Story Introduction
Left behind in the vast mansion while our parents are away on a business trip are just me and my younger sister.
Within the silent halls, a sweet and dangerous atmosphere gradually begins to pervade.
Even though she’s usually aloof towards me, she shows a different side of herself on nights when we’re alone.
Her adorable sleeping figure wrapped in loose pajamas. The soft chest peeking out from the hem and her smooth, white skin—all of it shakes my heart violently.

With every touch of her defenseless, sweet breath, the forbidden desire I had suppressed deep in my heart begins to throb faintly.

“I can’t hold back anymore…”

My uncontrollable emotions surge, and I finally resolve to break the taboo between siblings and color my sister with my own hues. However, it seems that during this summer vacation, not only my sister but also other attractive girls around me harbor secret feelings for me. A limited one-month cohabitation—will I be able to suppress the heart-pounding excitement tinged with decadence?

The period is just one month. The forbidden sibling cohabitation life begins now—♡
