The man sits and the woman comes down to sit backward on his penis, supported by the man's       thighs. She tilts forward to reach a balanced position, while letting her body move along the penis. The man holds her by the breasts and caresses them. In this delicate balance, a position of equilibrium can be obtained. The penetration is deep, and offers good amplitude of vertical movement. The woman's      orgasm is more quickly       reached with manual clitoral stimulation.
