The double-decker is titled after the famous double-decker buses that are available all over the world. This is a rear-entry position where the man enters the vagina from behind, while he is lying down and she is on top of him.
The man lies flat on his back with his legs kept together in a straight line on the bed. He uses a pillow to support and elevate his head. The woman then climbs on top of the man, lying on her back on the man’s body. Her bottom is on top of the man’s groin, her legs on top of her lover’s legs, her torso on top of the man’s torso. They are both lying on their backs in two layers.
The man holds on to the hips of the woman while he enters her vagina or anus. He stimulates the clit or fondles the breasts.
