"And you're sure this would all be safe?" Jay asked, sitting on the black leather couch of the apartment him and his partner Tina shared.

"I've been promised it's safer than taking a plane let alone that hour-long commute of yours" Tina boldly declared with no real evidence in an attempt to comfort her boyfriend on the safety of the app she'd been excitedly explaining to him for the past hour.

Tina, the 23 year old freshly graduated design student, was more than excited about the new app her friend had showed her last week.  To be more specific, the extremely experimental unreleased app her friend Sam had given her after plenty of begging and only with the promise that she'd treat it like a real beta test and report everything.

Tina had her ideas as to where the app came from, Sam's nerdy, recently hired my a mysterious tech company boyfriend sprang to mind.  But Tina didn't care about that part in the least, she was far more interested in using this app to sate her own curiosity, among other desires, with her boyfriend.

Jay himself was as curious as anyone would be when approached by their partner with an app that can seemingly break the laws of physics and modify human sizes.  The things Tina was talking about doing on the other hand had him hiding a hard on while he pondered the safety of it all.

"I mean if my darling girlfriend wants to do this, who am I to disappoint her" He said with his doubts seemingly assuaged.

"Yay! thank you so much sweetie, I promise you'll love this just as much as I will!" She  bounced up and down like a kid finally about to open a Christmas present they waited all night for.

"So how do we start?" Jay asked as he got up from the couch to see what Tina was fiddling with on her phone.

"The app pairs with anyone within a certain radius so we can start right away!" as she said this Tina handed the phone to Jay and pointed to a few settings.

"This slider will change my size up to the limit I set so feel free to make me as small as it lets you" she said with a wink as she slowly leaned into her boyfriend with her lips by his ear.

"And I can't wait to see how big you get" She whispered into his ear seductively as she began to slowly rub her boyfriend's crotch.

With that encouragement any resistance to the idea Jay may have had left vanished, just as quickly so did 6 inches of Tina's height as he gave into her charms.

For Tina the change was instant and jarring as her already petite 5'6" frame dwindled down to 5' flat, From Tina's perspective her already 6' boyfriend seemingly gained 6 inches of height in the time it took her to blink.

This change was both terrifying and exhilarating at the same time as Tina went from barely looking up to meet her boyfriend's vision to needing to crane her neck to do so, this simple change made her far more excited than she thought she could get as she began to undo Jay's belt.

"Let's see how this guy looks at this size" She giggled to herself as the pants came down and out came Jay's erect 5 and a half inch cock. "Someone's happy to see me shrink isn't he" before he had a chance to respond she had already started to suck his dick with an even tighter set of lips than he was used to.

"Think I can still take this whole thing at this size?" she asked, more as a challenge to herself than anything as the only response she got from Jay was moans of pleasure as she kept going.

On the next pump she took his whole cock in his mouth and struggled greatly with the last inch as she took it into her throat just barely succeeding with the task she set out for herself.

"How about we take this to the bedroom?" Jay barely got out through his moans, "I thought you'd never ask" Tina responded with a devilish smile that boiled with lust.

The two darted towards the bedroom all the while doffing what clothes they had left, a particularly easy task for Tina who was already wearing seemingly oversized clothes.

As the two landed on the bed together Tina rolled on top of Jay and hovered her now bare pussy over his awaiting member, with his hands landing naturally on her hips Jay pulled Tina onto his eager cock.

Shock filled her body as Tina took in this dick, seemingly at a much larger size than she was used to, the pleasure from the insertion set her senses on fire as she craved more.

She began furiously riding up and down Jay's thick member, the pleasure of which blinded her to her partner's subtle use of his phone as she was suddenly shrunk once more, another six inches placing her at 4'6".

The pleasure was out of this world for Jay as the pussy he had been fucking so often recently got incredibly tight to the point he may finish in just a few pumps at this rate.

For Tina this change in size felt like more than she could handle as the cock inside of her grew proportionally larger and now bulged just under stomach with every pump, the pain of taking in such a massive object melted with the pleasure as she continued her efforts albeit while occasionally taking in a little less than the whole member.

Noticing this Jay grabbed his now beyond petite girlfriend by the abdomen and pushed his way deep inside her as she wailed in what he hoped was mostly pleasure, this seemed to completely stun Tina as her eyes glazed over from the action.

Leaning up towards her ear he asked her "Do you want to get smaller for me baby?".

The pleasure had nearly made her pass out but hearing that jolted her awake as Tina couldn't help but imagine the feeling that would follow her shrinking, she gave a timid nod, not completely sure whether she should but indulging all the same.

With that she shrunk again, this time only losing another 3 inches to both her joy and dismay as some part of her wanted to be even smaller while the rest of her mind was busy dealing with the feeling of growth inside her as the already massive cock grew once more for her.

The increased tightening made Jay understand neither he nor Tina would last long at this rate.

Rolling over Tina was now underneath Jay, her seemingly almost 8 foot tall boyfriend, she pondered to herself the specifics of their size for mere moments before the giant before her drove his massive cock into her now barely large enough to contain it pussy.

The pain alone felt like it could knock her out but the overwhelming desire for the pleasure she was feeling right now completely removed any other feelings from her mind, as Jay started his final series of pumps Tina knew what was coming.

Both of them began to moan furiously as all the two could feel or think about was the pleasure they were feeling right now, Jay realizing his estimations from before were useless now began to thrust as fast and deep as he could knowing he wouldn't last another minute like this.

Being on the receiving end of this final series of thrusts made Tina's mind go blank with pleasure as she came furiously from the greatest pleasure she'd ever imagined.

Feeling the spasm of her orgasm Jay finally pulled out and came just as she did, a massive torrent of cum flooding from his cock, underneath him Tina recovered from her orgasm just long enough to see her looming lover deliver far more cum than she thought possible all over her stomach completely soaking her in his juices.

"Fuck me that was more than I expected" the giant known as her boyfriend exclaimed, quickly rushing off to get her a towel to clean up and bathe in the afterglow of that perfect orgasm.

Tina cherished the feeling of being coated for a few minutes before wiping herself off and nuzzling into her massive boyfriend's chest.

"We definitely need to do that again" Tina said with more than a hint of enthusiasm "after the soreness goes away that is" as she began to feel the after effects of what they'd just done.

Worth it she thought to herself before her thoughts were interrupted by a question from Jay "How small could I have made you by the way?" he asked curious as to how far she would have gone.

At this point she'd completely forgotten about the app after everything that happened, "I don't remember what I set as the minimum actually" she realized in the moment, "are you getting curious about this stuff now?" Tina asked, flashing a haughty smile impressed that she'd converted her boyfriend so easily.

"Well I was just thinking it would be a waste not to try it out, you said we were testing it after all"

"In that case take me away darling, I'm curious to know just how small I'll get" although a bit nervous she did want to push things as much as she could.

As he swiped his finger across his phone moving the slider as far left as it could go Jay watched Tina dwindle from her previous height of roughly 4 feet tall down to 3 feet as she crawled further onto his chest, barely even feeling a difference in weight he continued to hold his finger as she continued to shrink.

Tina was in awe watching her boyfriend go from something that resembled a large human to more of a bed sized object, she was amazed at the scale of it all until she realized she was still shrinking.

How far did I set this she began to ponder to herself, she began to worry when she would stop, soon she was no longer laying on Jay's chest but standing in order to be eye level with him.

But it just kept going.

Soon she was staring upwards at the face several times the size of her own body, she couldn't have been more than three inches tall, suddenly the world grew even faster as she realized the shrinking would make her perceive the world as exponentially larger as she got smaller and smaller.

She eventually stopped shrinking at what she estimated to be half an inch, Jay's chest had become a massive field made of alien material, his lower body seemingly spanning miles into the distance, all the while Jay himself seemed to have grown into a distant god peering down on her.

"Wow you're into weirder stuff than I thought babe" The titan began to speak, from Jay's perspective it was barely average volume but to Tina it was a shock wave she could barely understand as she held her own ears to lower the ridiculous volume she was faced with that suddenly erupted from the god's mouth.

In that moment Tina realized her own insignificance, she trembled in fear of course, but also in overwhelming pleasure as she stared up at the man who had nearly deafened her with a few quiet words.

I'm going to really enjoy this app, she thought to herself as she gazed in awe at Jay and the overwhelming landscape he had become while slowly began to bring her hand lower to a part of her body that was already eager for more, realizing they had just scratched the surface.

Tina was sitting on the couch on a nice snowy day, cozy as could be in Jay’s hoodie and cotton pj shorts when suddenly she hears the familiar sound of keys in the door.

Jay threw open the apartment door, “Oh my god do not go out there it’s freezing”.

“Welcome homeeee” Tina shouted as she rushed in for a hug before suddenly stopping.

“You’re soaking wet baby, get out of those clothes so I can hug you to warm you up already”.

Jay started to remove his coat and walked over to the bedroom to change “Sorry to say T but you may be a lil too small to warm me up”.

“Oooo, is that a challenge big guy?” Tina excitedly followed behind Jay sensing where this was heading.

“Well you made it sound like so much fun so if you let me get changed I-” as soon as the words left his mouth he realized he wouldn’t have time to change tonight.

For Jay he was nearly instantly buried in damp slightly musty fabric and complete darkness as he was enveloped by what he could only assume were the clothes he was already trying to escape from moments ago.

“Hehe sorry I just couldn’t wait, I've been looking for an excuse to do this all week” as Tina walked up to the pile and began to carefully fish Jay out of his own clothes.

“And knowing you wanted it, I just couldn’t wait” as she finally found the tiny body she’d been looking for Tina couldn’t contain her glee.

“Oh my god you look adorable like this” Bringing Jay up to her face to inspect his new diminutive stature she looked over his naked form like a child inspecting their new toy.

“T I know you’re excited but I am absolutely freezing and this is kind of terrifying I didn’t think you’d make me this small so soon” Jay’s whole world had gone from pitch darkness to being raised to his girlfriend’s enormous face at speeds equivalent to a rollercoaster.

Standing on his girlfriend’s bed sized hand he estimated his size to be 6 inches.

He was now staring up at a face the size of a small house as it suddenly began to speak, thankfully in a whisper.

“Aww I’m sorry babe I just had so much fun when I got tiny so I wanted to share that with you” she said with a slightly apologetic look on her face.

“For now let me help you out with those chills hehe” as she finished her sentence Jay found himself in slightly cupped hands as Tina opened her mouth wide.

Suddenly Jay was enveloped in Tina’s warm breath as she created a warm breeze with her mouth for him. It smelled slightly sweet like she’d prepared for this with something sweet to eat.

As the feeling returned to his fingers Jay gazed up at the enormous mouth before him.  His fear began to fade as he realized this giant was still the same caring woman he fell for long ago.

“Thanks for that babe but I was hoping for a longer term solution and I don’t exactly want to go in there” Jay said pointing at the cavernous maw before him.

“Just a taste I promise” she teased him bringing her mouth closer before pulling away

“But don’t worry I wanna make sure you enjoy every bit of this like I did” as she said this she began to walk back towards the couch.

“Although I do still have a teeny bit of work left to do so I can’t give my little man all the attention he deserves quite yet” 

Jay was suddenly brought lower as her hand guided him towards the pocket of his hoodie she was wearing. 

“So warm up and relax in here while I finish things up and I’ll be right with you”

With that Jay was left in the tent sized space of the hoodie pocket “Well it’s nice and toasty in here at least”.

Despite it belonging to him the scent that surrounded him was undeniably Tina’s, slightly of sweat from the warmth and slightly of the coconut body wash she often used.

“At this point I don't remember the last time I wore this thing” He chuckled to himself as he laid down in “his” sweater and settled into a comfy position to wait for his girlfriend to finish things up.

Jay slipped into a nap as he listened to the rhythmic tapping of the keyboard Tina was using above him but before long he was awoken by the commotion made by Tina’s hand entering the pocket.

The massive appendage barely registered as a hand to him considering it was nearly as long as he was tall and far more massive.  Without warning the hand went limp and came to a rest on top of him.

Whether she was doing this to mess with him or try and comfort him Jay was shocked by the strength and weight of her hand, just by placing it on him he couldn’t move an inch.  He struggled in vain to budge the hand but to no avail, he accepted his fate under the hand.

Up above Tina was hard at work albeit at a slower pace while she reveled in teasing her tiny boyfriend with nothing but her hand, as she felt him begin to resist the excitement took her mind off work for a bit as an idea popped into her head.

Just as Jay began to settle underneath it, the hand on top of him sprang to life, the massive digits began to work with far more dexterity than his brain considered possible for objects of that size.

The middle finger deftly pinned him down while the thumb and pointer finger began to massage his crotch, the massive erotic massage quickly got him as hard as could be while the massage transitioned into what could technically be described as a “hand job”.

The massive fingers stroking his erect cock seemed to increase in speed bringing him straight to the edge of orgasm, the massive fingers felt better than a hand ever could as they enveloped his entire shaft.

The feeling of being pinned down and overwhelmed by just one small part of his usually petite girlfriend seemed like something he may just become obsessed with as the fingers seemed to react to his pleasure by finishing him off with consecutive slow and then fast strokes.

His orgasm came powerfully as he spurted a far larger amount of cum than usual, the load splattering all over the fingers above him seemed to elicit a giggle from far higher up outside of the pocket.

The hand left just as quickly as it had arrived and as he lay there panting from the amazing orgasm he just had, suddenly another hand entered, this time with the intent to retrieve him it seemed.

Pulled from the pocket and once more held in front of Tina’s face he noticed the smug expression she wore and blushed a little.

“Someone enjoyed that didn’t he?” Tina asked sarcastically while eyeing the cum that now covered her thumb.

Just as quickly the thumb entered her mouth as she seemed to lick the cum straight off of it and swallow.

The massive load Tina couldn’t have swallowed on her best days had disappeared down her throat in an instant Jay thought to himself as he realized just how tiny he was.

“And while someone was warming up I got plenty done, including thinking up a little game for us” The eager smile Tina wore evoked some unease in Jay but the orgasm he just had made things clear he’d enjoy whatever happened next.

“To make sure you learn to enjoy shrinking as much as I do, I'm going to take two inches off your height every time you cum”.

“Wait, that's about a third of my size isn't it? How small will I get?” Jay was a little worried, he was already tiny from his perspective he couldn’t imagine being any smaller.

“Hehehe well that depends on you doesn’t it sweetie, and besides I got much smaller than you are now, trust me you’ll love it” as she finished speaking she reached for her phone and began to move the slider once more.

The hand he was standing on began to expand as it went from the size of a large bed to the size of a small bedroom, the starry eyed face of his girlfriend staring down at him went from the size of a small house to a two story building.

The exhilaration of his previous orgasm had merged with his fear at his new stature to create a new feeling he couldn’t quite comprehend, he knew he was going to experience a whole new world tonight.

“So what do you think?” Tina asked with a smug expression seemingly knowing how her miniature boyfriend would respond.

The voice that came out of Tina’s mouth was much louder than Jay had been anticipating, she had forgotten to whisper and to Jay it sounded like a massive speaker projecting her booming voice through the air.

“Honestly babe a little nervous but as long as you’re careful I can’t wait for what you have in store next” in comparison Jay’s voice was a faint whisper Tina had to strain herself to hear, the distance between her hand and her ears seemingly too great for her tiny boyfriend’s voice to clearly reach.

“Hehe you sound adorable down there, and don’t you worry I’ll be plenty careful with my precious lil J”

With this some of Jay’s fears were assuaged as the gentle whisper returned and his faith in his partner somewhat overpowered his fear at the overwhelming size difference between them.

“Now that you’re done with work, what were you planning for us to do?” Jay asked unsure what his girlfriend’s plans for him were exactly.

“Well there's this show I’ve been super into lately and it just dropped its last episodes, it just came out today and I’ve been so busy I haven’t had the chance to watch it”. As she spoke Tina grabbed the tv remote with her other hand and began to click through some menus.

After finding the right show and getting it ready to play she began to get comfy on the sofa and placed Jay on the vast coffee table.

Jay took in the size of the world around him and was amazed, even Tina’s coffee mug was taller than he was while his kitchen looked to be hundreds of meters away.

His usually average sized TV had suddenly become far more reminiscent of a movie theater screen, the sight inspired awe despite the trashy reality TV that lay upon it, he recognized the show, a gimmicky dating show Tina would often put on in the background of their home that barely required her full attention to digest.

“And since I know you don’t care for this type of show in the least I figure you can have fun with something much more interesting”

With that Tina lowered her hand down to the table, waiting for Jay to climb on board, Jay obliged albeit somewhat reluctant to leave solid ground at his size.

Tina carefully placed him at the far end of their couch and began to lay down with her feet facing Jay.

“I’d like to introduce you to our next activity, Tina Top Trekking!” she announced in her best fake announcer voice.

“At one end you have your girlfriend’s very cute freshly pedicured feet, and at the other await the lips of the love of your life, and she would very much like a kiss from her now teeny boyfriend” Tina continued in her cheesy impression.

“Can you make it to the end without falling victim to the many dangers that lay between you and your goal? Let's find out”.

With that Tina blew Jay a kiss and simultaneously unpaused her show to signify the start of the event.

Jay standing at the “starting line” of her toes took some time to admire the view of his path ahead, Tina did have very cute feet and the slightly tanned legs ahead of him were certainly going to be a highlight of the journey. 

“Does tree top trekking usually involve ‘many dangers’?” Jay said to no one in particular and quickly began his journey by mantling up Tina’s massive toes which were already chest height to him despite being only an inch off the ground.

As he climbed past it Jay turned and gave the watermelon sized big toe a small kiss, somehow even at this size it was still oddly dainty.

Jay continued up the ankle and onto Tina’s thighs, upon reaching her left thigh he laid himself out flat and squeezed the thigh with all his might, the soft flesh of her athletic yet still tender thighs barely budged despite the effort “I'm totally squeezing  you guys silly when I get back to full size I hope you know” Jay said, seemingly taking offense to the indifference of the legs he stood upon .

Returning to his feet Jay looked up and met the gaze of Tina who clearly had none of the indifference for him that her thighs had,

“Having a nice trek are we?” her voice like a distant loudspeaker vibrated the very air around Jay,

“Danger number one of your trek, the thighs of dooooooom”, with that Jay was gently shoved off of her leg and into the crevice between them as her thighs slowly closed in on him, with nowhere to run Jay accepted his fate and allowed the warm and soft flesh to embrace him.

He could tell she was still being gentle but despite this the pressure of Tina’s thighs was still a mixture of pain and pleasure, feeling himself grow hard he realized the latter was clearly the stronger of the two feelings.

Suddenly the twin flesh pillars that had engulfed him began to shift up and down stroking his entire body in their soft yet firm embrace, the friction and thought of which quickly drove Jay to the edge of orgasm, although he resisted it for a moment the thighs surrounding him seemingly realizing how vulnerable he was gave one final long stroke to drive him over the edge.

Feeling the trembling orgasm of her boyfriend below, Tina slowly spread her legs and gazed down at him smugly while she reached for her phone, “Looks like someone couldn’t handle the pressure could he?” she sarcastically asked Jay who was clearly still recovering from what looked to be a very intense orgasm.

“Well you know the rules baby, two inches isn't a very steep price for the fun it looks like you're having”, with that Jay’s world expanded once again, this time he lost half his height in an instant, the thighs that he could just barely look over moments ago quickly ballooned to twice his height appearing to be several meter high walls closing him in.

“I am sorry to say we don't offer any recovery services on this trek and so you are responsible for finding your way back onto the course” Tina’s voice nearly echoed off the walls of her own thighs from Jay’s perspective, although they also seemed to dampen the booming voice above him to his comfort.

Now facing the task of beginning his now twice as long journey Jay looked towards the treasure at the end of the valley he walked through.

 The shorts Tina was wearing looked like an old pair of her volleyball shorts that she never gave up wearing despite the obvious camel toe and ridiculously tight hold on her ass they had when she neglected to wear any underwear with them which she had clearly done again, Jay had enjoyed her in them many times at full size but the view at this size was captivating.

As he began to approach the camel toe Jay had teased Tina for many times before he began to notice a strongly growing scent, Tina was very much enjoying herself he mused, gazing up from the valley he was in he realized Tina was half sitting up and nearly constantly glancing down at him at every opportunity, it looked like she very much wanted to interfere in his little trek after all.

Basking in the warmth and scent as he approached it Jay realized this camel toe was a perfect opportunity to tease Tina to the edge of her sanity, Jay reached forward caressed the moist fabric in front of him, the lips of Tina’s pussy were nearly the same height as her thighs but the moisture and shape of the material ahead of him gave him exactly what he was looking for, grip.

Grabbing on to the protrusions created in the fabric Jay slowly climbed his way up Tina’s massive crotch, he could hear her breathing get faster up above and felt her heartbeat quicken under his grip, eventually as he crested the peak of her crotch he made sure to give a rough but at her size tender amount of pressure on where he estimated her clit was through the fabric, judging by the motion above him Jay estimated that this was the final straw for Tina.

Suddenly a hand much larger than the last time he had seen it pinched him between forefinger and thumb with a still gentle if but slightly careless grip, suddenly Jay was staring up at his now very clearly horny and impatient girlfriend’s face.

At this size he could see every detail of her massive and utterly gorgeous face, he could make out the blush in her cheeks and the impatience in her eyes, he also couldn’t have hoped to miss the tongue that quickly lashed out and across her lips as she eyed him hungrily.

“Unfortunately my dear you’ve gone and broken the most important rule of Tina top trekking, ‘do not excite the Tina’ as punishment you will have to play a minigame, ‘escape the shorts before I soak you in my cum’” whispered Tina in a slightly rushed tone, clearly hoping to get the minigame started soon.

“Very creative name babe” Jay shouted up at the monolithic face before him.

“Rule breakers don’t get to give sass” with that Tina stood up and lowered Jay gently to the rim of her shorts pulled back the elastic and dangled him above the opening giving Jay a perfect view of what was to come.

Suddenly he was falling, even if it was towards a soft place the drop still left him startled, the soft material of the shorts cushioned his fall and dragged him straight towards his girlfriend’s already incredibly wet crotch. Above Tina sat back down and released the elastic shoving Jay even deeper into the embrace of her waiting lips as darkness and cum coated him head to toe.

The air around him was hot,  heavy and laced with lust as the only thing he could smell was how desperately Tina wanted to cum, she had clearly been enjoying every second of this little game of theirs.

Jay didn’t have to wait long for light to enter but with it came a hand, precise and clearly impatient after all that teasing the fingers above him immediately went to work on Tina’s clit, vigorously rubbing in circles as she desperately chased the feeling of coating her boyfriend in her pussy juice.

Jay realized very quickly that winning this minigame was not going to be an option as the fabric around him was preposterously tight in all directions and crawling through the raging storm of Tina’s masturbation was not a safe bet, with this Jay decided his best idea was to simply get the game over with quickly.

Using the lips on either side of him as handles Jay plunged himself deep inside the massive pussy before him, covered head to toe in cum Jay felt Tina begin to buck her hips and moan loudly in response to his movements, he quickly realized Tina was not going to stop this game before she came so his best bet was to help her along.

Despite not having the reach his cock would normally have Jay was very intimate with Tina’s pussy and positioned himself to massage her G-spot from inside her just opposite where her fingers were on the outside, this clearly pushed her over the edge as Tina’s moans crescendoed, the fingers speed grew even quicker and the muscles surrounding him clenched and loosened wildly, luckily unable to crush him at this size.

As he lay in the cum soaked hammock of the shorts reveling in his “loss” he felt movement up above as the hand snaked its way further down and grabbed his diminutive form once more, this time taking him to fresh air and yet again his girlfriend’s towering face.

Despite her imposing stature the titan sized Tina looked exhausted as she blushed and panted heavily while staring down at the source of her lust. Between heavy breaths she managed to get out “Okay that was a fun distraction but you really ought to get back to your trek or this will take you all night”, Jay had almost entirely forgotten the pretense that led to this situation but figured the rest of the trek wouldn’t be an issue with his primary obstacle exhausted.

Tina wasn’t done speaking however as she lowered Jay to the couch which now spanned several blocks to him.

“Especially after you take your punishment for losing” she continued to speak as she suddenly began to disrobe, peeling her now soaked shorts off and removing her sweater to reveal what lay underneath.

To Jay these simple movements looked like a building dancing before him as he gazed in awe at the now naked form of his colossal girlfriend, his eyes lingered at the now bare C cups he adored squeezing and the nipples he would playfully pinch or suck on from time to time to excite Tina, both of those prospects were utterly impossible at this size as even just one of her perky breasts represented a mound several times more massive than he was currently.

All this completely distracted him from the last thing Tina had said and from the not so subtle motion of her reaching for her phone on the table.

Having not heard a thing she had said Jay was left perplexed as Tina plucked him from the couch he had begun to lay down on as she began to do so herself. 

After she had come to a rest with Jay still in her hands Tina placed him at the crest of her crotch betwixt her neatly shaved bush, for a moment she longed to take his body and plunge it inside her waiting pussy, for the time being she would restrain herself, what she had in mind sounded more fun for now anyway.

“Now you ought to get going baby, this might take you a while so I’m going to rest my eyes for a bit and check on you later”.

“Might take me a while?” Jay thought “It’s not that far, how long does she plan on napping?” he wondered to himself, thinking of ways to wake her when he reached the end of his journey.

“If I were you I would have tried harder to avoid losing but I suppose you won’t mind taking a while when the view is this fine” Tina declared smugly as she reached for her phone.

“Losing? What did I lose again?” Jay thought for but a moment before his entire world, already alien in nature at his size, transformed once more into something he never could have imagined.

“Oh” he said out loud to no one in particular, there was no one around for miles after all.

Small

That was the only word on Jay’s mind at this moment, Tina had in but a moment ballooned from a modestly sized park into an entire landscape, her lips that he could barely make out through the forest obscuring his vision, his supposed end goal now had more in common with the sun cresting the edge of the ocean than anything he could ever hope to reach.

The ground beneath him seemed like the surface of an entirely different planet it pulsed enough to knock him off balance if he wasn't careful and even the pores of her skin represented pot holes to him, the most alien property of all had to be the local flora though, Tina’s neatly trimmed bush had become an entire forest of unsettlingly straight brown trees looming far above, they seemed to be there solely to remind him just how microscopic he truly was.

He was a mite on his girlfriend’s body, likely so small she couldn’t even spot him if she tried, and for some reason that was the hottest thing in the world to him right now.  “Her fetish must be rubbing off on me more than I thought” his voice vanishing into the vast wilderness of his girlfriend’s body as he admitted to himself how much he was enjoying this.

With nothing left to do but enjoy the scenery Jay decided to attempt to complete what remained of their little game even if the prospect of doing so was about as realistic as summiting Everest at this point in time.  If nothing else, getting out of this forest would hopefully give him a better sense of scale and a better view of his new home planet.

The trek took an hour and wasn’t without its dangers, the subtle reverberations of Tina’s heart made it feel like walking in a dream, some footsteps seemed to take him nowhere while others propelled him much further than he intended, this combined with the pore pits meant that each step had to be calculated lest he trip himself, the last thing he wanted was to be injured and stranded on his girlfriend’s crotch, especially considering her quickening heartbeat and the growing smell coming from behind him, it seemed like Tina was having a very good dream. 

But finally he had completed his goal, or at least the reasonable one he set for himself given his circumstances, and it was worth the work, this trek may have been perilous but the view that greeted him as he left the forest behind was worth a thousand treks to Jay.

Before him lay the planet he had come to love, sprawled out in all her perfect and undeniably massive beauty, her head lay gently on the edge of their couch but from Jay’s view it was like seeing Tina’s adorable sleeping face projected on the rising moon for how far she was from him,  Jay’s slightly musk addled mind immediately fixated on another feature, or perhaps two features.

Tina’s normally modestly sized breasts now loomed in the distance ahead and above of him, their size was nearly inconceivable to Jay now but he estimated that they could crush entire city blocks if the goddess that was his girlfriend was to descend upon their city at this size. He pondered to himself whether or not the app could grow things as well, he decided it probably couldn’t as Tina at this size to other people would probably be enough to do unfathomable amounts of damage and there's no way she resisted doing that this long.

The idyllic landscape of his girlfriend quickly plunged into chaos as Tina began to wake from her clearly pleasant dream, the mere act of adjusting herself as she half sat up to wake up was pure chaos for Jay.  In a matter of moments the horizontal plane of Tina’s crotch became a steep angle and Jay found himself rolling back towards the forest he had just emerged from.

In just a few seconds Jay had lost every millimeter of progress his hour of work had earned him before the terrain settled back down as Tina finished waking up and remembering where her boyfriend should be.

“MMMMMM GOOD MORNING BABE”,  the deific voice of Tina shook the heavens above Jay and the air itself trembled in response to a simple stretch followed by a greeting, luckily enough the voice only seemed deeper rather than proportionally louder otherwise Jay imagined he would be deaf right about now.

“I HAD A VERY FUN DREAM AND I CAN’T WAIT TO SEE HOW YOUR TREK IS GOING BABE”, Tina’s voice thundered once again and Jay began to experience an unusual feeling, growth.

After a moment Jay found himself standing twice as tall as the trees that dwarfed him moments ago, although it wasn’t lost on him how small he still was he appreciated the height for a moment before he heard a snicker above him.

“Aww did someone enjoy my pubes a bit too much? That’s exactly where I left you pervert”, Tina’s quieter albeit still quite loud voice called from above.

“Well I suppose take all the time you need but I’m going to have to keep busy while I wait”, with that Jay’s size vanished once again as the much more familiar feeling of shrinking filled him and brought him far below the forest canopy once again.

After this pure chaos reigned once again, minor earthquakes rattled Jay’s world as a hand the size of a city block soared overhead, his nerves spiked as he realized that hand was heading straight for him, he closed his eyes and braced expecting to become a microscopic smear on his girlfriend’s crotch.

Opening his eyes he realized quite fortunately he was still alive and the hand he had been so afraid of was still miles above him, save for it’s middle finger which extended behind him down towards what he assumed to be Tina’s clit although the woods made it hard to see clearly.

Suddenly the moans began, quiet and subtle but still bassy and all encompassing, in conjunction with this the earth below him had become as unstable as a bouncy house, the subtle motion of Tina playing with herself robbed Jay of his only stable ground.

“MMMMM GOOD LUCK DARLING I’LL BE WAITING” Tina’s voice dripped with lust and smugness in equal measure, she was enjoying this far too much.

For Jay the idea of even clearing the forest again under these conditions seemed ridiculous, but whether it was Tina rubbing off on him or his own impetus he found himself wishing to see the view from the “south” side of the forest now.

And so Jay began yet another trek under even worse conditions than before, luckily he was deposited much closer to the south end when Tina woke up.

The trip went by in a haze, the heat and smell of Tina’s pussy seemed to call for Jay as he stumbled like a man possessed towards their source, Jay’s entire mind felt as though it was overwritten and filled with absolutely nothing but lust, only the keenest remnants of his consciousness realized this must have been more than just a fetish rubbing off on him.

Soon enough he arrived at the edge of the forest albeit a bit to the “east” of where he had intended, the sight that filled his view was nothing short of mesmerizing, a digit the size of a skyscraper deftly teased the massive clit that once used to be a hidden gem for Jay’s tongue but now dwarfed him several times over even whilst merely peeking out from the folds before him.

It defied all reason to see such massive objects move at such a speed but the artful maneuvering of her finger to tease herself and occasionally plunge deep within the lake sized pussy of his girlfriend had Jay completely entranced. The one remaining shred of sanity was the only thing stopping Jay from sprinting full force towards this display and plunging headfirst into the finger that would quickly turn him into a red stain across his girlfriend’s clit.

It was a surreal thing to witness, if it weren’t for the fog in his head it may have simply felt like an abstract movie from this angle, but to Jay’s now completely addicted mind it was simply  watching his goddess of a girlfriend please herself before the mite that was her boyfriend.

Jay couldn't do anything but masturbate himself, the orgasm arriving swiftly and with a force he hadn’t thought possible as he had apparently been hard for quite a while before this. 

Seemingly in response to this despite the fact Tina could neither hear, feel, or see the mite worshiping her at this moment. Tina slowed and stopped herself as well.

“NOW LET'S CHECK IN AGAIN ON MY LIL J WHY DON’T WE”, as he heard this the now familiar feeling of growth came across him as he found himself once more at his roughly millimeter size.

“I swear even at the size of a dust mite you can't resist me can you babe? Even further from the goal now too” The mocking tone was quite evident as Tina looked down on Jay with a smug look on her face.

“Unfortunately going backwards is against the rules here at Tina top trekking so I have no choice but to disqualify you and administer your punishment”

“There were rules to this thing?” Jay’s now slightly recovered mind and mouth managed to eek out.

The massive hand behind him quickly placed itself down next to him at a far more manageable size albeit still that of a baseball diamond, with the help of some soft flesh Jay managed to climb atop it and was quickly lifted straight up to Tina’s waiting face.

The previously moon-sized face was now right in front of him and at the far more modest size of a sheer cliff face stretching straight into the heavens as he stood before it, the massive orbs of Tina’s eyes focused on his diminutive form.

“The fact that this is normal to me already kinda feels weird” Jay said, testing Tina’s hearing while he thought to himself.

Tina having clearly not heard him began the closing ceremony of Tina top trekking: “Your reward for finishing was going to be a kiss from your incredible and perfect girlfriend but alas I have no choice but to punish you and revoke your prize”

“How could she even safely punish me at this size?” was the only thought that ran through Jay’s head before she continued.

“Your punishment will be a kiss!” the whiplash of the two contradictory statements stunned Jay for a moment.

“However I get to choose the type of kiss, and I have decided that you shall give me a french kiss at this size” Tina’s voice bounced with playful enthusiasm as she declared her intentions to her ant sized boyfriend.

With this Tina brought her hand to her lips, opened her mouth slightly and from it snaked her tongue, these seemingly small motions were mind-blowing for Jay as he witnessed the endless abyss of Tina’s maw open before a serpent the size of a building landed mere meters from him.

“Oh on aye aing” rang out from Tina’s cavernous maw as she tried to speak with her tongue out, however Jay got the message and realized safety may not have been on Tina’s mind when planning his punishment.

With no way to communicate with his unfathomably large girlfriend Jay began to approach the tongue with much trepidation, upon getting within a few feet of the tongue something he couldn’t have predicted happened. 

The tongue darted forward what must have been less than a centimeter colliding with Jay, he stuck to it immediately due to the saliva before it retracted into Tina’s mouth in less than a second.

The following moments were like a mouth themed roller coaster as light flickered in and out of Tina’s mouth, Jay was thrown all about as the booming sound of Tina’s voice nearly shattered his eardrums.

“WELL DID YOU DO IT?”, was all Jay could hear as he realized Tina couldn’t see or feel him in her palm and was trying to check on him.

“JAY!?” Tina exclaimed clearly having realized he was no longer on her palm.

The subsequent minutes were disorienting as Jay was tossed around the cavern with very little in the way of lighting, save for one moment.

In a moment of stress Tina curled her tongue back and caused Jay to collide with her uvula, the saliva coating it yanked Jay from his position on the tongue and placed him in a far more precarious one, dangling directly above and staring down into Tina’s throat, fear gripped him as all Jay could do was pray he didn’t end up the meal of his monumental girlfriend.

The sound of Tina’s shock at where she found him was the next thing he heard as she began to slowly regrow him in an attempt to locate him.

The increased weight immediately freed Jay from his captor before causing him to plummet straight towards a far worse fate, at the last moment he grew to the size of 3 inches and was now luckily too big to accidentally swallow.

The following moments passed in a blur as he was spat out, profusely apologized to and given a much needed relaxing shower in the sink.

“Okay but so other than the almost getting eaten part how did you like it?” Tina asked, interrupting the shower she had set up for his now four inch form.

“Okay I may have to admit the size thing is pretty fun, as long as it’s with someone more careful than my massive clutz of a girlfriend” Jay teased.

“You totally loved every second of it” Tina declared smugly.

“Only a bit” Jay said, unable to hide his raging erection from the towering smug face right behind him, a face that absolutely said this was something they’d be doing again.

Heat, exhaustion, and sweat rapped on the door to Tina’s mind but were paid no heed as the sheer volume of lust within simply occupied too much space.  About ten minutes had passed from the moments she spent bent over and fucked ravenously by Jay before being shrunk down to be used as his toy for the day but Tina’s desire had seemingly grown exponentially since arriving in his underwear.

The massive tent-like area she found herself within was just barely illuminated by the faint bit of light piercing through Jay’s black boxers.  The only other things that accompanied her within were the absolutely intoxicating stench of sex and its source.  At her size of two inches the massive semi erect cock of Jay was already over twice as long as she was tall and its girth made it tough to hold onto, her hands only finding purchase on particularly thick veins, a problem that aroused Tina to no end as she struggled to ride the monster that just finished ravaging her minutes ago.

Each pulse of Jay’s heartbeat rocked Tina reminding her of her job here, it was her day off and Jay, having been on a bit of a dominant streak after getting comfortable with the app, decided Tina was to be his toy for the day.  Tina absolutely adored this dominant side of Jay and started to get wet even as Jay simply  described her duties for the eve. There were only two.

Tina decided it was about time to start on her first task, but the overwhelming aroma that surrounded her simply obfuscated every thought that passed through her head.

Every thought but one.

In the next moment she was grinding vigorously on the massive organ below her, gripping it tight for support and using every ounce of strength she could muster given her dreamlike trance she threw herself against Jay’s throbbing cock.  Sparks shot through her body as her soaking pussy found groves and veins, each stroke of her body seemed to have the same effect on Jay as his penis grew to full mast and became even harder to grasp.

Tina threw herself into her passionate bull ride as the ever increasing bloodflow to Jay’s cock threatened to knock her loose, the reward of yet more pleasure keeping her moving as both the fog that dominated her mind and the body that dominated her own became her only thoughts.

A ray of light came to pierce that fog as Tina was reminded of her first task, the band of Jay’s underwear was pried open and soon followed a hand to abduct her from her heavenly prison.

Through slightly panting breaths Jay muttered “Well that certainly didn’t take you long now did it?”.

“Fuck me Jay, god just please fuck me right now” was all Tina’s addled mind could render, unsure of whether Jay heard her or not.

The answer came a moment later as the hand holding her flung her onto the bed she had laid in minutes previously, the aroma they left behind still very much present.

Tina found the fog clearing from her mind as she began to grow, as it cleared she recalled her first task, simply getting Jay hard again.  The reason for the task as well as the second both returned to her just as quickly as she stopped growing, now back at her original size, or perhaps a tad smaller? It appeared the fog of lust devoured her sense of scale just as ravenously as it had her rational mind.

Before even a single rational thought could enter her mind something else had beat it to the punch.  Jay.

In one moment she realized that she had vastly overestimated her own size and in the next the fog returned in full force as Jay pinned, used, and fucked her like he’d promised to the previous night.

For Tina the next several minutes were lost to the fog.

Pain, pleasure, sweat, heat, the brief thought she may split open from the massive organ within her, and finally an all encompassing moment of euphoria as she delighted in being used as a toy for the pleasure of the love of her life as he came inside her.

Suddenly she was laying in bed gazing up at the titan that was her boyfriend as she shrunk down once again. Jay towered over her several storeys tall, his massive form dominated her mind itself as she couldn’t help but stare while he absentmindedly fiddled with his phone to adjust her size while putting on underwear.

Having gone through this exact scenario less than an hour ago Tina knew what came next, she was unceremoniously thrown back into her home for the day and once again began to acquaint herself with her roommate.

Using the measuring stick of Jay’s cock Tina put herself at around six inches, the oppressive heat, scent, and moisture of Jay’s underwear clung to her and threw her into a frenzy once again.

Now at a much more capable height Tina quickly wrapped her arm around Jay’s now flaccid cock and pressed her now diminutive tits against it along with the rest of her body trying to stroke him with her entire self.  The same impulse drew her hand down below as she disregarded the cum leaking from her pussy to plunge her fingers deep inside herself and along her clit at a speed she hadn’t thought possible.  

The furious masturbation session brought Tina deeper into the fog of her arousal, the musky tent pitched by Jay’s cock was the perfect setting to drive her completely mad as she orgasmed again and again, all the while feeling Jay’s penis spring to life once more over the course of half an hour.

Almost as though feeling the shuddering of yet another orgasm Jay quickly reached into his underwear and grabbed Tina’s diminutive form far more roughly than he would have had she not been so into this.

Once again Tina found herself yanked from her new habitat and thrust into the bright and soft world of their bedroom, immediately she felt herself growing once again and once again she found herself stopping short of her full height by a few inches. Instantly her eyes found Jay’s as she stared at him intently awaiting her orders.

“Off the bed and on your knees now” Jay demanded in an authoritative tone.

Tina’s body having spent the past hour or so worshipping the man before her, took the words as law and began to move before Tina’s mind could catch up. Quickly the disheveled and cum soaked Tina was on her knees before the now seated Jay.  At her slightly diminished size everything about Jay just seemed so much bigger, nearly dominating her with his mere presence, but most of all was his now massive cock, on a good day Tina could hardly handle it and tapped out of deepthroating rather quickly.

She quickly realized as Jay’s hands landed on the back of her head that toys do not have that option.

 Suddenly Jay’s massive Cock was in her mouth and deep inside her throat, on any other day Tina’s gag reflex would have had her pulling away but the fog of arousal that continued to cloud her mind convinced her to give in and be nothing more than Jay’s toy regardless of her body’s reaction.

Over the next several minutes Jay used Tina’s mouth as his personal fuck toy, holding Tina by the head and vigorously pumping his cock deep inside her left a bulge down her throat, the sight of which drove Jay mad with arousal driving him to the edge in mere minutes.

Jay’s enormous load emptied itself straight down Tina’s waiting throat as he pulled her in for one last thrust, Tina was drooling and practically on the brink of cumming herself from the situation, she swallowed down every drop of the heavy load gladly and showed Jay her open mouth as though to show off her accomplishment.

“You know you’ve been a very distracting toy today Tina, I think I know exactly where you’re going to spend the rest of today”, with that Tina began to dwindle down once again, quickly she found herself half an inch tall on the floor staring up at her god of a boyfriend.

Divine judgment came in the form of his hand descending from the heavens and delicately plucking her from the floor.

“I hope my toy is ready to do some cleaning, I expect plenty of work from that tongue of yours, this might take a while”, were the last words Tina heard before she saw Jay pull back the foreskin that covered his now deflated yet still somehow half mast cock.

Bringing her to the rim of his uncovered cockhead Jay blew a kiss at the diminutive form of Tina he knew was staring at him like a god right now, pressed her tight against the rim of his head and dramatically made a show of swiping her size slider all the way to the left.

Tina could do nothing but watch in anticipation as the god mile above her robbed her of every last millimeter of her size.  Instantly she dwindled away to nothing, less than a grain of sand, staring up at Jay she could barely make out his face anymore due to the sheer distance between them, him a god and her a toy.

The sky went dark as the tsunami of Jay’s foreskin flew overhead instantly plunging her into an alien world of sheer darkness, accompanied only by the raw smell of both Jay’s and her own cum.

The sheer weight of the musk surrounding her dropped her to her knees once again as she began to furiously masturbate while licking the spongy slick surface beneath her, today she was a toy for a god and obeying him was the only thing on her mind.

“Staying here might get a bit addictive” were the final salient thoughts she formed before getting down on all fours and succumbing to the primal urges her environment bade her to.

Tina would keep no memories of what happened down here but her body would tremble with urges she could barely fight to come back over and over again.
