My name is Jamal. Before the Great Change, I was a 28-year-old German man, muscular and athletic, with fair skin and short blond hair. I worked as a personal trainer at a gym. I liked my body: broad shoulders, strong arms, and the attention I received for staying in shape. My life revolved around training, healthy eating, and taking care of my physique.

That day I opened my eyes in front of a mirror in a bathroom I didn't recognize. I was wearing white headphones and holding a phone. I looked down and saw a torso that wasn't mine: dark skin, defined abs and chest, and messy black dreadlocks falling over my forehead. I was wearing light beige pants, one hand in my pocket with a watch, and bracelets on my wrist. The voice that came out of me was deep and resonant, with an accent I didn't recognize.

The shock was brutal. I stood there staring at my reflection for a long time, touching my face, arms, and hair. I had gone from being a white, blond, muscular, fair-skinned man to a Black man with dreadlocks. The color of my skin had completely changed, the texture, even the way my hair fell. I felt invaded and totally out of place. Walking felt different; my shoulders swayed differently, my stride was longer. I kept touching my chest and arms: the muscles were still firm, but the skin tone and everything else felt completely alien. At first, it was very hard. People treated me differently: more smiles, longer glances, more fluid conversations, but also some reactions of surprise or curiosity because of the racial change. I, who used to be an extrovert at the gym, now felt exposed in a completely new way.

Over time, I began to notice the advantages of my new body: increased stamina, natural strength. But what changed the most were my sexual preferences. Before, I was primarily attracted to women and considered myself heterosexual. Now, in this defined Black body, I discovered that I'm very attracted to men. I get turned on by the way they look at me, how they touch my torso and dark muscles. I started sleeping with guys regularly. I have sex several times a week, sometimes more. I love it when they suck my cock while I'm standing there with my headphones on, or when they fuck me from behind and I feel my abs tighten with every thrust. I come hard and fast in this body, and the feeling of being desired by men excites me immensely.

I still masturbate a lot, especially after working out or when I look in the mirror and see my dreadlocks and my tan. It excites me to see how this new body responds. It's disgusting how often I have sex now, but I can't help it. The pleasure is more intense, more direct. I'm still me inside, but this body has its own strong desires, and I'm learning to let go.

Ana

My name is Ana. Before the Great Shift, I was a 26-year-old woman working as an accountant in a small office. I spent my days sitting in front of a computer, with my ordinary, slim body: 1.65 meters tall, narrow shoulders, soft arms and legs with no real muscle tone. I had short black hair and lived a quiet, routine life with my girlfriend Laura.That day, everything changed in a single second.

I opened my eyes and found myself standing on pink and black mats in a dojo I didn't recognize. I looked down and saw a torso that wasn't my own: broad, rounded shoulders, prominent pecs, defined abs, thick arms with visible veins. I was no longer wearing a shirt, just black pants with red stripes and a gray belt tied around my waist. My feet felt bigger and heavier. When I touched my chest, the muscles felt firm and dense. I instinctively flexed my arms, and my biceps bulged so much that I was breathless.

The voice that came out when I muttered, "What the hell is going on?" was deep and hoarse. I felt invaded, exposed, and completely out of control. This body was too big, too masculine. At first, I walked awkwardly; my shoulders wanted to spread apart, and my center of gravity had shifted completely.

At that very moment, Laura woke up in the body of a man in his early thirties: tall, somewhat thin, with a small belly, pale skin, and short, dark hair. Later, she told me that she stared at her large, rough hands, touched her flat chest, and felt the weight between her legs. She screamed my name in a hoarse, masculine voice she didn't recognize and panicked. She felt lost, stripped of her curves and softness, as if her own body had been stolen. When we finally met a few hours later, it was devastating. I, with this muscular, shirtless torso, saw a strange man approaching. She, in her new male body, saw me as an athletic guy. We recognized each other by our voices and the way we spoke, but we both burst into tears.

We recognized each other by our voices and the way we spoke, but we both burst into tears. We recognized each other by our voices and the way we spoke, but we both burst into tears.

The hug felt awkward and inappropriate: I was taller and much broader, while she felt uncomfortable with her new height and lack of curves. We both felt vulnerable and embarrassed. I missed my small, familiar body; she missed her breasts, her hips, and her soft voice. It was hard even to look each other in the eye without feeling like we were with strangers.

The first few days were brutal. I felt constantly watched. People stared at me for longer periods, some with admiration. Laura felt awkward and unattractive in her new body. Intimacy felt strange and difficult at first. Over time, everything changed, including our sexual preferences. Before,

I was completely lesbian and only attracted to women. Now, in this muscular male body, I get turned on much more easily by men. I like the way they look at me, how they react to my physique. After training I stay shirtless in front of the mirror, run my hands over my hard torso, and end up jerking off several times a day. The sensation is so intense I can’t stop; this body responds so fast and powerfully that I cum much harder and easier than before.

Laura changed too. She used to be lesbian like me, but now in her male body she feels a strong, urgent attraction to women. We started having sex almost every day. Sometimes I fuck her with this big, powerful body, other times she sucks my cock while I flex my arms and abs for her. We love watching ourselves in the mirror while we fuck: me shirtless and sweaty with my muscles pumped, her thrusting against me in her new body. It’s pure filth, but it turns us on like crazy.

Lucas was the youngest son in a family of six living in Monterrey: his mother, his father, and his three older brothers — Diego, 25, Mateo, 22, and Alex, 20. At 12 years old, Lucas was a thin, short boy for his age, and his greatest passion was Kanye West, especially the famous teddy bear that appeared on the album covers.

He constantly dreamed of growing up and becoming an adult so he could join his brothers at concerts. Every time he saw Diego, Mateo, and Alex getting ready to go out, he would ask them hopefully: “When I grow up, can I go with you to see Kanye West live?” His brothers would smile and tell him affectionately that yes, but that he still had a long way to go.

One Saturday afternoon, while his brothers were playing in the living room, Lucas went down to the basement looking for a lost ball. Among old boxes and forgotten objects, he found a very old CD player and, next to it, a silver disc without a cover. On the surface of the disc, his name was written in black marker: “Lucas."

Curiosity was stronger than fear. He placed the disc in the player, pressed play, and sat down on an old box to listen.

At first, a slow and familiar Kanye West beat played, but soon the sound became strange, as if it carried a deep echo that vibrated inside his body. An intense heat began to run down his spine.

Suddenly, his bones began to crack. Lucas felt his body stretch rapidly. His legs and arms lengthened swiftly, growing from his childlike height to nearly 1.60 meters in a matter of seconds. The loose t-shirt he was wearing now pressed against his shoulders and chest. His muscles began to develop: his arms grew thicker, his shoulders broadened, and, most notably, his chest expanded noticeably. His pectorals became round and firm, clearly defined beneath the fabric of the t-shirt. His abdominal muscles appeared one by one, taking shape as if someone were sculpting them. His legs became muscular and strong, and his face changed: his jawline became more defined, his cheekbones rose, and his eyes acquired a more mature expression.

Startled, Lucas tried to turn off the player, but his hands were shaking. The process continued. He kept growing until he reached exactly 1.86 meters in height. His physique transformed into that of an athletic young man who trained regularly at the gym. His pectoral muscles became even more prominent and defined, pressing against his t-shirt until it ripped in half with a sharp snap. His shoulders and back broadened considerably. His abdomen transformed into a perfect set of well-defined eight-pack abs. His face matured completely: more defined features, a light stubble on his jaw, and a deep, mature voice that no longer belonged to a child.

When the transformation was complete, Lucas was 18 years old. His boy's clothes were now tiny and torn in several places. His heart was pounding as he ran upstairs to his room.

Upon entering, he stopped dead in his tracks. The room was no longer that of a twelve-year-old boy. Now it had a large bed, enormous Kanye West album posters on the walls, adult clothes neatly arranged in the closet, and a pair of Yeezy sneakers in the corner. Everything had changed.

He approached the closet mirror and stared at himself in disbelief. With trembling hands, he removed the remnants of the torn t-shirt and stood in front of the mirror, his torso bare.

His new physique was impressive. His pectorals were thick, round, and perfectly defined, with a deep groove in the center. His abdominal muscles were clearly visible under the skin. His shoulders and arms showed hard, well-developed muscle. He slowly ran his hands over his chest, feeling the firmness and warmth of his new musculature.

Then he felt a different wave of heat. Inside his now too-tight pants, his penis hardened quickly, growing until it completely filled the fabric. It was the first time he experienced such an intense, adult desire. Unable to contain himself, he pulled down his pants and boxers, standing completely naked in front of the mirror. He began to masturbate while watching himself. One hand moved up and down rhythmically over his erect member, while the other squeezed and caressed his pectorals. The pleasure was overwhelming. His moans, now deep and masculine, filled the room. Moments later, he reached an intense orgasm, ejaculating powerfully onto the mirror and his own torso.

Breathing heavily, he picked up the new phone that was on the dresser and took several selfies: first a full-body shot showing his defined torso, then one squeezing his pecs with one hand, and some more intimate ones where he was still holding his semi-erect penis.

She had barely finished washing up and putting on a tight black t-shirt that perfectly accentuated her new chest when the bedroom door opened.

"Lucas, we're late for the concert," said Diego, his older brother, calmly. "The others are already waiting for us in the car. Are you ready?"

Lucas remained silent for a moment. Diego looked at him as if nothing strange had happened, as if Lucas had always been that tall, athletic 18-year-old.

Reality had completely changed. No one remembered the 12-year-old boy. For everyone, Lucas had always been the fourth brother, the youngest but already an adult.

She quickly dressed in jeans that fit her perfectly and her new Yeezy sneakers. Before leaving, she grabbed the teddy bear she still had and took one last selfie with it, smiling in front of the mirror.

He went downstairs with Diego. In the car, Mateo and Alex were waiting for him and greeted him normally.

As they drove to the stadium, Lucas felt a deep emotion. He was finally old enough. He was finally going to a Kanye West concert with his older brothers, just as he had always dreamed.

The architecture class from the university arrived early at the construction site of the new shopping center on the outskirts of the city. The sun was already strong even though it was only ten in the morning. All the students wore safety helmets and bright reflective vests. Professor Ramírez walked ahead, explaining in detail the process of placing the floor slabs and the importance of the reinforced concrete structure.

Among the students was Mateo, a seventeen-year-old boy. He had wavy black hair that peeked out from under his yellow safety helmet, large brown eyes, and a facial expression that mixed innocence with a hint of mischief. His skin was fair, with a few light freckles on his cheeks. He was slim but athletic, with a well-formed youthful body. At that moment, he was wearing a fitted black t-shirt, an open orange reflective vest, and he was making the “shaka” sign with his hand — index finger and pinky extended — while someone took his photo.

A short distance away, working among the construction materials, was Mr. Chuy, a forty-two-year-old construction worker. He was a robust man, with skin tanned by constant sun exposure, strong arms, and a broad torso shaped by years of physical labor. He wore a gray t-shirt that was worn and damp with sweat.

Mateo stepped away from the group to take more photos with the concrete structure in the background. Mr. Chuy, while lifting some blocks, looked up and smiled when he saw the gesture the young man was making with his hand. At that exact moment, a ray of sunlight reflected off an old broken mirror that someone had left abandoned among the debris. A bluish flash of light crossed the air between them.

Both blinked at the same time.

When Mateo opened his eyes, he felt that his body had completely changed. His hands were now larger, calloused, and tanned. When he touched his face, he felt a rough mustache and broader cheeks. He looked down and saw a wide chest covered in hair. He was inside Mr. Chuy’s body.

At the same time, Mr. Chuy felt a strange lightness. He looked down and saw a black t-shirt, an orange reflective vest, and young, smooth hands. He touched his face: there was no mustache anymore, only smooth skin with a few freckles. When he tried to speak, his voice came out clear and youthful. He was in Mateo’s body.

The two stared at each other with wide eyes and, without saying a word, quickly hid behind a thick concrete column so that no one from the group would see them.

Mateo, now in Mr. Chuy’s body, examined himself with disbelief. He touched his new strong arms, his broad chest, and his firm abdomen. He felt powerful, but also disoriented and strange.

Mr. Chuy, in Mateo’s body, looked at himself in the reflection of a nearby glass panel. First, he slowly pulled the black t-shirt over his head and let it fall to the ground. He remained only in the open orange reflective vest and the yellow helmet. The sun illuminated his new torso: a flat and smooth chest with just a light patch of dark hair beginning to grow in the center. His abdominal muscles were naturally defined, though not exaggerated, and his waist was narrow. He had youthful shoulders and slender but well-defined arms.

He ran his hands over his chest with curiosity, feeling the softness of the skin. He slowly moved down to his abdomen, touching each muscle with attention. Then he turned his torso to see himself from the side: his back was straight, his waist slim, and his shoulders had that characteristic youthful shape. He touched his sunken navel and continued exploring with his fingertips.

Without hurry, he removed the reflective vest completely and held it in one hand. Now he was completely shirtless, wearing only the yellow helmet on his head. The sun shone directly on his fair skin. He observed his new body in detail: the small, pink nipples, the line of hair that descended from his chest and disappeared under the waistband of his pants, and the athletic yet still youthful shape of his abdomen and chest. He flexed his arms slightly and saw how his biceps became defined. A smile formed on his face, using the same mischievous expression that Mateo usually had.

“This is… incredible,” he murmured with Mateo’s voice, while he continued touching his abdomen with both hands.

Mateo, still in Mr. Chuy’s body, watched him from the other side of the column, feeling increasingly uncomfortable.

“This cannot be happening,” he said with Mr. Chuy’s deep, gravelly voice. “We need to find a way to return to our bodies before anyone notices us.”

Mr. Chuy (in Mateo’s body) did not seem to be in any hurry. He put the reflective vest back on, but left it open, revealing much of his bare torso. He adjusted the yellow helmet and looked at himself once more in the reflection.

“I have never had a body like this,” he commented, running his hand over his abdomen again. “It is light, agile… and it looks good.”

Mateo stepped a little closer, still getting used to his new height and strength.

“Please do not do anything strange with my body,” he requested, though his deep voice contrasted with his worried tone.

Mr. Chuy smiled with Mateo’s face and raised his hand, making the same “shaka” gesture the young man had made earlier.

“Do not worry. I am only… getting to know the new owner of this body. And I must admit that I like it quite a lot.”

The noise of the machines and the voices of the professor and the other students could be heard in the distance. No one seemed to have noticed their absence yet. Mr. Chuy, still fascinated, took another photo with Mateo’s phone, posing with the vest open and his torso partially exposed, exactly as in the images you had shared.

Mateo sighed deeply inside Mr. Chuy’s robust body.

“How long will this last?” he asked.

“I do not know,” replied Mr. Chuy, still admiring his reflection. “But while we find a way to reverse it, I think I am going to enjoy this experience a little.”

They looked at each other in silence. One was surprised and worried about his new strong and experienced body. The other was clearly entertained and curious about his young, light, and attractive body.
