Hot Sister Spoils Little Brother in Bunny Outfit | Ai Sayama

After struggling with his grades lately—a fact his beautiful older sister noticed—the younger brother motivated himself by a sweet promise: if he achieved a perfect score on his next exam test series. Driven by this incentive to impress her big sister figure (Ai Sayama), he studied relentlessly. The result? He aced every single test! As promised upon achieving flawless academic performance across the board, His sister agreed to fulfill any request he made. With both parents away for three days of freedom from scrutiny at home school life took an exciting turn. The little brother presented her with a provocative 'slutty bunny' outfit. Though initially hesitant about wearing such revealing attire against her better judgment to keep her promise, she reluctantly accepted. But the demands didn't stop there; he required her to call him 'Master,' perform oral sex on him ('sục cặc'), suckle his cock, pleasure his breasts, and even let him fuck her! The initial compliance quickly dissolved into intense desire. The shame mixed with the thrill of wearing the skimpy bunny costume, coupled with the sheer excitement of acknowledging her little brother as 'Master' and allowing him to dominate her, awakened a deep-seated lust within her. She began actively craving his touch, eager to become his devoted 'slutty bunny.' Even after their parents returned and normalcy resumed, she firmly reiterated that this agreement stands—a perfect score guarantees she will obey any command he issues.
