The Backwards Slide – position #12 of 100 Kamasutra Sex Positions
The man sits on the edge of the bed with his legs hanging down and a cushion behind his back for support. The woman sits astride him and bends her legs so her knees are level with his shoulders. She then carefully leans back and rests her hands on the floor, either side of his feet, to balance.
This position is most suited to a well endowed man.
