You cum again for the fourth time in the last hour with a long, muffled cry. Satoru greedily takes in the sight of your legs trembling as you drip onto the sheets, the folds of your cunt pulsing the long vibrating silicone embedded deep into you. He can see the walls of your pussy tighten in an attempt to push out the intrusion, to relieve the overstimulation, but it fails.
Suguru doesn't even look at you, seemingly engrossed in the book in his lap, but Satoru can tell Suguru's patience is waning. His eyes trace the line of words down the page at a speed slow enough to tell Satoru that his interests lie outside of the book.
Mainly, in your spread body, forced open by a curse of Suguru's as the toy he placed in you an hour prior overwhelms you to the brink.
Satoru watches the black tendrils gyrate around the length of your thighs, completely exposing you to them. Suguru had placed you in a particularly humiliating position, ass raised to the air, face planted in the sheets, arms and hands bound by a black rope like entity Suguru had chanced upon during a mission a couple of years ago. Satoru can almost feel the tightness around his own wrists, the memory of it binding his own legs, and he grows even harder, cock straining against his pants.
It's perverted, it's perverse, watching the curse curl around your naked, glistening body, caressing you like a lover while you cry out for them. It's all Suguru in the end. The curses are a part of him, in a way that Satoru doesn’t blink at.
It’s different when someone else touches you, with an ease that signifies a lack of understanding for their position. You are not someone who can be casually touched anymore. Not by any man that isn’t them. 
You breathe out a sob. You've given up trying to upright yourself with your latest orgasm, and the tentacles dig into your flesh as you let yourself fall limp, your exhaustion evident. You've made a mess of the sheets, and all Satoru can think about is having you make an even bigger one.
Suguru closes his book.
Satoru grins. Without another word he shrugs off his shirt, and unbelts his pants.
When Suguru sits on the bed next to you, he easily pulls out the toy from you, glinting and wet with your juices, and you exhale shakily, relieved. The curse shrinks away at its master’s presence until it's only wrapped around your wrists, trapped behind your back. Suguru turns you around, and the two of them gaze at your weary body, your tear stained face, for a little longer.
“Have Satoru and I been neglecting you?” Suguru asks lightly, knuckles brushing the wetness from your cheek. His voice takes on a consolingly sweet murmur, “We’ve been busy lately, haven’t we.”
A repeat cycle of missions and meetings and days, seeing Suguru’s face in passing, and yours not at all. You’ve been holing yourself in your apartment for the last couple of days coaxing that hellcat of yours out of its place underneath the couch. As if sensing the approaching move, it had refused to come out, distressing you greatly. But Satoru is a new man, with patience and generosity to spare. He’ll endure that horrible ugly cat of yours (which looks nothing like him) that you refuse to be without, the monotony of missions and meetings, the constant squawking of the higher ups, if only to come home to you and Suguru at the end of the day.
And the rings of your fingers.
He’s a married man now, after all.
Everything changes when a man gets married, he thinks, looking at you. For better or worse, you’ve given yourself to them, unaware that they’ve also given themselves to you.
You blink, staring up at them with confusion marring your face. “N-no…?”
Suguru smiles. You balk, as if finally understanding where this conversation is heading. Satoru has to give you some points though, it’s taken quicker than it once would’ve for you to understand.
“That’s a shame,” Suguru breathes, “Satoru and I missed you,” he trails a finger down the valley of your breasts, and you shudder, squeezing your eyes tight as your nipples perk in response. Satoru can imagine your wrists straining against the confines of your binds.
“Aren’t you lucky,” Satoru crows, with a wide grin, enjoying the wide eyed panic settling on your face. “Having not one, but two husbands that miss you so diligently.”
“I missed you two too!” You blurt out, embarrassment alight on your face, more for the predicament you seem to be in than the words itself. Satoru could listen to you say you missed him over and over, if only you’d indulge him. It seems to him these are the only moments you’re most truthful to yourself. You never understand, not fully. You’ve always rationalized their love in ways it doesn’t make sense, especially when it’s never been rational in the first place. 
Satoru’s never been a picky man when it comes to you. He’ll take your increasingly distressed declarations of love over nothing. He knows they’re genuine at heart.
Maybe it’s all a last ditch attempt to placate them, to ask for forgiveness, but there’s only one way to placate the both of them, and it won’t be with words.
He moves closer to you, slotting himself between your legs as his hands spread you open once more. You make a small noise when you feel the hardness of him pressed to your slick sex.
“You’ll make Satoru jealous,” Suguru says, eyes glinting, as Satoru lines his cock up at your glistening entrance, “if you don’t give him as many orgasms as you gave that toy.”
“Double the amount,” he agrees with a heated look. Until you’re not thinking of anything but them. The way his cock splits you open and touches you in places only he can reach. He’ll make you feel so good you never entertain the attention of another man ever again. And then maybe he’ll grant you some reprieve. He can’t promise the same of Suguru though.
After Suguru, you might be a little too messed up to function properly for the next couple of days, but Satoru can think of nothing better than the two of them having you to themselves until reason inevitably grabs hold of you.
You try to squirm away, but to Satoru’s delight, black tendrils snake back around your thighs and hold you open. Suguru smiles innocently.
“I’m…” you hiccup, squeezing your eyes shut, “sorry…”
“I know,” Suguru says, settling into the bed, and freeing his cock from his pants. Satoru watches his hand firmly grip the base of his leaking cock, and wonders if Suguru’ll let him suck him off after he finishes his turn with you.
Suguru pushes the hair from your face, and kisses your sweaty forehead.
Your previous orgasms make it easier to slip into you, and Satoru sighs when the familiar wet heat of your pretty pussy sucks him in. Nothing in the world compares to the feeling of when he and Suguru fuck you together, in seperate holes, or one, but this comes pretty close.
“Ngh…” you moan, no doubt already sore and overextended as he pushes into you, past the lingering tightness. If Satoru didn’t know better, you’d be a virgin with how tightly your walls cling to him, but he knows he and Suguru have thoroughly divested you of that title long ago.
Satoru hums, stilling himself inside of you, letting you really feel him, despite the urge to wildly thrust. You lay almost limp before him, blinking away the wetness in your eyes. He smiles. “I guess I’ll just have to show you how much your husband missed you, yeah?”
Without another word of warning, he pulls out, and thrusts into you fully. You choke on your breath as he begins to fuck you in earnest, letting his cock drag against your folds before touching that part of you inside that he knows makes you lightheaded. His hands are wrapped around your waist, the black tendrils doing the work of keeping your hands bound, and your legs spread, forcing you down to him at the same timing of his thrusts.
You’re already on the cusp of another orgasm, sobbing, lips trembling in a way Satoru is tempted to bite. A few more thrusts and you’re shaking, squeezing around him as everything gets even wetter. It takes everything not to bury himself to the hilt, brush against your cervix, and come inside of you. 
His gaze drops to your cunt, to where the two of you are connected, and his blood runs hotter. Suguru is watching, pumping his wet length, chest starting to heave as he approaches what Satoru knows won’t be his final orgasm of the night. He’ll be inside you before long, painting your insides white, their seeds mixing into a mess inside you. 
The three of you, together, always together. It gives him a high akin to violence, to know you’re indisputably theirs in a way nobody can say anything about anymore, even you. You gave that right away when you said yes.
The room is obscenely loud as he fucks into you, wet squelches and the slap of skin against skin. Your legs have gone limp, held up only by Suguru’s curse, and your breathing goes funny in a way that makes him even harder.
“You’ve got some nerve,” he grunts, sinking himself into the hilt once more, “neglecting your husbands.” He hasn’t even played with your clit yet, hasn’t really made you sorry like he knows he could, but you’re already approaching your next orgasm, and even he isn’t strong enough to let you come by yourself. “Don’t worry,” Satoru says breathily, “We’ll take our time with you tonight. Make up for lost time. You’ll indulge your husbands, huh?”
You don’t get a chance to answer, or even register his question.
His hips slam into yours with reckless abandon, fingers marking indents into your hips. Satoru watches your face twist, watches as you try to fight off your impending orgasm, watches the shameless pleasure on Suguru’s face when you start to become incoherent underneath him. He feels the vice tight squeeze of your cunt, and presses your raised thighs until they’re nearly level with your chest. With one final thrust, he comes inside of you, feels your pussy pulse with his release. Your feet on either side of his head twitch with the aftershocks of your orgasm.
You’re a pretty sight, nearly bent in half, half sobs escaping your mouth, his hands on both sides of your head, as he keeps your hips flush together. Every small movement sends the legs resting on his shoulder into overdrive. He meets Suguru’s gaze, trails his eyes down the flexing muscles of Suguru’s abdomen, to the painfully erect need between his open thighs.
Satoru snorts. Sometimes he can’t decide on whether or not Suguru is a masochist or a sadist. If he’s indulgent to the point of excess, then Suguru is restrained to the point of delayed gratification. 
You shiver when Satoru slips out of you, your leaking cunt a sticky mess. You look blankly serene, gazing up at the ceiling. Not a single thought in that head of yours, just the way he likes it. He and Suguru have always been of the opinion that you think too much. If he can give you quiet, then he’ll consider it one of his husbandly duties.
He almost feels bad for you when Suguru claims his seat, after giving him a long kiss. Satoru can’t help but reach and give Suguru’s cock a hard squeeze, relishing the harsh grunt that leaves his throat, and the warning nip of Suguru’s teeth against his neck.
You blink, as if regaining some semblance of cognizance, when Suguru’s hardness taps against your stomach, smearing it wet with precum.
You blink when Suguru brushes your face with his knuckles, takes your hand, adorned with the ring they had given you, entwines your fingers, and smiles.
-
Satoru watches as Suguru fucks you in a new position. It looks like punishment, and it must feel like punishment too. The rough, measured thrust of his hips slaps against your nearly limp form, a foamy white ring around his cock as he unrelenting spears into you. The weight of him against your back pushes your body deeper into the bed. Rivulets of come slide down the curve of your ass, dripping onto the sheets. 
You’ve long given up on trying to fight. Suguru had unbound your hands in what seemed as if it might be temporary forgiveness. But then you had tried to run away. Suguru can be capricious too, because after sighing earlier that he could be tempted into forgiveness with a few more direct ‘I love you’s’, he had decided then and there that you needed to be thoroughly chastened. Your wrists hadn’t left your back since. 
Suguru’s fingers are wrapped around your throat, with just enough effort to keep your head upright as he murmurs into your ear. 
When Satoru sticks two fingers in your mouth, and presses against your tongue, your jaw easily falls slack, drool pooling down his wrist. Your eyes are glazed over, any indication of consciousness in the slight shift of your breathing.
This might be the most fucked out Satoru has ever seen you. And he’s seen you in multiple, varying states of dissociation following sex. He feels his dick twitch in interest, a rush of blood following. A challenge it’d be, to bring you back to a world of awareness. To have you calling his name after you had been nearly unresponsive just minutes prior.
Suguru comes with an exhale, and you with a whimper as tears rush to the surface of your eyes, animating you back to life once more. Suguru spends the next few minutes rutting his hips into you, fucking their cum back into you with a vigor that tells Satoru that he’s thinking about children. 
The two of them have come inside of you so many times that Satoru thinks there isn’t a possibility of you not being pregnant. They’ve made a game of it, whose seed will be the first to take. You leak when Suguru leaves you. The curse enveloping your wrists dissolves into air. Suguru takes your wrists with his hands, and gently rubs his finger over them.
The two of them look with unabashed interest when Satoru pushes down on the slight distension of your lower stomach, and you leak even more, a mixture of your slick and their come onto the sheets. You blearily watch, unable to do much more.
Satoru’s eye catches on the glint of the pretty rock on your finger as he pets your hair. You’re theirs now. Formally and forever. 
Well, he thinks. They have all the time in the world.
