It's pretty weird. It starts with a girl called Menou talking to a video camera.

"Okay! Huh, a little bit to the left? Is this all right? Okay, thank you! Ahem... I'm talking to you from somewhere deep within your usual dream world. This is a place called Deep Stratum. This isn't an isolated place in your dreams, but a realm that everyone can collectively access. Once, it was a paradise. Nobody remembers any more, but that used to be true. We've restored this very same paradise and we've decided to invite all of you here. The residents of this town are qualified to be here. I'm sure you'll all like it in here too! We worked hard for this, after all! Mind you, most of you will probably forget about this dream when you wake up."

The rest of the story alternates between:

(a) dream scenes of our heroine performing sex acts on men she doesn't know.

(b) friendly, everyday slice-of-life scenes with two girls and two boys. Yoru and her sister Asahi run a cafe, while Shirou and Kouhei help out. Nothing hentai about any of this. They're all friendly and likeable... except that Asahi has "customers" on her "night job". This isn't what you're thinking.

"That's what people haunted by sex demons look like. My sister and I both do this job to save the people they possess. We enter their dreams and get rid of those sex demons."

It's based on a game, but it's a lot more odd and interesting than most game adaptations. There's a plot and it's pretty unpredictable.

The episode opens with the heroine, Rinne, having already been captured by the baddie. He's raised a force field around the island and she can't use her powers!

After some preamble, the rest of the episode is just Rinne and her sisters getting gang-banged. She isn't even allowed to use a toilet. It's based on a visual novel, i.e. pornographic computer game, but the evidence of these episodes doesn't suggest that the original had much plot.

It lost me in about forty seconds. Our nude, pink-haired heroine (Nagisa) is shagging a yakuza, which is an unusual way to open these TV hentai. They usually build up to the sex scene instead of showing everything immediately. The rest of the episode is then a flashback, building up to it.

"I don't believe he's a bad person," thinks Nagisa.

Nope, sorry. She's thinking with her hormones. He's a gangster, with the tattoos to prove it. He lives off organised crime. Piss off. Not interested. (For what it's worth, Nagisa went on a trip to try to change herself, especially the fact that she's 26 years old and yet still a virgin. Well, she's solved the latter problem.)

It's set in a fantasy world where sex affects your mana (which makes sense) and so society needs doctors who can use sexual techniques to heal their patients' physical and magical afflictions. Our heroine is one such doctor. She doesn't hide her profession from her husband (whose physical condition stops him from satisfying her sexually) and they love each other, but she has at least given herself a rule of "no actual sex with patients". Mouth, hand and boobs only.

Patient #1 lost all his power when his wife died.

"Don't worry. If it's possible to trigger, I'm sure you'll recover."

"Trigger?" (She unzips him.) "Doctor!" (She gets her tits out.)

"Instead of just your genitals, let's stimulate your whole body next." She then advises him against getting too aroused... while masturbating him and pressing her naked breasts against his chest. This is not a relaxing activity. "Calm down and relax," she says nonetheless.

Afterwards, it seems to have worked. "I feel like I'll be able to use magic again the way I used to!"

"You're still far from full recovery, so please keep visiting for more treatment."

Patient #2 is a young lad who we saw fleeing when propositioned by a prostitute (except that she called her job "healing"). Even multiple ejaculations don't stop mana from accumulating in his penis, instead of circulating through his body. Our heroine does her best to help, but eventually realises that her regular treatments aren't doing the job. Is full sex required, then? (She also sees him shagging that prostitute in a back alley and observes that "ejaculations aren't enough; mere superficial attraction won't make that boy an adult.")

"I have to do it."

It's terribly civilised and professional. If mana existed and people had this kind of problem, I could imagine the outcome being treatment like this.

It's an anthology series of pornographic versions of famous children's stories. There's a framing story to explain why this is happening, but this isn't very important and basically means that an evil reader can rewrite the plot as he hops from character to character. "This is an enchanted book of fairy tales. The reader can freely change the stories in it."

Little Red Riding Hood (whose real name is Blanchette) is an idiot. A wolf walks up to her. Big, hairy, looks like a dog, wants to kill her and devour her flesh, etc. "Are you a wolf?" asks Blanchette. Yes, I laughed.

"I was actually a prince from a kingdom far far away," replies the wolf, lying through his teeth. "But due to a witch's curse, oh, I turned into a wolf!"

Blanchette believes him. "Can I do anything to help you, Mr Wolf?" A few seconds later, his manhood is between her naked breasts. "Will this be enough to break the curse?"

"Of course it will! Now, move those boobies!"

"I'll definitely save you, Mr Wolf!" Then, later, "Uhh... wh-what is this white stuff?"

Things get sinister and rapey (although Blanchette isn't even shocked), but what happens next is downright weird. The wolf eats her. She's inside his stomach (which is a lot bigger than you'd think) and she's being attacked by some kind of stomach digestive cell that's pretty much her own size. "Are you going to digest me?"

She then gets rescued by a hunter who killed the wolf and cut Blanchette out of his stomach... but the hunter is that evil reader because he's been body-hopping again. "Mister, why are you touching my breasts?" Another peculiarity of this episode is that Blanchette thinks wolves can get humans pregnant. (Well, this is a fairy tale and the wolf can talk, so...)

This one's a lot stranger and far less pornographic than you'd assume. (There are quite a few pornographic versions of Alice in Wonderland and this one could almost be called tame. When Alice grows huge, for instance, she doesn't explode out of her clothes.) Much of the episode is simply playing with Lewis Carroll's ideas. The Cheshire Cat does nothing sexual at all, but instead tells Alice to go to the palace and win a game of croquet. The playing cards applauding the guilty verdict at Alice's trial are somewhat disconcerting.

Alice mostly has sex with creatures, being more enthusiastic about it than Blanchette was. She does a caterpillar, a pig (ish) and a gryphon.

"For destroying the royal palace by using a growth potion, for the theft of the duchess's pig ingredient and, lastly, for ignoring the king's orders and engaging in indecent acts with the Gryphon, the defendant Alice has been found guilty!"

It's ambitious, for hentai. You could mistake it for a proper drama with a reasonably rich cast, including nice people who don't deserve any of this. (It's based on a visual novel, which explains a lot since that genre is basically multiple-choice novels. Well, the good ones are, anyway.)

An island resort is being opened. A lot of people worked hard to make this happen, including a toad-like man who looks like Donald Trump. "I have no further need for a filthy man like you," says his ruthless lady boss. "You're fired today."

"I knew that already," says Trump. He's got an assassin with big boobs hiding in the roof.

Before long, the hentai action begins. Vines come through the windows, attack people and carry them into the sky. They also spit fluid on you. No, not like that. It's transparent, like slime or water... and it eats clothes. These vines are naughty hentai tentacles, of course, and there also are red tentacles which turn men into sex zombies.

The plotting then becomes a lot more rudimentary.
