Iris West Allen had been dealing with Time Sickness for a few weeks now, a mysterious condition that caused sudden temporal disruptions to occur at random, pulling her into different moments in time and even different timelines against her will.
She assumed she was starting to get the hang of it, able to tell through intuition when it would activate, even though her destination was always a mystery.
One day, she'd spent an hour watching the Beatles perform live before her return to the present. On another, she spent a day walking around New York City during prohibition.
It wasn't always bad, but that didn't mean it was always good. Iris's confidence in her intuition was about to prove that as she decided to make a rare appearance at the Central City Citizen, predicting that she wouldn't leap through time.
Iris was getting ready to leave her office when the sensation struck her. She was about to time jump!
"Oh, crap..." was all Iris could say as before she disappeared in a flash of light, one moment she was there, and then the room was empty.
"Hey boss, I..." Allegra spoke as she opened the door not a moment later, swearing that she saw Iris walk in here earlier and wanted her to proofread her latest article.
"Hmm, I guess she can do it later." Allegra shrugged, closing the door, unaware that Iris was now traveling into the future.
--- The Year 2049, Nora Allen's Apartment ---
"Ugh!" Iris grunted as she landed in a dark box, unable to see her surroundings as she landed on something soft. The smell of laundry and perfume filled her nostrils.
"What the heck? Where Am I?" Iris asked, taken aback by this strange turn of events. Usually, she had some inclination as to where she ended up when traveling through time, but she was utterly clueless.
That all changed as her surroundings shifted beneath her, sliding in the same direction that light was suddenly appearing from, which served to illuminate her surroundings.
But what she saw as a result horrified her to the core. She tried to gasp in response, but her breath hitched at the back of her throat as she recognized a massive figure appearing overhead.
It was Nora West-Allen, her 26-year-old daughter from the future. Who appeared before her at a gigantic size, dressed only in a towel. Overshadowing Iris's height dozens, maybe even a hundred times over.
"N-Nora?!" Iris stuttered in a panic, eclipsed by her giantess daughter, coming to the realization in the back of her mind that she had somehow shrunk down to the measly size of an inch tall.
Her gaze confirmed this fact as she shakingly stared to her left, then her right, discovering that she'd somehow found herself trapped in Nora's underwear drawer of all places, surrounded by a sea of hipster panties, thongs, and bras of various sizes and colors, looking down to see herself standing on top of a stylish purple thong.
"Oh, there it is," Nora announced, laying eyes on the same thong, somehow overlooking Iris. Who was smaller than most of the tags on her underwear in her panty drawer.
"Wait, Nora! Down here! It's m..." Iris shouted, trying to get her future daughter's attention, watching as her hand began to reach into the drawer before her world became a whirlwind of movement, which was just one of the many ramifications of having a daughter with Super Speed while you're super tiny.
One second, she was in the drawer. The next, she was lying on Nora's bed with the rest of her clothes for the day and a severe case of nausea, recovering just in time to see Nora's towel drop to the floor, revealing her naked body in all its glory, her 34C cup breasts defying gravity as they appeared to hang in mid-air from her chest.
Then, she watched as the giantess Speedster began to roll her wrists in a high-speed circular motion, blowing back her hair and helping her dry it faster than even a futuristic hairdryer could ever hope to achieve, causing a mist to fall onto Iris as the moisture escaped her shoulder-length locks, her chest bouncing without boundaries as she rolled her shoulders up and down.
"Nora! Knock it off! I'm talking to y..." Iris yelled, trying to assume her 'Mom Voice' in the hope that her future daughter would take notice of her, but she was going way too fast this morning to stop and examine her thong for shrunken people.
Before Iris realized it, there was a flash of purple and yellow lightning. Suddenly, she was no longer on the bed but on the ground, looking up more than a hundred feet to see Nora's perfectly sculpted rear hanging over her with the thong already wrapped around the brunette's ankles.
Her only saving grace, sparing her from being neck-deep in Nora's buttcheeks at that exact moment, was a perfectly timed text message that distracted her.
Maybe it was an alert from the CCPD or a report on Metahuman activity for XS to handle. It could have even been a random text from one of Nora's friends. It was impossible to tell from her current position, but Iris couldn't continue sitting still, waiting for Nora to wear her.
Deciding to make her escape too late, as Nora shrugged her shoulders and finished getting dressed at super speed.
In the blink of an eye, Iris went from trying to climb out of Nora's thong to being rocketed between her rear cheeks, surrounded by their warm embrace from all directions.
As if things weren't bad enough for the shrunken reporter from 2021, her situation somehow got worse only a moment later as Nora pulled her jeans under the cusp of her round behind, performing a few speedy hops to get them over her shapely rear in less than a second, confining Iris to a dark, damp, and intensely personal space.
Completely dazed, Iris reeled from the relentless impacts of Nora's endless sea of ass flesh, feeling as if she'd just been strapped to a mechanical bull and left to endure the highest setting for an hour.
"What the hell are jeans made out of in the future?' Iris huffed in a daze, wondering how Nora could be so rough with the denim fabric without them splitting right down the middle.
One thing was for sure, she definately took after her mother. Iris's ass had ruined their fair share of jeans in the past, and based on how tight her surrounding were, Iris wouldn't have been surprised if Nora's jeans tore any moment.
Nora took a moment to walk at normal speed to a mirror in the corner of her room, turning to check out her ass in the mirror, grinding her cheeks together with each step as the motion sent Iris tumbling and jostling between her buns with each new step forward.
"Ooof! These are getting a little small. Must have shrunk in the wash again," Nora announced, patting her right cheek with her hand, sending ripples through her flesh that shook Iris's entire world.
Nora turned back from the mirror, which witnessed her ass cheeks rise and fall. All while Iris rolled helplessly between them like a powerless piece of lint, defenseless to stop the onslaught of her new hosts as her daughter carried on without a care in the world, not even realizing that her mother had come to the future or that she was shrunk and trapped between her butt cheeks as she swung her rear over the bed to pull on her sneakers.
*WHUUMP!!*
Nora dropped her full weight onto her memory foam mattress, which contorted to her every curve as she reached forward and pulled out a pair of grey Converse Chuck Taylor All-Star sneakers with a purple stripe running across the side and pulled them over her white socked soles, the soft give of her flesh pressing against her from all sides, the pressure was intense, and the heat quickly rose to unbearable levels.
Iris tried to yell to get Nora's attention, but she was just too heavy. She could barely twitch her little fingers, let alone open her mouth to scream, certainly not loud enough for Nora to feel or hear her.
"Mmmphhff!" Iris's muffled cries for help never escaped Nora's thong as she shifted from side to side before finally standing up and doing the one thing Iris was dreading the most. Using her speed to leave the apartment.
Thankfully, the reality wasn't nearly as bad as her imagination played it up to be, but that doesn't mean it was any better. Due to the anomaly known as Flash Time, so long as Iris was in direct contact with Nora's ass cheeks, she moved with them as if time was flowing normally. Which was good in one aspect because it stopped Nora's ass from grinding her into a fine paste in a matter of seconds, but at the same time horrible to experience as it dragged out her two-minute run at 600MPH to a horrific 40 minutes of pure agony, ensuring that she became familiar with Nora's every curve as she was drawn deeper and deeper into her buttcrack, her ass cheeks jiggling and swaying with her every stride in a seemingly endless cycle.
Nora had yet to break a sweat, but after all that time, Iris was soaked in it as the two finally arrived at their destination. Where did Nora go?
1. Nora arrives at her lab at the CCPD and spends the next few hours doing lab work, going back and forth between workstations, with Iris getting smothered between her cheeks every time she goes to sit down.
2. Nora stops at S.T.A.R Labs to change into her XS suit, bringing Iris along for the ride.
3. Nora gets her morning cup of coffee at C.C. Jitters and notices Iris's struggles after she spends some time taking things slow, and Nora removes whatever is moving between her cheeks to find Iris. Leading to an awkward conversation.
