It's absurd and revolting, but its absurdity's crazy depths are almost impressive.

Girls are horrible to each other (e.g. using a clothes peg on a classmate's skirt to reveal her knickers), but it turns out that their apparently nice teacher has been manipulating the situation to his own intended advantage. He has footage of one of his pupils masturbating in the classroom against the edge of her desk... hang on, no, wait. In the classroom? Sexually aroused by a desk? And exactly how did he take this footage without her noticing? An invisible robot drone?

The teacher blackmails the pervert with the footage and she's shocked. Presumably she thought her school classroom was a private space where you can commit any obscenity with no risk of being discovered. The really weird bit, though, is the teacher's plan. "It's not you I'm after. I want Yua-kun. I wanna have her. And I want your help with that."

I'm pretty sure most schoolgirls wouldn't shag their teachers merely because a classmate suggested doing so.

The characterisation of the girls in the early scenes was quite good. "Did something specific trigger her?" "I'm not sure. She suddenly went like that." There's also deadpan gross sexual comedy. ("Hold out your hand." She does so. He puts his penis in it.) Basically, though, it's unpleasant and disgusting.

It's nice. Everyone means well and no one gets two-timed. The hentai dangles this as a possibility when another girl shows up halfway through and takes our hero drinking, but nothing happens and she harmlessly escorts him home to his girlfriend.

Our hero is Kobayashi Yuuichi. It's his girlfriend's birthday, but she's dumped him within the episode's first minute. "Yuuichi, I'm sorry, but let's break up. Sorry for keeping this from you until now, but I started dating someone else without telling you."

Kobayashi has a junior at work, Tsujinaka Miho, who immediately invites him out drinking. Within another two minutes, she's offered to become his replacement girlfriend. Two minutes after that, she's dragged him to a love hotel and has his dick out while confessing that she's always fancied him but had always held herself back because he was attached. This one's nice. Mostly sex scenes, admittedly, but romantic ones. No one does anything bad and occasionally the episode's even amusing, e.g. the byplay when Girl 2 (Nakamura Shiori) escorts Kobayashi home to Tsujinaka.

If you're looking for absurdity, look no further. Common sense (and of course common decency) are being twisted out of recognition. These girls aren't human. Let's start with the premise.

"Could you get all the girls on the island pregnant?"

"The village leader explained to me about the old customs of this island and a certain problem. [...] A woman with high potential can give birth to lots of children. A high quality female has sex with many men from the village. After that, when a girl is born, the whole town educates her in being a good female. The girl gets approved by the village chief and the men start planting their seeds. Girls of better quality attract more men. If a woman gives birth to a boy, she's considered to be of better quality. The women of this island have done it this way for hundreds of years. Thus her external and internal attractiveness as a girl took a qualitative leap."

...instead of, say, dropping like a stone from inbreeding. Also, the sexism is jarring even for porn. However, the island's women have stopped getting pregnant.

"I did a lot of research, but the conclusion is that it's genetic. It seems that the younger islanders have reached their genetic limit. We're in crisis on the island. If we don't do something about it, we'll cease to exist. We need the help of men from outside the island."

What's a genetic limit? You might think the genetic stock has deteriorated due to incest, but it's weirder than that. These girls' deep throat goes so deep that the tip must be almost touching the back of the inside of their skulls. They can also get pregnant and give birth within 24 hours.

"I think I can give birth today." WHAT THE HELL? She's huge.

In other words, it's nonsense with terrifying physiology (including their bust sizes) and girls who'll marry you while still encouraging you to shag everyone else on the island. "It's okay for you to get lots more girls pregnant." There's also, though, a little sister who disapproves of all this and thinks the islands' customs are a violation of women's dignity... and yet she has this scene on finding him asleep:

"Is he sleeping like that? This is my chance to prove that it's something harmful. The selfish penis that turns women into useless and worthless creatures. He hasn't woken up. I'll keep inspecting it. Oh no, what's this? I knew it! It's harmful!" (She starts sucking him off.) "This is something bad that corrupts and ruins people. I will not give in, because I'm a woman!" (She continues.)

Even for hentai, it's mental.

For five minutes, it's an ordinary school anime with likeable characters and almost nothing to suggest hentai. However, the title means "Impregnation Club" and so this high school does indeed have an after-school club for getting its schoolgirls pregnant. They have surprisingly relaxed club policies. I'm surprised they got that past the PTA.

Our protagonists are: 1. a short boy called Sudou who needs to give his club documents to a teacher, 2. a red-headed girl called Umi Touno who treats him coldly and only ever calls him "otaku" rather than his name, and 3. her nicer blonde friend Aika Asagi who'd like his help with English homework. This is a charming, romantic story of:

(a) a girl who likes a boy and will eventually explain that she's always liked him, but had been too awkward to say so.

(b) another girl who sits by the bed and makes encouraging comments while watching her friends have sex. Maybe she's waiting her turn, but that won't happen this episode.

AIKA: "Umi has been practicing blow jobs so she can pleasure you."

UMI: "Aika..."

AIKA: "Yeah, understood, I'll shut up now."

"Practicing"? On who or what? Well, never mind.

(c) an official "get girls pregnant" after-school club that conducts its business openly and is regarded by everyone as a normal school activity. High school girls join it. The club's activities are monitored by the teacher in charge... and I'm not talking metaphorically. She has closed-circuit TV cameras that lets her watch and record video footage of her students' sexual activities. She masturbates to it. I'm also not convinced that the club's rules don't contradict each other. On the one hand...

"I need to pick a partner in my trial membership period!?"

"That's right, and she'll be your lifetime partner."

On the other hand, two girls have chosen Touno as their secret crush. "Are you okay with alternating with them as partners in club activities?" asks the teacher. Is there a trial membership period during which polygamy is encouraged and you don't have to choose?

Everyone's nice and consensual. The music's gentle. You could call it romantic if you don't mind triangles. The teacher and her school policies are freaky as hell, though.

That teacher also shows sex videos of herself to Touno. She calls them "Sexual Education Videos", but surprisingly never jumps on him herself.

"Today's my first day of practice with Asagi-san." As before, both girls are in the room throughout, but Umi doesn't sit there watching as closely as Aika did.

Touno gets an education in where the G-spot is, but I'm pretty sure the creators of this anime don't have a clue where it is or what to do with it. Also, it would seem that daily sex is a club requirement and you need the teacher's permission to take a break from it. Yeah, it's bonkers (and the ending's a cheat).

"I gave you the day off from club activities yesterday to think. Have you reached an answer?"

Ninjas with big boobs get captured by the enemy every time they go out on a mission. Her captors will give her aphrodisiacs, then get down to (hentai) business. Sometimes one brainwashed ninja will even help the villain capture another of her former colleagues.

These ninja aren't very good at their jobs. Their employer should rethink tactics.
