The dragon's harem

The ground beneath Arad's feet shattered as he pushed the boulder back. Everyone stared at him, shocked.

"He's moving it!" An adventurer gasped.

"Impossible, how could it be?" Another stared with a distant look on his face.

The earth wizard clenched her teeth, "Damn it!" She ran toward the boulder, "He isn't minding the stability of the wall. At this rate, it will crash on his head. Protect him at all costs!" She shouted, pointing her staff at the wall. [Mold Stone]

Patches of dirt flashed with a brown light, moving toward the wall and filling the cracks. "Hurry! I can't keep the wall standing on my own!" 

The soldiers rushed to climb the wall and remove any stones behind the boulder so Arad could push more easily, "I don't care if your fingers broke! Clear a path for him, right, fucking, now!" The captain shouted, grabbing debris from behind the boulder and tossing it away.

The soldier rushed to clear a path so Arad could push the boulder, doing their best to make sure the boulder got safely moved.

"CRACK!" The wall above Arad's head cracked, and a chunk of it started falling, heading toward his head.

Thud! An adventurer wearing leather armor jumped above Arad's head, swinging his sword at the stone with a smile. CLANG! With a booming sound, the stone shattered into small pieces as the adventurer landed away.

"We'll bully the small stones. Keep pushing, sir s-rank!" The man smiled, tapping his sword on his shoulder, "You can count on us with that!"

"Hell yeah!" Other adventurers jumped in, flinging spells and arrows to blast the debris falling on Arad.

CLANG! An adventurer rushed forward, swinging his Warhammer at a falling brick. CLANG! He gasped. That sound was bad. ^Shit! It had steel inside.^

The brick didn't shatter and instead got deflected, flying toward a mage at a blinding speed. From his clothes, a newbie caster class, a sorcerer, or a wizard wearing the cheapest staff in the market.

The adventurer knew he messed up. That kid was going to die.

ZON! CRACK! At the last moment, a purple aura engulfed the brick, violently pulling it toward the ground.

Everyone froze, and the mages tracked the strange magic back to Arad. The other adventurer follows their gazes.

"Gravity magic?" A fire wizard gasped, seeing the purple aura engulfing Arad's body. "Such intuitive use of magic. He isn't casting spells but molding the magic itself."

"Don't stand near me," Arad growled as the boulder got pushed away from the wall. The purple aura of gravity magic engulfed it.

Everyone watched with gaped mouths as he slowly lifted the stone up and set it on his back.

"Now fucking way, by the gods." A cleric gasped, his eyes almost popping from his wrinkled face.

BAM! BAM! BAM! Arad's footsteps shook the ground as he walked, the massive boulder resting on his back.

***

Back in the castle.

"Sister, sister. LOOK!" Rey said, standing and staring out of the window.

"It's moving. I see it, sister," Ray stood beside Rey.

Isdis looked out of the window with a smile, seeing the boulder outside the wall, burning with an eldritch purple flame as it slowly moved toward the well. "Strong, isn't he?"

The twin maids stared at her, no emotions on their faces. "That flame, is it magic?" Rey asked.

"Seems like it, he isn't just an ox," Ray added.

"That's gravity magic, Arad seems to be using too much of it that it started appearing like a burning flame. The boulder must be extremely heavy. Look how big it is," Isdis explained.

"I see," Rey.

"Sister saw," Ray

"Meant I understood," Rey.

"Didn't Lady Isdis ask you to look?" Ray.

"What?" Rey.

"What?" Ray.

The twins stared at each other, confused.

Thud! Isdis grabbed their shoulders, "Come on, you two." She smiled, "Arad will be back soon. Let's finish the boring work so we can give him another task."

The twin maids nodded in unison, "By the way..." Rey started talking.

"...If he's that strong..." Ray continued.

"...Won't he break..." Rey kept going.

"...Your hips..." Ray added.

"...Tonight?" They asked in unison.

"Guh!" Isdis gasped, staring at them with a sweaty face. "Talking about that, Aella said I won't get out of it without some pain. By her words, his size alone is a sign of concern."

"Really?" Rey asked with a baffled face, "No wonder that woman Mira spent the whole day asleep after their night." Ray added.

"I already settled myself to it," Isdis sighed, "Look, I even bought soft chairs so I can work tomorrow. And you two would be giving me a massage afterward. I'm sure I won't get out of it without some back pain."

"We can do more than that," Ray said with a passive face but clenching her fists in determination.

"We can tank some hits for you," Rey added, mimicking her sister's pose.

"With both of us, he won't have enough energy to hurt you," Ray said, finally showing a determined face.

Isdis shook her face, "Don't even try. I doubt ten women in a row would be able to exhaust him. I go alone, and get it done quickly."

The twins stared at each other, "How about we exhaust him with jobs today so he can't go at it that much at night?" They said simultaneously.

Isdis lifted one finger but then dropped it. "You know what, you're right."

"Exhaust him to the point he can't move," Ray said with a mischievous smile.

"Then give him a bath and a nice massage so he feels relaxed and sleepy," A grin crossed Rey's face.

The twins looked at each other. "Then he would be too sleepy to go crazy on lady Isdis,"

"Just so you know," Isdis stared at them, "When we tried to massage him before, Mira hit him with a sledgehammer, and he didn't flinch."

"But you managed to massage him," Rey said.

"That means we can do it as well." Ray smiled.

The twins looked at each other, "But if we can't massage him," Their glares got sharp, "We'll use the forbidden technique," They glared at Isdis.

CLACK! Tapping their heels on the ground, they glared at Isdis, "Ashiatsu!"
