The Doggie Style Strap allows for deeper penetration and g-spot stimulation, and increases the angles of penetration from 90 degrees to 45 degrees. Instead of grabbing on to her waist, he holds on to the handles for motion control and thrust assistance. The wide padded part that rests across her pelvis provides extra support, and also compresses the pelvic wall. This compression lets him provide the extra contact and friction to her g-spot.
