Work Text:
Uni jolted awake to the sound of a high pitched whistling. A kettle, sitting far closer to Uni’s ear than made any sense. Had she fallen asleep in the kitchen by accident? Uni could hear some other less prominent sounds. Bubbling, sizzling… but none of the clattering or steady chopping sounds that Uni would expect if someone were cooking.
Her body felt heavy, but trying to go back to sleep in such a state was impossible. Too many strange noises, too many questions about what could possibly be going on around her.
Uni opened her eyes as she tried to sit up. Immediately, she was met with resistance, her body refusing to lift up. The ceiling above her was unfamiliar, the room only dimly lit. Uni had no idea where she was… but it felt like she was strapped down on a table. Naked. Her wrists and ankles wrapped in thick ropes, on top of the leather straps holding her legs in place, and her arms above her head.
“O-Onee-chan?” Uni asked nervously, looking from side to side as far as her restraints would allow, but finding nothing but dark concrete walls. Uni tried desperately to remember what she had last been doing, how she could possibly have ended up in such a state.
Noire hadn’t been there… Uni was starting to recall. She had left Uni in Leanbox for the weekend, asking Vert to watch her while she was gone. After that, Uni was struggling to remember anything.
“Vert? Anyone?” Uni called out, louder this time. She wasn’t sure she wanted to meet whoever had taken her like this, though.
The whistling sound stopped, as Uni heard water sloshing about. She didn’t dare so much as breathe, waiting for her captor to make themselves known.
“Ah, perfect timing, Uni-chan~”
Uni’s breath hitched. That was Vert’s voice… Was this all some sort of elaborate joke? Was it all Neptune’s fault somehow?
“I’m glad to see you’re awake,” Vert continued, though Uni still couldn’t see her even when she craned her neck, “I’ve got the water all nice and boiled for you—Ah! We’re going to have so much fun today!”
“Oh…? Are we having tea or—” Uni started cautiously, before she realized she was getting caught up in Vert’s weirdness, “No, forget about that! Why am I naked, Vert? Why can’t I move?”
Uni didn’t like the way Vert was acting one bit. To completely ignore Uni’s current state… The only reason Uni could think of why Vert wouldn’t be surprised was if she had done it herself.
“Of course you can’t move, Uni-chan,” Vert said, walking towards the table with light footsteps, leaning over so Uni could see her smiling face clearly, “If you ran away, I wouldn’t have anyone to play with~”
Vert’s expression was entirely serene… but Uni didn’t calm down one bit. She tugged harder against the leather straps holding down her arms and legs, but there wasn’t any give at all.
“V-Vert, please,” Uni begged, hardly able to bear meeting Vert’s gaze, “you’re scaring me…”
“Hehe, you look so cute like that, Uni-chan,” Vert laughed, gently brushing Uni’s stomach with her fingertips, “I’ve always wanted a little sister… but Chika never allowed it. She wanted to try to be that girl once, a plaything I could tease and torment to my heart’s content—”
Vert leaned down, accentuating her words with several light kisses across Uni’s chest, tracing out the gentle curves of her breasts. Uni’s body struggled against her restraints, making anxious noises of protest… but Vert only stopped when she felt like stopping, moving up to look Uni face to face once more.
“She tried so very hard… Chika really did. But pain avoidance is such a base instinct, so hard to fight. She tried so desperately to please me, only to give up just as quickly. But it convinced her I couldn’t be trusted with a little sister of my very own. Does that sound fair to you, Uni-chan?”
It all sounded so horrible. Uni didn’t know what Vert did to Chika exactly… but it sounded like it had started a lot like this. Trapped, confused, afraid of Vert’s intentions. If Chika was so insistent that a girl Uni’s age shouldn’t be in Vert’s care, Uni could only imagine how justified she was.
Vert wouldn’t let it stay in her imagination for long though. She had Uni at her mercy, and Uni didn’t think Vert had much mercy to spare. Not with how she was acting right now.
“Just let me go, Vert. Please!” Uni pleaded, growing more and more desperate as thoughts of what Vert might do to her filled Uni’s mind, “When Onee-chan finds out—”
Uni felt something smack right between her legs—heard it, too—as Vert brought a hand down on her. It stung, but Uni cried out mostly from the shock alone, unable to pick back up on what she had been trying to say.
“Noire isn’t here right now, Uni-chan,” Vert told her, “She left you in my care, and that means I’m ‘Onee-chan’ now. Understand, little sister?”
Uni wanted her sister back all the more now. She didn’t know how long Noire planned to be gone, how long Vert had waited after they were alone. But Uni didn’t expect Noire could be getting back any time soon, even if she had any reason to suspect anything untoward.
“Shh, shh, it’s okay, don’t cry, Uni-chan,” Vert said softly, taking a step back to grab something Uni couldn’t see, “You need to save some of those tears for when it really starts to hurt~”
Something hot pressed into Uni’s abdomen, forcing a sharp scream from the girl’s lips. It burned into her skin, two lines of fire crossing in the center in the shape of an X. No, Uni realized—feeling the details along every inch of searing flesh—it wasn’t just an X…
“There we are,” Vert sighed with contentment, putting the branding iron off to the side once more, “The Leanbox logo looks so good on you, Uni-chan! Now it really feels like I own your body completely~”
Uni could only whimper softly in pain, trying to get the fresh pain out of her mind, though just the air brushing against it alone was unbearable. Uni felt Vert’s fingers teasing at her skin, tracing out the shape now burned into her.
“Ah… I just can’t take waiting any longer!” Vert said excitedly, moving back up along the table to take Uni’s lips with her own.
Vert wasn’t a bad kisser exactly. Uni just couldn’t stand Vert’s tongue in her mouth, Vert’s hand on her chest. Vert wanted to claim every inch of Uni’s body, and unless Uni figured out a miraculous escape, she was powerless to resist.
Vert pulled away from Uni’s lips, once she had her fill for now. She stared hungrily into Uni’s eyes, still pinching and rubbing at her nipple, disturbing any attempt for Uni to steady her breathing.
“I think you’re ready now, Uni-chan,” Vert giggled, as if she had uncovered a dirty secret, “So would you rather try the water or the oil first?”
Uni was struggling to keep her thoughts straight, and so at first Vert’s words sounded like total nonsense. But then she remembered waking up here. The shriek of hot steam, the splattering of boiling oil… Uni winced, imagining all sorts of terrible things Vert might need those for. And Vert was implying Uni would find out both firsthand, before long.
“No… Vert, no, please!” Uni protested, because it would be insane to agree, not because she had any hope Vert would listen, “I can’t… please don’t make me—”
“You’ve got to choose~” Vert practically sang out, “This sort of play can be really dangerous, Uni-chan. If you mess up all the plans I have, I’ll need to improvise… and then who knows what sort of damage I’ll cause?”
Vert smiled at the thought, filling Uni with fear. There was still something inside Vert, that was drawing a line somewhere. A step too far for even Vert to justify to herself. But it seemed refusing her twisted desires was a yet greater offense in her mind. If Uni didn’t choose… whatever Vert ended up choosing for her would somehow be even worse.
“W-Water,” Uni stammered out between quiet tears, “Give me… give me the water.”
Vert’s palm ran a few more lazy circles against Uni’s chest, before lifting up. Vert clapped her hands excitedly, before turning back to grab the kettle from earlier.
“Mmm… It’s a nice choice, Uni-chan,” Vert commented absently, as Uni listened to the water sloshing around inside the kettle, sounding so very full, “Boiling water burns the skin in such an exquisite way, so agonizing if not tended to immediately~”
Uni felt her body trying to unconsciously lean away from where Very held the kettle over her, but she knew it was no use. Uni was completely defenseless, and Vert sounded so very eager to empty the entire kettle. Uni shut her eyes, trying not to let the anticipation overwhelm her.
“So where should I put it, Uni-chan?” Vert asked, as if she hadn’t thought about all the worst places for far longer than Uni, “Your chest, maybe? Your nipples would look so cute, sizzling up hopelessly. And your chest is so flat that I could pour as slowly as I wanted, knowing how long the water will take to slide down off your skin~”
Uni began to hyperventilate, Vert’s descriptions making everything feel so much more real, imminent. There was only a single word standing between Uni, and all the suffering Vert promised. Or Uni could say something else—her stomach, her arms—and accept the untold pain that would follow. But she had to say something. Had to push herself in, or else Vert would make Uni pay for it.
“I promise I’ll be careful, if you want it on your face,” Vert continued, when Uni didn’t give an immediate response. It was hard to tell if Vert was threatening Uni, or begging her to try it.
“C-Chest! Please, Vert, not on my face…” Uni blurted out an answer in complete panic. There was no thought process, just blindly grabbing for the only other place Vert had suggested. Maybe that had been Vert’s intention from the start. But there was nothing Uni could do to stop Vert from acting as she pleased anyway.
There were no immediate words of praise. No cooing over the pain Uni had chosen for herself. Just a few drops of water, spilling haphazardly from out of the spout.
Uni gasped in pain, as those first droplets landed between her breasts. With so little water, it didn’t take long to cool, but not before that heat stained stray patches of Uni’s skin with sizzling pain.
“You liked that, Uni-chan? Your skin looks so much more colorful now,” Vert said, feeling no need to rush through Uni’s torment, “You’ve always been so pale… I think red will suit you much better. But I’ll have to cover you thoroughly, or else your chest will look all splotchy~”
Vert’s words were their own sort of suffering, but none of it could compare to when Vert finally gave her first pour in earnest, tilting the kettle gently over Uni’s nipple, letting the boiling water flow out freely. It was most intense right on the tip of her nipple, wrapped from all sides in scalding water, but even as the water rolled down Uni’s sides and onto the table beneath her, it had lost so little of its heat. Burning every inch of skin the water ran across, Vert’s pour was so very slow but so very steady.
Uni’s nipple was a raw, burning nerve, sticking out of her chest as taking the flow without end. Uni thrashed against her binds, but she couldn’t so much as tilt her nipple away from the worst of it. Just when Uni felt certain the ceaseless assault would wear away at her nipple completely, leaving nothing but raw skin behind, Vert switched sides.
The second time wasn’t like the first. Water didn’t stay put, once poured, and burns would flare with pain long after the heat was gone. Uni’s chest was already a ruined mess, Vert was merely evening out the damage a bit more, focusing down on Uni’s other nipple until it caused her just as much agony.
“You’re doing so good, Uni-chan,” Vert told her, quietly taking in the constant cries of pain that Uni let out, despite how strained her voice was at this point, “I’m nearly out of water now… so very close~”
It wasn’t the first time Vert had said those same exact words. Uni was in no state to guess how much water was still left, and Vert had no reason to tell the truth. Vert’s hand was too steady, too disciplined, for it to end so quickly. But Uni clung to her words anyway. She had to believe it might almost be over now—or at least, Vert would be done doing this to Uni.
Uni could only try to lose herself as best she could manage. Her body could only tell her how much pain she was in, how much the water burned against her already terribly damaged skin. Even her voice wasn’t her own, helpless but to scream and scream and reward Vert for her efforts.
Then the water stopped. Vert hadn’t stopped pouring, there simply wasn’t any more coming out. Uni hardly noticed, aside from a vague acknowledgement she could no longer feel the water running along her skin. All the pain was still there, every inch of flesh along her chest protested their exposure to the air just as much. In fact, it hurt in an entirely new way, that Uni hadn’t been ready to take so suddenly.
Vert giggled at the pained gasps Uni gave off, before she started screaming again, even without Vert doing anything at all to her now.
“Just bear it a little longer for me, okay Uni-chan?” Vert asked, as if she only needed a small favor from the girl writhing in pain under her attentions, “Oh, wait. I nearly forgot~”
Vert turned the kettle straight sideways, the last dribbles of water spilling out all at once, splashing in between Uni’s breasts. Uni would’ve hardly felt the small difference, except that Vert waited long enough that Uni had gotten used to the air, and the water made her abused skin flare up in an entirely different way, if an all too familiar one.
Every time Uni thought she could finally push through the pain, to steady her breath for even a moment, Vert would tease her chest in some new and agonizing manner. Blowing on her raw skin, squeezing her abused breasts, licking her ruined nipples—biting them even, when all Uni’s other reactions grew too dull for her.
Uni now found herself longing for the feeling of Vert’s tongue on her chest, from before all the pain had started. Instead she could only feel the twisted echoes of that sensation, distorted by layers of burnt skin, any hint of pleasure buried under unending pain. But the pain was everywhere, Vert’s mouth could only focus on one singular place at a time. The pain was worse, in some ways, but it felt more real, something her hopelessly broken nervous system could still understand. It gave Uni something to hold onto, however much it hurt.
Uni’s screams began to slow, smaller gasps of pain matching the rhythm of Vert’s lips and tongue. Every cruel nibble made her breath hitch, Vert’s teeth too sharp and uncaring. Or maybe Vert cared too much, but about making sure Uni suffered as much as possible.
After several painful breaths, Uni noticed that Vert had stopped. Cautiously, she opened her eyes, finding Vert watching her with a smile, taking in Uni’s expression, all curled up in pain.
“You look so cute like that, Uni-chan~” Vert cheered, patting Uni lightly yet all so awfully on the chest.
“I-It hurts, Vert…” Uni whined, her voice weak, her will shattered, “I—”
Vert put a finger over Uni’s lips, silencing her.
“Relax, Uni-chan, that’s a good sign,” Vert said, in some cruel mockery of reassurance, “That means we still have time—if we act quickly—before more permanent damage starts to set in~”
Uni’s eyes widened, almost forgetting Vert might have any concerns like that to begin with. Maybe it would make it harder to torment Uni again? Uni didn’t even want to think about such a possibility.
“Vert, please,” Uni begged her, this time with some small amount of hope Vert might listen, “You got what you wanted. So please, help me…”
Uni felt more tears start to flow. The pain was unbearable now, but the idea that Vert’s treatment might scar her for the rest of her life… that would never go away.
“Oh, my, my… So eager now,” Vert giggled, “Don’t worry, Uni-chan. I came well prepared.”
Uni watched in stunned silence as Vert unstrapped her legs, and then her arms. But the surprise was nothing compared to what came next.
“Now take a deep breath in for me,” Vert said—before she unceremoniously pushed Uni off one side of the table.
A tank of water waited below, impossible to see from Uni’s limited vantage point strapped to the table. It was just large enough to fit Uni’s body completely, maybe a bit larger. Uni didn’t think that was any coincidence.
The water was freezing, filling Uni with shock for a moment too long—a grate closing down right in front of her, trapping Uni beneath the waterline. Her thoughts jumped immediately to air—luckily having obeyed Vert’s last minute order without question. But Uni didn’t know how long she could hold her breath. Not really. Not when she had no other option but to keep holding it.
Her chest did calm down a bit, not screaming nearly so loudly as the icy cold water ran over it. The rest of her body was miserable, the cold biting at her skin. But Uni would almost find it pleasant, if it weren’t for her breath, ever slipping away, her chest burning in an entirely different way as her lungs cried desperately for air.
After much too long, when Uni felt she couldn’t hold her breath another second more, a pair of hands dipped back into the water, opening up the grate to pull Uni’s head above water.
“Breathe, Uni-chan.”
Uni obeyed. Her body would allow nothing less, clawing desperately for air, gasping in painful relief.
“You were down there for three minutes,” Vert told her, making no attempt to hide the fact she had been gleefully counting every second, “But for burns this serious, they need to be fully immersed for ten. Do you understand, Uni-chan?”
Uni was in pain. Her brain was starved for oxygen. But she understood enough. She was going back down again.
“Good,” Vert smiled, as Uni gave her a pathetic nod, “Just know that I’m not pulling you up again until time is up…”
Vert leaned over the edge of the water tank, pressing a sloppy kiss into Uni’s lips. Uni was far too broken and defeated to care. Vert’s tongue felt far better in her mouth than it had licking the burns on her chest. Uni just wished she couldn’t taste how eager Vert was, how aroused the thought of pushing Uni under again made her.
“Breathe in, Uni-chan~”
Uni took in as much air as she could manage, before plunging into the frigid waters once more. Vert shut her in tight once more, leaving Uni alone with nothing but her thoughts.
She hadn’t even had time to muster any outrage over her absurd treatment now. Vert had—thankfully—avoided Uni’s face the whole time, as she tormented Uni’s chest. There was no reason Uni needed to be down here, head beneath the surface.
There was no reason for anything else Vert did to Uni though either. The whole point was to see her suffering—why would any of that change just because Uni was in need of immediate treatment? Uni just hadn’t been thinking straight, to have expected any different from Vert.
It had been hard to think straight this whole time, between the disorientation and the pain and now the air in her lungs slowly slipping away. Seven minutes was a long time. Uni didn’t know if it was something a normal person was capable of, staying down that long. She was in good shape, but she had never tried to hold her breath nearly this long before.
Uni suspected that Vert didn’t want her to last to the end. It was the last concrete thought she had left, circling back to it again and again, as Uni wondered how long she had been down here. She knew that it wasn’t as long as she would want it to be. Her hands pressed against the metal grating, fingers wrapping into the openings. Uni wasn’t going to last.
Uni awoke to a dimly familiar sound. Sizzling, bubbling, cracking.
Her lungs burned something awful, her breathing difficult. She was freezing. She was naked. She was strapped to the table again.
Uni’s eyes shot open. Already, she was certain this was all happening. That the memories coming back weren’t just some terrible, but now fading dream. No, Vert did that to her. Vert was going to continue to do things to her.
Beside her, the pot of oil continued to boil.
“Uni-chan~” Vert cried with joy, sending all sorts of terrors through Uni, “You did so well! You almost made it the entire way through before passing out, I was really amazed…”
Uni kept quiet. It was Vert’s turn to talk, to tell Uni what would be done to her next. Then it would be Uni’s turn to meekly nod and accept it.
“Hehe, anyway, the oil had gone a bit cold, but don’t worry!” Vert continued, with her now familiar enthusiasm, “I’ve got it nice and piping hot for you now.”
Uni shifted uncomfortably in her binds. Her chest still burned something awful. Whatever treatment Vert might deem necessary, she wouldn’t focus on making sure it would hurt less after it was all through. Quite the opposite, if anything.
The oil loomed heavy in her thoughts. It had hardly been a choice back then. Water or oil. Uni had no way to know what it would really feel like, at the start. Now she was left with just the oil, and she had a much better idea how agonizing it would be.
“Ah… you’re thinking about it, aren’t you, Uni-chan?” Vert teased her, “We’ll get to it soon enough, I promise. It really does have a completely different feel to it… But first, I need to know where you want it~”
Uni steeled herself. She wouldn’t make the same mistake last time. She would think. She would ignore the pressure to decide immediately. She would choose the least painful thing she could think of—even if there were no good options.
“Could I…” Uni started, after a brief silence, “Could you do my feet?”
It sounded safe. Maybe it wasn’t. Uni knew it would definitely hurt, but she could only hope she wasn’t still underestimating it.
“Ooo… Uni-chan’s feet~” Vert squealed, running to the far end of the table to take a closer look, “They are pretty cute, aren’t they? They totally make you want to fry them up and eat them!”
Vert rubbed Uni’s feet in her hands, feeling how small and delicate they were. Uni winced when she realized how sensitive the soles of her feet felt. She had no doubt Vert would make sure they were absolutely slathered in oil… but it was too late to change her mind now, with how excited Vert was acting.
“Your toes are so adorable too,” Vert praised her, moving her face in close, taking Uni’s big toe into her mouth and sucking deeply. It felt funny, but Uni knew it wouldn’t be nearly so pleasant when Vert did the same thing again afterwards.
Vert’s teasing didn’t end so easily. When she released Uni’s toe, it was only to move onto the next, working her way down in order. Her tongue slipped deep between Uni’s toes, tasting every tucked away little corner. Uni would complain it was too dirty there… except she had just been given the most horrifying bath of her entire life. Instead, Uni simply let Vert do as she pleased, switching from her left foot to her right foot halfway through, before finally releasing Uni’s last, littlest toe with a noisy pop.
“Ah…” Vert sighed, giving Uni’s foot one last long lick along the bottom, “Uni-chan’s toes are just delicious—but they’ll taste so much better with a little oil~”
There was no more stalling. Vert took the oil off the heat, stirring it around with something Uni eventually recognized as a small ladle, once she could see it properly.
“Now, your feet are so tiny and cute,” Vert told Uni, her tone casual in its warning, “So don’t be surprised if I spill a little further up your legs! But I’ll try to pay your feet all the attention they deserve, Uni-chan.”
Uni nodded, not too surprised. If she had tried to pick something too small—a finger, her heel—Vert would’ve similarly expanded her reach, if not simply ignored Uni entirely for not abiding to the spirit of the question. If it was her feet and legs, Uni could still bear with that. She had no other choice but to do so.
“Alright, here it comes, Uni-chan!”
There was no build up this time, no teasing start. Vert scooped up a ladle-full of oil, and poured it over Uni’s foot. She poured along the tips of Uni’s toes, making sure the oil was shared by all of them, and that it ran down both sides of her foot.
It felt like Uni had simply stuck her foot into a raging fire. Heat swallowed up all those earlier sensations of licking and sucking, pain filling Uni once more. Tears came all too easily, but that was nothing new either.
Vert took her time between each scoop, watching the oil drip down from top to bottom, pooling around Uni’s heels. Blisters formed on the undersides of Uni’s toes and feet, though not even the slightest patch of skin was far from Vert’s attention. The oil was too hot for Vert to consider touching—she only liked to see Uni suffer as such—but she could use the back of the ladle to rub the oil deeper into Uni’s skin.
Uni thrashed and fought against her restraints, helpless to move her feet away. She watched them crack and burn, her view so much clearer now than Uni had seen of her chest. She could see just how happy Vert looked, taking another sizable helping of oil to torment Uni’s feet with.
Uni shut her eyes tight after that, her cries loud but pitiful. She could still feel the oil, feel the heat. She could still feel Vert start to cheat up her legs, just as promised. But Uni couldn’t bear to watch it at the same time.
“Hehe, your face is just too cute like that, Uni-chan,” Vert told her, though Uni refused to open her eyes in acknowledgement, “I’m a bit sad I went through all that oil so quickly—but I know just where I should put the rest of it~”
Vert’s words were concerning. Uni would be lying to say otherwise. But there was also nothing she could do to change things now. Seeing what Vert was doing wouldn’t help. Uni waited for whatever Vert was planning next.
“Aww… it’s smiling at me,” Vert cooed, letting the anticipation build, “Aren’t you such a cutie, begging to taste a little oil—yes, such an adorable little pussy~”
Uni’s eyes shot open, but all she could do was watch the oil fall, before screaming out in pain. The oil was so hot. Her skin was so sensitive. Vert just kept layering it on. Uni felt her outer lips burn, absolutely drenched in pain. She felt the hot ladle press against her lower lips, parting them slightly.
“No, no!” Uni screamed out, somehow managing intelligible words, her panic gripping her so fully.
Vert didn’t listen, of course, gently tilting back the ladle. Uni felt her insides start to burn. Not much made it very far, but even the tiniest trickle slipping inside her pussy was complete agony. And around the edges, Vert was a lot more generous than just a trickle. Uni could only scream and scream and scream as she felt her most sensitive skin protest so violently against the harsh treatment.
The oil was different from the water. It took too long for this to finally sink in. Water flowed freely, most of the heat leaving with it as it spilled off the edges of the table. Oil was slower, stickier. Eventually, most of it would slide down Uni’s skin and off of her, especially where Vert poured on entirely too much. But until then, its heat was being lost only to the air, and Uni’s own body. And the oil started so much hotter than the water ever was.
All that is to say, it wasn’t until Uni felt Vert’s mouth around her big toe once more, that she realized the oil really was all gone. At least, there was none left for Vert. Uni was still covered in it—though the oil on her feet might be a bit cooler now, having sat there so long. Cool enough that Vert could brush away some of the excess and start tasting her burnt skin once more.
The inside of Vert’s mouth was hot. It wasn’t at all soothing the way the cold water had been. But it was far cooler than the oil had been, and Uni welcomed even the smallest distraction to take her attention away from her burning pussy. Vert’s mouth wasn’t gentle, but it was definitely distracting.
Uni’s moans grew more desperate all the same. The pain between her legs was only getting worse and worse, harder for anything to distract her from it. Eventually even Vert was forced to take notice—if only due to her efforts failing to provoke any sort of reaction.
“Poor Uni-chan…” Vert said, eye’s fixed on Uni’s pussy, “It hurts so badly, doesn’t it? I bet you’re just dying to take a little dip in the tank again~”
A flash of fear hit Uni. It was perhaps just a turn of phrase, but the idea of dying in the tank, of Vert trapping her inside and leaving her there, felt a bit too likely for comfort. Uni tried to ignore than feeling. If Vert wanted to kill Uni, she had plenty of opportunity.
“Please, Vert!” Uni begged once more, “It hurts! The oil’s still there—I need it out! I need it gone!”
“Soon, soon,” Vert reassured her, though lacking the urgency Uni so desperately wished to hear from her, “Now that you want it so badly, I just have one thing to ask you, Uni-chan…”
Uni’s heart sank. She knew, to the core of her being, she would agree to nearly anything, if she could get back in the water tank. Even if it would mean enduring another agonizing black out—and trusting Vert to pull her out afterwards.
“Oh! Nothing bad, I promise,” Vert continued, “I just want you to cum for me~”
Uni’s eyes widened, as she felt Vert’s fingers find her pussy, still hot and slippery with oil.
“Yes, yes. I know it hurts. I know that makes it hard to cum right now,” Vert said, her fingers starting to move, “But I just want to make sure you enjoyed this a little—is that too much to ask?”
Vert could ask whatever she wanted. Uni would be helpless but to obey. And Vert was right. The burns did make it all so much harder—impossible, maybe. Vert’s fingers rubbed against her folds but Uni could only feel pain. It wasn’t even just from where Vert’s fingers touched. Uni’s entire pussy was still on fire, even now that the oil was starting to grow cooler to the touch. There was too much damage done already, and it would get worse every second Uni was kept up here.
Uni reached deep inside her. She needed to cum. Not out of lust, but out of pure self preservation. She couldn’t even approach a climax though. Vert’s fingers were too vigorous, too much to ignore. Uni was hopelessly tangled up in the pain, with pleasure so hard to find. She began to hump her hips anyway, against Vert’s hand.
Uni began to moan again. She needed to work herself up in every way she knew how… though both her chest and pussy alike carried so much pain with them. But the pain was all Uni had left, so she clung to it all the same. Tasting so many kinds of pain today, Uni had developed a sense of which ones felt better than others. If she focused on only the most pleasant pain, maybe it would feel something like pleasure
Vert’s fingers knew none of Uni’s thoughts, but seemed to instinctually read Uni’s reactions. For once, Vert was trying to make her feel good, rather than miserable. Or at least, choosing the sort of miserable Uni could trick herself into thinking felt good.
Uni’s hips grew more frantic, not of her own accord. At some point her body gave in, allowing Uni to seek out those nicest pains, just the same as pleasure. Uni let the feeling take her. It was beginning to feel familiar. Like she was getting closer and closer…
Uni’s moans grew lewder, even laced with clear hints of pain. She didn’t care what she sounded like. She could only chase her orgasm with utter desperation. Uni wasn’t even thinking of the need to treat her burns afterwards. As the moment closed in, her mind was filled with only pain, and growing, unmistakable bliss—
Vert pulled her hand away.
“Sorry, sorry, Uni-chan,” Vert said suddenly, though not sounding as remorseful as her words would imply, “I got carried away… there’s no way you could ever cum like this.”
Uni could only let out a miserable whimper, as the pain turned back into pain, and the moment was lost. Vert unstrapped her arms and legs once more, standing opposite the water tank.
“Now take a really big breath for me, Uni-chan~”
Uni closed her eyes, and let it happen.
