Koyori was an accomplished chemist
Despite this, she wasn't really an official one
She may have not had some of the standards or qualifications of other chemists, but she still knew quite a lot
In a way her unofficial status had led her to greatness
She lived off of private siphons that the Japanese government supplied her
She could supply them with the wonderful things she had discovered and invented, some of which could lead to massive breakthroughs
Her latest study was just this, it could possibly allow parents to detect and choose the best offspring
She always had a special interest in microscopic life, the fact that life could exist in such tiny form astounded her
This interest meant she would approach her task by first studying the sperm, something she had been eager to look more into for a while
Because of her prestige, she got many male volunteers
To ensure the sample was of fine quality, she'd help harvest it
she'd have the male subject take off his pants and underwear before sitting of a bench in a sterilized room
she'd then crouch down in front of their lap, positioning the collection vessel in the right place
she'd go on to wrap her hand around the male subject's penis before stroking it to ejaculation
To help speed up the process, she'd where her lab coat loosely, she also wore nothing underneath it
She also didn't where any gloves for this procedure, she insisted that it helped perfect the sample
This was all very unprofessional though if she really needed to, she wasn't above abducting more subjects
She brought her new samples back to a machine she had built and patented
It would study a sample and best try to describe its traits
However, Koyori had built extra functionality into the machine that only she knew how to access
You see, ever since she had shirako at 12, Koyori craved the stuff
She had an unhealthy addiction
After messing with part of the machine, it gave new readings
Some of which included tasted, consistency, and texture
She almost fainted when she read the latest sample's reading
It sounded perfect, a pool formed under her as her panties dripped from her wetness
She immediately grabbed the petri dish and dumped it into her mouth
It tasted so good, she swore she could feel each sperm swimming around, touching her tastebuds in just the right way
She needed more and began gobbling more of the sample
She didn't want to run out of this so she conserved it while running a small amount under a machine that could possibly multiply substances
She began to mix it with other substances to try to create an enhanced version
This is where things would change
She had just mixed the sperm with a deep red substance and took a sip
Suddenly she fell back
She felt something in her panties
She held them open to look inside
"F-futanari?"
She had miraculously grown a penis
She had no time though as she'd have visitors coming
The two visitors were Chloe and Lui
As Lui walked past her, Koyori turned her view to look at Lui's ass in her tight leather bottoms
No man or woman couldn't help but stare
Koyori normally would only be slightly aroused
This time however, her new penis helped contribute
It got so bad that she ordered the other two out of her lab
All she could think of was Lui's ass
She began to masturbste her new penis
She could feel it coming so she hunched up in a ball where her penis was as close to her face as possible
She then came, some of her cum shooting out onto her face
She quickly scooped up the rest of it into her mouth before licking her lips
This was now the best thing she had ever tasted
