Many Sonic fans will find this game to be a hentai porn parody, but only if they prefer the personality of Rouge the Bat and Topaz over those of the melancholy supersonic hedgehog, as they serve as the game's primary characters. The plot opens with the villainous scientist Eggman shooting Topaz. Eggman is currently looking into new tentacles on her, and it stands to reason that these studies will also involve a significant number of humps in each of Topaz's holes. Enjoy the contest.
