Those who ignite the flames of war must inevitably face the bombardment of the artillery. Tsunade was currently acting as the perfect demonstration of this profound truth.
Saiki had been such a pure, innocent boy; the fact that he had transformed into this relentless beast was entirely Tsunade's fault. Therefore, she alone had to bear the consequences.
"Saiki... no more... I..."
Having been filled to the brim by him once again, yet sensing that Saiki showed absolutely zero signs of stopping, Tsunade—feeling as though she had already ascended to heaven multiple times—tried to beg for mercy, but she couldn't even articulate a coherent sentence.
Given Tsunade's thirty years of accumulated desire and her fully ripened physique, her stamina shouldn't have been this weak.
However, fearing she might fight back and kick him out of bed, Saiki had used his Qi to completely seal her chakra. Without chakra, a ninja's physical constitution—no matter how strong—was merely human.
Saiki, on the other hand, already possessed a physique that far surpassed a normal ninja's. Having undergone the dual cultivation process, his physical limits had been significantly elevated. How could Tsunade possibly hope to withstand him?
Despite her pleas, Saiki had no intention of stopping.
After waking from his coma, although he didn't know exactly how things had progressed to this point, he knew he had needed a woman for dual cultivation. Regardless of whether Tsunade had been forced or had volunteered, he was absolutely determined to cherish this opportunity and mold her completely to his desires.
Saiki grabbed Tsunade by the waist and effortlessly flipped her over, forcing her onto her hands and knees.
Drip, drop.
Seeing Tsunade trembling on the bed, her mouth slightly open with drool and traces of his essence trailing down her thigh, Saiki, having already made his decision, grew even more intensely aroused. He reached out and gripped her slender, yet softly padded waist.
Recovering a sliver of clarity after descending from her dizzying high, Tsunade instantly sensed danger. Forced into this humiliating posture and feeling his hands lock onto her waist, she knew exactly what he was planning.
"Saiki... no..."
She tried to push herself up with one arm while reaching back with the other to shield her lower abdomen from him. However, with her entire body sealed by Saiki's restraint jutsu, she possessed absolutely zero strength to push him away.
As her hand reached back, Saiki excitedly grabbed her wrist.
"You little bastard... stop right now!" Perhaps fueled by a mix of anger and terror, Tsunade finally found the strength to curse him properly.
During the initial phase of the dual cultivation treatment, she had indeed thrown herself into it. But she could always rationalize that as a necessary medical procedure to save his life. Now that Saiki had clearly recovered, continuing the act entirely changed its nature. For Tsunade, this was completely unacceptable.
Faced with her furious reprimand, Saiki simply declared loudly and passionately, "Sister Tsunade, I love you! I've liked you for a long time! Be my woman!"
Hearing Saiki's sudden confession, Tsunade panicked. "I don't want to be your woman! What happened earlier was just..."
She desperately wanted to explain that the dual cultivation had been a last resort, an act of absolute necessity. But it was glaringly obvious that Saiki wasn't going to listen to a word she said.
Feeling Saiki pressing against her, seeking the entrance once again, a terrified Tsunade screamed, "Don't! No...!"
But it was too late. "Nngh!" A sharp cry of defeat escaped her lips as her raised torso collapsed limply back onto the bed. Saiki had already breached her once more, driving deep and hammering relentlessly against her womb.
"Bastard!" Enduring the electrifying, bone-melting pleasure he forced upon her, Tsunade bit her lip and cursed him.
Knowing he couldn't give her another chance to speak, Saiki pulled one of her arms taut, anchoring his other hand firmly on her waist for leverage, and began thrusting his hips with brutal force.
In his previous life, Saiki had often read crude internet jokes about using a massive "weapon" to "train" a woman and mold her to one's desires. However, having only ever visited massage parlors, he had never actually had the chance to test the theory, and he knew most of those jokes were just exaggerated fantasies.
But with Tsunade... knowing her temper, he considered himself lucky if she didn't murder him tomorrow morning, let alone give him another opportunity like this.
Regardless of whether the internet jokes held any truth, and knowing this might be his only chance, Saiki was determined to make tonight count and reap every possible benefit.
Faced with Saiki's storm-like assault from the very beginning, "Nngh... ah... ah!" Tsunade couldn't stop the continuous, helpless whimpers escaping her lips.
Forcing herself to endure the overwhelming waves of numbing pleasure he relentlessly delivered, she shouted in a fragmented, breathless voice, "Bas... bastard... stop... stop it right now... ahhh!"
But the louder she screamed, the harder Saiki thrust. Breathing heavily, he roared back, "Sister Tsunade, I want you to be my woman!"
Wave after wave of electrifying pleasure crashed over her. Tsunade's flushed face wore an expression of sheer, overwhelmed ecstasy. Her eyes grew hazy and unfocused, her soft pink lips parted slightly, yet she still struggled to speak, "Nngh... ah... stop... if you don't... stop... tomorrow, you... get the hell out..."
Hearing her breathless, furious threats, Saiki felt a brief flicker of fear in his heart. But looking down at the elegant curve of her back, her plump, reddened peaches bouncing with every impact, and the tantalizing side-profile of her massive breasts swaying violently beneath her, his resolve hardened to steel.
Ignoring her threats, Saiki tightened his grip on her wrist and waist, accelerating the savage rhythm of his thrusts.
Amidst the loud, rhythmic smack, smack, smack of flesh colliding, and Tsunade's helpless, overwhelmed moans, Saiki panted heavily and yelled, "Sister Tsunade, I love you! Even if you kill me, I'll never leave you! I am going to make you mine!"
Subjected to Saiki's hurricane-like assault, Tsunade felt her mind teetering on the absolute brink of collapse. Yet, hearing his unwavering, fierce confession caused her heart to tremble violently.
"I... I don't like you! Get off me... ahhh..." Fighting desperately against the overwhelming sensations, Tsunade loudly rejected him.
This time, Saiki didn't bother responding with words; he poured all his energy into plowing her. He refused to believe he couldn't make her fall for him. Even if she didn't love him now, he was going to turn her into his exclusive property.
Their battle was incredibly fierce. Fortunately, Tsunade's estate was isolated, with no neighbors nearby, and she had knocked Shizune out cold earlier.
A young boy is still a young boy. Despite Saiki's monstrous physique, his stamina couldn't infinitely match that of a fully matured, ravenous older woman like Tsunade. Before long, a familiar, tingling buildup began to gather at the base of his spine.
Considering the intensity of Tsunade's resistance and his own impending limits, Saiki realized that without the aid of dual cultivation, relying purely on physical pleasure would never be enough to truly conquer a woman of her caliber and turn her into a willing slave to his touch.
Having figured out the key, Saiki seamlessly synchronized the circulation of his Pre-natal Qi with his physical thrusts.
Although her physical strength was sealed, Tsunade had still been managing to barely endure his lustful assault. But suddenly, something shifted. The familiar, electrifying flow of chakra from their earlier dual cultivation began to cycle through her once again, and the intensity of the stimulation instantly magnified tenfold.
No, it was more accurate to say her body had become ten times more sensitive. Purely physical collision was a minor stimulation for a powerhouse like Tsunade. But dual cultivation was a union of essence, Qi, and spirit—a blending of soul and body. Under this assault, Tsunade broke almost immediately.
"Nngh... ah... slow down... please..."
Hearing her finally beg for mercy, Saiki knew he had found the winning formula. He had finally discovered how to truly conquer her.
Under the influence of dual cultivation, Tsunade lost all remaining capacity to resist.
Due to the height difference, Saiki's legs were shorter than hers, making the angle slightly awkward. To gain better leverage, he shifted into a half-crouch, unleashing an even more devastating, explosive barrage of artillery fire.
The ferocious pace couldn't last forever. Soon, both of them reached their absolute limits. Saiki released his grip, collapsing fully onto her back. After a few final, shuddering thrusts, he wrapped his arms tightly around her. Pinned beneath him, Tsunade, gasping for air, trembled violently as she met him at the peak.
