A nosy mother-in-law, Cory Chase, urges her stepson, Codey Steele, and his expectant spouse, Laney Grey, to sign up for prenatal courses. It's obvious that both Codey and Laney feel Cory is interfering but the message does not penetrate Rory’s thick skull. Cory insists on imparting some moves from her past experiences taking identical classes.
Laney gets irked by Cory's interference but begrudgingly agrees. Showing massage tips, Cory brusquely pushes Laney aside to demonstrate with Codey. Positioning herself snugly between his legs, Codey cautiously obeys Cory's guidance by strongly rubbing her as directed.
This quickly ignites unexpected tension. Laney is not fooled, sensing jealousy creeping in she vies for Codey’s focus unsuccesfully. Frustrated, Laney storms out, abandoning Codey and Cory in private.
The abandoned pair succumb to mutual passion telling themselves they are merely preparing Codey to tend properly to Laney. Nevertheless, driven by desire and impulse the duo transcends the point of no return.
