This wasn't really what I expected. Was it bad? Not really, but also not entirely good.

What I expected was a sci-fi story, where it's normal to have sex with robots or own sex-robots. Maybe Akane couldn't get around a partner irl or wants to practice or whatever, and then has sex with that android. 

Well, that kinda does happen but also not. Apparently, it's very illegal to own a sex-robot. Why? Isn't explained. 
It does play in the future, but also not very far, as there aren't any human-like robots on the market (or, well, there are, but again very illegal) and Akane is surprised by the ai level of her robot, even though she works in robotics.

Akane also didn't want to have sex with a robot. She actually wanted to buy a maid-robot, but because she has a bad drinking habit and can't control her alcohol addiction, she somehow ended up buying this very illegal sex-robot with more than maid-services. There's a whole mystery around it, as the website, where she bought it, isn't loading anymore and she can't track her order back. She also doesn't remember paying 5,000 Yen for it. 

The premise surely is interesting, and I didn't expect there to be that much mystery around it.
Though, while the interesting storyline serves as an argument for anyone who says this is just another "porn without plot" manga, and that is true, the author does focus much more on the sex scenes and only occasionally continues the story.

The sexual scenes sure are a bit different (sometimes) from "normal" mangas. For example, Nadeshiko goes to sleep-mode at night, and the only way to wake her up, is by giving her a kiss with tongue – because the turn-switch is inside the mouth, but if you reach with your fingers inside, you might damage something. Or, in order to register and use the robot's services to the fullest, you need to insert your fingers into her vagina, which will save the owner's fingerprint and register in the database. Because Akane refuses to do that (mostly bc of the legal issues), Nadeshiko labels her as a hopeless bottom and thinks Akane just needs to warm up to her more until they can go "deeper". 
As absurd as that sounds, it also kinda works. The whole story is more comedy than romance/love, nothing meant to be taken seriously.

And while that part surely makes it stand out from other erotic mangas, the other parts during the sex scenes don't. Every sexual act between them basically starts the same: Akane doesn't want to, refuses to let go of that last bit of human pride she has, but also because she doesn't want Nadeshiko to win and make Akane fully registered (– seriously, either Nadeshiko is completely innocent and was only programmed to make her owner register asap, or Nadeshiko is even more human-like than we thought and might fr love Akane. Whatever is in it for her once Akane registers...). But Nadeshiko never listens to Akane, and touches her until Akane gives in to the horny feeling. 
Sometimes it stops in the middle, with Akane realizing what Nadeshiko is plotting – and, again, everything about the technical/robotic parts make it interesting –, but overall it's not that amazing.

While it's also funny, how Nadeshiko takes literally everything in a sexual way, it's also a bit tiring after some time. Sure, she's a robot, so despite being very human-like, she does need to have some robotic features as well. But that aspect leads us back to "porn without plot". And Akane at some point gives up trying to respond normally or start a conversation, because *everything* turns sexual in Nadeshiko's mind. 

If you're looking for some fun and kinda different erotic manga – and not anything "ground-breaking" –, then, sure, why not. Give it a go.
I too will check out the other volumes, simply because I want to know the mystery around it.
