Chapter 337 Maria, Transform!*
Edited by: Kanaa-senpai
Fingers traced the length of the slick, delicate crevice, parting the soft petals until the tender flesh at the center bloomed like a crimson flower.
Aki leaned in, his mouth covering the vulnerable mound. A treasure like this demanded to be savored fully—otherwise, once the Great Dragon had its way with her, he would be left waiting until the next chance.
His rough tongue danced, a wild rhythm against the exposed, pale skin.
After tasting his fill, Aki pulled back, admiring the view. “Maria, no matter how many times I look, you are absolutely breathtaking down here,” Aki said with a smirk.
The Succubus loli (a young demon girl), aware of Aki’s gaze lingering even in the deepest, most hidden folds, flushed a deep, bright red. She tilted her head away, her face burning, only making her look more tempting.
Aki pressed down on her rising hips, doubling the intensity of his tongue work.
He latched onto the fully opened petals, his tongue flicking upward with force, digging into the folds between the walls of flesh. With his fingers, he spread the wet, rose-tinted lips wide, sucking firmly on her most sensitive spot. He drank the overflowing, sweet liquid until the hidden valley—now covered in a mix of her own fluids and his spit—shone like an enchanted shrine. The pink petals deepened to a bright red, the small, hidden folds within trembling without stop.
Maria arched her back, offering her delicate flower valley entirely to his tongue. The small mound began to swell, and even she could feel the rising tension.
Aki’s tongue continued to swirl, teasing the center of the crack. The growing desire made the Succubus loli’s body shake violently.
A soft, wet sound came from between her thighs, mixed with the short, breathless moans escaping her lips.
Maria gasped, “Ah… ah… Aki-niisama… no… not there… please, no…”
Gasping for air, Maria could only give in as her petals were teased and tormented by Aki’s stubborn fingers and tongue.
Just as she reached the edge of climax, Aki stopped, gently flipping her over.
His eyes locked onto her backside. The delicate, rose-bud-like rear opening pulsed with her breath, opening and closing like a living thing.
The red, tender bud was just as tempting as her flower valley, and to Aki, it was the most beautiful thing in the world.
Maria fell from the heights of heaven, a deep sense of loss aching in her chest.
But then, Aki reached out. One hand went back into her flower valley to continue its rhythm, while the other traced the curve of her round bottom, sliding slowly toward the small, pink seal between her thighs.
The sudden touch lit the fire in Maria’s loins again. She realized then that Aki hadn’t been teasing her; he just wanted to shift his focus to a more secret, private spot to continue his feast.
A wave of intense, deep pleasure flooded her, but the feeling of a finger pressing toward her rear awakened a fresh wave of shame.
The Succubus loli tightened herself without thinking, crying out in panic, “Aki-niisama… please… not there…”
Because of her small size, Aki had kept from touching her rear before, but he had no intention of letting her off so easily this time.
Maria’s head swayed without thinking to the rhythm of his fingers moving inside her, her nose filled with wild, breathless whimpers.
As his finger entered her rear, the sight of her delicate, wrinkled bud shrinking in panic only made him more excited. He pushed his long, slender finger deep inside.
Maria groaned, “Ah… ah… it is… too much…”
Maria felt her rear completely filled. A mix of intense shame and a burning, trapped heat made it hard for her to breathe.
Between the invasion of her rear, the strong thrusting in front, and the way Aki licked the backs of her thighs, Maria’s whimpers changed from bitten-back hums to soft, wanton cries of “Ah… ah…”
Aki pulled the bud open, showing the fresh, tender inner skin. Maria let out a sharp “Ah!” without meaning to, and squeezed her eyes shut, her neck arched in shame.
A true Succubus—and a strong one at that. The sight of her clean, tender bud was enough to sharpen anyone’s appetite.
Aki pressed his tongue against the exposed flesh, sucking and licking. There was no bad taste; instead, a faint, sweet smell rose up to greet him.
Aki lifted his head, a playful smile on his lips. “Maria’s rear is so sweet. What is there to be embarrassed about?”
With that, he ducked his head again, losing himself in the feast.
Maria’s arms and legs went limp, her naked body twitching and twisting in a useless attempt to push him away.
But it only made Aki more playful. His hands, busy squeezing her soft breasts and teasing her entrance, only moved faster.
The tiny, cute Succubus loli in his arms was no different from a toy he could move however he liked.
Under the pressure, Maria struggled, yet her body followed Aki’s movements with a betraying, rhythmic grace.
Little by little, she could hear the wet sounds of her own fluids, mixed with her high, pleasure-filled cries, answering Aki’s actions in a dirty, perfect harmony.
Just as Aki was having fun, five pink Magic Circles (glowing rings of magical power) appeared above the bed.
A big, fancy key slowly came out of the center circle, moving with perfect aim before sliding into the keyhole on Maria’s chest.
With a sharp click, the small Succubus loli was suddenly wrapped in a pale pink glow of Mana (magical energy).
Inside that unclear, shining light, Maria’s small body began to grow. Her tight black leather suit tore apart, replaced by a new shape made of Mana.
The new outfit was even more revealing, barely covering a third of her full breasts, showing off the hot, tempting nature of this new form.
As the glow faded, Aki saw Maria—now taller than him, with long, thin arms and legs and a tall, full-bodied shape. He licked his lips without thinking.

The loli form had its charm, but this grown-up, long-legged figure was exactly his type. Those legs, well over a meter long, were practically an invitation to sin.
Aki knew she had this form, but he hadn’t expected her to use it now. Excited as he was, he couldn’t help but feel a small doubt.
”Maria, this form uses a lot of strength, you know. I can control my own size — you do not have to go out of your way to become like this,” Aki said.
Maria proudly pushed out a chest even bigger than Naruse Mio’s, “Hmph. I want to let Aki-niisama know the power of us Succubi, to be completely under my body.”
”Then are you going to use the Succubus Baptism?”
The Baptism was a special ability of Maria’s line of Succubus, only usable during the first time, making the man who takes their virginity fall deeply in love with them.
At the same time, it created a deeper desire for their body during the act, like a kind of mind control.
”Hmph-hmph, scared now?” Maria teased. “Even if it is Aki-niisama, if I use the Baptism, you will only become a male dog who knows how to want me.”
”Is that so?” Aki replied.
Aki sneered. He knew Maria was just talking big, but he still decided to teach this sassy little brat a lesson.
”Come on, use it quickly. Do not say I did not give you a chance.”
The Succubus loli… or rather, the Succubus onee-san (big sister), was stunned for a moment, hesitating slightly.
”It is fine. At worst, you can just let go of the control afterward,” Aki urged.
Mind control had almost no effect on him. If Maria used it, it would only make his fun that much deeper. But he wasn’t about to tell her that. He could use it as an excuse to play with this long-legged, virgin Succubus as much as he wanted, and he wouldn’t stop until Maria was a drooling mess.
Seeing Aki’s confidence, Maria stopped hesitating. Her purple eyes glowed with Mana as she looked at Aki.
Meeting Maria’s eyes directly, Aki felt a rush of basic instinct, but it wasn’t nearly enough to break his reason.
Only if he willingly gave in would that power be able to affect his thoughts even a little.
Aki lunged at Maria’s full, tall, hot body, kissing her little mouth hard, catching her slippery tongue and sucking it deep into his mouth.
A grown body was far more open to desire. Maria felt the fire of her lust, which had just barely cooled, begin to burn in her heart with an even fiercer strength.

Trivia:
