Hunky young medical student Johnny Castle rents a room from hot Chilean cougar Tara Holiday. Tara's son Seth warns Johnny that Tara loves to "play mommy," which only serves to turn on the maternally-neglected young man. Then Seth meets Johnny's mom, hot "party MILF" Veronica Avluv. Can the two studs satisfy their needs by swapping moms? Meanwhile, Erica Lauren and Nina Hartley have grown sons who are lifelong friends. Erica's son Richie Deville comes to visit after spending time with his long-lost father in Spain and upsets his mother with his disrespectful new attitude. Nina takes Richie's side, and when Erica storms off to her bedroom, Nina's hot son Michael goes to "console" her. Richie confides in Nina that while in Spain he discovered the pleasures of sex with "much older women." Perhaps a little "mom-swapping" is what these oversexed young studs need.
