Unbridled Ownership

Summary:

They were divorced and had no legal rights over each other any longer. But the tension of what it meant to be single hung over them with every intimate encounter.

No matter how much Genesis denied it, he still wanted Sephiroth to himself.

Notes:

Sephesis Week 2026 Day 4: Crisis | Crossroad | The Product of Choices Past

Work Text:

“Fuck—“ Genesis gasped as he tightened around the cock fitting perfectly inside him.

They should have used a condom if only to make the clean up easier, but Sephiroth always made it hard to think that far ahead. What had been meant as a quick visit to grab some things forgotten when he’d moved out had ended against a wall. Then a door. Until crashing into their bed.

Or now, he supposed, Sephiroth’s bed.

Foreplay had been made of rough shoves and backs catching themselves on any surface they could as they came back together to indulge. The simmering emotion still raw between them left sex as the only way to release it. Their clothes were nothing but a trail leading from the front door to the bed. Mouths left purpling marks across bare skin. There were a few wandering tugs as they both grew hard. Fingers slipping into an ass to get him warmed up. Genesis dropping to his knees to suck until Sephiroth was hard enough to ride. Hair gripped even as Sephiroth surrendered the pace to him.

He invited himself to the side table drawer, ripping it open and only pausing a moment before finding the lube. He squeezed the slick liquid directly over that erection before giving it several quick strokes until he was thoroughly coated. It was too much. Too slippery. It didn't matter as Genesis threw him onto the bed, straddled him, and guided that cock against his hole to sink down onto it.

It had only taken a couple minutes to adjust and really begin riding him. A few more for nothing else to matter but enjoying the thrill of getting off.

He rose up, the glide of slick friction leaving him unbearably hard. And then he dropped, letting gravity do the work for him. A heavy groan rattled through his chest as his ex-husband’s cock went deeper into his guts and stretched him open better than any toy he’d been entertaining himself with since the divorce.

Butt plugs. Vibrators. Dildos of various size and shape. None of them satisfied his need quite like the cock Sephiorth had hanging between legs.

Every moan and grunt he got out of the man fueled him even as his thighs burned and hands squeezed into strong tits to take some of the effort. Genesis kept his glassy gaze off of the face filled with too much appreciation and lingering adoration below him, haloed by silver. His eyes closed completely when fingers brushed against his cheek and pushed the hair away from where it stuck to his face.

“Fuck. Fuck.

He could no longer bring himself to move up and down the thick shaft, abs and arms shaking with the effort of keeping himself up while moving. He was out of practice and not as young as he used to be. Back when they were amorous things who could spend all day in bed pleasuring each other until they had no choice but to sleep it off together in warm arms and entangled limbs.

It was a relief when the hips under him rose up sharply, slapping back in deep. He sighed, head falling forward to just feel as he was fucked from below. He was jostled with every thrust preferring to go too far than not far enough, his own stiff cock left untouched.

Large hands landing on his thighs to stroke over hot skin and grip his waist and ass were a bonus, supporting his movements and helping him roll his hips as he rode Sephiroth for all he was worth, meeting every fuck into him.

They slowed, his fingers lifting away from pecs and holding himself with a straight back. When a hand groping his ass caressed its way to his cock, Genesis gasped and only let himself be worked a few times before slapping the touch away.

“You need to resort to that to make me cum for you?"

The challenge was met by a sly smile as Sephiroth clawed into his waist and tugged him down.

Genesis shook with the effort of being forced lower before they were at it again at full speed. He leaned back to rest his hands on the legs behind him and keep himself steady as the cock breached him at a new angle. It rubbed ruthlessly at the front of his walls and thrust hard over his prostate.

There was no telling what noises escaped him in the sparking pleasure milked from him, pound after hard pound. Sephiroth dug the heels of his palms deep into the mattress behind himself to sit up, legs bending for better leverage. Each thrust became a quick slap up, meeting each drop down.

When the bliss of that angle became far too good too soon, that spot inside him well and truly loved, Genesis threw himself forward to slap a hand to the wall above the headboard, faces falling close. Sephiroth glanced down at his lips, and Genesis scoffed before indulging him before the man could withhold thrusts to get what he wanted anyway.

It was a mess, heavy breaths panting and sighing into each wet kiss and lick. When Genesis bit down into a plush bottom lip, he could only moan as their bodies clapped together hard enough for the bed to creak.

“I thought you could do better than this,” Genesis taunted breathlessly against that abused lip. “Or maybe I need to find someone who doesn’t need me to do all the work for them. Someone willing to pin me down and turn me into their personal cocksleeve.” He shoved himself down to take the whole length and pin the man below him in place.

Sephiroth pulled his lips out of another bite and moved to kiss the side of Genesis’ mouth. His jaw. His neck, where he channeled all his arousal into biting back between heavy sucks. He had no qualms about enjoying the soft skin he'd landed on.

Genesis tightened around the cock and gave him a little bounce. The teeth nipping at him scratched the perfect itch. But he wanted more. He needed a chance to let go and be nothing but unthinkingly used. The warmth Sephiroth was searching for wasn’t what this was about.

“I have places to be. Why don’t you stop wasting my time and prove you’re hung for a reason, Sweetheart.”

His tone was mocking, dripping with venom.

It worked.

The wind was knocked out of him as his back hit the bed. He barely had time to smirk before he was manhandled onto his side. That hard flesh inside him slipped out until only the tip spread his hole open for a moment before it popped free and he was left empty and clenching over nothing. It gave him a small chance to breathe.

His wrists were grabbed one after the other and held together by a firm grip wrapping around them. He was knocked onto his stomach, arms pinned above his head. When a hard cock ground against his ass, his own arousal rubbed against the gripping texture of the sheets. He allowed himself to groan into fabric before turning his head to the side to wait in the thick anticipation.

He'd been needing this. Left so untouched after years of being spoiled by it. Quick and heated trysts were all that broke the weeks spent alone in their own beds in separate homes, tiding them over until they inevitably found some excuse to meet up again.

Genesis sighed when Sephiroth's full weight pushed into his wrists so the other hand could pet over the soft skin of his back. His eyes closed when he felt that long silver hair trail over his naked form before a kiss was pressed between his shoulders. And another against the back of his neck.

It was addicting. Too reminiscent of their wedding night when they'd slowed down enough to really enjoy each other. A gentle focus like there could still be some... deeper emotion between them.

It would be easy to find something that wasn't there. Especially as Sephiroth’s demeanor softened, nose tracing the shell of his ear, licking at his earring to give it a gentle tug, and breathing like he was ready to say something that stepped over the line of divorce.

He cut it off before their kind of hook up could turn into something complicated. "Don't you remember where to stick it?"

Sephiroth rarely spoke during sex, preferring to let Genesis guide them while his actions did the talking for him. So, Genesis was caught off guard when his dirty talk was returned with a low chuckle and a deep, "I thought you might need a break. You’re so tight today. Can't find anyone as big as I am to fuck you?”

The implication that he could be sleeping around irked him, though maybe it shouldn't have. They were both technically single. Their kind of relationship wasn't one that had any right to question loyalties. It was both less and more than rivals with benefits. Still, even as a denial was in his throat, his heart went cold, wondering if Sephiroth, in all his free time, perhaps was starting to move on and had been seeing other people.

He covered that spiraling thought up and tried to gather his thoughts enough to spit something back.

Even playing the brute, Sephiroth took a moment to grab a pillow and stuff it under his hips. Genesis snarled even as he let his weight settle into the support and took some time for his muscles to recover. He spread his knees and settled into a deep arch presenting himself for the taking. The grip around his wrists tightened as Sephiroth took hold of himself and pressed back against the offered hole.

Genesis opened his mouth to snap something back in return, biting and cruel, but it only left him vulnerable for a loud moan to rip out of him as Sephiroth sunk back in.

They were reduced to bodies shining with sweat as their most primal scents fogged the room. Genesis let every thrust stab a cry from his dry throat, his cock neglected where it was helplessly rubbed against the pillow. Nothing else mattered but sex. Not the half empty room where his things used to sit. Not the stack of books he'd come over to collect. Not their last encounter’s promise that there wouldn’t be a next time.

The pace Sephiroth set was brutal, bed swaying. Genesis wished they'd used less lube when they'd thought of nothing but joining bodies as urgently as they could. That Genesis had just stuck to giving him a wet suck instead of lubing him up after with quick, demanding tugs. That when he straddled him, sinking down to take him had hurt more.

He wanted the rough friction burning his ass. Wanted to be sore as long as possible so he could curse Sephiroth during the day and touch himself at night when he had nothing but that pain to keep him company. Wanted to make use of his collection of dildos and imagine the soreness rubbing through his ass was from the man behind him rather than a poor silicone substitute. He wanted it to last as long as the love bites spotted over his body would.

His face screwed up in pleasure as that place inside him was stabbed ruthlessly. Again. Again. Again. His hands fisted into any sheets he could manage to claw at and pulled at them a stuttering moan. It turned to a strangled cry as he came.

He forgot to feel sorry for the pillow he made a mess of. The only thing on his mind was how his ass tightened around the cock rolling deep into him again and again. It was overwhelming. Perfect. It made him forget for just a moment about the ring he'd caught sight of in that side table drawer and the empty finger gripping his wrists.

His mind only drifted back into focus when the cock was ripped out of him and a hot, wet rope of cum shot over his back. The room went quiet as Sephiroth finally stopped and dropped into the bed next to him.

Clarity hit hard when their eyes met. The ache of being empty didn’t have the pleasant warmth to it like he had gotten so used to. He felt sticky and couldn’t stand the bodily smell clinging to him. It was childish at best, but feeling Sephiroth's warmth radiating in his direction only left a simmering resentment in his stomach.

Calculating eyes followed him as he rolled off the bed before strong arms could wrap around him and hold him in the afterglow beaming in Sephiroth's face.

He didn't bother with the bathroom, instead ripping a tissue from a box and smearing it against his lower back. It took several tries before he couldn't find anymore, turning instead to gathering his clothes.

“You could stay for lunch,” Sephiroth offered, rolling to his stomach.

Genesis scoffed, not daring to look at the finely cut curves basking in the afternoon light and pillowed by sheets. He shoved his arms unceremoniously into his shirt and pulled it back over all the bruises and claw marks littered over him in such a short time. A button was missing. “You’ve already made me late for an appointment."

He couldn't blame anyone but himself when no other offers were made. It was for the best. One of them had to keep emotion from clouding better judgement. And going by the way Sephiorth watched him move around the room before disappearing into the hall, it had to be him.

Sephiroth appeared by the front door just as he was pulling on his shoes. A pair of sweatpants hung onto his hips and did very little to hide his shape. His arms crossed as he leaned back against the wall to see him out.

There was an opportunity to leave without another word. Grab his stack of books in a defiant show that this really was the last time this sort of thing would happen between them.

But he couldn't help it. Not since Sephiroth had made that comment, so casual and unbothered. Growled into the back of his ear. It was already pissing him off and wouldn't leave him alone until he had an answer. If it had strictly been dirty talk or reflective of what he'd been up to in their time apart.

"Are you?" he demanded.

Sephiroth frowned. "Am I what?"

"Fucking other people."

He cocked his head, the question taking a moment to sink in. When it did, a slow smile spread over his face. His voice, in contrast, was dry and perfectly flat. "Yes. Multiple people."

His stomach dropped. "Who?" The question was out of his mouth before he really decided whether or not he actually wanted to know. If he even had a right to know.

"Too many to count. Nearly every night. They sometimes come over here in groups and watch with erections in hand just to wait for their turn. I engage in coitus with every single one until my unending thirst is quenched."

It was Genesis' turn to frown. The way he spoke was off. "You... what?"

"I've taken out several loans due to the amount of detergent and other supplies I've gone through just keeping this place clean from the sheer number of orgies. It's an unbridled disaster I have no choice but to take part in. My lust too uncontrollable."

Genesis opened his mouth only to come up short. He paused, finally catching the amused glint shining in green eyes.

"Sephiroth."

"All the blood in my brain rushes to my penis. I may as well be the town harlot."

"You're joking."

A smirk. "You should know me well enough that asking is unnecessary. I'm in no hurry to share myself with anyone. The same as it was before we were together."

"So you made me think—"

"I answered a ridiculous notion with an equally ridiculous hypothetical."

His bark was growing bigger than his bite, the relief palpable in his words. "You're a bastard."

Sephiroth's smirked turned softer, never one to twist the knife more than necessary. However, he wasn't stupid and had picked up on the greater implication still left unsaid. "You don't want me to."

Admitting it would sting, but he knew he'd regret it if he didn't say anything and Sephiroth really did begin to traipse around with others. If he denied it now, he really wouldn't have any right to complain later.

"No. I don't." He changed course, even if it was too late to feign any other kind of intent. "I really should have taken your cock in the divorce. You were a virgin the first time we slept together. Doesn't feel like anyone else should reap the benefits of my hard work, does it?"

"No." Sephiroth's gaze traveled down across his body, clothes wrinkled and very appealing. He only spoke again when their eyes met once more. "Would it make you feel better?"

"What?"

"To put your claim on me? Ensure that I couldn't have intercourse with anyone else?"

Genesis looked away, into that familiar house. The layout hadn't changed. Furniture and all the memories that came with it in the same spots they'd always been back when they were inseparable. That simple silver ring came to mind where he'd seen it thrown in a drawer. Legally, it meant nothing. But to him, it still meant quite a bit more than he was willing to say. His pride was too fragile to suggest anything, but if Sephiroth was offering...

"Yes."

"Should I get it?"

It should have never been removed. "Yes."

Sephiroth pushed off the wall and sauntered back towards his bedroom. Genesis' heart beat heavily in his chest as he waited. He heard the bathroom door close on a squeaking hinge that had been there since they'd moved in and water running for a short time. He stayed by the door, patiently waiting.

When Sephiroth returned, he held a black bag in his hand. And he was naked again. An odd choice that made Genesis glance around as though anyone was around to see them. As though he'd missed something.

Sephiroth stepped up to him, focus on that velvet bag with drawstrings, pulling it open. Genesis looked back at his ringless finger before that bag was turned over, and a different kind of silver tumbled into his palm.

He choked. The real meaning behind Sephiroth's offer hit him over the head. A cock cage rested in his hand, held out for him to take.

He plucked the thing up and turned it in his hands. If it had been a long time since they'd separated, it had been even longer since they'd done anything as Dom and sub. That required a certain level of trust that corroded and cracked in the months leading up to their separation.

He wasn't sure if he deserved to have that again. But he wanted it. And Sephiroth wasn't the type to make rash decisions. He took the time to give it a once over to be sure it was still in good condition before looking back at Sephiroth.

The nudity made more sense now. And the running water.

"You're clean?"

A nod.

"You still know where your copy of the key is?"

Another.

"Just the cage. Just to make sure you don't misuse my things."

"Of course."

Genesis nodded dumbly, hands shaking as he stepped in close. It was odd handling his limp cock, no untoward intention to the action. Just gently fitting him into the device, flesh covered by a silver prison and a ring circling his balls. When he was sure it was safe and none of that sensitive skin would get snagged, he clicked it shut and set the lock in place.

His eyes stayed glued to it as he stepped back, pulled back into those days when husband mixed into the role of Master. There was something more satisfying than sex in being trusted like that again. When he tore his gaze away and met Sephiroth's eyes, there was that unabashed adoration again.

He snapped free from whatever that daze was overtaking him and turned back to the door. "I'll be back when I feel like making use of that cock. Until then, only take it out for cleaning. I don't want to find out you've so much as felt yourself up in the shower, hm?"

"What will you do if I have?"

He hadn't thought that far ahead, and he wasn't sure their old rules still held up. Still, he didn't want to leave that expectant expression without something to look forward to. "I suppose I'll have to introduce you to some of the fun new toys I've been collecting."

There wasn't much else to be said. Maybe later. Though that meant he would have to unblock Sephiroth's number again.

He pulled his books back into his arms and opened the door to hurry off to his appointment. At least Angeal would know not to pry into why he was so late to their lunch.

He hesitated one last time, hand on the knob, ready to close it behind himself. One last thing in case he hadn't already been too obvious with his feelings. But if they were going to do some mild play, it was as good of an excuse as anything else could be. The opening he needed.

"You should put your wedding ring back on," he said over his shoulder. "Consider that your day collar until I can find a better one to replace it."

There was no telling how long it would take or if he would bother trying to find something. Not when that ring looked so good on Sephiroth's hand. What were wedding rings if not a socially acceptable collars anyway? Kinky bastards.

The hair on the back of his neck stood on end as a low chuckle followed him outside.

"Yes, Master."
