He snorted at that, but he did reach out to curl a hand in Naruto's hair.  It gave him a
feeling of control that he needed right now.  He really didn't think he'd be able to watch
Naruto do this.  With his mouth.  Not to mention what he was going to do with his other
hand.  He took a long breath, calming himself as much as possible.  His chakura control
wasn't the best, but he did have good control of his body.  Usually.  Naruto curled his
dry hand around the base of his erection and it was all he could do to keep his legs
frozen in place.  His stomach flexed instead.  Heated blue eyes flicked up, catching his
gaze, holding it, forcing him to watch as Naruto lowered his head slowly.  All of his
earlier revulsion surged forward the closer Naruto got.  He couldn't believe he was
seriously going to do that.  He watched his mouth open, his tongue wetting his lips, and
then it touched the tip of his erection and he heard a small involuntary sound escape his
throat.  He recognized it as a protest and was glad he hadn't been able to form it into an
actual word.

Naruto twisted his hand, stroking him in a feathery grip that was more tormenting than
pleasurable.  Sasuke clenched his teeth and glared silently into laughing blue eyes.  
Teasing him.  Then Naruto dipped his head and took the tip of his erection into his
mouth without breaking eye contact.  Sasuke blanched, choked, and almost came off the
bed.  Naruto applied suction and he made a strangled noise in the back of his throat.  If
he hadn't been horrified and aroused, he would have been humiliated to know that noise
came from him.  His free hand clutched and fisted the sheet beneath him.  The hand
he'd curled in Naruto's hair jerked faintly, torn between letting him continue and pulling
him away.  He was suddenly terrified he'd cum in Naruto's mouth.

He let out another muted, strangled sound that couldn't be classified as a groan.  He
tugged on his hair.  "Naruto..."

Burning blue eyes glinted at him and Naruto lifted his head.  Sasuke kept his own eyes
locked on Naruto's.  He wasn't willing to look at the saliva glistening on himself.

"What's the matter?"

"I almost-"  He grimaced and stopped.  He couldn't even say it.  He didn't need to.

Naruto's eyes widened slowly.  Then he smiled in sly, pleased way that made Sasuke
distinctly nervous.  "It's okay to come, Sasuke.  That's the whole point."

In his mouth?  His expression must have reflected his horror, because Naruto read the
question and dismissed it.

"I told you I don't mind," Naruto said lightly, his head tilted so he could lap at Sasuke's
erection before continuing.  He smirked when Sasuke flinched at the contact.  "I want
you to.  I want to be the reason you did.  And it'll make the rest easier.  Trust me a little,
will you?  I do know what I'm doing."

"Can't you just...do it without that?" Sasuke demanded.

Naruto sighed.  He was eyeing his erection sadly, with blatant disappointment, as if it
were a prize about to be taken away from him.  Sasuke had a sudden urge to hit him
upside the head.  He twisted his hand instead, tightening his hold on Naruto's hair so he
winced.

"Okay," Naruto grimaced, "you win.  But...next time?"  He flashed a hopeful, almost
woebegone look at Sasuke.  "You have to let me do it at least once or else you can't
really say you tried it, right?"

"Next time," Sasuke agreed.  "Not now."  That would give him a chance to come to
grips with the idea.  As it was, he couldn't stand the thought of Naruto doing that to him,
for him, when there was no way he'd be able to do it himself.  Then he really would feel
like a coward.

"I'm holding you to that," Naruto said, in what came out as a stubborn pout.  He leaned
forward to frown at Sasuke.  "Now I can't even kiss you while we're doing this.  I'd say
you owe me.  I'm gonna take it out of you in hickeys."

"What?"

"Hickeys," Naruto said, in a very serious tone.  "Red marks about the size of my mouth
where blood pools beneath the surface of the skin due to prolonged suction.  You'll like
it."

Sasuke's mouth dropped open just as a slick finger brushed against him.  He snapped his
mouth shut before a startled sound could erupt.

"Tell me if it hurts too much."

"I'm not going to break," Sasuke said scathingly.  He still wanted desperately to hit him
upside the head.  That would be childish.  Immature.  He'd never shame himself by
doing something like that.  It would be sinking to Naruto's level.  He really wanted to do
it at least once.  Hard.

The finger slid into him, a faintly burning, uncomfortable sensation.  Sasuke was
abruptly distracted by a similar burning on the side of his neck where Naruto had latched
onto him with his mouth.  He glowered at the ceiling.  Put into perspective, the 'hickey'
hurt more than the finger did.  Naruto pulled his mouth free with a wet popping noise.  
Sasuke retaliated by twisting his hand and nearly ripping a fistful of that blonde hair out
by the roots.  He was rewarded by a choked whimpering sound right in his ear.

"I was distracting you," Naruto pouted, when he'd lifted his head enough to look at him.  
"You don't have to be violent about it."

Sasuke stared at him through narrow red eyes.  Naruto bore a moment of that stare
before cracking.

"Okay," Naruto said quickly.  He gave a weak grin.  "I'm sorry for playing with you
when I've got a fi-"  He stopped, looked wary for a second, and then tried again without
the grin.  He somehow managed to look entirely serious.  "I'm going to do it now.  I'll go
slow, but it'll still feel weird at first.  You're good at relaxing, so it shouldn't hurt much.  
Tell me if it does and I'll stop."

"Just do it," Sasuke muttered.

At this rate he wouldn't even be aroused by the time Naruto got around to the actual sex.
 He leaned forward enough to watch Naruto slick himself with more of the cream.  
Oddly enough, after watching Naruto use his mouth, this part wasn't as disturbing.  
Sasuke frowned and shifted his legs into a more comfortable position.  Naruto glanced
up, giving him a strange, considering look.

Sasuke froze, "What?"  Naruto was the one who'd told him to watch.

"You're not embarrassed?" asked Naruto.  He leaned forward before Sasuke could
answer.  "If you're not too embarrassed, the easiest way to do this your first time would
be for you to lower yourself onto me.  That way you can wait for your muscles to relax
and do it at your own pace.  If you're too embarrassed, that's fine, but-"

"How?" Sasuke demanded.  "What do I do?"

Naruto beamed at him and leaned forward.  He caught himself at the last minute and
pressed the kiss on Sasuke's cheek instead of his mouth.  "Trade places with me."  They
repositioned themselves so that Naruto was leaning against the headboard with Sasuke
kneeling over his hips.  Naruto pulled his arms so he was braced on his shoulders and
gripped Sasuke's hips to support him.  "Just go slow.  Don't get impatient and hurt
yourself."

Sasuke blocked him out.  He positioned himself and lowered and immediately met
resistance.  He'd loosened the muscles he had control over.  This was an involuntary
one.  He understood what Naruto had meant about waiting.  Twenty seconds and it
relaxed on its own, unable to remain contracted any longer.  He pushed and grimaced at
the burning pressure.  It didn't hurt, but it didn't feel good, either.  It felt strange,
unnatural.  If it felt like this when he did it to himself, how bad would it have felt if
Naruto had done it to him?  He continued down, letting out a quiet breath when he was
fully seated.  And he realized, belatedly, that Naruto must have been staring at him the
entire time.  His head snapped up, a humiliated blush already blooming on his face.  He
was disarmed by the look Naruto was giving him.  A hand lifted from his waist, brushed
his cheek, and pulled him into a soft kiss.  He forgot why Naruto wasn't supposed to
kiss him.  It didn't distract him from the sensation of being stretched and full and
uncomfortable.  But it rid him of the self-disgusted blush and he was glad to have that
gone.

Naruto shifted the kiss to his neck, nipping and sucking and probably leaving another of
those marks, judging by the burning sensation.  Sasuke rested his forehead on his
shoulder and let him.  He was starting to wonder if it might have been better if he'd
come earlier.  Not in Naruto's mouth, he still wasn't ready for that.  But he would have
had an easier time being patient if he'd already finished.  A hand curled around his
erection, giving a tentative stroke.  Sasuke muffled a groan against Naruto's shoulder.  
He'd clenched around that length and been reminded of exactly how deep in him Naruto
was.  He'd never felt anything like this steady discomfort.  He wanted it over.

"You can move," Naruto murmured, still kissing his way along his neck and shoulder.  
He turned his head, breathing against Sasuke's hair, as if the scent were intoxicating.  
"Find a position that suits you."

"I don't want to move," Sasuke muttered tensely.  He decided Naruto was simply too
deep in him.  He'd waited a few minutes now and it seemed to be getting worse instead
of better.  It didn't burn as much, but the pressure was starting to hurt his stomach.  He
couldn't stand the thought of moving, of possibly driving him even deeper into him.  
What if it did permanent damage?  It was possible.  His body certainly hadn't been
designed for this.  He pushed his forehead harder into Naruto's shoulder.  "Can you tilt
me back?  There's too much pressure like this."

Naruto lifted him up a little, and Sasuke groaned in relief.  Definitely the pressure.  He'd
have to make sure to switch positions immediately the next time they did this.  Naruto
lowered him carefully on his back and the movement inside him brought another groan
to his lips.  A good one this time.  Naruto started to pull out more and he caught a hand
in his hair, the other on his hip to hold him in place.

"I didn't say stop," Sasuke muttered.  He opened his eyes to glare blearily at him.  "Are
you in that much of a hurry to quit?"

"I don't want to hurt you."

"You didn't.  It was the position.  I stayed in it too long."  He shifted tentatively and
pulled Naruto closer.  "This is better."

"Are you sure?" Naruto frowned.

He looked stricken, concerned, guilty.  Sasuke marveled at the irony of having to be the
one encouraging Naruto to finish what he'd started.  It finally felt good and now he
wanted to stop?  He gave a pointed glare, "Do you really want me to change my mind?"

Naruto looked at him for a long moment and then shook his head decisively, "No."

"Then move."

He did, entering slowly until they were flush against each other.  He leaned down and
pressed a light kiss on Sasuke's mouth.  "You're eyes are black," he said.  He gave it like
an apology.

"I was distracted," Sasuke muttered, defensively.  He was taking it as an insult.

Naruto lifted his legs so they were braced on his arms, changing the angle slightly.  
When he moved it was at the same slow tentative pace he was stroking Sasuke's
erection.  Pleasant, but not enough to accomplish anything.  Sasuke pushed his hips up
to meet him and caught his eye with an unsatisfied glare.  It came out red.

"You said you would hurry," he reminded him.  "Do it.  You're not going to break me."

Naruto scowled at him for a moment and then gave a hard angled thrust that sent a
shard of something besides semi-pleasant friction through him.  Sharp, intense, entirely
unexpected.  Sasuke let out a cry, too shocked to be embarrassed.  He choked back
another when Naruto did it again.  By the time Naruto settled into a fast rhythm, he had
a fist pressed over his mouth to keep the sounds in.  He tried to glare at him for not
doing this sooner, for not telling him it would feel like this.  He suspected it came out
more as a glassy-eyed stare.  He couldn't tell if he still had the sharingan activated or
not.  Naruto was stroking his erection too hard, too loose, at odds with his steady
thrusts.  Clearly, he was having just as much trouble focusing.  He was also making
more noise than him.  Sasuke supposed that was because Naruto didn't have any free
hands to sink his teeth into.  He was still louder.  And that blue-eyed scowl was every bit
as dazed as Sasuke felt.  Then Naruto was pulling his hand away and covering his
mouth with his own and he couldn't have said which of them finished first.  He didn't
care.  It didn't affect the aftermath.
