Summary
     Because I have a weird brain, I wanted to try writing smut, and I'm
     weird but I ship Hiro and Baymax a little okay
     Robot sex. I am ashamed.
     *first time writing smut :
POINTLESS SMUT
 
His breath is hot where it hits his face, puffs of it bouncing off where he
presses his face into the mattress and he arches – arches up –grasps
desperately at the pillowcase and the bedcovers and his hand slicks, smooth,
from where sweat is collecting at the base beneath his balls and up to where he
digs his thumb into his slit. A bead of precum dribbles out and Hiro doesn’t
stop himself from sucking it off his own fingertip, a scandalous little slurp
that almost guiltily sends a thrill down his spine.
Crazy. He doesn’t even know what got him so fucking horny in the first place,
just knows that between the moment where he lied down on his bed and when he
began curling a fist around his dick that all he wanted was to let go, let
loose a little bit. Hiro’s still just a kid; a defenseless little clueless kid
who’s got a man in a weird freak mask trying to kill him, so nobody can really
blame him for being just a little high strung and just a little desperate to –
ahh, yes, mmm ohthatwasnice –relax.
Hiro lowers his hips, traps his dick between his stomach and the cool, cool
sheets, and ruts against the mattress. His hips bounce up, fall down, and the
heat on his stomach with the softness beneath him feels so good and he couldn't
stop a long, low moan spill from his lips. Uhnnn.
“Hiro? I heard a sound of distress,” a disembodied voice says to his right,
“what seems to be the trouble?”
Oh god. Hiro freezes in alarm. His hips descend on the mattress once more, his
cock rubbing sensuously against the cloth, and he buries his face in his pillow
to muffle a groan. “B-Baymax,” he fights to keep his voice steady, even while
 his dick twitches anxiously,  “what do you want?”
“You are emitting sounds of distress,” and, bless him, Baymax looks like he was
trying his best to understand, “I am here to help.”
Hiro watches him grab the edge of the blanket and start pulling it off, and –
no way is that happening. Hiro twists, lurches upward, and yanks it back firmly
over his groin because yeah, Baymax is a robot, but he’s also like a clueless
kid and this is seriously not happening to Hiro right now.
“N-no, I’m completely fine!” he laughs, and pulls the covers tighter around
him, “Just - just go back to – “
“On a rate of one to ten,” Baymax continues like he didn’t hear Hiro at all,
and with one swift tug the blanket falls to the side of the bed. That’s bad,
really bad, but the feeling of shifting cloth across his cock was kind of too
irresistible to not enjoy just a little bit and another moan bursts out of his
lips. Baymax remained unfazed, “how much does it hurt?”
“I – no – zero! It doesn’t – “
“Does it hurt when I touch it?” Baymax says, and Hiro scrambles up to the
headboard before Baymax’ balloon finger prods at him because this is just too
weird, and Hiro has read enough hentai to know where this is going. Maybe if
he’s fast enough he can run to the bathroom and finish his business there where
Baymax couldn’t possibly follow him? Should he give it a shot?
 “N-no, no, that’s okay,” Hiro puts a foot on the ground, “no touching – “
“It is alright to cry. Crying is a natural response to pain,” Baymax says, and
Hiro feels an electric tingle go up from his balls when rubber squeezes around
his shaft, and he keens sharply and – oh god he almost wishes there was more
motion on his dick but right now he knows he’s just being given a diagnostic.
Baymax is so huge that his hand just covers Hiro whole, and Hiro really
shouldn’t be finding that really hot but the thought of being under someone so
big is making his head spin.
“You have no injuries,” Baymax continues, “however, your hormones and
neurotransmitter indicate that you are experiencing arousal common in
adolescents,” and – oh, there it is, just the slightest squeeze – “diagnosis:
puberty.”
“Y-yeah thanks Baymax,” Hiro laughs, jittery, and for having balloon fingers
Baymax has quite the grip because Hiro’s having a tough time prying him off,
“don’t worry about it. I can take care of it myself. Haha.”
“I am your personal healthcare provider,” Baymax drones, “I will help you.”
Wait, what?
“Baymax,” Hiro tries, but Baymax’ fingers curl tighter around his cock and
gives him a solid pump that makes his head throw back and his hips lift up for
more. Okay, that was nice, but there’s something wrong about this that Hiro
can’t really place so he tries again and, “Baymax wait –“
“I will cure you, Hiro,” Baymax responds a matter-of-factly, “you need only
relax.” His other hand darts out, grasps Hiro’s balls in a loose fist, and his
other hand thumbs the head of his cock with velvety friction that turns Hiro’s
legs into jelly. Hiro doesn’t know what to do, but the pleasure is too good to
give up and…he won’t do it again, he promises himself, but as a bonafide
robotics nerd he’s got to know how this feels at least once.
So he shifts around, lets himself be nudged into lying back onto the bed, and
tries not to focus on the feeling of balloon fingers flitting all over him.
Baymax seems to know what he’s doing, and Hiro tries not to think of how
Tadashi could have programmed him to know so much.
Hiro pants, little short breaths, and feels his hands close into fists. What
was he supposed to do with them? Hiro lets himself reach up his chest,
searching for any hotspots he can discover, until he finds himself playing with
his nipples. He’s never really had a chance to play with them when he was
jacking himself off, and the new sensation makes his body light up – and okay,
he sorta feels harder than he did before. He gasps when Baymax tugs on his cock
and his balls at once and it feels good, so he swallows around the lump in his
throat and mumbles, “d-do that again. Please.”
Like clockwork Baymax complies, and Hiro pinches his nipples at the same time
and god, that was hot. He’ll probably have to clean Baymax later, by how much
precum he feels is dribbling out of him right now. Baymax is still surprisingly
gentle, careful, and that’s great but Hiro can’t really get off from that.
“Harder, Baymax,” he pleads, and tries not to berate himself for sounding so
needy.
“I do not want to hurt you, Hiro.”
What? Hiro doesn’t stop a whine from bubbling up his throat, and he squirms
around to find harsher friction, “Baymax, Baymax please. Do it harder.”
Baymax pauses, and Hiro could almost swear that he was performing a scan of
some sort. But Baymax returns to pumping his cock, with more strength in his
palms, and the sensation of being engulfed is delicious. Hiro brings a finger
to his mouth and sucks on it with ferocity, saliva dribbling out of his mouth,
down his neck, where he catches it on his other hand to swirl around a stiff
nub. He lifts his leg, reaches down and circles his entrance with a wet
fingertip.
“Hiro,” Baymax says, and Hiro finds the hand on his balls gone and rubber
fingers prodding his mouth, “you will hurt yourself. My fingers are far
softer.”
“Yeah but I need to stretch out first,” Hiro breathes out, but he sucks in
Baymax’ finger in his mouth anyway and slobbers all over it, laving his tongue
and enjoying the taste. Maybe if Baymax was human he’d be as thick as the
finger in Hiro’s mouth. Maybe if Baymax was human he’d be moaning wantonly too
everytime Hiro sucks a little too harsh and licks too delicately. Maybe Baymax
would come with a shout, thrusting deep into his throat until he gagged, throat
convulsing around an impossible girth. Hiro would slurp all of it up, savor it
as it leaks out of him, would let it dribble out of his mouth, and – if Baymax
was human – he’d reach up to kiss him and share the taste.
Baymax would still be gentle, if he was human. Hiro imagines being fucked open,
slowly, his ass stretching to accept Baymax’ girth, tight around him until
Baymax’ human form bursts hot seed inside of him. Maybe Hiro would wear a
buttplug to keep his cum in, rubbing inside him even while they were fighting
the bad guys, then at night come back to be fucked raw, again, and again, and
again.
“Hiro,” Baymax reminds softly, and Hiro pulls out his own fingers from his ass
and releases Baymax’ finger from his mouth with a wet ‘pop’. He grasps his ass
cheeks and pulls them apart, the cool air caressing his hole and his cock folds
back towards his stomach. A bead of his own precum lands on his stomach and
Hiro has never been so hard.
“Baymax, Baymax come on, Baymax –“
“Wait, Hiro,” Baymax says, and looking every bit the gentle giant he is, he
lifts Hiro’s hips and puts a pillow underneath it. “Are you comfortable?”
That was so characteristically Baymaxthat Hiro laughs, because only Baymax
would still be so gentle through this.”Yeah,” he answers, “get on with it
Baymax. I need this.”
But Baymax was still being slow, and careful, and he pries Hiro’s legs further
apart. His other hand is still on Hiro’s cock, pumping softer, more of a
reassuring presence than anything. “Remember to breathe,” Baymax reminds, and
Hiro tries to respond but a blunt, rubbery finger is already pushing into him
and steals his breath and he hasn’t felt this filled, ever. It feels warm,
smooth and soft yet firm at the same time, almost like a real dick inside him,
and Hiro gyrates his hips just to get a little more of it inside.
Baymax crooks his finger, searching, until Hiro arches with a yelp because –
did he just see fireworks behind his eyelids? Baymax starts thrusting,
measured, steady, and Hiro tries to recall the more complex geometric equations
because he’s going to burst with how Baymax is hitting his prostrate every.
Single. Time. The damn bastard has probably gotten the angle calculated and
saved into his hard drive.
“Baymaaaax,” Hiro groans, and he rotates his hips, makes Baymax grind into his
prostrate with a firmness that sends stars shooting behind his eyelids. The
sensation sends Hiro yelping, and he does it again, and again, and he sees
white cloud the edges of his vision. “Faster! Please!”
Like clockwork Baymax complies, squeezing and thrusting and pulling all at
once. Hiro lets his hands wander all over his body, stroking and pinching his
nipples and kneading his stomach. In one last bid he lifts his leg, hooks his
ankle behind Baymax’ head, and pulls himself down to take Baymax deeper and –
“BAYMAX!”
Baymax strokes him down from his high, thrusting slower and shallower. Hiro
sleepily watches his cum drip down Baymax’ fist, pooling into the dip of his
stomach. His body felt like jelly, one big lump of goop ready to sink into the
mattress. He reaches down, swipes a finger in the spot between Baymax’ hand and
his balls, and licks his juices into his mouth.
“On a scale of one to ten,” Baymax says, after a few moments, “how effective
was the cure?”
