There's a surprising lack of Link/Saria and since I've always liked the pairing, I thought I'd give it a shot! Enjoy!

They exited the temple together. Having pulled the Master Sword from its pedestal and learning he was the Hero of Time, destined to defeat Ganondorf and restore peace to Hyrule, Link had decided to stop-in at his home in the Kokiri Forest first. His surprise at having grown over the seven years he had been in stasis in the Temple of Light had drawn him to familiar surroundings. However, upon his arrival, the energy emanating from the Forest Temple had corrupted his childhood home and he had bravely charged into the temple. One bout with Phantom Ganon later, Link managed to save his childhood friend Saria from the temple's depths. She had gone in herself to try and combat the effect on her home but been defeated by the various monsters within the temple.

The trouble now satisfactorily dealt with, the pair strode out of the Forest Temple together and down into the Sacred Forest Meadow.
"I don't like that you're taller than me now." Saria teased, looking up at Link. His seven years in the Temple of Light had blessed him with a significant growth spurt, she now only came up to his chest.
"It's been weird for me too. I could see the top of my wardrobe. Turns out it gets really dusty up there after seven years." Link smiled down at her and she giggled "You haven't changed a bit though."
"Thank you Mr Hero!" she beamed up at him.
"You don't have to call me that." he blushed "We're friends remember?"
"Best friends!" Saria grabbed Link's hand "So now that you're all grown up, what else is different? I want to hear about everything!"
"Not much." he confessed "My hair is a little longer and my ears are a little pointier but I'm mostly the same, just generally bigger." he shrugged
"Generally bigger?" she asked "Like…everywhere?"
Link's blush deepened "Sure."
Saria's mind began to wander. Back when Link still lived in the forest, they had found a book in the Lost Woods no doubt dropped by someone trying to escape. It turned out to be very educational and taught both Link and Saria a lot about their bodies and how they could be used to pleasure each other. They spent several weeks secreted away, trawling through the book and occasionally experimenting on each other. Their inexperienced fumbling didn't get them very far and it turned out Saria was more interested than Link, often having to promise him favours and to do his chores in order to get him to even look at the book. She had hung onto the book all this time and had spent many a night by herself, flicking through the pages (especially the ones towards the end) absorbing all the information. She'd found herself getting aroused by the pictures and diagrams, often imagining herself in those situations with a tall, dark, well hung stranger. And here she was alone with someone who was definitely tall.
"Can I see?" she jumped in front of him, beaming.
"Can you see what?" he stopped in his tracks, looking quizzically at his best friend.
"How big you've got." she said matter of factly.
"But you can see how tall I am." Link said bemusedly
"What about down there though?" Saria gripped the hem of his green tunic, lifting it slightly.
"Saria!"
"What? I'm just curious." she smirked and sank down onto her knees "And you're not stopping me."
"But here? And you're…I'm…but you-"
"Relax you big baby." Saria winked, "I just want a peek." she reached under his tunic, her hands running up his thighs until she found the waistband of his leggings. In one swift movement, she pulled them down to his knees and tucked his tunic into his belt. Saria's eyes drifted to Link's semi-hard cock now freed from its confinement.
"You were right, you are generally bigger!" Saria giggled, reaching out to cup Link's balls. They sat heavy in her hand and he shuddered at her touch, slowly rising to full stiffness. Saria stared in awe, it looked exactly like the diagram in the book now. Her thoughts soon drifted to some of the later diagrams.
"Can I touch it?" she asked
"I-I mean-" Link stammered "If you want?"
Saria's hand drifted upwards and she wrapped her small hand around his shaft. She couldn't fit her entire hand around it and an intense heat radiated from it. Saria was transfixed, it pulsed in her hand in time with Link's heartbeat. He stood looking down at her as she gazed at his cock in wonder, feeling a little self conscious.

Saria began to move her hand, slowly stroking along his length, totally transfixed by what he had been hiding until now, it was easily as big as her forearm. She caressed it lovingly eliciting soft moans from Link who was still apprehensive but unable to stop her from continuing. Thinking back to the diagrams in her book, Saria tucked a strand of hair behind her ear and leaned closer. The musky scent filled her nostrils making her head spin and she tentatively drew her tongue across the tip. Link gasped at the sensation and Saria had the salty teste of his precum in her mouth. She swirled it around for a bit before swallowing.
"You taste good Link!" she smirked at him before engulfing the head of his cock in her mouth.
Link's hands immediately flew to her head, gripping it gently as she swirled her tongue around his cock, exploring everything she could and lapping up the precum now leaking from his tip. Saria started to bob her head slightly, taking in a little more of Link's cock at a time, her tongue running along the underside coaxing it further. Link's fingers tangled in her hair, gripping her pointed ears and forcing more of his cock into her mouth. Saria felt it begin to tickle the back of her throat and gagged, pushing away from him.
"Woah! Do you know how big you are compared to my mouth?!" she panted looking up at him. Her saliva coated maybe a quarter of his length.
"Sorry, it just felt really good." Link said meekly. Saria wiped her mouth with the back of her hand.
"You're lucky you're so charming." she kissed his tip and stood up, crossing to a nearby tree stump "Don't worry, I have somewhere else you can try though." she bent over, placing her hands on the stump and pushing out her ass and wiggling her hips seductively. Link looked hesitantly at the display.
"Come on Link!" she huffed "I'm asking you to fuck me ok? I've wanted this for ages and now that monster cock of yours has got me really turned on!"
Sure enough a sizable wet patch had begun to form on her shorts. Something seemed to shift in Link at this sight and he quickly closed the gap between them, discarding his boots and leggings as he came.
"You like it when I shake my ass for you?" Saria teased "Or maybe you just like seeing how horny you make me?".

Suddenly, Link grabbed her shorts and pulled. They tore free from her body and he tossed the remaining fabric aside. Saria gasped, her plump ass exposed to the air. A small part of her brain told her something wasn't quite right but it was quickly silenced as she felt his hands on her. Saria wiggled her hips seductively, bracing herself against the tree stump.
"Come on then Mr Hero, take your prize."
Link spread her cheeks apart, revealing both her holes. Saria's pussy was soaked, glistening with her arousal, her plump lips parted slightly quivering with anticipation. Link took in the sight and his eyes strayed upwards to her puckered asshole to which Saria, her head craned back over one shoulder taking in Link's look of hunger, said:
"Surely the Hero of Time deserves both?" This caught Link's attention and he raised his eyes to meet hers. Inwardly, he couldn't believe that his best friend, the girl who had been on so many adventures with him in this very forest, was presenting herself to him like this, his cock twitched in anticipation, her saliva still glinting in the sunlight.

"Well?" she cocked her head to one side and winked at him and he made up his mind.
Link positioned himself and pressed the head of his cock against her dripping folds. Saria gasped and moaned as he began to slip inside her, Saria's petite frame resisted the intrusion and her fingers dug into the wood beneath her as she felt Link's cock stretch out her tiny pussy, forcing it to accept his rock-hard member. She screwed up her face, panting with exertion as the head of his cock slipped inside her.
"Saria…" Link moaned "Fuck you're tight."
"I want it all Link!" she cried out and he continued to slide slowly into her. She could feel her abdomen bulging as her tiny body stretched to accommodate his girth.

Saria let out a guttural moan as she felt his cock press against her cervix and knew this was as far as Link could go. She felt her pussy spasm around him and Link moaned as he realised he'd managed to squeeze only half of his length inside her.
Saria's arms went limp and her pointed ears twitched as she felt a rush of pleasure course through her. Link was inside her, stretching her to her limit and she needed more.
"Please Link," she pleaded, craning her head as much as possible to catch what little glimpse of him that she could "Fuck me!"

Link nodded and began to pull back, allowing her insides to contract before plunging back into her, the tip of his cock kissing her cervix with every thrust. Saria moaned every time Link thrust into her, reveling in the sensation of being filled and stretched around her best friend. Link grabbed her hips, pulling her back into him and matching his thrusts. Saria's moans became gasps as she was pulled and pushed across the stump beneath her. She snaked one of her hands down her body until it came to rest on her abdomen and the prominent bulge that was Link's cock protruding from her normally toned abs. Marveling at the feeling of Link speeding up his thrusts and the feeling of her stomach stretching around his girth, she reached down further and began to rub circles around her clit. It felt like her insides were on fire and her clit throbbed with desire, she'd explored her own body before and made herself cum in those dark winter nights in the Kokiri Forest but nothing she had experimented with came close to this feeling.

Link was in heaven. Saria's pussy had him in a vice-like grip and her grunts and moans did nothing but encourage him. Her petite frame quivered with every movement, his hands sunk into the supple flesh of her waist as he gripped her, forcefully pulling her tiny body back onto his throbbing cock. Saria's pussy gushed around his length, coating all that it could and dripping onto the tree stump below, he felt her begin to tense up and slid his hands up her body until they cupped both of her petite breasts, massaging them through her green top. He felt her nipples stiffen, poking through the fabric as her breathing became shallower.
"Link…" Saria groaned "Hylia! I'm so close! Fuck! Don't stop!"
Releasing her tits, Link grabbed a fistful of her lime coloured hair and pulled, she was raised away from the stump supporting herself weakly as Link began to thrust up into her.

Saria's mouth hung open, panting and short gasps filled the air as her mind began to go blank. All she could concentrate on was the feeling of Link pounding her pussy. The way he stretched her to her absolute limit was exhilarating, a jolt of pleasure spiking through her every time he thudded against her cervix, the tightening of her walls around him squeezing his immense girth, his fingers in her tousled hair pulling painfully but being drowned out by the all-encompassing pleasure that was filling her entire body. A tightening in her core, a building sensation in her extremities foreshadowed the release that was soon to follow. With a sudden burst of stamina, Link increased his pace yet again and the spell broke.

Saria's screams echoed through the forest. Her legs shook, her arms went limp and her pussy gripped Link as tight as it could, gushing her juices all over his groin. Saria's eyes rolled back into her head as wave after wave of intense pleasure crashed into her, being unable to support herself any more she was being held up by Link's fist in her hair. Tongue lolling, she fought for breath as she felt Link retreat from her. He flipped her over, her back now pressed against the stump and resumed his assault on her womb. All limbs flopping limply, she lay spread eagle as Link had his way with her.

Link could feel the tension building inside himself and with Saria spread out beneath him, he knew it would not be long now. He stared at the outline of his cock protruding from Saria's abdomen as he plunged into her, watching the petite girl's body extend to accommodate his length. Gazing back up at her face, he saw Saria's lips forming words, unable to speak. She held his gaze, her slightly unfocused look and messy hair turning him on further as she finally found breath enough to speak.
"Link. Link. Link." weakly at first she muttered his name, then faster, punctuated by moans. He timed his thrusts to her cries, sheathing himself inside her only when she cried out his name.

"Saria!" he groaned
"C-c-um!" she panted "Inside me! Please!"
"You sure?" it was all he could do to hold back after that last pleading statement.
"Please!" she screamed "Fill me with your hot cum Link!"
And that was all he needed. With one last thrust, he buried himself inside her, the head of his cock pressed firmly against her cervix and came. A spasm of pleasure coursed through him with every spurt of cum he shot into her womb. Saria orgasmed again at the sensation, her walls tightening around him trying to coax yet more cum from him. They both moaned each other's names, basking in the other's orgasm. With every throb of Link's cock, more cum flowed into Saria until finally he pulled out.

He stood over her, panting with his cock resting on her abdomen where moments before it had strained against the confines of her insides, it twitched on her stomach, their combined juices shimmering in the sunlight. Saria's pussy quivered occasionally, still yet to return to its previous size, gaping slightly with a slow trickle of cum flowing onto the forest floor. She lay beneath him limply as feeling returned to her, a dull ache filling her entire body.

Link continued to gaze down at her petite frame, limp from exhaustion. Saria's tousled hair had fallen into her face a little and been slicked down messily with sweat. Her small nipples strained against the fabric of her top, her small breasts still rising and falling with every deep breath. He was transfixed by her small, exhausted, sweat covered body and his arousal persisted. His cock rested against her stomach, still as hard as it had been minutes before, even as his last load dripped slowly from her.

Saria felt a painful throbbing sensation through her pelvis as feeling returned to her, her pussy was left gaping after Link's girth and she could finally feel the pain that had been dulled by the pleasure. She smiled weakly up at him.
"That was…amazing…" Saria closed her eyes and drifted off.

Some time later, she found herself awake in her own bed. She sat up gingerly, a spasm of pain shooting through her body. She groaned and ran her fingers through her hair.
"Good morning sleepyhead." Saria whipped around to see Link hunched over on a chair next to her bed that was now far too small for him. She gave a weak laugh at the sight and Link joined in.
"How are you feeling?" he asked
"Very sore." she confessed "But also, satisfied. You really know how to fill a girl."
"You started it. You just feel really nice and you make cute…noises." he trailed off, embarrassed. Tt was Saria's turn to blush, even through the aches and pains she felt warm and fuzzy inside "You're really good at…everything." she mumbled, Link laughed again.
"Thanks, you're not so bad yourself."
"Could we…do it again some time?" Saria asked, not looking at him and bunching the sheets in her hands.
"Of course, but only when you're not as sore. Deal?"
"Deal!" Saria beamed at him. Link leaned over and pressed his lips to hers, taking her by surprise. She felt that next time couldn't come soon enough.
