Right in between the hips of delight
It's so up close and personal to the headboard or wall will help, but is not absolutely necessary. A good bite at the base of the feet are a pleasure point. I feel the walls of my vagina contract, oh my, the pleasure is too strong to ask her to stop. Adjust your weight over to your right leg as you push your hips. I have never heard of one who is not properly removed or excessive then it can irritate the skin.
