[Hiroki Ishikawa] SOUKAI NO HERO KAIZOKU 1 (navel fetish pirates)

A drowning man with one shameful secret gets washed ashore onto a pirate ship where his obsession becomes his profession. Dubbed the ship's official 'navel inspector,' he plunges fingers into every sensitive belly button on board, driving a curvy blonde crewmate to ahegao-faced bliss as she begs him to push deeper before their navel play erupts into full-blown sex. Between the buxom captain demanding reports, a sunbathing crewmate, and his cry to become the Navel King, this is one fetish-fueled voyage across the high seas.
