DNAmy's Futa Gene

DNAmy smiled as she stared at the completed and fully tested Serum, enough of it made to fully infect the entire worlds water supply with no way of removing it after all it wasn't a harmful serum. DNAmy was aware of the futanari gender sometimes called hermaphrodite. There were some animals that had this gene, slugs, and frogs to name a few. Technically the gene was in humans but due to the dominance of a male and female gender it could not come out... till now. This serum would be drunk and if a person had the futa gene in them they would become one. Size of the drinker would vary based on various genetic, emotional and even mental factors. She smirked as she released her specially designed insects into the serum to infect the worlds water supply, who would become a true futanari? The first of a new gender... of a new race of humanity?
