After Rias broke through to SS-class, the Dual Cultivation ability provided a powerful wave of energy feedback to Ethan.
"Hngh... Mmm..."
Gently holding the girl, the supreme pleasure and the rush of rapidly increasing power caused Ethan to let out gasps from deep in his throat.
As the energy was slowly absorbed, Rias's power settled at the initial stage of Upper-Class Devil. The red and blue confluence of magic power briefly flashed, then retreated, re-entering their respective bodies.
Following the breakthrough, the girl's ability to absorb life essence increased again. Her slightly swollen lower abdomen visibly flattened at a speed perceptible to the naked eye.
A few seconds later, it returned to its smooth and firm appearance, leaving only a small, round bulge at the very bottom.
That was the head of the great dragon, still resting inside the sacred FLOWER-PALACE. With the continuous embrace and sucking of the FLOWER-PALACE, Ethan reluctantly withdrew the great dragon.
He looked at the girl on the bed, her expression dazed and her face flushed crimson, a faint smile on his face.
Rias saw Ethan staring at her, a look of confusion on her face. She wiped her cheek with her hand and asked, "What's wrong? Is my complexion bad, or is something on my face?"
Ethan gave her a gentle smile and said, "No, I just think you're so beautiful, Rias. I can never look at you enough."
Even though they had just shared the most intimate act, Rias felt strangely shy hearing Ethan's praise.
"You idiot...." She turned her head away shyly, pouting. "Don't say things like that after it's done..."
Ethan smiled, taking Rias's restless little hand.
"President, let's go take a bath. The night is still very long."
"You little pervert..."
Amidst Rias's half-shy, half-chiding murmur, the two entered the bathroom together.
After a quick rinse, Ethan began to help Rias wash her beautiful, blood-red long hair.
Only by personally washing these incredibly smooth strands of hair could he understand how much effort Rias put in daily.
Although magic power could remove dirt, achieving such natural luster and brightness also required proper hydration and care.
Ethan combed the bright red hair while applying high-quality shampoo. Once the shampoo was evenly distributed on the strands, he gently massaged Rias's scalp with his hands.
Ethan's technique was average; this was his first time washing a girl's hair. But Rias felt it was even more comfortable than when the specialized maids at home helped her wash it.
"All done, President. How does it feel?"
Ethan rinsed all the foam from her red hair with warm water, asking while admiring Rias's seductive, charming body.
After this brief rest, Rias returned to her persona as the cool, authoritative President. She nodded faintly. "Not bad. From now on, my hair is your responsibility."
The Rias from before was cute and tempting, but looking at the President before him, Ethan's heart pounded just as fiercely.
He seemed to like this Rias even more...
Not hearing Ethan's reply, Rias looked over in confusion. Before she could ask, Ethan had already shown her the reason with his actions.
The reinvigorated great dragon unreasonably thrust itself between Rias's beautiful legs. Her small hands instinctively moved down, attempting to block it.
"Rias, only I can wash your hair from now on."
Ethan lightly kissed the girl's pale neck, softly declaring his deep affection and possessive dominance.
Rias let out a soft giggle. Her blocking hands changed to teasing ones, her slender fingers playfully kneading the exposed great dragon in various ways.
Ethan couldn't help but hug her tighter. The girl's full, sexy body was full of youthful elasticity, smooth and warm.
Rias's rosy face pressed close to Ethan's chest, and she extended her wet little tongue to lick his little 'bean'.
Ethan involuntarily groaned again, gripping Rias's round BOOTY, his fingers attempting to tease the girl's moist FLOWER-PETALS.
His fingertip, dampened with warm water, easily parted Rias's honey-clamshell. He gently probed with his fingertip, slowly finding a wet little HOLE. Then, his long finger slowly entered the FLOWER-VALLEY, kneading the tender folds inside.
Ethan lightly pressed his thumb against the already swollen pink 'bud', gently vibrating it, while he lowered his head to kiss Rias's neck and full large breasts.
Rias began to moan. Compared to the frantic moans before climax, this was more like the low, gentle cry of an aroused fawn.
The Devil beauty's body was extremely sensitive. Soon, Ethan's middle finger was thoroughly coated in sticky, warm fluid. The seductive honey-hole trembled, slowly swallowing his middle finger as if possessing suction.
Ethan felt her girlishly hot and tight V-CANAL. Taking advantage of the sufficient lubrication, he drove his middle finger completely in, bending his finger to try and locate her G-spot.
Rias writhed in Ethan's arms in protest, but the friction of their naked skin caused their passion to heat up dramatically.
Soon, Ethan found a small, nail-sized, soft, slick area in the folds above her wall. He pressed the pad of his middle finger onto it and began to rub at a high frequency.
Rias shuddered all over, tightly holding Ethan's back, and tilted her head back, letting out an "Ah."
Her face was flushed and dewy, her cherry lips slightly parted. Ethan saw a look of bewilderment in Rias's eyes for the first time.
As the friction intensified, Rias could no longer control the volume of her moans. She had to lightly bite Ethan's shoulder. Her small throat emitted endless cries of pleasure, and sticky passion fluid coated his hand.
Ethan teased her while kissing Rias's cheek indiscriminately.
Rias's face suddenly lifted, and her cherry lips found Ethan's mouth.
Before Ethan could react, a flexible, tricky fragrant tongue slid into his mouth like a snake.
They embraced tightly, like greedy children desperately demanding the other's fluids, wishing to melt into each other. The showerhead lay on the floor, water spraying everywhere, filling the bathroom with steam.
After an unknown period, the two finally separated, dripping wet.
Lust burned in Rias's eyes as she fixed them on Ethan's handsome face. "Akira... I want you too."
Ethan thrust his hips slightly. The proudly erect great dragon moved in and out between her fair, round, beautiful legs. "Me too."
"Ngh..."
Amidst Rias's unrestrained moan, the memorable night resumed.
That night, the two barely stopped. After the bathroom, it was the sofa, then the office desk, then the balcony, and finally back to the bedroom.
The night of passion was too short. When the golden glow of the morning sun streamed through the gaps in the curtains, the two, who felt no fatigue, finally realized it was morning.
Ethan lay on his side, holding Rias, his head buried in the girl's neck, breathing in her faint scent, thrusting hard below.
"President... this is the last time..."
"Ngh... Okay..." Rias clamped her thighs, trembling as she experienced the ultimate pleasure, gasping, "My stomach... it's full... use your mouth this time..."
"Alright."
Ethan suppressed the urge to climax and withdrew the great dragon from the clinging FLOWER-VALLEY. He skillfully held Rias's smooth, delicate chin and, kneeling slightly, inserted the great dragon into the other soft, wet HOLE.
Even for two SS-class individuals, Dual Cultivation cannot continuously produce the same effect.
In the latter half of the night, Rias and Ethan gradually experimented with more positions and forms of PLAY. Her upper mouth and her incredibly tempting beautiful legs and feet became the main focus of their attention.
As soon as the little Akira probed, the girl's slick, nimble little tongue immediately wrapped around the head of the dragon, constantly rubbing and teasing him to his limit.
"Hnngh..."
Ethan groaned, suddenly thrusting hard. The head of the dragon pressed against the tip of her tongue, fully emptying his still-thick essence into Rias's small mouth.
The Devil beauty tried hard to swallow, her small throat moving up and down, but still, a lot of white fluid overflowed from the corners of her mouth.
"Phew..."
A little over a minute later, Ethan contentedly retrieved the great dragon, which Rias had thoroughly cleaned. However, even as he cleaned it, the recently softened great dragon showed signs of swelling again.
