It took me way longer to try and remember what this was a parody of than it did to play the game. (Roomi from Galaxy Fight, for the curious)
It's kind of on the border between Visual Novel and CG, basically it's a short (adult) story involving our red-head protagonist and her doppleganger (who apparently comes with a dick.) Controls are simple enough, just click or press return to advance the text. Censorship is of the creepy lenses flare variety.
