Perfect set up. They both like the guy and pose for a picture. One jokely says to the other "move over a bit." They have their fingers intertwined so their palms press together as the blonde pushes the brunette who almost falls off the little bench. The brunette pushes back bringing them into a mutual contest of strength. Each pushes harder bringing their breasts together as each strains. They begin to bicker as each makes eye contact. Then, they notice that the guy they are both crushing on is getting excited by watching this. They forget the photo shoot and stand up continuing the test of strength until the brunette lets go of her grip and grabes some blonde hair. The blonde does the same and he watches as both lovely young women begin to grunt, sqeal and move about the boat eventually falling onto it's deck in a full fledged catball catfight. Tops come off and eventually the blonde over powers the brunette just due to her extra body size. By this time the guy who owns the boat and was taking the pictures is fully tented. The blonde looks over at him from on top of her beaten foe and after examining his hightened "soldier" she looks into his eyes and says " I can show you something you should do with that thing."
