Jack Vegas and his stepdaughter Jane Rogers are hanging out with Mike Mancini and his stepdaughter Tristan Summers; the girls are learning a lesson from their stepdads on how to play baseball. When Jack and Jane take a break, Mike and Tristan find them doing inappropriate things in the kitchen; at first they are surprised by it but pretty soon they both get turned on too. The stepdads decide to swap the girls and teach them a different lesson, one that involves some good sucking and fucking.
