To perform the pinball wizard position the partner that is going to be penetrated needs to get into a bridge position. This involves lying on your back and then raising your lower body off the floor with your legs flat on the ground. The penetrating partner then positions themselves between their partners legs kneeling upright. They can enter them from this position whilst holding onto their partners legs for support.
The pinball wizard is great for deep penetration but does require good core strength from the partner that is being penetrated. This position is perfect for stimulating the clitoris during penetration as it allows for easy access.
For even deeper penetration the partner that is being penetrated can lift one leg up and rest it on their partners shoulder. To perform pinball wizard doggy style the partner that is being penetrated simply flips over so they now facing away from their partner. The penetrating partner can grab onto their partners waist to aid thrusting. This is also a very deep penetration position.
