"Move," Tony murmurs, pushing Bucky under the shower head. Tony slips to his knees and Bucky's fingers slide into Tony's hair so naturally. Bucky leans back against the wall a little and sighs in anticipation. He enjoys the warm water that pours over his body and he enjoys Tony's warm lips even more than that. He groans softly as Tony presses slow, teasing kisses to his belly. His tongue darts out between thin lips as he worships Bucky's skin, licking lightly and dipping his into his navel. Tony smirks when that earns him a soft moan and Bucky's fingers tighten in his hair.

Tony shushes him because he and Bucky aren't supposed to be showering right now and they know Steve is in the adjacent room. In one smooth motion he pulls Bucky's cock into his mouth and runs his tongue around the head. Bucky looks down at him through the water and pulls Tony's head closer, pushing himself deeper into Tony's mouth, not that Tony minds. He takes what he's given, closing his eyes and sucking harder.

Bucky's panting and leaning against the wall. His eyes slip closed as he hones in on his body's reaction to what Tony's doing. He feels Tony's mouth, so wet and warm and thorough. Bucky hears the sounds of water trickling down the drain and the sounds that are coming out of his mouth and everything else is just a distant buzz.

Bucky tries to think of something to say but he can't. He doesn't want to interrupt Tony's process as he feels Tony's hand slip up from his ankle to his calf, caressing it slowly. Tony pulls away only long enough to press worshipping kisses to Bucky's thighs, groaning softly because he loves this. He loves it so much, loves to feel Bucky's muscles tense beneath his touch, the way his skin raises with goose bumps, loves the way he tastes. And Bucky tries so hard not to thrust into Tony's throat and Tony wishes he could be better at this for Bucky. Steve's good at it, but that's not who Bucky wants right now.

Bucky's close when he pushes Tony away. He'd rather have Tony's mouth on his lips than on his cock so he kneels and wraps an arm around Tony's shoulders, his other hand going to his hard cock. Bucky strokes quickly and their kiss is fierce and mostly teeth and tongue, and Tony loves the way Bucky moans when he comes because he can feel the vibration in his mouth.

Bucky drops his hand from his cock and leans against Tony, warm, content and exhausted. They stay like that for a while and only when Tony comments that Steve will probably come looking for them soon.

"Tony, we need to talk," Steve announces when he walks into the bedroom. Bucky is messing around in the kitchen so Steve figures this is a good time. He lets out a shaky breath and clears his throat.

"What about?"

Steve hesitates and takes a seat on the bed next to Tony's legs. Tony is still in bed, slightly hangover from his and Bucky's escapades the night before, so he doesn't protest when Steve puts a hand on his thigh.

"I think we should go back to the way things were six months ago."

Tony's eyebrows furrow as he tries to remember what changed six months ago. Steve sighs heavily but in Tony's defense he's still sort of hung over and he's not concentrating.

"Before Bucky moved in."

Tony sits up because no. He doesn't want that at all. It's been the three of us for a while now. I thought we were okay." He puts a hand to his forehead for dramatics and shakes his head.

"Obviously things aren't okay, Tony. It's different now. We hardly spend any time together anymore."

"We can spend more time together."

"Okay, it's just-sometimes I want to be alone with you."

Tony frowns and tries to make it sound casual. "I thought Bucky was your friend."

"He is. Which is why I think he'll understand if we ask him to step out of the picture for a while."

"Okay, no. I don't want that. Why are you kicking him out?"

"I just feel like we're drifting apart."

Tony snorts, "That's because you're the one who refuses to spend time with us."

"Because you two are always fooling around with video games and you know I don't like that type of thing. Look, I'm just asking for a little while. Maybe a few months until we see how things go. I'm expecting you to tell him because you're the one who started this."

"Started this? You're the one who wanted a fucking threesome for your birthday," Tony scowls. "He was your friend first. If you hadn't mentioned it nothing would have started."

"Why are you getting upset? I just want things to go back to normal."

"Maybe I don't."

Steve blinks furiously, cocking his head to the side. "What's that supposed to mean?"

Tony pushes out of bed and has to grab onto the bedside table to stop from falling over because he's sort of dizzy.

"Tony," Steve persists but Tony stumbles into the kitchen where he sees Bucky in all of his shirtless glory standing in front of the toaster.

"What is wrong with you?" Steve sputters.

Tony spins on his heel and extends a hand in Steve's general direction. He's got a headache and fighting is the absolute last thing he wants to do right now. "Stop. Okay? Just stop, because I'm not in the mood for this shit."

Bucky slowly turns around with curious eyes, as if he's a kid in the middle of bickering parents, and takes a bite of his toast.

"And you know what? You can tell him since you're already in here. I'm fucking done," Tony mutters as he's walking back to their bedroom.

Steve sighs and doesn't even look at Bucky before leaving their place altogether.

Bucky is so confused and he doesn't know what to think, so he decides to leave his toast on the counter and follow Tony. When he catches up with him Tony is standing in their bathroom with his toothbrush in hand, just sort of staring into space. Bucky approaches Tony wordlessly, wrapping him in a hug and Tony can't help but glance over his shoulder. Bucky presses his lips to Tony's cheek he doesn't move or speak because he doesn't really want to. He just wants to soak in this moment because he doesn't know how many more of these moments they'll have together.

"Hey," Tony finally says.

"Is everything okay?" Bucky murmurs.

Tony groans because doesn't want to do this but he doesn't want to dwell on it, either. He just needs to get it over with. "Uh, yeah, not really. Actually, Steve thinks it'd be better if you stepped out of the picture for a little while."

"That's what you guys were arguing about?"

"Yeah."

Bucky swallows and blinks slowly. He's not really sure what to think or say but when he looks at Tony's reflection in the mirror he knows Tony doesn't want this. He can sense it even through the haze of Tony's sort-of-hangover.

"Did he say why?" Bucky asks quietly, and Tony lies when he shakes his head 'no.' "So why couldn't Steve tell me himself?"

"He says I'm the one who 'started this', whatever the fuck that's supposed to mean." Tony pulls out of Bucky's embrace and crosses the bathroom to the shower and Bucky starts to leave.

"This wasn't my idea," Tony says quietly. "Just for the record, I want you here."

Bucky smiles sadly at Tony because he can tell. He knows.

"I'll go get my stuff," Bucky nods.

Bucky is gone by the end of the week and Tony doesn't know how to cope. He doesn't play video games or watch TV and he doesn't eat hardly anything. He spends his time in the lab listening to music and trying to avoid Steve because things are tense and he really doesn't want to have to deal with his husband right now.

Tony is zoned out until his music stops and he turns around to see Steve standing ten feet away. He looks unsure, like maybe he shouldn't have interrupted Tony or turned off the music, and the expression Tony greets him with only confirms it. But Steve is wearing only a pair of tight briefs and a black tank top and he looks so hopeful. Like maybe he can convince Tony that Bucky being gone is for the best. Like maybe if he can get Tony to fuck him things will be okay. Like maybe he reminds Tony that they're actually married they can actually fix this.

And Tony can't. He just can't look at Steve. He doesn't want to and he thought better of Steve than to try something so low.

"Did you need something?" Tony mumbles as he turns back to his tumbler of scotch.

Steve stumbles over what to say and he feels sort of foolish for even trying such a thing. "Uh... no, not really. I ordered a pizza for lunch if you're hungry."

"You don't even like pizza."

"But you do."

"Why would you assume I wanted pizza?"

"I just thought you might be hungry, Tony. A simple 'thank you' would suffice."

Tony grunts and downs the rest of his scotch with a grunt of acknowledgement just so Steve will leave the room. He does, and Tony pours himself another glass.
