I know I love to tease my girl. I like to see how many times i can bring her to the brink before she cums. so just watch her close, and back off each time she gets too close. then when you finally let her cum- you could wait say 5 minutes (seems a lot longer to her) make her cum until she is exausted. don't stop till YOU want to.i can pull 15-25 orgasmic peaks from my girl like this- it is awesome-
