What You Cherish Most

XXX

Sephiroth slowly made his way through Ansem's old castle in Radiant Garden. It was now his castle as ultimate leader of the Darkness. It hadn't taken long for the Darkness to prevail with Cloud, Zack, and Riku as his main Generals.

The Light had become complacent with the destruction of that group of disorganized upstarts Organization XIII .

Hmph. Sephiroth snickered.

Organization XIII. If the Turks had still existed, they would have decimated the Organization with a smirk and a collective middle-finger.

In a way, the Turks still did exist. Reno and Rude had been found on the planet of Port Royal. They had become rum smugglers, or as Reno liked to phrase it, import-export of much-needed medical supplies.

Sephiroth had let them be after brokering a deal for a 75/25 cut of the profits. Turks always liked to live another day.

Sephiroth had made his way up the main staircase and began to walk down the long hallway to his personal suite.

Living another day, Sephiroth believed that term was Cid Highwind's calling card.

When The Final Battle of Radiant Garden had ended, The Light had been soundly defeated. The Captain had been captured, severely injured, but he had decided to go out swinging.

Cid knew it was suicide. But when he was dragged, in chains, in front of Sephiroth, he tried to charge him.

Cid Highwind was gonna die fighting. He didn't die, though, The one and only person that could have stopped him, swirled in front of Sephiroth to protect his only son.

"Vince, Ah'm dyin' anyway. Let the Captain be."

"Yes, Father. Let the idiotic creature have his last wish."

Vincent would not be swayed by either side. He continued to shield Sephiroth with his tall, red-caped body and had Cerberus at the ready, for any who would try to kill Cid. "Sephiroth, honor the deal. Let me take Cid back to Traverse Town. He will no longer trouble you there. I swear on my love and fealty to you. Please, child. It is all I shall ever ask of you."

"What of the Cetra and that irritating Ninja thing? They are not part of the deal. Were you just going to put them in your pocket, when you leave, like stolen silverware?

"Fuck ya say? Aerith and Yuffie are livin'?"

"Of course they are, Cid. As soon as the battle commenced, I garnered their location and picked them up myself."

"Bullshit! Ya mean ya captured them! Vince, ya know Ah hate when ya try to make the shit shiny!"

Sephiroth broke out in full laughter. "Oh, Father! I understand now! Marriage to Cid is your ultimate means of atonement! It has to be, or else it's that ingrained Turk yearning for self-abuse kicking in. Cid Highwind, self-flagellation at it's finest!"

"Jest a little to the left, Vince. Ah'll lighten yer load of about three hundred pounds of psycho."

Vincent Valentine had had enough. He fired Cerberus in the air. "I will discuss this no more with either one of you! Cid, we will speak of this later; once you are safe! Aerith and Yuffie are already waiting in the Gummi Ship. Sephiroth, I will contact you later once we arrive back in Traverse Town."

Sephiroth had shrugged. He hadn't really cared anyway. He had just liked to piss off Cid.

"Hol' on one moment, Vince! What about Leon? Ain't seen hide ner hair of the Lion. If'n he's dead, Ah wanta bring his body back with us. Should be burried near his kin."

Cid had a bad feeling when Vincent lowered Cerberus and wouldn't look at him. "Okay, psycho. What sick shit ya got planned fer Leon?"

Sephiroth folded his arms against his chest. If it wasn't for the evil smile on his face and his fiercely glowing cat-eyes, he would have seemed every inch the proper General he was. "Not sick at all, Captain. In fact, Leon is to be given the highest honor in all the worlds. He is to become my mate and mother of my children. Such beauty should not go to waste, and his leadership qualities will work well, in the care of all the children he will be having. In fact, I would say he will be so busy, betrayal will be the last thing on his mind."

"The fuck? Leon'll die first befer he births yer spawn!"

"I think not, Captain. Babies have a way of changing your perspective." Sephiroth motioned his head meaningfully toward his own father, Vincent; who now looked like he was going to put Cerberus to his head and pull the trigger.

Cid knew when Vincent was at the danger point. "Shit! Shit! Shit! Fuck-it-all! Fine you win! Git these here chains offa me, so Ah can get mah husband offa this rock and away from yer infection."

Sephiroth loftily motioned his hand, Heartless appeared, and unlocked Cid's chains. Cid's many wounds were also healed.

Cid hastily ran up to Vincent and ran his hands up and down Vincent's arms. "Vince, Ah'm here. Don' be all hidin' in that sad place in yer head. We'll go now and be all happy in Traverse Town jes' like ya want. Aerith, Yuffie, you, and me, one big family."

Vincent's eyes cleared from their suicidal haze and sleepily looked into Cid's. "Cid, I'm tired. Can we go home?"

Cid rapidly nodded his head, in relief, now that Vincent was not in danger of catatonia. "Sure thing, hunny. We're leavin' right now."

Cid started to steer Vincent to the Gummi ship, when Sephiroth stepped forward.

"Father? Would you like me to contact you when the first baby's conceived?"

Vincent half-turned in Cid's strong hold and gave his son the most joyful smile that Cid had ever seen grace his face. "I would like that very much, Sephiroth."

Sephiroth walked forward and enclosed his father in a tight embrace.

Cid had moved slightly away, not wanting to be anywhere near Sephiroth.

"I am sorry for causing you distress. It is just too much fun to jibe the Captain. I expect to see you healthier when you come to visit the children. Their reliance on your love and wisdom will far exceed mine."

Vincent slowly nodded, his smile widening.

Sephiroth released him and directed him back into Cid's hold. "Take good care of my father, Captain. He has much to look forward to, in spite of you."

"Jes' shut yer trap and mind yer own! Ah've been takin' care of Vincent Valentine while you were still a half a body in a crater.

With that, Cid and Vincent left Radiant Garden for Traverse Town.

Sephiroth passed by the shared rooms of Cloud and Zack. The sounds he heard emanating from the suite made him smirk. Ah! Poor Puppy! Guess his much-needed nap was short-lived after all!

"Ger! Gah! Ah! Ah! Hah! Cloud! Ah! Ah! Chocobo, easy! Take it easy! Ah! Hah! Hah! Ah! Remember the babies! Hah! Ah! Ah! Ah!

Sephiroth couldn't help but peek. It wasn't like he hadn't seen it all before.

Hmm. Poor Zack, indeed, seems Cloud already wore out the back-door and moved to the front.

Sephiroth shook his head in bewilderment.

Before Zack had died, Zack had been the assertive one on top of Cloud, never domineering, but he was the man. When he was brought back to life, by the Darkness, he was met by a far different Cloud than he had left; holding a big sword he couldn't carry, in the pouring rain.

This Cloud was full of bleak pain and yearning desperation. He was also way, way more powerful than Zack.

Zack had barely said, "Hiya!", before he was butt naked, legs spread wide, by an obsessed, rutting Cloud, and staring up at a very white ceiling.

Zack also came back slightly altered from when he left. Not only did he still have the male gear that he died with, he also came with a full set of female reproductive organs, too.

Zack, being Zack, had taken it all in stride. He just shrugged and stated that it was just more parts that Cloud could play with. Play with them, Cloud did. Zack was pregnant with twins before he could blink. Fraternal, at that.

The Darkness altered Zack this way for one reason.

Power.

The Darkness, never wanting to relinquish power to the Light again, wished for its warriors to breed often, thereby, spreading their dominance further over the Worlds.

The stronger the warriors, the stronger the children; who would grow up to be even more powerful warriors than their parents

XXX

Zack.

Sephiroth resumed his long walk, leaving an impassioned chocobo and a wailing puppy behind him.

If it wasn't for Zack, this all would never have come to be. Cloud and he would still be having their endless battle, over and over, until the end of time.

Cloud and Sephiroth were once again, staring at each other across the Dark Depths, ready to begin their battle, when they both heard the voice of the Darkness calling out to them.

The Darkness whispered that a little puppy had come under its care and it missed them both very much. If Cloud and Sephiroth agreed to unite to destroy the Light for good, their Zack would be returned to them, alive and well.

Both Cloud and Sephiroth raised their swords in suspicion against the Darkness. They both knew there was no honesty to be found there. The swords lowered when a Darkness-powered window opened in front of them. It showed a terrified Zack shivering and crying softly because he was all alone in the Darkness.

Cloud's heart broke when he heard Zack crying his name out like a mantra to help keep his own sanity.

Sephiroth was enraged. Zack had been his best friend and right-hand man.

To Sephiroth, it was Zack, just by being alive, who taught him what was the best about humanity.

"Zack, I'm here! I can hear you! I'll get you!" Cloud ran past Sephiroth and jumped toward the window, which closed before he could get through. He was left lying facedown on the ground, pounding one fist in frustration.

The Darkness repeated its request and then Sephiroth felt its presence leave the Dark Depths.

Cloud laid flat, slowly got up, and then looked into Sephiroth's eyes.

They both nodded.

The Light never stood a chance.

With Cloud and Sephiroth united under a common cause, and Zack speedily returned, it was not long before the Worlds fell to the Darkness one by one.

The downfall of the Light began in Destiny Islands.

Riku's relationship with Sora had not panned out as he had planned when he had returned.

Sora had hooked up with Kairi and had essentially taken Riku for granted.

When Cloud, Sephiroth, and Zack showed up to ask Riku to take up the mantle of the Darkness again, Riku was quick to join.

Sora, of course, fought for the Light but was beaten down by Sephiroth, himself. It was only through Riku's reassurances that Sora would behave that the Keyblader was even alive.

Riku and Sora then moved to the Castle to begin their new lives.

Riku, fearing that Sephiroth would still flat-out kill Sora just to be sure, kept Sora hidden away as much as he could.

XXX

Sephiroth, finally arriving to the door of the main suite, gave a little laugh.

Riku shouldn't worry. The Darkness surrounding Riku was essentially smothering Sora's abilities. It also helped with the Keyblader now being pregnant. The poor boy was so small and fragile. All he did was sleep and cry.

Speaking of crying, Sephiroth opened the door to the sound of quiet sobbing. He walked in and softly closed the door behind him.

Sephiroth removed his gloves, long jacket, and stomach cover, essentially leaving him with just his pants on and bare-chested. He sat down and removed his thigh-high boots and left them by chair.

Stealthily, Sephiroth moved to the huge bed and pushed the covering lace curtain away.

Squall Leonhart, once known as Leon, was curled up completely naked, on his side, in a very small ball. His hands were bound by leather strips in front of him. His hair had grown out these past months so it now fell past his shoulders in long, brown waves. Even with Sephiroth essentially imprisoning him in this bedroom for the past year, he had not lost any of his natural muscle tone and his skin still had it's lightly burnished glow.

With a sigh of pent-up lust, Sephiroth leaned forward and lightly ran his big hand along the curve of Leon's ass. He jerked up, gifting Sephiroth with a gaze of huge, tear-filled, blue-gray eyes. He scooted up as far as he could against the bed's headboard.

Sephiroth smiled serenely at Leon's reaction to his presence. "Your wait is over, Little Lion. Tonight, we shall conceive our first child."

Leon clutched his bound hands against his chest and bent his knees to his negatively shaking head, in a futile attempt to cover his nakedness. "Sephiroth, please. Just take me from behind again. I'm not meant for that. You're too big. You'll tear me apart."

Sephiroth tilted his head in thought, still smiling. "Hmmm. You might be right. Let me see for myself."

With that, Sephiroth grabbed Leon's legs and yanked his squirming body back to the middle of the bed. He roughly separated Leon's legs and regarded the Darkness's handiwork. He leaned down and gently inserted one finger in Leon's new opening located between his balls and his anus.

Leon wiggled even harder.

Sephiroth frowned and slapped him harshly on the ass as a rebuke. "Little Lion, stay still or this night will be worse than the one where I took your other virginity."

Leon instantly halted his wiggling in fear and in memory. When Sephiroth took him anally for that first night, even with the multiple castings of Curaga, he still could not walk for a week.

Sephiroth inserted a second finger and deeply frowned.

With the fear, Leon was tight and almost bone dry. This would not do.

Sephiroth hunkered down between Leon's quaking legs, removed his fingers, and inserted his long tongue into Leon's opening.

Leon swiftly inhaled his breath and, even though he had been warned, attempted to rotate his hips away and push Sephiroth's head away with his tied-up hands.

Sephiroth firmly held Leon's hips still and ignored the prodding of Leon's hands. He began to alternate between poking his tongue and swirling it inside.

When Leon's hips began to move in a primal rocking motion, Sephiroth added his fingers and also began to rapidly lick the little bundle of nerves above the opening.

Leon couldn't think. All his brain registered was tongue and fingers. It felt so good. The harder Sephiroth tongued him and the more rapidly he rubbed, the quicker his will to fight and fear faded away.

Faintly, Leon wondered who was babbling and sobbing Sephiroth's name like a whore. In shock and a little disgust, he realized it was him.

When Leon came, his vaginal muscles tightened around Sephiroth's two questing fingers, his body completely arched off the bed, and a gush of fluid emptied from Leon. His penis had also ejaculated onto his stomach.

Sephiroth completed the act by withdrawing his fingers, leaning back up, and licking the semen off of Leon's stomach.

XXX

Leon so badly wanted to push Sephiroth away; to jump up, and run far, far away as fast as he could. He knew it would be futile, though. He had tried that the first night. Fighting, screaming, throwing fire, he still ended up face-down on the bed, hips held high, as Sephiroth rammed into him over and over again.

It never ended, all night long. Positions changed. Leon would lose consciousness and he would then awaken to Sephiroth still pounding in him.

If it was just that, Leon could endure. He had lost and, unfortunately, he was also the spoils.

But Sephiroth made sure, that while there was pain, pleasure overruled all. Leon came every time, moaning and wailing Sephiroth's name. All the while hating his body, and himself, for its betrayal.

Leon began to quietly weep knowing this time would be no different.

Sephiroth moved back up between his legs. The head of his penis nudging Leon's now softened, moist opening. "I am untying your wrists now, Little Lion. I do not believe that you want to know what will happen to you if you try to attack me now."

Leon looked down with a sob and nodded.

Sephiroth freed his wrists in an instant and wrapped Leon's arms around his neck. He bent down and began to softly kiss Leon, interspersing the kisses with little licks of his tongue, entreating Leon to let him in.

Oh! Leon's heart ached. This was the worst. Small pains would be overlapped by gentle, loving pleasures, confusing him and leaving him lost. Knowing there was no turning back now, Leon tightened his embrace around Sephiroth and opened his mouth for his tongue.

Sephiroth's tongue entered and tasted every corner of Leon's mouth, reveling in his mate's taste. He then withdrew and began to leave a little trail of kisses from Leon's cheek to his chin, down to his Adam's Apple. He then nudged to the side to feast on the side of Leon's neck.

While this was happening, and Leon was not paying attention, Sephiroth had slowly, caressingly, moved his large hands downward to take firm hold of Leon's hips. When he moved to Leon's neck, he had inserted the tip of his penis into Leon's now-dripping opening.

When Sephiroth deemed Leon relaxed enough, he once again took firm control of Leon's mouth with his own, tightened his hold on Leon's hips, and speared him in one thrust.

Leon's eyes were shocked wide open. Sephiroth had only gotten halfway in, but the pain was unbearable for Leon. He began to beat against Sephiroth's shoulders.

Sephiroth could feel Leon's screams that he had covered against his mouth. He pulled slightly out and thrust in again. This time all the way in. He halted so Leon could adjust as well as he could. Sephiroth released Leon's mouth so he could breathe.

Leon wailed in agony. "Oh Gods! Oh Shiva! Take it out! I was right! I was right! Take it out! Take it out!"

Sephiroth ignored Leon's wailing. He had tried to be more gentle this time but Leon's clutching tightness and his beauty through his tears was quickly ungluing Sephiroth.

Sephiroth resumed his thrusting, making sure that his lower body was giving friction to that little bundle of nerves above Leon's opening.

Sephiroth raised himself on one arm, deepened his thrusts, and began to harshly fist Leon's erection in time with his thrusting.

Aaahhh! "No! Let go! It's too much! Too much! All tight! Too tight! Ah! Ah! Uh! Coming! Uh! Uh! Gonna come! Eh! Neh! Ah! Ah! Ha! Coming! Ah! Ah! Ah! Ah! Aaaahhhhh! Leon's sperm shot out of his penis, flying over his stomach, chest, and even on his face.

Sephiroth let go of the still dribbling penis, firmly gripped Leon's hips in place and began to thrust at a blinding pace.

Leon tightened his hold on Sephiroth's shoulders just trying to hold on and not get his head bashed on the headboard.

Sephiroth could feel his orgasm swiftly rising. "Leon, open your eyes. Look at me. I want to see your face when I come inside you."

Leon's eyes flew open and they searched pleadingly for some sympathy in Sephiroth's face. There was none. "No! Don't! Pull out! Pull out! Come in my ass or my mouth! Just not there! Not inside! Don't do this to me! Sephiroth! Please!"

Sephiroth just smiled that gentle smile that was exclusively for Leon when he amused him. His hips stilled flush against Leon's pelvis and he released a low groan.

Leon, knowing what was going to happen, began to scream, shoving Sephiroth's shoulders, planting his feet so he could jerk his torso away from Sephiroth. It was too late.

Sephiroth's blazingly hot sperm exploded up Leon's canal, filling his ready womb to capacity. His penis continued to pulse, pushing more and more sperm up Leon.

Leon felt his lower stomach swell a little with the excess warm seed. He covered his eyes and sobbed. Trapped. Trapped. No escape. Not now.

Sephiroth had learned of Leon's past in the Orphanage. His issues of abandonment. He knew Leon would never abandon his baby, no matter how badly things were with Sephiroth.

And if Leon was actually able to escape, he would have to escape alone.

Sephiroth had come to truly love his Little Lion, but he would see him dead before he would allow him to take his babies from him.

Once Sephiroth considered the deed completed and his new child was being formed even now, he leaned back and slowly pulled out. His penis covered in blood, excess sperm and blood gushing out from Leon's quivering opening.

Sephiroth looked down at his handiwork. Good. Leon wasn't badly torn. A hi-potion would do the trick and then they could do this again.

Seeing Cloud and Zack earlier, it had inspired Sephiroth. He wondered how many times he could take Leon vaginally before he passed out. Well, he'd find out tonight.

Sephiroth laid beside a sobbing Leon and gently removed his hands covering his eyes. He leaned over and gave Leon a gentle kiss.

Sephiroth looked into Leon's saddened blue-gray eyes and laid his hand over Leon's lower stomach. "Don't cry, anymore, Little Lion. What's done is done. The babe is growing as we speak. This distress will just weaken you and potentially harm our child. I shall let you rest for a little. Then we can start again."

Leon, depressed and exhausted, did as he was bid and allowed Sephiroth to enclose him in his strong embrace. He quickly fell into a deep sleep.

Sephiroth whiled away the hour, composing the letter to his father in Traverse Town about the new baby.

Vincent had been waiting for so long.

Sephiroth smiled and tightened his hold around his Little Lion and new cub growing inside.

Father had been right. Family is everything.
