Crawl
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.
