Sometimes if he’s in the mood, Uki gets very particular about how they will have sex. Last week, Uki asked to be fucked and choked at the same time. A week earlier, he spent an hour playing with Fulgur’s nipples until they were so red and swollen he could not stand the feeling of his shirt on them. Once, Uki begged to be restrained and then taken like a helpless victim. Of course, Fulgur went along with him. In the privacy of their shared apartment, Fulgur doesn’t really have the heart to say no. Not when he can see the glittering anticipation in those odd eyes. Not when the man’s whole face totally lights up when Fulgur gives him a small smile and a nod.
To sum it all up, Uki has a whole plethora of kinks, and Fulgur loves going along with him more than he lets on.
But the thing is, with all the weird requests he’s had, Fulgur thought nothing would surprise him anymore.
Which is kinda stupid of him. That assumption can’t be more wrong. He forgot this was Uki. And Uki can be very, very creative when he wants to be.
“Hn,” Fulgur hisses when Uki twists his right leg a little too fast, and the neural link between his upper and lower thigh gets abruptly disconnected. It doesn’t hurt, not really. But his flesh near the seam can be quite sensitive, as if it’s trying to extend itself down, feel something that doesn’t exist anymore.
“My bad,” Uki says, but his expression is pleased and not at all sorry.
“No, you’re not,” Fulgur says, because there’s nothing else he can do without his arms and legs. He’s sitting on their bed, his back against the headboard. He was going to remove his legs himself, but Uki insisted he wanted to be the one doing it. I’ll take care of you, he said, looking so lovely kneeling there between Fulgur’s legs. So Fulgur sat back and let him remove his clothes and then his arms and then his legs, feeling more exposed and vulnerable than he’d ever felt after the first time he woke up with no feelings in his limbs and a sinking realisation in his heart.
This time, Fulgur shivers when Uki’s hot breath hovers over his navel, his cock already half hard, precum beading at the slit. The other man laughs, light and short. And it makes Fulgur’s heart squeeze at how adorable that sounds.
“Mmm, I’m not,” Uki agrees easily. His hands come to rest on the bases of Fulgur’s thighs, his thumbs rubbing the gnarled flesh soothingly. “Thank you, Fuu Fuu-chan. For letting me do this.”
Fulgur’s lips twitch. He wants to say something in response to that statement, but doesn’t know which word will suffice the whole feelings of for you, anything echoing loudly in his brain so he keeps his mouth shut.
Uki still looks at him like he knows what Fulgur is thinking. Uki has agreed not to use his powers on him, but even without his psychic abilities, he probably still understands Fulgur’s every move anyway.
“Close your eyes, Fuu Fuu-chan.” Uki’s voice is soft, calming. “Let me do this for you. Let go. I’ll take good care of you. Promise.”
Fulgur doesn’t have enough strength to do anything else but comply. He lets darkness descend around him, his mind quieting. He focuses on the presence in front of him, cool fingers caressing his sensitive flesh, inching slowly upwards. Fulgur’s right shoulder jerks when Uki’s fingertips press against his ribs, cataloguing the faint scars. Uki doesn’t pause, doesn’t hesitate; just keeps pressing light touches on Fulgur’s damaged skin. Something wet and a little rough brushes past the seam of flesh and metal on his left shoulder, getting closer to the exposed wires hanging loosely from it. Fulgur shivers. That has to be Uki’s tongue on his stump. He doesn’t open his eyes, but the mental image alone already makes him desperate enough to beg.
“Uki, please,” Fulgur starts, then pauses, not sure how to continue the request. He can feel his cock leaking freely now. It’s driving Fulgur mad that just being touched like this by Uki can do so much to him. His body doesn’t feel like his own anymore. “Please.”
“Shh, shh. It’s okay,” Uki hushes him, sounding amused yet fond. “Don’t you worry, Fuu Fuu-chan. I said I’d take care of you, didn’t I? I promised, didn’t I?”
And Uki did. Uki did. And Fulgur should know how to trust the man more. He nods, feeling breathless and a little frustrated without the use of his arms.
“Good. That’s good, Fuu Fuu-chan. You’re always so good to me.”
And suddenly there’s something prodding at Fulgur’s entrance. His whole body startles at the unexpectedness of it. It’s slicked, and thin, and rubbing on and around Fulgur’s opening. So Uki’s finger then. He relaxes, his skin heating with anticipation.
But the breach doesn’t come. The fingers circle, and rub, and press a little, enough weight to tease and leave Fulgur wanting for more, but not enough to scratch the burning itch buried deep inside him.
Fulgur’s face is hot, and there’s sweat in his hair despite the room being cool and air-conditioned. The fingers play with him, and Fulgur almost can’t take it, almost opens his mouth and tells Uki to get on with it, when there’s something touching his face and then covering his eyes. It’s a blindfold, Fulgur realised with a thrill. And surprisingly, with his sight also taken away, it becomes easier for him to submit. The frustration of pleasure unfulfilled is still there, but mute, in the background. It’s easier now when there’s nothing for him to control. Fulgur completely lets go.
He’s rewarded with a kiss. Uki’s soft lips coax his mouth open, his tongue probing and making Fulgur’s head float a little. Just as he’s thinking that he won’t mind getting kissed by Uki forever, the finger that has been teasing at his rim slides in. Fulgur has been so relaxed and loose that Uki can go in to the knuckle and he barely even feels anything. The finger glides in and out for a few times before pulling out and going in again, but with two of them this time. It draws a long contented sigh from deep within Fulgur’s chest.
“You’re so good, baby,” Uki murmurs, close enough that Fulgur can feel the man’s breath on his swollen lips. Shivering, Fulgur fantasises about having Uki’s cock in his mouth, sucking him until he’s writhing on Fulgur’s tongue, letting Uki use his throat as he chases his climax.
Tasting Uki’s cum on his lips.
“What are you thinking, Fuu Fuu-chan? You tightened up just now.” Uki doesn’t stop scissoring him, probably up to three digits already, and uses another hand to twist Fulgur’s nipple. “Hmm, baby? What got you so tight around me?”
“I wanna, um,” Fulgur licks his lips, trying to concentrate when Uki is trying his absolute best to achieve the opposite. He sighs when Uki’s fingertips are rubbing against that spot inside him, focusing on how to speak. “Wanna blow you.”
“Oh, you do, don’t you?” Uki says against the flesh of his neck, kissing there and probably leaving a mark. He removes his fingers and, with one hand on the back of Fulgur’s neck—Fulgur isn’t sure which—pushes him forward and down. Uki maneuvers him until Fulgur is being laid on his front, his face close enough to Uki’s familiar musk that when he opens his mouth and sticks out a tongue, he’s met with the heat and slick precum of Uki’s dick.
Uki sets a reassuring hand on Fulgur’s head and adjusts the angle a bit to make it easier for him, and guides the rest of him into Fulgur’s waiting mouth. He hums as the head hits the back of his throat, making him gag a little. Uki pulls him up by the nape, allowing a moment’s rest, before gently feeding Fulgur his cock again. Without his arms and legs, there’s nothing he can use to brace himself, to stop Uki from moving. Fulgur floats in the darkness along the rhythm that Uki’s set.
Uki can do anything to him, and Fulgur’s only choice is to accept it. And nothing in his life has ever made Fulgur’s cock this hard before.
Uki’s pace begins to falter, the thighs bracketing his head tensing up, and just when Fulgur expects Uki to shove him down even further, holding Fulgur’s head and releasing inside him, Uki pulls him up and off his dick with an obscene pop.
Fulgur makes a confused noise, his brain incapable of anything more complex. He inadvertently tries to use his hands to push himself closer, but the only thing that gets him is merely a little futile twitch of his shoulders.
“Shh, it’s okay,” Uki shushes him, a hand on Fulgur’s neck to keep him still. “Leave everything to me, baby. I know. It’s okay.”
It takes him a moment to reorient himself and calm down a bit. He realises he’s lying on his back now, Uki’s gentle hands petting his chest and waist and hips. When there’re fingers prodding at his entrance again, Fulgur is already open and slicked enough that it doesn’t register to him during the first few seconds how they feel.
And then it slowly dawns on him. That the fingers inside him are colder and more solid than what he’s used to.
Fulgur might’ve tensed up a bit, because the fingers pause, and a moment later there’s Uki’s hand on his leg, massaging the spot where flesh meets metal. “I’ve always loved your fingers, Fuu Fuu-chan. I want you to love them as much as I do.”
He doesn’t know why, but when he hears that, his body seizes up and Fulgur starts coming. White hot pleasure sizzles through his whole body, leaving tingling sensations in its wake. His mouth is hanging open when his brain reboots, a lingering hint of a scream in his throat.
The fingers—Fulgur’s fingers—are still sliding in and out of his twitching hole, used by Uki to do so, and the thought alone pushes another dribble of cum out of him.
“Nng,” Fulgur’s voice comes out as Uki angles them in deeper. He’s a little sensitive now that he just came, but Fulgur’s refractory period has always been short ever since the surgery, and it seems like Uki is not done with him yet.
“I wanna feel good too,” Uki whines, and Fulgur can almost see the adorable pout on his face. “You’ll help me feel good, right, Fuu Fuu-chan?”
That is all the warning Fulgur gets, before his hardening cock is enveloped by the overwhelming sensations of hot and slippery and tight. If Fulgur hadn’t come a few minutes ago, then this would’ve definitely tipped him over the edge.
And despite being unable to see, Fulgur knows the heat that is sinking onto his cock very well.
Uki moans from on top of him as he settles his weight down onto Fulgur’s pelvis, languidly rotating his hips while still moving Fulgur’s fingers inside him. Fulgur feels like losing his mind.
“Do you like my ass, Fuu Fuu-chan?” Uki pants from above him. Fulgur can tell he’s close, just from how breathless he sounds. He imagines how Uki looks just then, his body shining with sweat, looking like a god, and he wants to tell Uki that of course, he loves it, he loves every part of him. He wants to thank Uki for letting Fulgur worship him like this, but the only things coming out of his mouth are some punched out whimpers. Uki goes on, not sounding like he minds Fulgur’s inability to speak so much, “You look like you adore it, Fuu Fuu-chan. I love your cock too. I almost wish I could clone your cock and stuff you with it. Letting you feel how good it is inside you, you know? So you understand how good you’re making me feel right now.”
And just like that, Fulgur is coming again. He doesn’t know what’s going on anymore, what’s happening to his body. He only knows everything feels good, pleasure so intense it almost feels like pain. Uki milks him through it, until Fulgur feels something land on his stomach and chest, and after when they’re both oversensitive, Uki keeps Fulgur inside him, twisting his hips in a tiny movement that pulls more than a few hisses and moans from their mouths.
Fulgur’s sense of time is slipping. He has no idea what goes on after that and for how long, but eventually Uki slides off him. He’s gone for a moment and Fulgur’s breath quickens. The lack of contact almost freaks Fulgur out but Uki comes back before that can really happen. “Hey, babe, sorry.” Uki kisses his face, calming him down. “I wanna let you see something, so I’ll take off the blindfold, okay?”
Uki has to repeat the question again before Fulgur manages a small nod.
The light is dim when Fulgur opens his eyes, but he still has to blink a few times to let his eyes adjust to the sudden change. Uki is lying next to him now, his head pillowed on Fulgur’s shoulder. It takes Fulgur a few more seconds to notice that he’s holding his phone in front of them.
On the screen is a picture of Fulgur.
He looks… ruined. There are deep red marks peppering all over his whole body, especially around his neck and chest. His lips are swollen, his cheeks flushed, and his hair is a mess. There’s cum painting his abs. And Fulgur’s own hand is still there in between his legs. He looks so filthy, and helpless, and it’s very, very hot.
“You’re very beautiful, Fuu Fuu-chan,” Uki whispers into his throat, tasting the skin there again, and Fulgur can’t take his eyes away from the picture. “You don’t know how tempted I am to just leave you here like this, vulnerable and exposed and ready to be used. I’d leave you here on the bed, stuffed full by your own fingers, or maybe a hand, while I stream gods know what in the next room. You’d be left here, full but without any release, with no way for you to do anything without me here. Maybe I’d end the stream early if you beg loud enough, hmm? I’d come back and yank the hand out and fuck you onto my cock like a fleshlight. You’d like that, wouldn’t you, Fuu Fuu-chan? Being used like that? You’d let me do that, right?”
Fulgur is keening now. He doesn’t care how sensitive he is, but his hole is twitching and he needs Uki inside. Please, please. Fulgur can’t think anymore. He needs Uki’s cock. He can’t.
“Shh, baby, I’ve got you,” Uki is in front of him now, looking down at him with adoration in his eyes.
Fulgur doesn’t even notice when Uki pulls the fingers out.
“I said I’d take care of you, didn’t I?”
And Uki does. When he enters Fulgur, there’s not anymore finesse left in his movement. He sets a quick pace, roughly aiming for Fulgur’s prostate and chasing after his own orgasm. Uki comes inside him, filling him up until Fulgur’s shaking and finally passes out.
***
When Fulgur blinks his eyes open again, it’s already late morning the next day judging from the sharp beam of light slipping in through the curtains. He tries to wiggle, but quickly realises that every part of him aches and he’s still without his arms and legs. He’s clean, however, he discovers when he inhales deeply. Uki must’ve washed him afterwards yesterday. And he’s being hugged like he’s Uki’s personal body pillow, so even if he could, he wouldn’t have the heart to move anywhere anyway.
All things considered, his body is sore but comfortable, surrounded by Uki’s warmth, both of them buried snugly underneath the cover.
Fulgur closes his eyes and decides to sleep for a little bit longer.
