Joey looks up from the gun just in time to see a deluge of water coming from Ayumi. The stream hit him in the chest and sent him flying backwards into the sand, where he lay, unable to move.
From his viewpoint on the sand, he watched as Ayumi ducked a stream sent from Kylie, hitting her in the head with a return shot. Whirling about with astounding speed, Ayumi dove sideways out of the path of Joanne's shot, returning fire in midair to sweep across Joanne from head to toe. Finally, she stood, facing Alexis, at a standoff; each waiting for the other to make the first move.
It was during this standoff that Joey had time to truly admire their bodies. Ayumi was extremely petite, probably not even five feet tall, but with relatively huge breasts. If he had to guess, Joey would say they were at least D-cups, with a significant amount of cleavage showing through her tank top. Her butt was extremely pert, quite possibly the perfect example of what the people who came up with the term 'bubble butt' were thinking of. Alexis was taller, by about half a foot, with E-cup breasts on display in a tight-fitting bikini. Her body was rock solid, clearly she spent a lot of time working out.
Then, almost too fast for his eyes to track, Alexis fires, Ayumi ducks, Alexis dives to her right as Ayumi, predicting her movement, leads her and hits her full-on in the face with a stream of water.
All of the girls besides Ayumi were now paralyzed similar to Joey. Ayumi looks at Joey and strolls towards him. Joey tried his best to keep his eyes from wandering, but her body was just so beautiful that he couldn't restrain himself. He felt his cock growing hard, tenting his swim trunks quite visibly.
Ayumi stands next to Joey, then proceeds to straddle him, grinding against his rock-hard cock. Joey looked up at her beautiful Asian face as he felt the pressure begin to build. Then he notices that she was fiddling with her soaker pistol, switching her dial to some other setting. As his pleasure continues to build, she points the pistol at him and blasts him again.
