Shimakaze spends some time at the base's hangar in order to try out some new ammunition for their future missions~! After a brief set of stretches and exercises they prepare their asshole with their lubed up fingers and eventually their fist~! The first ammunition they get to test out is some explosive anal beads which very quickly fills them up to capacity. The second test, a large caliber round, is much more fitting for the type of battleship that Shimakaze is and it shows~! They quickly take to that type of ammunition and is able to take the stress testing to completion~!
