This doujinshi is based on fanwork that is well known oh the internet. They design mascots for operating systems and programs. Right here we have WindowsXP and 2K but there are others as well such as DOS, Norton or Google.
There is nothing much in the story. Just that 2K played with XP during their master absence.XP is embarrassed at first but gradually enjoy after a while. The art is quiet good, though I feel that XP is a little too fat.
This doujinshi could be enjoyable but the fact that XP just masturbated and gave 2K a blow job is somehow leave me unsatisfied.

You know the drill about OS-Tans, operating systems drawn as cute anime girls. They've since become a staple of *chan image boards, so you should be interested in this one if you like your OS a little too much, or just like generally good looking girls.

The doujin itself is generaly well drawn, and there's some nice big busts, some nice XP masturbation and a decent blowjob.

It's mainly a yurifuta with 2K and XP, 2k being featured as a dick-girl. There's some good shots of XP-Tan in here, the only 2K nudity is pretty much bellow the waist shots of her dickgirl penis.

A pretty short doujin, nothing too special, but all around well drawn, especially if you're a fan of XP-tan or futanari-2000.

I don't think I can give a detailed review as the first two did but I'll try. They made the XP girl a bit fat but i've never been a fan of anorexic women. She's not that fat but not too skinny either.

In the beginning, some guy is leaving her residence in which she lives with the 2k girl. It turns out XP had a dildo up herself the whole time and she masturbates and eventually gives 2k who turns out to have a weenie, a blowjob. It's a short doujinshi with so-so art. Don't expect too much.

Waste of time to download if you're trying to fap but a nice addition to anyone's hentai collection.
