[Circle Mizusane (Mizusane)] Girls' Photography Club and the Uncle Instructor 4 [Project Valvrein]

Tomboyish photography prodigy Saotome-san has just won her school's top prize, catching the eye of her bearded, bespectacled instructor—a thickly-endowed gym teacher who offers to "train" her in the art of the human form. What begins as a perverse pose study in bloomers and gym clothes quickly escalates as the studious, short-haired beauty is coaxed out of her uniform and taken across his lap, her shy blush giving way to breathless compliance as she discovers exactly what kind of tutoring he has in mind.
