Serakuza colpsed onto the ground, exhaling a heavy sigh of relief. His heart still pounded in his chest. Homo Erectus straightened, wiping the sweat from her brow.

  "Phew~. That was fun," she mused, turning to check on him. "You all right, boy?"

  Ft on his back, still catching his breath, Serakuza gave her a thumbs-up, grinning at the sky.

  "We should head back," Erectus said, hoisting the rex’s tail over her shoulder as if it weighed nothing. The mature Tyrannosaurus Rex was massive, and though she carried it with ease, the deep trail it left behind told another story.

  Seeing her leave, Serakuza scrambled to his feet and hurried after her. He cmbered onto the T- Rex's back, cheering her on as they made their way home.

  ---

  Homo Sapiens greeted them with an unreadable expression, her sharp eyes scanning their kill. Serakuza leapt off the Rex, arms outstretched to embrace her—only to be met with a sharp knuckle to the forehead.

  Sapiens, her anger simmering beneath a composed exterior, turned to Erectus. "Dear sister," she said in a calm tone, "I thought I told you not to overdo it on your hunts—or to drag Serakuza into dangers he isn't ready for." Her tone sharpened at the st words.

  Erectus raised her hands in a defensive posture. "Hey, hold on, sis! Let me expin."

  "Speak," Sapiens commanded, arms crossed.

  Erectus unched into an animated recounting of their hunt. When she finished, Sapiens exhaled while pinching the bridge of her nose.

  "Look, we made it back in one piece, didn’t we, boy?" Erectus said, spreading her arms wide.

  Serakuza clung to her waist, nodding fervently. "It’s true, Mother," he chimed in, fshing a doe-eyed look to soften her anger.

  Sapiens’ gre intensified. A bead of sweat trickled down Serakuza’s back.

  In their household, discipline fell primarily to Homo Sapiens, typically manifested as a swift swat on the butt-ery cheeks whenever Serakuza misbehaved. Homo Erectus, on the other hand, was as pyful as he was, often getting them both into trouble. Sapiens had once expined that there was no point in trying to correct her sister, whereas Serakuza, being young, still had much to learn. It felt unfair, but what could he do?

  It also expined why he frequently teased Erectus and why he attempted to initiate something sexual whenever an opportunity arose.

  Sapiens sighed. "Fine," she muttered, turning back to her work. Years of raising him had taught her the futility of constant reprimands.

  Relieved, Erectus let out an awkward chuckle. She and Serakuza exchanged a look and a shared haa~ of relief.

  "You must be hungry," Erectus grinned. "Help me skin this guy, and then we’ll start a fire."

  Serakuza nodded eagerly.

  ---

  By early afternoon, the T-Rex was completely processed. Serakuza handled the meat while Erectus skinned and tanned the hide. Their hard work paid off in the form of a hearty meal—roasted meat over the fire. Sapiens received the rest and prepared a rich stew and simple bread, likely made from wild wheat she had gathered.

  Satiated, Erectus and Serakuza drifted off to sleep, while Sapiens retired to her library. Time passed without disturbance, and soon, evening arrived.

  Sapiens, suspecting the two would sleep through dinner, went to check on them. She was right. Standing by the bedside, she called out in her usual calm voice.

  Erectus' eyes fluttered open, and she sat up abruptly. "Evening already?" she mumbled, rubbing her eyes.

  "Yes, dear sister. Wake him up, would you?" Sapiens said, gncing at Serakuza.

  Erectus shook him with a light touch. No response. The sisters exchanged a look. Then, as Sapiens' gaze darkened, Serakuza’s eyes flickered beneath his lids.

  A second ter—wah!

  He jolted upright and blinked with bleary eyes. Erectus ruffled his hair.

  "Mother, don’t wake me like that," he whined in a faint voice.

  "Then learn to watch the time," Sapiens retorted before walking away.

  Serakuza knew what a watch was—he’d seen them in Sapiens’ books—but here, the only timepiece was the sun.

  ---

  Erectus stretched, then nudged him off the bed. "Up, boy. Time for training."

  Serakuza groaned but followed her outside. Leaning against the house were wooden sticks, roughly the length of swords. Their sparring sessions were always intense—any outsider watching might assume Erectus had a personal grudge against him. She smiled with wide, enthusiastic grin as she swung, the air whistling with each arc.

  "Smile, boy~. You don’t want your enemies running away, do you?" Erectus teased.

  "You damn hag! Will you stop trying to kill me?!" Serakuza cried while dodging with urgency. "Besides, that creepy grin is why they’d run away!"

  "Oh yeah?" she mused, swinging again.

  The air vibrated with her blows. Anyone watching would break into a cold sweat.

  Serakuza saw an opening and struck. But before his stick could connect, Erectus intercepted his arm with her knee—right as her garment shifted, offering him a view of her thigh and a glimpse of her vulva.

  His mind bnked.

  Erectus raised her stick high.

  "Shit," Serakuza breathed.

  "Shit, indeed," she echoed, grinning.

  Her strike nded with a resounding crack. Serakuza tumbled backward onto his rear. Pain bloomed across his skull. He sat there in stunned silence before gring up at her, tears pricking his eyes.

  "That fucking hurt!"

  Erectus slung her stick over her shoulder. "Then dodge better," she said, sticking out her tongue.

  "You damn hag…" he muttered, still clutching his head.

  Sapiens intervened. "You’ll make him stupid at this rate, dear sister."

  Erectus only ughed at her words.

  Turning to Serakuza, Sapiens added, "Get up, honey. It’s my turn now."

  "But Mother, it hurts…" he whined, attempting to look pitiful.

  Sapiens wasn’t moved. "Oh, come now. You already have a strong physique—otherwise, you’d be dead by now."

  Erectus grinned. "I do hold back, you know."

  "Right," Serakuza deadpanned.

  ---

  Training with Sapiens focused on endurance—dodging and resisting her magic attacks. Serakuza ducked and sidestepped to deflect projectiles. But soon, exhaustion took hold as the battle dragged on.

  Sapiens decided to end it. "Let’s finish this," she said, extending her hand.

  A crushing force smmed into Serakuza, forcing him to his knees.

  "Get up and fight, honey!"

  He struggled, his body trembling against the pressure, but he felt spent. Colpsing forward, he gasped for air.

  Sapiens sighed and released him.

  Night had fallen. Serakuza y ft on his back, staring at the darkening sky, relishing the cool breeze.

  "You all right, kiddo?" Erectus asked, squatting beside him.

  He turned his head—only to catch an indecent glimpse of her pussy between her muscur thighs.

  "...Yeah, I’m okay," he murmured in a faint voice.

  Seeing he was still breathing, Sapiens left to prepare dinner.

  "I’m taking a shower," Erectus announced, standing up. "You coming?"

  "Can you carry me, Ma?" Serakuza groaned.

  "Nope," she replied in a monotone voice.

  Wrapped in a towel, she disappeared into the simple bath carved into the hillside.

  "Oi~, you’ll miss dinner if you stay there too long," she called back.

  With a groan, Serakuza pushed himself up with great effort.
