Firmly planted in the vaginal opening, the man leans over to one side. He leans either on left knee and left palm or on right knee and right palm. The man's position offers him the possibility of performing come-and-go movements as well as circular ones. The woman won't stay passive, but will answer with soft movements of the pelvis, as a response to the ones of the man.
In this position the man provides the woman with an extraordinary massage of her G-spot. Very few women can resist such a stimulation without having a profound orgasm.
The man can insert and withdraw his member as he sees fit, slapping gently her thighs and buttocks.
