"If someone drinks just one sip of this liquid, the person will receive a specific overpowering fetish!"
"A fetish? Why would you want to give someone a fetish?" Tom asked. He never thought the doctor was interested in sexual matters.
"Well, the main reason is population."
"Population?" Tom asked.
"Yes. It may not be noticeable right now, but my calculations show that within the next fifty years, women will have less and less children. And with that kind of rate, the human race is on a fast track to extinction."
"Why is that? Is there some sort of genetic birth defect?"
"No, no. It's a social defect. Society has become far too moral-based. It needs to reach back to more primitive ways. Only then can the human race be saved. When a man drinks this liquid, he will form a new specific fetish that will drive him over the edge with uncontrollable lust. He won't be able to stop himself from having sex with the first woman he sees."
Tom's eyes went wide. "That's rape!"
"No. It's necessary. If the human race needs to survive, then sacrifices need to be made. And that includes abandoning morality and modesty." The doctor looked at the flask again, then turned back to Tom. "And when a woman drinks this liquid ... well, the same thing happens. She'll form a new specific fetish that will drive her over the edge with uncontrollable lust and won't be able to stop herself from having sex with the first man she sees. And both men and women who drink this will always want to feel that same lust over and over. At first, they may feel a little guilty and regretful about it. But the more they subject themselves to their fetish, the more accepting they will be of their new 'lifestyle'. They'll do almost anything to fulfill their new fetish needs, whatever they may happen to be."
"I can't believe I'm hearing this," Tom said. "That drug is ... is ... horrible."
Dr. Singer scoffed at him. "Oh, don't be such a prude. Believe me. This will do wonders for the world. You just wait and see."
