You're Tom, you have the shrinking virus and this is your story.
Many men have been affected with the shrinking virus but most were nowhere near as lucky as you. When most men shrank they would never be seen again, most crushed by shoes in the streets or sat on unaware in their own homes by those they loved, many of those men are still probably out there trying to get someone to just see them and failing over and over but you, you were one of the rare ones who happened to already have an amazing girlfriend who took great care of you when you shrunk. She was beautiful and kind and had a soft spot in her heart for all things weak and vulnerable so it was natural that she really stepped up when you shrank down.
The only complaint you've ever really had was about how clumbsy or forgetful she can be, there were plenty of close calls where she knew where you were but got distracted and nearly sat on you or stepped on you, one time she forgot you were sharing a meal and she nearly ate you, another time she put you on a table "just for a second" while she did something then forgot you there for an entire day. These times sucked and you always wanted to be mad at her but it was still better than the alternative of going it alone in this giant world. Especially since your condition was permanent, not like many of the others who took medicine to keep the shrinking episodes at bay, you were gonan be stuck like this forever.
This day started just like the others, Britney, your girlfriend, was taking you for a walk along the canal and she kept you in her back right pocket. You loved this, one of the upsides to having the permanent version of the shrinking virus meant you didn't have to worry about shrinking smaller when you got aroused so you totally let yourself get aroused at the compressing and flexing of Britney's ass cheek muscles. Each step felt greater than any sexual thing you'd ever experienced before becoming a tiny. Britney's ass pressed against you and moved your 'member' around from side to side, up and down, and always applied the perfect amount of pressure to keep the pleasure rising. It also helped that she had an amazingly perky bubble butt and also that her pants were always the perfect fit so the rides in the back pocket were never too loose and never too tight, well sometimes when she bent over it got really tight.
Britney never acknowledged it but you always suspected she knew exactly how she made you feel while riding that back pocket, you noticed she would often walk with extra intent that made her walk look sexier than normal but also ensured her ass cheeks would focus in on the pleasure giving movements, almost like every step was a sensual lapdance. On top of that it's almost as if she always knew when you were about to climax because she would usually find some way to increase the pleasure right at the exact moment by bending or flexing or stretching just the right amount to to provide maximum pleasure.
So here you are, enjoying one of the few perks of the shrinking virus as your amazing giantess girlfriend pleasures you with each seductive step, and you fell the climax coming, as if on que her steps become more powerful and press more intensely against your member as her ass cheek flexes and contracts, "here it comes" you whisper to yourself with nothing but extacy in your voice, right as Britney leans against a guardrail to enjoy the view, her ass sticks out and leans upward as her she slowly rises onto her tippy toes, it feels SO good! "uuugh" you finish.
Her butt gives a slight wiggle as if to signify it was proud of the amazing pleasure it had provided you and you barely noticed to rapidly approaching footsteps, Britney definitely didn't notice and when you turned to see what it was your eyes widened in shock and fear when you realized it was some other girl, Britney's friend probably, quickly shuffling up behind Britney with her hand extended and palm exposed, you know she was about to give Britney a surprise ass slap, with Britney being bent over the railing like this she might as well have been asking for it.
"URGLA NA!!" You try to yell for Britney's attention and also to tell this girl not to do it but your words get all jumbled into some incomprehensible sound, not that either of them would have been able to hear you anyways
*SMAAAAAAAACK* The sound thunders and explodes as her hand makes contact with Britney's left ass cheek, you grip your ears in pain and scream at the top of your lungs but you can't even hear your own voice through the now tonal ringing that drowns out any other possible noise. Slowly you hear muffled noises through the ringing and bit by bit the high pitched tone reduces and you're able to hear the conversation above, Britney sounds pissed but also destraught.
"My Boyfriend was in that pocket you bitch!" you hear Britney scold up above, you'd never heard her mad like this before. "I swear if you hurt him I'll...I'll!..." then just tears.
You began yelling up to Britney, you knew she couldn't hear you but you had to do something to console her and stop her from crying "Babe! I'm in the right pocket! I'm ok!"
"I'm so sorry Britney" you hear the other girl say sincerely.
"Maybe he's ok" She then adds
"Maybe you're right" Britney says with hope in her voice as she reaches back into her left pocket, her fingers slide in oh so gently as to not hurt you as they slowly make their way to the bottom of the pocket, then the gentleness dissapears as her panic sets in and her hand shuffles furiously around the pocket checking any possible corner for you until, defeated, she finally removes her hand from the back pocket.
You assume that her next logical step when she realizes you're not in there, dead or alive, will be to realize it was the wrong pocket or at least to check the other pocket just to be sure but instead you hear a statement you weren't expecting. "I think... I think he fell out somewhere on the way!"
"What? no baby I'M HERE!" you yell again, more frustrated this time.
"Don't worry, we'll find him." the girl reassures Britney as Britney gives her a tight hug.
"Ok let's look for him" The other girl suggests and the 2 girls began retracing their steps along the walkway.
These steps were not seductive, they were not sensual, Britney was rushed and her quickened step was bumpy and turbulent. You kept trying to yell up to them but the constant bouncing and jiggling of her ass cheek was so chaotic that you could barely manage to get any words out at all, let alone yell them.
After several, unpleasant minutes of this you catch your first break, the girls have stopped somewhere and are discussing you and how they hope to find you while you relax against the fabric of Britney's jeans and try to catch your breath after that exhausting ride.
Slowly you feel Britney's ass cheek flexing and moving again but not in the rushed, bumpy was as before, she's turning not walking. As her body moves around you peak over the side of the pocket to see a bench down below and make out the words "Let's just sit and think.." from the other girl above.
The 2 girls are debating as Britney stands right before the bench, she seems to be telling the other girl that she wants to keep looking for you and the other girl is trying to convince Britney to sit and make a plan. You're really hoping Britney doesn't take the other girls advice because the wood of that bench looks hard and you'd never been sat on by your girlfriend before, you very much doubt you could survive the pressure.
Below though, something distracts you from the current situation as your eyes adjust to try and make out what it is, it's...it's another tiny! and that guy looks scared, he's waving his arms at Britney's giant oblivious butt, trying to get her attention or trying to stop her from sitting. You know you've done this exact thing in the past but from this angle it looked really futile, it was pathetically obvious how useless his attempts were.
You're snapped back to the reality of your situation and forget about the other tiny when you hear Britney's words "ok, fine" right as she begins to descend. You feel a quick drop in your stomach followed by the increasing pressure of her butt cheek pressing you into the fabric of her back pocket, to top section in perticulat is pushing deeply into your ribs as her ass bends more and her muscles flex at an alarming pace. Pain and fear are all you know in this moment until the last thing you see before her ass makes contact with the bench in the face of the other tiny below, he somehow looks more scared than you feel.
Britney's ass lands with a boom as it hits the hardwood surface of the park bench, the vibration hits you with all the momentum and power of her giant descending body.
Her back pocket wraps around you like barbed ware as her flexed ass cheek shows no mercy in its immense pressure.
Still, you're alive...for now, and despite all the pain your mind begins to wonder what happened to the other guy.
