Barbara is seen in her bra and panties in one scene.
Lorissa McComas rides a guy in the back of a pickup truck. You can see her breasts and part of her pubic region. This can be seen on the original DVD version and lasts for over 8 minutes. The versions found on streaming services (Prime/Tubi) are as described below, severely edited.
There is a shorter scene where we only see just a few seconds of the sex scene. No thrusting, just the nudity.
