Deep penetration can be achieved with the woman on all fours and her partner kneeling behind her. This position gives both lovers the opportunity to thrust against one another, and the man may also caress his partner's breasts, buttocks and clitoris. Rear entry positions like this one are ideal when both partners are in the mood for vigorous rather than tender lovemaking. A variation is for both partners to stand with the woman bending forward and supporting herself against furniture.
