Work Text:
Gerard would totally be their accidental third wheel on some late hotel night, and then he'd just kind of end up sticking around to watch them fuck, noting the way Brian's hands would clench around Bob's shoulders and neck as Bob sucked his cock, lying between Brian's legs, and then he'd be all nnnrgh hard, and just lie back in the chair across from the bed and slowly jack off, biting his lip, and listening to the choked off cries that Brian made.
And after Brian came and was lying on the bed all sprawled and kind of wrung out, they'd have this whole conversation between them without saying anything, and then Bob would be crossing the room, kneeling in front of Gerard, and he wouldn't take him in his mouth like he had with Brian, but he'd sit there and very seriously and intently jerk Gerard off, teasing him, knowing exactly how to use his hands, and then bringing him off fast and hard right there in the chair with Brian watching interestedly from the bed.
By the time their next hotel night happened, Gerard would be all vibrating with interest, and Bob would take one look at him - like he hadn't since that night, because he's Bob, and he can actually handle all of his feelings, unlike Gerard who carries all of himself, his gut and want, on his sleeve - and nod sideways in invitation. He doesn't say anything, and Gerard just breaks into this grin, and shuffles his feet after Bob, not even bothering to say anything to the rest of the guys.
When they enter Bob and Brian's room, Brian's already half-naked, toweling off his hair, his expression like the sun splitting the sky open when he sees Bob, and then changing slightly when he sees that Gerard is hot on his heels.
It isn't as organic as it was last time, mostly because Bob is looking for an easier way to insinuate Gerard into their bed, while Gerard is like a freaking puppy, trying to figure where he can possibly squeeze in to the places between them. He feels like a kid, or something, wanting approval, which is ridiculous, because if there's one thing he's really freaking good at, it's fucking.
But the prospect of getting Brian and Bob naked, of being in between them, seeing their faces when they look at each other like that, with no guard or roadies or reality between them, turns him on harder and faster than anything just then. His heart's beating so hard when Brian reaches around and brings Gerard's back to Brian's chest and kisses a path from his shoulder to his ear, flicking his tongue out on every second kiss.
Gerard's eyes keep fluttering open and shut, and in between, he can see can see Bob moving slowly towards him, skin rippling with each move, and sliding his hands up Gerard's thighs, fingers rasping against the sparse hairs there. This time Bob doesn't hesitate, and he doesn't stop - he just takes Gerard's cock in his mouth and buries his nose in the pubic hair, wringing a ridiculously needy moan from Gerard's throat.
"He's good, isn't he?" says Brian conversationally against Gerard's ear, and a little proudly, like he was the one to teach him to do it, or something.
Maybe he was. That thought alone has Gerard rolling his head back against Brian's shoulder, gasping, his fingers twitching to touch the curve of Bob's jaw.
"You can," Brian says, his hand brushing Gerard's forearm, and that's all the encouragement Gerard needs, sliding his hand around to the back of Bob's neck, pulling him forward in a rhythm that makes his head spin. When he guides him back to the head of his cock, Bob makes this low stifled moan around him, and Gerard can feel it everywhere. Brian's pressed up against his back, hard and resting just right against his ass, and he rocks his hips forward, guiding Gerard back deep into Bob's mouth. He has to brace his hands on Bob's shoulders at that, letting him set his own rhythm, because just the thought of that, of being held tight between them, Brian fucking him from behind, Bob's mouth around his cock, is kind of the hottest thing that's ever happened to him.
He doesn't last long, not with Brian's teeth biting the back of his neck, Bob's tongue working the underside of his cock, and he comes with a wordless cry that could have started out as either of their names, but ended instead somewhere in between, neither and both, and maybe a few curses mixed in.
After, Gerard is feeling pretty wrung out, but buzzing with a kind of energy, still, and he slides out of Brian's lap back into the pillows, and watches Bob scoot forward and pin Brian to the bed, dragging him bodily until he's lying down. Brian settles back on the pillows and then they just - kiss. For a while. It isn't for Gerard's benefit, he knows that, but he can't look away, and he's idly playing with his totally not yet hard again cock, and just watches them kiss like two people who are not being observed by anyone, starting out slow and slowly, slowly building up in rhythm.
They're so fucking - tender and intense and Gerard watches as they just lick each other's tongues, bite each other's lips, and they're moaning, a bit, soft breathy sounds that feel like they're catching in Gerard's own throat. They're moving against each other, Bob's legs between Brian's, and Gerard is totally not watching their cocks rubbing against each other, red and leaking, except for how he is, and he thinks that maybe he could even get it up again, just from that alone. His hand speeds up a little on his own dick, just a bit, and he can feel it hardening, minutely, so he strokes harder, with more intent.
Then Brian reaches over to the bedside table and, wow, huh, Gerard hadn't even noticed the lube sitting there, but then it's in Bob's hands, and Bob flicks it open with a practiced gesture, slides some lube out onto his other hand, and drops the tube on the floor. Gerard can barely breathe when Bob slicks himself up, and fuck, fuck, Bob's cock is thick and longer than Gerard's, and it's mesmerizing to watch Bob's square hand running over it, all business-like and perfunctory. Gerard flicks his gaze over to Brian's face, and feels his cheeks flush. Brian looks fucking hungry for Bob, Gerard's never seen him look at that intense, that focused on anything and he's seen Brian be pretty fucking intense in all their years together.
That, and the sight of Brian's hands fisting the sheets in anticipation, jacks him up even further and now Gerard's fully hard and jerking off in earnest, desire pooling in his belly, and balls and he spread his legs a little, gives himself room.
Bob finishes slicking himself up, looks Brian in the eye, goes, "You good?" and Gerard is just anticipating maybe seeing Bob get Brian ready with his hands, with the same intensity and business-like attitude when Bob just kind of - shoves Brian's legs aside, adjusts Brian's hips right up against his cock and - just goes for it, slowly pushing his way inside.
Gerard knows his eyes just got a hundred times wider, and his hand speeds up on his dick. Watching Bob's cock disappear inside Brian, hearing Brian's broken gasp, like dry tears - he can't even take it. He needs to - he barely has the will to wait until Bob is all the way in and moving inside Brian before he sits up and, still pumping, grabs Bob's head with his free hand and meets Bob's open mouth with his own.
He thinks maybe he's going to startle him, like maybe they got so lost in each other they'd forgotten he was there, but Bob's kissing him back immediately, insistently, like he's been waiting, and he lets out a few quiet noises into Gerard's mouth as his hips move against Brian. He leans towards Gerard like he wants to grab him, kiss him more fully, but his hands are tight around Brian's hips, so Gerard wraps an arm around Bob instead, pulling himself closer so he's pressed up against Bob's side, their heads tilting together, his fingers brushing up against Bob's hip as he jerks himself off. When they break apart, gasping for breath, Gerard looks down at Brian and finds him staring up at them, lips parted, hands clenched into the bedsheets.
"He's close," Bob says against Gerard's ear, twisting his hips up hard, and Brian and Gerard each let out a sound at that. "I can feel it. You should..." he nods at Brian, then looks down at Gerard's hand, tight around his own cock.
Gerard knows what Bob's asking him for, he doesn't misunderstand, but Brian's lying there stretched out under them, hips jerking up against nothing, getting fucked back against the pillows with the force of Bob's movements, and he can't not. He slides away from Bob and stretches out on the bed beside them, leaning over and taking Brian into his mouth. "Jesus fuck, Gerard," Bob swears above him, and Brian is beyond forming words at all, one of his hands coming up from the bed to wrap into Gerard's hair, thrusting his hips up and coming down his throat in what feels like seconds.
Gerard rests his head against Brian's hip, letting out a protesting noise as Brian goes to take his hand back, so he leaves it there, tugging gently at Gerard's hair as he gets himself off, with his face pressed to Brian's skin and the movement of Bob's fucking shaking his whole body.
Bob leans over to bite Gerard's shoulder as he comes - hard, hard enough to make Gerard whimper against Brian's skin - and then he's pulling out, collapsing on the other side of Brian, then reaching down and dragging Gerard up to him, to kneel over both of them and kiss Bob until he can't breathe, can't stay upright, can only sag down against them both, feeling Brian's arm falling heavy over his waist, and kiss Bob like he's forgotten how to do anything else.
Eventually, Brian's shoving at his hip, squirming out from under him, mumbling, "You're gonna fucking break me," but he shifts Gerard around, settles him in between them, and curls up against his back, watching sleepily over his shoulder as Gerard and Bob kiss. Then Bob's the one crawling over, kissing Brian surprisingly lightly.
"Motherfucker can't ever keep his eyes open after he gets off," he says conspiratorially to Gerard as he settles back down against the pillows. Brian extends a middle finger in his direction, then leaves his arm draped over Gerard's chest, mumbling something incoherent against his back before his breath evens out into sleep.
"Should I..." Gerard starts to ask, moving to get up, but then Bob's hand's clamping hard to his waist.
"You do, and he'll wake up," Bob tells him, smiling a little softly over Gerard. Then he smirks. "Trust me, the fallout wouldn't be pretty."
Gerard grins into the pillow, relaxes under Bob's hand. "Guess I'll just have to stay, then."
Bob's thumb is rubbing circles against his hip as he nods and presses his face into his pillow, closing his eyes. "Guess so," he says decisively.
