The bathroom is filled with thick steam.
Hot water and white foam spill over the edge of the tub.
Thirteen-year-old Chris Kendrow soaks quietly, his body half-submerged.
Behind him sits his older sister, Alexia Kendrow, eighteen.
Her legs are spread, and Chris rests between them.
His back leans against her large, soft breasts, like a plush cushion supporting him.
«Today officially begins your adventure at the HESPARC Academy... are you happy, little bro?»
Alexia speaks softly, her hands gently brushing against his chest.
Chris nods in silence, but his heart pounds with emotion.
The HESPARC Academy stands on a remote island in the Atlantic.
It's a special military facility where Monster Reapers are trained—elite operatives who protect the world from demonic threats.
Normally, only those aged sixteen and up are allowed in.
But sometimes, rare talents are admitted early.
Chris is one of them.
Since hearing the news, he hasn't been able to sleep, too excited by the thought of joining.
But that's not the only reason he's so happy.
«Y-Yes, big sis... I'm excited to attend the academy and fight strong opponents... but what really makes me happy is that we'll finally be together every day...»
Chris murmurs with a hint of shyness in his voice.
«Ever since you started going to the HESPARC Academy, I barely saw you. Only during the short visits when you came back home. I've felt so alone without you, big sis...»
«Oh, Chris...»
Alexia sighs, her face red from both the heat and his words.
She wraps her arms around his neck from behind, her chin resting on his shoulder.
Their cheeks touch, skin to skin.
«...I missed you so much too, little bro... I felt so lonely without you, especially at night...»
Alexia's right hand, which was gently caressing his chest, slowly moves down.
Her fingers trail softly to his belly, brushing over his abs.
For a thirteen-year-old, his body is unusually toned.
It's thanks to the intense training required of Monster Reaper families and also to his natural build.
As soon as Alexia's hand brushes over his stomach, Chris jolts.
His breath catches—shallow and uneven.
There's a weight in his chest, something strange and hard to name.
They've bathed together before—the last time was three months ago.
But this time feels different.
There's something new stirring inside him, something he doesn't understand.
«...Sleeping without you at night is so hard...»
Alexia whispers, her voice low and breathless as her hand keeps moving along his belly.
«The bed feels cold... so empty... It's been two years since I started at the academy.
Today begins the third. But I never got used to falling asleep without holding you close.
Finally, that changes today...»
Alexia's voice trembles with emotion.
She hugs him tighter, her arms firm around his chest.
Her breasts press more firmly against his back.
Chris can feel her hard nipples through the contact.
He tilts his head back, resting it against her chest.
Their bodies remain close—almost too close.
Chris lifts his gaze.
He stares into her eyes—deep, beautiful, the same blue as his.
«Y-You're so beautiful, big sis...» he whispers.
His voice is faint, almost trembling.
Alexia smiles.
Her left hand rises, stopping gently beneath his chin.
She tilts his face upward, slowly.
«You too, Chris... you're the most beautiful little bro in the world... I love you.»
Her voice is soft, filled with warmth.
Then she leans in.
Her lips are parted, full and gentle.
Her tongue flicks out slightly—just a breath away from his.
