First-timers experience shock and excitement, but by the second time, they're hooked and addicted. Intense vibrations stimulate the entire body, enveloping it in waves of pleasure. This sensation doesn't end after one round—repetition awakens even greater joy. The ecstasy feels like it's shaking your very soul.
