First chapter of my Fullmetal Alchemist/Code Geass crossover. This is mostly an experimental thing that my best friend had a spaz over xD But I will continue working on it so she doesn't hurt meh O.o

Bon appétit.

Lelouch Lamperouge adjusted his neatly folded cuffs, smiling faintly at himself in the mirror. He'd finally done it. After a seemingly endless search he'd tracked down the perfect partner at last.

Roy Mustang.

The perfect mix of intellect and physical strength. With the alchemist's skills and Lelouch's brain, they would be nothing short of invincible.

The only thing left to do was meet him.

With an amused smile he stepped out of the stairwell into a lavishly decorated hotel hallway. He was up on the seventh floor, the key to the colonel's door resting gently in his pocket. If he wanted this to be successful, he had to strike quickly. The colonel would only be in town for a few days so he didn't exactly have much time.

The dark haired prince moved along the corridor, counting off the door numbers until he reached the one he was looking for. Letting himself in, he noticed that the apartment was unoccupied. There was a blue uniform tossed on the bed, crumpled into a heap. Lelouch folded it before moving on to sort through the bedside table drawer.

He found a notepad with a few scrawled notes in it, two pens and a leather wallet.

Wait…

A wallet?

He heard the safety catch of a gun click behind his head before the business end of a pistol was pressed to the back of his neck. He glanced sideways at the full length mirror, his eyes scanning over the raven haired colonel standing behind him, whose gun it was pressed against his neck.

"Unless you want your head blown off, I suggest you step away from my things." Roy said in a level voice, his coal black eyes boring into the back of Lelouch's head, as was his gun.

"Roy Mustang?" Lelouch asked, still gazing at his reflection in the mirror. The colonel's eyes never moved.

"Yes." Lelouch faltered. This wasn't playing out as he'd hoped. He needed to regain control of the situation.

"Why don't you simply use your alchemy? Why bother with a gun?" Before he could even blink, the colonel had knelt down behind him, the barrel of his pistol shoved underneath Lelouch's jaw.

"You talk as if you think I won't do it." He flicked the safety catch off with his thumb, and the pale skinned prince was painfully aware of the loaded gun under his chin.

"I have a proposition for you." He managed to mutter, reaching out to brace himself against the wall with both hands. The colonel's weight was pressing rather hard against his back and he swallowed nervously.

"What kind of proposition?" Roy inquired, quickly spinning Lelouch around to face him, gripping his collar tightly in his hand, the pistol still jammed up his chin. The soldier's black eyes were slightly narrowed as he gave the prince a onceover. He was young. Only about eighteen or nineteen. At least ten year's Roy's junior. With a grunt the colonel gestured for him to answer.

"Can I show you?" He asked hopefully, his face falling at the other man's blank expression,

"No." Was the blunt answer. There was a moment of silence before he asked "Who are you?"

"My name is Lelouch Lamperouge." The prince answered, somewhat more calmly. Introducing himself was something he could definitely deal with.

"Lelouch…" Roy murmured thoughtfully, his gloved hand sliding down from the prince's throat. "What is your proposition?" His fingers were fiddling with Lelouch's breast pocket, tugging softly at the white fabric. It was distracting the young prince, who already had a libido to match the size of a large Greek island.

"I would like to propose some sort of…" Lelouch paused, swallowing again. "…relationship." Roy's expression never changed, excluding a miniscule eyebrow raise. Lelouch took it as permission to go on. "I've thought about it a lot, and you have to admit, colonel, we would be an incredibly…powerful…combination." His eyes shone as he looked up at the man crouched over him, black eyes completely void of expression.

Roy pulled his hand back and Lelouch instinctively flinched, expecting to be slapped. The blow never came, however, and the colonel simply holstered his weapon. Lelouch cracked his amethyst eyes open, surprised that he hadn't hit him. Roy was simply smirking down at him, his eyes a dark shade of playful.

"Lelouch…" He began, leaning down to speak in the young prince's ear, his voice a low murmur. "Have you ever been with another man before?" The ebony haired teen flinched sharply, his slender fingers automatically twining into the colonel's dark hair.

"I've…never been with…anyone…" He managed to eventually mumble, his pale cheeks reddening in embarrassment. Mustang chuckled, the sound amused, yet not at all surprised.

"I thought as much." Lelouch gasped as the older man pulled him into his lap, cradling his legs on either side of his own hips as he pushed the Britannian prince back against the wall. "Oh look…" Roy muttered, feigning annoyance. "Now you've gone and got me all excited." The teen was painfully aware of his own throbbing erection straining at far too tight pants, and guessed that the colonel was in the same situation.

White gloved hands glided swiftly down his torso, unbuttoning his white shirt easily to expose that pale abdomen. Lelouch offered an awkward thrust upwards with his own hips, his blush deepening as the colonel chuckled in his ear.

"Let me lead. I know what I'm doing." Lelouch turned his head to the side in an attempt to hide his embarrassment, feeling Roy's lips brush along his jawline before a hand grasped his chin, bringing his head back around and forcing his lips down on the prince's. His lips were scissored open and Roy's tongue dipped into the moist cavern that was his mouth, making the teen moan.

Lelouch could feel the colonel's hands on his hips, grinding his pelvis against Lelouch's and in turn pushing him back against the wall, effectively trapping him. It was an awkward position for the prince to be in, and he could already feel his leg's cramping.

"Can we move to the bed?" He gasped, his tone much less firm than he would have liked. The colonel obliged, hoisting the youngster onto the soft white sheets. He deposited Lelouch on his backside, letting his legs dangle over the edge before crouching between pale thighs, having removed his pants in the process.

He heard the young boy moan as he enveloped the prince's burning erection in his lips, through the thin black fabric of his underwear. The teen bucked and moaned deeply on the bed when Roy pushed his legs further apart to give himself better access.

"What…what do I call you…?" Lelouch panted, his perfectly trimmed nails digging into the colonel's scalp as he whimpered in illicit pleasure, every noise begging for more.

"Call me whatever you like." He replied, his tone still amused.

"But…I've never…I've never done this…I don't kno-NnnnggggAHHH!" His head snapped backwards as Roy sucked intensely on the boy's cock, nipping at the already sodden fabric clinging to his burning skin. He pulled back suddenly, standing to lean over the younger man.

No…he wasn't a man…He was a child.

The colonel pushed Lelouch flat onto his back, lifting the boy's legs over his shoulders as he positioned himself at his twitching entrance. The prince tensed, waiting to receive him with closed eyes and baited breath. He knew it would hurt.

Roy pushed himself into Lelouch, feeling the searing heat of the youngster squeeze him tightly. Almost painfully tightly. Lelouch's agonized cries filled the small apartment and tears welled in the corners of his eyes. The colonel gently wiped them away, licking the salty tears from his fingers. Bony heels dug into his spine when the prince wrapped his legs tightly around his waist, grinding his hips against the older man's in sharp, jerky movements.

"Don't move." Roy ordered, his hands moving to guide Lelouch's hips. "I'll do it for you." The boy cried out with pleasure mixed with pain as the colonel took over, moving against the other's pelvis in a smooth, rhythmic action. Flesh against flesh. Sweaty bodies moving together, carried away in the ecstasy and unspoken pleasure of the moment.

And suddenly it was over. Lelouch had come with a loud cry, letting the tears spill down his cheeks as Roy stroked that spot. It was agony for the young teen, who Roy guessed had never come before now.

Roy leant down to crush his lips against the youngsters, listening to his pained moans of protest as the colonel never ceased moving, driving the inexperienced Lelouch beyond the point of pleasure and into the realm of agony.

"Stop…!" He whimpered, his voice begging with the older man. "Stop! Please…" He was sobbing now, the tears leaving glistening tracks on his lighter than porcelain skin. Roy paused, twisting his fingers into Lelouch's hair.

"Why are you crying?" He asked, his voice void of the gentle emotion that should accompany that sentence. Lelouch's deep amethyst eyes opened, his expression pained still, even in the usually warm afterglow.

"I've never done this…I don't know…It's so strange…" He whispered, his fingers digging into the sheets by his sides. The colonel chuckled, startling the traumatized prince.

"Lelouch. This is how it is with a man. It will get less painful, but it will generally always be like this." He told him, moving back and pulling out of the still dripping prince. Lelouch weakly pulled himself into a sitting position, wincing as tears sprung to his eyes again from the pain.

"You almost tore me apart…" He muttered, locking eyes with the colonel. Calm onyx eyes gazed levelly back at him as he sat there, still trying to catch his breath. The colonel smirked as he buttoned his shirt up.

"Are you sure you still want that relationship?"
