I just watched Kiss x Sis OAV Volume 3 ("Episode 2") this morning. It was as usual very entertaining but not something I would masturbate to. (Which is fine by me! I wish there were more ero-romance stories like this one with great animation, cute plot, and no reason to get up from the couch sitting back and relaxing!)
However, it's the weakest of the three OAV episodes in my opinion. The only excitement in this episode revolves around Keita's sexual advances on his sisters / their sexual enticements, with very little in the way of the adorable humor present in the previous two OAV episodes. There are many adorable moments, but few of them are on par with the numerous adorable moments in Episodes 00 and 01.
Then again, I'm not a fan of the fetishes explored in this OAV, so your opinions may be very different from mine. If you're a fan of all things urination, this episode is for you!!
* the girls hold it in, complaining they're about to pee all over the place
* Ako is scolded by Keita and she makes her way to the girls' room, complaining that she's about to leak any second now
* Riko, meanwhile, mentions peeing in the room to Keita
* she mentions plastic bottles, and how she envies boys' ease of peeing into containers, and then mentions she could pee into one if only she had a funnel
* Riko tells Keita to drink her pee (he refuses)
* Keita takes Riko to the girls' room
* Riko tells Keita to take her panties down for her
* Riko wets herself a little as Keita picks her up to take down her panties
* Riko pees while Keita is still in the stall with her
* Riko asks Keita to dry her vagina off
So if you're into any of those things, well, they're all there. To me, though, urination is a 2 out of 5: I dislike it, but I don't hate it. (1 = hate, 2 = dislike, 3 = neutral, 4 = like, 5 = love)
The other half of the episode is the closest Kiss x Sis has ever gotten to a sex scene. Some would even say that this crosses the line and actually is a genuine sex scene.
* Keita gets drunk again.
* He sits Ako on his lap (over his erect dick).
* He removes her clothing over her boobs and fondles them.
* He tugs on her nipples.
* He makes for her vagina ...
* ... but then the phone rings. It's the karaoke manager, and he's telling them that they only have 5 more minutes left before they have to leave (and make way for the next party).
* Ako asks if they can't possibly extend their time, but he mentions he's totally booked due to it being the busy holiday season, so no, he can't.
* Disappointed, she turns around to see that Keita has passed out anyway.
* She is still really, really aroused and mumbles about this to herself on the way out.
* And on the way home, as she starts running from her sister Riko, the friction of her legs rubbing against her clitoris -- coupled with her still-rampant sexual excitation -- has her almost climaxing. The end.
Overall? A 4/5 as far as hentai anime goes, and a 3/5 (or a grade of C or C+) as far as the Kiss x Sis OAV series goes. It was very good, but the weakest episode of the three. Oh well. ^^;
