Dr. X was beside himself with anger. With the team-up of the X-men and the Brotherhood of Evil Mutants working to avenge the castrations of their fellow mutants, and the infiltration of Dr. X's secret government compound, the boy Leech had been stolen back for the good of mutant kind.

To make matters worse, the mutants they had spent so much time capturing were sprang loose from their prison cells and set loose back into society.

Well, most of them anyway.

There were a few that were not discovered. Captain Garret when being interrogated by the Mutants Wolverine and Magneto on a nearby catwalk, during the invasion, gave faulty directions to the hiding places of certain mutants throughout the compound. Some of Dr. X's most coveted mutants, who were indeed on the premises, were said to be detained in government facilities in other parts of the country and beyond.

Garet knew that Dr. X would never forgive him if he gave the locations of those particular mutants, and met a compromise with freeing those who Dr. X deemed expendable.

Of course, when Dr. X said expendable, he meant "un-fuckable."

So when the dust was cleared and casualties of staff and soldiers was accounted, repairs to the compound were being made, and all real mutant threats had left to free their brothers in said government facilities in other parts of the country and beyond; Dr. X took a shower and put on a robe, ate a decent small supper, and went to his lab to do what he loved to do the most.

He crossed his legs and sat in his wheeled office chair, looking over his papers. He got on the intercom and summoned the Captain.

"Captain Garret went on a much needed stress leave sir. He should be back by the end of the month." the voice on the intercom said. "But I'll be his replacement for the time being. I'm Captain Reece."

"Reese," Dr. X said, running his fingers through his light brown hair. "Give me some good news. How many of my top ten do you still have in detention?"

There was a pause as Reece looked on his updated computer screen. There was some clicking sounds of keys being pushed over the intercom.

"Uh, four sir," Reece sounded hesitant to report.

"Wonderful," Dr. X said sarcastically.

He paused with awkward silence.

"Sir?" Reece asked, wondering if the good Doctor had terminated their line of communication.

"Do you have anyone big Reece?" Dr. X asked.

"Sir?" Reece asked again. This time he had no idea what the Doctor was talking about.

"I'm feeling a little blue with this whole invasion...." Dr. X said, sounding depressed.

Reece listened intently.

"....and losing all the mutants...." Dr. X moped, his head drooped into his arm as he spoke, making him sound muffled.

Reece continued to listen with difficulty as Dr. X continued. "...and I just want someone big, that I can, you know, dominate over." he concluded.

Reece was relieved Dr. X didn't want someone of teen years. They had all been saved during the infiltration.

"Of course sir," Reece declared pleasantly, "we still have Piotr Rasputin, or as we like to call him, 9054."

"Who?" Dr. X hadn't heard of him, but an image of the crazy monk from the Russian Revolution of the early 1900's filled his mind. He didn't want some nasty fool with chicken bones in his beard.

"Well the media called him Colossus, sir," Reece said.

Instantly Dr. X's imagination was filled with the image of sleek metal skin, shiny and bulging. He was well aware of Colossus. He had been saving him for a rainy day.

"Perfect," Dr. X smiled, his mood was lifting instantly. "Perfect, perfect. Could you have the men wheel him up here as soon as possible? I believe I will be working late tonight."

"Yes sir." Reece complied.

With twenty minutes, Dr. X had the young Russian splayed across his X-shaped table completely naked. His hands and feet were bound with straps that could not be broken, as had other mutants who met their fate on this same table. Piotr had been drugged but soon he was awake and groggy.

"Hello Babbamabushka," Dr. X's Russian was obscenely inelegant. He ran his fingers down the left pectoral muscle of the young man. His muscles were taught with years of exercise and just being a large man, but the skin covering the muscle was smooth and clean. Dr. X couldn't help it. He bent over and kissed the X-man's skin, running his tongue over the nipple.

Besides the thick black hair on the young man's head, and of course the black pubic hair which he kept trim, Piotr's body was virtually hairless. His abs were a perfect six pack below his bulging chest. Dr. X had abandoned his clip board for taking measurements and simply filmed everything with a hand held digital camera. He ran his hands over the arms and legs, the massive muscular thighs, down the abdomen. Dr. X' put down the camera and his green eyes met with Piotr's eyes. Dr. X adjusted his glasses.

His mood was foul only two hours earlier and he wanted every mutant on the face of the Earth to be burnt to ashes. But seeing this strong young mutant powerless on his table changed everything and his mind could only think wicked thoughts of lust.

"Is there anything I can do for you before I castrate you?" He ran his fingers up the inside of Piotr's thigh and brushed the tips over his asshole. Piotr tried to tense up but the alignment of the table left him involuntarily exposed to Dr. X's machinations. Dr. X stuck his tongue out and licked the tip of his index finger. He brought it to Piotr's asshole and started to rub his anus in circular motions. At the same time he brought his lips to the young Russian's mouth and kissed him deeply. Piotr was not in agreement. The mention of his potential castration left him in a panic and full of rage. He tried to bite Dr. X on the lips feverishly, but the good doctor pulled away just in time.

"Dog!" Piotr sneered. "I do not engage in such acts of perversion! Try that again if you dare, and I will take your jaw along with your cursed lips!" He bared his teeth to expand on his threat.

Dr. X produced an electric cattle prod from beside the table and turned it on. With a face void of emotion, he zapped Piotr on the cheek, across the eyelid, on the nipple, under the ball sack, and finally into the anus. The thick Russian squirmed and pulled against his restraints, but to no avail. He took each electric charge with a scream of pain with his eyes shut. He had the stamina of a wild bull. It would take much more to break him than any petty device sitting around in Dr. X's lab.

Dr. X decided to blindfold the young Russian. To insure his privacy, he went to the control panel and darkened the tint of all the windows that allowed anyone outside the room to see what he was doing. His regular lackeys knew when they saw the windows tinted from the outside that Dr. X was not to be disturbed. But just to be on the safe side, he incorporated the assistance of the hydraulic locks.

He approached Piotr again and this time removed his robe. He was stark naked underneath and the lights that shown from above highlighted his own perfect wiry body to statuesque proportions. He brought out a standing mirror and compared the size of his own naked body to the size of the Russian's. He was considerably smaller, but that was fine. He took his glasses off and set them on a side table. With that he went straight for Piotr's genitals. His favorite part. Although he marveled at the perfect curvature of Piotr's muscular system, he wanted the cock more than anything. He picked it up in his hand. It dwarfed him. It was seriously 10-11 inches flaccid. A marvelous specimen. He had a time inserting just the cock head into his mouth. But as he got used to the handling he found that sucking off the big Russian was not only manageable, but quickly became enjoyable. He wondered what such an immense cock would feel like penetrating him.

Normally Dr. X considered himself a top. That was a given. He was going to fuck the Russian mutant in the ass before the night was over. There was no other alternative. But tonight, Dr. X found he felt empty. He wanted a change, he wanted something that felt extreme. He wanted to unwrap the lube he got as a Christmas present from his ex-boyfriend last month.

He lifted the balls. They were warm and soft, and huge. Positively the size of tennis balls. But Piotr himself was not small, he was of giant stature. Having tennis ball sized testicles was par for the course when you were the size of a mack truck. Dr. X tried to get one of the balls in his mouth and gave a squeak of delight when they would not fit. Instead he bit into the ball like it was a nectarine. He did not break the skin, but left angry red marks where his teeth had been. Piotr cried out in pain and began to break out in a sweat.

"I can't tell if I want to eat your balls or keep them in a jar." he said. Of course he would not eat Piotr's balls. They were government property. Once they were removed, he would have to give them up to the proper authority where they would be tagged and put on a shelf with all the other mutant balls. And no one would ever have fun with them again. Dr. X wondered if the whole point of government in the first place was to prevent people from having fun.

Piotr's cock on the other hand, was not the property of anyone save for Piotr. And his rights were taken away when he immigrated to the country as a mutant. If Dr. X wanted to keep Piotr's cock as a souvenir, the young mutant had no means for recourse, save for physical revenge enacted by his mutant friends.

Dr. X decided he wanted to have more fun with the Russian before it came to the castration. He climbed up and sat on the huge man's stomach. He unwrapped the lube and covered an index finger with it. He slowly worked it inside of the young Russian's love tunnel and began to work it in and out slowly. It was tight though, but Dr. X was overwhelmed with the feeling of the overall size of the young mutant. It was nothing like an animal by any means, but there was no other way of describing the sexual exchange between two being of such varying size. He worked a second finger into the hole and started sucking the tremendous cock again. Soon the cock started to get hard little by little. In his mind, Piotr knew it was wrong. He wasn't gay. But it felt so good. He fantasized about Kitty Pryde giving him the oral sex he was receiving. If Kitty had a kinky side and wanted to finger his ass, he was ok with it. That was his only coping mechanism. Within seconds, he was hard as a rock and standing a few inches taller.

"My stars and garters," Dr. X exclaimed, absolutely astounded by the size of the erect penis in front of him. He regretted saying anything as Piotr's fantasy for Kitty vanished at the sound of the male voice.

Dr. X climbed down off of the trapped giant. His own cock was rock hard. Piotr's asshole was now ready to be fucked. Dr. X stood in between the mutant's spread legs. He giggled gleefully as he had to pick up the immense ball sack just to get access to the asshole. He pressed his cock head up against the puckered area of flesh and then shoved his lance inside. It was incredible. Piotr felt it too. Dr. X quickly worked up to a frenzy. He was fucking the young mutant's ass with building vigor. At the same time he was jerking the huge rod. It was long enough that he could suck the cock and fuck Piotr's ass without even having to bend over. Piotr's own cock was hard at this point. Dr. X was about to cum. Piotr was about to cum as Dr. X sucked his tremendous penis, biting the shaft and ramming it into the back of his throat.

But Piotr got another idea. He knew after this encounter was over, he would lose the manhood that was giving him so much pleasure. He thought if He was going to lose his, Dr. X should pay the same price. He knew his ass cheeks could not hurt the Dr., but the armored asshole of Colossus was more than a match.

"Ugh!" Dr. X exclaimed as semen erupted from his shaft, filling the mutant's rectum with warm sperm. Suddenly there was a crackling of energy around Piotr's skin, as it hardened and became living organic metal!

Piotr clenched his butt cheeks together, trapping Dr. X's cock. Dr. X tried to pull out. He knew if Piotr's entire body became metal, he could easily tear his dick off with the power of his metal ass cheeks! He pulled out as hard as he could, feeling blood blisters emerge on the tip of his penis. The transformation was almost complete!

At the last second, with the aid of the lube, Dr. X was free! He held his wounded cock preciously. After a minute, he looked up and found Colossus on the table, his metal skin reflecting the lamp light from over head.

"What do you think of that, Tovarisch?" Colossus sneered. "I almost got you. Ha,ha,ha,ha!"

Dr. X smiled good naturedly. He knew that despite his current wound, he still held all the cards in his hand.

"That was good 'comrade.'" he said, "but indeed your efforts were lost." He slowly climbed on top of the Russian behemoth and straddled his chest. "I knew I should have bottomed to you." Dr. X suddenly felt another rush of his own libido and he began jerking his own cock again despite the pain. For once, Colossus lost the hope in his eyes.

"I notice your metal cock is still hard!" Dr. X leered. "I've reviewed your profile. It says that once it's hard, it stays that way till you become flesh again."

Colossus said nothing.

Dr. X wrapped his palm around the metal cock. It was warm the way an oven is once cooled from a day of cooking.

"OOOoooohhhh," he said, "You know I've decided. I want this." A look of panic filled Colossus's eyes.

Dr. X spent the next several hours trying to remove Colossus's penis and testicles. Wearing nothing but a welding mask and a pair of gloves, he used a plasma cutter to burn through the organic steel flesh. But the plasma cutter did little more than leave a burnt residue on the surface.

Next Dr. X used a laser. Then two lasers. He positioned them just right, but the effect was the same as the plasma cutter. For a laugh he used a gun and had a laugh emptying a clip of .50 calibur rounds on the young mutants' manhood. Captain Reece oversaw this and shook his head as Dr. X seemed to be more playing than engaging in scientific duties. Next came the industrial jackhammer which only made Colossus shoot semen all over his own belly for a change. Dr. X was happy to document that in his paperwork.

Finally Dr. X had to go to restricted areas in the base to retrieve the adamantium circular saw. He was quite pleased that for all this time, Colossus had never lost his erection. He hoped it would continue after he had separated it from his body.

"If this doesn't work," Dr. X sighed, "I swear I will cut my own dick and balls off and mail them to Senator Kelly."

But it did work. And when Colossus saw the adamantium cut through his penis like a hot knife through butter, he screamed in anguish. There was no pain, but the thought that he would have no penis when this was all over was more than he could bear. The giant metal penis hit the ground below the table with a heavy metal KLANG!

Next came the balls. When Captain Reece held the glass container for the balls to go in, Dr. X made him go back for a plastic one. When the plastic one was too small, they went and cut an empty plastic milk container in half and threw the "9054 : Piotr Rasputin : Colossus" sticker on it. Colossus's testicles went in the jug (after they had cooled. They saw made them exceedingly hot).

As Colossus cried tears into his armpits, Dr. X and Captain Reece sat on the end of the table by his feet.

"You know Grigori Rasputin was also castrated." Dr. X said.

"I did not know that." Captain Reece implied.

"I wonder if Piotr here was of any relation."

"Yeah, he is." Captain Reece said. "It's in his file."

Captain Reece put the container full of Colossus's huge metal balls on a gurney and wheeled it down to research where they would be recorded with the rest of them.

Meanwhile Dr. X kissed the crying Colossus on the forehead. "This has been a great night, really." And then they wheeled the young Russian away. Dr. X never saw him again. Colossus's giant metal penis on the other hand, was mounted on a stand and placed in Dr. X's underground office. He didn't want to put it in a place where it would be missed visually, because more often than he liked to admit, he had to take it home with him and leave it by the heater for a bit before taking it to bed with him.
