That night, at the Nakamori residence.
As the hostess, Aoko Nakamori went to her mother's room after her bath, leaving her own bedroom to Kazuha and Yuu. She wore sexy, form-fitting lingerie beneath a girly pink pajama set.
Thump, thump, thump.
Twirling in front of the mirror, Aoko heard rhythmic footsteps echoing from the end of the hallway.
Ugh... Brother Yuu showers really fast...
She mentally calculated the timing. Originally, she had planned to wait in her room. Once Yuu was done with Kazuha, he would surely come to find her. But curiosity and the stirrings of her own heart pushed her to take a peek beforehand.
Just as Yuu pressed Kazuha onto the bed, Aoko arrived at the door. She had brought the key, but a quick test revealed the door wasn't locked. That saved her some trouble.
Under the cover of Kazuha's moans, Aoko turned the handle and pushed the door open a crack—just wide enough for two fingers. Kazuha didn't notice; she had no energy left, and the sound was drowned out by their activities.
Although his back was to the door, Yuu's superhuman senses alerted him instantly. Sensing Aoko's presence, he chose to ignore it. In fact, knowing the young girl was peeping only heightened his excitement.
Peering through the gap, Aoko adjusted her angle. Knowing the room layout well, she quickly found her target.
A vivid, erotic scene unfolded before her eyes.
On the bed, Yuu was enjoying Kazuha's smooth thighs and bouncy buttocks from behind. His free hands roamed over her youthful body—kneading her firm breasts, circling the pink peaks, and finally sliding a finger between the tender petals of her flower.
The pure, energetic ponytail girl had never experienced such stimulation. The position prevented her from seeing Yuu, and the unfamiliar environment added a strange sense of panic. Yet, this fear only accelerated her physical arousal.
Under the assault of Yuu's fingertips and his steel rod, Kazuha felt a rising heat and a swelling sensation in her chest. Yuu noticed quickly. The nipple on her left breast, pinched between his thumb and forefinger, hardened from the size of a green bean to a soybean.
"Kazuha, do you want it?" Yuu whispered into her delicate ear. "If it feels good, you can cry out. Don't force yourself to hold it in..."
Kazuha's pale face and crystal-like ears turned crimson. As Yuu's large hands continued their mischief on her tender breasts and soft petals, she could no longer suppress the pleasure and let out a soft moan.
"Mmm..."
That moan was like a signal to open the gates. The tightly closed petals of her garden parted slightly, revealing a hint of the gap within.
Sensing this change, Yuu's lust flared. He quickened the friction of his finger against her petals while sinking his hips lower, trapping Kazuha's slender legs between his own. Her soft, elastic virgin thighs clamped tightly around "Little Yuu."
"Hiss! That feels amazing!"
Being squeezed by Kazuha's tender thighs sent a jolt of intense pleasure through him. He took a deep breath to control his excitement and growled, "Kazuha, you're fantastic!"
As his member slid slowly between her thighs, his finger moved faster. He couldn't wait to bury himself inside this top-tier high school girl's garden! Judging by the tightness of her outer petals, she would be incredibly tight inside.
Round, smooth breasts, firm thighs, and an exquisitely tight flower path... The thought stoked the fire in Yuu's heart, and a few drops of pre-cum leaked from the eye of the dragon.
Kazuha, overwhelmed by his caresses, was dazed by the pleasure flooding her lower body. Under the intense stimulation, her body shuddered, and she went limp in his arms.
Yuu paused, worried something was wrong, but realized she had simply been brought to climax by his touch alone.
Seeing she was fine, he didn't stop. His finger continued to rub rapidly against her soft petals.
"Mmm... mmm... no... no... ah..."
Lost in a haze, the girl murmured incoherently as waves of strange pleasure washed over her.
"No, you can't touch there... mmm... it tickles..."
As the pleasure built up, Kazuha's mature body responded further. The gap between her petals widened, and the garden, previously just damp, became slick with nectar.
Noticing this, Yuu used his index and middle fingers to press against her tender petals, gently prying them apart.
"Ah!! It hurts! No, don't do that..."
Though her eyes remained closed, Kazuha's brows knit together in pain. But this time, Yuu successfully bypassed the guards and touched the entrance, which was tighter than his pinky finger.
He used his pinky to push aside the tender flesh, gently probing the forbidden zone no one else had ever touched. Kazuha only frowned slightly, signaling her body was ready to accept the intrusion.
The flesh inside was incredibly soft. Though he couldn't see it, Yuu imagined it was a perfect, unblemished pink. Even with just the tip of his pinky inside, he could feel how tight she was. The soft flesh wrapped around the intruder, trying to bar its progress.
However, physical pleasure was unavoidable. As Yuu moved his pinky in and out of her shallow entrance, a small stream of clear fluid flowed from the depths, wetting his finger. Soon, the tight flesh relaxed slightly, coating the walls in slick juices. His palm, pressed against her opening, felt the wet heat radiating from her.
Kazuha's moans became constant.
"Mmm... mmm... ah, it feels weird... mmm... it tickles... deeper..."
Her sweet cries echoed in the room, making the peeping Aoko flush crimson. Yet, Aoko didn't look away; she watched with rapt attention.
As Yuu continued, Kazuha produced more and more nectar, turning from a trickle into gushes that soaked his palm. Taking advantage of the lubrication, Yuu forced his pinky past the tender flesh, pushing deeper. Before he reached the second knuckle, his fingertip hit something resilient.
"Eep!! It hurts!!!!"
The poke against her hymen snapped Kazuha out of her trance. She cried out and scrambled away from Yuu's embrace. She tried to move forward, to put distance between them, but lying on her side on the bed meant she couldn't get far.
Instead, her movement left her entire backside defenseless and exposed to Yuu.
Yuu, momentarily stunned by how shallow and tight she was, snapped back to reality and stared hungrily at her lower body.
Her buttocks formed a tantalizing curve, trembling slightly with her fear like fresh jelly. Because she had leaned forward, her hips naturally arched upward. From Yuu's perspective, he had a clear view of her pink, tender petals.
Because Yuu had been finger-fucking her, the petals didn't close tightly but remained slightly parted. A drop of viscous fluid chose that moment to slide from the pink entrance, tracing a path over the tender petals before dripping down to stain the bedsheet a dark shade.
Seeing this beautiful sight, Yuu couldn't hold back any longer.
One hand pressed Kazuha's shoulder, pinning the girl flat onto the bed, while the other spread her soft butt cheeks, revealing the equally pink and tender chrysanthemum. At the same time, the girl's narrow entrance became even more apparent.
The hard "Little Yuu" pressed against Kazuha's slippery petals, pushing forcefully inward, preparing to claim the energetic high school beauty's virginity from behind.
"It hurts! It hurts!!"
Kazuha had prepared herself, but her natural tightness meant that even with Yuu controlling his size to the minimum 18 centimeters, it was unbearable.
Yuu was also surprised; it was his first time encountering someone so shallow and tight. Her body was fully developed, an adult's, with hair on her mound, yet the inside was as tender as a child's...
Based on Yuu's experience, Kazuha's garden was similar to Ai's inside. He had played with the fake loli many times, so he had the authority to speak on this. But Ai was shrunk by the drug; her body returned to childhood. What was Kazuha's excuse?
A natural gift?
A peerless "Famous Vessel" (Meiki)?
Regardless, he had to get inside or it was all for nothing.
Seeing Kazuha weeping like a pear blossom bathed in rain, Yuu decided to extend the foreplay.
He reached out a finger to tease Kazuha's petite chrysanthemum while "Little Yuu" pushed forward again. However, he still couldn't pry open the two petals of her lower body. Because the tender flesh was coated in slime, the dragon's head kept slipping outwards against the petals, unable to penetrate.
Although he hadn't truly entered Kazuha's garden, the girl's slippery petals were tender and juicy, reflecting an erotic sheen under the bright lights, bringing Yuu both physical and psychological pleasure.
Before long, he felt the urge to release rising to the tip. He hadn't expected that just grinding (sumata) for a while would feel this good.
He could have released a load first, but Yuu wanted to save tonight's first shot for the main event. It definitely wasn't because Aoko was watching from outside, and he felt it would be embarrassing to finish just like this.
At this point, the forcibly grinded Kazuha was incredibly wet; further caressing wouldn't help. Yet every time "Little Yuu" tried to enter, she cried out in pain.
Seeing this, Yuu had to resort to some cheating methods. Come to think of it, Akane had inspired this just yesterday.
Increased sensitivity, decreased pain, enhanced flexibility...
After a chain of spells, Kazuha's expression finally relaxed. Since it wasn't Yuu's own body and it was his first time using these spells on someone else, he didn't dare apply effects that were too strong, so Kazuha still cried out that it hurt.
Seeing this, Yuu couldn't bother teasing Kazuha's chrysanthemum anymore. Guiding his iron-hard "Little Yuu," he strove to squeeze into the gap between the petals.
After slipping off two or three times, the purple-red dragon head finally forcibly pried open Kazuha's tender petals.
"It hurts!!! It hurts so much!!!" Kazuha cried out again, feeling the foreign object stuffing her lower body.
However, this time it was a normal level of pain, the kind every girl experiences for the first time.
Yuu, having already squeezed half the head in, took a breath. With a powerful thrust of his hips, the rest of the head was slowly sent into Kazuha's garden.
The girl's chrysanthemum opened and closed slightly due to the physical pain. Because her flower path was so petite, both the outer and inner labia were forced to squeeze toward the entrance.
Due to extreme nervousness, Kazuha involuntarily tried to clamp her butt cheeks together, attempting to squeeze "Little Yuu" out.
However, the inexperienced girl didn't realize that doing so brought Yuu unparalleled pleasure.
Her tight entrance and tender petals, due to her clenching, clamped firmly around the coronal sulcus beneath the head. The head, having already squeezed into the garden, was pressed by the tender flesh of the inner walls.
Kazuha's garden contracted desperately. The juice-soaked folds on the fleshy walls rubbed against Yuu's dragon head rhythmically, unintentionally teasing his nerves...
"Hiss... that feels good..."
Yuu panted, continuing to apply force, forcibly pushing deeper.
Outside the door, Aoko instinctively covered her mouth. Watching the thick giant dragon slowly disappear into her best friend's body, she subconsciously clamped her legs together.
When a trace of bright red blood flowed down from where they were joined, she trembled.
As the main event began in the room, Aoko's expression changed constantly.
At first, Kazuha was in pain and crying, and Aoko looked sympathetic and nervous.
Gradually, as Kazuha began to enjoy it and started moaning, Aoko blushed and watched with rapt attention.
Finally, when Kazuha completely adapted and discovered the joy within, beginning to actively respond, Aoko also began to caress her own sensitive body in rhythm with their movements.
Because he had another task tonight, Yuu didn't deliberately hold back. After about twenty minutes—enough to let Kazuha thoroughly experience the joy of sex and climax twice—he pressed against the girl's soft uterine wall and began to release.
Kazuha was very tight and shallow; he couldn't help but "break the womb." Otherwise, he could only enter halfway, which wouldn't be satisfying at all. Fortunately, with the aid of magic, breaking the hymen and breaching the cervix consecutively wasn't a major issue.
After the brief pain, Kazuha immediately enjoyed unparalleled pleasure.
Because she was tight and shallow enough, her body was unexpectedly sensitive. Coupled with the magic assistance...
If Yuu wanted to, he could turn this energetic ponytail girl into the kind of "bitchy nympho" found only in the world of hentai tonight—the kind who would do anything as long as there was a big dick involved. And under the contract's effect, she would only recognize Yuu's member.
Besides Kazuha, Sonoko also had this potential, but Yuu didn't plan to do this yet. It was irreversible, and once trained, it might affect their daily lives. Besides, he could do it anytime; it wouldn't be too late to do so when he felt the time was right.
However, it had to be said that because Kazuha practiced Aikido, her body was quite durable, including that tender, soft floral palace. Added to her gifted tightness, Yuu felt incredible.
Most importantly, the contract went very smoothly.
When he finished releasing, the contract was successfully established. A pink erotic mark appeared on the energetic ponytail girl's lower belly, which bulged slightly from being filled.
Conditions one and two of the contract went without saying; just looking at Kazuha's uncontrollable ahegao face, even if there hadn't been enough love before, she had been fucked into submission now.
As for the third condition, Yuu understood why it was satisfied directly.
Like Akane, Kazuha came from a wealthy family. Almost everything she wanted could be satisfied; she didn't have any outrageous wish she was desperate to achieve.
If anything, Akane's wish before might have been to conquer Kid, while Kazuha's was for Heiji to confess to her.
However, once they decided to commit to Yuu, this wish naturally changed. Either the object of affection shifted to Yuu, or it simply vanished.
Without obsession, the third condition of the contract would randomly select whatever was currently in her mind. It could be drinking water, checking her phone...
In any case, it became very simple. Or perhaps, she simply wanted to feel good, to climax.
And at that moment, being ruthlessly creampied by Yuu and scalded into repeated orgasms by his hot essence...
Contract Condition 3 was directly satisfied.
