In this erotic tale, we follow the story of Seto Yuhi, a seemingly innocent and quiet girl whose younger sister, Yui-chan, catches her off guard with her unexpected sexual desires. It all starts when Seto helps her sister study by sneaking touches under the guise of tutoring. Soon enough, they can't resist each other any longer, and their passionate encounter leads them down a path filled with taboo pleasures. Despite feeling guilty about taking advantage of her sleeping sister, Seto cannot help but become increasingly aroused by every touch and caress. As if possessed by some unquenchable lust, she continues to penetrate her helpless sibling despite multiple orgasms. Finally, exhausted yet still hungry for more pleasure, they fall asleep together – only to wake up later engaged in another round of steamy anal play followed by rough cowgirl position sex that leaves both girls satisfied beyond belief! Little did Seto know that beneath her sister's gentle exterior lay a hidden wildcat ready to pounce on anyone brave enough to cross its path... or should we say, enter its bedroom?
