Emma Starletto and Natalie Brooks think it is hilarious that their grandpas would rather rest and relax than swim when they are by the pool. To play a trick on them, they take some sunscreen and write old fart on one of their stomachs, and cannot help but laugh. That sends these two old studs into action. They find their grand playing with a beach ball naked in the pool, and decide to teach them a lesson. Evan Stone and Filthy Rich come by and cock feeding Natalie and Emma by the pool.
