife that if Xiao Jing was willing, I could help her satisfy her sexual hunger. My wife is open-minded and said, 'As long as you have me in your heart, I don't object to you having sex with Xiao Jing. On one hand, it enhances sexual pleasure; on the other, it deepens our friendship with Xiao Jing. We're all good sisters. In ancient times, men had three wives and four concubines. Nowadays, as long as my husband treats me well emotionally and spiritually, I can understand him having sex with my sister one more time.'

Enough digression, let's get to the point.

After discussing with my wife, I begged her to ask Xiao Jing if she had any thoughts about staying for some intimate fun. I told my wife we could start by talking and testing the waters, otherwise it might hurt our friend's feelings. My wife said: 'Don't worry, we often discuss on the phone whose husband's dick is bigger, yours or Xiao Jing's! Married close female friends share a lot of private talk related to sex.'

After lunch, I was watching TV with the child, while my wife and Xiao Jing were on the computer reading novels and watching movies, chatting as they watched about feelings and needs in married life. Whenever they saw exciting or novel scenes, they would giggle, and occasionally I heard Xiao Jing ask: “Has your husband done that too?” My wife said: “Of course. As long as it feels good, we use every position and method. The most comfortable position is me on top, haha.” Xiao Jing said: “It’s so nice to have a husband by your side. You can eat dick whenever you want, unlike me — sometimes I’m full, sometimes I’m starving. When I’m really craving it at night, I have to use my hand myself. Sigh, there’s really nothing I can do about it.”

My wife said, 'Hey, Xiao Jing, you know what? My husband said if you're willing, he can let you suck his dick. He really likes your big breasts. If you're willing, how about letting my husband sleep with you tonight? We're good sisters. As long as my husband doesn't fool around outside, I support him having sex with my sister.'

“Really? You won’t be jealous, will you?” the wife said: “How could I? We’re good sisters, after all. There’s one condition though: don’t snatch him away from me because you like making love with my husband, or I’ll be the one suffering.” Xiao Jing said: “I definitely won’t, and I’m very grateful to you, my good sister.”

After getting Xiao Jing's consent, my wife came over, hugged me, and said, 'Hubby, go ahead and get intimate and familiar with Xiao Jing first. Don't wait until we actually do it and feel awkward.' Seeing my wife so understanding, I hugged and kissed her tightly, then went to the study computer to read novels with Xiao Jing.

Xiao Jing is 165 cm tall, with a瓜子脸 (oval face), a small nose bridge, and full lips. Well-maintained, her skin is delicate, dewy, and very fair. With a slender willow-like waist and rounded buttocks, she exudes the sensuality and beauty of a mature young woman. Especially her large breasts—even through her sweater, you could see her nipples pushing the fabric up high. She sat on my lap, and I hugged her from behind, my hand slipping into her sweater, fingers gently kneading and flicking her nipples. 'Xiao Jing, your breasts are so big, I can't even hold them all,' I said. 'Jun-ge, Xiao Wen and I are good sisters. Thank you both for being so considerate of me. Tonight, I'll definitely serve you well together with her.' As she spoke, Xiao Jing's lips came close, gently kissing mine. I also kissed her passionately while caressing her. The rich fragrance of a young woman flowed into my mouth, stimulating my brain. My heart raced wildly, and my blood slowly began to boil.

My hand slowly caressed Xiao Jing's body, starting from her neck downward, passing over her chest, and lingering on her breasts. The other hand reached from behind into her waistband, fondling Xiao Jing's full, round buttocks... Gradually, Xiao Jing seemed to enter a wonderful dream, softly moaning, her body writhing and entwining under my caresses and kisses, making 'mm' sounds from her mouth. Seeing Xiao Jing's seductive appearance, a feeling of cherishing her arose. I picked up Xiao Jing, kissing her as I walked into the bathroom.

“Bro, let me help you take off your clothes.”

“Mm, okay, Xiao Jing.”

Xiao Jing began gently and slowly taking off my clothes. When she saw my well-developed chest muscles, thick black pubic hair, rounded buttocks, and thick, erect penis, she couldn't help but gasp in surprise and delight, whispering in my ear, 'Jun-ge, you're so sexy, no wonder Xiao Wen often praises you on the phone. I like men like you.' After saying this, she pressed tightly against me and hugged me. I also slowly undressed Xiao Jing. Her smooth, fair skin and full, perky large breasts jumped out like a pair of jade rabbits. At the root of her rounded thighs, thick, dark pubic hair gleamed. Due to the earlier caresses and kisses, both large pink labia were covered in pale white, sticky love juices. I joked, 'Xiao Jing, look, you're drooling.' Xiao Jing said coyly, 'Brother, it's all for you. Let's wash down there properly first. Later, I want to taste your dick.'

“Mm, okay, as long as Xiao Jing can eat her fill and eat well, I’ll do a good job as this landowner, and your little sister Wen will be satisfied.”

“Bro, with such a great husband like you, Sister Wen is so happy!”

Standing under the showerhead, water rushing down, we held each other tightly, kissing and caressing, soon washing clean all over. Xiao Jing said, "Brother, I want you to enjoy this properly." As she spoke, she crouched down, her head lowering to my crotch, her small mouth gently taking my swollen, purple glans into her mouth, now swallowing and releasing, now tightly wrapping her lips around it, now licking, twirling, and sucking with her tongue. I slowly savored it while leaning down to use my hand to stroke and caress Xiao Jing's buttocks and vulva, occasionally inserting a middle finger into her already flooded vaginal opening, shallowly and quickly stimulating her vagina. Under my caressing stimulation, Xiao Jing, feeling pleasured, shook her head while vigorously sucking my thick penis and swayed her hips, enjoying my touch. After quite a while, she breathlessly released my penis from her mouth and said, "Brother, I can't take it anymore, I want your big cock to quickly thrust in and fuck my tender little pussy."

“Mm, okay, little sister.” After saying that, I embraced Xiao Jing face to face. She held my big dick with her small hand, and the glans rubbed quickly against her clitoris and labia; her fluids flowed onto my glans and penis. She, meanwhile, was so aroused she could die from bliss, moaning “mm mm mm” in her mouth and shouting, “Bro, hurry up and come in, my pussy is so itchy.”

“Sis, climb up onto the washstand, and I’ll fuck your tender pussy from behind, okay?”

"Good brother, I like it best this way. Don't forget to touch my breasts with your hand."

“Mm, okay.”

Xiao Jing lay on the bathroom counter, her plump, round buttocks presented before me like a kettle. Her slightly dark anus was closed like a chrysanthemum, dense black pubic hair covering her labia majora, her labia minora already parted, with much vaginal fluid flowing around her buttocks and anus. I raised my thick, large cock and gently, quickly rubbed it around her anus and vulva. Xiao Jing moaned and pleaded, 'Brother, fuck me quickly, my tight little pussy is so itchy, sister wants your big cock to fuck me hard.' I said, 'Okay, lift your buttocks higher so I can fuck you deeply.'

“Mm, bro, I’ll listen to you.”

After saying that, Xiao Jing buried her head even lower, raised her buttocks high, completely exposing her private parts before my eyes. My thick glans slowly inserted into her vaginal opening, all the way to her cervix, then stopped moving. I could feel the tender flesh inside her vagina tightening around my big cock, with a lot of fluid seeping out, soaking my entire penis wetly. Xiao Jing swayed her hips, moaning, enjoying the friction of my big cock inside her vagina. The inside of her vagina also tightened and loosened rhythmically, like a little mouth kissing my big cock. It felt so good I forgot myself, involuntarily starting to thrust deeply and rapidly. The 'squelch, squelch' sounds accompanied Xiao Jing's loud cries and moans echoing in the bathroom.

We did it for a long time. Xiao Jing said, 'Brother, I'm tired, let's change positions.'

I said, 'Xiao Jing, no rush. Tonight, when we're in bed, I'll let you properly suck my cock, okay?'

Xiao Jing said, 'Yeah, it's been a long time since I had sex. You fucking my tight pussy feels so good. Tonight, I want you to enjoy yourself.' I said, 'Sure, let Xiao Wen help you.'

“Mm, okay, good brother.” Saying that, Xiao Jing stood up and, while stroking my big dick, kissed my chest. It was so beautiful.

Just enjoying this tenderness, my wife called from outside: 'Are you two done? Time to come out for dinner.'

My wife's voice came from outside the bathroom door, carrying a hint of teasing and laughter.

Xiao Jing lifted her head, her face still flushed from earlier, gently pushed me, and said softly, 'Brother, go out first, don't keep Sister Wen waiting.'

I nodded, helped her put on her clothes one by one, and quickly dressed myself. We glanced at each other and couldn't help but laugh. Xiao Jing tidied her hair and whispered in my ear, "Tonight... we'll continue properly."

Opening the bathroom door, my wife was leaning against the doorframe, holding a plate of cut fruit, her eyes full of mischief.

“We’ve been chatting so long, the water must be cold by now?” She handed over the fruit, deliberately glancing at the two of us. “Your faces are all red like that—have you already had a round first?”

Xiao Jing's face turned even redder, but she didn't shy away. Instead, she actively linked arms with my wife. 'Sister Wen, thank you... really.'

My wife patted the back of her hand and smiled: 'Saying that makes it sound distant. Come on, let's eat. You need to be full to have the energy to serve our big contributor tonight.'

The dinner atmosphere was more relaxed than at noon. On the table were a few extra dishes specially prepared by my wife, and another bottle of red wine was opened. The child had already gone back to their room to do homework, leaving only the three adults in the living room.

Xiao Jing sat between my wife and me, occasionally serving me food, occasionally pouring wine for my wife. After several rounds of drinks, the conversation also grew livelier.

“Actually... at first I really hesitated.” Xiao Jing put down her chopsticks, her voice a little soft. “I was afraid I’d ruin your relationship, and I was also afraid I wouldn’t be able to control myself. But just now in the bathroom, Brother Jun was so gentle, and I suddenly felt... the feeling of being accepted by you both is really nice.”

My wife reached out and held her hand: 'We've discussed this many times. As long as everyone is happy and no one gets hurt, there's nothing to fear. You're my best sister, and I want you to feel good too.'

I sat to the side, quietly listening to the conversation between the two women, a strange sense of satisfaction welling up in my heart. Not just simple lust, but a feeling of being trusted, of being shared with.

After dinner, the child washed up and went to sleep. The lights in the living room were dimmed a little, leaving only one floor lamp on. My wife went to take a shower first, leaving me and Xiao Jing sitting on the sofa.

Xiao Jing leaned over, resting her head lightly on my shoulder, her voice very low. 'Brother, is Sister Wen really not jealous at all?'

I turned my head and kissed the top of her hair: 'She's much more generous than you think. And she said seeing you feel good excites her even more.'

Xiao Jing was silent for a few seconds, then suddenly lifted her head and actively kissed me. This kiss was deeper than the one in the bathroom, carrying the sweetness of red wine and her own tenderness. My hand slipped under her sweater again, my palm against her warm skin.

At that moment, the bathroom door opened.

My wife walked out wrapped in a towel, her hair still dripping. Seeing our posture, instead of getting angry, she smiled and walked over, sitting down next to Xiao Jing, turning her face towards herself.

“Let me have a taste too.”

The sight of two women kissing was right in front of me. Watching their soft lips intertwined and their tongues gently twining together, I was completely aroused. My wife, while kissing Xiao Jing, loosened her bath towel, revealing her fair and plump body, then took Xiao Jing’s hand and placed it on her chest.

“Tonight we’ll be together.” My wife said softly, “Serve him well, and enjoy yourself too.”

Xiao Jing nodded, her eyes completely moist.

The three of them walked into the bedroom together. The door gently closed behind them.

The bed was large enough to accommodate us. My wife first pressed Xiao Jing onto the bed, then straddled her waist, leaning down to continue kissing her while pulling my hand, having me embrace both of them from behind. My chest pressed against my wife's back, and my hands reached around to knead the breasts of both women—one familiar and belonging to me, the other new, soft, and full.

Xiao Jing moaned softly beneath, her hands unsure where to place, finally just gripping the bedsheet tightly. My wife lifted her head and smiled at her: 'Relax, no one is in a hurry to finish tonight.'

The time that followed became long and soft.

I first had Xiao Jing lie down, knelt between her legs myself, lowered my head to kiss her abdomen, inner thighs, and finally took her already moist labia into my mouth. Xiao Jing's waist immediately arched up, letting out a soft cry. My wife sat to the side, one hand stroking Xiao Jing's hair, the other holding my penis, slowly moving up and down.

“Bro... so comfortable...” Xiao Jing’s voice was already tinged with tears.

I looked up, switching to gently probing with my fingers while lifting my head to kiss her. My wife lowered her head, taking my glans into her mouth, skillfully licking with her tongue. Both their mouths and hands pleasured me simultaneously, the sensation so intense it was almost overwhelming.

After a while, my wife主动 moved aside, signaling me to enter Xiaojing.

I guided my penis, aiming at her slick entrance, and slowly pushed in. Xiao Jing's vagina was hot and tight, swallowing me inch by inch. She wrapped her arms around my neck, buried her face in the crook of my shoulder, and let out a long, satisfied sigh.

“All of it... got in...”

I started thrusting slowly, each time trying to reach the deepest point. My wife knelt beside us, lowering her head to kiss Xiao Jing's breasts, sometimes sucking on her nipples, sometimes gently biting. The two women's panting intertwined, and the mattress swayed gently with the motion.

After going at it for a while, Xiao Jing said she wanted to change positions. I got her to lie down properly and entered from behind. At this angle I got in deeper; her butt was raised high, and with each thrust there was a crisp sound of flesh slapping. My wife crawled under her, tilted her head up to kiss her, while using her hand to tease her clitoris.

Xiao Jing soon reached her first climax. Her body trembled violently, her vagina contracting in waves, squeezing me painfully. I resisted the urge to ejaculate, slowed down, and let her gradually calm down.

“It’s your turn.” Xiao Jing panted to his wife.

My wife lay down with a smile and spread her legs. I got off Xiao Jing and entered my own wife instead. The familiar enveloping sensation made me let out a low sigh. Xiao Jing knelt beside us, lowering her head to suck on my wife's nipple, with one hand reaching down to help stimulate her clitoris.

The three of them took turns exchanging positions and roles like that. Sometimes I would insert my fingers into two people at the same time; sometimes two women would service me together with their mouths and hands; sometimes they would hook their legs around each other’s thighs and rub against one another. Sweat, bodily fluids, and low moans mixed together, and the air was full of the smell of lust.

Finally, I had Xiao Jing sit on me while I lay on my back. She braced herself on my chest, moving up and down. My wife knelt beside my head, letting me lick her while feeling Xiao Jing's movements. Pleasure built up layer by layer until, at a certain moment, we all reached the peak simultaneously.

When I ejaculated inside Xiao Jing, she also reached climax, leaning forward and holding me tightly. My wife, under my tongue, trembled and came, her love juices flowing down my chin.

Afterward, the three of them lay side by side on the big bed, and no one hurried to clean up. The wife’s fingers gently combed through Xiao Jing’s hair, while Xiao Jing’s hand rested on my chest.

“Thank you.” Xiao Jing’s voice was very soft, but sincere.

My wife turned her head and kissed her forehead: 'If you ever want to come back, just say the word. Our door is always open for you.'

I pulled both women into my arms, feeling their warm body heat. Outside the window was the cold night of the twelfth lunar month, but the room was warm and quiet.

This night would continue.

But at least at this moment, all three of them felt a rare sense of satisfaction and peace.

Only the sound of even breathing remained in the room. The floor lamp was dimmed to its lowest, and the curtains were drawn tightly. Xiao Jing lay on my right side, one hand still lightly resting on my chest; my wife pressed against my left side, her legs entwined with my calf, her fingers tracing my collarbone intermittently.

After a long time, Xiao Jing suddenly spoke softly, 'Actually... when I came just now, many images flashed through my mind. When I was alone before, I always felt like something was missing. Only tonight did I realize that being trusted and shared with is more comforting than mere physical satisfaction.'

My wife softly 'mm'-ed and buried her face in my shoulder: 'That's why I'm willing. Seeing you comfortable makes me happier than being comfortable myself.'

I held both of them a little tighter, not saying anything. Some emotions don't need to be confirmed with words.

After a while, Xiaojing’s fingers began drawing circles on my chest, her movements getting slower and slower, yet more and more intentional. She raised her head, looked at me, and with a slightly hoarse aftertone in her voice said: “Brother... is it still okay?”

I lowered my head and kissed her forehead, then turned to kiss my wife. My wife understood immediately, sat up on her own, propped the pillow higher, leaned against the headboard, and patted her thigh: 'Come here, Jingjing. This time, I'll hold you.'

Xiao Jing crawled over, leaning back against my wife's chest. My wife wrapped her arms around her from behind, cupping her breasts with both hands, thumbs gently teasing her already somewhat swollen nipples. Xiao Jing nestled in her embrace, eyes half-closed, emitting soft nasal sounds.

I knelt before them, first lowered my head to kiss Xiao Jing's lower abdomen, then followed the midline all the way down. Her labia still carried the wetness and slight swelling from earlier. I gently parted them with my tongue tip, found that already sensitive clitoris, and slowly swirled around it.

Xiao Jing's waist immediately went soft, her hands gripping my wife's arms tightly. My wife whispered soothing words in her ear, while kneading her breasts and occasionally lowering her head to kiss her neck.

“Relax... let him lick properly...”

I added another finger, slowly probing inside, finding that spot on her inner wall, and gently pressing. Xiao Jing's breathing immediately became ragged, her legs unconsciously clenching and then relaxing. My wife's hand slid from her chest to her lower abdomen, holding her down to prevent her from writhing too much.

“Bro... a little deeper...” Xiao Jing’s voice was already tinged with tears.

I switched to two fingers, simultaneously speeding up the rhythm with my tongue. My wife reached a hand down to help spread her labia apart, allowing me to make more thorough contact. The breaths of the two women intertwined, the mattress gently rocking.

Xiao Jing quickly came again. Her whole body arched, leaning against my wife's embrace as she trembled violently, her vagina contracting in waves, tightly gripping my fingers. Love juices flowed down the back of my hand to my wrist. I didn't stop, continuing to gently stimulate until she completely softened, then slowly withdrew my fingers.

My wife lowered her head and kissed her sweaty forehead, smiling at her: 'Alright, now it's my turn.'

Xiao Jing panted and nodded, actively turning over to let my wife lie down. She imitated my earlier actions, kneeling between my wife's legs, first gently probing with her fingers, then lowering her head to take her in her mouth. Her movements were somewhat clumsy but exceptionally earnest. I hugged Xiao Jing from behind, one hand reaching around to fondle her breasts, the other holding my already re-hardened penis, slowly rubbing it between her buttocks.

My wife closed her eyes, one hand pressing Xiao Jing's head down, the other gripping the bedsheet, letting out suppressed moans. Xiao Jing occasionally lifted her head to breathe, her lips and chin wet, but her eyes were strikingly bright.

I couldn't wait any longer. Lifting Xiao Jing's waist a little, I aimed at her still wet and soft entrance and slowly re-entered. She let out a long sigh, her whole body leaning forward, burying her face between my wife's legs, but she didn't stop servicing with her tongue.

The three people are reconnected.

I thrust from behind, reaching the deepest point each time; Xiao Jing, while being entered by me, focused on pleasing my wife; my wife, meanwhile, sometimes looked down at us, sometimes reached out to stroke Xiao Jing's hair and back. The sound of flesh colliding and wet noises filled the room again, mixed with suppressed yet clear gasps.

This time neither of us was in a hurry to finish.

I tried several angles. Sometimes I had Xiao Jing sit up and move on her own, sometimes I had her lie on top of my wife while I entered from behind, simultaneously reaching a hand around to stimulate my wife in front. Xiao Jing's orgasms came faster and faster, each contraction gripping me so tightly it made my scalp tingle. My wife also climaxed twice in a row under the dual stimulation of her tongue and my fingers.

Finally, I turned Xiao Jing over, having her sit facing me on top of me. My wife knelt beside us, one hand on my shoulder, the other reaching down to help guide me inside. Xiao Jing braced her hands on my chest, moving up and down on her own, her pace getting faster and faster. I felt the urge to ejaculate rising again, so I reached out and held her waist, asking in a low voice:

“Is it okay?”

Xiao Jing nodded, holding me tighter. 'Inside... I want it.'

My last few thrusts were deep and heavy, all ejaculated inside her. She climaxed simultaneously, her whole body trembling as she lay on top of me. My wife then leaned down to kiss both our cheeks, one hand still gently stroking Xiaojing's back.

Afterward, the three of them lay side by side again. This time no one said anything; they only intertwined their fingers, their breathing gradually syncing.

At some point, a light snow began to fall outside the window. The room was warm and quiet.

Xiao Jing suddenly whispered, 'Tomorrow... can I stay one more day?'

My wife turned her head and nodded with a smile: 'Stay as long as you like. Anyway, the kids are going to a friend's house during the day, so we have plenty of time.'

I pulled both of them back into my arms and closed my eyes.

This night would indeed continue.

And tomorrow probably won't end that quickly either.
