It's easy to see why the Grandparents throw a Fuck Fest every year, they are masters at throwing parties and we are all just drooling at their ability to party. This is especially true when they are hosting an orgy and everyone is invited. There is one important thing to remember if you are a parent with a kid at home, don't invite your kid to the orgy if they have a crush on your Grandpa or Mommy. This is because if they end up at the party, it will be awkward for the kid and will probably cause them a lot of fights and problems in school the next day. The Grandparents just want to have fun and celebrate their 50th year of being alive..
