Bruce sighs in pleasure as Tony kisses his neck and runs his fingers through his chest hair. They're set back-to-chest, Tony behind Bruce and holding him tightly with his legs. He shivers when Tony stops touching him with one hand to tap his phone and the vibrator in Bruce's ass switches settings.
"Better or worse?" Tony murmurs into Bruce's ear.
Bruce groans, the deep, low pulse of the new setting feeling like it's echoing down to his toes and all the way into his brain. "Oh, god, so much better."
Tony chuckles and trails one finger over Bruce's hard cock. "We have a winner," he says, then turns Bruce's head sideways so they can kiss.
Bruce sighs into the feel of it, the way Tony's hand holds his jaw so carefully, but his tongue is insistent and possessive. He rolls his hips to make the vibrator shift, and Tony swallows his gasp when the movement makes him see sparks behind his eyes.
"Well, welcome home to me," Pepper says from the bedroom doorway.
Tony doesn't let Bruce go right away, holding him still for another long, hot slide of their tongues before dragging his fingertips over Bruce's stubble as he breaks the kiss. "Hey, Pep," he says, still looking at Bruce. "We've been waiting."
"This doesn't look like waiting," Pepper says, amused. She kicks off her shoes and pulls off her blazer.
Bruce presses back against Tony, making him hiss when he puts pressure on his dick. "Doesn't feel like waiting, either."
"It feels exactly like waiting," Tony retorts, nipping at Bruce's ear. "No ganging up on me."
"It can't be ganging up if there's only two of us," Pepper says, her skirt dropping to the ground. She's wearing a silk camisole and matching panties, tiny bows on the sides that Bruce immediately flips back and forth with his thumbs when she kneels over his lap. She tilts his head up with one finger and kisses him softly, then presses her thumb to his bottom lip as she leans over his shoulder to kiss Tony the same way.
Bruce nuzzles her breast through her camisole and bites lightly at her nipple. She arches against him, and Bruce slides his hands over her ass, pushing his fingers through the leg holes of her panties as she rocks against him, the silk of her panties dragging on his dick.
"Oh," Pepper breathes out, and Bruce looks up from nibbling her shoulder to see she's got Tony's phone in hand. "And which of you is wearing this very dangerous toy?"
"Not me," Tony says, sounding delighted. He cups the back of Bruce's head, tugging lightly at his curls. "We've been testing the settings. Number six seems to be a big hit."
Pepper gives Bruce a teasing look. "May I?" she asks, waving the phone.
"Please," Bruce replies, dragging an open-mouthed kiss along her collarbone. He groans loudly when the vibration changes to short, fast bursts. "Oh, shit."
Tony chuckles in his ear, and he lightly cups Bruce's balls. "Is that nice?"
Bruce presses back against Tony again, dropping his head onto Tony's shoulder when Tony grabs his waist tightly and rubs his dick into the top of Bruce's cleft. Bruce hisses at the way the head of Tony's cock catches, and he hisses again when Tony bites at the tendon in his neck.
"My pretty boys," Pepper murmurs. She pulls off her camisole and grinds against Bruce's dick when Tony turns his head and sucks hard on her nipple. "Oh, that's so good."
Bruce drags down Pepper's panties and drags his knuckles against her slit. She rocks back and forth, using his first knuckle to work her clit, and she shivers as she taps Tony's phone again.
"Ah!" Bruce yells, his whole body jerking at the slow, rolling pulse that runs through him. "Oh, god."
Pepper tosses Tony's phone to the side and reaches for Bruce's dick. She slides the head into her cunt and holds still for a moment, clenching around Bruce and grinning when buries his face against her breast. "I would like to come home to this every, single day," she says.
"I'm all for it," Tony replies. He noses into the sweaty hair at Bruce's nape and reaches down, slowly pulling the vibrator from him and slipping two fingers into place.
"FUCK," Bruce shouts.
"Oh, there he is," Tony says, biting at Bruce's neck again. "Yeah, let us hear that filth."
Pepper kisses Bruce before he can say anything else. She holds his head in her hands as she slowly sinks into his lap, hot and wet around his cock. Bruce moans into her mouth. It turns into a howl when Tony takes out his finger and presses the head of his cock into Bruce's entrance.
Pepper finishes the kiss with a wet drag of her mouth along Bruce's jaw. She bites him behind the ear and turns her head to kiss Tony. "He's so big," she says against his mouth.
"Yeah?" Tony asks, breathless already. He rocks forward, sinking into Bruce another inch and causing Bruce to push up into Pepper.
Pepper groans and throws back her head. Bruce lunges forward, needing to taste the sweat on her neck. "Oh, fuck," Pepper gasps, squeezing around Bruce's cock and pushing down firmly, sending Bruce back towards Tony.
Tony buries his face in Bruce's hair. "Fuck. You're so tight, Bruce. It's amazing. You're amazing. I could fuck you all night."
Bruce yanks Tony's arms around his and Pepper's waists, adding his own arms around Pepper before thrusting up hard. Pepper squeaks and digs her fingers into his shoulders, then grinds down slow and hard.
"Oh, god," Bruce says, trapped by Pepper's weight and movement as Tony pushes the rest of the way in.
"Shit," Tony whispers. "Fuck. So tight and so eager for it, aren't you?"
"Yes," Bruce says because his filter is long gone. There's no point to pretend he isn't frantically in love with them or how they're fucking right now. He tilts his head so Tony can bite his neck again, slips one hand down so he can play with Pepper's clit.
"There, there," she pants, lifting off her slow grind to fuck him faster. "Oh, god, keep doing that, Bruce. Keep doing that."
"Got you. I've got you," he says, then keens when Tony bites extra-hard and starts to fuck him deep.
"Fucking love you like this," Tony says. "Incoherent. Sweaty. So fucking sexy."
Pepper kisses Bruce again, her thumb catching on the corner of his mouth. She tweaks his nipple with her other hand, rubbing frantically against his hand on her clit as Tony insinuates himself into their kiss, his hot, panting breath making Bruce feel every single spark of his impending orgasm.
"I'm--" Bruce shouts and fucks up into Pepper, then presses back down on Tony. Back and forth, back and forth. His mind utterly clears. All he can feel and see and smell and taste are Tony and Pepper.
His orgasm takes him with a hard, whipping feeling low in his belly. He digs his fingers into Pepper's waist and drags his mouth across Tony's goatee, searching for a kiss.
"Got you. We've got you," Tony says against his slack jaw. "Let us take care of you, sweetheart."
Bruce nods drunkenly and lets them use him as they need. He loves it, the way they gentle themselves now that he's come but still needing him between them. Pepper moves more languidly, and Tony's thrusts slow. Bruce rolls through the aftermath of his orgasm, the residual flare of need and endorphins keeping him loose and cuddly. Pepper comes next, reaching behind Bruce to tug at Tony's hair. He grunts, and his thrusts stutter for a few strokes. He comes a handful of seconds later, mouth open on Bruce's shoulder.
It takes a few minutes for them all to move and settle in the bed. Pepper has to lift off first, and once she's flopped onto her back, Tony guides Bruce down so he's lying on his side, Tony spooned behind him.
Pepper reaches out and strokes the inside of Bruce's arm. "Okay?" she asks.
Bruce is too tired to even try and laugh. He gives her a smile. "Great. You?"
"Fantastic."
"And I am just fine," Tony says as he sits up and reaches for the comforter, dragging it over the three of them. "I declare it nap time."
Bruce lifts his arm, and Pepper turns so she can press her back to his, making them a trio of spoons. Tony snuffles into the back of Bruce's neck for a moment before he fully settles. Bruce forces himself to stay awake for another half a minute, to be sure they're comfortable and content before he lets himself drift off into a nap.
