When the door opened, I froze.
She was way hotter than her photo. Long, shiny purple hair hung in a thick braid over one shoulder, like silk just brushed. A few soft strands curled around her pale, perfect face. Her sharp cheeks and elegant jaw looked strong but soft. Big violet eyes stared at me calm and sharp like she could see through me.
She wore a dark-purple blouse, tight and shiny. It fit her body like a second skin. Her arms crossed under her huge, soft breasts. They pushed up high, almost popping out. The thin cloth hugged every round curve of her big, heavy tits. You can see deep, warm cleavage between them.
Her waist was super tiny, like a belt pulled hard. Then her hips exploded wide. The black skirt was glossy and super tight, like wet paint on her skin. It stuck to her thick, juicy thighs and big, round ass. The skirt stopped just above her knees, showing long, smooth, creamy legs.
The thick braid rested on one big breast. Her pale skin glowed. Full, soft lips looked ready to kiss. She stood neat, confident, in control, like a sexy boss lady who knows she's hot and owns every room.
She looked at me. For a moment, I felt like a small student standing in front of his teacher. I remembered my childhood female teacher. She was my first crush.
"Hmm? Who are you?" she asked.
Her voice was soft and dreamy, like music in my ears.
"What's wrong?" she asked again.
I took a deep breath. I pulled myself together and smiled.
"You are so beautiful. I lost myself for a second. Sorry. I am the… 'cuckoo' sent by the government. I look forward to working with you."
She blinked slowly. She looked at my face, my dyed blonde hair, my six-foot tall body, and my strong muscles. My body looked very masculine. But she did not smile or blush at my words. The praise did not matter to her.
"You are a little different than I imagined," she said.
I scratched my cheek. I felt shy. Her eyes made my heart beat faster. But I was proud of my new body in this world. So I spoke again.
"Ah… yes. People often say I do not look like a government worker. But you checked the Efficient Reproductive Mating Protocol letter, right? My code is 013."
She nodded slowly. She remembered the code. The government gives the same code to the cuckoo and to the couple. No one can share the cuckoo's real name or photo. It is for security and safety. But the cuckoo gets all information about the couple he will be with.
"Yes," she said.
She stepped back a little. She opened the door wider.
"Come inside," she said.
I followed her into the house. My eyes stayed on her thin, beautiful waist. It moved gently as she walked. It was like a sweet dream.
"So what about your husband, Mrs. Wife?" I asked. My voice was low and curious.
"He is at work…" she answered softly. "I will make tea. Wait just one minute, okay?"
"Ah, no… it's okay, Mrs. Wife," I stopped her. My smile was sharp and hungry.
She looked up. Her violet eyes were big and round, like purple jewels.
"You see," I said. My voice became low and rough, like a growl. "It is already getting really hard down here. So let's do it right away."
A soft pink color came on her cheeks. She looked down at the big bulge in my pants. It was growing bigger. I felt hot inside when I heard her husband was away. This was the best part of my job. The fun was about to start.
I stepped closer to her. The air felt warm between us. I touched the button of my pants with my thumb. My fingers shook a little from excitement.
"Can you take off my pants?" I asked her. My voice was deep and full of need.
She bit her lower lip. Her small hands moved slowly. She reached for my belt.
This was the moment. The threshold.
What I was about to do was not cheating; it was my work. Hearing that might sound strange, even crazy, but in this world it was not only legal, it was considered sacred.
That memory came back to me, just like it had during my first mission.This was only my second assignment, but the feeling was the same.
I wasn't born in this world.
I had come here by transmigration, waking up one day in a body that didn't belong to me. It felt strange, familiar in some ways, but different in others. It was taller, stronger, and filled with a kind of energy I had never felt before.
This world had already reached a dangerous stage. Its fate had been shaped by a quiet, hidden crisis that people rarely talked about, but everyone lived under its shadow.
This was not Earth. It was a different world, a world where some people were born with special powers and unusual abilities. These powers made society strong in many ways, but even they could not stop the slow collapse caused by the fertility crisis.
The crisis began quietly. At first, people did not notice anything. Couples who wanted children tried many things. They used medicine, potions, even new scientific methods and special magic spells. But nothing helped.
Fertility continued to fall.
Scientists and magicians studied the problem and finally found the reason. A virus was damaging the male reproductive system. Most men became infertile and could no longer produce healthy sperm.
Because the population was shrinking, one country created a new and very bold law.
It was called the Efficient Reproductive Mating Protocol, but many people simply called it the Cuckoo Law.
Miraculously only a very small number of men gained the ability to be fully fertileThese men were called Prime Donors. And I am one of them.
They possessed a rare biological trait: their seed could enhance a woman's fertility enough that she could conceive and bear a healthy child, even if her own husband was infertile.
When a couple yearns for a child but the husband's seed lacks strength, a Prime Donor is summoned. His semen carries two distinct abilities, and the couple chooses the path forward.
The first ability impregnates the woman directly. He floods her womb with thick, hot cum. His potent sperm swiftly meets her egg, and a baby, his genetic child, begins to grow.
The second ability enhances her fertility. He fills her just as completely, pumping wave after wave of powerful seed inside her. Instead of fertilizing the egg himself, his cum temporarily supercharges her reproductive system.
Her womb becomes extraordinarily receptive. When her husband makes love to her, even his weak or damaged sperm gains the power to penetrate the egg. The resulting child carries the husband's DNA, not the donor's.
The husband's involvement in the process depended on each couple.
Some husbands stayed in the room because they wanted to understand the process, but many chose not to watch. They felt uncomfortable, jealous, or simply emotional at seeing their wives in the arms of another man.
It was a personal choice, different for every family.
Even so, one rule was very strict: A Prime Donor could not be threatened or harmed. Interrupting the procedure was a serious crime. Prime Donors were protected by the government because their role was extremely important.
At first, many people were shocked and angry about the law.
Religious leaders, cultural groups, and ordinary citizens said it was unnatural and wrong.
But over time, the results became clear.
Birth rates increased. Healthy babies were born again. People slowly changed their opinions.
What was once taboo became normal.
After many years, the world fully accepted this unusual system of reproduction.
By the end of the century, fertility was rare and precious. Governments controlled it carefully. Prime Donors were respected and closely monitored.
Families had to balance love, duty, and responsibility.
Reproduction was no longer a private matter. It became a shared effort to protect the future of society.
In simple words, this world lets me fuck any woman I want and pays me for it.
A senator's polished wife, a red-carpet goddess, even the first lady, they all spread their legs. Lonely MILFs with heavy, soft breasts and needy widows with slick, warm hips open wide and beg for my rod.
I'll drive in deep, slow then savage, until their pussies drip and clench around me. I'll make them tremble, scream, and cum hard on every thrust. I'll pump them full of thick, hot seed until it spills out and stains the sheets. Cash slides into my pocket the second I zip up.
In my old life, I was nothing. Here, I'm a special, a chosen one. Every wish comes true in this world of endless, burning desire.
