She wants you to turn you brain off, sit with your legs wild opened and tickle her in all the possible way. Slowly rubbing with your fingers, with a slow mode vibrator, using a makeup brush, just pinching her or slapping her. She wants to be wet, she wants to be leaking all that horny juice she's building while you're not touching her. Let her takes control. The wetter and desperate you get, the better you feel good.

Don't cum. Never.
