Working at the Futanari Beach Police 3

Eru, the penis police officer, is tasked with a diplomatic mission: to guide and watch over Aria Rena Vandestiny, the princess of an independent duchy, as she tours Inujima's famous nudist beach. The problem is that the princess is completely oblivious to anything sexual, so she keeps rubbing her massive tits all over poor Eru. Since Eru's job is to prevent boners on the beach, this puts her in an awkward situation as she finds it harder and harder not to get one herself. But a certain incident involving a giant penis-shaped jellyfish might just push Eru and the princess('s dicks) closer than expected...
