Summary
     Teen Groot is full of lust and love for his mate. To be fair, Rocket
     would feel a whole lot less guilty about all of this if the Flora
     Colossus were fully grown.
Notes
     Groot is mentally an adult but his body hasn't matured yet, so I
     don't know if that makes him an actual teenager or not. Oh well.
Rocket heard the soft, heavy footsteps nearing the rec room door, even over the
clinking of his tools. He didn't need to glance over his shoulder to know it
was Groot. He could hear any of his teammates come from the other side of the
ship; sometimes he heard their mood in the pace and punch of the steps. But he
could especially tell if it was Groot. It was a shift in atmosphere. Rocket
pushed his goggles to his forehead and squinted at the device Peter had asked
him to fix. The human had tried it himself at first, but as usual, only made it
worse. How Quill had survived so long without a genius like him, was beyond
Rocket's comprehension. He felt Groot's weight on the floor next to him, the
sweet fresh scent the young Flora Colossus produced. Groot was getting big. He
had been Rocket's height a week ago, and now he was 12 inches taller than him.
And sturdy. He had started out so tiny and slender; then he had been alarmingly
gangly for a week, like a bean pole. Now his skin had started to harden in
large patches, become darker in color, the tendrils on his head stiff and
broad, wood-like. Groot leaned down and pressed his face into the back of the
raccoon's ear, nibbling it gently. Rocket's muzzle twitched with effort, but he
grinned anyway.
The Flora Colossus had always been affectionate, but after his rebirth,
especially so. The moment the potted sapling had first opened his eyes, he
seemed to have imprinted on the raccoon. He couldn't go anywhere without Groot
whining and mewling desperately until he caved in and started carrying the pot
with him, Groot's tiny tendrils wrapped around his neck. After Groot stepped
out of the pot, not much changed; he needed to be next to Rocket. Sleeping,
eating, showering, working, Groot had to be there. He had understood the
sapling's words from the very start, which had surprised him slightly. He had
expected the softness of Groot's larynx to mean he'd have to learn to hear it
all over again. Peter had said Groot sounded like a kitten, whatever a kitten
was. Rocket wasn't the only one The Colossus was affectionate with. He would
fall asleep in any of their laps, curled up into a ball, instantly making the
person smile quietly. But none got as much love as the raccoon.
There had been moments when Groot would be nestled against Rocket's chest, face
pressed into his furry cheek, letting out incomprehensible little mewls of
contentment while getting his narrow back gently stroked, and Rocket would feel
slightly paranoid and self-conscious at realizing he was being watched. But no
matter who had stopped to watch the scene, they would just smile very softly,
and keep walking. They were just so happy Groot was alive. The raccoon would
feel like an idiot at those moments, but the past was hard to shake off.
Rocket felt arms wrap around his waist, and was pulled onto Groot's lap. Now
that the young tree was larger than him, he did it all the time. Rocket loved
it. He scoffed indignantly, glancing up at the beaming, tender face.
"I'm trying to work here, ya damn houseplant," he said, causing his friend to
squeeze him with delight. Rocket snapped his goggles back on his eyes, leaning
over the device. The position was tricky but he didn't mind. He kept being
pulled back by Groot's hands. He groaned and straightened up, trying to glare
at the teenager and realizing the effect was probably hindered by his goggles.
"You're so kragging needy for attention," he huffed, impressed by how grumpy he
managed to sound. Groot smiled wider; there were no wrinkles around his eyes
yet. The Flora Colossus nuzzled the top of Rocket's head, making the raccoon
close his eyes and sigh in defeat.
"You're gross," he mumbled, leaning back, letting Groot plant little kisses on
his forehead and down his muzzle. Rocket grinned, trying to avoid Groot's
attempt to plant a kiss directly on his mouth. It had been cute when the
sapling was one foot tall, but now he was getting rather large, quite tall and
broad, and Rocket felt like it may not be completely appropriate anymore.
Groot's memory had not been restored yet entirely. He remembered most things
but there were still some aspects he didn't seem aware of, and Rocket had no
intention of rushing those memories on his mate. His tiny paw planted on
Groot's mouth, and he pushed his teammate away playfully. The Colossus let out
a low, coltish whine, and tightened his grip. Hoisting the smaller man up on
his lap, Groot tugged the goggles off. Rocket snorted.
"Go bug someone else will'ya?" he scolded, already pressing his eyes closed and
offering his throat for his mate to nuzzle. It was the part of his fur where
his scent was strongest. He wondered if it had something to do with why Groot
particularly enjoyed it, or if it was random. Groot's mouth pressed soft kisses
along the down of the raccoon's jawline, his neck, the underside of his muzzle.
Rocket could feel the trembling beginning deep inside him. The purr got louder,
and Rocket melted into his partner's lap, his fingers absentmindedly stroking
the firm arms holding him. Groot ran his mouth up the curve of Rocket's skull,
exhaling warmly against the round little ear before taking it gently between
his teeth. He had enjoyed nibbling Rocket's ears since he was a tiny sapling;
the raccoon was sure it was alright. The teenager's other hand stroked Rocket's
chest and shoulder in slow circles.
Then Groot said the word.
Rocket's eyes snapped open. It was the word he couldn't pronounce, the one
Flora Colossi used to signify their mates. Groot remembered. He knew how their
relationship used to be. Rocket's body tensed, froze completely. Suddenly the
arms around his waist, the hand caressing his chest, felt very strong. The hot
mouth nipping and tugging at the base of his ear gained whole new meaning.
Groot's low rumbling felt like Rocket hadn't even heard it before. He was being
romanced. A dry wheeze escaping his mouth, Rocket coughed, trying to swallow,
and pushed himself up quickly, only for Groot's arms to gently, very
determinately, pull him right back in. Rocket glanced at his mate quickly.
Groot's eyes twinkled.
"You, ah.. you remember?" Rocket croaked, disgusted at how weak his voice
sounded. Groot hummed with joviality, his thumb brushing against his mate's
nervous lips.
"When did you remember?" the raccoon asked.
"This morning," the Flora Colossus said.
"This morning!?" Rocket yelled. His mind raced back 10 hours, trying to
remember if he had done anything inappropriate. But what they were doing right
now was...
Rocket smiled too widely, his abdomen tensing involuntarily as Groot's fingers
brushed against the implant at the nape of his neck, and he tried to rise up
again, his tail already stiffening. Groot wasn't mature yet. He couldn't. It
wasn't right.
"I should probably..." he started, being cut off by his mate's mouth. Rocket's
eyes slid closed and he exhaled shakily, hands involuntarily wrapping around
Groot's crown. How he had missed this. The arms around his back pulled him in,
suddenly very strong, very broad. Or had they been that way? Had he not
noticed? His mouth opened and he gave in, and they kissed. And kissed, and
kissed. Groot tasted sweeter, the bitterness Rocket loved wasn't there yet. He
ran his fingers blindly over his mate's skin, reading the texture, the grooves
and ridges. It was so soft, so yielding. Rocket halted and opened his eyes. How
short Groot was. His skin raw and soft, green still, bark barely ghosting it.
The raccoon swallowed and pulled back, panting hard.
"We have to wait," he wheezed. He felt Groot's entire body thrumming softly
underneath his skin. It was a familiar sensation; he felt his spine arch
instinctively. The teenager's brows twisted, his gaze confused, searching his
mate's face.
"Why?"
"Because... you're not grown up yet!" Rocket said.
"I am, I remember everything," Groot assured. Rocket glanced around with
unease.
"I know, it's just, your body ain't fully mature yet, you know that, right?" he
asked, still working on evening his breath. The Colossus looked perplexed.
"Why is that relevant?" he asked. Rocket's brows shot up and his mouth gaped
open.
"It's illegal!" he snapped.
"We are not on a planet, we are on Peter's ship. There are no laws here. And we
have broken various laws 348,5 times," Groot stated. "Why do we have to change
now?" Rocket's eyes rolled around in panic, his mind scrambling for an answer.
"Because! Some laws are important and some are just shit! And this is one ya
don't break!" he said.
"Why?" Groot asked earnestly. The raccoon frowned at himself; surely, there had
to be an obvious, easy answer for this.
"Because..." he started, his voice trailing off. He had learned over the course
of years not to argue with the Flora Colossus on certain matters, especially
not issues of a philosophical nature. Ethics, morals, you name it; Groot ran
circles around him without the slightest effort, making Rocket feel as tiny and
stupid as possible. Groot was never mean or smug about it; his nature was open
and curious. It was Rocket's problem. Every new layer he peeled back, it dawned
on him more and more just how vast, how immense and complicated the man's mind
was. And he would try his hardest, tackle every angle, and Groot would take his
arguments, gently and innocently explain his view, and lay them on the ground.
And Rocket always felt like a complete idiot in the end. No, he had no chance
against Groot, but he felt so guilty he just had to try.
"You know why there are laws against it! And you know they're right!" he
muttered, glaring at his mate from under his brows. Groot pulled him closer,
flush against his chest, sending a shiver down the small man's spine.
"It is to protect minds that are not mature yet. My mind is mature. I remember
everything," he mumbled lovingly, brushing his mouth against a soft, twitching
ear.
"But it feels wrong..." Rocket whispered, already hard against the firm, warm
abdomen of his partner. Already, despite himself, grinding against it, his
fingers sunk into Groot's neck.
"Would it feel wrong if it were just us? Do you fear their reactions?" Groot
mumbled, dragging his teeth with sudden, surprising pressure up Rocket's
throat. The raccoon let out a downright embarrassing squeal, his hind toes
digging into Groot's thighs desperately. It was getting hard for him to form a
coherent thought. Maybe they could do this thinking business later... Rocket
crushed his mouth on Groot's, wrapping his legs around the teenager's waist.
The Colossus got up on his knees. Moans and gasps escaped Rocket's muffled
mouth as Groot's hands slid up his shirt, clawing at his back, squeezing his
ass. Rocket mewled into his lover's mouth; young Groot was more impatient,
rougher. He slid down an inch and inhaled sharply. He could feel it against his
thigh, hard and firm. Groot was out. Eyes dazed, Rocket looked down so fast he
nearly snapped his neck. It was thick and ribbed, a much lighter green, oozing
sap already. It smelled sweeter than before. Rocket let go and dropped on his
knees, staring at it at eye level. He grabbed it firmly at the base, feeling it
pulse beneath his fingers. Rocket admired it for a moment, and dove in.
It tasted sweeter, too.
Eyes closed in bliss, he ran his tongue on the underside lapping up the sap,
his mouth getting messy and sticky. He slowed down at each ridge, sucking
deliberately and making Groot let out a shaky groan. He looked up at Groot with
lidded eyes, his mate's young face contorted with pleasure, and closed his
eyes, taking the length deep into his mouth. The sound dragging out of the
Colossus made Rocket's erection twitch. It was usually Groot giving him
pleasure, selflessly and endlessly. He wanted to be the one giving now. He
licked the slick tip held between his fingers, rolling his tongue around it,
feeling the organ expand in his grasp.
"Rocket," Groot gasped desperately. The raccoon dragged his little fingers up
and down the ribbed length, feeling it twitch, and sucked the tip harder. He
was rewarded by quite a filthy sound escaping his partner. Looking up into
Groot's lovesick, hungry eyes, Rocket grinned. Groot knew that look. It was one
of those grins. The raccoon focused on the erection in front of him, took the
tip between his teeth, and gently, very gently pushed them down the length.
Groot shook all over, his eyes squeezing shut. He could never handle this. No
matter how many times it happened, he could never handle it. He just stopped
existing when those little teeth grazed him. He was all Rocket's, completely
helpless. He whispered the word, the one nobody but him could say, again and
again. Rocket added just a breath of pressure, digging his claws into Groot's
hips. The Colossus arched his back, his head tilting, wailing lowly. Rocket
wrapped his lips around the cock and sucked hard, fast, taking it deep into his
throat. Groot's entire body shook, and he came with a shuddering gasp, calling
his mate's name.
The sap oozed out of Rocket's mouth, overflowing, and he licked it up greedily,
panting and sweating. He had gotten so aroused by Groot he had erupted in his
pants, and the warmth was now spreading over the fabric. The raccoon sucked
Groot until he was soft, then got to work on his own fur with gusto. He loved
it, it was his favorite kind of grooming. Oh, how he had missed this. The young
Flora Colossus wrapped his quivering arms around a preoccupied Rocket, rubbing
his face fur with his forearms, huffing with joy. Groot pulled him very close,
nuzzling his cheek. Rocket was interrupted by Groot's mouth against his, and he
paused to kiss his mate. Groot laid down on the floor, and they kissed slowly
and tenderly, Rocket running his little paws over Groot's skin, clawing him
gently, nipping and gnawing at his jaw with a wordless smile. Groot caressed
his mate's back, making him purr again, scratching the raccoon behind his ears.
Rocket went back to grooming himself; he couldn't help it. The young tree
smiled and pulled his lover closer, watching the little paws work the dark
mask, the white fuzzy muzzle, the throat. Groot murmured sweet words into a
soft, round ear, eliciting an even throatier rumble from the raccoon.
