Play with her pussy.

You lie down on the bed next to her and start tracing the details of Amber's vagina with your finger while you stroke yourself with your free hand. Your fingers slowly carve more into the folds of her labia before arriving at her hole. You slowly slide on finger in taking your time to not wake her. You gently begin feeling your way around her inside focusing on her gspot. You feel her pussy become more and more wet.

The pressure in your balls is becoming unbearable.
