Endurance Training: The Brutal Submission Pose Test
After the humiliating accident in the bathroom where I unintentionally pissed myself standing up and soaked my clothes, I was led back to the room by my owner's hand to receive some simple training to become a slave with real endurance.
"Sigh~ I was gonna let you relax, but our little slave keeps causing trouble."
"...I'm sorry, Mistress."
"It's okay~. Just get this training right and improve, alright?"
"Y-yes... yes...."
"Then I'll go grab the tools we need for the training~."
As soon as we entered the room, my owner calmed me down with her soft voice first.
It's just training, so it shouldn't be too bad.
She'd framed it as education rather than punishment, and her reaction didn't seem all that negative anyway. I desperately tried to calm myself and held onto that hope.
Until I saw what she pulled from rummaging in the drawer under the bed.
"M-Mistress...?! Why do you have these...?"
"They're for today's training, so don't worry too much~. These are nothing for our Seojin, right?"
"B-but this is...!"
A black leather binding belt, a dog collar and leash with handcuffs attached, and a huge ball gag to stuff my mouth shut.
Anyone could see these were tools for restraining a body during corporal punishment or forced service—not training. Trembling in fear that this "education" was just punishment in disguise, my owner smiled brightly and casually began fitting them onto me one by one as if it were nothing.
My hands were twisted behind my back and locked tight in the handcuffs, leather belts wrapped around my chest, stomach, and both thighs. Finally, with the gag forced into my mouth, I was reduced to a speechless slave.
"Mmph...! Nng, brrm... hngh... "
"Perfect~. You look great."
"Hooht...! Mmph, hnng... brrmm♥"
"Now I guess I should prepare the toy for the training~."
With those words, she pulled something from her pocket.
It was that same egg rotor from after lunch, when I'd been reduced to a footrest. Before I could even react—no, I couldn't speak anyway—she shoved it straight into my already-spread pussy. Then she zipped it up tight and locked it with a padlock, sealing me perfectly.
"There. All set~."
"Hngh..., mmphng... "
"Alright, shall we head to the living room now?"
Satisfied with my look, she clapped once and yanked the leash attached to my collar. My neck jerked forward, tightening around my throat, and I hurriedly shuffled after her.
Top half physically controlled by the dog collar binding my hands, bottom half controlled by signals from the pink wire running from my pussy to the remote in her hand. With my arms bound overhead, I stumbled awkwardly to the living room, my body shuddering from the occasional rotor buzz.
"Pfft, haha, this is hilarious. Hey, Seojin, take a look at this...."
"...Hooomp."
"Oh, right? You can't even see."
Hye-won, laughing at her smartphone on the sofa, went wide-eyed at the sight of me. She set the phone down, wiped the surprise from her face, and smirked with interest.
"Anyway, you look way more like a proper slave now."
"Mmph, ooomph... "
"Exactly~. Our slave needed some education, so I prepped her like this."
Seoyeon grinned and dragged me right in front of the sofa where Hye-won sat. Another of my owners, and usually the kind, gentle one—but not now, not when I was a slave in need of training, defenseless before her.
- Slap!
"Hbbrmph?!"
"Aigoo, I knew something like this would happen when you pissed yourself standing up, you bitch."
"Hooh, nng... brrmph...!"
"So what's the training for? What'd she do wrong to deserve this?"
Hye-won gave my ass a light smack, then shifted to press firmly on my lower belly while chatting with Seoyeon. Seoyeon gave a quick summary of what just happened, and Hye-won nodded, pressing even harder.
"Brrooooph?!♥"
"So she stood there pissing herself like old times and soaked her clothes because she has no endurance?"
"Yup~. So we're doing some endurance-building training this time."
"Good, perfect. Should've known your place, you vulgar bitch slave."
"Bhooh...!"
- Thwack!
"Hngk?! Mmphooong♥"
"Doesn't matter if she's my friend, but as a rights-stripped slave, she needs to do it right?"
"Hngh, brrmph... "
I didn't need her fingering my pussy that hard...!
I wanted to complain and run, but my mouth was gagged, wrists locked to the collar. All I could do was stand there and take Hye-won abusing my pussy and lower belly.
"Hee, hngh.... Mmoong...♥"
"So what's this endurance training exactly?"
"Simple. Just a basic test that's great for building endurance~."
"A test?"
Seoyeon tugged the leash, dragging me to the center of the living room. Standing there like an exhibit under Hye-won's gaze, shame and humiliation made my body tremble. Just holding this position was tough, but Seoyeon Mistress stood before me and commanded in a cold voice.
"Okay, slave. Let's start with the basic submission pose."
"Hnghoop?!"
"You've done it as a bitch in heat, so you can do it as a slave too, right? Hurry up~."
A submission pose in this situation? But as a slave, I couldn't refuse my owner's command, so I slowly squatted and spread my legs wide.
Ugh, the suit... it's squeezing so tight...
I could barely sit in a chair before, leading to this mess—there's no way I could easily fold and spread my legs fully. But staying still would make me a defiant slave deserving punishment, so I strained with all my might to bend and part them.
- Creak, squelch
"Hoohooop...! Nng, brrmph... "
"Aigoo, can't even do a proper submission pose. This gonna work?"
"Hngph?!"
"Spread 'em right, slave bitch. Don't you know what a submission pose is?"
Hye-won glared coldly, and I wrenched my half-spread legs wide apart. A truly shameful, degrading pose exposing my privates raw. At least the bodysuit covered everything so my pussy and tits weren't fully visible.
Ugh, weird. Feels like... this pose is locking me in place...
Holding the submission pose, the forcibly stretched latex bodysuit contracted, squeezing my flesh hard. It wouldn't lock me like this forever, would it...? A strange anxiety and fear washed over me, like I'd be stuck motionless eternally.
"Good girl. You obey well enough, so training should fix you right up~."
"Hngh, mmph... hmnng...!"
"But our slave lacks endurance, so maybe a little help to hold the pose."
"Mmoo...? Hnghoong?!"
Seoyeon crouched before me and undid the belt on my thighs. She extended it to bind my thighs and calves together tight. Wait, like this I can't move...!
"Mmph...!Hngh, mmoong!"
"There, now holding the pose should be no problem, right?"
"Hoohooong...!!"
"Just maintain it like this. Not hard, is it?"
Like Seoyeon Mistress said, maintaining the pose wasn't hard. No—she'd forced me into it so I couldn't break it even if I wanted to. Relax my legs even a bit or try straightening my knees, and I'd lose balance and crash to the floor.
Thinking I had to endure this brought tears pricking my eyes already.
"Hiiin...? Eeeh, ooae... "
"Perfect. Test starts now~."
"Hnng...?"
- Click!
"Hbbop?! Mmphooong♥"
Smiling, she pressed the button on the remote in her hand and set it down before me. Simultaneously, massive vibrations surged from my pussy. Shaking, I glanced down—the remote was set to max intensity. No way she expects me to endure this in this pose... right?
"Hold out just 10 minutes like this, and I'll acknowledge you as an enduring slave~."
"Hnghoooop?!"
"Our Seojin can do it. Right?"
Facing Seoyeon's brazen smile, I shuddered. Thighs and calves bound, forcing my folded legs in the submission pose was already killing me—now endure this rotor too? But an owner's command is absolute. With limbs bound and leash in her hand, physical resistance was impossible.
"Brng, hngh...!Mmphoo, oong♥"
"That's right~. Just 10 minutes like this."
"Hnghooo...!Mmphooong...♥"
And so I was semi-forced into the test: 10 minutes in the submission pose enduring the rotor.
Ugh, this hurts.... How am I supposed to last 10 minutes like this...
Forced bent-leg pose tore at my thighs and calves. I could maybe hold the pose, but the rotor inside my pussy was the problem. Max power deep inside mercilessly shook me, constantly threatening to break me.
Ugh, rotor... too intense...♡
Oddly, Seoyeon's settings made it vibrate just grazing my most sensitive inner spot. No climax, just relentlessly tormenting the edges, heating my guts cruelly. If it hit the spot, I'd cum quick and be done—but this denied release, forcing endurance. Sweat built inside the latex bodysuit, slick and rubbery over my skin.
- Vrrrrmmm…! Clink, thump!
"Heeoop...!Mmph, oooong...♥"
The lock on my pussy.... If only that wasn't there...♡
Occasional vibes hitting the spot made my hips twitch involuntarily, the padlock on my crotch zipper bouncing up to thump my clit through the latex. Dangerous. Really dangerous. At this rate, no 10 minutes—I'd cum shamefully first. Losing balance, I'd collapse like a four-legged pup flopping over, limbs splayed. Then they'd say slaves like me suit animals, add dog ears and tail. No chance to study and be human—just a pet crawling all week...♡
"Oho, our slave bitch. Shaking like a leaf but holding up pretty well?"
"Hngh, mmph... "
Hye-won rose from the sofa, circling me with keen eyes before turning to Seoyeon.
"Hey, Seoyeon. Since we're testing, mind adding a variable? Can I do something?"
"Hm~. Sure, do whatever you want, Hye-won."
"Oh, permission granted?"
A bad premonition flashed at Seoyeon's approval. When Hye-won wanted to "do something" here, it was never gentle. Trembling in fear, I looked up at her. She smiled down and—
- Crack!!
"Hbbrooooph?!!!♥"
—whipped my ass viciously with a leather whip from who-knows-where.
