An acronym, ARIA stands for (well, besides hot sex) Advanced Rogue Intelligence Assault. In the game, there are four gorgeous hentai babes that are members of the galactic police who are tasked with a most difficult and dangerous mission - locate, subdue, and arrest a rogue captain - bringing him back alive. Naively, they think that it'll be an easy job, but they'll soon end up finding out that it will be anything but. For whatever reason, they assumed they could more or less just walk in and capture him without a fight, but he's not going to go down that easily. That's when they hatch a plan - they know they're all very sexy, and that they're highly skilled at sex - so maybe they can get him to fuck them, and then capture him while he has his guard down. You can definitely expect to see lots of blowjobs, sexy, and nasty orgies where these babes take on multiple cocks and do it with big smiles spread across their faces.
