Sanji went straight to the laboratory to find the Scientist Nami.
"You!" He yelled. "What the hell is going on here?" "What do you mean," The Scientist Nami asked. "That girl with the braces, she was lactating. She was a child only a week ago and now, she's developed to the point where's she already lactating?! What's the meaning of all this?!" The Scientist Nami sighed and went to Sanji. She took out a cigarette from his pocket and began smoking it.
"It's time you learned the truth," She told him. "About our society."
Long ago, there was a tribe of women that were isolated from their homeland. They were a nomadic group, moving from area to area. Their genetics were unique in that the women's offspring were only female, and usually had their magenta hair and brown eyes, with some exceptions. They were known as the Bellemere Tribe, and it was said that that same tribe would go on to pave the way for our society, Namiville.
This ancient tribe would actively seek out men they deemed worthy of mating and kidnap him. He was forced to make love to all of the qualified adults and bear his children. After he did his task, he was killed. The tribe would move on to another man of their choice, and so on and so forth.
But their motives were made public, and they were targeted by nearby towns and villages. When they were captured, the tribeswomen were burned alive, lynched or beheaded. If one were pregnant, the child was not spared, with very few exceptions depending on the mob. The Bellemere Tribe was reduced to a few individuals. The leader of the small group gave birth to a young girl with red hair. The other women who were pregnant also birthed redheaded girls.
The man in question was a smiling seafarer, who saw no need to report the tribe's whereabouts. He would take care of the children and women, providing them with homes around the world. As the years passed, the tribe would reunite and form a new society. The majority of the women were now redheads, with few of the original tribe alive and elderly.
"…and at some point, we would go on to name our society after the first redheaded individual who saved our culture and ancestors, Nami." The Scientist Nami took a drag. "We've managed to keep ourselves concealed from the outside world for four centuries. And honestly, I'd like to keep it that way." She pulled out the same tranquilizer from before and fired a dart at Sanji, who dodged it.
"That's an interesting story," He said. "But it doesn't justify what you're doing to these children! And my food, which I take the utmost care in preparing…you sullied it with that artificial trash!"
"Well, aren't you the purist."
"You damn woman, I'm gonna…" He went to kick her, but couldn't. "Damn it…" He looked around. "I'll destroy this lab. It's the only way!" He up-ended tables, destroyed the samples, research papers and the like. The Scientist Nami fired darts nonstop.
"Damn you, this is viable information you're destroying!"
"Shut up! I won't stand for your practices!" He went to tilt a bookcase over when she came to his side. "I know your secret," She said. "You can't hit a woman, now can you?" She pulled out a knife. "Either surrender now, or I'll stab you in the heart."
"I won't let you do such a thing!" He went to grab her and she yelped in fear. His spine gave away and he backed down.
"Fool." She stabbed him, but not with the knife. It was a tranquilizer dart. "Your usefulness has run its course," She said. "It's time for you to see what happens to all of the men that come in our society…" Sanji's vision got blurry.
…
"…you're awake," A voice said. It was an old woman in a cloak. "You need not worry. You are in a good place. Sanji saw himself hooked to a machine. His penis had a cup on it, connected with a tube and his mouth, also connected to another cup with a tube leading upwards into a glass chamber. In the chamber, was a Nami whose breasts were being milked, contents dripping down into the tube to Sanji's mouth.
"Such a serene fate, no?" The old woman asked. "You'll be nourished by our lovely specimen's milk, made possible by our hormones and in return, your body will produce the substance of life needed to repopulate our lost society."
"Lost society…wait, she must be…" The old woman had faded but noticeably pink hair. "How old is this woman?" Breast milk came from the tube above. Sanji tried his best not to drink it, but the cup only made him swallow it.
"I can't stay here!" He thought. "My body is numb! I can't feel a thing!" Sanji drank the milk against his will for an hour. The Nami above was tapped out for now and was released. Another was in her place, the Gothic Nami from before.
"Yo Sanji," She said. "I guess you found out about our secret and stuff. Oh well. I still like you and all, so hopefully they'll keep you." She hooked onto the machine.
"That food of yours got my tits nice and large," She sneered. "The other girls are jealous!" Sanji screamed for help in a muffled voice, but to no effect. He drank the Gothic Nami's milk until she was tapped out and then switched with another Nami. This continued on until finally, a Nami in a nurse's outfit came and injected a drug into Sanji's penis.
The cup on his penis began to suction. Sanji gritted his teeth, as it increased in size. Eventually he began to ejaculate against his will, but not due to stimulation.
"This is what you will be reduced to: A sperm bank." It was the Scientist Nami. "You were very favorable amongst our society. Even I had a taste for your cooking. But then she had to get close to you…"
Sanji realized who she was talking about. "In any case, you're not going anywhere for a long time." Sanji endured this torture all day. Day by day, he would drink the milk of the Namis and have his penis forced to ejaculate to a semen storage facility, where Namis would go to get artificially inseminated.
Days became weeks, and Sanji was no longer a man, but a husk. A husk, whose only purpose was to consume and produce. His body grew weary and gray, but still had its vigor due to the breast milk and its nutrients. Amongst the Nami Society, there were protests of Sanji's treatment, mainly amongst the ones who had relations with him.
The Scientist Nami came to him one quiet night. "You're still alive," She said. "You are a persistent one. No sunlight, or food for this long. You'll break eventually." She kissed his cheek.
"For what could have been."
As she left, another Nami came to him. Sanji looked at her. "She's…she's…"
This name had blonde hair and a slight curl to her eyebrows.
"It's me, dad. I've grown up," She said.
"I want to live with you and mom. I've brought friends." The Namis from before were all gathered, with Doctor Nami in the center. "We don't have long," She said. "She knows what we were planning. It's only a matter of time before she comes for us. A somewhat toned Nami had the Scientist in her arms, knocked out by a punch.
Sanji looked at his daughter, who was a young teenager due to the hormones at only a month old. She unhooked the suctions off of him and unshackled him. He fell over, weakened.
"First, we need to get him rehabilitated."
