Akita doesn't notice two invaders have just entered the area. Being on an empty stomach doesn't help his senses. Too occupied with retrieving Dragox from his cock his back is turned to the pond. He licks himself into arousal and suckles until the pressure is built. When that happens the testicles release their content into the prostate which expands to accomodate the juice. The pressure mounts more and more until it reaches its upper limit. At that point the prostate contracts forcing everything it's got into the shaft.
