Allegra the Living Bike Seat Cover (Part One)

    by: NeoPhoenixStriker Author IconMail Icon
Inez's eyes flicked from you, over to the exercise bike, then back to you. "Huh, good choice."

Your blood ran cold. "Wh-What?"

"I see you eyeing the exercise bike, Allegra. You usually complain about that method of training, so it's refreshing to hear you more eager to actively participate in it today. We'll start with that, then. Good initiative."

"W-Wait, Inez! I wasn't trying to signal that or anything, I was just looking around!" You tried to protest, but your words failed you as your titanic cousin merely bent down, snagged you, and squished you in her grip.

Inez rolled her eyes. "Alright, little cousin, I take my compliment back. Clearly you're still severely out of practice, both in terms of your body strength and your mental fortitude. This really is a necessary training session today, apparently."

While you struggled in vain, Inez strolled over to the exercise bike, approaching the well-worn seat cushion. The cushion's cover effused a miasma of sweat and stench, like the tortured fabric was permeated with the liquids of three massive giantesses...which, you supposed, it was. It was stained with the combined sweat of Inez, Sloane, and Shaye, and ripped in several parts. It had been put through hell, and now your older cousin was prepared to subject you too to the exact same indescribable hell, and there wasn't a thing you could do to stop Inez from pursuing this 'righteous mission' of 'helping you grow stronger'.

Inez then slapped you down onto the bike seat, and right before she began molding you, you shouted up to her in the brief chance you had.

"Pl-Please, Inez! Promise me this won't be too long!" You pleaded.

Your cousin looked at you with an arched eyebrow, obviously unimpressed. "The very fact you feel the need to say that, Allegra, is deeply disappointing. Has it truly been so long since our last session? I'm almost upset at how far you've backtracked the progress I dedicate so much of my time to helping you achieve. A little more gratitude wouldn't hurt you, even if, again, I know you're appreciative deep down."

You frowned. "What do you mean?"

Inez huffed. "What I mean, little cousin, is that this will only last however long you want it to, just like always. You will endure my ride, and then I'll leave you to free yourself. Unless, of course, I have some other training idea in mind for you. But if that doesn't happen, your escape will be in your own hands, like always. IF you're strong enough to pop free right away, then that's good. If not, then too bad." Inez shrugged casually. "And at least if you are too weak, you'll get some more much needed training from the rest of us in the apartment during our next rides, and we'll get to enjoy a comfy cushion."

Your eyes widened. "W-Wait, so you won't--"

"Enough stalling." Inez declared decisively, before slapping her hand onto you and squashing you flat. You let out a muffled 'oomph' of pain.

Inez then proceeded to tear off the current, extremely well-worn seat cover, and tossed it haphazardly into a nearby bin of miscellaneous supplies. The bare cushion was revealed, and Inez wasted no time in stretching, pulling, and contorting your body until you fit snuggly over top the cushion, your malleable body covering it entirely. Inez tucked your excess flesh underneath the cushion, securing it in place so you wouldn't pop free during her ride, and then positioned you so that your comically elongated face took up the bulk of the actual top surface of the cushion, your poor body shielding the cushion from the impending booty-based torment.

You winced in pain at how your little cousin manipulated your body, once again wishing you had a normal relative who actually respected your rights as a tiny, and not a merciless drill instructor giantess who trampled over your life time and again in pursuit of her ridiculously overzealous crusade to train you. You also stubbornly kept your lips sealed, definitely not wanting to endure Inez's bike ride with an open mouth.

And yet, Inez spotted your efforts instantly, and effortlessly pried your lips apart. "Open mouth, Allegra. We're training every part of you, not just some parts of you. Don't think you can get off that easy."

"Budth Inedth! Ah dond wandth to!" You cried, unable to really form coherent words with your mouth forced ajar.

Inez only eyed you curiously. "Then why didn't you resist?" She shook her head. "Seriously, Allegra, you act as if you don't have the right to resist me in these little moments, but you do. It's simply a matter of your own strength not being sufficient, and a clear indicator you either need to try harder or train harder."

Does she seriously think a tiny can stand up to a giantess? You balked, incredulously. It doesn't matter how strong a ting is, a giantess will always overpower them! Why can't she get that?

And yet your internal despair soon became engulfed by your external despair as Inez high-kicked her leg to swing it over the bike seat, then hefted herself up into a standing position, her butt hovering above you. You gulped and paled in fear as your cousin's astronomically massive ass dangled above you, while Inez herself nonchalantly typed away on the bike's control pad, adjusting the settings for her upcoming ride. Inez shimmied slightly will getting ready, her booty jiggling side to side, not even her skintight leggings fully able to contain the sheer absurd mass of her giant, perky, sculpted derriere.

Finally, Inez spoke one more time. "A two hour ride seems sufficient, Allegra. Let's begin. Don't let me down."

"Inedth, pleath waidth!" You cried, but your cousin was far past the point of caring about your 'silly objections'. Instead, she simply sat down.

You'd been sat on many, many times by Inez. Hell, you'd endured thirty minutes under her booty just this morning at breakfast. But no matter how many times her ass crushed you, it never got any easier to endure. Her booty was the largest and heaviest that you had to endure on a regular basis, and even beyond that one of the largest you'd ever seen in life to begin with, the next closest being Anneli's huge caboose. But while Anneli's was fatty and doughy, Inez's was much firmer, and as such, much more unrelenting. Getting crushed under her ass was like an entire stampede of elephants crashing atop you all at once, mercilessly squishing you until nothing remained of the woman who was Allegra, and you were left as little more than a stain.

It was worse, then, being shaped into an object like this. While being reduced to a splotch on Inez's ass (or any woman's ass) was not a walk in the park, there was some small relief in being so squished that you were just along for the ride. It took off some of the pain and pressure. Stretched out into a seat cover? There was no such thing as relief. All of your entire being was now forced to uphold Inez's ass, and her full (and not inconsiderable) weight just to begin with. There would be no rescue for you until Inez got off, and your entire body ached. Your limbs tucked under the seat cushion screamed with pain, while your face and upper body bore the full brunt of your older cousin's butt smushing down upon you.

And then there was the fact that you were on a bike seat, and not just a couch or something. Inez wasn't just going to remain still upon you, a fact that became obvious mere moments into your torment as Inez launched right into a fast-paced pedaling speed. In a rhythmic, alternating, and hellish pattern, her ass cheeks began grinding back and forth against your body, leaving you to groan in agony. Her left butt cheek would smash harder into you and smear against your face, then her right cheek down do the same a moment after. Each cheek pounded down upon you, one after the other, like her ass was trying to knead you beneath her, smashing you into submission until you were left begging for mercy.

There was also the issue of your open mouth. Surely knowing what she was doing, Inez had positioned you on the bike seat so that your face made up the center of the cover, with your mouth especially right at the fulcrum of her ass crack. As such, your lips and open mouth were forced to smush into an unwanted kiss right against your older cousin's butt crack the very second she sat down on the seat, and your nostrils also got a full treatment too. And in just mere minutes of biking, a veritable waterfall of sweat began to congeal along Inez's ass crack, soaked through her leggings, and inevitably seeped right into your mouth, causing you to gag and choke but with no way to relieve yourself of the torment. Your nostrils, meanwhile, became suffocated with the ever-increasing stench of your older cousin's sweat-laden booty. Truly, every single part of you was in hell.
