Summary
     Tony`s mind goes blank when he feels the plush pressure of Peter`s
     extended tongue and then the warmth of his mouth around his finger.
     He`s so thrown that he doesn`t jerk his hand away, doesn`t jump from
     the couch like he`d seen a ghost, doesn`t even feel angry.
     Peter mistakes the lack of rejection as approval and closes his mouth
     around Tony`s thick finger when he feels bold and flustered,
     eyelashes fluttering close while he relishes the moment of taste and
     touch. The dryness of the digit inside his mouth is quickly replaced
     by the lubrication of his spit, enveloping the slight saltiness of
     Tony`s skin.
     ---
     Alongside with superhuman strength and enhanced reflexes, puberty
     seems to change for Peter too. He realizes that strong emotion, like
     anxiety or arousal, makes him start to salivate intensely. Unable to
     discuss his problem with anyone without giving away his powers, he
     swiftly realizes he can only confide in Tony who`s unwittingly
     dragged into a flurry of pent up sexual energy by the name of Peter
     Parker.
Notes
     This will be part of a two-part series, so this isn`t the end. Don`t
     worry.
It`s a very complicated thing, being thrust into adulthood with the hormonal
changes it entails, all with a heaping helpful of even more uncertainty from
superhuman powers Peter had never wanted or asked for.
Much like how growth spurts ached deep within his bones, or the sprouting of
hair in areas previously smooth, the process of assimilating and maturing with
his powers presented itself an awkward and, at times, unsettling challenge.
This part of physical maturity he couldn`t relate to anybody else and he`d
started to realize early on that he no longer could identify what was regular
puberty and what was budding spider-powers or their consequences. In most
cases, it was uncomfortable and predictable, everything puberty was supposed to
be. Still, not everything was simple, not for Peter. Of all the embarrassing
things he could be mortified by, there was one thing that somehow he was d too
self-conscious to even look up online.
Around a month ago, he`d started noticing something very foreign happening to
his body. He`d noticed he had started to have intense salivation whenever he
felt too strongly about anything.
The first time he`d had an...episode, he`d freaked out. It didn`t help that
he`d been having an anxiety attack at the time, desperately rubbing his clammy
hands together in an attempt to ease some of the tension when he starts feeling
the spit suddenly pooling underneath his tongue so quickly he can`t speak
anymore. He tries to subdue his mounting terror, trying to keep his breathing
steady while he swallows (four? maybe five) mouthfuls of the thick spit, only
to realize he`s starting to get nauseous and has to rush to the bathroom.
It`s about seven full minutes before it stops, by which he`s kneeling before
the toilet with his mouth open over the bowl, drooling uncontrollably and
quietly sobbing, wondering why was this happening to him. He`d forcefully spat
a couple of times onto the side of the bowl, gauging if the attack had really
stopped as suddenly as it came, unannounced and unwarranted. When he`d gone to
wash his face right after, he`d licked his lips unconsciously as he idly
thought about how dehydrated he was.
He was so deeply ashamed of it, so secretive with its strangeness that whenever
he`d even think of telling somebody he`d start feeling the heat of shame and
the telltale sensation of increasing moisture behind his palate. It translated
to everything, he`d soon realized, although the intensity of these attacks
fluctuated greatly. As time passed and he grew used to thinking about it as
some sort of awkward and unavoidable developmental hiccup (like body odor or
morning wood), he hadn`t experienced as intense an incident like that first
time. Most days he found himself avoiding strong emotion anyways, definitely
sure that anger and anxiousness triggered the reaction somehow.
He knows he can`t talk about it to Aunt May; it would arouse suspicion
(although probably mostly concern) and Peter was pretty sure he couldn`t deal
with the scrutiny and the attention. He couldn`t exactly tell Ned either,
couldn`t really explain himself without revealing his spider-powers to his
friend, so that was a no-go. So, as he sulked miserably and tried to embrace
the idea that he was doomed to suffer in silence, a small glimmer of hope
suddenly crashes his thoughts.
Mr.Stark.
He`s sitting on the bed and he can feel a heated rush creep from his chest to
his shoulder blades at the absurdity of the idea. Mr.Stark was a grown man,
Christ, he was the man. He knew about his powers and he trusted him
wholeheartedly. Peter was fully aware of just how much he projected onto Tony
as a mentor, as a strong figure in his life capable of offering so much
opportunity and good fortune (and maybe a little bit more). As he delves deeper
into the rabbit hole, he can discern signs of another attack by the wetness
tethering on his tongue. This time, he`s not scared. Mr.Stark always looked so
good, Peter assumes it`s his enthusiasm that’s making him drool, the mental
image of Mr.Stark in his fitted suits and his suave attitude soon making him
hyperaware of his arousal and shame.
Aunt May had left to run some errands and it was Saturday afternoon. Peter was
alone in the apartment. When he crosses the room and clicks the door shut, he
swallows thickly, by the time he`s lying down on his bed he`s already hot and
hard.
Since discovering his affliction, he`d quickly realized that thinking about sex
was another thing that stimulated him right into an episode. He`d briefly tried
to renounce touching himself, hell, thinking about it all together just to
avoid feeling so helpless and weird when hiding all of this from everyone
around him. Still, at 16 years of age, it was very, very hard and he found
himself trying to find a time and a place where he could have some real privacy
and he could just let go and touch himself properly.
It barely came as a surprise that Mr.Stark was featured in this fantasy world
of heat and sex; He`d been obsessed with the man from the beginning, even
before he`d known about his interest and disposition to aid him through the
muddled mist of Peter`s new life and powers. Peter was already faint with
excitement, acutely aware of how his clothes brushed against his crotch, his
nipples. Since the beginning of his salivary ordeal, he`d put a towel on his
pillow, which he was grateful for as spit started to lightly pool on the sides
of his cheeks. He knows Aunt May was due to come home in a few hours so he was
free until he left for patrol, free to explore, finally-
He has a hand on his zipper when his cell phone rings.
The phone is far away, inside of his backpack right next to the door. He
seriously considers leaving it unanswered but eventually, he reluctantly
strides to sift through his things. His heart almost skips a beat when he sees
the name flashing on his screen.
"Mr.Stark," he says, meaning for his voice to sound curt and professional
instead of the pathetic squeak that actually comes out and he coughs. He clears
his throat and frowns to steel himself "Mr.Stark."
"Hey kid," he answers calmly, his raised eyebrow almost present in his voice
"Are you busy right now?"
Peter looks anxiously at his tented jeans and swallows, runs a hand through his
hair in exasperation even as he considers Mr.Starks` tight schedule. He knows
what his answer should be. "It depends." He says instead.
"All good?" Tony asks curiously. Peter wants to slap himself.
"Yes!" he manages to choke out "I mean- sure, I`m free."
"Great," He sounds pleased "Because Happy`s already waiting for you outside."
 
                                     ****

When they reach Stark tower, Peter is feeling only slightly calmer. He`s pent-
up and nervous, feeling wrong about what his body is doing to him. When he
steps into Mr.Stark`s penthouse he offers his hesitant greeting. If Tony
notices anything strange, he doesn`t mention it as he ushers him into the lab.
He`s waxing poetic about the modifications to the new suit he`s working, all of
the improvements and kinks he needs to work on, hat he wants Peter to maybe
help him out with today.
"Would you like to try it?" he says finally, snapping Peter`s attention fully
to himself for the first time since they talked on the phone. Peter smiles
sheepishly.
"Ah…I`m sorry, I didn`t quite catch that last part…" he says softly. Tony
quirks an eyebrow.
"Did you listen to anything I said?" he asks, no venom in his voice even if he
does seem slightly annoyed. "If you don`t wanna be here you can tell me, you
know? "
Even if it`s not flat-out rejection, or even scolding for that matter, Peter
panics, starts rambling anxiously about how sorry he is, that he`s distracted
but he wants to be here (God he wants to be here), starts feeling his heart
racing in his chest and the familiar weight of spit between the top of his
tongue and the floor of his mouth-
"We can reschedule." Tony says, patting him gingerly on his shoulder and Peter
feels like he wants to cry.
"I don`t want to reschedule," he says miserably, hating, hating himself when he
feels the viscosity between his teeth, making it hard to talk without slurring
"I want to be here."
"You`re no good down at the lab with your mind elsewhere," Tony answers simply,
squeezes his shoulder and that wounds Peter even tighter "Maybe you should take
some time off, blow off some steam. I could get Happy to take you-"
"I want to be here." He affirms once again, voice wavering and stunning Tony
into silence with how close he seems to be on the verge of tears. He looks into
Peter`s big, beautiful brown eyes with purpose now, trying to understand the
boy before him.
"Look," Tony starts, clearing his throat and feeling slightly uncomfortable
with all this sudden emotion "I know I`m not the best person to say this, but
if you feel some type of way then sometimes it`s better to talk.
You don`t have to tell me anything," Tony quickly adds "If you don`t want to.
Just…find somebody you can talk to. We have good counseling at Stark Industries
if you decide you need or want it-"
With every word coming out of his mouth, Peter feels more and more inclined to
yield, to tell him everything that`s been making him feel horrible and just get
it over with.
"Do you want to help me?" he interrupts Tony, voice small. Tony winces
inwardly, unsure if it`s the emotional moment that is making him want to flee
or the vulnerability of the boy in front of him.
"Only if you really want me to."
Peter`s heart is still racing, noticing they`re standing pretty close, the
weight of Tony`s warm hand still firm on his shoulder and a wave of arousal
almost makes him weak on the knees. How could he admit to something so shameful
and ridiculous as incessant salivation to a man that was so imposing and
intelligent and cool? He would never understand him, would he?
"It`s embarrassing…" Peter says now, looking into Tony`s eyes and regrets it
immediately because he`s studying him with a slight furrow in his brow like
he`s one of the kinks of a new suit that he wants to iron out.
"Growing up is embarrassing," He says now, voice light and conversational "You
should`ve seen me at your age, couldn`t even grow a proper mustache until I was
21."
Peter allows himself a little smile at that.
"I think this is a little different than that," He mumbles "And I don’t know
how to effectively put it into words, either."

"Well, I`m done for the day and I`m not in a hurry… Although I did want to show
you some of the tweakings I`ve done to the new suit, although I don`t think it
would be advisable to suit you up right now," Peter is thankful for the insight
and nods "Would you like to go up to the apartment?"
Peter says yes and he walks silently beside Tony, who`s once again talking
about technology, and Peter really wishes he could focus because what he`s
saying is honestly so interesting but he`s too distracted. He finds it
difficult to think over the sound of blood rushing through his eardrums, he
realizes, suddenly seized by a primal fear that he will be rejected, maybe even
insulted by an afflicted Tony.
Stress must`ve been written all over his face because suddenly Tony calls him
out on it "Hey," he says, placing a hand on his shoulder again "Snap out of
it."
"M`sorry." He mutters back.
Once they arrive at the main floor, Peter saunters off towards the spacey
leather couch while Tony paces towards the minibar. Once there he calls Peter.
"Do you want something to drink?"
"I`m not old enough." He responds blankly, to which Tony rolls his eyes.
"I meant soda or water, genius," He clinks two glasses against the granite
countertop "Although I only have mixers and chasers here."
"Water would be fine."
While Tony fixes their drinks, Peter starts getting fidgety. When Tony sits
next to him and hands him his glass, his fingers brush against each other and
Peter begins feeling hot again.
Goddamn it.
"Ok," Tony takes a hearty swig from his scotch, fiddling with his phone until
some mellow music starts playing in the background "Tell me what`s going on."
Maybe it`s the shame he feels at the idea of drooling in front of another
person or how close they are that`s making him insufferably aroused, but
suddenly Peter has an idea. It`s probably a dumb, stupid idea, but his mind is
clouded as is his judgment.
"I could show you," Petter says, looking coyly into Tony`s eyes "I don`t know
how to explain it properly with words, but I could show you."
Tony`s interested is piqued, albeit unsure "I guess I could do that, if it
makes you feel better."
"Do you trust me?" Peter tries, almost smiles when Tony looks at him with
exasperated eyes.
"Peter…" he warns, unwilling to pander to this particular attention seeking
tactic.
"Okay, I know," Peter then shuffles a little closer "Close your eyes."
Tony is thrown off by the request and he shows it in the way his eyebrows
gesticulate. Peter absentmindedly notices how expressive Tony`s face is "Why
would I do that?" he asks.
Peter looks bashful "I don`t want you to see it, just feel and understand what
I mean," It`s after the words leave his mouth that he realizes the
implications, almost chokes himself on the barrage of words he can`t stop
tumbling from his mouth "Oh god, that sounded horrible, I swear it`s nothing
bad, it`s only embarrassing and I don’t want you to be disgusted or anything, I
just don`t know who to talk to about it and it`s hard-"
"Peter..."
"And I can`t tell May because she doesn't even know half of the story and oh
God, I knew this was a bad idea, I think I should leave, Mr.Stark-"
"Peter!" Tony raises his voice, enough for Peter to stop in his tracks. "Jesus
Christ, kid, relax. I`ll close my eyes, just stop talking so much…."
He closes his eyes with creased brows, almost reluctantly allowing himself to
play this beautiful boy`s game even if there are red flags waving at the back
of his mind. Peter feels anxious and unfairly hot in his skin. He cautiously
waves a hand in front of Tony`s face and when he doesn`t react, he looks down
to his own crotch. It`s almost impossible to ignore how painfully hard he is,
being so close and within Tony`s living quarters, so he takes the opportunity
to readjust himself.
He would later attribute it to how delirious he feels with arousal and
frustration, but he decides that maybe logical thinking wasn`t going to help
him get what he felt he needed. The original plan was to let Tony poke around
the inside of his mouth, in a completely non-ambiguous, innocent way, to feel
for himself how saliva welled from the crooks of his molars to the grooves of
his incisors, at least before he let him open his eyes. He rationalizes that
the change of plans must be innocent enough; Tony Stark wouldn`t fall into
something so blatant.
Would he?
So he decides to try it out, tentatively touches Tony`s hand - to which he
stiffens slightly- and singles out his index finger.
"Peter?" He asks when the soft puffs of warm air brush against his fingertips
and knuckles "What are you-"
Tony`s mind goes blank when he feels the plush pressure of Peter`s extended
tongue and then the warmth of his mouth around his finger. He`s so thrown that
he doesn`t jerk his hand away, doesn`t jump from the couch like he`d seen a
ghost, doesn`t even feel angry.
Peter mistakes the lack of rejection as approval and closes his mouth around
Tony`s thick finger when he feels bold and flustered, eyelashes fluttering
close while he relishes the moment of taste and touch. The dryness of the digit
inside his mouth is quickly replaced by the lubrication of his spit, enveloping
the slight saltiness of Tony`s skin.
Carefully and horrified, Tony opens his eyes to see the sight before him;
Peter`s face is a lovely shade of pink, his lips shiny from saliva where they
stretch around him and Tony can`t believe he can`t unglue himself from his seat
when Peter hollows out his cheeks.
"Peter…" he whispers, can`t help the sharp stab of white-hot lust that shoots
to his groin at the sensation of the scorching mouth encompassing him "What are
you doing?"
Peter opens his eyes in a daze, slowly opens his mouth to release the intruding
digit and Tony...Well, he`s helpless to say anything as he sees saliva clinging
to Peter`s lower lip before dripping slowly, almost sensually, down his chin.
For all his degrees, for all his intelligence, Tony can`t articulate why he`s
letting this happen.
"Whenever I feel…a certain type of way, this happens," Peter says, opening his
mouth illustratively now as Tony marvels at the now thick streaks of spit
dribbling down his chin "And I don`t know if there`s something wrong with me,
but I think it has to do with," he wipes his mouth with his wrist "My powers."
Peter wouldn`t consider himself a people`s person, but even he could realize
that Tony was stunned into silence, the way he was looking at him with muted
hunger behind his eyes that made Peter feel powerful. Like he had something
that Tony Stark wanted that he couldn`t get without Peter`s help. It was
exhilarating.
"Mr.Stark?" he asks, breathy in a way that Tony`s heard before but can`t quite
pinpoint when "Are you mad?"
"Mad?" he exhales, finally, runs his dry hand through his hair "Christ kid, you
can`t go around doing this kind of things…"
It`s not fair…
Maybe it`s the heat tightening across his chest and groin, but Peter pushes
further "What do you mean?" he says, innocently at face. Tony almost believes
him, too.
"You know exactly what I mean." he rumbles his answer, voice husky and
traitorous.
Then Peter gathers the courage to close the distance between them with a kiss.
At first, Tony doesn`t correspond, going tense and unmoving as Peter licks his
lips shyly, sweetly.
"Don`t do this," Tony mumbles thickly, hands on Peter`s shoulders and pushing
him away lightly. "Don`t do this to me."
Please.
Peter is too far gone to gauge the situation, something that makes him
impulsive and Tony weak. So when he crawls onto his lap to straddle his thighs
and presses his hands on each of Tony`s shoulders, Tony places his warm palms
onto his sides and meets the scorching heat of the boy`s tongue. Peter`s
restless under his grip and so beautifully eager that it makes Tony`s heart
ache, feels the boy when he grinds down on him with a pretty whine, already
completely hard for him. Tony finds himself yearning for the touch,
absentmindedly basks in the attention and the warmth of another body, finally-
"Make me stop," he whispers wetly against Peter`s cheek, eyes big and imploring
when they meet Peter`s own "Please make me stop."
He`s rewarded with a hand between his legs, groping him because he`s already
hard through the fabric of his rugged jeans. Peter tilts his head to one side
"Why would I want to?" Tony exhales forcefully, aggravated but so turned on, to
which Peter smiles coyly "I`ve been waiting for this to happen."
Tony doesn`t answer, tries to look away when Peter slides between his thighs to
kneel before him. He fumbles with the buttons of his pants, clumsy and
inexperienced and Tony would be mortified if he didn`t feel like his heart was
about to give out.
"You`ve imagined this scenario in your mind?"
Peter`s whimper almost makes all of this seem worth it "So many times…" he
murmurs when he palms Tony`s thick cock outlined from the confines of his
jeans, swallows a mouthful of saliva from the sight alone "To think you`d want
me like this, too…"
Tony actually looks away at the last comment, almost sure Peter hadn`t meant to
say it out loud. He feels Peter`s hand engulfing his clothed member with virgin
hands. He starts rubbing against and Tony can`t help the small groan that
escapes his throat when he feels Peter nosing at the fabric like he wants to
peel it off that way. He places a hand on Peter`s cheek tenderly as he swallows
bitter remorse and decency, looks through the thick eyelashes into drowsy
bright brown eyes "Stand up." Tony says but he doesn`t sound moralistic, so
Peter stands up. Peter`s manhandled onto Tony`s lap with his back flush against
the man`s chest and everything feels hot and tight and wrong.
Peter closes his eyes forcefully when he feels Tony`s mouth on his neck,
traveling down his shoulder while his hands roam from the divots of his sides
to the expanse of his thighs. He lets out an almost pained sigh when broad
hands lightly squeeze around the pressure in his pants, only to massage his
legs and bite his neck wetly. Peter feels the bubbling panic when he feels
saliva filling his mouth, Tony can hear it when he tries to speak "I`m starting
to- Mr.Stark- " He can`t elaborate when two thick fingers slide into his mouth,
making his saliva drip from his lips and he moans when pressure from Tony`s
other hand touches his erection more firmly now. He tightens his ass
reflexively only to feel Tony`s hard cock against the line of his ass and he
starts drooling now, rocks himself harder against the man. He`s rewarded with a
surprised, drawn-out hiss.
"I want to make you feel good," Peter says, a slurry of words around Tony`s
fingers that are sliding in and out of his mouth, against his fluttering tongue
and it`s too much. It makes Tony wrap an arm against Peter and hold him tightly
with a curse, stilling both of them in that position.
"You don`t know what you`re doing to me, kid," he breathes, possessive and
dazed while he pants against his neck. He`s so screwed now, he knows that, head
swimming when he has this beautiful boy willing in his arms and he regains some
composure in their stillness "I`ll get you off but you have to leave right
after," Peter stiffens "Promise me."
Peter is disappointed but too consumed by his need to come now that he nods his
head desperately, throws his head against Tony`s shoulders when looking for a
tighter fit "I promise."
Tony gropes him firmly at that, right hand holding him over his pants and
places his fingers back into the wet heat of his mouth. Peter keens, rocks
himself steadily against him until Tony squeezes his thigh to make him stop,
afraid he`ll come in his pants like a goddamn teenager himself at the
desperation of this pretty boy against his body. When he opens the zipper of
Peter`s pants he`s met with a strangled moan, one that turns into a heady sigh
when his hand envelops his cock. He knows Peter is so close now, feels how his
dick is throbbing under the pressure of his fist and he pulls the velvety
length slowly. Peter`s moans are honey to his ears, saccharine and cloying as
they vibrate against the digits fucking into his mouth. He pulls his fingers
out with his palm covered in viscous slick and he puts in on the boy`s cock,
making him curse, swirls his palm over the head once, twice, and the boy is
twitching helplessly, shooting his load warm and wet onto Tony`s hand and his
own shirt.
The boy remains still, breathing ragged and overworked while Tony eases his own
mind by unthinkingly peppering kisses into his neck, wipes the come on his
jeans that were stained with oil anyway. Peter sighs as Tony tucks him into his
boxer briefs and pants, again embarrassed but drunk on the post-orgasmic bliss.
They stay that way for a solid two minutes until Tony can collect himself.
"I think you should take a shower," he tries to comment carelessly, but his
voice comes out hoarse and his throat is so dry. He coughs a few times "I have
a tub if you wanna have a bath and there are towels and clothes that may fit
you if you need them."
Peter feels sated but disappointed because he can still feel Tony hard against
his ass, and he un-sticks his back from its place against Tony`s chest "You`re
still hard," He says simply even if he`s mortified while saying it, even after
what they’ve just done. Tony frowns at that, taps Peter`s thigh from the
outside to make him stand up, which he reluctantly does. "I just want to-"
"You promised you wouldn`t push it," Tony tries to say imposing, hates that he
sounds displeased and unfulfilled even in his determination "So don’t push it."
Peter wants to cry now, feeling rejected and hurt "Okay," he answers instead of
arguing further. He`s scared he`ll start to tear up "I`ll go shower now."
Tony should`ve probably shown him the way to his bathroom himself, he knows
that, but can`t possibly face the music so he calls out "F.R.I.D.A.Y," The AI
greets him with its computerized voice "Show Peter where he can take a bath,
where the towels are and all of that jazz."
Tony could swear he sees Peter wince as he turns his back and follows the AIs
instructions. When he`s out of sight, he mutters at F.R.I.D.A.Y "Delete the
footage from the past hour."
After a few seconds pass, the voice answers "Done."
