The vibrator with a timer program is fixed onto the girl's sensitive spot, delivering continuous vibrations with intervals of one to two minutes, gradually increasing in duration. At first, she feels unsatisfied, but as the vibration time lengthens, she slowly becomes unable to endure it. Five minutes, six minutes... ten minutes... As time passes, the girl is driven to her limits, completely overwhelmed by the escalating waves of pleasure. Watch as the sensitive, impatient older sister Momoka loses control in a panic from sheer overstimulation, captured by a fixed camera in this intense, newly-staged production!
