Scared to Death (1980)

A woman (obvious body double for the character) is seen through a window getting dressed, her breasts and a quick glimpse of her pubic hair are visible.

A humanoid creature attacks several people and sticks its tongue in their mouths, draining them of spinal fluid, some victims are seen bleeding from their mouths, and in one scene, a few people are lying on the ground in a bad shape with a few of the creature's unborn offspring feeding on them through an umbilical cord, no gore or anything graphic is shown.

Mild language only, including a couple of uses of "shit" and "asshole".
