Let her know you are going to start bringing her down.
Begin to reduce blood flow and engorgement by puttng your hands on her whole labial/genital area with firm pressure. Sandwich her lips between your palm and pull up with the finger(s) inside her.
After the pull up, begin to towel her off. You want to remove lubrication without stroking her skin too much with the cloth of the towel. BLOT, don’t rub! Leave the towel on her genitals and hold your hand on top with firm pressure.
Don’t rush her. Bring her down slowly and let her return from her trance state to a beta brainwave state of awareness.
Acknowledge her, thank her, mention a few things you loved about the date.
