Summary: This is a Final Fantasy VII version of my Kingdom Hearts story 'The Mistake'. In this story, Zack accidentally busts into Sephiroth's bathroom, not knowing that he was in there. Sephiroth had just gotten back from his monthly examination by Hojo and he's off his rocker. What will happen? Multiple pairings in the future.

A/N: I just made to make a Final Fantasy VII version of 'The Mistake'! I just had to. I'm planning on doing a Final Fantasy VIII one too and maybe Final Fantasy X one. I just love the idea of every bishounen in the Final Fantasies together. Anyway, I hope you enjoy this and review.

Chapter One: Caution…Slippery When Wet:

Oh, gods…

He had to use it…and he had to use it bad. Why weren't there any bathrooms around when he had to go? He cursed to himself over and over again while his knees buckled together. He was practically humping the air as he tried to get himself not to piss on the floor.

His cheeks were as red as cherries and he thought he was going to fall over when he started hopping like a drunken bunny down the hallway. Many people that were passing by laughed at him but he really didn't give a rat's ass.

His hands gripped the front of his belt and with every jump forward he grunted. His boots made loud thud noises. It was in the late afternoon and he had just gotten finished with the little portion of paper work he planned to do.

I'm about to bust…

He saw a very familiar door. It had a label on it and it said "General Sephiroth". He smiled and felt relieved. Surely, Sephiroth would let him use the bathroom right? He hopped over to the door and his black eyebrows knitted together in confusion when he realized it was unlocked.

Once he was in, he got his nerve back enough to walk normally. He saw that the bathroom door was wide open and the lights were on. His grin broadened.

Jackpot!

With his amazing speed, he dashed for the bathroom and went right for the toilet, not hearing a gasp come from his left. He unzipped his pants and let it all go, getting it all in the toilet, of course. He didn't have a death wish just yet.

"Zackary, what the hell are you doing here?".

His blue eyes widened to saucers as his spine turned into a block of very thick ice. He had just released the last of his urine. With slow jerky movements, he turned his head to the left and caught the sight of a very naked, hot and angry silver-haired man behind a clear shower curtain.

He chuckled nervously as he washed his hands, "H-hey, Seph! Didn't see ya there!".

After he washed his hands, he saw the man's glowing emerald eyes narrowing to slits. The black-haired male couldn't help but notice that the wet version of the general was a very pleasing sight. As soon as he turned to go out of the door, he felt himself being thrown into the door that was now closed by his body.

He felt a strong hand on the back of his neck along with warm breath that tickled the hairs there. His hands were pressed against the door of his own accord He smelled some alcohol on the breath and froze.

Seph couldn't be drinking, could he?

That's when it hit him. The older man must've just come back from his time with Hojo. The crazy scientist usually gave him liquor to slow him down. Every time he did do that, Sephiroth would come back drunk and would have lost all sense of control. That's why they usually lock him up in his room, but Zack guessed that wasn't in play here and now he was at the older man's mercy.

"I had to piss, Seph, and I didn't know you were in here! I would've come in here anyway…", he smirked and winked at the silver-haired man who was giving him death glares.

Suddenly, the general released the black-haired male of his fearsome grip and he landed on his feet. The younger man was spun around to face other man by his hands and was slammed back on the door on his back. His blue eyes stared at the silver-haired general's sleepy face from behind him. He looked like he was about to collapse.

"You're going to beg for forgiveness…", the older man began after he hiccupped. "Get on your knees…".

Is he fucking kidding…?

Zack knew better than to ask that because everything Sephiroth says he means and especially something like that. The look in his bright emerald eyes said everything and he knew that just because the older man didn't have his sword didn't mean he wouldn't be just as deadly with his fists.

"Aw, come on, Seph. It sounds kind of kinky but I'm not gonna d-", the raven-haired 1st class SOLDIER was cut off by a quick and strong fist in the gut, making him fall to his knees like the silver-haired general had asked him to.

The younger man looked up at the older one with blue eyes. The sight of seeing a completely naked and wet Sephiroth was only applying more heat to his loin area. He sighed and figured that he might as well do this before he gets beaten in the bathroom by a very intoxicated general. The most possible result would be death. Smirking, he wrapped his arms around the older man's waist and pressed his face against his naked hips.

"I apologize on behalf of my bladder. It couldn't hold it long enough and made me come here to piss. I have angered the great general Sephiroth and it is my duty of a person of lower status in SOLDIER to drop all of my pride and give you this heartfelt apology", he said, sounding like he was reading something off the floor. "I-".

"Enough…get in the shower", the pale man said with a small smirk.

Had he heard him right…?

The black-haired man chuckled, "I should start apologizing more often".

Before he could even get up on his feet, the silver-haired man pushed the younger man back and ripped off his shoes before picking him up by his shirt and throwing him in the shower with his clothes on.

His back hit the shower wall and the breath was literally knocked out of him. He drooped down to his feet and his shoulder dropped sluggishly. The hot boiling water dripping down on him made him hiss because it was so hot. He didn't recover in time when the older man crushed his lips against his.

His sharp teeth bit the younger man's bottom lip for entry to his mouth roughly. The dark-haired SOLDIER complied by opening his mouth and letting the older man shove his ravenous tongue inside.

His blue eyes widened slightly when the other man's tongue attacked his viciously. He felt the general's fingers on his neckline, trailing down to his collar bone and stroking it gently. His clothes were getting more and more soaked by the second.

The more the skilled swordsman's fingers traveled lower the more skin was revealed to his lecherous eyes. He began nibbling the younger man's collar bone as he stripped off his shirt.

Zack inhaled sharply as he ran his fingers through the older man's rich and long silver hair. A small smile crept onto his features and he wrapped one of his legs around the general's waist.

His eyes rolled to the back of his head when the silver-haired man began sucking on his tongue. It didn't help to stop his growing erection when he felt something poke his loins. He groaned into the kiss and the green-eyed man unzipped his pants.

By this time, his black hair clung to his skin after being drenched by the boiling hot water pouring onto them. He felt the oxygen get sucked out of his body and squirmed violently when he saw black spots in his vision.

Sephiroth must have gotten the picture because he pulled away. The black-haired man began panting heavily as he looked at the silver-haired swordsman, seeing a smirk on his aristocratic features.

The dark-haired SOLDIER reached outward to touch the beautifully crafted muscles on the older man's abdomen but he merely shifted to the right. He stared at him intently with his cat-like glowing emerald orbs and the younger man smirked.

"Why didn't you say anything?", he asked.

"Maybe because I actually thought you would get the idea", the general said.

The raven-haired man rolled his eyes and tried to slip off his soaked pants. He was hopping around as he tried to take off his socks too. He unfortunately lost all of his balance and fell forward.

His face landed right on the naked member of the swordsman, receiving a grunt from the older man. His eyes widened to saucers this time and he looked up and saw the angry look on the man's face. The side of his mouth was pressed against the general's length.

He suddenly started smiling. A playful idea popped into his mischievous mind. He was very lucky to catch the general reaching out for him in time for him to move out of the way. He dashed for the door, wanting to make this fun little meeting into a chase.

Just as he opened the door and started running again, the swordsman kicked his legs out from under him and he went sliding across the floor in the older man's bedroom on his stomach. When he saw the bed in front of him, he sighed.

Just his luck…

His pants had been lost from his body after he slid across the floor and now he was completely naked and so was the intoxicated general. He used the sheets on the bed to help him get to his feet but he standing was short lived because the heated general pushed him on his back on the bed.

"You thought you could run from me, Zack?", the older man purred, making the younger man's member stand straight up now.

"You know…I thought that would really work", the black-haired man said matter-of-factly. "You always surprise me, Seph".

He was grinning like a total idiot, making the silver-haired man arched a perfectly sculpted eyebrow as he crawled onto the bed. He tugged the younger man's foot roughly, pulling him beneath him. The dark-haired man noticed that the general's eyes were very hazy and his pupils were dilated in unnatural ways.

The blue-eyed man looked to his left and saw a pile of black clothing and a very long sword by them. He knew that it was the general's and felt his chin being grabbed and jerked forward.

Before the general could lean down, the raven-haired man slammed his lips against his and slipped his tongue in as he gasped. His hands snaked down on the younger man's toned body and ghosted over his throbbing member.

He inhaled sharply and pushed his hips upwards, connecting it with the other man's length. The silver-haired general growled and pressed a firm hand on his hips, pinning them down.

The raven-haired man growled in disappointment and sucked even harder on the older man's face. He was getting impatient and tired of being teased. He tried everything in his power to thrust his hips upwards but the general's hand didn't even seem like it was budging.

The pale man ripped his lips away from the younger man and started to kiss down his body, stopping at his nipple to claim it into his hot mouth. The dark-haired male gasped and gripped the older man's head, receiving a low growl. He immediately removed his hands and grasped the sheets instead. He could feel his weeping length dripping in pre-cum and it killing him slowly.

The skilled swordsman kissed the younger male firm stomach, sticking his crafty tongue into his belly button. The blue-eyed man chuckle softly. The lapping of his belly button was obviously making him ticklish because he was starting to squirm a little.

"Seph…it…tickles…!", he cried between boisterous laughter.

His laughter drastically changed into full-blown pants as he felt the older man grasp his aching length and stroked it roughly. His eyes rolled to the back of his head and bucked his hips against the firm hand.

"Gn…", he grunted.

He managed to fix his blurred vision and looked down to see the general leaning down with his mouth open. Simultaneously as he did that, the silver-haired man's beautiful green eyes snapped up and connected with the younger man's nervous blue orbs.

The general smirked, "Scared?".

The spiky-haired man chuckled, "Nope…just wondering if my dick will smell like alcohol after this".

"Who said anything about sucking that pathetic organ of yours?", the swordsman teased as he raised the younger male's legs so that his knees were in the air.

"Now, now…you didn't say that last time", Zack boldly joked.

Sephiroth suddenly let out a series of uncharacteristically loud laughter. The black-haired man raised a dark eyebrow. He knew that the general who throwing his back in a fit of laughter was seriously succumbing to the drugs Hojo put in him.

He was so preoccupied with the strange and rare occurrence that he didn't notice the man on top of him positioning himself at his entrance. Without any warning, the green-eyed swordsman shoved himself inside of the tiny hole, completely catching him off guard.

"Ah!", the dark-haired man allowed that yell and many groans rip of his throat.

"I'll make you eat those words, Zack", the general said with a lust-provoked smile.

His blue eyes widened to a shape even bigger than saucers. The silver-haired man pulled out roughly also pulling out another groan from the younger man's mouth. He got onto his knees and tugged the other man's hips to him. He observed very closely as he slowly inserted his thick and stiff rod into the opening, loving how it was deliciously stretching over it with ease.

The blue-eyed male arched his back from the pleasure coursing through his throbbing veins and also was purposely throwing his hips down onto the object that was penetrating him wonderfully. Even though there was a lot of pain, he focused on the pleasure.

This was heaven…

He could literally see stars. The stars danced around him and he was put into a trance. The general pushed the younger man's knees into his stomach as he plowed into him. His hands pushed down on the back of his knees firmly.

The water that they were soaked with turned from cold to hot when the general started going at a rapid pace. His long silver hair tickled the younger man's skin as he leaned over to thrust inside harder.

The spiky-haired man gripped the sheets, collecting most of it in his hand. His eyes were clenched shut by now and he was crying out every time the older man hit his prostrate. His member was still oozing pre-cum onto his stomach. He was quickly building up to his peak.

The general cracked a glowing emerald eye open and gaze upon the younger male's predicament and the sight made him groan. The raven-haired SOLDIER clenched down onto the thick and throbbing hardness inside of him as he splattered his juices on their stomachs, calling the older man's name out loudly and simultaneously.

The stars that were dancing around him multiplied and turned into a whole galaxy…

The silver-haired man let out a relieved sigh as he pounded into the tight entrance one last time to release his liquids into the younger man's ass womb. The black-haired man cried out one last time before he collapsed onto the bed.

"You've eaten those words now?", the general asked.

"Swallowed…", the dark-haired man muttered breathlessly.

A loud frantic knock was heard from across the room and at the entry door. They heard the door click before the silver-haired general could say anything and he growled. He reached over to grab his long Masamune and with great strength and reach he threw the sword at the door.

"Ah!".

A/N: Well…who could that be? Even if he's drunk, Sephiroth sure has some good aim. Please review. There will be a lot more lemons later.
