Due to the unique effect of the contract ritual, Rias experienced an unprecedented tingling and blissful sensation.
That wondrous feeling—intoxicating and exhilarating—made her feel transcendent, as if she had ascended to heaven.
This extreme pleasure caused Rias's long, round, snowy-white legs to involuntarily shoot straight up towards the sky, her toes curling and stretching upwards. She was completely immersed in inexpressible joy.
At the same time, Ethan was drawn by the intense pleasure transmitted from his Great Dragon. He felt a suction force emanating from Rias's flower valley, tightly gripping and sucking the invading dragon's head.
The layers of tender, folded flesh within the fleshy walls, mixed with the continuously secreted, slick flower nectar, pressed and ground against Little Akira without any gap.
This feeling of supreme pleasure and ecstasy caused Ethan to gasp and suck in his stomach, thrusting hard with great intensity.
The Great Dragon between Ethan's hips charged like a valiant warrior, brave, fierce, and relentless.
Although Rias still felt a twinge of pain, Ethan's wild and crude movements also ignited overwhelming pleasure in her.
She couldn't help but gasp for air, whimpering, and moaning loudly.
With every thrust of the hot, thick Great Dragon, Ethan hit Rias's sensitive and delicate flower heart with full force.
The raised ridges on the dragon's head continuously scraped the inner wall of Rias's tender, deep valley tunnel as he plunged and withdrew.
That tingling, itchy, yet incredibly joyful sensation made the Devil beauty moan wantonly.
The dreamlike, soul-shattering pleasure surged like a tidal wave. That incomparable feeling of ecstasy caused Rias to involuntarily lift her fair, plump, round hips.
She moved her lower body back and forth madly, coordinating with Ethan's vigorous thrusting.
Rias desperately clung to Ethan, her fingernails unknowingly digging deep into Ethan's muscular arms.
Ethan and Rias fiercely merged like this...
The enormous, hot Great Dragon plunged in and out of the girl's pink flower valley without pause.
It drove Rias's flower nectar to rush out in waves, reflecting an obscene sheen under the light of the magic circle.
Gulp... gulp...
For a moment, flower nectar splattered, and the girl's moans immediately became high-pitched.
"Ah... I can't... I'm going to climax...!"
After about five or six minutes, Rias had surrendered, her beautiful body weakly sprawled at the center of the magic circle.
Looking at the flushed, naked Rias filled with the spring of lust, a powerful sense of conquest surged in Ethan's heart.
He grabbed the girl's full, erect large breasts with both hands and thrust even more vigorously.
"Mmm... it's coming again... Ah...!"
Rias's smooth, white body convulsed violently. A thick gush of Yin Essence sprayed out, a warm current welling up from her tender flower valley and rushing through her limbs, achieving an unprecedented climax.
In her excitement, the girl's sexy, plump upper body arched up, lifting off the ground, forming an upward bow shape.
Rias's delicate body continued to tremble. Slippery nectar surged out in streams from her pink, mysterious flower valley, and muffled whimpers escaped her throat.
Before she had fully descended from the clouds, Rias vaguely felt Ethan flip her boneless, naked body over.
Her consciousness was still hazy, and she could only submit to his handling.
Ethan knelt in the center of the magic circle. Rias lay obediently before him like a lamb.
The hot Great Dragon aimed once more at the slick entrance, and then the girl's body was jolted forward.
With a hissing sound, the entire length of the Great Dragon fully penetrated the pink, alluring, mature flower valley.
"Ah...!"
The intense insertion made Rias cry out involuntarily. To ensure the ritual's success, she gathered her resolve and tried hard to cooperate with Ethan's movements.
Slap—
Slap—
Slap—
Ethan tightly grasped Rias's slender, soft waist, his abdomen repeatedly colliding with her full, elastic, raised buttock as he began another round of thrusting.
Little Akira withdrew completely with every stroke and re-inserted completely, allowing Rias to experience an unprecedented feeling of deep penetration.
"Ah... Mmm..."
Rias's beautiful eyes were glazed over, her red hair disheveled, and her snow-white flesh vibrated rhythmically with the thrusts.
Ethan's body, with its perfect proportions, was pressed tightly against her snowy hips. His hips ceaselessly pumped, and he couldn't help but say, "Akira, this feels so good... you're amazing..."
Rias was now entirely lost in lust. Her sensitive flower valley endured the utterly satisfying penetration.
The pleasure of their coupling caused her plump, snowy, round hips to involuntarily thrust back and forth, accommodating Ethan's activity and producing continuous slapping sounds of collision.
"Ah... Ah... I can't take it...! It's coming again...! Ah..."
One wave hadn't subsided before another arose. Along with the squelching sounds of their union, Rias tilted her head back, her red hair flying. Her delicate body convulsed and she reached the peak again.
Warm, sticky Yin Essence spilled out in torrents from their joined parts, trickling down Rias's sexy, long, beautiful legs and dripping onto the pink-glowing magic circle...
The girl slid down from the climax once more. Although her flower valley and flower palace were still intensely stimulated, her consciousness gradually returned.
Thinking of her previous frenzy, she felt deeply ashamed, not daring to look at her servants around her.
Rias tightly closed her beautiful eyes, her pretty face flushed crimson, and she quietly gasped, "Akira... come out quickly... finish the contract first..."
Looking at the charming girl beneath him, then up at the beautiful girls around him—some glazed over, some curious, some longing—Ethan's mind wavered.
He no longer restrained himself. Driven by the contract magic circle, his Great Dragon slammed against the wall of the sacred flower palace, fully injecting his long-accumulated, thick essence without leaving a single drop.
"Ugh... so much... so hot..."
Rias arched her swan-like, snow-white, slender neck, and two pink heart phantoms flickered in her emerald eyes.
At the same time, the magic circle emitted a beam of magic power light, enveloping Ethan and Rias.
After an unknown period, the light vanished. The intricate, beautiful magic circle on the floor turned into specks of light and dissipated into the air.
In the dimly lit club room, the girls, who possessed Devil blood, still had clear vision.
Amidst quick, charming pants, they noticed Ethan and Rias were still joined, but if they only relied on perception, there was only one life force signature there.
The moonlight outside the window was covered by clouds, then reappeared.
Experiencing the power and benefits brought by the mutated contract, Ethan and Rias exchanged a knowing smile, kissed lightly, and then leisurely separated.
Feeling the stickiness and wetness between her thighs, Rias brought her straight, round, beautiful legs together.
"Akira, I'm going to wash up."
Ethan nodded, gazing at the indigo-blue heart-shaped collar on the girl's neck and the bright red, gorgeous heart crest on her pale abdomen. "Go ahead, but I'll need you to provide proof later."
Rias shot him a look, covered her abdomen with a touch of shyness, and minced off to the bathroom.
"Alright, I know you all have many questions."
Ethan didn't care that he was naked and began to explain to the group of alluring girls.
"Wait a moment, let me think where to start..."
The moment the contract magic circle vanished, the strange sensation in Akeno Himejima and the others gradually faded.
Only the stickiness between their thighs and the heavily soaked panties proved that what had just happened was not an illusion.
Fortunately, apart from Ethan, everyone present was female.
And having witnessed a live show, performed by Ethan and Rias, the few who were not affected were also feeling lustful, so there was no awkwardness.
Time slowly passed. As Akeno Himejima and the others returned to normal, Ethan had also figured out where to begin.
"The Dual Cultivation between Rias and me was necessary to complete the final step of the contract..."
Maria frowned, about to speak, but saw Ethan motion for her not to rush. She then patiently continued listening.
"Due to the influence of my ability, the contract provided by Maria underwent a mutation. Like Dual Cultivation, it is only fully completed after internal ejaculation."
"The change in the magic circle was also due to this mutation, and you were all slightly affected because you were too close..."
Under Ethan's explanation, the girls gradually understood the sequence of events and also learned about the differences in the mutated contract.
