The premise sounds like the typical hentai plot I know, but I assure you it is nothing but. The whole story is very psychological and character driven. There are revelations as well as shocking surprises that will leave you stunned. Through out Slave Sisters we not only watch the development of Yukari and her younger sister Miku, but also Shunji, the trainer, as well. What appears to be a straight forward relationship is actually quite complicated underneath. Each character has a façade they need to portray to one another, however, behind the façade is the true reality which they must except if they are to move forward; a relationship analogous to a Russian doll perhaps.
At the very center you have Miku, who is still rather young and knows nothing about the debt left to them by her deceased parents. She is rather care-free, happy-go-lucky, and a bit of an airhead. Miku believes that Shunji is her sister’s new fiancé and everything will be fine as they start their new lives in Shunji’s apartment. Then we have Yukari who shields her younger sister from reality and tries to burden everything on her own shoulders. She is mature and well mannered but soon looses herself in lust to Shunji’s skillful ways. Enveloping the two is Shunji who is assign to train the sisters to be sex slaves. He is good at what he does and if all goes well, he’ll be able to retire. But behind his seemingly detached persona we learn that he is quite empathetic towards the two. He gives Yukari a ray of hope and struggles with the demands of the organization. He does what is best for Yukari the only way he knows how. Finally, overshadowing all of them is the secret organization, a soulless dark entity of which there is no escape from. Rich elites show up on TV screens in a dark room, getting head while giving orders which are absolute. Those bastards!
Perhaps one of the shortcomings of Slave Sister is its art and animation. Though, for a series that’s more than a decade old, I really can’t complain. The art and animations look rather simple and there is not a lot of detail that goes into the private parts. However, the character design looks good with realistic proportions. The sex scenes aren’t that extensive but do draw you in with character emotions and artistic expressions. They’re not great is what I’m saying, although I did find it entertaining.
The first episode focuses on Yukari and her sexual training, while the second episode is about Miku’s “loss of innocence”. There are elements of BDSM, piss, and enema play; but very brief. The bulk of the sex scenes are one-on-one vanilla sex with some dildos involved finishing off with some ménage a trois.
The voice acting is an excellent portray of the characters. I recognized the voice of Miku to be none other than Nina, the cat-girl from "Words Worth". She has a very cute and pleasing voice. The BG music really accentuates the sullen mood through out and the music score reminded me of something out of “The Godfathers”.
Overall, I really enjoyed Slave Sisters. If you like your hentai with psychologically driven stories and character development then Slave Sisters is a must watch. Although you might find it difficult to “workout your wrists” to, it will definitely give you an emotional workout with its bittersweet moments… more bitter than sweet perhaps, but good none-the-less.
