As Tsunade engaged in Dual Cultivation with Saiki, his Pre-natal Qi began to circulate more vigorously.
Having recovered a shred of his strength, Saiki slowly drifted back toward consciousness.
Tsunade had utilized medical techniques to knock him out, but the very nature of their union meant his spirit was being nourished.
His awareness returned like bubbles rising from the depths of a dark ocean, surfacing one by one.
The first thing he sensed wasn't sight or sound, but the familiar, powerful flow of energy cycling through his meridians.
It was drawing in the surrounding natural energy, bathing his weary cells in vitality.
Then came that unmistakable sensation of warm, wet inclusion.
As the energy bridged between their bodies, every completed cycle brought a qualitative leap in his recovery.
Soon, his hearing, sight, and touch returned in full force.
The half-awake Saiki realized exactly what was happening.
Someone was practicing Dual Cultivation with him—and with an incredible amount of "enthusiasm."
Feeling that tender pressure and the rhythmic friction of her grinding against him, Saiki's already rapid heartbeat spiked.
His breathing grew heavy and ragged.
Fortunately, Tsunade—having already "reached heaven" twice—was too deeply immersed in the act to realize Saiki had opened his eyes.
His vision cleared. Despite his initial guess, Saiki still fought to keep his emotions from exploding.
In the dim light, he could make out a dazzling expanse of pale, snowy skin and cascading golden hair inches from his face.
As his focus sharpened, the majestic, heroic, and breathtakingly beautiful face of Tsunade filled his world.
Her gaze was scattered and glazed. Her long eyelashes trembled with every movement.
Beads of fine sweat dotted her forehead, and her pale cheeks were flushed a deep, vibrant rose.
She was biting her lower lip hard, her expression a chaotic mix of intense discipline, agonizing pleasure, and a hint of pained surrender.
As Tsunade rotated her soft waist, her plump, fleshy peaches rose and fell in a rhythmic dance.
The sensation of their intimate connection was overwhelming.
The surge of Yin and Yang energies acting as a healing catalyst was rapidly refilling his hollow core.
Saiki knew his own condition was critical; he hadn't expected Tsunade to sacrifice herself for him again.
Feeling her "gentle" inclusion, Saiki was so excited he practically wanted to leap for joy.
She continued to sway her hips, greedily demanding wave after wave of pleasure.
As another peak approached, Tsunade was forced to pause.
She exhaled a cloud of hot, fragrant breath from her nose and mouth.
Having already come twice, a normal woman would have been spent.
But after years of "drought," this sudden "rain" had awakened a hunger in her that was seemingly bottomless.
Fortunately, Saiki's constitution was monstrous. Even after "submitting his homework" once while unconscious, he was still standing at a proud, rigid salute.
Of course, Tsunade would never admit—even to herself—that she was a "starving woman."
She kept repeating the mantra that this was all "to save Saiki."
After a brief recovery, Tsunade braced her slender hands on either side of Saiki's chest.
Her muscular thighs and narrow waist began to exert force again.
As she gave herself over to the sensation, her eyes finally drifted down to Saiki's face.
Throughout the process, she had avoided looking at him.
The idea that she was "exploiting" a boy made her feel a crippling sense of shame and guilt.
And that's when she saw it.
Saiki's eyes were open.
Those amber orbs of hers crashed directly into his awake, though slightly dazed, gaze.
She froze.
A flash of panicked horror crossed her eyes, followed instantly by a thick, suffocating wave of embarrassment.
She hadn't expected him to wake up so soon, let alone catch her in the middle of such a compromising act.
Every excuse she had—"for the treatment," "I had no choice"—withered and died under the clarity of his stare.
Her body went rigid, her muscles tightening around him as she stopped moving entirely.
Finally, she managed to stammer out a frantic, shaky question.
"You... you're awake?"
Tsunade's voice trembled with a vulnerability she couldn't hide. The second the words were out, she regretted them.
She tried to force herself to be calm, to adopt the detached persona of a doctor, but the flush spreading across her face and the way her body spasmed against his betrayed her internal hurricane.
Saiki blinked. Through his nerves, he felt every pulse of her internal tightness and her frantic panic.
He felt the life returning to his limbs and the Sage energy refilling his "Sea of Qi."
He also felt her fear, her awkwardness, and the lingering heat of her desire.
He didn't speak immediately. He just watched her.
His deep black eyes reflected the pale moonlight and the absolute mortification on her face.
The air in the room felt solid.
Under his unblinking stare, Tsunade's entire body—from her neck to her toes—turned a vibrant shade of red.
Sensing her tension, Saiki finally gave a soft, confirming "Mm."
In the silence of the room, only the sound of two racing hearts could be heard, hammering against each other across a microscopic gap.
Since Tsunade had stopped her movement, the flow of chakra had stagnated as well.
The silence made her even more uncomfortable. Her eyes darted around, looking for any escape, but there was nowhere to hide.
She took a deep breath, her lips moving as if to explain, but she eventually just pressed them into a thin line.
She stayed exactly where she was, turning her head away to avoid his gaze.
In this state, the legendary Sannin looked incredibly, almost painfully, cute.
She was trembling slightly, proving that her heart was anything but calm.
"Sister Tsunade," Saiki whispered, "you have to keep moving. Otherwise, the treatment won't work."
Hearing his words, Tsunade reacted like a cat whose tail had been stepped on.
Her face burned even hotter as she glared at him, barking, "SHUT UP!"
"Okay, okay. I'm shutting up!"
Tsunade took a lungful of air, forcing herself to ignore his teasing, arrogant eyes.
Her waist and thighs began to shiver uncontrollably, and her massive white mounds heaved with her shallow breaths.
She bit her lower lip and resumed her position.
Her heart was a storm—worry for his recovery, shame for her own arousal, and an indescribable web of emotions that made it hard to draw breath.
The moonlight spilled through the window, catching his dark eyes.
In them, she saw only her own reflection, so clear it made her soul ache.
Saiki stayed quiet. He lay there, letting her warmth and softness swallow him whole.
A few minutes passed, and Tsunade still hadn't resumed a proper pace.
Saiki's skin was crawling with anticipation. He wanted to tell her to pick up the speed, but he feared the inevitable scolding.
They stayed in that stalemate for a while. It had been so long since their first time, and Saiki had been craving the legendary Sannin every single night.
Now that she had delivered herself to his door, he couldn't just lie there.
Since he was no longer unconscious, Saiki's instincts took over.
He began to experimentally roll his hips, testing the waters.
Tsunade was usually so bold and boisterous, yet now she was acting like a timid bride.
If they were a normal couple, she would have been the one in control.
But their relationship ensured that she could never truly "let go." She was perpetually tied in knots.
Feeling Saiki's proactive movement, Tsunade nearly exploded with rage.
But remembering his weakened state and the "necessity" of the act, she forced her anger down and simply endured.
Saiki was nervous. He feared a sudden rampage from her.
But seeing her remain silent—seeing her actually accept his small movements—made his heart sing with joy.
To him, her silence was a form of consent. It meant they had officially moved past the "accidental" phase.
As Saiki grew bolder, the conflict in Tsunade's heart intensified.
"This brat is taking it too far" fought against "Well, it's already happened anyway." Several times she wanted to call a halt, but the words wouldn't leave her throat.
Was the Dual Cultivation working? Absolutely.
Tsunade had checked his vitals; otherwise, she wouldn't have kept going for so long.
As for whether her own secret desires were playing a role... only she knew the truth.
Saiki wasn't just enjoying himself; he was actively circulating his Qi to maximize the recovery.
If this were just mindless sex, Tsunade likely would have flipped the table by now.
Her tacit acceptance made Saiki lose all restraint.
Seeing her biting her lip and struggling to stay quiet, Saiki reached his own limit. He couldn't stay on the bottom any longer.
Perhaps Tsunade realized the "treatment" was reaching its climax.
When Saiki suddenly sat up and pinned her against the mattress, she offered far less resistance than he expected.
Even her "struggle" felt half-hearted.
"Wha... what are you doing? Let go of me!" Tsunade stammered.
Saiki didn't answer. He wrapped his arms around her, captured her mouth with his, and launched his final charge.
Amidst the sound of wet, rhythmic slapping, Tsunade let out a muffled whimper.
She didn't bite his tongue; instead, her legs locked around his waist in a vice-like grip.
Her heart had already made the decision for her.
With a final, sharp cry, the fertile soil was nourished once again.
As Saiki pumped his healthy, vigorous seeds into her, their sweat-slicked bodies remained locked in a fierce, crushing embrace.
