Fun With Fanciful Fungi

Author's note: Everyone in this story is obviously 18+ and you should not be reading it if you are under 18. This story is basically all about the expansion kink which involves body parts rapidly growing in size in a way people who enjoy the kink find sexy. If that doesn't sound like your thing you don't need to be here. I normally write in a relatively limited third person perspective but for this story I tried to be a little more fluid with the perspective. I also tried to play with the idea of expansion being accompanied by distracting enough thoughts to delay noticing what was going on. Comments and feedback are very welcome, but especially on those last two points.

Synopsis: A flirty bet leads two assistant alchemists to not use proper precautions when harvesting puffshrooms. Expansion and sex ensue.

"Oh that one's mine!" Lizbeth cheered as she spotted one of the bright purple mushrooms amidst the verdant green underbrush on the side of the wide path. The slender elf darted towards it, before her human companion could even try to make a move for it. Their mistress had urged them to be cautious of the mushroom's spores as they harvested them, though she had not elaborated on why. Perhaps if she had explained just how embarrassing the puffshrooms' effects were, Lizbeth would have been a bit more circumspect as she grabbed the thing and waved it about triumphantly. In the shade of the forest, she didn't even notice the fine cloud of purple spores drifting over her as she turned to taunt her companion.

The elven woman smirked gleefully at her quiet human rival, as she tucked a stray strand of her short blonde hair behind her pointed ear. "Take that Prince, I'm going to have my basket filled way before you!"

The prince in question was not an actual prince, though Morton had long since given up on explaining that to the blonde elf. He was the third son of a minor noble, which basically meant he had a bit of money and his choice of occupation but no real power. For that choice of occupation, he had decided he wanted to become an alchemist, to his parents' surprise. Further shocking them, he seemed to have some talent for it, having finished his apprenticeship with distinction and a year early at the age of twenty-three. From there he had been offered the opportunity to serve as an assistant to a master alchemist. If he had known in advance what that master's senior assistant was like he might have chosen a different career path.

Lizbeth was tall, leanly athletic, and confident, none of which was particularly surprising for an elf. It was her boisterous competitive nature that caused Morton such grief. No sooner had he started in his position as second assistant than the only marginally more senior elf had declared him her rival. The shy, reserved noble's son had certainly not been prepared for the constant challenges and teasing. Especially given that Morton found Lizbeth, with her sharp chin and long elegant nose, to be pretty enough that he would have been at a loss for words with her even had she been gentler with him.

Today as ever Morton found himself trying to keep a level expression in the face of the elven woman's provocation. It helped that his short brown beard and his thick eyebrows gave him a perennially pensive look. Though in this particular case, all he was thinking about was how he might impress the elf if he could actually best her today. "It's not about the quantity of puffshrooms, it's about the quality," he returned with as much confidence as he could. Hoping to prove his point, he scanned the thick underbrush for the telltale bright purple of puffshrooms.

It took only a few moments to spot a large one hidden beneath a fern which he collected before the elven woman could beat him to it. Though normally more prone to caution than Lizbeth, Morton's desire to impress her had him forgetting his mistress's warnings about the spores of the mushroom. As he held out the puffshroom for the elf's approval he didn't notice the cloud of purple spores he breathed in either.

Lizbeth let out a huff seeing that Morton had indeed found a larger puffshroom than she had, though she was far from disappointed to see him trying to best her. If anything, she was even more excited than usual at the prospect of competing with the handsome human, her skin feeling pleasantly tingly at the thought of demonstrating her superiority to him. She felt a thrill run down her spine as she imagined defeating him once again and perhaps finally breaking through that aloof façade he wore.

"It's not bad," she murmured getting another whiff of the spores as she inspected his puffshroom. "But while you were so busy picking that one I found two more." She produced another two mushrooms that she had quickly plucked while Morton had been distracted. With a flourish she waved them about victoriously, their purple dust drifting into the air between the two alchemists.

Morton's eyebrows shot up at the revelation that she had found even more of the puffshrooms so quickly, his momentary pride at having found the better specimen absolutely eviscerated. "I'm sure I could find more too I weren't looking for the best ones for Mistress Alana..." His face and in fact his whole body felt very warm, a reaction he assured himself was purely due to surprise at the elf's speed in mushroom picking.

The look of surprise on his face, those dark expressive eyebrows of his shooting up, was absolutely delightful to Lisbeth. That tingling sensation she had been feeling began to creep downwards, the beginnings of a very particular kind of tension in the elf. Feeling even more daring, she decided to raise the stakes. "Perhaps we could make a bet. We'll ask Mistress Alana who did a better job of collecting puffshrooms. The loser has to do whatever the winner wants for a day...No a week!"

Morton gulped in the face of his elven companion's confident grin. Despite the forest's plentiful shade, he felt so hot it was hard to think straight. Especially with the blonde looking at him like that...smug, eager but also...hungry. The calm rational part of him knew it was stupid to encourage Lizbeth's goading but that part of him was uncharacteristically silent in his thoughts. Instead, his desperation for his beautiful companion's approval was rising to the fore...along with other more embarrassing feelings. Fighting those thoughts down as best he could he gave a resolute nod. "Fine I accept your terms."

Lisbeth absolutely cackled in delight as he nodded. "Oh Prince, you're going to make such a wonderful servant!" Her voice was perhaps a little more sultry than she meant it to be, and she could feel herself warm as she saw a blush creep onto Morton's features. She couldn't help it though, the thought of the noble having to wait on her hand and foot was creating a very pleasant pressure between her thighs. "You take that side of the path and I'll take this one?" She cocked an elegant eyebrow at him. Seeing another nod from him she turned on her heel and sauntered off to the other side of the path in search of more mushrooms.

As the elf turned, Morton breathed a sigh of relief. Whatever tension the young man usually felt when dealing with the elf was somehow even more intense today, and Morton was having a hard time handling it. Even that quick exchange had left him feeling flustered and oddly (though not unpleasantly tingly). Those tingles had seemed to settle down in his groin and he was quite embarrassed by the feeling of his trousers pulling tighter as his bulge grew. And all she had done was give him a look. At least she seemed too distracted in her quest for puffshrooms to notice.

Though he knew he should focus on his own search for the mushrooms, he couldn't help but let his eyes be drawn to Lizbeth. Due no doubt to the warmth of the day, the elf had worn a thigh length flowy skirt that seemed to bounce every which way as her hips swayed. The outfit displayed plenty of her long, toned legs for Morton to gawk at, his mind absently wondering what it might be like to trail his fingers over her smooth skin. Those thoughts did nothing to help ease the growing situation in his trousers.

Things only got worse when Lizbeth let out a trill of triumph and bent to pluck a puffshroom from the ground, the action pulling the fabric of her skirt tight across her ass. Morton could feel his cock throb heavily at the sight, pushing against the inside of his trousers as he thickened. He managed to tear his eyes away from her ass when she straightened to look at him, his hands reflexively positioning his mushroom basket to awkwardly hide the lewd bulge in his trousers. "Two more." She waved the puffshrooms about for him to see.

Embarrassed both at how quickly she was pulling ahead and the fact that he had almost been caught staring at her ass, Morton cast his eyes about for any puffshrooms on his side of the path. It took only a moment to spot one of the bulbous purple fungi growing in the roots of a tree. "Well I see another big one!" he called as he bent to pluck it, his haste making him quite heedless of the cloud of purple spores he inhaled.

Lizbeth grinned to herself as she returned to her own quest for puffshrooms. She hadn't missed the color in his cheeks as she had taunted him a few moments ago, nor had she failed to note the way he held his mushroom basket in front of his crotch. As he had turned towards the puffshroom he had spotted she had even gotten a quick glimpse of what he had been hiding. It was of course hard to be sure with him standing so far from her and still wearing his trousers, but Lizbeth was quite impressed by what she had seen. She wasn't sure what it was about today, but she was glad to be finally getting that kind of reaction out of the noble.

Of course, the elf wasn't exactly having the easiest time maintaining her composure either. Contrary to her expectations, the shaded forest seemed even warmer than the fields they had crossed to get there, and she found herself starting to sweat. Her perspiration combined with the hiking was having the effect of making her clothes feel quite uncomfortable, her normally loose blouse clinging to her breasts, while the fabric of her skirt kept rubbing across her ass oddly. But the biggest problem lay beneath her skirt. Her underwear felt quite damp, which was surely just sweat and not her tingly pussy beginning to drip at the thought of the noble waiting on her hand and foot. Regardless the source she was certainly going to have to do laundry when she got back.

She began to search for the puffshrooms somewhat absently as her thoughts of laundry started to mingle with the idea of making the human serve her. When she won would she ask him to do her laundry for her, her sweaty clothes from the day sitting on top of the pile? How might he react when he found her grooly underwear? Would that be enough to get him to stroke that fat cock he was hiding? The thought sent a shiver down her spine as she bent to pick up another puffshroom. She attributed the renewed surge of warmth she felt to her increasingly lusty fantasies about her fellow apprentice and not the mouthful of spores she breathed in.

As that warmth spread sensually through her body, causing the sensitive skin of her breasts, ass and thighs to flush, Lizbeth quickly glanced at Morton where he had taken a knee to examine a puffshroom. Though she was too far to see the faint purple cloud of spores that settled over him as he picked it up, with his body turned to the side she could clearly see the profile of his bulging cock. Her mouth practically watered at the sight and through the warm haze of her fantasies she knew she absolutely had to get a closer look at it. With the puffshroom spores clouding her thoughts, it never occurred to her that Morton's package hadn't looked quite so large before. She simply assumed he was an absolutely magnificent grower.

"My that's a big one!" she purred as she rose to her feet, not noting the way her breasts tried to bounce against her increasingly snug blouse. "Perhaps we should compare baskets to see who is doing better?"

For his part, Morton had been entirely lost in his own hazy thoughts, every movement he was making causing his heavy cock to rub delightfully against his trousers. The experience was so thoroughly distracting that Lizbeth's voice startled him, causing him to fumble the large puffshroom he had been holding, a fine cloud of spores issuing forth to coat him. In the moment it took him to register her suggestion, she was already advancing towards him, hips swinging suggestively.

Quickly he retrieved his dropped puffshroom and stood to his feet, using the hand holding the basket to try to adjust his pants so that his cock ran down his leg rather than point directly at the elf. Turning his attention back to Lizbeth, he couldn't help but note the hungry look in her hazel eyes or the flush across her cheeks. He could feel himself blushing even more in response, his gaze following a single bead of sweat as it ran down her neck into the pale, creamy cleavage her blouse exposed.

In his mind Lizbeth had always been slight as one typically assumed of elves, but he clearly hadn't been paying enough attention because there was nothing slight about the elf's breasts as they practically threatened to spill out of her low-cut blouse. He could tell he was staring, but with his cock throbbing and starting to leak precum into his pants he really didn't have the wherewithal to do anything else. After a few nervous swallows he finally managed to speak. "I-I've only been picking the best ones." Though he still couldn't quite tear his eyes away from the gentle rise and fall of her breasts, he did manage to lift his basket for her to inspect.

"I'll be the judge of that," Lizbeth snickered confidently, though the proximity to the human and his massive cock had her heart racing. Her full lips turned to a smirk as she saw that his gaze was glued to her chest, wondering if he could see her hard nipples through the fabric of her blouse. She hadn't bothered to wear a bra, which was perhaps a mistake as her chest felt like it might need a little more support, but it was more than worth it if it got Morton's attention firmly on her.

The elf's gaze was similarly wandering. Though she made a show of inspecting the puffshrooms in his basket, her eyes kept drifting to the extremely obvious outline of Morton's cock running almost half the length of his thigh. She could feel herself practically drooling as her mind flooded with images of mounting it. But she wanted him even more pent up for her first.

Teasingly she wiped a bead of sweat off her chest, before moving her hand to touch the puffshrooms in the basket, hoping to snare the human's attention. Then she slowly ran a finger along the length of the largest puffshroom's stalk. "Oh goodness this one is so big. Mhmmm and thick," she purred, trying to keep her tone just neutral enough for plausible deniability. Her eyes darted down to the bulge along his thigh and she was delighted to see it actually throb against his trousers, a wet stain forming at the tip. She was far too preoccupied with her teasing to notice the cloud of spores she was stirring up, her thoughts growing increasingly foggy and lustful.

After several long moments of her lewdly fondling his basket of puffshrooms Morton finally managed to muster enough willpower to pull the basket away. "N-nice try but I'm not going to let you ruin my choice puffshrooms." He hoped the challenging words might distract from his obviously flustered appearance, which only got worse as a new wave of heat washed over him, flowing straight to his pulsing cock.

Lizbeth scoffed at the suggestion that she might be trying to ruin his puffshrooms, but she was having a very hard time keeping a cool expression. She wanted Morton so badly and judging by the way his cock was still throbbing in her peripheral vision he wanted her as well. It would be so easy to pull the scholarly man to the ground and have her way with him...but the raging tingly heat running through her body hadn't reached the point that she was willing to abandon her competitive spirit and throw herself at him. Even more than she wanted his thick cock to fill her aching pussy she wanted it to be because she had won and he had begged her for release. Which just meant even more teasing was in order.

Feeling suddenly rather devious she did a quick scan of the ground around them for more puffshrooms, her plump lips forming a thin smile as she spotted one. "I don't need sabotage to win. After all I just found yet another puffshroom." She turned away from Morton, bending at the waist exaggeratedly to pluck it. The pose should have afforded him a rather wonderful view of her firm ass, but her upper body felt a bit heavier than she expected and she soon found herself overbalanced and stumbling forward. To keep from faceplanting she had to drop her basket, the impact sending a cloud of spores right into her face.

Embarrassed, the elven woman felt another surge of warm tingles making her pussy gush and her knees weak. She found herself stumbling backwards a bit, towards Morton. Despite herself Lizbeth couldn't help but gasp as she felt her soft butt squish against his crotch. Her skirt must have ridden up a bit because she felt far more of the rough fabric of his trousers rubbing against the sensitive skin of her thighs than she would have expected. But she only had so much room for thoughts about the state of her skirt when she could feel the hard bulge of the human's cock pressed against her.

Morton had been far too distracted staring at Lizbeth's bubbly ass as she bent to pluck the puffshroom to have the wherewithal to help her when she started to stumble. He was completely unprepared for her to reverse course right into him and could only grunt in surprise when he felt the jiggly flesh of her butt press up against him. To save his balance he dropped his basket of puffshrooms, spores drifting everywhere, and caught the elven woman's wide hips. Distantly he was surprised that Lizbeth had managed to hide such bountiful curves beneath her skirts, but he had no time to dwell on that thought as he began to feel the heat radiating from the woman's lower body washing over his crotch.

That heat flowed into him, pulsing throughout his body before pooling in his cock and balls which he could feel growing heavier with lust. He would have sworn he was already as hard as he could possibly get, but he could feel himself throbbing longer and thicker with each passing moment he was pressed against the soft warmth of Lizbeth's backside. The damp feeling in his trousers was rapidly getting worse, his sweat from the heat mingling with the precum that wouldn't stop leaking from his twitchy cock.

The only sound in the woods was their heavy breathing as they stood there, her bent over and him pressed against her ass. It took several moments before Morton realized that his hips were pushing against her, and with an effort of will he pulled them back. "Uh s-sorry...I mean are you um okay?" he asked, embarrassment and lust conspiring to turn his entire face crimson.

Lizbeth wasn't entirely sure she trusted her legs to stand. The feeling of the thick length of Morton's cock pressing up against her backside had flooded the elf's pussy, leaving her a sweaty weak-kneed mess. When the human had pulled his hips back, it took all of her willpower not to push her ass back into him. But after a false start or two, she managed to retrieve her basket and slowly stand. "I-I'm fine. I just tripped that's all." She hoped Morton didn't notice just how shaky her voice was.
