Work Text:
Ryusui has desire. No matter big or small, Ryusui always wants something. He honed his skills and broadened his networks, and does everything he can so that he can achieve anything. Ryusui will always desire something and he will always do everything to get what he wants.
Coincidentally, Gen loves to test limits. It's not only fun, but also calculative. Once he found out to what extent someone or something can go, he would be able to navigate his interaction with them. It's not malice no matter what other said, it's just math. The more challenging it is to find the limit, the more exhilarating it is for him.
So really, it's only natural for Gen to have an urge to test Ryusui's limit.
Ryusui loves beating any challenge to get what he wants, and Gen loves to test any limit.
They are so compatible in a sense that beyond their own sanity.
Then again, Gen never thinks this as a bad thing.
Not when it leads to him having Ryusui drooling over him, panting and moaning in each stroke from his hands.
"You are really something else, Ryusui-chan," Gen sings to Ryusui's ear, relishing the feeling of Ryusui's hot breath on the crook of his neck. His hands stroke up and down again, gaining another muffled moan from the other man. "Really, really something else."
He pulls his hands away, along with the relief sigh from Ryusui. His wet hands move to the shoulder of the man who has been leaning to him for the last fifteen minutes, and he pushes him a little to take a good look at him.
The head is still bowing without strength, so Gen lifts it up a little to see how his masterpiece has turned out. Ryusui's watering eyes are not focusing on Gen at all, they look like they are about to roll all the way back. The gag is still stuck in his mouth, a tape holding Gen's tie in place making sure it's not slipping out even with all the moaning and grunting. His face is so, so red and wet, with his hair getting all over the place, oh, what a scenery. Ryusui is breathing heavily with the way his nose keeps taking in air desperately.
Once again Gen is so grateful lightbulb is not that hard to make in this stone era that he can appreciate the artwork in front of him even in the middle of the night.
"You look fantastic!" Gen compliments him, not that he is sure if Ryusui can hear him. So, he pulls him in again, putting his man into his embrace tenderly. He pats Ryusui's back and strokes the back of his head gently. "You're so amazing, Ryusui-chan! You hold on for more than an hour!"
Ryusui probably tries to say something judging by the amount of noises he is making through his gagged mouth, and Gen answers happily by nudging the chain on Ryusui's chest, making the blond jerks in surprise as the clamps pull his nipples along.
It is probably a screaming sound, but Gen can never be so sure, so he pulls again to listen more carefully. The body jerks again, arching back like Ryusui is trying to escape. Oh, so it is a scream.
"You still have a lot of energy, don cha?" Gen praises him again because he knows how much Ryusui loves praise.
True to that, Ryusui writhes in trembling breath. Magnificent. Gen suspects he would push Gen away if he has the means to do it. Fortunately, they already foreseen that and put Ryusui in restraints. It's not really that luxurious or anything. Just some ropes with some knots. The bound lines around his chest and upper arms with his hands fold to his back. Another ropes on each remaining limbs, making sure that each upper and bottom legs are connected to each other so that Ryusui can't use them to run away. Nothing really complicated but it works. They even don't put anything between his legs so that Ryusui can let his junk open widely for Gen to tease.
It is fun, really, teasing that penis of Ryusui with anything Gen can think of for the entire hour. He used his mouth, his feet, his own penis, his hands, some wet fabric, and Ryusui always managed to hold his ground. Sure there is some leaked cum there and there, but Ryusui expertly avoided getting himself any orgasm. Gen even purposely stroked longer than his previous edging, but Ryusui never slipped out.
What a very hardworking man.
"Let's give your tiny captain a break hm?" Gen says, wiping the still rolling tears from Ryusui's face. Ryusui's bottom does deserve a break, because it won't be fun if it loses its spark when it is Gen turn to put it in him. What a very thoughtful partner he becomes, and he wants Ryusui to feel everything all over so Gen thinks it's time to free the chest. He yanks the chain with much strength that it takes the clamps off from Ryusui's nipples immediately.
Of course it is accompanied by Ryusui's muffled scream which is what Gen is trying to do, it makes him so proud of himself.
Ryusui is arching backward again, but Gen's arm is holding him steady, making sure he stay sitting upright on their futon. The washing day will not be fun but that's a thought for later. Gen throws the chain aside and focuses on the red, hard nipples in front of him. The entire naked body of Ryusui is full of sweat, his nipples are not the exception. Gen almost hopes he can taste milk when he starts licking one of them but well sometimes you can't really have everything you wanted. But at least he makes Ryusui tremble and whimper, and that feels good too.
Maybe Gen needs to take off his inner clothing now because he himself is sweating so much and the fabric is sticking to his skin uncomfortably, but it's really uplifting to let Ryusui be the only one naked so Gen will do it later.
For now, he is busy eating Ryusui's seductive nipple while his free hand is playing with the other one. Ryusui's moaning behind his gag is so addicting and enticing it almost makes Gen want to rip off the tape to let Ryusui make as much noise as he wants, but patience.
He glances down, seeing how the guy at the bottom is supposed to rest, but it is still pulsating like crazy. Gen laughs on Ryusui's chest. "You are really greedy, Ryusui-chan~" he hums to him and flicks the nipple in his hand.
Ryusui writhes again with his pleasuring noise.
Gen starts raining pecks on Ryusui's chest, licking them in between, and moves up to his collarbone, to his neck, then to his cheeks. Ryusui never stops moaning at each contact.
It's really captivating.
"Good," Gen breathes at him. He pulls Ryusui in, letting him put his head and weight on his shoulder while Gen's hands travel down to the bound on the legs. It's really easy to untie all the knots, really, so it doesn't take a long time for Gen to free Ryusui's legs from their restraints. Ryusui lets out a very deep sigh. Oops, they might tie it too tight, Gen takes a note to loosen it a little next time. Gen breaths, then, he takes off his own bottom wears, a short pant and an underwear, in one swift move. He is still wearing his inner shirt so Ryusui is still the naked one in this. Hah.
Gen embraces Ryusui again, trapping his body in his hug, and flops down to the futon. There is an oomps noise from Ryusui, probably not ready to be moved like that, but Gen just chuckles. They take a few seconds to breathe, fair enough.
"You are crushing me down, Ryusui-chan," Gen reminds him. "That's not a very nice thing to do," he says sugary sweet.
Ryusui flinches a little, and with the weak strength he still has, he anchors his weight on his trembling knees with his head still searching for support from Gen's shoulder. Gen wonders if Ryusui knows what he is doing, with his face still buried on his neck, but the way he positions his knees against his inner thighs makes Gen need to spread his legs open. If Ryusui does it on purpose to be seductive then it's totally working.
"Just wait a little," Gen whispers to him. "Can you do that for me?"
Ryusui is trembling, it's definitely taking a lot of strength and focus for him to stay in his position, and he nods with a very tiny muffled voice.
Gen kisses Ryusui's head (whatever part he can reach) to thank him. His hand searches around the side for the condom and lubricant he has prepared. They are placed nicely on a tray basket so it is so easy for Gen to reach. He hums with joy as he works with the condom and lubricant. Ryusui has done a very good job so Gen can help him this much. It takes a little time to put the condom correctly and Ryusui's grunts are not helping at all. Gen rolls his eyes when Ryusui moans again as Gen coaxes the lubricant on his protected dick. What a needy man. Gen leaves Ryusui's bottom alone to take care of his. With a little bit of effort and grunt, he takes off the plug that keeps his hole open since their section started. He sets it aside and breathes.
"Ryusui-chan," Gen calls to him, which is answered with a very whiny grunt. "Do you want it?" he asks.
The head on his shoulder is nodding a few times in the span of a few seconds, tickling Gen into tiny giggles.
"Okay, okay, clingy asshole," Gen assures him. His hand reaches down, nudging the coaxed penis seductively. "Fuck me then."
Gen can feel the shaking of Ryusui's entire body. He must be so exhausted and near collapsing, but this is Nanami Ryusui who always gets what he wants, and Gen is not surprised a slightest when the man on him starts moving his hips. It will be impossible for Ryusui to find his entrance so Gen is willing to help him at least that. He guides Ryusui's not so little dick into the rim of his hole, and Ryusui the greedy bastard that he is immediately thrust in once he finds the entrance.
Scream comes out from Gen's throat right away. The pulsating penis of Ryusui is entering his hole half way and Gen almost thinks his hole is going to tear apart. His hole was only stayed open by the plug and Ryusui's penis is at its most hard and big state for all the edging, so it's painful as it's pleasuring.
Knows that he hasn't gotten in fully, Ryusui pulls away a little and thrust again, sending Gen into another yelp. Gen's arms warp around Ryusui's neck, seeking for support as Ryusui keeps pounding him again and again. The tight hole opens more, the pains turn into more pleasure, and the scream turns into moan. Gen's loud moan and Ryusui's muffled one fill the room with that lewd noise of pounding.
Gen didn't expect Ryusui to hold on that long, he thought he would reach his limit by a few first thrusts, but he was wrong. Ryusui, with that heavy breath and obvious exhaustion, keeps moving again and again and Gen's arms warp even tighter around Ryusui.
It is so intense that Gen's own penis is already hard so much. Ryusui's dick is getting faster and feeling bigger the more time passes and it's both impressive and terrifying.
Just how much strength does this person has?
Gen can't think and his legs start spamming through the stimulation. He moans so much that he is tearing up and drooling and it just... it is just so amazing.
He pulls Ryusui's deeper into his embrace when the cum bursts inside the condom, pushing the wall of his hole even wider.
Not even a second later, Ryusui's body gives away and drops on top of Gen without any remaining strength. Gen is not letting go of his hold of Ryusui even if the man heavier than him is staying still on his chest. The weight does not bother him, it is the fact that Ryusui had an orgasm before him. Gen isn't even near his climax, and Ryusui has already lost all his strength.
But again, Ryusui managed to stay upright longer than what Gen had thought so probably he is due of some helping hand. Gen pushes Ryusui to his side, doing it as he pleases to lay Ryusui on his back. His hole is already free from the cum filled condomized dick, and he wants it back as soon as possible. He ignores Ryusui's muffled, weak writhes as he climbs up to him, putting himself on top of Ryusui. He does not say anything because he does not want to waste more time, and then he puts the dick back into his. He slides down to Ryusui's body, taking in the still hard penis into his entire hole and relishing the fill up space in him once again.
Ryusui makes a noise that sounds so similar to a sobs.
"I know," Gen says to him, lifting himself up a little to adjust himself. "You can never get enough of me, don't you, Ryusui-chan?" and he slams his hips down in quick motion.
He bounces on Ryusui excitedly, up and down again and again, feeling how the penis inside him is getting harder again like it is even possible. He adjusts the position so that his bounce makes the tip hit the right spot and Gen moans as much as he want. The hips under him is not staying still, because Ryusui somehow still has a little strength to follow the pace.
Ah, what a wonderful experience to be desired by someone as greedy as Ryusui.
It makes Gen so ecstatic that he only takes a few breaths after his hard earned orgasm to start bouncing again on Ryusui, who in exchange is now sobbing all out. The hips of him is still moving along though, so it's really a very amazing day for that limit test.
Really, Gen smiles in delight seeing how his second orgasm sends another lines of cums on Ryusui's stomach, painting that sweaty torso with the juice of him. Truly a work of art.
Slowly Gen lets go the dick that cum inside him three times today. The condom is now stretching too much that it makes Gen laugh. He takes it off and wants to show it off to Ryusui for a good laugh, but Ryusui is too busy slowing down his breathing and sobbing so Gen just shrugs and sets it aside, maybe next time. Gen takes a very deep breath and stares down at the unmoving Ryusui. He watches as the chest goes up and down, from fast to slower and slower. They both try to even their breathing and Gen thinks this is extremely hot.
But then again, it is weird to be the only one who talks, so Gen bends down and rips off the tape sealing Ryusui's mouth. He digs into the tie of his that stays in Ryusui's mouth the entire time and takes it out carefully, not wanting to gag Ryusui worse. The moment it is off, Ryusui gaps for air.
"Beautiful," Gen comments softly as he brushes away the strains of hair from Ryusui's face.
Ryusui is now peering up at him, like he is finally sobered up and aware of where he is. Gen bends down closer to him, locking their eyes intensely. Moment passed with Ryusui still tries to find his breath and to move his jaws around. It's as if he just starts relearning how to speak. Cute.
And when Ryusui finally finds his voice, he calls so weakly. "Ge... Gen...." he pants needly.
Gen listens. "Yes?" he encourages his lover to continue.
"Gen... I wan.... I wan it.... Ge... Gen..."
"Oh, you want it now?"
"Ye... yes ... I wan...."
The laugh from Gen is out of his control. Ryusui is truly adorable when he is asking the fruit of his labor.
"Okay, you worked so hard for it so I will give it to you," Gen soothes him. He bends down more to him, letting his still clothed chest brushes against Ryusui's naked one and cupping Ryusui's face tenderly.
And Gen gently plants a very long kiss into Ryusui's lips.
And Ryusui hums in satisfaction.
Truly, Nanami Ryusui always gets what he wants.
