My name is Guo Guo, I'm 19 years old, the youngest in the family. I have two older brothers. My eldest brother, Chen Wenzhong, is thirteen years older than me, and my second brother, Chen Wenping, is twelve years older. Today is the day my second brother is coming home on leave after finishing his new training.

Due to work, father is often abroad, rarely returning home a few times a year. Mother has always taken care of us at home. Mother's greatest wish was to have a daughter. After giving birth to two sons in a row, she was disappointed for a long time, even threatening father with divorce papers. Father hurriedly returned home and stayed for three months, which was the longest time he ever spent at home.

It’s just that when I was born, the doctor said into the phone to my father on the other end, “Congratulations, it’s a boy.” My mother broke down on the spot, grabbed a pillow, and threw it at my father. My father caught the pillow and said with a bitter smile, “From now on, he is a daughter.”

It was this sentence that completely changed my life. On the household register, I went from being the third son to the eldest daughter; even my grandparents and maternal grandparents treated me as a granddaughter. If my second brother hadn't inadvertently pointed it out after graduating from university half a year ago, I would have always thought I was a girl myself.

I look very much like my mother, with a small oval face, thin lips, and hair tied in a ponytail that reaches my waist. When dressed in a dress, I look more like a girl than many of the actual girls in my class. Boys always liked to surround me; some would pull my hair, but after pulling it, they would often get beaten by other boys, so eventually no one dared to touch me again.

Today my second brother is coming back, so I deliberately came home early. Just after closing the door, I was suddenly lifted from behind and pinned against the door panel. A hand forcefully turned my face, and a handsome face, much more tanned than I remembered, came close; hot lips sealed my mouth directly.

“I’m back—” Before she could finish saying it, his tongue swept it away.

Second Brother’s kiss was urgent and deep, carrying the longing of not having seen each other for more than a month. His body was pressed tightly against me, and even through our clothes I could feel that his lower body was already hot and hard, pressing against my buttocks. I had originally wanted to push him away, but my body gradually relaxed in the familiar scent, and I closed my eyes to return this deep kiss that had been delayed for so long.

By the time I came to my senses, he had already carried me to the sofa. My backpack was casually thrown on the floor, textbooks scattered everywhere. Second Brother had already taken off his shirt and pants, leaving only a tight black pair of briefs that were stretched taut. He stood in front of the sofa, looking down at me from above.

“Stinky second brother, look at how you’ve wrinkled someone else’s skirt!” I turned my head and said, pretending to be angry. But even I could hear that my tone sounded more like acting cute. My face instantly burned hot.

Elder Brother Two gave a low laugh, bent down and leaned by my ear, his voice hoarse and teasing: “Xiaoguo, do you know what you look like right now? A rosy little apple—just looking at you makes me feel sweet and juicy. I really want to swallow you whole.”

After saying that, he took my earlobe into his mouth, sucking gently. A tingling sensation immediately spread from my ear throughout my body, raising fine goosebumps. At the same time, his hand covered my right breast, gripping the small nipple through my clothes.

I curled up in pain, trying to dodge, but before I could even cry out, he had already taken my left nipple into his mouth. His warm tongue circled that point, sometimes gently nibbling, sometimes sucking hard.

“Mm... second brother...” I couldn’t help letting out a sound, my fingers gripping his shoulder.

He didn't stop. His other hand had already slid down along my waist and into my skirt. I was wearing the light, thin underwear I had specially chosen today, and his fingers easily touched that slightly raised softness. He clearly paused for a moment, then let out a low laugh.

“You’re still so honest...” He raised his head, his eyes darkening. “After I learned the truth half a year ago, I’ve been thinking about this day every day.”

My face flushed deeply, but I didn't actually push him away. Second Brother's fingers had already grasped that boyish thing, gently stroking. The unfamiliar yet familiar pleasure made me tremble lightly.

While continuing to work me with his hand, he lowered his head to undo the buttons on my dress. Piece by piece, my clothes were stripped away until my upper body was completely exposed to the air. Although I was raised as a girl, my chest had barely developed, with only two small points. Yet my second brother took care of them like treasure, alternately using his lips and tongue on them.

“Second Brother... don’t...” My voice softened, but my legs unconsciously parted a little.

He lifted his head and looked at me seriously: “Guoguo, look at me. You are my brother, and also the person I want most. When I go home today, I don’t want to see anyone else first. I only want you.”

As the words fell, he pulled down his briefs. That fully erect member sprang out, thicker than I remembered. He took my hand and guided me to touch it. The scalding sensation made my fingertips tremble.

Elder Brother Two bent down and kissed me again, while adjusting his position so that the two equally scorching things pressed together. His hand wrapped around us and began to stroke slowly. The intense stimulation made me involuntarily let out a soft moan, my body arching slightly.

“Relax...” he said softly in my ear, though his movements gradually quickened.

Pleasure built up quickly. I grabbed his arms, my breathing growing more and more ragged. Just as I felt I was about to reach the peak, he suddenly stopped, pulling back a little.

“It’s still early.” he said with a smile, then flipped me over completely and made me kneel face down on the sofa.

The skirt was completely lifted to her waist, and her panties were pulled down to her knees. I felt his fingers coated with something cool, gently probing into that untouched place behind me. The sensation of a foreign object made my body stiffen.

“Second Brother...”

“Will be very slow.” His voice was even hoarser than before, “If it hurts, tell me.”

He was really patient. His fingers slowly dilated me until I gradually adjusted to that feeling of being filled. When he changed to his own sex organ and pressed it against the entrance, my whole body tensed up.

"Breathe." He patted my waist.

I did as told. He pushed in slowly and firmly. The stretching ache made me bite my lower lip, tears almost falling. He stopped to let me adjust, his hand reaching around to continue stroking that thing in front of me, which was already hard and aching.

I don’t know how much time had passed when the pain gradually gave way to another strange sense of fullness. He began thrusting in small motions. Each entry went a little deeper, until he was completely inside.

“So tight……” he panted, his forehead pressed against my back.

After the real action began, the sofa made a slight creaking sound. I was pushed forward by him, my hands gripping the back of the sofa tightly. The initial discomfort gradually transformed into intense pleasure, burning from the point of union all the way to my mind.

“Second Brother... slo, slower...” My voice was halting, yet honestly welcoming him back.

But he seemed to have finally released the long-suppressed desire in him, and his speed gradually increased. The pouch slapped against my buttocks, making a crisp sound. The thing in front of me was being continuously stroked in his hand; the stimulation from both front and back made me quickly reach my limit.

The white, turbid liquid shot onto the sofa. At the same time, I felt him pulse a few times inside me, and a stream of scalding liquid poured in.

He didn’t withdraw immediately, but kept the connected position, holding me from behind, his lips pressed against the back of my neck.

"Welcome home." I panted, my voice still a little hoarse.

He chuckled lowly and nipped my shoulder. “That’s the line I should be saying.”

We rested in this position for a while. Outside, the sky gradually darkened. Mother was working overtime today, and my older brother wasn't home either. For the time being, the entire house belonged only to the two of us.

When Second Brother finally pulled out, I felt warm liquid trickling down the inside of my thigh. He pulled me up and carried me straight into the bathroom.

The bathroom light was brighter than the living room's. For the first time, I saw so clearly how I looked after being used—hair disheveled, lips swollen, his fingerprints and kiss marks left on my body. Second Brother hugged me from behind, his hands covering my chest again.

“Does it still hurt?” he asked.

I shook my head, leaning against his chest: 'It's a bit strange... but...'

“But liking?” he picked up the thread, his fingers already grasping the thing in front of me again, gently stroking it.

I didn't deny it.

Steam quickly filled the bathroom. Second Brother wasn't in a hurry to enter from behind this time. Instead, he turned me around so we faced each other. He lifted one of my legs, had me lean against the wall, and slowly pushed into the place that had just been opened up.

This time went much smoother. Hot water washed over our bodies, but his movements grew deeper and deeper. I wrapped my arms around his neck, buried my face in the crook of his shoulder, and endured the repeated impacts.

After who knows how long, he released inside me again. I, too, was stimulated from front and back and came a second time.

While we were washing up, Second Brother suddenly spoke up: 'Does Big Brother know about this?'

My movements halted: "...Are you planning to tell him?"

"No." He stroked my hair, his voice calm. "But I think he probably already knew I liked you. Just like I also know his gaze when he looks at you isn't only that of a brother."

I fell silent.

Some things, once they begin, are difficult to pretend they don't exist.

When I came out of the bathroom, it was already completely dark. Second Brother carried me back to the room, and the two of us lay naked on the bed. His fingers slowly moved over my smooth back, as if confirming something.

“Guoguo.” He suddenly called my name. “Starting today, in this family, you are not only a younger brother, and not only Guoguo who was raised as a daughter.”

I turned to look at him.

"You are mine." He said word by word, his gaze so serious it made my heart race.

I didn't answer, just actively leaned over and kissed his lips.

This kiss was much gentler than the first, but longer. By the end, I felt his body reacting again, the hard part pressing against my thigh.

“Still want more?” I asked softly.

He chuckled lowly and flipped me over onto himself, letting me straddle him: “The night is still long.”

I braced my hands on his chest, slowly lowering myself. The feeling of being filled washed over me again, but this time with a familiar sense of comfort. I began moving up and down on my own, while he lay on his back, hands on my waist, letting me control the pace.

Moonlight leaked through the gap in the curtains, shining on our entwined bodies.

Suddenly, the sound of a key turning came from outside the door.

I froze completely. Second Brother also immediately stopped his movements, his eyes instantly turning alert.

Was it Mother returning? Or Big Brother?

We held our breath, listening to the movements outside. The footsteps paused in the living room for a moment, then headed toward the master bedroom. The door was gently closed.

Elder Brother Two and I looked at each other, and both saw in the other’s eyes the lingering lust that had not yet faded, as well as a trace of luck.

“Looks like it’s Mom.” He said softly, but his hand once again gripped my waist, “Then shall we... continue?”

I bit my lower lip and nodded.

This time we both tried our best to keep our voices down. Each thrust was shallow and slow, yet the necessity of suppression made it even more thrilling. I lay on his chest, burying my face in the crook of his neck, bearing the force of his gradual upward pushes.

When the climax came again, I bit down hard on his shoulder to keep myself from making a sound. He also released inside me, his body tensing for several seconds before slowly relaxing.

We lay quietly for a long time, still connected.

The light in the main bedroom outside had already gone out. The entire house fell back into silence.

Second Brother’s fingers drew circles on my back, and he suddenly said, “Big Brother will be back tomorrow too. What do you plan to do?”

I was silent for a moment before saying softly: 'Let's leave it like this for now. Take it step by step.'

He gave an “mm” and held me even tighter.

That night, we did it once more before finally falling into a deep sleep.

When I woke up in the morning, Second Brother was no longer by my side. A note was left on the bedside:

“Get down and eat breakfast. I’ll make it today.

— 'Second Brother'

I propped up my still somewhat sore and weak body and sat up, looking at my reflection in the mirror—there were faint kiss marks on my neck, my lips were slightly swollen, but my eyes were brighter than ever before.

Some secrets, once started, are destined to be carefully hidden away in daily life.

And I know that this is just the beginning.

Big brother will be back soon too. Mother has always seen me as a daughter. Father is far away abroad.

Within this 19-year-old body raised as a girl lies a boy's true self, and a newly, thoroughly awakened, forbidden desire for his older brother.

The door was pushed open a crack. Second Brother peeked in, saw I was awake, and smiled with his eyes crinkling:

"Come down. The porridge is ready."

I nodded, picked up my clothes, and slowly put them on.

As we reached the door, he suddenly reached out and pulled me, quickly pecking my lips.

“Remember,” he said softly, “in this family, you're my Guoguo.”

My ears grew hot, but I didn't argue, just softly 'mm-hmm'ed, then followed him into the living room.

The sun had already entered the house.

A new day has begun.

And the secret that belongs to us has only just written its first stroke.

When the morning sunlight spilled through the gap in the curtains into the living room, Second Brother was already dressed neatly and standing in the kitchen. He was wearing the old apron our mother often used, stirring the congee in the pot. When the lid was lifted, the aroma of rice mixed with a hint of scallion wafted over. I stood at the bedroom door, still wearing the loose T-shirt I grabbed last night, the hem just covering the top of my thighs. Because of last night's exertions, my legs were still a bit weak, and when walking, I could faintly feel the lingering unusual sensation behind me.

Elder Brother Two turned back and saw me. His gaze darkened for an instant, then returned to that usual expression with a hint of a roguish smile.

“Come down and sit. The porridge is just right.”

I walked to the dining table and sat down. The bowls and chopsticks were already set. He served a bowl of porridge and pushed it toward me, then added two pieces of the fried eggs he had made himself. His movements were as natural as if he had done this countless times. But when he sat down opposite me, his foot gently brushed against my calf under the table.

"Did you sleep well last night?" he asked, his voice calm, but his eyes fixed on me.

I lowered my head to drink the porridge, my ears burning: 'It's okay... a bit sour.'

He gave a low chuckle and said no more. In the living room, only the soft clink of a spoon against a bowl could be heard. Mother had come home very late last night and was still sleeping in the master bedroom. The whole house belonged to just the two of us for the time being.

Halfway through the meal, Second Brother suddenly put down his chopsticks, got up, and walked to my side. Before I could react, he had already bent down from behind, braced both hands on the edge of the dining table, and caged me in his arms. His warm breath blew against the back of my ear.

“The skirt?” he asked.

"...haven't changed yet."

"Then don’t change it." His hand slipped in beneath the hem of my T-shirt, his palm pressed against my flat belly as he slid upward until he held one side of my tiny nipple. His fingertips kneaded it lightly, then a little more firmly. My body stiffened, and the spoon nearly fell into the bowl.

"Second brother... Mom is still here..."

"She's sleeping very soundly. And—" He bit my earlobe and lowered his voice, "I want you once at breakfast."

As the words fell, he had already pulled me up from the chair, making me brace my hands on the dining table. My T-shirt was pulled up above my chest, and the entrance behind, still carrying the afterglow from last night, was easily probed by his fingers. Thanks to the preparation from the previous night, this entry was much smoother. He simply stretched it a few times, then undid his own pants and thrust in.

“Mm……”

I bit my lower lip, trying not to make a sound. The morning sun shone on our intertwined bodies. Each of his thrusts was deep and slow, as if deliberately making me feel the entire process of being filled. The table swayed slightly with the movement, and the bowls and chopsticks made faint clinking sounds.

"Squeezing so tightly..." he panted, one hand holding my already-risen penis in front and slowly stroking it, "Didn't we just do it last night?"

I shook my head, unable to form a complete sentence. The pleasure came more directly than last night. Perhaps it was because we were in the living room, and the tension of someone possibly waking up at any moment made my nerves more sensitive. Before long, I released in his hand, the white, thick liquid splattering on the edge of the dining table. He then quickened his pace, thrusting inside me a dozen more times before letting out a low groan, releasing everything inside.

When he pulled out, warm liquid trickled down the inside of my thigh. He took a tissue and wiped me briefly, then sat back down as if nothing had happened, continuing to drink his porridge.

"Big Brother will be back today." He suddenly spoke.

My movements halted: "...I know."

"He’ll probably stay for a few days. During this time, we have to be careful."

I nodded. But a vague, complicated feeling welled up inside me. Eldest Brother had always been quiet and reserved; his attitude toward me, raised as a younger sister, had always been one of faint indulgence. But Second Brother's words last night, "The way he looks at you isn't just as a younger brother," kept spinning in my head.

In the morning, after Mother got up, the atmosphere at home immediately returned to normal. Seeing the breakfast made by her second brother, she smiled and ruffled his hair: “You’re so sensible after coming back from training? You used to not even wash a bowl.”

Second Brother shrugged, but his eyes quietly drifted toward me.

In the afternoon, the eldest brother’s car stopped downstairs. He was a bit taller than the second brother, with a composed demeanor. After entering, he first put down his luggage, then came over to me and reached out to pat my head.

“You’ve grown a little taller.” He said, his voice deep.

That hand seemed to linger a bit longer than usual. I instinctively took half a step back, my heart inexplicably speeding up.

During dinner that evening, the atmosphere appeared peaceful on the surface. Mother asked Second Brother about his new training and asked Big Brother if his company was doing well lately. Second Brother occasionally interjected with a few jokes, making Mother laugh. I quietly picked up food with my chopsticks, feeling a foot gently touch my calf under the table—it was Second Brother.

At night, shortly after I returned to my own room, the door was gently pushed open. Second brother slipped in, locking the door behind him. He was only wearing loose lounge pants, his upper body bare.

“Big brother fell asleep?” I asked softly.

"Mm. Mom has gone back to her room too." He walked over and directly pinned me onto the bed, "I missed you."

This time there wasn't much foreplay. Clothes were quickly stripped off, and two bodies pressed tightly together. He entered me from the front, but his movements were much more restrained than in the morning, each thrust shallow and slow, careful not to make too much noise. My legs wrapped around his waist, fingers digging into his back muscles.

"Gently... it'll be heard..."

"Then squeeze tighter." He bit my lower lip and said softly, "Don’t make a sound."

Pleasure was amplified by the suppression. I buried my face in the crook of his neck, enduring each deep thrust. I don't know how long passed when he suddenly lifted me up entirely, making me sit on top of him. This position went even deeper; I felt almost completely impaled. Holding my buttocks, he moved me up and down, his breathing gradually becoming ragged.

Just as both were nearing their climax, footsteps suddenly sounded in the corridor.

We both froze at the same time.

The footsteps paused for a moment at my bedroom door, then continued forward into the bathroom. It was my eldest brother.

Second Brother didn’t pull out; he just stayed fully buried, his forehead against mine, his eyes carrying a hint of dangerous excitement.

"Don’t make a sound." He said it in a breathy whisper.

The sound of water from the bathroom went on for a long time. We maintained a tightly connected posture, and neither of us dared move. After the sound of water stopped, and footsteps passed by the bedroom door again before fading away, Second Brother resumed his actions. This time he no longer restrained himself, thrusting upward fiercely. I bit down hard on his shoulder and reached climax in the intense pleasure. He also released inside me at the same moment.

Afterward, we were both somewhat drained. He didn't leave right away, but instead gathered me into his arms, his fingers slowly moving over my sweat-damp back.

"One day," he suddenly said, "I want to let big brother know too."

I looked up at him.

"Not now." He added, "But one day. In this house, there shouldn’t be only me who knows what you really look like."

I was silent for a long time, finally burying my face back into his chest.

"...let's talk about it later."

The next few days, the family maintained a superficial calm. During the day, we interacted like ordinary brothers, and at night, Second Brother would find opportunities to slip into my room. Sometimes it was just hugging and kissing, sometimes it would go as far as two or three times. After each time, he would carefully clean me up, ensuring no obvious marks were left.

But some things, after all, cannot be hidden.

On the evening of the fourth day, when I returned to my room after showering, I found my eldest brother sitting at my desk. He was holding an old photo album of mine, turned to a picture of me wearing a princess dress as a child.

“You liked this dress a lot when you were little,” he said without turning his head.

I stood at the door, somewhat at a loss: '...Big brother?'

He closed the photo album and turned around. His gaze was deeper than usual.

"Second Ping has been running to your room every night lately."

The air instantly froze.

I opened my mouth, but no sound came out. Big Brother stood up and walked over to me. He was much taller than me, exuding a strong sense of intimidation.

"Did he touch you?"

The question was blunt, almost cruel. I lowered my head, fingers twisting the hem of my clothes.

The silence lasted over ten seconds. Finally, I nodded very lightly.

Big brother didn't get angry, nor did he show an expression of disgust. He just looked at me, for a long time.

"Since when did it start?"

“...He came back the day his training ended.”

He fell silent again. After a while, he reached out and lifted my chin, forcing me to look into his eyes.

“Does it hurt?”

I froze.

"The first time, did it hurt?" he repeated.

My ears grew hot, and I softly 'mm-hmm'ed.

The older brother's thumb brushed against my lower lip, the action unclear whether it was soothing or something else. Then he let go, took a step back.

"Don’t let him in tonight."

“Big brother—”

“I’m telling you, don’t let him in tonight.” His tone left no room for negotiation, “There are some things I need to think through first.”

After saying that, he turned and left, closing the door behind him.

I stood there, my heart pounding wildly.

That night, Second Brother indeed didn't come. I lay in bed, listening to the faint sounds from Eldest Brother's room next door, unable to fall asleep for a long time.

The next morning, only my eldest brother and I were left at home. Mother had gone to work, and second brother had been invited out by friends.

The older brother made a simple breakfast and called me out to eat. We sat facing each other, the atmosphere was subtle.

Halfway through the meal, he suddenly said: “Come here.”

I put down my chopsticks and walked over to him. He grabbed my wrist and pulled me onto his lap. This position was overly intimate, and my body stiffened.

"Relax," he said in a low voice, his palm pressed against the small of my back. "If Bian Ping can touch it, why can't I?"

I suddenly raised my head.

The older brother's eyes were very calm, yet they carried an aggression I had never seen on his face before.

"You are our younger brother, and also Guoguo, who was raised as a daughter in this family. Erping can have you, and so can I."

As the words fell, his hand had already slipped under the hem of my clothes.

I didn't resist.

Perhaps from long ago, some boundaries had already become blurred.

The older brother's movements were more steady and less demanding. He didn't rush to enter, but instead spent a long time kissing and caressing my body. When I was already unable to resist, he placed me on the dining table, spread my legs, and slowly and firmly pushed in.

"Tighter than I thought..." he gasped, pressing his forehead against mine, "Does Er Ping do this to you every day?"

I shook my head, unable to form a complete sentence.

Big brother began thrusting. Each stroke was deep and heavy, the table making slight noises with the movement. I grabbed his arms with both hands, enduring this rhythm different from second brother's. Pleasure accumulated quickly, and I soon released beneath him. He didn't hold back for long either. After releasing inside me, he remained buried within, not withdrawing.

"From today on," he lowered his head and kissed the corner of my eye, "you’re not just Erping’s."

I closed my eyes and softly hummed 'Mm-hmm.'

Some secrets, once shared by two people, can never go back to how they were before.

At noon, when Second Brother came back, the house had already returned to its usual state. But when he saw the faint kiss mark that had appeared on my neck, his gaze instantly darkened.

“Big brother?” he only asked two words.

I nodded.

Second Brother was silent for a few seconds, then suddenly smiled. There was helplessness in that smile, and also a strange sense of relief.

"I knew it would be like this." He came over and kissed my lips. "Then let's go together."

In the evening, after Mother fell asleep, my two older brothers entered my room one after the other.

The door was locked.

The lights were turned off.

Under the moonlight, three young bodies entwined. Second brother entered me from behind, while eldest brother made me take him in my mouth. Two completely different sensations and rhythms stimulated my senses simultaneously, leaving me almost unable to think.

“It doesn’t matter if you cry out…” My second brother bit my earlobe and whispered, “Anyway, Mom sleeps very deeply.”

But I bit down hard on my lower lip, only letting out fragmented whimpers from my nose.

This night was long.

They took turns using my body, and occasionally entered different places at the same time. Orgasm came again and again until I was almost exhausted. In the end I lay on the bed and felt warm liquid flowing out from behind and in front at the same time, mixing together and trickling down my thighs.

The two older brothers lay on either side of me, their hands still on my body.

"From now on, it’ll be like this." Big Brother’s voice sounded in the darkness, calm but with an unquestionable tone.

Elder Brother Two let out an “Mm,” burying his face in my hair.

I didn't speak, just took each of their hands in mine.

Some relationships, once they cross a line, can never be taken back.

And this nineteen-year-old body, raised as a daughter, now completely belonged to these two men connected by blood.

The sky outside the window gradually brightens.

A new day is about to begin.

It’s just that this time, the secret has gone from two people to three people. And the story has only just begun.
