This is a great way to find just the right angle to stimulate her G-spot.
Here's What You Need:
Just the two of you.
Here's How You Do It:
Get her naked. You, too.
Have her sit on the edge of the bed with her legs apart.
With you standing, enter her.
Have her bend her knees, letting her feet rest on your stomach.
As you continue thrusting, tell her to "walk" up your chest, placing one foot in front of the other.
As she does this, you'll stimulate different areas of her vagina. It's up to her to determine exactly where she should be on "the wall" to achieve an indescribable orgasm.
