Uki thought he wasn’t the possessive type.
All things considered, with him and Fulgur being in an open relationship, and Uki taking advantage of it most of all, he felt like he wasn’t allowed to be possessive. It made no sense if he was. Him, Uki Violeta, the man constantly being drowned in adoration and sexual favors, being possessive? No, it wasn’t possible.
That was, at least, until he saw his boyfriend walk in with a hickey on his neck.
Fulgur had been out celebrating with some friends in the company, apparently drinking. Uki had had a long day, so he opted to stay home on this one occasion, cuddling up at home with a nice movie playing on his laptop instead. When he heard the door open, he looked over to see Fulgur waving goodbye to the designated driver, before shutting the door and sauntering his way over to Uki with a slightly tipsy grin.
“Uki, Uki, Daisuki.” Fulgur called for his boyfriend giddily. Uki stayed on the couch, watching his slightly inebriated cyborg clatter and clamor his way through their shared apartment. Uki made space for him, his hand reaching down and patting the zone next to him.
Fulgur sat, and that was when Uki noticed it.
A fat, purple, blooming bruise, right on the tipsy man’s neck.
Uki’s eyes widened. The two had talked about boundaries before. Fulgur let Uki mess around with any handsome man he wanted, and Uki allowed Fulgur to do the same, albeit he never thought it would actually happen. The most that he had seen was Fulgur flirting with his friends from Niji. And even then, it was never anything close to what Uki had done.
So it was a bit staggering to see Fulgur with evidence of fooling around.
“How was the get-together? The… what was it again?” Uki asked, trying to distract himself from staring at the glaringly obvious bruise on his lover’s neck.
“Hm? Oh, yeah, ‘s nice. Missed you though.” Fulgur leaned his head onto Uki’s shoulder, humming in relaxation. Fulgur was always a loving drunk, but not a horny drunk. Uki knew that, so that meant someone else probably instigated the naughty action.
Speaking of naughty action.
A certain cyborg was now nuzzled comfortably in his neck, taking soft sniffs as he draped his arms lazily over his boyfriend.
“You smell good.” He giggled at his own comment. Just how gone was Fulgur?
“Thanks, baby.” Uki wrapped his arm around, feeling the cyborg’s mechanical spinal cord up and down. Every metallic ridge and every hard corner, Uki felt it through the shirt. It’s something he loved about Fulgur- when he leaned down, his mechanical spine would show up better. Uki found it adorable.
The thought of someone else looking at his Fuu-Fuu-Chan with the same eyes as Uki did made his blood warm.
“So, Fuu-Fuu-Chan.” Uki decided to address it now before he let it stupor into a huge argument later. “Who gave you this… lovely hickey, hm?” He asked, picking up Fulgur’s chin and tilting it to the side.
“Hm? Oh. That? Alban got a bit too handsy with me and said he wanted to leave a bite.” Alban . I told that bitch to stay away from my man. “Why?”
The question caught Uki off guard. Why did he care so much? Usually when Alban and Fulgur flirted in front of him, Uki guarded Fulgur with his life. It was all an act, all for show. If his boyfriend really did want to go for the catboy, he would let him.
Fulgur’s eyes narrowed as he sat up straight. He leaned in close to Uki, smirking. Uki hated that smirk. He wanted to wipe that smirk straight off of Fulgur’s face.
“Are you… jealous, Uki?”
The way Fulgur’s silver eyes stared through Uki’s own made him shiver. Fulgur was right, this burning feeling inside of him was most likely jealousy. Jealousy? Him? He’s not supposed to be the jealous type! Not when his Fuu-Fuu-Chan let him play with so many boys, and- he couldn’t be jealous! It was impossible!
Fulgur’s deep laugh brought Uki back to reality.
“My little Uki’s a little jealous, is he?” A metallic hand tucked a few strands of hair out of Uki’s eyes. “Wants to claim me as his? And only his?” The teasing tone Fulgur used was one Uki heard very little of when they were alone. Usually, it was reserved for stream time, other than that, Fulgur was a very shy lover.
So seeing this side of him made Uki’s pants quite a bit tighter.
Grabbing onto the front of the other man’s shirt, Uki gave no room to respond as he smashed their lips together. It was messy, and Fulgur tasted faintly of alcohol, but Uki didn’t mind. This teasing was driving him up a wall. If he didn’t fuck Fulgur immediately, he was pretty sure he was going to go insane.
Fulgur let out a surprised sound, but quickly melted into the embrace. It was hot and messy, nothing like what it would be like if the cyborg was the one instigating. But in that moment, Uki was the leader. Uki called the shots. And Uki wanted all of Fulgur, no matter how messy it got.
Fulgur opened his mouth, allowing Uki to quickly shove his tongue down the other’s throat. The moan Fulgur let out as he did was downright sinful and Uki absolutely adored it. But he had to breathe. The tightness in his chest was getting to him, and he felt like passing out in his boyfriend’s arms wouldn’t be a very sexy thing to do.
Pulling away from Fulgur, Uki absorbed the sight before him like he was a sponge. Fulgur’s eyes were half lidded and his pupils were blown out, along with his lips slightly parted, with saliva running down them. He looked like a wreck and Uki only wanted to destroy him more.
“Get up.” Uki demanded, pushing himself off the couch, dragging Fulgur by the front of his shirt to their bedroom. Fulgur grinned. He knew what was coming next.
Uki kicked open the door with a grunt, tossing his (clearly stronger) boyfriend onto their bed with a slight struggle. Uki wasn’t known for his physical strength, after all. He was more well versed in his flexibility, (which Fulgur liked to exploit, a lot ), so his muscles were always less defined than most of his genmates. It wasn’t his fault that he had a more buff boyfriend who would usually do most of the work for him.
But now, here was said boyfriend, splayed on their bed with a coy expression.
“Look at you, Fuu-Fuu-Chan.” Uki growled from where he stood, starting to take off his buckles. “You look so proud of yourself. Huh? Is that it, Fuu-Fuu-Chan? Are you proud you got this reaction from me?” Uki’s eyes were shrouded in shadows, and it made Fulgur even more excited.
“Would it be wrong to say yes?” The sly bastard asked.
Uki chuckled, ripping his jacket over his head and tossing it to the side.
“Wrong answer, bitch.”
Pouncing onto the bed, legs locked, arms and fingers tangled in hair. Metallic fingers grabbed at Uki’s scalp while Uki’s fingers ran up the back of Fulgur’s neck. Their lips were inseparable, it was almost something pornographic to view. Fulgur moaned into Uki’s harshness, keening into every moment with ecstasy.
Uki pulled from the sloppy make out and moved to the cyborg’s neck. The sensitive, pale, ready-for-marking neck. Uki could barely contain himself as he latched onto the pale skin, kissing and licking every inch he could get his lips to reach. He needed to blot out any memory of Alban kissing Fulgur, and replace it with him. He needed to remind Fulgur just who he belonged to, because at the end of the day, Fulgur was Uki’s.
And Uki intended to make that well known.
Fulgur gasped as Uki bit harshly down on one spot, suckling sweetly. It was obviou was Uki’s goal here was. He wanted to leave marks. He wanted to claim Fulgur, and Fulgur was completely okay with that. He purred into the moment, his mechanical hands running up down Uki’s body as the psychic littered him with bruises.
Fulgur groaned as Uki came back up with a ‘pop’, his heterochromatic eyes boring deep into Fulgur’s. Fulgur felt like he could get lost in them. Uki grinned.
“Hey. I can read your mind, you know.” Uki mentioned.
“Oh, can you? I wasn’t aware of this.” Fulgur smugly replied.
“I can tell you what you’re thinking of right now, baby.” Uki mumbled. “And yes, I will suck your fat cock for you. Right before I stuff you in me and fuck you until the sun rises.”
Fulgur choked. Uki’s simple way of saying such dirty things made his body very quickly aware of how sensitive he was. The blood in his body was switching from his face to his cock, and Uki grinned as he watched it all go down. With no limbs to travel through, it made a quick trip, and Uki could feel Fulgur poking at his ass.
“Hm? You seem to like that idea, Fuu-Fuu-Chan.” The comment was almost a whisper to the cyborg, who grunted quietly. He nodded, swallowing the excess saliva in his mouth.
“Anything with you sounds amazing, Uki.” He shot right back. This sly bitch.
Uki smiled. Fulgur melted.
“Then why are you still stuck in your stuffy jacket, huh?” Uki questioned, tugging at the fabric still keeping the cyborg protected from the cold. “It’s not fair that I’m shirtless and you’re not. Come on, Fuu-Fuu. Let me see those fat tits you’ve been working out just for me to see.” Uki was nearly drooling as he watched Fulgur sit up with an amused smirk, beginning to strip.
The movements were quick and obviously rushed, and a bit silly, in Uki’s opinion. At one moment, Fulgur’s hand got stuck in a fold of his jacket so he had to shake his hand around like he was a bird trying to take flight. Uki snickered for a moment, but simply began to strip himself once more.
Uki stood in only his boxers, and Fulgur, his pants. Uki rolled his eyes, mumbling something about Fulgur being a slow ass, to which Fulgur replied with a cocky smirk once more.
“Why don’t you come help speed up the process, Uki-Suki?”
Uki growled a bit in Fulgur’s direction, grabbing at the other’s belt with a grumble. Fulgur leaned back and let Uki do most of the work, letting the comfy sheets comfort him into a calm state of bliss.
That was, until his pants and boxers were ripped off in one fell swoop.
The cold air barraged the bottom of his body, his sensitive cock standing straight up with pride. He hissed as he felt the chill in the room, to which Uki hummed.
“Something, something, warming you up now.”
Fulgur didn't have a moment to respond before warm lips wrapped around his head. He gasped at the wet warmth, eyes fluttering shut as mechanical hands made their way to hold Uki’s head. His own thoughts were being drowned out in the idea that Uki could make him feel so good, with only his mouth, too. It was something ethereal he swore.
Uki bobbed his head up and down slowly, almost too slowly. He wanted to tease Fulgur, only a bit. His tongue licked up the underside, then made its way to the tip, licking up and all around just to hear Fulgur let out those moans he wanted to hear so badly. And Fulgur relented.
How could he not? With Uki bobbing and licking his dick like it was a popsicle Uki was devouring, Fulgur couldn’t resist letting out a few grunts and groans to egg the man on. The heterochromatic eyes stared deeply into Fulgur’s being, as if he was reading his very soul just to learn how to make him feel good.
Uki popped off Fulgur’s tip, wiping the trail of saliva that connected them together. Fulgur grunted a bit, but Uki shot him a look that shut him right up.
“I have to prepare myself, so don’t look so disappointed.” He shot, moving to their bedside table and grabbing the well-loved bottle of lube from their drawer. Uki popped it open, shuffled out of his boxers, and got back onto the bed on his knees, facing Fulgur.
“Fuu-Fuu…” Uki whined as he lathered his fingers with the slippery lube. “Can you talk dirty to me while I do this?” Fulgur only nodded, placing a cool hand on Uki’s cheek. Uki rubbed himself into his hand as he started to stretch himself out.
“Uki… you always look so gorgeous for me when you stretch yourself out for me.” Fulgur began. “With your chest to the mattress, and I get a perfect view of your fingers going in your ass… Makes me want to fuck you even more.” Uki hummed at the words, stretching his fingers slightly to help adjust.
“There we are. That’s it. In, out, just like that. You know, there’s no rush, baby. I can stay here all night, just watching you, fingering yourself and pleasuring yourself.” Uki gasped, brows furrowing at the cyborg.
“I know I said to talk dirty to me, but you are way too good at this.” Uki grumbled, pulling his fingers out of himself and sitting up straight. “Okay, get your cock in me before I sit on it already.” Some days, Uki was more seductive and caring when it came to dirty talk. Today was not one of them. He wanted Fulgur, now.
Fulgur wasted very little time hoisting himself up, getting to his knees and pulling himself closer to Uki. Uki purred, hooking a finger seductively, the gesture making Fulgur’s willpower crack. Fulgur grabbed Uki’s hips, lining himself up with his prepped hole, disregarding all worry and smirking a bit next to Uki’s ear.
“You ready, babe?”
“Fuck me, Fuu-Fuu.”
Fulgur immediately thrusted into Uki, letting out a long groan as he felt the psychic’s warm hole, right around his cock. Uki whined, wrapping his arms around the neck of the cyborg. He was thankful for the position they were in- chest to chest always allowed for more intimacy between the two.
Fulgur licked a long stripe against Uki’s collar, his hands settling on the man’s hips to encourage him to sit still. Uki grunted- he wanted movement, and he wanted it now. So, instead of listening to Fulgur’s previous suggestion, he simply placed his hand on the cyborg’s chest and shoved him into the mattress, straddling the man with a smirk.
“Since you won’t fuck me,” Uki huffed out as he raised his hips. “I guess I’ll just fuck you. ”
Fulgur’s mouth dropped open to say something, but was cut off with a strained moan as Uki dropped his hips onto his cock again. Uki let out a sweet pant, holding his hands on Fulgur’s chest to brace himself. Every time he brought his hips up and down, there was a wet slap, and a pair of loud moans echoed in the room.
“Do you like this, Uki?” Fulgur choked out between moans and half-assed thrusts into the air. “Like claiming me as yours? L-like fucking me into oblivion?”
“You’re mine, Fuu-Fuu-Chan.” Uki nearly growled. Fulgur met eyes with the psychic, and saw Uki lick his lips. “All. Mine.”
It was fucking hot.
“All yours, Uki.” Fulgur moaned as he clutched the boy’s hips for some stability. He felt like if he didn’t, he was going to float away. “All yours. Please, keep going like that.”
More wet slaps came between the two men. Uki held his mouth open, fully panting from his exercise of fucking the poor cyborg into the sheets. Fulgur looked blissed out, but could see Uki was pushing himself a bit too far. He gestured for the other to come closer- face to face- and Uki followed.
When he did, Fulgur locked their lips together and began thrusting into the psychic relentlessly. His pace was hard and fast, and Uki was caught off guard. Way off guard. So off guard, in fact, that he found himself falling into the crook of Fulgur’s neck, letting out a stream of obscene moans and curses.
Fulgur had never felt more proud of himself.
Catching Uki off guard was always a feat- he was literally a psychic, after all. But every so often, Fulgur managed to do it, and it ended up with Uki melting into pleasure. He would pant, beg, moan, and practically turn into putty in Fulgur’s hands. It was a challenge, but the payoff was so worth it.
After a few minutes of Fulgur bucking his hips into Uki, Uki finally managed to choke out a full sentence. “F-Fuu-Fuu,” he panted, and Fulgur groaned at the warm breath on his neck. “‘M close. So close.”
“Oh yeah, Uki baby?” Fulgur grunted as he continued to piston his hips at a ruthless pace, tumbling Uki further down into his pleasure-filled haze. “Then do it. Go on, cum for me. Mark me, Uki baby. Claim me as yours.”
Uki swore he saw white.
The psychic let out a long, ecstasy-filled moan as his orgasm washed over his body, cum splattering over his and Fulgur’s chests. But Fulgur didn’t stop. He gripped Uki’s hips tighter, nestling his cock deep into the overstimulated man.
“Just a bit more, Uki. I’m so close, just some more.” Fulgur’s voice was comforting, despite the circumstances. He continued to thrust, chasing his own high, and all Uki could do was take it. He leaned into the cyborg’s embrace, letting out cries of pleasure as Fulgur fucked him through his high.
It took only a few more thrusts for Fulgur to completely empty himself inside Uki, receiving a happy moan from the psychic as the two slowly came down from their climaxes.
Loud pants and the scent of sex filled the room.
Uki pulled himself off of Fulgur slowly, making sure not to leak himself onto the sheets as he made his way towards the bathroom. Fulgur whined as he was left alone in the bed, to which Uki giggled.
Fulgur could hear the sound of rushing water, and Uki called out to him.
“Come in here and help me clean up. I can’t have my boyfriend smelling like sex and sweat as he goes into work, now can I?”
Fulgur smiled as he peeled himself out of the two’s bed, stumbling his way to the bathroom. His legs were still a little shaky- he always had that trouble after a hard orgasm. Luckily, Uki noticed, holding out a hand from the tub, coaxing him to come in.
“Come on then, Fuu-Fuu-Chan. Sit behind me, let’s take a bath together.”
How could Fulgur say no to Uki’s adorably soft face?
Fulgur nodded as he slipped into the bath, his chest meeting Uki’s back as he leaned against the psychic. Uki smiled, his hand reaching up and tussling with his boyfriend’s hair.
“Man,” Fulgur mumbled, a bit gone in his afterglow. “If I knew this would’ve happened, I would’ve asked Alban to put a fake bruise on me ages ago.”
Uki stopped.
“What.”
“Oh, yeah. It’s not real, Uki.” Fulgur revealed with very little fanfare. “It’s all just makeup.”
Uki spun around so fast some water spilled out of the tub. He dunked his hand into the water, before rubbing it against the ‘bruise’ on Fulgur’s neck.
It smudged.
It fucking smudged.
“You… fucking… bitch.” Uki cursed, letting out a small chuckle in disbelief. He covered his face with his hands, leaning into Fulgur’s chest, who simply held the boy there with no worries.
“Aww, come on, Uki! It was so hot seeing you be all possessive. I really enjoyed it, honest.” Fulgur soothed, rubbing circles into the psychic’s back. Uki only groaned, embarrassed to see himself so worked up by a little bit of makeup.
“Whose idea was it?” He asked, his tone dry.
“Mine. Sonny had brought up how on streams Alban acted clingy, when he wasn’t in real life. That made me start wondering if you were the same, considering, you know…” Fulgur gestured with his hands a bit, trying to find the right words. “… the whole ‘yandere’ thing?”
Uki blushed and whined, but Fulgur continued speaking.
“I asked Alban for a bit of help on the actual ‘bruising’ part- but it was all my plan from the start. I just wanted to see how you would react, Uki baby.” Cradling the boy in his arms, Fulgur kissed Uki’s forehead softly.
Uki sighed, finally looking up and meeting eyes with the boy.
“It’s not… bad, right? Me being a bit possessive? I know we talked about how you can fool around with others, but I-“
“Uki.” Fulgur cut him off, placing a finger on his lips. “It’s completely okay. I’m not going anywhere. I’ve only got eyes for you, babe.”
Uki smiled under the robotic finger, moving it aside and leaning up to lock lips with the part-robot man.
Who knew all it took was a little eyeshadow to get Uki so riled up?
