This position allows one of the deepest penetration without the need for a lot of athletic movement or acrobatic styling. It is actually the safer for both partner’s backs. The penetration happens at 90 degrees, which makes this position very good for long cocks:-)
It is also the position used when using a sling which is specifically designed exactly to ensure the maximum pleasure out of this position.

One important trick: if you use a table (or any other surface) make sure the bottom’s ass lays a couple of centimeters out of the surface edge. This will avoid any injuries to the upper parts of the top’s legs.
Plus, this position ensures long thrusts and an easy in and out of the top’s cock (suggestion, try to get out completely and back inside… and see you lover’s reactions). Make sure the table is strong enough to sustain the lateral movement. And put a distance between it and the wall if you want to avoid clashing against it continuously:-)
