Sierra's Submission: A Merchant's Price
"Late again, I see."
There was no longer any annoyance or irritation in Sierra's eyes. Instead, she stood with her arms crossed, looking at me with a resigned gaze, as if staring at a piece of roadside trash blocking her path.
"Well then, shall we head to the same place as yesterday?"
"Wow, you're not even trying to make an excuse anymore."
Sierra gave a sarcastic, slow clap, then tightly pressed her arms against her chest to cover her breasts as she followed behind me.
"Pressing them that hard is only going to make them react, you know."
"Shut up...! I feel absolutely nothing!"
Slide.
"Hieek?!"
To punish her obvious lie, I slipped my hand right past her crossed arms, groping her breasts with my thumb and index finger. The moment my hand slid inside, I felt a tiny, pert bud twitch in response. I pinched it firmly and gave it a sharp flick, making Sierra let out a short shriek as a violent shiver ran through her entire body.
"What do you think you're do-ing...!"
Dizzied by the electric jolt of pleasure shooting up her spine, Sierra flailed her arms and slapped my hand away from her nipple. She glared at me with furious, slit-like eyes, but I merely shrugged, playing it off as a harmless joke.
"First yesterday, and now this... Why must you do such vulgar things in public?! Have you no shame?"
Look who's talking, I thought. A pervert walking around without even wearing a bra has no right to call anyone vulgar.
"Isn't it your fault, Lady Sierra, for having such an incredibly hot, fuckable chest?"
"H-Hot?! Fuckable?! Ha! The nerve... Wow...!"
Oblivious to the fact that I was just teasing her, Sierra's face flushed as red as a ripe tomato. She began fanning herself with her hand, muttering endless complaints under her breath.
"I knew you were a vulgar man, but to say something so utterly shameless to my face...!"
Though her mouth never stopped complaining, she clung tightly to my back as we ventured deeper into the dingy, filthy alleyways. It seemed she was just as terrified as she had been yesterday.
Squeeze.
Clutching my waist as she hurried to match my pace, Sierra seemed completely unaware of how tightly she was pressing herself against me. I quickened my steps, thoroughly enjoying the sensation of her hard, erect nipples rubbing against my back.
Creak.
"Welcome back..."
"Good to see you...!"
The moment we stepped into the dimly lit inn, Sierra detached herself from my back and scurried up the stairs toward our reserved room. I watched her fleeing figure with a smirk, took the key from the receptionist, and leisurely made my way upstairs.
"You took too long...!"
Sierra, who had been waiting while leaning against the wall with her arms wrapped protectively around her chest, snapped at me the moment I appeared.
"And whose fault is it for running off without the key?"
"I thought it would be unlocked!"
She shrieked back, refusing to yield even an inch. I chuckled and unlocked the door. Seeing how she never broke easily only made her all the more worth playing with.
Thud.
"By the way, why did you come out without any underwear again?"
"H-How did you know?!"
She asked, looking genuinely shocked. I sighed at her foolish question and replied in a flat tone.
"I literally just touched them outside. Did you go home like that yesterday too...?"
"No, I didn't!! It's just... when I woke up this morning... every time my clothes rubbed against them, it felt so weird...! It's all your fault!"
Clutching her chest, she trembled as she sputtered out excuses, ultimately pointing an accusing finger at me. I watched her heavy breasts bounce slightly with her movements as I slowly closed the distance between us.
"W-What is it...?"
Because of our height difference, Sierra had to look up at me. Her eyes held a flicker of fear. She was undoubtedly terrified of being tormented just like yesterday.
"Take it off."
"Ugh...!"
Despite the blunt command to strip, Sierra merely gritted her teeth in frustration and did as she was told. She unbuttoned her shirt one by one, trembling as she held the open fabric apart and glared at me.
Jiggle.
Inside the parted shirt lay a deep, heavy cleavage. It had been hidden under her robe earlier, but the thin white shirt made her stiff, erect nipples stand out prominently, practically begging for attention.
I cupped Sierra's heavy breasts from below with both hands and began to knead them slowly. Although the fabric of her shirt slightly muffled the raw sensation of her skin, the hard buds occasionally brushing against my fingers made the massage incredibly satisfying.
"Mmm... You really have a breast obsession, don't you..."
Ignoring her disgusted glare, I focused entirely on her soft flesh. Slipping my hands past the annoying shirt to get a taste of her bare skin, my fingers finally reached their destination—Sierra's bare, bouncing breasts.
"Ah..."
As the heat of my palms enveloped her breasts, Sierra's hips twitched, and she took a step back. I followed her, my hands never pausing their relentless kneading.
"Haaah..."
Backing up until she hit the wall, Sierra braced herself against it with one hand, closing her eyes to endure the sensation. I deliberately avoided her nipples, focusing solely on squeezing and shaping the soft, yielding mounds of her breasts.
"Kuh..."
Slide.
I traced the undersides of her breasts with my fingertips, slowly mapping out their shape to tease her. Every time my fingers drifted toward her dark areolas only to pull back at the last second, Sierra bit her lip and glared at me.
"Hmph... You're just clumsy... This is nothing but unpleasant..."
Having her breasts kneaded for tens of minutes seemed to have made her accustomed to it, as she tried to regain her haughty composure and mock me. In response to her feeble insult, I cupped her breasts from below like I was milking a cow, squeezing tightly and pulling them outward.
"Then let's get serious, shall we?"
I whispered softly into her ear as she leaned her head against the wall, letting out soft groans. Hearing my declaration of war, Sierra flinched, but she didn't pull away.
I led her away from the wall and sat on the edge of the bed, pulling her down onto my lap. She sat obediently, resting her back lightly against my chest, though her legs were trembling like a leaf.
"...Go ahead and try, then—eeyah!"
Squeeze.
Cupping the undersides of her breasts, I pinched her nipples between my thumbs and index fingers and pulled them taut. Admiring her breasts as they stretched into conical shapes, I twisted her nipples back and forth. Having been teased for so long, they were incredibly sensitive; Sierra shivered violently, letting out a high-pitched moan.
"Ngh... Stop pulling them...!"
Plop.
"Haaah..."
Covering her breasts, which had been toyed with like playthings, Sierra turned her head to glare at me. In response to her sharp gaze, I rested my chin on top of her head, locking her in my embrace as my hands reached for her chest once more.
"Shall we start down here today as well?"
I pulled out the vibrator I had attached to her breasts last night and brought it toward her crotch. Her thighs were clamped shut so tightly that there wasn't a single gap. I gave her plump thigh a sharp slap, forcing her to part them, and pressed the vibrator against her.
"Ngh...!"
Her thick, fleshy thighs trembled. Savoring the soft skin with my fingers, I slipped the vibrator inside her white panties beneath her brown skirt and immediately cranked the vibration to the maximum setting.
Bzzzzzz.
With the vibrator held securely against her slit by her panty straps, I wrapped my arms around her again. My fingers crept back up to her breasts, teasing them. Sierra shivered at the ticklish touch, but she merely hung her head and avoided my gaze, offering no real resistance.
"Your breasts are absolutely beautiful, Sierra."
"Save your... sweet talk..."
Flick, flick. As I flicked her nipples with my index finger while whispering praises, Sierra's voice trailed off, her hips twitching from the intense stimulation.
"You're so obsessed with my nipples...!"
Even while trembling from the pleasure, she still managed to complain. I sped up my fingers, deliberately tormenting her nipples. As she tried to squirm out of my embrace, I held her tight and kept flicking.
"Mmmgh..."
Having had her nipples tormented all day yesterday, her sensitivity had skyrocketed. Just touching them made her hips arch in ecstasy. Her already sensitive body had become even more responsive from the constant stimulation.
"Why... why does my body react like this whenever you touch me...?"
She bit her lip in frustration and shook her head, but as my fingers continued their relentless flicking, her back finally arched, and she rested her head against my shoulder.
"Does it feel good?"
"I don't know... Stop teasing me, please...!"
She rubbed her head against my shoulder like a whining child, her hips shuddering. Finding her adorable, I stopped my fingers, wrapped my arms around her waist, and showered her cheeks with kisses.
"Stop it...!"
She thrashed her head like a feisty cat, her hair slapping against my cheek. I pulled my lips away and stared at her hungrily. Sierra had her eyes squeezed shut, desperately trying to endure the vibrations at her crotch, her entire body trembling with hyper-sensitivity.
"Haaah... haaah... haaah..."
"It hasn't even been an hour yet. What are you going to do if you're already exhausted?"
"An hour...? Liar..."
She whined like a child. Have I been too easy on her? Seeing her go limp, I slipped my arms under her armpits and thighs, cupping her breasts as I lifted her up.
"Huh...?"
Bzzzz.
Sierra, who had been enduring the vibrations with her eyes closed, peeked open and looked up at me. Ignoring her gaze, I carried her over and tossed her onto the specialized chair I had eyed on our first day.
"What are you doing? What is this?!"
Her buttocks hit the wooden seat with a dull thud. Sierra flailed her limbs, trying to sit up, but I forced her legs apart, fitting them into the restraints of the spreading chair, and locked them in place. The receptionist had told me the keys were in the drawer, so I didn't hesitate.
Click. Click.
As her legs were secured and the locks clicked shut, Sierra's eyes filled with despair. Her parted lips, chattering teeth, and frantic, wandering eyes betrayed her sheer panic.
"What is this...? Let me go. This is a joke, right?"
"Everything up until now was a joke. I don't think you fully grasp the weight of our contract, Sierra."
If yesterday was about easing her in with a gentle touch, today was the day to turn up the heat. My heart fluttered with anticipation at the thought of replacing her naive, carefree attitude with absolute dread.
"I'm going to teach you exactly what it means to surrender your body for fifteen days."
"Ngh...!"
With her limbs bound, Sierra could only shake her head in denial as I grabbed her bouncing breasts. I kneaded the soft flesh, rolling it between my fingers, before giving her stiff nipples a sharp, painful pinch.
"Mmmgh... haah..."
I savored her pained, grimacing face before letting go. Watching her nipples quiver on her bouncing breasts, I rummaged through the drawer next to the chair. Since this room was designed for training slaves, it was stocked with various toys. I searched for something useful and finally pulled out a perfect tool.
"Now, try to endure this."
"Hieek?!"
I pulled out a soft, feathery brush and dabbed it against her nipple. As the tip twitched, I began to tickle it gently, brushing over her sensitive bud as if dusting a delicate ornament.
"Ahhhg!!! Ah, hieek!"
Unable to close her mouth from the unexpected sensation, a thin thread of drool escaped her lips. Her head thrashed in sync with the brush's tickling strokes. With the intense focus of a master artist painting the final stroke on a masterpiece, I poured all my effort into teasing her trembling nipples.
Her breasts, already hyper-sensitive from last night, were completely defenseless against the brush. Thrilled by her reactions, which delighted both my eyes and ears, I kept going, alternating between her left and right nipples.
"Ahhh, haaa...! Mmm, nnngh...!"
Sierra, who usually had so much to say, could no longer form coherent sentences. I glanced at the clock on the wall; over five hours had already flown by.
Bzzzz.
"Ngh, haah...! Hieee!"
Squirt.
A stream of sweet juices squirted from her wide-open crotch, completely soaking her panties. I pulled aside the drenched fabric, which could no longer even be called underwear, revealing her swollen, twitching slit as it greedily pulsed and wept wetness.
"My, my..."
"Haaah... stop it..."
Bound hand and foot, Sierra's face was stained with dried tears from the overwhelming pleasure. I stroked her cheek with the back of my hand and finally pulled out the vibrator that had been relentlessly tormenting her core.
"Haaah..."
Once the torturous vibration stopped, Sierra leaned her head back with a look of relief, panting heavily to catch her breath. I took the wet, glistening vibrator and pressed it directly against her nipple, which had been rendered raw and sensitive by the brush.
"Ahhhg!!!"
Just a light touch made her arch her neck and scream. She looked breathtakingly beautiful. Her sweat-slicked hair clung to her flushed cheeks, her brown eyes shook with panic, and her red tongue trembled in sync with the vibrator's hum. I wanted nothing more than to smash my lips against hers and suck her dry.
Fueled by a sudden surge of sadism, I pressed the vibrator harder against her nipple. Her breast deformed under the pressure, shaking violently from the vibrations.
"The night is still young. What am I going to do with you if you're already like this?"
"No more... please, stop...!"
She squeezed her eyes shut and sobbed, begging me to stop. I gently stroked her cheek and asked, "Are you refusing my touch?"
The crests of the contract glow faintly in response to the word "refusal."
At the word "refusal," the crests engraved on Sierra's and my hands glowed faintly. Her current words and actions were a direct violation of our contract. Unlike her usual tsundere complaints, the glowing mark proved that she was genuinely wishing to reject me in this moment.
"Ngh... haaa..."
At my question, Sierra slowly opened her eyes, bit her lip, and shook her head. Through her half-open lids, her trembling eyes seemed filled with nothing but despair.
"I'm going to make sure you get your money's worth today, so look forward to it."
"Nnngh..."
Thud.
Sierra finally let her head fall back against the headrest. Looking at her tightly closed eyes and limp limbs, I could tell she was deeply regretting her choices.
"I'll make sure to turn you into a woman who feels pleasure more intensely than anyone else. Look forward to it."
"Sob..."
Ah, she was crying.
I spent the rest of the day tormenting her nipples as she wept. Thanks to my dedicated efforts, by the time our second day of the contract ended, Sierra's breasts had been trained to the point where even a light tap of a fingernail would make her shudder and moan.
