Establishing a Routine (1 of 2) Tiny Brother VS Big Sister chapter 27 by copier · original author: rpcity

(I guess I wrote too much....this had to be split into two parts)

You felt a gentle sway as your “trainer” walked through her apartment before an unexpected drop. You brace yourself for the worst, but feel a relatively light pressure covering your small form.

Kate felt like it had been a long day and was ready for a good night’s rest. But when she plopped down on her soft mattress, she frowned.

“This is far too much padding to make for effective training, don’t you think Allen?” she asked, shifting her hips across the bed.

You, of course, were in no position to respond.

“Well I’m not about to sleep on the floor for the next month for the sake of your training. I have to take care of myself too afterall…” she paused in thought for a moment before her eyes lit up brightly.

“Oh! Fortunately I know a great way we can continue enhancing your pain tolerance while I sleep!” she exclaimed, leaping off the bed and roughly peeling you from her backside.

She gives you no time to reform or recover as she begins manipulating your flat body. She stretches your torso and each of your limbs, pulling a pained scream from your flat lungs.

Kate simply smiles. “See? I’m going to increase your tolerance to all orts of pain, not just the crushing you deal with most often,” she says happily, admiring her handiwork. She tied your hands and feet to a couple of elastic straps and grinned broadly.

“There! All done!”

She held you up to a mirror and, if you had been able to see yourself, you would see that she had formed you into a thin thong, with your body perfectly positioned at the rear. Even without being able to see the full picture, your body shivered in fear for what was to come.

Kate smiled as she casually deposited you on her nightstand. She’d need both hands to properly position you. You heard the ruffling of clothing and struggled to free yourself, but didn’t have the strength. She quickly removed her shorts and panties and gripped the straps you were tied to, her smile growing broader at the sight of the panicked look on your face.

The personal trainer was about to get a whole lot more personal. She put her feet through the loops your body made with the straps and pulled you up slowly. You squirmed and struggled as you saw her bare ass drawing closer, but again you found yourself unable to break free.

Kate moaned softly as she felt your soft body pull deep between her full cheeks. You kicked and screamed for all you were worth, but it just amounted to some muffled buzzing to your trainer, who let out a chuckle. She caressed her cheek gently, bouncing her flesh over your body, before pulling up her pajama bottoms, engulfing you in complete darkness.

She stretched, yawned, and finally plopped back into bed. She flexed her muscles over you, squeezing and pressing you from all angles and smiled again as she felt your screams of pain.

“Mmm, much better,” she said quietly, before raising her voice enough for you to hear, “I told you there was more than one method for this training Allen.”

Kate smiled before rolling over and quickly falling asleep. Unfortunately for you, she was an active sleeper. Her legs were constantly moving and she tossed from side to side in her sleep. Every movement of her lower body meant your stretched form was pulled in a new direction, causing you all sorts of pain all across your body. In places you hadn’t felt pain before. Eventually, your throbbing body had endured more than your mind could tolerate and you passed out into a restless sleep.

Kate woke refreshed, virtually leaping out of bed before stretching and changing into her workout gear for the day. She didn’t feel much movement from you, so she decided you needed a wakeup call. She pulled out the waistband of her running shorts and peered over her shoulder. You were buried too deep between her cheeks for her to see even a glimpse of you, but she knew you were there. She let the waistband snap closed. You stirred slightly at the noise of the fabric against her skin.

She gripped each cheek with a hand and slapped and jiggled her ass, sending you into a whirlwind of moving, pounding flesh.

“Wake up Allen! It’s time for day two of your training!” she sang happily.

Despite your sleep, your body was still exhausted and felt much less chipper than she seemed. You tried to plead for your release, but it amounted to more pleasant buzzing for your trainer.

“A little preview of our day Allen. I’ve found training works better with a routine, so today will give you an idea of what your daily routine will look like this month. I’m going to get started on a run, and you’re going to stay right there. When we get back, we’ll get cleaned up, eat a healthy breakfast, and head to the gym!” she said happily.

Kate didn’t wait for a response from her client, but started to stretch before stepping out her door. Her stretches alone put immense pressure on your body. You weren’t used to having this much pressure put on your body in so many different ways, and the pain hit you immediately.

Your trainer ran at a steady, rapid pace. With each stride of her muscular legs, you were pulled a bit deeper between her cheeks. While it spared you some of the pounding from her fleshy ass, the deeper you went, the more the elastic straps pulled on your limbs. You were trading one pain for another.

The run was mind numbing, but the sweat that built up between Kate’s cheeks wouldn’t let your mind fade into sleep. You were awake and conscious, if not alert, for every painful, unpleasant step she took.

It was a relief when you felt her strides slow to a walk, you realized her run was nearing its completion. Confirming your theory, you felt light flood into your “training center” for the first time and absent mindedly let out a sigh of relief. Apparently, Kate – the ever present trainer – felt it, and chuckled.

“Don’t be too happy my run is over Allen. Remember, your training is going to be consistent. No breaks. It will continue in my shower,” she said sternly as she plucked your tattered body from between her cheeks and pulled the makeshift thong down her legs. To your amazement, she removed the bonds that held you to the elastic straps with ease and kept her eyes locked on you as she proceeded to get undressed.

If you were in your normal state, your jaw would have dropped as the view of your gorgeous trainer undressing unfolded in front of you. She glistened with sweat, but it complimented her athletic body perfectly. Her round, full breasts glowed and her flat stomach shone. Your trainer, of course, noticed your admiration, but let it pass without comment.

She gripped you in a tight fist and walked to her shower. It took just a moment to adjust the temperature to the correct level. Without warning, she released you and you fell what seemed like miles before crashing to the floor of the shower with a pained moan. The cascading water pounded at your body incessantly, with the only breaks coming as Kate’s enormous body shielded you from the stream.

As she moved, you quickly realized she wasn’t paying much attention to you as she washed her hair. That led to you being crushed beneath her feet several times. You did your best to stay clear and aware, but your battered form and the wet shower floor didn’t make it easy to stay active. You were pressed beneath her heels several times, met and stuck to her sole for several minutes, and when she found you with her toes she gripped you tightly.

Finally, her hair was clean and she bent over to pick you up again.

“You need to clean up too Allen, so why don’t we do this together?” she said with a smirk. You had no opportunity to question her, and it likely wouldn’t have mattered if you had, before she crushed you in her fist and applied a generous amount of body wash to you before letting it pour over her own body.

She pressed your body all over her wet, nude, athletic form. You flowed around and under her breasts, across her flat stomach, and up and down her thick thighs. Finally, she returned you to her ass. She used you to thoroughly clean the outside of and between her cheeks as well as her crotch. She was clearly enjoying this. As far as pain tolerance went, you really didn’t mind this part of the training. You had certainly already endured significantly worse.

Finally, Kate felt she was clean enough and turned off the shower. She wrapped herself with a towel and quickly dried you as well. She smiled at you as she gently placed you down on the dresser, giving you a chance to finally recover and reform as she dressed in clean clothes for the day. After the beating you took, you weren’t completely back to normal by the time she was dressed, but you were surprised that Kate gently picked you up and lifted you to the breakfast table instead of crushing you immediately.
