WARNING: This doujin contains puke and scat.
Mizuho and Kashima clash in front of the Admiral’s office about who’ll serve him lunch. After sparks start flying, Ooyodo intervenes and proposes a way to resolve the conflict: the two ship girls will compete to determine who’s a bigger pervert. Winner will get to serve the admiral. Flawless logic.
So with a group of burly seamen assembled, the lewd-down can begin!
