It was a simple formula used for the companies success, selective breeding using only the best stallions for breeding then culling heavily any inferior stock so ensuring that the males sold at their auctions were of the highest quality and got the highest prices. Nicky enjoyed the work, selecting the best stallions to provide the sperm for the surrogate mothers who themselves were chosen because of their sires and physical attributes. The off spring were then raised until they were ten years of age, Nicky would then select the best fifty percent of the young males for further development, the rejected males were castrated immediately, as they had been castrated pre puberty they could then be sold as eunuchs, prices were good for these young eunuchs as it was popular to have one or two for domestic servants or companions for young daughters. Nicky’s preferred castration method for these young males was elastration, a tight tourniquet was applied to the scrotum ensuring that both the immature testicle’s were strangled, this method was effective and the young males seemed to suffer very little other than a bit of discomfort.

The next cull occurred at sixteen years of age when another twenty percent of the now young colts were rejected and castrated. She would examine each young male closely checking and measuring the length and circumference of their cocks and scrotal sacks, the chiseled form of their bodies and abs, and how pleasant were their features, before selecting those to be castrated. Once the decision was made however she would quickly empty the sacks of these young colts, this was more difficult then castrating the young boys though, for one thing they would now struggle and resist when they were bought to the table and had their legs spread for the knife. Nicky however enjoyed doing these castrations more as it gave her a sense of power cutting open the sacks and removing the now mature testicles from the young man as he struggled on the castrating table, and watching his last cum as he ejaculated even whilst she was cutting out his very manhood. These young males were then sent to auction and sold as gelded colts; the prices were also good for these geldings as they had more muscle mass and could be used for more manual type labour such as gardeners.

The remaining males were kept a further three years and then auctioned as young stallions, they were the pick, with large thick cocks, perfect washboard abs and chiseled bodies, their scrotums were full and heavy. They were purchased by wealthy women who could afford to buy a young stud stallion for her personal pleasure or by a company for the use of the company executives and clients; they could also be bought to be hired out for parties or special events. They attracted the highest prices and Nicky was proud she had achieved sales with above average prices, even setting a record for the highest price ever paid for a young stallion.

She specialized in providing one other class of male, which is what she was doing here today, it was early afternoon and quite warm, the clients had chosen five young stallions they wished to purchase. It had been an exhaustive process each male was minutely studied by the client before they were happy with their choice. The young males were now waiting quietly, secured to a wall by a leg chain, expecting to be taken by their new owners, their bodies were shiny with their sweat from the heat of the sun. Nicky ran her eye over them and was pleased and proud of them, each was a perfect ten, with large cocks now hanging heavy and semi erect in the heat, their perfect bodies chiseled from months in the gym, their sacks hung large and full like bulls between their legs, and Nicky had been pleasured by all five of them, and she could guarantee they would satisfy any women’s needs. They would not have been quite so relaxed she thought if they new what their new owners required, each of them were to be castrated and sold as a gelded stallion. Some women needed a castrated fully mature male to fulfill her fantasies, so she could dominate him and have power over him, and they were prepared to pay handsomely to have one, and Nicky was here to provide them one.

She could not deny it, this was her favorite task every year, there was something about castrating a young stallion that made her moist with anticipation, she ran her eye over the five again and made her choice, she would castrate the one named Tom first. He was nineteen years old with blond hair and a perfect body, Nicky indicated her choice to her five assistants then watched as he was released from the leg chain and secured with a thick leather collar around his neck, it had two leashes one from each side so the young women could control him, he was then led through to where the castration table waited for him. Nicky could see the look of uncertainty in his eyes when he saw the bench with the four leather straps and buckles at its corners, he then began to fight and resist with all his might realizing he was to be gelded, the girls fought hard to get him to table and bend him over it onto his back, they finally got him there only with the use of an electric prodder. The young women finally got the ankle straps on and his wrists secured, they then pulled the ankle straps tight bending his legs at the knees up under the table forcing his legs apart giving Nicky free access to him. She could then easily and freely fondle his heavy young sack, it was soft and pliable and hanging from the warmth of the day perfect for what she was going to do. She quickly made a noose with a piece of soaked leather thong and gently slid it up over his sack then massaged his jewels down to the bottom of the sack, once sure she had them below the noose Nicky jerked the knot as tight as she could, the young man bucked and arched his back as he felt the leather bite into his sack. Feeling his sack going numb he pleaded with her to not do this to him, “Please don’t cut me” he pleaded, “please don’t cut my nuts out”, it has to be done Nicky told him gently, “I will try to do you as quick as I can, just hold still for a few minutes and I will soon have em out and make you two stone lighter” she cooed. It had only been a few seconds since she had noosed his nuts and already his large heavy cock had began to swell and rise, Nicky gently started to stroke his cock until it was a ten inch rock hard bar, she had noticed long ago that young stallions always got an erection when they were to be castrated, she did not know why, it was like they wanted to be gelded, even when she was cutting through the cords to their big nuts they were hard and would cum and cum.

As she gently stroked his big hard cock Nicky thought back to three years ago when she had ridden this young stallion for the first time and broken him in. He had been a sixteen year old colt with a V shaped chest and muscular shoulders and ribbed stomach muscles at the time, when he had come to her room he had stood nervously in front of her with only a loin cloth on, she had told him to remove it, which he did and had stood there totally naked in front of her, she had caressed his chest and lightly kissed and sucked his nipple, then she run her hand down over his hard rippled abs until she was fondling his now rock hard cock, it was huge for such a young male. Nicky pushed him back onto her bed and started to lick the big purple head of his circumcised cock, she could taste the saltiness of his precum as she slowly sucked his big young cock into her mouth, as she started to bob up and down on him he started to moan and thrust his cock into her mouth. Nicky all the time was fondling his nuts in their big smooth sack, and sucking harder and bobbing her head up and down faster until the young man grunted and with one last thrust had shot a huge load of cum into her mouth, she had sucked and savoured every last drop of his sweet young cum.

That had been three years ago he was now laying spread eagled and strapped onto a castration table, he was moaning again now but not with pleasure, Nicky gave his big smooth sack a last fondle and felt his big kiwi fruit sized nuts once again, they were in truth now only waiting for the knife. Looking at her assistants Nicky knew it was time to cut him, they were as excited as she was with their nipples hard and showing through the cloth, yes it always excited young women to see a young well hung stallion gelded. She picked up a small razor sharp knife specially designed to cut open just such a sack as was between this young mans thighs, “are you ready” she said to him as she held his fat bunched scrotum, “No please don’t, I don’t want to be gelded” he pleaded, “I guess your as ready as you ever will be” she said to him, “here bite on this” she said as she placed a thick strip of leather between his teeth. Then pulling on him Nicky cut the bottom out of his sack with a single swipe of the blade, he bucked and arched his back kicking and struggling to break free and away from the knife between his legs, “well he didn’t like that much” one of the younger girls said with a nervous giggle, “he will like this less” said Nicky as she gripped one of his big nuts between her thumb and the back of the knife blade, she pulled until she had six inches of his nut cord out then started to scraped the sharpened edge of the blade through the thick cord. The young man grunted and a spasm shook him as his big ten inch cock erupted shooting white cum in great jets all over his chest and ribbed stomach, he continued to shudder as Nicky dropped his big blue grey nut still quivering into the bowl waiting for it, she quickly stripped his other nut out of his sack and repeated the scraping process on his remaining cord, he grunted once more as it came away and shot his last ever cum, then fell back moaning, no longer a heavy sacked stallion but now a young gelding created to satisfy a wealthy women’s whim, as he rolled his head over to one side he could see his two big nuts in the bowl where Nicky had placed them. She patted him on the head as he was been released and said, “you did very well it wasn’t so bad was it, you had a nice big set in your bag but you are better off having them out”.

Nicky then went to decide which one of the other four heavy sacks would be the next to feel the stinging kiss of her knife.
