Summary
     Gokudera and Yamamoto still miss Tsuna even when he's standing right
     in front of them.
Notes
     Request: Tsuna sandwiched between TYL!Gokudera and TYL!Yamamoto. Or
     maybe just Tsuna being molested by all his TYL!guardians. WE MISSED
     YOU, BOSS ;o;

"Hi, Tsuna!"

Training had lasted for hours, it had been ferociously demanding - when was Lal
Mirch ever anything else? - and things had been just as tough for the past five
days ... but when Tsuna was met with a smile as bright as the one Yamamoto was
giving, he had to return it. "Hi, Yamamoto," he said as the training room door
shut behind him, grinning tiredly and getting his hair ruffled for it. He
squinted around underneath the mess being made of his hair and wondered why
Yamamoto was waiting alone in the corridor.

"You look beat. I'm not surprised." Yamamoto jerked a thumb at Lal Mirch
marching away in the direction of the showers. "She didn't even say hi. All
business, huh?"

"Definitely," Tsuna said, massaging a wrist sore from the pressure of blasting
flames from his gloves. He tried not to react much when Yamamoto took hold of
his wrist and started massaging it for him, thumb moving in firm circles.
"Where's Gokudera-kun?"

"He needed to talk to Giannini about testing the base's security system. Hey,
it'll be a while before supper's ready. Do you want to go relax somewhere?"

They headed for a lounge a few doors down from the kitchen, sitting facing each
other on the couch. Yamamoto took hold of Tsuna's other wrist too and massaged
both, and something about his expression kept Tsuna from suggesting that they
do something else, less awkward.

"It won't be long now," Yamamoto said finally. "If Hibari's been switched, the
young versions of me and Gokudera can't be far behind."

Was that a relief or not? Tsuna thought instead of that morning, when Kusakabe
had showed them to the younger Hibari, and smiled. "I'm glad Gokudera-kun
didn't say anything to Hibari-san about being shot before the younger versions
of you guys. It looked like he was dying to." Gokudera had been terribly smug.
Tsuna couldn't remember this ten-years-later version grinning like that even
once before today.

"Ha, I'll probably have to keep him away from the older Hibari when we get sent
back to ten years ago, or they'll spend all their time fighting," Yamamoto
said. "And you won't be there to stop them." His hands stilled on Tsuna's
wrists, then gripped and pulled him closer - and closer still, and he put his
arms around Tsuna's shoulders.

"Sorry," Yamamoto said with a hard-edged laugh. "I'm sorry."

Tsuna reminded himself to breathe. "It's okay. I've got used to ... I know ...
well, Gokudera-kun already kissed me."

"He what?" Yamamoto barked, and right then Gokudera's voice echoed down the
metallic corridor. Well, he never was very far away, these days.

"Is the Tenth here?" The sound of footsteps and gusty sniffs came closer. The
sniffing changed to a purr and Uri walked into the room.

"Good job, Uri!" Gokudera came after, patting the leopard on the rump, and his
eyes fixed on Tsuna with the relief that was one of the hardest things to get
used to. Then Gokudera let his field of vision expand and saw how they were
sitting, Tsuna held to Yamamoto.

"Yamamoto! What the fuck!" he hissed, and the tone of his voice made Uri growl
in a you-look-like-lunch way.

"You kissed him," Yamamoto said, and Gokudera reeled back, horrified.

"I wasn't complaining!" Tsuna said, waving his hands. "And - and anyway, it was
actually on my ring. Gokudera-kun grabbed my ring..." At the last second,
bending abruptly to aim away from Tsuna's mouth. Tsuna had blushed so much the
next time he had to light the sky ring for training that Lal Mirch had thought
he'd done up a fever.

"But you think he was going to kiss you, right?" Yamamoto said mutinously.
"Gokudera, we agreed about this."

"Agreed to what?" Tsuna said, but at the same time Gokudera said, "Shut up," in
such a dead voice that Tsuna stopped trying to glare at both of them at once.

"Shut up, Yamamoto." Gokudera's head bent, but his shaggy ten-years-later
haircut wasn't long enough to hide the look on his face. Yamamoto didn't
breathe for a moment - Tsuna was close enough to feel how still he went, and
clenched his fists painfully tight and wondered what he could possibly say or
do.

"Tsuna. Can I kiss you too?" said Yamamoto.

"Buh!" said Tsuna, because he wouldn't have thought of that. But ... it would
show that he was okay with that kind of thing and then Gokudera wouldn't feel
guilty.

"Tsuna?" Yamamoto stroked his arms gently, but Tsuna recognised it as yet
another way of being desperate not to let go. And Gokudera's head came up, eyes
focusing sharply on them.

"I don't mind. I..." Tsuna caught the scent of Yamamoto's aftershave and
breathed in. "...I've been waiting..."

"Me too."

Yamamoto and Gokudera waited for him all the time; outside his training room,
outside the bathroom if he took a long bath, staying at the table when they
finished eating before him. They always waited, and accompanied him everywhere
- except when he went to bed. Each night they watched him walk down the
corridor to his bedroom until the door shut behind him. He'd started to suspect
that they still wanted to come with him, and then he'd wondered what he'd do if
it happened. Then he'd wanted them to.

He turned to face Yamamoto and braced himself with a hand on his shoulder, but
Yamamoto pushed him down so that his spine arched and they were chest to chest,
making Tsuna feel his own skin all over.

Yamamoto sure wasn't shy. His tongue swept into Tsuna's mouth as a hand
travelled up his back to hold his head in place. Tsuna swallowed noises and
Yamamoto's spit, and Gokudera said "Tenth," like it was ripped out of his
throat.

Dammit! Was he upset? Tsuna pulled away from Yamamoto with a wet pop that made
his ears burn as he turned around, and then his heart started thudding as he
saw Gokudera doing what he'd learned to do best: the details business. Uri was
already recalled to its box, and Gokudera walked to the door to shut and lock
it with two decisive clicks. Yamamoto made a noise of appreciation.

Gokudera looked over his shoulder. "Tenth?" he said, with way too much in that
word, like always, always.

"Say yes," Yamamoto said hopefully, stroking his arms again.

"Yeah," Tsuna muttered, one hand creeping over the couch because he thought it
might look stupid to hold it out to Gokudera, but he wanted to. Yamamoto
chuckled in satisfaction, and Gokudera came and sat on the couch, leaning
towards Tsuna without touching him. Yet.

"May I?" he said.

Tsuna almost shut his eyes at the tenderness on Gokudera's face. It seemed
private. He fixed his gaze on the neat knot of Gokudera's tie and buried one
hand in the spiky tufts of hair at the top of his neck. He grinned in elation
at the reaction this caused, Gokudera moving closer those few centimetres in
quick jerks and starts - and then nearly ate his face off.

Tsuna swore in shock but the kiss went on, an artful move of Gokudera's tongue
turning the spluttering into deeper kisses. The zip of Tsuna's hoodie squealed
as it got yanked down and hands rubbed his chest through his t-shirt - then
only one hand, the other making the zip of his jeans give that little metal
squeal and closing around his cock so fast it was like getting hard from
confusion.

"Gokudera!" Yamamoto said, laughing and groaning as Tsuna wrenched away and
fell back into him. "Too much!"

Tsuna panted, feeling his spine dig into Yamamoto's stomach and chest. Before
things could go wrong he grabbed Gokudera's shirt to show him he should stay
close.

"Yes," Gokudera said, "I'm sorry, thank you, yes, Tenth..." He wiped his mouth
with his sleeve and then cleaned Tsuna's face, and kissed him this time with
drawn-out gentleness.

"Gokudera-kun, it's okay," Tsuna said as soon as he had the breath. Gokudera
smiled like he'd already guessed that (a few things were better about the world
ten years later - Gokudera actually knew what he meant now, most of the time,
rather than hearing only what he wanted to) and nodded. He rubbed soothingly
over Tsuna's chest and shoulders, and Yamamoto nuzzled his neck.

If they were trying to calm him down, it wasn't working. Even the low-intensity
petting kept Tsuna acutely aware that his fly was open.

"What do you want?" Yamamoto said in his ear.

Tsuna lifted his hands hesitantly, then put them on Yamamoto's and drew them
between his legs. Yamamoto made a happy hum of appreciation, and Tsuna became
aware that Yamamoto was getting hard, big against his back. He shuddered.

"We can do more than that," Gokudera suggested, and a grin curled his mouth.
"We can do better."

"Yeah," Yamamoto said eagerly. "Gokudera, you—oh, yeah."

It was a total mystery why Yamamoto sounded so pleased. Tsuna was the one
getting his dick sucked. Gokudera's mouth was soft and hot and smoothly slick,
immediate and uncompromising. Tsuna also didn't know why he couldn't scream.

"Fuck into his mouth," Yamamoto said, and Tsuna's locked jaw went slack around
the sound of a long groan. His hands clutched at his hips to keep them under
control.

"Don't worry, Gokudera's done it before." Yamamoto grabbed Tsuna's wrists and
pulled them away. "Go ahead. He's good at it."

"I know," Tsuna snapped, because it was basically all he knew currently.

Yamamoto snickered. "Yeah. So go ahead. Do it."

His hips jerked forwards an unstoppable fraction of an inch, the thought too
much to resist. The shape of Gokudera's tongue remoulded around him and the
ridges on the roof of his mouth made him feel insane.

There was no protest at all from Gokudera, only an earnest quirk of
concentration in his brow and his head tilting to take more, the rhythm he made
in his mouth changing so that Tsuna couldn't help but do it again, and keep on
doing it. He moved as slow as he could manage, sore wrists jerking in
Yamamoto's loose grip.

"Sorry," Tsuna gasped. "Sorry, sorry."

"Oh, don't say that," Yamamoto said, his voice raw. "Don't you say that. Hey,
here—" He stuck two fingers in Tsuna's mouth like they were a treat.

Tsuna almost bit him in distraction, but managed to keep the clench of his
teeth gentle. He took up a rhythm of sucking and biting that matched the
movements of Gokudera's mouth, and the arm Yamamoto had put around his waist
clutched uncomfortably tight.

Tsuna slumped, dizzy and gasping, and Gokudera glanced up smugly. Then he gave
this wonderful muffled yell full of vibrations and - "What? No!" Tsuna whined,
because how could that mouth move away?

"What are you doing?" Gokudera snarled, yanking Yamamoto's fingers from Tsuna's
mouth.

"Getting ready," Yamamoto said. "Obviously."

"The Tenth is too young for that!"

"No way!" Tsuna said. Definitely not, not when he was so close. He still went
red at the shock on Gokudera's face and at Yamamoto hugging him.

"Tsuna wants to," Yamamoto said, sounding terribly pleased.

Gokudera was blushing too, and trying not to look pleased. "Tenth," he said
gently, stroking Tsuna's cheek. "It'll hurt."

He was saying that with his lips red and shiny from letting Tsuna's cock into
him, and he expected it to work? Tsuna dug his fingers into Yamamoto's muscled
legs and groaned in frustration. "Gokudera-kun!"

"Come on," Yamamoto said, gripping Tsuna's face and tilting up his chin. "Can
you say no to this face?"

Tsuna glared at what he could see of Yamamoto - just fingers - and then looked
at Gokudera after all, feeling put upon. "We can..." he tried. "You know ...
anything. Just. Please."

Gokudera kissed him, and then stood and said, "Not with spit." He looked at
Yamamoto. "We'll get the proper stuff if we're going that far. The Tenth has to
enjoy it. We're going to be careful."

"Can we go to bed?" Tsuna asked quickly, while he had the courage and before
Gokudera changed his mind.

"O~oh," said Yamamoto. "Oh yeah? So you want us there, in your bed..." He
pressed a kiss to Tsung's cheek. "Have you thought about that before? It'll be
a tight fit, haha—" and he squeezed with his legs. Tsuna wondered how he could
have got used to that hot hardness against his backside.

"We're not carrying you out of here, Yamamoto, get up," Gokudera said, taking
Tsuna's hand and pulling him off the couch. Tsuna grabbed at his open trousers
with a spike of embarrassment. He was astonished at how heavy it felt between
his legs and stumbled dizzily all the way to the bedroom; they said to go to
theirs, where the two single beds were pushed together. Tsuna was grateful in a
weird way to see it, because in spite of how everything in the world had gone
wrong, Gokudera and Yamamoto had each other.

They had him too. They had to know that, as he hitched his leg over Gokudera's
hip and opened to Yamamoto's thick, slick-hot cock and ground his own against
Gokudera's, thrust together into the tight circle made by Gokudera's hands as
his fingers tried to find that spot inside Gokudera that Yamamoto had found
inside him. When he came way too soon he told them to keep going, and Gokudera
kissed him so he wouldn't beg, and they went on until he was hurting hard and
then blessedly unwound all over again.

Gokudera whispered into his ear. "Thank you."

"You know he thinks it's weird when you say that," Yamamoto said, though Tsuna
was sure the words had been too soft for him to actually hear. (They'd probably
all got really good at guessing things about each other.) He reached over Tsuna
to rub Gokudera's shoulder in random, generalised comfort. Gokudera
automatically shrugged his hand off, and lowered his face against Tsuna's neck
for long moments before settling back on the bed, coaxing Tsuna to sprawl
against him.

"We missed you, Boss," Yamamoto said quietly, some explanation and some apology
in his voice.

"Don't have to," Tsuna pointed out, stretching, moving against both of them,
and smiled as Yamamoto's arm went around him.

The three of them drifted to sleep on a long sigh of relief.
