Biological Lessons

Disclaimer: I do not own the game or the characters. So that make us even.

Summary: Meet Sephiroth, a teacher at Midgar High. Meet Cloud Strife, a stubborn hot tempered 16 year old trying to earn a reputation in high school. Mix these two together and chaos will be the result. SxC Yaoi. AU.

A/N: First FF7 story. Be nice. Since this is the first time I wrote a FF7 story, so the characters are not really that 'In-character'. Hope you forgive me for that.


Hands cornered him, not letting him have any chance of escaping. The younger let out a soft moan as teasing lips finally found the other, pressing onto his own. This made the teen yelped out in respond as one hand 'slipped' under his shirt, squeezing and brushing across the tense muscles. The older snickered in victory.

He loved the way his prey reacted. Every sound, every movement made his skin jumped with glee. Those blue cerulean eyes tilted his head up, digging his hands onto the silver hair on the older. The way he looked… god. He wanted to ravish him right at the spot. He looked so vulnerable, so weak.

Not like the usual stubborn and rebellious teen he had met earlier. Not that he's complaining. Since when he was one to? Never. He was never one. He was having an upper hand in this. And he loved every minute and second of it.

He moved closer so that his face met the other's exposing neck. That tie was out of the way. He thought. Now he could have some fun. He kissed the other's neck hard and rough, making sure that the blonde was feeling alright on not to faint during this. Sucking and kissing hard enough to make his teeth scraped roughly against the spot.

Blood repeatedly gushed into his brain in an endless cycle trying to maintain the teen's consciousness. Ignoring the teen's hands which were practically clawing his back, he continued the process of biting and sucking, pulling up one hickey after another. Pulling back, he happily admired his work of art.

Shifting to allow more space for him to lean downwards, he used his hands to roughly pin the blonde to the wall. Cloud felt so utterly defeated and harassed. But it felt so good. Better than heaven itself. And the older man wasn't showing any sign of leaving him like this. He wanted to push him away, punched this arrogant bastard in the face and leaved in a huff.

But he couldn't. He felt so helpless under the man's touch. Not to mention the way he bore into him was powerful enough to make his knees go weak. The older quickly used his other hand to unbutton that fucking uniform. He had to. It was restricting him from his 'inspection' duties. Oh yes, an inspection it was.

He smirked to himself as he was finally rid of the boy of his rugged uniform. Lips came in contact with skin and it made the boy shuddered in pleasure. It was what he had wanted. It was the punishment that the blonde had deserved after making such a scene in class earlier. He dragged his mesmerizing lips across the pale chest, stopping every now and then to earn a reaction from the boy.

"Humans have their most sensitive spots too and it's up to you to find it." He had taught the class earlier about the entire nerve system. And some had the nerve to interrupt it.

Cloud was now on the urge of a nervous breakdown. That felt so darn good… he didn't want to believe in it. But this all looked too real to remind him that it was just a sickening fantasy. The elder's tongue found his prize of affection –a hard nipple before forcefully licked at it. This earned more gasps and groans than the usual.

That was it. Cloud strife, aged 16, stubborn and hot tempered fifth year snapped.

"Ah…g- Get OFF ME! YOU RAPIST!"

With a newfound strength he never knew he had before, he pushed the older man off him causing the man to blink in confusion. Panting the younger then took off in another direction, leaving him smirking mildly at the path.

That was indeed interesting for Sephiroth-sensei. He had discovered more about his new students. And this one was his latest specimen.

Stubborn as hell Cloud strife was cursing every colorful vocabulary under his breath, stalling every now and then to glare at the juniors who appeared more than five meters of his radius. Thankfully, they gradually stepped out of his sight. Who knows how many blood sheds must the principal prevent?

"fuck that rapist…" he cursed blindly, hands shoved into his pockets in a rude manner. The action and the way the blonde's brow were furrowing together didn't go unnoticed. An English teacher heard him and faced him, wanting to give him a detention. But the eyes. They looked like they could kill.

So she left it like that, not bothering to pursue the matter anymore.

He had never been this angry in all of his life! Sure, Cloud was quick-tongue and had languages which could kill but he was never utterly pissed off like this. That man was really getting on his nerves. He didn't know what he sees in him! First he was kind and gentle. And the next thing, he was an arrogant bastard that deserved to be punched and kicked out of the school ground.

God damn it. He hated his life.

Spiking off in a corner, he held his breath as the school's number one prankster; Zack pounced on the unarmed teen.

The way Zack acted was promptly asking for a death sentence.

"Spike! I foooound you!!" He spoke loudly, grinning madly.

Cloud sighed before proceeding to pull the black-haired teen from his back. He was about to ask him what have he been doing but immediately shut his mouth up.

Those onyx eyes were glinting in victory. Of what Zack had managed to pull on another poor victim, Cloud suddenly had the feel of not wanting to know. Besides, there was one thing which he had learned from Zack. The less you know what he had been doing for the past hour was one thing which should have been left unknown.

Instead he resolved for a better word, "What?" he snapped, leaning against the school's corridor.

Zack resumed his goofy grin. "Man, where have you been for the whole time? I have been looking all over for you!"

Cloud blushed at the statement as dirty thoughts (coughSephirothcough) started flowing into his brain, contaminating it even further. The black-haired teen studied his friend's face, noticing the extremely large love bite which definitely wasn't there before. A slight smirk formed on his lips. His eyes were still staring into the hickey.

"What the-?" Cloud nearly shrieked girlishly as he saw what Zack was staring at. He grimaced, knowing that his friend won't shut or leave him the hell alone on it. "Stop staring, Zack. Or else I will dig your eyeballs out." He deadpanned, clutching his shirt tightly.

"Spike..."

"Don't get me started, Zack." Cloud glared.

"But Spike…"

"I said don't get me started!"

"Spike! Behind you!"

"Huh?" He whirled around, understanding what Zack had been trying to say.

"ZACK! THAT FUCKING EXTRA TERESSTERIAL IS CLOSING IN ON US!" Cid yelled loudly, nearly crashing into an unexpected Cloud.

Zack's carefree expression was gone in a flash, only to be replaced by horror. "SHIT! You mean he found out?.!"

Cid nodded quickly which reminded Cloud of an electronic robot. He chuckled mildly, his anger forgotten. A curious look adapted onto his features again, suddenly having the urge to know what exactly had the two idiots pulled this time. Zack nervously asked. "What about Mr. goody goody Valentine? Did he get caught too?"

"What did you guys do?"

"Just spiking some coffee on the Chemistry Teacher, drugging him, tying him onto the chair. You know. The usual stuff." Cid pointed out bluntly.

Somehow, Cloud felt pity for the man.

"Ya meant Vicky? He's on all fours right now." He continued again, exchanging drastic looks behind his back as if searching for a lurking predator.

"Damn! It was supposed to be a secret!" Zack cursed, fiddling with his belt. The obnoxious blonde narrowed his eyes, and again. Same like Zack. He noticed the large red love bite just below Cloud's collarbone.

"Hey Cloudy. Where the hell did you get that?" He pointed rudely to Cloud, his eyes glinting in anticipation. "Poor Kadaj will be heartbroken." Both of the teens laughed.

"Har Har Har. Very funny." Cloud mimicked Cid's tone, glaring every now and then.

They were about to make more remarks on the blonde's new deco when a loud voice thundered across the halls, sending chills down every students' spines.

"HIGHWIND AND LOCKHART!"

"Oops! Bye Spike! Gotta run! Tell my sister to buy me a coffin."

"There's the E.T. now! See ya later…Cloudy!"

Cloud squinted his eyes as Rude came running across him with a murderous look on his face. The bell chose that time to ring so he recommenced his ways into his classroom. Boring ol Physics is going to be next, wondering whether Zack was going to be late again for the next class as usual.

He went to his seat and rummaged through his bag, searching for the ancient Physic's notes. The loud noises and giggles came to a complete stop when the door flung open, revealing no one other than HIM.

THUNK.

Cloud gawked as the bag fell off him to the ground.

The soft smirk widened even more. Girls swooned at his feet as living giggles and blushes mixed within their hearts. Cloud groaned loudly, wanting no other than to slam his head onto the desk.

"Good morning class. Your previous teacher, Rufus, is sick. I will be holding relief for him until he's well enough to teach. I'm now your Biology teacher as well as your physics' teacher."

Screams emitted from the girl's side of the tables as Cloud once more cursed on how fucked up his life was. Dang it. Now he's going to see him two periods longer than usual.

The silver-haired man quietly mused to himself as he ordered the class to turn to page 19, ignoring the frequent cries of females. This will indeed be an interesting year…
