I tried to scream out in terror, but couldn’t make a sound. I could make no vocal sounds, only whispers. The rest of the changes were done: I could feel my new muscles, my new smooth skin, even my new perfect teeth. I clenched my ass, which was very tight indeed: at least that was still attached.

Mr. R—was at my side, holding my hand in his. Mr. M--- was there too. “You look great,” He said, “all of the changes are done now.” I gave him a worried, confused look. “Of course, we don’t tell you everything that would change, or you might try to back out.”

“You have been asleep for two weeks, so the physical transformation is complete. There are two changes that you have noticed. Your voice will return: do not be concerned. This is an unavoidable side-effect of the transformation. Usually, this lasts for no more than a couple of days.

“The more important change is the removal of your genitals.” He held a mirror to my crotch, revealing a smooth expanse of skin above a tiny hole between my legs. “You will urinate through that tiny piss slit,” Mr. M--- said matter-of-factly.

“There is more to the story of San Miguel,” Mr. M--- said. “In order for the changes to be permanent, it is unfortunately required that your genitals be removed. The hormones made by your testes are incompatible with the transformation process for a bottom. On the other hand, your penis has magical powers for your chosen top. Shortly after they were removed, Mr. R--- consumed your genitals, which made his modifications permanent and irrevocable and which also bound the two of you together at an organic level. So you see, your genitals help make your top: you really are a part of each other now.

“You must understand that your modifications, however, are not permanent and require Mr. R--- to continue your therapy. First, Mr. R--- must bring you to our office for maintenance therapies. Second, you both must stay on the island at least 180 days each year, because the island geology has special properties that make it all possible. Finally, your body must absorb Mr. R—‘s semen at least every other day. Of course, more than that is perfectly acceptable. The semen can be absorbed through your mouth or rectum. If circumstances will keep you apart for more than 48 hours, Mr. R--- must store additional semen for you to consume while he is away.

“Our counselors will help you with all of this, of course. I think every bottom feels a loss for a short time, but soon understands that all of the sacrifices are worth it. And, in any case, as a bottom, you can focus completely on your service to Mr. R--- without being distracted by your own genitals.”

I suppose I should have been sad, but I really wasn’t. The mirror also revealed the stunning new body that I was a part of. I was a hot bottom now, there was no question about it, and I was about to be controlled by a very hot top.

“I will release your bindings, if you promise to be good,” Mr. R---- said. I nodded silently.

He unlocked me, and I rose slowly to a sitting position. I wobbled when helped to my feet. “You will have to stay here for two more weeks,” He said, “but I will be with you. Then you will come home with me.” He led me out of the room--still naked--and down a series of hallways. He opened a door to what looked like a well-furnished hotel room.

I began to feel energized as I entered the room. I had a great new body and would get to live with the most beautiful man I could imagine.

He laid me down on my back on the bed and was instantly on top of me. He held my face with both hands and began kissing me. I kissed back and pulled him tight against me, feeling his muscled form against mine for the first time. He rose and pulled off his clothes, revealing his smooth brown body and perfect hard cock. He stood at the end of the bed. “You want to suck me more than almost anything, isn’t that right?” He said.

“Yes, it is,” I replied.

“Kneel,” He said. His cock was instantly in my mouth and throat. I don’t think I had ever sucked such a large penis before, but found I had no problem swallowing it whole. It was as if my throat had been specially constructed to fit him. He purred softly as I sucked.

After several minutes, he pushed my head back and pulled himself from my mouth. He shoved me back onto the bed, and kneeling between my legs, pushed my knees back to my shoulders. With my anus exposed, he touched it with the tip of his moist penis. I wanted him: wanted him inside me more than I had ever wanted anything.

From the night table, he grabbed a tube of lube and spread some on his penis and my hole, stopping to slide his thick index finger into me. I was very tight. “Open up for me, boy,” He said as he began to penetrate me with his penis. I expected it to be painful, but it wasn’t; my anatomy really had been perfectly sized just for him. I held his big shoulders as he fucked me, content for the first time in my life to concentrate completely on the man fucking me. As he got closer, he stopped and looked in my eyes.

“We will be happy together,” He said, holding his massive body against mine and barely moving his penis inside me. I nodded at him, moaned in yearning for the release only he could give, clasped my anus tightly and rolled my eyes back in pleasure. He moved almost imperceptibly against me and growled. “I’m cumming inside you,” He exhaled, pushed himself deeply into me and held my hips tightly against his.

I felt his semen flowing inside me only a split second before a convulsing wave of ecstasy washed through my body. I gasped, spread my legs wider, arched my back to meet his thrust and clawed against his wide shoulders. I felt his pubic hair against the smoothness of my groin, reminding me of his manhood and the absence of mine. He collapsed on top of me and gently kissed my neck. Still inside me with my legs high in the air, his hands caressed my hips and buttocks.

“You must not lose a drop of my cum,” He said, “be very tight and very still.” He withdrew and laid down beside me. I clasped his precious semen inside me. I leaned across him, licked his penis clean, and sucked the last few drops of semen out of his deflating penis, all the while keeping my hole tightly clenched. He had given me a monster load, I was certain.

I laid next to him, my face on his broad chest, feeling his semen swimming inside me. “I saved that up for you, so I cannot promise that there will be as much every time,” He said sweetly. I looked closely at his soft penis for the first time and squirmed down so that the head could be in my mouth again. “Be careful in that position,” He announced, “I will have to piss soon.”

He pulled me to his face and kissed me softly on the lips. His lubed finger found my hole and slid into the loose channel. “Yes, you are full of my semen. It will keep you strong, you will see.” He swirled around inside me, rubbing his cum against the wall of my rectum. His finger slid out of my anus and touched my piss slit. “I am sorry you had to lose them, but unfortunately it was part of the program.” He continued touching the new hole, slowing pushing a finger into it. “I’m told that this little hole can be stretched, even fucked. We will have to see if that is possible. For now, there are enough ways to enjoy you.”

“What did it taste like, my penis?” I asked.

“It was not very tasty, I will admit, but it is important. I was made stronger and my body shape is now permanent. It was magical.”

He began to rise. “Please kneel by the bed.” He stood in front of me and placed his penis in my mouth. “I would like to urinate,” He said, “do not lose a single drop. Let it flow into you.”

And so began my life of service. The next two weeks flew by. He was always at my side. He took me to the gym, took me to physical therapy and assisted my counselor. The Service had contacted my employer, cleaned out my old apartment, and moved the few things of value to St Michael. I had no second thoughts and the sex continued almost non-stop.

With the help of my counselor, I learned to forget about the genitals I once had. I sat or squatted to urinate, just like a girl. When he was fucking me, I concentrated completely on the feeling of fullness, the completeness that his penis gave me. In truth, I loved the way he filled me, loved that I could help to bring him pleasure. And when he came, I came too—not in the same way, obviously--but an orgasm just the same.

We moved to his “villa”: a beautiful mansion on the beach. He trained me to care for the house while his days were spent in his large home office. It was never clear to me what he did, other than talk on the phone in Spanish and make a lot of money.

A couple of months later, the sex began trailing off to less than once a day. Mr. R. announced it was time to visit the Service for a therapy session.

Again I was laid upon a table and put to sleep. When I awoke, my body had changed again. I was stood before a mirror to reveal that I was no longer a body builder, but was now thin and lean. My skin was darker. My face was hairless and thin while the straight, long and dark hair on my head had been gathered into a pony tail. Thin wisps of dark-colored hair clung to the lean legs that had once been muscular and completely smooth. Of course, I still had only a tiny piss slit where a cock and balls had once been.

“I saw a boy with a body like yours and it really got me fired up,” Mr. R—explained when we returned home. He was on top of me with my legs in the air almost at once. This time, his penis didn’t fit so perfectly; it was painful to be fucked, especially when he pushed himself all the way in. He wanted to fuck me from behind, which he had almost never wanted to do before. I got on my new, bony hands and knees while he kneeled and penetrated me. I had less control in this position and could relax less. He grabbed my pony tail, and with the extra leverage, pounded my thin ass. I felt like I was being split apart. When he finally blasted inside me, it was more of a relief to me than a pleasure, but it was clear that he had enjoyed it.

Once again, he fucked me almost non-stop. He started fingering my very loose hole after fucking me, spreading his juice around inside. Eventually his whole hand found the inside of my hole, too. He had never fisted me before, but now wanted to “see how far he could get.” I moaned in agony and ecstasy as his thick forearm would push inside me.

More slowly this time, the sex began to tail off and then I was back at the Service for a therapy session. My body was transformed again, this time to a big-lipped African boy that he wanted to have suck him non-stop. When Mr. R-- was tired of him, I was transformed again into a smooth, bubble-butt Asian boy. He loved laying me down flat on my belly, climbing on top of me, and fucking me from behind while he held my wrists above my head. In truth, I loved that too.

When he tired of me, he’d bring me in to the Service. My skin changed from white to black and everywhere in between. I was a jock one month, a bookworm the next. I was a wrestler and a footballer and an altar boy. My body was hairy sometimes, completely smooth others. I was thick and muscular and thin and waif-like. Some of the forms, including the first bodybuilder, returned more than once. Sometimes I would be transformed for only a few days before he changed his mind, sometimes he stayed with a form for many months. There was only one him but many of me.

We stayed on St. Michael almost all of the time. On the rare occasions when Mr. R--- had to travel off the island without me, he would save vials of his semen, which I would inject into my rectum every two days.

One day, years later, Mr. R—and I were lying on the main beach in St. Michael. As he read a magazine, his perfect, always beautiful body glistened in the sun. At the time, he had given me the form of a youthful Latin soccer player with thick, hairy legs, a thin torso and six-pack abs. I lied on my belly, my back to the sun, and propped my head up so I could watch the parade of people on the beach. My tiny bikini swimsuit accentuated my thick butt, and lying on my belly, no one could tell that the front of the suit was completely empty.

There were many members of the Service scattered about the beach. They were easy to spot: muscular top men with a mostly youngish looking boys trailing behind. Several of our friends waved at Mr. R—and me, and I waved back.

And then I spotted Robert, my old friend! He was older now: much, much older. He walked alone along the waterline in the slow, plodding gait of a senior citizen. Clearly, he had never become a member of the Service. I rose to run after him before realizing that he would never recognize me. I watched him slowly walk down the beach before he disappeared into the crowd. I reached down and rubbed my smooth crotch and tiny piss slit. As my leg touched Mr. R—beside me, I clenched my hole tightly and felt his semen still inside me. What a lucky boy I was.
