Summary
     Tsuna and Gokudera try to be even more awkward with each other. The
     attempt is a great success.
Notes
     Written for this_request: GokuTsuna - "Stumble", PG-13 - NC-17 (would
     kill for the latter)

"Hey, guys! Wait up!"
Tsuna froze, and felt Gokudera doing the same beside him. He slowly moved to
look over his shoulder, dreading what he'd see.
Yamamoto almost stopped and stared at them as he walked up - a momentary
slowing of his pace and a vaguely surprised look, and suddenly the arm Gokudera
had around Tsuna's shoulders felt twice as heavy.
"I stumbled," Gokudera said. "And. Then. I hurt my ankle! The Tenth is helping
me out!"
Yamamoto raised an eyebrow, and Gokudera's grip tightened round Tsuna's
shoulders as if in defiance. It didn't help Tsuna's blush to subside.
"Need support on the other side?" Yamamoto asked.
"No," Gokudera snapped, and began to walk with a limp that made it look like a
truck had hit him. Tsuna stifled a noise of surprise. "Why the hell aren't you
at your extra lessons, anyway?"
"Ah, well. The teacher seemed kind of stressed today ... he saw I was in class,
started to cry, and then he said I could go home." Yamamoto shrugged. "It's
nice to have more free time!" Gokudera was struck speechless at this, and Tsuna
snickered.
"So, are you guys going to do homework now?" Yamamoto asked, leaning his elbow
on Tsuna's shoulder - and Tsuna squeaked as Gokudera's hand gripped tighter,
digging into his arm.
"Yeah," Tsuna said with a sigh, at the same time as Gokudera said, "No, we're
testing my sister's new special cookie recipe."
There was silence for a beat. "Well..." Yamamoto's mouth stretched into a grin
that seemed inordinately broad even for him. "I guess this free time is a good
opportunity for some batting practise at Namimori Ball. I'm turning here,
then." He moved off, jogging away. "Have fun, you guys!" he shouted over his
shoulder before crossing the road.
They watched him go. "Did Yamamoto just wink at us?" Tsuna asked, feeling
light-headed.
"Yeah," said Gokudera. "He knows."
"I guess so."
Gokudera lifted the arm around Tsuna's shoulders and ran his hand irritably
through his hair. "That means I'm punching him next time he gets touchy-feely."
"Gokudera-kun!" He was on the verge of getting ticked off about those
ridiculous jealous tendencies, but then he saw that Gokudera had that look on
his face, where it was almost like the skin around his eyes had been bruised.
Tsuna's annoyance fell flat. "You know it's not like that. Yamamoto is just
that kind of person. Anyway, I ... wouldn't let it happen, if it were like
that."
The bruised look softened, and the corner of Gokudera's mouth eased out of his
habitual frown. It felt like an accomplishment, even if it was really easy.
Tsuna eyed Gokudera as they started walking again. His hands were jammed into
his jacket pockets, and now he was so relaxed he was humming softly, only a few
notes loud enough to hear over the sound of traffic. Tsuna was pretty sure
Gokudera had only bothered to put an arm around him in the first place because
it was the kind of thing Yamamoto did; Gokudera wasn't the physical type. He'd
been steeling himself to do it, judging by the way he'd acted all stiff ever
since falling into step beside Tsuna as they walked out of school.
It's just me. There's nothing to get so worked up about, Tsuna wanted to say,
but it wouldn't help because Gokudera wouldn't believe him. Thoughts like that
made him go hot inside, and then he'd end up staring at Gokudera. When he did
that, Reborn said the expression on his face made him look like a cow, and
usually threw Lambo at his head 'for the company of an equal'.
They were outside, so Tsuna didn't indulge in staring. He turned his smile to
the sidewalk and promised he'd get that look off Gokudera's face completely.
It turned out to be simple. At home, he found I-Pin and Lambo hurtling around
the living room and Reborn having coffee in the kitchen, so he didn't have to
search his room for napping babies before locking the door.
Gokudera was sitting on the floor, digging through his bag when Tsuna turned
around. "S-so, um, are you really in a hurry to start homework?" Tsuna asked,
and sat down what felt like too close to Gokudera.
"Oh," said Gokudera, turning towards him. "No ... if you want..."
"Yeah." He beamed; it didn't feel like he was too close anymore. Gokudera's
arms went round his waist, and he ended up almost in Gokudera's lap. He got
kissed so hard his back dug into the bed frame, and it felt like they weren't
close enough.
Handholding and stuff like that didn't come naturally to Gokudera, but when
they did this kind of thing he couldn't seem to get enough. Especially after
one of his jealous moments. Tsuna remembered the locked door with a giddy sense
of freedom and didn't hesitate in pulling off his shirt when Gokudera's hand
crept under it, and then Gokudera immediately yanked off his own blazer and
shirt. They'd hardly ever got that far, and somehow Tsuna was unbuttoning
Gokudera's trousers before he remembered embarrassment.
His fingers went heavy and clumsy. "Gokudera-kun, is it okay? If I - I haven't
done this before, so..."
He was relieved when Gokudera kissed him, because he couldn't think of anything
sensible to say. Then Gokudera's hands relaxed their grip on his hips and
unfastened his trousers too.
"Uh ... same here, Tenth," Gokudera said. "But it's, um, no problem. I'll
just..."
Gentle. It was a little surprising every time he was reminded how gentle
Gokudera could be. Tsuna leaned forwards and let their foreheads touch as
Gokudera got his boxers out of the way.
"Okay, then, me too." Tsuna steeled himself, pulled at the underwear and got
his hand wrapped around Gokudera's dick, and Gokudera breathed out in a hiss.
Tsuna started moving his hand and heard Gokudera swallow, and there was
thudding in his own ears as Gokudera began to move his hand. The angle was a
bit awkward, and the entire situation was suddenly very awkward. But he
couldn't breathe right, and he had his free arm around Gokudera and it felt
like they were locked into a private corner of the world, and so he couldn't
think of stopping.
Tsuna wanted to ask if it felt okay, or at least narrow down what he was doing
wrong, because he was pretty sure he was doing everything wrong. Everything.
Ever. But Gokudera was biting his bottom lip to keep quiet and looking straight
at the wall. It wasn't like there were instructions written there - Tsuna had
checked in desperation - so Tsuna figured the way to get through it was to keep
your mouth shut and more or less pretend that you weren't here.
Then Gokudera got a look on his face like he was under strain he couldn't take
and his head dropped. He buried his face in Tsuna's neck and they both jerked -
Tsuna because of the suddenness of it, and Gokudera bucking into Tsuna's hand.
Tsuna's fingers went wet, and Gokudera went soft, and it seemed like he could
feel exactly how red Gokudera's face was against the prickling skin of his
shoulder.
Tsuna almost quailed. It felt like such a lot, like a little too much. But he
couldn't move away while Gokudera's head was there, and there was still the
hand on his dick. It had stopped moving, but now it began to pump again, slowly
and firmly. Tsuna breathed deep and let himself move with the motion of
Gokudera's hand, and he exhaled with a weird, helpless sound. He felt the slide
of Gokudera's hair falling against his neck and chest, lighter than Gokudera's
breath and yet just as vivid a sensation; his stomach turned, and he hunkered
down as he came.
Gokudera breathed out in a long sigh like he was relieved. Then he looked up to
meet Tsuna's eyes.
Tsuna couldn't help it - he started laughing. Mission accomplished! he thought,
putting his arms around Gokudera's neck, feeling as Gokudera huffed out a laugh
too. The bruised look was gone; in fact, if Reborn had seen that expression, he
would have chucked Lambo at Gokudera's head.
