Chapter Text

“Sephiroth, what the he…” the Young SOLDIER didn’t let Cloud finish his sentence, his tongue distracting him and taking the very first taste of the older man. How Sephiroth had longed for this and a shiver seized his body at finally obtaining it, diving in for more, rubbing the wet appendage against Cloud’s, lapping at the roof of his mouth and feeling a slight reciprocation before the man realized what he was doing and stopped.

He dragged Cloud from the door to his room where he’d first trapped him, devouring Cloud’s lips as long as he could, then threw him onto the bed, not giving the blond a moment to react and try to stop him, Sephiroth would make sure to make his brain stop working so he would stop thinking about anything, if this was right, if he wasn’t taking advantage of his younger companion, thinking about those women…

His stomach churned with contained anger, the jealousy roaring to life again at the mere thought of Cloud’s friends. All of Cloud’s friends bothered Sephiroth, but the girls… the way Yuffie would distract him from his conversations with Sephiroth with her incessant, annoyingly loud talk; the way the blond would let Tifa touch him so casually, for no good reason when he’d tense up whenever Sephiroth did the same. But the worst was Aerith… Sephiroth liked her the most out of anyone else of the group beside Cloud but… she would tease Cloud, hug him, kiss his cheeks and make him blush, making him smile shyly, so pleased with her attention.

Sometimes, she would look at Sephiroth while doing this and wink, like she was aware of Sephiroth’s feelings for Cloud and was mocking him and the jealousy and irritation would be so overwhelming that Sephiroth could throw up.

So he’d taken Cloud’s hand in his, dragging him away from his annoying friends, away from those greedy women, all the way to his room, not stopping no matter how much Cloud struggled, growled and threatened.

It was good that Cloud sometimes forgot just how truly, monstrously strong Sephiroth was because it’d gave him an advantage when he needed it on occasion. Like today.

“What the fuck do you think you’re doing?! Stop, stop it!” said the blond, trying to keep Sephiroth from ripping his shirt open and failing miserably. Sephiroth would have wavered, even stopped if he hadn’t felt the hardness in the blond’s pants ever since he kissed him.

His lips hungrily kissed and licked his neck, biting and sucking until he’d left a trail of marks, signs to make people see, understand that Cloud was Sephiroth’s, that he was out of reach for anyone else. Cloud protested weakly but the constant goosebumps and barely suppressed shivers contradicted his words.

When he reached his nipples, he could feel his own cock grow harder inside his boxers. He’d always been fascinated with the delicate nubs and yearned to taste them with all his being.

So no wasting any more time, he wet his fingers with his saliva and attacked one nipple while he sucked the other into his mouth, nibbling it gently, circling it with his tongue and sucking on it hard, regretting not getting rid of his clothes as he could feel Cloud scratching the back of his shirt. Just thinking of Cloud leaving long marks on his back with his nails made his eyes roll back in need. He didn’t stop alternating between the two heavenly teats until he was satisfied and Cloud was a shivering mess.

“Mr. Cloud’s skin is beautiful and delicious, sweeter than honey and softer than silk,” said Sephiroth, unable to keep those thoughts to himself.

“How can you say that with a straight face? I’m not a girl, you don’t need to say those things to woo me,” protested Cloud, covering his face, unable to hide the deep blush covering his cheeks.

“Does that mean Mr. Cloud will accept me even without any sweet words?” teased the teen, not letting the blond answer and continuing his attack on the body beneath him.

The blond’s lean, pale torso received much the same treatment, being littered with love bites and small bites so Sephiroth could stake his claim on this heavenly body. the need to own him and consume him only increased with each inch of skin he touched, it was unbearable.

Maybe Cloud would be mad at him, maybe he would make fun of him for even thinking he could own a beautiful lone wolf like him but, right now, Sephiroth didn’t care. At least for a while, everyone would know Cloud had submitted to him, had accepted him and chose to belong to him, if only for a night.

Shaking his head to try and get rid of such grim thoughts, he distracted himself with unbuttoning Cloud’s pants after swiftly pulling his belts out of the way. “Sephiroth!” the surprise in the blond’s voice made him feel powerful.

The zipper came down easily, aided by the straining shaft pushing against it and Sephiroth sighed at the sight of the thick length, the tip soaking the soft fabric with precome.

Sephiroth took a moment to gather himself, the fact that one of his many wet dreams was actually happening right in front of him made him dizzy. It was surreal.

He shook himself out of his brief reverie, afraid Cloud would start protesting again, and mouthed the hard cock over the fabric of the underwear, delighting in its heat, feeling it twitch hard against his mouth and he couldn’t help taking a taste of the tip, the tanginess reaching his tongue through the barrier, making him twitch in his own pants.

Sephiroth got rid of his gloves as quickly as he could, all the while lowering Cloud’s boxers with his teeth, holding all of Cloud’s attention and making the man gasp, his gaze burning like the sun on Sephiroth’s skin.

The young warrior took the hard cock in his hands almost reverently, seeing a thick glob of precome drip down from the red tip and following its trail with his tongue until the whole head was inside his mouth. He sucked gently to get as much as of that delectable essence as he could and the body underneath him jerked violently. He couldn’t help but smile around his meal.

“Sephi…roth…” Cloud’s face was flushed a pretty red color, one Sephiroth had never seen before and that possessive part of Sephiroth swelled with pride. Aerith would never make him blush like this, none of them would, this was for Sephiroth’s eyes only. Only because of Sephiroth.

He continued to suck lightly, feeling the shaft grow thicker, harder, the thighs under his arms trembled rhythmically with each action. He kept poking the small, weeping slit over and over, earning a steady stream of that delicious, thick liquid that was so addictive.

“Sto-op, stop… it!” Cloud was trying to push him off but his attempts where very weak and obviously half-hearted. When Sephiroth saw his eyes bright with unshed tears, it made him hesitate for the first time.

“Mr. Cloud,” said the teen, releasing the hot flesh in his mouth, “do you really not want this? Tell me that you truly are not enjoying it, that you absolutely don’t want this with me and I’ll stop.”

Those beautiful ocean eyes looked at him for along moment, full of doubt and lust. Cloud worried his already abused lip, probably considering his options, his breathing heavy and his cheeks a beautiful rosy color. Cloud closed his eyes, like it pained him to admit his defeat, then relaxed and buried his hand in Sephiroth’s hair, not pushing him away, just massaging his scalp lightly.

With renewed confidence, Sephiroth tried to get the whole thing in his mouth. He hadn’t done this before, never having had any contact with a lot of people and much less with someone he’d been this attracted to but he was confident he could do this.

He swiftly tore Cloud’s pants off his legs in one smooth motion, spreading his thighs wide open, caressing the smooth skin he’d admired from afar for far too long then focused his attention on the main prize, slowly licking from Cloud’s perineum, around his heavy balls all the way to the tip of his cock, having to restrict Cloud’s hips from moving too much.

He could feel nails scratching his scalp hard briefly before Cloud caught himself and tried to retrieve his hand but Sephiroth stopped him, enjoying the small flash of pain more than he cared to admit. He was making a mess inside his own underwear but he was too busy with this delicious treat to pay attention to that.

He laved his tongue around Cloud’s cock, wetting it completely, making the glide of his lips and hands easier and feeling not only the shaft jerk hard in his grip, but Cloud’s whole body shudder uncontrollably. Sephiroth had to rub his own hardness to ease the ache in his crotch a bit.

Cloud’s gasps and moans were accompanied with copious amounts of precome, each spurt made Sephiroth eyes roll back and a spurt of his own to soak his own cock. Each taste convinced Sephiroth he could live on just that, if only Cloud would let him.

So Sephiroth licked Cloud’s cock again, tracing each and every vein slowly, feeling them pulse under his tongue, sucking one of his balls inside his mouth, huffing in satisfaction when Cloud’s thighs wrapped around his head and squeezed, enjoying the strength of his grip and the softness of his skin when playing with his other ball yielded the same results.

He spent what felt like an eternity just repeating this pattern, lost in his own bliss, making Cloud slowly go mad with frustration at being pleasured so generously but not enough to push him to the edge. His eyes were bright with unshed tears again and that did nothing but add fuel to the fire of Sephiroth’s desire to drown Cloud in ecstasy.

But that same youth, so full of energy and lust, assured this could not go on forever.

The divine sounds he was drawing out of Cloud; the small, involuntary thrusts and shudders; the exquisite taste of his essence… he couldn’t wait any longer, he needed to have him inside him. So he opened his mouth wide and tried to fit the whole, long cock in his throat but he didn’t position himself correctly and had to retreat quickly, his pharynx constricting hard around the fat head and making him choke a bit.

“Sephi…roth nnnhhh! T-that’s… ennnnough… I can… I can finish myself off…” the hand in his hair spasmed a bit, pushing his head gently.

Sephiroth almost growled. He had made it this far, facing his fear of Cloud’s rejection and the blonde wanted him to stop when they’d just gotten to the best part. Sephiroth would not stop, not now. He just needed to remember how, it had been a while, after all.

The young SOLDIER took a deep breath. Those terrible times where Hojo would shove tubes down his throat with little consideration and threaten him if he so much as hinted at gagging or accidentally damaging them with his teeth would finally pay off.

Finally, he opened his mouth again, relaxing his throat as he’d learned back then, then let the cock slide down until he felt the swollen head almost reach the very back of his throat and his his face was snug against Cloud’s skin.

“Fuck, fuuuuck!” He heard Cloud moan, his hips making small, aborted movements, forcing his cock a bit deeper and making them both graon. His nails dug into his skull again but he didn’t stop this time and the sensation made Sephiroth’s toes curl.

He felt the soft curls at the base of Cloud’s cock brush slightly against the tip of his nose and he buried it on them, nosing the blond hair and delighting in the musky scent. Cloud gasped loudly, his legs spasmed and squeezed around Sephiroth’s head again. The teen did it again, this time keeping his eyes on Cloud’s face and he could see the beautiful sky colored irises come together as Cloud went cross eyed, moaning around the stiff member at the sight earned him a deep, drawn out groan and a huge spurt of precome that he briefly lamented not having all over his tastebuds.

He wanted Cloud to ruin his throat so bad, to shove his cock so deep he couldn’t breathe, to cut his air with the head of his dick until his vision went dark.

He bobbed his head up and down a few times experimentally, just to make sure he wouldn’t choke again and, once he had adjusted his angle and position a bit accordingly, he began his assault.

He swallowed the hard shaft again and again, his movements almost violent, fucking his own face with Cloud’s cock because he knew the blond would never do it even if Sephiroth begged for it. He could feel the back of his throat begin to hurt, his head spinning with how little mercy he was having with himself, not giving himself enough time to breathe properly before forcing his mouth down again. He was straining terribly against his pants, it felt like his cock would rip the fabric if it got any harder.

“Se…phi… roth! Fuck, fuck, fuck! Stop! STOP! What hng are ngh you doing HNG! Oh my f-fucking… SHIT! Ahhh! Ngh ngh ngh! Youuu… you! You’ll h-hurt… yoursssself AH!” Unfortunately, he couldn’t move his hands to relieve himself because he needed to keep Cloud from trying to separate him from his shaft. He missed Cloud’s nails on his head but he couldn’t risk Cloud actually stopping him.

Much too soon for his liking, the cock inside his mouth began throbbing fiercely, the soft balls pressing against his chin drawing up towards him. Cloud was thrashing so much he almost threw Sephiroth off of him and it was only because Sephiroth, even at this age, was physically much stronger than Cloud that he managed to stay in his place. The constant mantra of his name accompanied by sighed pleas and half screams confirmed Cloud was really close.

Sephiroth didn’t want to be cruel but he wasn’t prepared for this heaven to end so soon, so he made a calculated risk, releasing one of Cloud’s hands and squeezed the base of Cloud’s beautiful cock without having to release it from his mouth, preventing him from coming when he was obviously almost right there. His reward was a mouthful of precome and Cloud’s free hand pulling his hair viciously. Sephiroth felt ready to explode.

Cloud let out a frustrated growl that reminded Sephiroth of the wolf crest the man loved so much. That sound sent a shiver down his spine, rasing every hair in his body. Fuck, Sephiroth was so in love with Cloud.

For the next few minutes, he sucked the shaft languidly, slowly working Cloud up to his orgasm again. Once he made sure he was close enough, he started his relentless assault again, making Cloud sob loudly, those unshed tears finally finding their way out and soaking his hair. Cloud seemed like he’d go crazy if this went on for any longer.

“Ohhh f-fuck, I-I cannnnnn’t! Sephi…roth! Pleassse! HNG!”

So, doing as this gorgeous, perfect person asked, he didn’t stop this time. He kept going, his throat feeling more and more irritated, making him moan wantonly. Just once, he wished his healing was like a normal human’s so he could feel the pain long after this night was over.

Soon, he felt the telltale signs again but he just doubled his efforts, drawing an almost pained wail out of Cloud’s magnificent throat.

“Sephiroth, I’m gonna come! I’m coming! Let go, let go! Let go, dammit! Fuck, FUCK! I’m comm…!”

Sephiroth did not let go. He buried that cock as deep as it could go, feeling it spasm violently against the roof of his mouth, the viscous come clogging his trachea, not letting any air in at all. Cloud came so much, for so long, that Sephiroth’s vision turned spotty, he felt delirious from the lack of oxygen and the exquisite sensation of having made Cloud come so hard. Sephiroth, as far as he was concerned, had achieved his life goal and could die a happy man.

He felt two hands push him and he would’ve fought and stayed right where he was if he hadn’t been so weak from air deprivation. He coughed a few times, resting his face against Cloud’s thigh, trying to get his heart back to a normal rhythm and his lungs to stop hurting every time he took a deep breath.

Both men were exhausted, gasping for air and drenched in sweat. It was the best day of Sephiroth’s young life.

Once he regained enough brain function, he quickly took Cloud’s still hard cock, putting the head he loved so much inside his mouth and sucking as much leftover cum as he could. He’d missed most of it as it had gone directly to his throat but he’d get any he could get. Cloud hissed loudly, moaning and pulling the silver locks desperately from the overstimulation.

Once there wasn’t anything left for him, Sephiroth let go of the member and licked his lips, satisfied with the little bit he was able to suck out of it.

Now that the ethereal creature lying in front of him was sated, Sephiroth’s body made it known that he hadn’t been satisfied. The teen pressed his legs together, the pain was almost unbearable at this point but at least he would come quickly, having come incredibly close while Cloud had exploded in his mouth.

Slowly, carefully, he got up on shaky legs, eager to run to the bathroom and take care of his rather dire predicament, making sure to not bother the other man, who almost seemed to have passed out, and started walking unsteadily towards the door.

He couldn’t even take two steps when a hand grabbed his wrist and stopped him in his tracks.

“Sephiroth…” the hoarse voice of his beloved blond dripped with annoyance and, even though Sephiroth didn’t regret anything right now, he recognized that might change very soon.

Quick as a Thundaga, Cloud yanked him back, threw him on the bed and straddled his hips. Nude as he was, the sight only made Sephiroth’s discomfort even worse.

“I told you to stop,” said the blond, opening Sephiroth pants slowly, gripping his twitching, purple colored cock in his calloused hand and pumping it torturously gently so as to not make him come. “I told you to let go,” continued the older man, producing a soft looking string and, without warning, tying it tightly around Sephiroth’s cock, a makeshift cockring, which was not a good sign for him.

“I’ll have to teach you a lesson until you learn to listen to your elders,” said Cloud, his eyes promising hell on earth and his hand caressing underneath Sephiroth’s shirt, pinching a nipple aggressively.

A shiver of fear and anticipation made Sephiroth tremble. He wondered if he’d be alive the next day.
