Work Text:
They had spoken of this night many times before – in hushed whispers, entwined in bed. Captain Unohana had assured Isane that she could say no, that she was aware she might be asking for too much. But Isane could never deny her captain anything. Besides, Isane would be lying if she said that Unohana’s request didn’t make her heart flutter. Of course she wanted to share something so intimate – so intense – with her beloved captain.
Unohana looms above her, her usually braided hair falling loosely around her face and shoulders and drowning out all else. Isane can see the scar in the center of her chest – a secret shame that only few know – and moves to deliver a reverent kiss there. Only Unohana has other ideas, and pushes Isane down into the futon. She shivers, her naked skin making contact with the soft cloth of her captain’s robes. Unohana takes a solitary, elegant finger and traces a line up from Isane’s belly to the hollow of her throat.
“Good girl,” Unohana murmurs. Her voice is dark and commanding, worlds away from her usual dulcet tone. “Do you remember the rules?”
“Yes,” Isane replies breathlessly. Unohana has barely touched her, and yet her body is already on fire.
“Tell me, dear one.”
“Kamaboko means stop.”
“And?”
“Manju means more.”
The captain’s smile is beatific as she peers down at her prey. For a moment, Isane’s fears are soothed by this smile, a reminder of her captain’s warmth and kindness. She knows that Retsu will never really hurt her. And yet the smile doesn’t fully reach her eyes. Those blue gems are hungry as she reaches behind her and produces a small blade.
“Ready?”
Isane nods, swallowing. “Please, captain.”
Unohana pauses. “No formalities tonight, Isane. Call me Retsu.”
When she lowers the knife, Isane can feel her heart beating faster in anticipation. She squeezes her eyes shut, expecting pain, only to feel the cool edge of the blade pressing lightly to her neck. Unohana drags the flat end of the knife along her throat, moving slowly and painting patterns along soft skin. Her motions are gentle enough to not break skin, only tease, as she forges a path down to Isane’s hip bones.
“All right?” Unohana asks.
Isane’s eyes flutter open. “Yes,” she replies.
It’s only when Unohana’s blade presses lightly against her clit that Isane moans, “Manju.”
The first cut is superficial. Isane can barely feel the blade’s sting as it makes contact with her stomach. Unohana’s eyes meet Isane’s as she leisurely bends down to lick away the blood slowly trickling from the wound she’s created. Knowing Isane is watching, Retsu’s tongue runs along her upper lip, catching any traces of blood left. The smile she flashes – teeth bloody – makes Isane throb with need.
As if sensing her desire, Unohana shifts and pushes a knee between Isane’s legs. The sound the other woman produces is music to her ears, and Unohana creates another wound – this time directly above Isane’s right breast.
“Watch,” Unohana demands.
Propping herself up on her elbows, Isane observes how the blood seeps down her breast, catching the nipple, then rolling down her abdomen. Unohana’s lips are suddenly on her, creating a seal around her nipple and sucking until Isane cries out in pleasure. She can’t help but thread her fingers through Unohana’s hair, who growls in approval as the sucking turns to biting.
“Manju!” Isane cries, rocking her hips into Retsu’s clothed knee.
Unohana meets Isane’s plea with another sharp cut, this time deeper than before. Isane moans piteously as Unohana presses a finger into the wound and smears the blood across her chest. It hurts, yet the pain melts into pleasure as the captain replaces her knee with skilled fingers.
Retsu is delighted when her fingers come away wet. She takes her fingers, stained with blood and slick, and presses them to Isane’s mouth. The younger woman accepts the intrusion readily, parting her lips so that they can slide in with little resistance.
“You are such a good girl for me,” Unohana encourages. She begins to pump her fingers, groaning while the lieutenant’s tongue swirls around her.
The knife finds purchase between Isane’s breasts, creating a laceration that mimics Unohana’s own. A fleeting thought comes unbidden in Isane’s mind – that she doesn’t want Unohana to heal this particular wound – before Unohana’s fingers leave her mouth with a loud “pop.”
Many more cuts are made all over Isane’s chest, stomach and thighs. Just as her captain had commanded, Isane watches as the blood drips down and stains the sheets below. Even Unohana’s captain’s coat is dyed red – a color that Isane thinks looks lovely on the raven-haired beauty.
“Do you want more from me?” Unohana whispers, breath hot in Isane’s ear.
She can barely utter the word please before the blade slices again into her skin, this time so deep that Isane is teetering on the edge of what she can endure. The pain sings through her body, only to be replaced with bliss when Unohana finds her cunt and slides her hand through the wetness that has accumulated there. Two fingers push inside, and Isane clutches at the stained robe of her captain, moaning and panting with shameless desire.
“That’s it,” Unohana hisses.
The knife clatters on the floor, forgotten, as Unohana begins to move her arm. Tears pour from Isane’s eyes, so overwhelmed she is by the pleasure and pain her captain is freely giving. Her hips buck wildly against her captain’s hand. Isane can feel the sharp pain cut through the pleasure, but the pleasure wins out – especially as Unohana’s thumb begins to glide along her clit.
It doesn’t take long before Isane’s world falls apart. A single image is burned into Isane’s brain – Retsu’s hair sticky and messed with blood, her lips painted crimson, her chest heaving with labored breath, her expression dark and wanting – before she comes on her captain’s fingers. Unohana continues to pump her fingers, fucking Isane through it and into another orgasm, more powerful than the last. All the while, she hums encouraging words for her lieutenant: You’re so good for me, sweet girl. That’s right, come for me. I’ve got you.
When Isane comes back down to earth, the pain in her body begins to intensify, blooming in her chest and spreading all over. Without the pleasure drowning it out, the discomfort pulses. Her mouth moves to form the words kamaboko, but all that emerges is a deep whine.
Unohana presses a kiss to Isane’s forehead. Her darkened expression is gone, giving way now to gentleness. Her palms hover above the injured skin of her lieutenant as she summons the green light of kaido. In a moment, Isane’s wounds begin to stitch together and the pain she felt becomes a distant memory.
“You did so well,” Unohana compliments, drawing Isane into an embrace. “I’m so very proud of you.”
Isane snuggles deeper into her captain’s arms, feeling awe and gratitude that she is one of the only people to see this side of her. With one eye open, she regards her mentor with a hopeful expression. “Maybe next time we can try kido.”
Unohana raises a solitary eyebrow. “Oh? And what do you propose?”
“How about binding?”
That hungry look gleams once more in Retsu’s eyes. “I’m sure we can arrange that.”
