FLASH BACK 3 Studio: NuTech Digital Run Time: 26.05 Director: who knows Extras: Photo Galleries , Trailers Date Made: 2002 Video: 4:3 Cast: voices of Ava Vincent , Aurora Snow Audio: Dolby Digital 2.0 Type: hentai ( anime ) Region: 0 (all) , NTSC Condoms: 0/4 scenes Lingere: 1/4 scenes The Story The final part of a trilogy called Flashback , this Hentai's main selling point is in the use of real porn stars voicing some of the characters . Whether or not that's a particular turn on will have to be up to you . The story revolves around three girls ( Mizuho , Yuri , Noriko ) who are undergoing experiments which reveal their innermost sexual desires . Each sexual encounter is referred to as a 'treatment' , and they appear to sometimes take place in reality and occasionally in the girls' subconscious . Believe me , that sounds a lot more interesting than the finished product .
