After experiencing her first sexual encounter, Shiori Aiochi has rapidly transformed into a mature, sensual woman. Her body has become incredibly sensitive, reacting intensely to even the slightest stimulation. When her vagina is vigorously stimulated, her body helplessly gushes out lewd fluids, and the pleasure grows stronger and stronger, making her squirt like a fountain. During her first threesome, her body reacts so intensely that she loses control of her bladder every time a cock is pulled out. Shiori's incontinence is unstoppable... Her hypersensitive body is being pulled deeper and deeper into an erotic world.
