hi, so uh, the other day i came across a gif that showed Kirino and Kuroneko bouncing up and down on those giant rubber balls (i have no idea what's the name) wearing sukumizu... and suddenly... something ero happened. yeah that kinda lit my interest but sadly i can't read kanji so i don't know the title. i only found that it's a psp game. can anyone tell me the title? and if possible, where can i download it? many thanks in advance...
