My Tsundere Little Sister [250821][RJ01451966]

While our parents were away on business, my sister and I were left alone in the vast mansion.
The quiet mansion gradually filled with a sweet yet dangerous atmosphere.
Even my sister, who was usually cold toward me, showed a different side of herself on those nights alone together.
I would gaze at her adorable sleeping form, wrapped in loose pajamas. The soft curve of her chest peeking out from the hem of her pajamas, her smooth white skin—everything about her sent my heart racing.
Each time I felt her sweet, vulnerable breath, the forbidden desire I had suppressed deep within my heart stirred.
“I can’t take it anymore…”
Overwhelmed by uncontrollable feelings, I finally broke the taboo of incest and resolved to claim my sister as my own. However, during this summer vacation, it’s not only my sister, but also the attractive girls around me who seem to harbor secret feelings for me. Can I suppress the throbbing of my sinful heart during this one-month cohabitation?
The period is just one month. The forbidden sibling cohabitation begins now.
