The true allure lies in the curve from a narrow waist to wide hips! Ordinary size just isn't enough! That's why we carefully select models whose waist-hip difference measures at least 30cm! That gap is the very source of eroticism in a woman's ass! Driven by this belief, a die-hard ass fetish shop manager measures the waist, hip, and bust of models at his private studio, then indulges in wildly erotic photo shoots!
