The first episode is hot. It's a brother/sister who play on the tennis team together and they have a pre-established relationship. There's no set up at all. You just establish the team practicing at "tennis camp", then cut to them having sex in a room. The sex is really hot, really well done, and they do a lot of fun "dirty talk."
WARNING: There is a line at the beginning where the sister says something like "It's okay because we're not blood related." This is usually where I turn off any incest I'm watching because if they're not related then WHAT IS THE POINT??? But the brother immediately replies something like, "You're such a liar" which makes her giggle. I choose to believe he is saying she's lying about them not being blood related. Your mileage may vary, but if you're like me it's worth mentioning.
And, if you're like me, then episode two isn't worth watching. There's a sequence at the beginning where the sister wears some bloomers that show off her camel toe, but that's it. The rest of the second episode is the brother having sex with all the other attractive women on the tennis team. If you're into just plain hentai I'm sure you'll enjoy it, but if you're here for incest like I am don't bother. I just skimmed through it and the sister doesn't show up for any more scenes.
Art style/animation is fantastic. Really slick, gorgeous line art, really crisp colors, very detailed internal shots and breasts. One of those anime that you really wish wasn't so heavily censored... sigh, Japan! The sister's character design is a bit weird I think, but she's still cute. I like that she is aggressive but also begging for it/dirty. There's a bit where they call each other perverts and that's why they're perfect for each other that I really liked. This isn't the little sister that just lies and cries "iyaaaa" the whole time.
Backgrounds are beautiful, voice acting is great, everything was fantastic... except for the fact that only one episode is about incest and that's gonna really hurt the score for me. I feel bad about it because it is a beautiful hentai and I'm sure the other sex scenes will be really hot for you. (I cannot say though, as I honestly just skimmed through to see if the sister reappeared.)
But other than that line about them potentially not being blood-relations, this is a really hot incest anime!
