In the Sitting Bull position the giver sits on a bed or other service with their legs open, and has their partner lying on their back with their legs over the giver's shoulders. It is quite an awkward position to get into, so the easiest way to get into it is by having the receiver lay down backwards from a kneeling position and then swing their legs up-and-over. Although a fairly comfortable position for both partners, it does lack in mobility for penetration.
