When it feels like she is at the boiling point and can’t stand it any longer, when she seems eager to have you enter her, try rubbing your penis on her clitoris and then slowly, inch by inch, move your penis inside her. Don’t rush into full-force thrusting. Tease her a little, pull back, and see how she responds. If she is thrusting against you or her legs are wrapping around your back, she wants you to go deeper. Remember anticipation. Tease her. Tempt her. She will go crazy when you actually do thrust fully inside her.
