--Introduction: Sei Yariman Sisters is one of those straightfoward hentais: there's no plot in it and sex occupies almost the totality of the hentai (well, this is a hentai it the first place, right?). And let's be sincere: hentai trying to have a plot it's almost always a 'failure', and many of them exists just in the sake of NTR, Rape, Gangbang and etc.
So there's no bad/dark/heavy atmosphere in Sei Yariman, far from that; there's not NTR, Rape, violence, Gangbang.... all those hard/bad feelings is NOT presented here. Read the story and you'll see it.
Being a straightforward hentai Sei Yariman depends exclusively to its
sex scenes, the guy and the girls. And it do a great job.
--Story: A (lucky) guy called Kenta moves to his 2 cousins (which are sisters and older than him) house due to school circumstances. The 2 girls are like 2 older sisters to him, well... then... the rest I'll leave to your imagination (not that hard to imagine, though) or you could just watch it (more recommended =P) ^_^
--Characters: [Saki] -> the tanned girl, outgoing, Maki's sisters and Kenta's cousin.
[Maki] -> Saki's sister as hot as Saki and Kenta's cousin. She seems less outgoing than Saki, but she not stays behind Saki when the subject is sex.
[Kenta] -> The lucky guy. He's not selfish, he's not annoying, he's not a bad mood guy, he's not childish, he's not bad, he's not a douchebag, he's not mute/inexpressive, he's not stuck up. What can I say? He's normal but that fits well on the palm of the 2 sisters hand; he do the minimum of his role to be played with. Physically: this is subjective, but for me he's a good-look guy (putting this in numbers: from 1 to 10 he's more or less an 8).
--Art and Animation: It's always good to see a hentai coming from Pink Pineapple. The girls are beautifully done, the colors are vibrant, the animation is well done (not simple nor exaggerated) and the ahegao faces are present in a good level and exciting to see.
--Sound: I have no complains about the sound. The girls's moans are pleasurable to listen, and the guy is not a doll where he just stays in silence during all the sex, he moans as well. What the girls/he say during the sex might not be a first time (some for me were) in a hentai, but it's good and pleasurable to listen, a turn on. There's no opening music. There's no background music during sex scenes. There is just a simple-happy instrumental music at the last minute during the credits.
--Censorship level: medium. There're rare occasions (2 if I'm not mistaken) where the censorship get's heavy when they are afar, but quickly back to the medium level. Nothing to get bothered by.
--Enjoyment: I really enjoyed this hentai. I might have already watched similar scenes, but some scenes seemed to be the first time I was seeing it, which is a good point, and so it really turned me on. The enjoyment factor is a mix of all the other factors (animation, art, sound, characters, sex, what they say during sex and etc).
*EXCLUSiVE POINT*: Sei Yariman is a hentai where we have a TANNED GIRL and which we DO NOT have NTR, Rape, Gangbang, Tentacles, Old Men, Prostituting and etc. Yeah, I have already watched about 335 hentais (from 2010 - 2016 so far - going in decreasing order) and had NEVER seen a hentai which the TANNED GIRL do NOT get involved on those things. A (big) bonus point here S2 ^_^
--Score: Based on my overall enjoyment factor. For the first time I watched it I rated it with a 8/10. Then after a re-watched and after seeing some of my other hentais of my list, my final decision is a 9/10 (my score would be a 8.5 without doubts if MAL had this score). I have a (personal) complain in this hentai that if it had properly happened it would give me a full enjoyment (a second episode would go well to "fix" this complain ^_^).
Anyway, 8.5/10 -> 9/10 in the end.
PS.: Sei Yariman does not have a directly connection to the other related hentais, I mean, characters and stuff. It's just same world from ther others.
