In this variation on the basic reverse cowgirl, sex position B has his legs back towards A's upper body and is leaning forward towards A's legs.
This variation allows B a lot more control and a great deal of energy to thrust up and down, creating an intense penetration. B can grab onto A's thighs or calves to add to the physical contact and can even move A's lower body a bit in this way.
This variation highlights how this position isn't very intimate, but it allows for a lot of control for B and it also allows for a great deal of movement.
