Star☆Jewel Gaiden: Natsumi Oblivion  

Star☆Jewel Special, STAR☆jewel なつみオブリビオン

The goddesses of dark and light are engaged in a conflict over jewels that innocent women possess. While those who worship darkness attempt to steal these treasures, leaving lifeless husks in their wake, the followers of light seek out evildoers. Both sides have powers for battle, but their strongest weapons are retractable penises which they use to flood enemies with pleasure as a means of victory.
