14 March 1989
Caroline had just gotten up from her bed, and she was in the bathroom, in front of her mirror. He lived in the city of Rio de Janeiro, Brazil, from his birth. A black woman, of medium but sharp and beautiful breasts, had long hair and an enviable ass. Despite this, she did not have many financial conditions and lived with her husband in a small house in one of the poor neighborhoods of the city. Her husband, John, was not very handsome and did not treat her very well. They had married shortly after the same made their 18 and they conceived of their only son, Claudius. Her husband worked as a night watchman at a company in a distant neighborhood, while Caroline lived on small money, working as a maid and cook in several different houses in the southern zone, where the people with the highest purchasing power lived.
Obviously, the salary was not enough, and soon Caroline began looking for new employment opportunities. This opportunity emerged when she was called for an interview at a new company in the city. Its name was "B&C Laboratories", and it was located in a remote neighborhood. Even so, Caroline decides to go to try to change her life and give a better condition for her son and her family.
Upon arriving there, she is impressed by the beauty and cleanliness of the laboratory. It was a white place, with some equipment and computers that, honestly, I never had time to learn how to use. Soon after, a tall, tall woman in office clothes arrives in the room.
- Hello, are you Caroline, our candidate?
- I am. Is this B&C Laboratories?
- Yeah. Please come with me.
Both continue towards one of the smaller rooms of the venue, and soon afterwards, the woman with a high jump begins to explain the company.
- Welcome, Caroline. Our company is a company specialized in the production of medical inputs and operates from Germany. Our specialty has been, for some time, male health, if you understand me. It's complicated. Men would never be more insecure with their sexual abilities declining, and there was a great opportunity for growth in this environment. 
Caroline knew what she was talking about. Her husband was not good at sex, but he did enough to make his wife happy.
- Well, I'm not too pretty to work in a bar or something like that, am I?
- I'm not talking about that kind of male health. Well, let's say there are, inside the human testicles, some substances and proteins that will help us in this research. We can't do that in Germany, because it would be scandalous and much harder to hide, and besides, in Brazil there are people of all appearances, so it will be easier to find more efficient variations of protein. That is the job proposal. We'd like you to collect testicular specimens and bring them to us.
Caroline knew this't be an easy offer. She would have to permanently hurt a lot of people and end her life while betraying her husband, who worked hard to support her with the children. On the other hand, if I did that job, they could change their lives and even get a better place to live. She, after thinking for a few more moments, accepts the request and shakes the interviewer's hand.
"I'm going to give you some items that will help you in your catches," she says as she takes a large bag of needles out of one of the office drawers, "there are some immobilizers inside that you'll use to prepare your victims for surgery. It is of immediate action and should be applied to the neck, and will paralyze for a few minutes everything under the bite, be it arms and legs. It's very useful. After we use them, remove them, we don't want to leave evidence or be tracked. After the male is paralyzed, you go to use this here. It's called elastic alicate. You put it on the top of the bag, and when the blood supply runs out, you just open the bag and cut the two balls out with a knife. Well, just make sure you took the two and brought them to me. Then you will receive your payment. 
Caroline's blood froze. She knew there was no way back now. Only two of those simple balls were worth almost a month's salary, and as she was working on commission, she could make a lot more money, even if it was against his beliefs. She had no way of refusing that job. He took his new valuable work items, looked at them, and then put them in his bag. She took public transport and soon returned to her home, ensuring that her husband did not know about her new job or her goals.
She spent the rest of his day planning what his first attack would be. She thought of looking to buy at the black market and resell, looking at the city harbour or anywhere lonely men think of going when they need help, but the place she decided to go was at the shopping nightclub in his neighborhood. There, she thought she would find young men, carefree with life and not strong enough for her to face. She waited for her husband to go to work, and soon after a few minutes of walking she arrived at the place.
The place was quite large, and there was a large dance court with numerous colorful lights and posters of American singers of that time. “I didn't know their names, but I knew they should be famous”. She began to look at his potential victims, and chose a young white boy who was dancing alone on the dance court, with a typical nerd appearance. It seemed to be his first time at the venue, as did her. She approached him, and with his white smile, captured his attention.
They danced together for a few minutes, making sensual movements, until they both felt comfortable going to a quieter place.
Caroline knew by the boy's nervousness that it was her first time having sex with a woman, and also that it would be her last. They went to one of the nightclub bathrooms and entered one of those cabins, where they soon began to kiss passionately and nervously - he for being their first time and she for being the first time betraying her husband.
She takes off her blouse and shows off her beautiful, steep black breasts, which he quickly begins to touch and suck with a lot of pleasure. He was a little drunk, but that didn't stop him from giving her pleasure in the way a virgin boy could do. She, in turn, was eager to kiss him and feel his penis inside his pants. Without waiting any longer and without the boy seeing, she took the needle and wrapped it in his neck, causing him to fall on it. She threw him to the side, and soon he was stretched and paralyzed on the bathroom floor. The place was pretty filthy, and he seemed not to realize what was about to happen, just laughing and still trying to understand what had just happened and why he was paralyzed.
She approaches him and takes off his pants, putting them next to him and revealing a large volume in his trousers. Soon afterwards, she takes off his pants and reveals a hard brown penis, of large size, similar to that of Caroline's husband, with several veins around and ready to perform the work that awaited him biologically, pulsating strongly while waiting for Caroline's hands. Underneath it, there were two pairs of furry balls, ready to be ripped out and converted into cash for Caroline's family. After a few minutes of thinking, she decides not to perform a last handjob on the man. She was still married, and still had principles. Her husband satisfied her, and there was no need for betrayal. So she decides to focus on his ultimate goal. She takes the man's balls, weighs them and squeezes them a little, trying to feel where she should put the ring and elaster. The man, barking a little because of the drunkard finally seems to realize his fate.
- No... please don't... do you need money? It that what you want?
Caroline couldn't deny that that was what she wanted, but she couldn’t say it. At the first moment she had the opportunity to get up, she knew that guy would kill him and would not give him the money. She thought of keeping his balls intact and letting him go, but she knew she should, after all she had signed up for the job.
She didn't answer. She took the wig and put the rings at the base of his sack. The bags filled with pressure and he trembled a bit of pain, but she knew it would be passing. Then she took a butter knife, not too sharp to hurt his victim, and prepared to make the first incision. She applied a little pressure, which was not enough to cause a cut and break the bag, failing to cut the site. She knew that the paralytic would not take long to lose its effect, and that she should be quick to ensure her own safety. She tried to cut again, while the hon gemmed of pain just moving his head. When she began to notice the spasms in the man's legs, meaning that he would soon recover his movement, she decided to make a decision: use the teeth. He approached the big sack that was now torn and gave him a bite, spitting blood on his whole face. The man screamed of pain, but nobody seemed to hear him.
She felt the thin skin of the place with her teeth, and when she ripped it, she felt a ironish taste of blood, something she wasn't used to doing. She then forced the little hole further with her fingers and opened the bag completely, leaving the two red-white balls on display.
- No! Please! I'm still a virgin!
His penis, which was once upright, had now shrunk with so much pain and humiliation. It was an anticipation of what the future size of his stick would be after that day. She took the butter knife again and tried to cut off the bonds that the first testicle made with the body, while the man was crying, still begging to keep his two small and valuable balls. But Caroline couldn't let her heart soften. It has to be done, and that kid could focus on things that really matter, like studies or family rather than ballads.
The first ball was released from his body and now it was between the fingers of the new castratrix of the city. She felt the man's masculinity with her hands, pressed it to feel the consistency and measured it, putting it soon after in a plastic bag inside her backpack. Then she would put that bag in the freezer until the day he had to return the balls to B&C Laboratories. So they't spoil and she could save on transport by taking them all at once.
Then she held the second testicle, still stuck in his body. She tightened him, played a little with him in his hands and smiled at the man.
- I'm sorry about that. I'm doing this for my family and you won't need these things anymore, you can still adopt children if you want to.
The man started crying. He would never have a girlfriend or a chance to experience sex for the first time, and that's because he decided to venture for the very first time in a ballad. Caroline pulled the little bloody ball forward and pulled; she didn't even need to use the knife. The ball came out of the body and toasted with a bit of the channel that would take her to the penis. At that moment, the man had another spasm and raised one of his legs. That was the red signal for Caroline. She was late, and the man would soon rise up and seek his revenge on her. She put on her clothes again, got up and looked again at the crying face of the man she had just castrated. She left the bathroom cabin, closed the doors, and quickly went out to the exit of the club, with his first pair of balls in his bag and still bleeded hands of testicular blood.
