Being a single father of three sons was a task all right. Their mother had walked out on us shortly after the youngest was born. She knew better than to fight for custody; there was no way I would ever give up my sons to her. Nor did she make any effort to stay in their lives, which was just as well. She would not have understood what I had planned for them.
As a doctor of endocrinology, I had the knowledge and the wherewithal to see to it that my boys didn't suffer the same agonizing adolescence as I did. I was a beanpole in my youth; six feet three inches and 150 pounds of wimp. As such, I was a target for every stud in school, always the laughing stock, always the punching bag. I had used my knowledge to develop myself into a hot two hundred twenty five pounds of beef as an adult, but the scars of my youth were still with me. That wasn't going to happen to my boys!
When my oldest, Tony, was nine, I started him on a program of injections that started his adolescence early. He also started to lift, under my supervision, and began a program of jelquing and vacuum pumping of his penis. He was a naturally big boy; masculine, assertive; so he took to this regimen like a duck to water. By the time he was twelve, he was five feet tall and 200 pounds of powerful boy-flesh. His balls were twice the size of an unenhanced man, and his penis was a proud nine inches.
It was time to take him to the next level, which meant short cycles of fast-acting roids, in combination with HCG, Clomid, and other things to keep his own hormone production unaffected. This could have stopped his vertical growth, so I was going to add HGH to the mix, which would also improve his tendon and ligament strength, make his bone structure more massive, and keep his penis growing as well. By the time he graduate high school, I fully expected Tony to be the most amazing specimen of manhood the world had ever seen.
There was just one problem. Tony's sex drive was already very strong, and I could only imagine what it would become once I put him on these new substances. Girls were already flocking around like bees to honey, and it was only a matter of time before he knocked one of them up. I had talked to him about the importance of protection, but it was unrealistic to think he would always be so in control of his desires as to think of that. He needed a steady sexual outlet, something beyond mere masturbation, but with no risk of pregnancy. I wasn't going to have his life ruined by some stupid slut who was looking for a meal ticket.
My next boy, Mickey, was now nine. He was as different from Tony as could be: shy, sweet, sensitive. He was just as good-looking, but in a much more delicate way. In looking at him, it was hard for me to imagine what he would become if I put him through the same treatment. He would certainly never be Tony's equal in size or strength, and he would never have the same cocky self-confidence. It seemed cruel to put him in a position where he would always be compared, and found wanting.
The answer to my dilemma came to me one day when I walked into Mickey's room and found him admiring himself in the mirror, almost naked. That was nothing unexpected in a boy, but what clothing he was wearing was: a bra and panties! Apparently he had salvaged them from a bag of stuff his mother left behind. The truth about Mickey came to me in a flash: he wasn't a boy at all! Not inside. Where it counted, he was a girl!
I carefully slipped out of his room, and went to my office to think this through. Mickey was a girly-boy. Tony needed a mate. Mickey could never become a stud like Tony. There was only one thing to do. I went back to Mickey's room, and rapped on the door, asking him to join me in my office. It was a few minutes before he did; no doubt he was hurriedly getting back into his boy clothes. When he got there, I told him it was time for him to start a series of treatments like his brother did at his age. He asked me what they would do, and I told him they would make him more of what he already was: a better version of himself. This seemed to satisfy him, and I gave him his first shot of estrogen, and a bottle of pills to take four times a day.
I also did an exam, and realized how foolish I had been not to realize Mickey was really a Michelle. His tiny penis was no bigger than an engorged clitoris; his testicles were no bigger than two marbles. His muscles were those of a little girl, and his bottom had a natural roundness, a fullness that bespoke femininity. He would be so much happier as a girl!
Tony's progress over the next year was remarkable. By his thirteenth birthday, he was five foot three inches tall and weighed two hundred and 225 pounds. He was already my weight, though a foot shorter! His penis had lengthened to ten and a half inches, and his balls were the size of AA eggs. His pubic hair was a dense black bush, and his pits were filled with the same fur. His legs had a light coating, and there was a patch between his thick pectorals. He had to shave every day. He wanted to grow a beard, but I felt this would elicit too much comment; there were enough extraordinary things about Tony without adding that!
His sex drive was keeping pace, and he seemed to have a perpetual erection. He was allowed to wear sweat pants without underwear around the house, as he was very uncomfortable otherwise, but I made him wear a jock elsewhere, to strap his huge organ down. I was getting more and more anxious about his sex life, and so I decided to take some action.
Mickey was rapidly developing as well. He now had a lovely pair of B cup breasts, and his ass was round and full. He was getting more emotional and sensitive, and no longer even pretended to be interested in boy things. I called both boys into my office and began to explain the situation.
"Boys, you know that I am using my skills to help you both become more and more of wht you were born to be; to excel, and be extraordinary, so no one will ever pick on you the way they did me. You will be looked up to, admired; natural leaders."
"Aw, yeah, Dad, I know, and it's so cool!" Tony enthused. "I love what a stud I'm becoming! You're the best Dad ever!"
"Thank you, son; I'm very proud of you. How about you, Mickey? How do you feel about all this?" Mickey looked up at me shyly, his face full of confusion.
"Well...I don't really understand, Dad. I mean...I'm not getting anything like Tony. He gets bigger and stronger and more handsome every day..." and with this, he gave his brother a look of such longing, I knew my task would be simple. "...while I seem to be as weak and small as ever."
"Let me ask you, this, sweetheart: are you happy the way you are?"
"Well...yes; I am. But I want you to be proud of me, the way you are of Tony. I don't want to fail you." And he began to cry softly.
"Oh baby, come here; sit on Daddy's lap." He did.
"Now listen to me carefully: I said I was helping you to become more of what you are meant to be. Do you think that what is right for Tony would be right for you? Can you see yourself as a big muscleman, with a huge cock?"
Despite his tears, Mickey giggled at that. "No; that would be silly!" Tony laughed deeply at the idea as well.
"Mickey, do you want to tell us what you do when you are alone in your room?"
Mickey flushed, and stammered: "Oh Daddy...how do you know about that?"
"Because I walked in on you one day by accident. Tell Tony what you do."
My boys knew better than to ever disobey me, so Mickey quietly said: "I dress up in girl's clothes." Tony's mouth dropped open in amazement.
"No shit? Why would you do that?" Mickey went silent.
"Tell him, baby. Why do you like the feel of silky things against your skin? Why do you like to see yourself in a bra an panties?"
With a great effort, Mickey finally spoke: "Because...I feel more like a girl than a boy."
"Fuck..." breathed Tony. Normally I wouldn't have allowed that kind of language, but under the circumstances I let it pass.
"That's right, Tony," I said. "Turns out you have a little sister instead of a brother. How do you feel about that?"
I glanced at Tony's pants, and his dong was at full salute.
"Could I...could I see?" he said.
"What do you mean, Tony? You want to see your little sister in her girly clothes?"
"Yeah; would ya do that Mickey? Show me?"
"Michelle, Tony" I corrected him. "Her name is Michelle now."
Michelle said: "I would, but I only have the bra and panties."
"Not any more, baby girl" I said, bringing a bag from under my desk. Michelle opened it with delight.
"Oh, Daddy! They are lovely!"
"Go put them on, honey, and let us see how you look." Michelle rushed from the room. I was left with Tony.
"Well, son; what do you think?" Tony looked very uncomfortable.
"Uh...I dunno what to think, Dad. All of a sudden my bro is a girl! I mean...jeez!"
"I know it's a big change for you, but I need you to be strong for Michelle. She's your little sister, and she will need your support and protection."
"Oh jeez Dad, you don't hafta worry about that! If anybody messes with her, I'll take 'em out!"
I smiled to myself; he was already thinking of Michelle as "her."
That's good, son. I think it would be best if Michelle was home-schooled from now on. It would be pretty hard to explain how she became a girl all of a sudden."
"No shit!"
"Tony...language."
"Oh, sorry Dad."
"There's something else, son. Have you noticed the way Michelle looks at you sometimes? Especially when you have your shirt off, or when your big boner is bouncing around, like now?" Tony flushed. "No reason to be embarrassed, son. I wouldn't have given you a huge cock and big muscles if I didn't want you to be proud of them. I'm just saying...Michelle is a girl, a girl going through puberty, and it is only natural that she would be attracted to you."
"But Dad...she's my sister! That would be incest."
"Well, yes...and no. She is your sister, yes, and has a kind of pussy. But she doesn't have female reproductive organs, so you could never get her pregnant. The incest taboo is all about preventing retardation. That isn't an issue here."
"Dad, you mean...you want me to..."
"Fuck her? Yes, son. I do." I saw no point in beating around the bush.
Tony's jaw was on his chest, but his dick was about to burst through his pants.
"You need a mate, son; one you can't knock up. I won't have you wasting all your potential by getting some slut pregnant. Michelle is a perfect solution to you problem. Further, she is a horny little girl; she needs it as badly as you do. Do you really think she can be around a stud like you all the time, without getting any satisfaction from you? It would be cruel."
I could see Tony's mind racing. Before he could respond, Michelle entered and delivered the coup de grace.
"Well...how do I look?" She was in the cutest little dress; it draped itself over her pubescent curves like a second skin, clinging to her nubile young breasts and her perfect peach of a bottom. Even I was stunned by her sex appeal, and was dealing with a major hard-on myself. Tony struggled to find words.
"Aw, sis...sis! You're...incredible!" Michelle gleamed.
"Oh, thank you, Tony! I'm so glad you like it! And thank you, Daddy!" She ran to me and threw her little arms around my neck, kissing me on the cheek. "You've made me so happy!"
"Uh...what about me?" Tony rumbled hoarsely. "Don't I get a kiss?" Michelle blushed and went to Tony. They stared at each other; the sexual tension was so thick you could have cut it with a knife. Suddenly his self-control broke, and he grabbed her, pulling her to him, and planted a big wet one on her pink lips. Instinctively, she threw her arms around his neck and I heard a small moan escape from here throat.
"Ahem," I interrupted. They broke apart. "I need to speak to Michelle alone now, Tony. Please wait for me in your room." He stood and walked out, doing his best to hide the massive bulge at his crotch.
For the next hour, I explained the facts of life to Michelle. How things were between a man and a woman. What her role would be, what would be expected of her, in bed an elsewhere. I also told her that I understood she was in love with Tony, and I approved. I explained about his enhanced sex drive, and that she couldn't expect him to be able to resist her charms, that she had to take responsibility for his needs. I showed her how to do that, both anally and orally. No, I didn't have sex with my daughter, but I demonstrated how it would happen. I taught her how to douche, and that she should go to Tony's bedroom door later that night, to mate with him. Michelle accepted all this with alacrity and eagerness. How rightly I had judged her! She would be a perfect mate for my strong bull of a son. Then I sent her to her room to prepare herself for her deflowering.
In Tony's room, I found a stallion in heat! He was pacing the floor, his massive dong leading the way. I told him he could take his pants off if they were uncomfortable. He did, and I had to gasp at his magnificence. He was masculine potency personified.
I explained to Tony that I had created Michelle just for him; that he needed a very special mate, and Michelle was anxious to be just that. I explained that she was every inch a woman, and needed him to be dominant, to take control, to be her man in every way. I also told him that I expected him to be faithful to her; that was the condition of this gift I was giving him. He agreed to all that, though he was so horny, I think he would have agreed to jump into a vat of boiling oil if it meant getting some pussy! But I knew my boy would never break his word to me.
I also told him that he needed to be careful taking Michelle's cherry, that he was extraordinarily big, and she was a virgin. He seemed to calm down then, and a tender look came over his face.
"I'd never hurt her, Dad. She's so soft, so pretty..." I realized then that my worries were over; my boy was in love.
A soft knocking at the door caused his great organ to jump with excitement. "You'd better get under the covers, son; you don't want to scare her away with that thing!" Tony complied. I opened the door, and there was my little girl, in the pretty pink nighty I had bought for her. I leaned over and gave her a little kiss.
"You're man is waiting for you, sugar. When I see you tomorrow you will be a woman." I escorted her to the bed, and left them alone. As I exited the room, I heard a gasp from Michelle: "Oh, Tony!"
The next morning, I was reading my paper at the breakfast table, when Tony came sauntering in, naked as the day he was born. He had that look of smug satisfaction that all studs have after a night of deeply satisfying sex. He scratched his balls, and smiled at me.
"Happy, son?"
"Aw, Dad; Michelle is so incredible. I love her so much! Thank you for...well, everything." I held my arms out to him, and squeezed his hard bulk.
"My pleasure, son." As he pulled away, he noticed my own erection straining through my robe. He laughed.
"Jeez, Dad, we need to get you a woman too!" "We sure as hell do, " I thought. Just then my youngest, Jody, came bouncing into the room, in the pink pajamas he seemed to favor. His eyes locked onto my boner, and he unconsciously licked his lips. Tony missed none of this.
"Maybe you won't have to look too far!" he smirked.
