Christmas Eve is finally here, and buddies Oz Daddy and Matt Stiel have the perfect plan: sitting by the fire with their stepsons, Dex Devall and Nicholas Michaels, and sharing funny stories from Christmases past. While planning the whole evening, they suddenly remember a fun game to play with their boys from their college years. It’s a straightforward “Guess the Drink Challenge” with a special ingredient: their own cum! The guys get down to business and start jerking off to get all set up for the game, but they are suddenly interrupted by Dex and Nicholas. Instead of calling it off, Oz and Matt tell their stepsons about their college tradition and enlist their help to prepare the cumnog. Soon, the preparations for the event turn into a wild fuck session, as the stepdads pass down their “holiday traditions” to the next generation of twinks, with a celebratory cumnog toast to end the night on a creamy note.
