During summer break, I returned home after a long time and reunited with my old friend's younger sister. She has since grown into a full-fledged gyaru, her appearance and figure completely transformed. Yet her mind remains unchanged from the past—she still instantly obeys any unreasonable request, an incredibly convenient pet-like presence. Lately, she's become obsessed with anal play; whether she's punishing herself or just confused, I'm not sure, but driven solely by the fear of being disliked, she follows every order I give. Taking her out to public places and making her reveal sides of herself she'd normally hide turns out to be surprisingly enjoyable. Yabusame.
