Really short GTS thing

(It's short, there's no exposition, super simple, basically pure smut. Possibly to be added to later.)

The first thing she did when she entered the room was to walk, swaying her rotund hips just so before turning around, looming over your position on the chair.
You were a meager half centimeter in height, so the sheer volume of her filled your entire periphery.
She looked behind her back, down at your tiny body sitting in the middle of the huge chair. A finger picked a wedgie out, and she let her pink, tight panties snap bouncily against her rear the next moment. She giggled, and watched you fixated on the sight. It filled your entire vision, and soon, it would dominate your entire space a hundredfold. She slowly crept back, the titanic spheres hugged by the pink fabric hovering cutely over you.
She slowly lowered her ass on top of your body, and you felt the weight come pushing on top of you, forcing you onto your back, flattening you as she sat down. The pink fabric became your world, shoving its way over you until you could see nothing but a single solid color, before darkness came, no light being able to pierce through her to reach you. You could only feel her gigantic rear on top of you, could only hear her giggling and bouncing on top of your tiny, frail body and grinding her hips into the chair, eliciting strained groans from the chair as it struggled to support her weight as much as you were. You hear other sounds, as well, like soft laughter from your captress, the sound of tugging and snapping, muffled by the huge pressure on top of you.
As your eyes adjusted to the darkness, you started to see between the fibers of the titanic underwear, your tiny body blessing you with the advantage of seeing what lay beyond. Soon, the dim but tantalizing sight of her taint filled your entire vision, as it pressed, with crushing intent, heavily down upon you. She sighed with joy at the feeling of you underneath of her ass. She straightened in the chair, and her cheeks came together, pushing and crushing against your sides, forcing you tighter and tighter into a soft but tremendous weighty prison underneath her ass and panties.
The chair groaned again, and you briefly felt almost like you might pop, before she leaned forward in the chair, smothering you and pushing more of her front into the chair on top of you. The darkened sight of her taint between the threads changed to a vision of her folds, which seemed almost to glow in the darkness, like a beacon teasing your minuscule body. She bounced in the chair again, nearly crushing you underneath her entirely, before with seemingly no warning, she mercifully stood.
Blinded briefly by light, you struggled to adjust, your sight dominated by bright pink, your nostrils flooded with her dominant scent. You could hardly move, and struggled to gather the energy to lift your neck to look up at your giant girlfriend. She had taken her bra off while she was sitting, her C-cup breasts fallen and teased, the marks from her heavy groping of her own tits to pleasure herself visible on her beautiful skin. Her erect nipples seemed to perk as she turned back to look at you once more, a grin hidden by the angle forming across her face.
Deft fingers slipped into the sides of her panties, and she tugged, anxious but patient, at the sides of the pink fabric, and they fell around her knees before being held tense by her legs moving slightly apart. Her thighs shook as she shuddered from the sensation of the air teasing her down there. Her eyes fluttered open after being closed while she took in the sensuous atmosphere. She looked down at your position. She giggled another time, and let her panties fall down around her ankles. She leaned down to pull them off her feet, the titanic ass pushed back over you, like two sexy moons, damningly heavy but undeniably alluring. Finally, she stepped out of her last article of clothing, and a foot fell to the side of you. The toes crinkled and tapped against the chair, as she stood hungrily over you.
Then, she turned around, and stood, legs to either side of the chair directly over you. Your insignificance, half centimeter of human, beneath the rotund ass, the gargantuan and shapely thighs which met to hug the sides of a tempting and pretty vagina, and the pounds and pounds of human above them, including the medium but unnaturally hefty and firm boobs, was made unquestionably clear. She lowered another time, wet and hot breath audible, filling your ears.
The last two things you see before her ass cheeks and pussy filled every corner of your vision were her hands as they moved back to massage and feel at her perked nipples and at the rounded mountains on which they stood, the second thing being her huge face, which peeked over them down at your puny body on the chair. A warm and comforting smile on her face, she slowly and warmly lowered further and further. Soon, the only things you could see were her gigantic buttocks, between them a taut anus, easily larger than your half centimeter self, and further up, the vast plain of her perineum, and past it the blissful curves which met and retreated, forming the labia majora and minora, a complete and perfect vagina, and situated atop it was a clit, which a single finger hovered above. Then, these gifts came grinding on top of you, filling and blacking out your vision, drowning the light which was meant for your eyes in sexy, heavy, bouncy, loose, but not too loose, angelic naughty bits. Your girlfriend straddled the chair, straddled you, and grinded every bit of herself against your puny, helpless body. The chair groaned as your tiny body became incredibly familiar with each inch of her gigantic rear end, each buttock getting special attention before you were pushed and ground in between them, the huge size difference trapping and pushing you wherever she pleased, forcing you into total submission as you were pulled along for the ride, and each girlish part rubbed itself sexually and forcefully on top of you, pushing in your face, almost collapsing your chest, nearly crushing your crotch, and preventing you from even thinking about moving your arms or legs. Her huge taint grazed over you, and you felt the invasive but not unpleasant smell from between her cheeks be replaced by the smell from your next destination. She lifted briefly off the chair, giving you the briefest sight into her actions. Not even a single inch above your tiny body, her pussy was parted by two fingers, which readjusted and pushed the two lips further apart. You saw deeply into the slick cave, but you couldn't take in the sight before she once again, forcefully thrust herself against the chair, the shock throwing you upwards, inside of her. Her lips closed, and a finger felt its way inside, meeting your backside. It forced its way against you, pushing you through cascades of sexual flesh and fluids, before you finally met face-first with the spongy and quivering surface of her cervix. You briefly felt at it, finding a hole large enough for you to fit. You parted it, and pushed your legs into it, tapping at the gigantic fingers to signify your readiness. The fingers pushed on your head, and the hole slurped you up, by the waist, by the shoulders, and finally it swallowed you entirely. The finger could go no further, and retreated back outside. You groped at the tight constricting tube in which you found yourself, pushing yourself deeper and deeper. Eventually, you tumbled outward into a pitch black, fleshy and alive space, flopping face-first into thick, pulsing flesh and tasty liquids. You felt your tiny form against the huge chamber, and curled up, letting yourself be gently rocked to sleep. You blew a kiss in the direction of your girlfriend's face. At least, what you assumed was the direction of her face. It was hard to tell up from down when you were inside of her womb. The ground shook like an earthquake, her entire body being rocked by her giggles, and soon, you were lulled to sleep by the rhythmic contractions of her orgasm. She would pull you out in the morning, and then you could have some different fun. For now, however, there was nothing that could be done. You resigned to slumber within the gigantic confines of your girlfriend's incalculably immense vagina.
