too good twenty-nine

Summary:

He finds himself between them, Grian's leg draped over his thigh, Kirsty's tits pressed against his arm, feeling them both breathe against him. It's peaceful, until Grian speaks.

“Your girl's a firecracker,” he says, “You'll have to let me borrow her sometime. I wouldn't get that kind of treatment at home.”
Jimmy just huffs out a little laugh, but Kirsty hums thoughtfully, squeezing Jimmy's bicep.

“Your birthday is coming up in August, G,” she says, and then suddenly Jimmy is imaging it.

--

Jimmy gets birthday sex, but Grian and Kirsty get something out of it too.

Notes:

Wrote this in a fever today? It's not fully polished but I think this is as good as it gets. Thank you Cara | Ex0rin, and Jo | blacktofade (my beloved) for the encouragement on this.

Happy Birthday, Jim. May you never read this.

Work Text:

It’s all Jimmy could have ever wanted. He's straddling Grian's hips, already full of cock when Grian pulls him down against his chest, and Kirsty presses the tip of her strap against Jimmy's hole from behind. He's already stretched so tight around Grian but he knows he can take them both. It's all he wants, and he can't help but moan, face buried in Grian's chest when Kirsty slips in; he’s nice and stretched and slick, and it's even easier than he'd imagined. 

And it feels so good. The first time Kirsty moves, Jimmy groans and folds, and feels the vibration of Grian’s moan through his chest and the way his hands grip Jimmy’s thighs hard. He's being so restrained, when Jimmy knows from experience just how much he likes to be in control. But they're letting Kirsty set the pace, letting her decide how fast or slow she fucks into Jimmy, her strap sliding against Grian's cock inside. Each stroke has Jimmy shaking against Grian's chest, his own cock trapped between their bellies and leaking against Grian's navel. 

It's too good. Just the right amount of friction, paired with the sensation of being stretched with every thrust. He's coming fast and hard, locking up, pulling a deep and desperate groan from Grian, who seems to be using every ounce of his will to stay still and let Jimmy enjoy it. And when the sensation gets too much, Kirsty slowly pulls out, her palm against his lower back, and helps Grian roll him over onto his back to catch his breath. Neither of them have gotten off yet, but Jimmy's not too worried about it. It's his birthday after all, and they have plenty of time.

.

He finds himself between them, Grian's leg draped over his thigh, Kirsty's tits pressed against his arm, feeling them both breathe against him. It's peaceful, until Grian speaks.

“Your girl's a firecracker,” he says, “You'll have to let me borrow her sometime. I wouldn't get that kind of treatment at home.”

Jimmy just huffs out a little laugh, but Kirsty hums thoughtfully, squeezing Jimmy's bicep.

“Your birthday is coming up in August, G,” she says, and then suddenly Jimmy is imaging it. Kirsty holding Grian down, making him take her cock. What noises would he make? How hard would he come? He's suddenly very aware that neither of his partners have gotten off yet, and that he's also not in any state to help with that at the moment.

“Um,” Jimmy clears his throat. “I wouldn't object to a little show. Y'know, as a birthday treat. If you wanted.”

He sees Grian's eyes flick over his shoulder to Kirsty, a small smile twitching at the corners of his lips. And then, as Jimmy looks over his shoulder to gauge Kirsty's thoughts on the matter, she's already climbing over him into Grian's lap, strap slapping loudly against his stomach.

They're kissing, deep and hard, which is the last thing Jimmy had expected. There's always been a tension between them, but he just assumed that was about him, not that they were actually attracted to each other. Not that they wanted to fuck .

He feels his stomach drop when he sees Grian reach down to roll off the condom from their last activity (he hates wearing them, and he’s annoyingly vocal about it, but it really does make anal a bit easier), pulling Kirsty against him, and she giggles with delight. 

“Hold on,” Jimmy finds himself saying, reaching out, hand on Grian's chest between them. “Just. Just the pegging.”

Kirsty looks at him, clearly a little disappointed, and maybe it's a little hypocritical of Jimmy. If he gets to sit on Grian's cock, Kirsty should be allowed to too, but somewhere inside there's a small and vicious part of him that wants to keep that part of her for himself. One thing that Grian can't have, that Jimmy doesn't have to share.

She seems to understand though, sits back against Grian's thighs, swinging her hips a little to draw attention to her needlessly glittery-pink cock still firmly in it’s harness.

“How do you want it?” She asks, and Jimmy watches Grian gulp, and there's instantly something different about his demeanor. He scrambles underneath her, turning onto his belly, pushing his hips up to her. 

Jimmy briefly wonders if he would be called upon for prep; Grian had done the honors for him earlier, Kirsty's nails being far to long and pretty to be useful. But Grian just reaches back and curls a first around Kirsty's cock, guiding her forward with little ceremony.

“Just a little more lube. You don't have to be gentle.”

Kirsty looks to Jimmy, surprised but wordlessly taking the bottle of lube from him, stroking a thin, slick layer over the length of her strap, and Grian pushes his hips up higher at the sound of the cap clicking shut. He's quiet in a way that Jimmy hasn't seen before, and he would question if this was even something Grian really wanted, if it wasn't for the silhouette of his thick, hard cock hanging between his thighs. 

Kirsty pushes in and Grian moans into the sheets, turning his face away. It's all the encouragement Kirsty needs, and she starts fucking him, starting slow and even but working up to harder, deeper thrusts that have Grian making noises Jimmy can't even put words to. It's not long before Grian has a hand on himself, stroking fast and hard in time with Kirsty's thrusts, and the sound of it is so filthy that Jimmy feels his cock stirring again, despite his exhaustion from round one.

Not to mention Kirsty has a mouth on her, asking Grian if he likes it, if he’d been jealous seeing her fuck Jimmy and knew he needed her nice big cock inside him. It’s something Jimmy loves about her, the fact that she gets off on fucking him as much as he does (and maybe that’s part of the reason why Grian is here, getting railed in Jimmy’s bed, instead of at home with his wife). She’s relentless, and Grian is practically whimpering when he comes, reaching back to pull her deep and hold her there while he shakes. It's safe to say Jimmy has never, in all their years of fucking, seen him fall apart like that before.

He's fully hard again when Grian's done, and Kirsty can barely wait to climb into his lap and ride him until they both come.

.

Grian's staying for the weekend, so they wake up together on Sunday morning, all three of them squashed into the bed, sticky and sweaty. Grian is quiet (for once) when he gets out of bed for a shower, and Kirsty snuggles up to Jimmy's side, drawing her finger across his chest.

“What would you like to do today, my love?” She asks, and Jimmy as some ideas , but they probably shouldn't spend the whole weekend getting sweaty. He’s got to be brave.

Kirsty cooks them all breakfast, and they drive out to the woods for a walk. Grian and Jimmy tussle in the grass and Jimmy limps back to the car with a semi and a bruised ego. (Well, maybe not quite bruised. He really was asking to be pinned down like that.)

Grian's flushed with sunburn across his cheeks and nose when they get back, and he rolls his eyes when Kirsty insists on dabbing him with after-sun. Jimmy watches as Grian sits on one of their barstools for her, staring unashamedly into her cleavage as she attends to him. And then he has the fucking nerve to smirk when he catches Jimmy watching him. The urge to wedge himself between them has Jimmy's hands shaking, a hot pit in the bottom of his stomach, and – he's just not sure if it's desire or jealousy.

“I know what I wanna do,” he says, and they both look over with sparkling blue eyes.

.

She always feels perfect around his cock. Soft and wet for him. But he's never fucked her while Grian fingered him before. 

It's almost as overwhelming as the double penetration - Grian's got two fingers deep in him, using them to guide Jimmy's hips as he fucks his girlfriend, stretching him as he pulls out, sliding deep as he presses in again. And every time, Kirsty clenches around him, tight and hot, telling him how good it feels, how good he feels. 

He's embarrassingly close already by the time Grian is behind him, rolling a condom over his cock (complaining under his breath) and lining himself up to push inside. Jimmy tries to brace himself on the bed, but he always forgets just how big Grian feels at first, and Jimmy buckles as he sinks in, letting the momentum push him deep into Kirsty.

She gasps in his ear, thighs hugging his hips, and Jimmy manages to gasp out a breathless “Sorry, love,” as he pulls back, only to be pushed back in with Grian's second thrust, wrenching moans from both Jimmy and Kirsty beneath him. 

“Don't stop,” Kirsty urges him, her hands on his hips for encouragement, and Jimmy groans as once again he pulls back, following Grian's lead, letting him set the pace this time. Another deep, steady thrust has him moaning aloud, head hanging against Kirsty's shoulder. Grian stills, sunk inside him, holding him right there, and his voice is low and surprisingly gravely when he says “See, that's what she needs. Nice and deep.”

Jimmy feels heat flare up in his cheeks, and burning in the pit of his belly. Grian slowly grinds into him again, pushing him down into Kirsty. 

“Right there, sweetheart?” Grian asks as she moans, her head falling back, and Jimmy can feel the way she clenches around him, trying to keep him there. “Should probably touch her Tim, you're not gonna make her come like that.”

Another deep thrust at unfortunately the perfect angle, Jimmy's already riding that edge when Grian's cock strokes his sweet spot from the inside. He stays there inside Kirsty, buried to the hilt as she squeezes him, and takes each of Grian's firm thrusts as they pick up speed, fucking him into the sweet heat below him. He can feel and hear how wet Kirsty is, the sound of it filthy and wonderful in his ears. It's so much, it's- overwhelming.

“I'm gonna,” Jimmy says, weakly, trapped between the two of them, and Kirsty whines softly, lifting her hips like she's trying to meet every one of Grian's thrusts. Jimmy imagines himself pressed inside her, cockhead nudging against her cervix on the very deepest thrust. The thought of her sore and still begging for it has him trembling.

“You're not coming already are you?” Grian snaps, but it's too late. Jimmy is coming, forehead against Kirsty’s collarbone as she cradles his head. It’s too good, and he shudders as Grian fucks him through it, barely slowing down at all even when he’s spent.

“C’mon Tim,” Grian grunts, taking a moment to push in slow, really grind into Jimmy, into Kirsty beneath him. “Look at her. She wants to come on your cock, are you gonna disappoint her?”

“No,” Jimmy grits out, finally lifting his head, and Kirsty cups his cheeks gently, pulling him in for a kiss as he musters up the energy to rut into her, even as his cock starts to go soft, even as it hurts so good. Even as he feels too much. 

“You like that, Kirs?” Grian asks, and Jimmy feels her get tight around him again, a breathy moan punched right out of her chest. “Timmy thinks you’re that wet and worked up just for him. I know better.”

Oh , Jimmy feels his belly pull tight and his cock throb inside of her. He won’t come again, can’t, surely? But Grian is still inside him, still pressing into him just right, hitting that good, good spot.

“He doesn’t want me to fuck you. But I know you’d let me.”

“Don’t stop,” Kirsty says again, more breathless than before, and drops a hand from Jimmy’s face to wedge it down between them, trying to touch herself despite the lack of room, with Grian’s weight against them  “Oh, fuck. Please.”

“See Tim?” Grian asks, voice rougher now, “Just have to give her what she needs.”

“Oh, fuck ,” Kirsty wails, her head falling back, and with her coming and clenching around his half-soft cock, and Grian still steadily rutting into him, Jimmy feels that tightness in his belly again, a wave of pleasure threatening to break, swelling, breaking, sweeping through him. He doesn’t even know if he’s coming again, it’s just happening, and he finds himself arching into it. Gladly taking every one of Grian’s thrusts, almost disappointed when Kirsty reaches out to stop him, having reached her limit.

It takes a minute to find his bearings. There’s the unpleasant but grounding sensation of Grian pulling out. Kirsty is panting beneath him, her chest heaving, and he rolls away as she presses her palm to his shoulder to get some air. It’s the movement of Grian rolling off the condom again that catches his eye despite the post-orgasm fog in his head, and he finds Grian watching Kirsty with a look that Jimmy can only describe as predatorial. He holds her gaze as he sinks one knee down onto the edge of the bed for support, fist loose around his cock. It doesn’t take him long, just a few firm and sure strokes of his fist, eyes flickering away from Kirsty to Jimmy, down to Jimmy’s soft, wet cock lying against his thigh.

“Didn’t think you’d come that fast, Tim,” he says, like the words are hard to get out. “Pathetic.”

And then he comes into his own fist with a soft grunt, eyes falling shut, brow furrowed and jaw slack. Jimmy watches his stomach flex with the force of it, and – fueled purely by lust – summons the last of his energy to scoot forward; the urge to lick Grian’s hand and cock clean too strong for him to ignore.

Grian exhales sharply at the first touch of Jimmy’s tongue, then sighs deeply as he sinks into his mouth. He tastes salty and sharp, and a little of latex, but Jimmy sucks him clean, until he feels Grian’s cock start to soften against his tongue. He can’t help but make a satisfied little noise, a hum of pleasure that makes Grian grunt. When Jimmy looks up at him, Grian meets him with a fond gaze, palm against his cheek.

“You two,” Kirsty sighs, from where she’s tucked herself in at the head of the bed. There’s something soft in her eyes too, even as she rolls them. “Ridiculous.”
