Admiral is sick and it’s Suzuya’s job to pamper and nurse him back to health. But being delirious, he starts sucking her, so then she starts sucking him, then she straddles and things that do not lead to his quick recovery start happening.

In addition to that short story, this doujin also collects three copy books that the author previously released on events. That’s 30 extra pages of roughly illustrated sexy time with Suzuya, Haruna and Kashima.
