The T-Position for pegging requires the receiver to lay on their back with their legs drawn up. The giver is perpendicular, on their side, forming the top of the T, so to speak. The Salto Slingback can help the receiver keep their legs up effortlessly!
Speaking of effortless, this is an excellent position for big beautiful bodies. Both partners can be lying down, and the lovely large belly of the giver won't interfere with penetration, especially if you have a longer dildo (a must have for lovely large bodies!). The receiver's cock is accessible by either partner and eye contact is possible, too!
