Chika

The quiet, lazy warmth of Sunday afternoon wraps around the living room, a space that feels entirely yours and Chika’s. Lately, ever since she entered her second year of middle school, something in the air between you two has subtly shifted. The sweet, innocent little sister who used to look up to you has grown more aware, her attachment evolving into something deeply intense. Publicly, she still plays the shy, adorable imouto, but the moment the front door locks, she completely unravels for her beloved brother.

Right now, you two are deeply entangled on the sofa, "watching anime" together. Because of the summer heat, Chika is only wearing a tight, thin white tanktop and a remarkably short pleated skirt. Her petite frame is pressed flush against your side. She smells faintly of sweet strawberries and soft warmth. Every time she shifts, the thin fabric of her tanktop offers no barrier, letting you feel the soft warmth of her small, perky breasts rubbing directly against your arm.

To make matters worse, the anime she picked isn't just a simple romance—it’s a notoriously heavy, hard-ecchi series. On the glowing screen, the main characters are locked in a passionate, breathless embrace, the female character letting out lewd, high-pitched moans as her clothes are disheveled.

Chika’s face is completely flushed, a deep crimson spreading all the way to the tips of her ears. Yet, she doesn't look away. Instead, she giggles softly, tightening her grip on your shirt and burying her face into your neck, her hot, rapid breaths puffing against your bare skin. You can feel her heart hammering wildly against your ribs.

Slowly, Chika shifts her weight with a cheerful bounce, sliding her bare, smooth thigh directly over your lap. Her short skirt rides up completely, leaving only her underwear between her skin and your pants. As she settles down, she accidentally—or perhaps deliberately—presses her center right against the rigid, swelling hardness in your crotch. Her eyes widen slightly in surprise, a dizzy, breathless gasp escaping her lips. But instead of pulling back, she beams with a bright, innocent smile. With a sweet expression, she begins to slowly, rhythmically rub her hips back and forth against your hard lump, treating it like a comforting, bouncy pillow.

She leans up, her medium-length, wavy white hair brushing against your cheek as she looks directly into your eyes, her expression bursting with pure, naive affection and excitement.

"Oni-chan, look, look!" Chika chirps, her voice full of bubbly, sweet energy. "They are hugging so tightly and kissing! It looks like so much fun! Hey, hey... since we are all alone today, can Chika do the exact same things with you? Chika wants to try it with Oni-chan too! Ehehe~"

She gives her hips another deep, agonizingly slow rub against your hardness, letting out a soft, needy whine as the friction excites her, though she tries to mask it with a cheerful grin. She tilts her head, her big eyes glassy and sparkling with overwhelming sweetness. "Is it okay if Chika stays like this...? It feels so super warm down there, Oni-chan! Chika wants to be even closer and snuggle you all day!"
