It's romantic, sometimes funny and based on a visual novel. Kazumi Kouta wakes up in Aki's room and takes a moment to remember why he's here. Aki reacts similarly, but with more screaming.

KOUTA'S MOTHER: "The bathroom had a problem. Since that needed repairs anyway, I decided to renovate the whole house. I know it's sudden, but I'm abroad with your dad right now. You'll be staying at Aki-chan's place, starting tomorrow! I already talked to them about it. Bye!"

AKI'S MOTHER: tells Kouta to have a bath at a time when he'll get an eyeful of her daughter. "Goodness me! I had nooooo idea Aki was in there!" Later, she playfully tells them not to give her a grandchild before they've graduated.

Aki and Kouta are next door neighbours and childhood friends. It's a charming episode. There's lots of sex, but also plenty of platonic scenes. Their classmates lumber our heroes with the job of taking cosplay photos for the school culture festival, for instance. It ends with a love declaration and Aki dressed as a bride.

For a while I thought this was Aibeya ep.2, but with a different couple. Both stories are warm, likeable and romantic, but Aikagi was better.

Nozomu's thinking of moving out of home, but his classmate Shiori's already been living alone for three years. Would he like to move in with her, just to see how it works?

A perfectly normal schoolgirl, Erika, gets a course of treatment from the school nurse. This involves lasers, a fellatio machine that makes you urinate and a chair with nipple suction pumps. A gun gets inserted into a private place and fired. She also uses assorted weird and possibly alien dildos. Whatever her problem was, this seems unlikely to cure it.

The nurse has group sex and acquires more victims, one of whom is way too young.

The other, longer episode has even less plot, but a greater range of surprising technology.

A bride is having sex. "It's as if my childhood dream has come true."

She wants a baby. The title says that's why they're having so much sex, but it's hard to get pregnant from fellatio and boob jobs. They do ultimately succeed, though. It's nice.

The CGI's not bad, but the faces look like dolls when they move.

Our hero lives with his sisters and his brother-in-law. The sisters are having sex with each other, so they're soon including their brother too. They both get pregnant. The younger one thinks she'll marry her brother and talks of having his second child once the first one's born.

That's Venom from Spider-Man. A woman in beautifully rendered CGI is shagging a Marvel comics character on an alien planet. (That alien spaceship looks pretty amazing, too.)

The only dialogue is moans and panting.

Bet you didn't know that Venom's semen is colourless. Let's tell Disney that that's canon now.

"There's a secret sex industry in this apartment complex. While their husbands are away, these wives can be used as outlets for lust. That sense of immorality turns on men, who then become customers."

Room #305: Takei Mitsuru (24 years old). She's blindfolded and tied up. She tells her customer to hurry up. We see a flashback to her husband saying he's too tired to have sex. She enjoys lots of rough, then becomes normal and dutiful when her husband comes home.

Room #512: Asahina Aya (20 years old). She's trying not to wake up the baby, but not very hard. Her customer offers her an extra 10,000 yen to do it without a condom.

Based on a manga that's also had at least one live-action adaptation. (Yes, porn.)

A boy called Ken visits a girl called Komachi. At first she's timid, but soon she's having sex with him.

Its episodes exist in TV versions (3 minutes long, safe for broadcast) and streaming versions (6 minutes, unsafe). I watched the latter.

Souta Tsukishima's dad runs a sentou (public bathhouse) and also works as its back washer. I've never heard of that, although maybe I'm just ignorant. It used to happen, mind you. That's where "soapland" prostitutes come from, while there were male washing assistants called sansuke until 1870.

Anyway, Souta's best enemies with Aoi Yuzuki, a girl on the school volleyball team. Dad gets a bad back and Souta has to step in, whereupon of course the volleyball team shows up. Amazingly, Aoi doesn't recognise him even though he's "washing" her breasts and groin in front of everyone.

The hentai content is dodgy, weird and implausible. (Super-tame, though.) Are those girls all idiots? However the characterisation and situations are fun, while there's even a twist. Souta's likeable, despite his plot role. I'll keep watching.

A girl with stringy pink hair is playing a 1980s arcade game when the joystick turns into a penis. She makes use of it and gets pulled into the machine to have sex with the penis's female owner.

There are two versions of this video, depending on whether you want one or two shemales. The pink-haired girl sometimes has a penis too.

The music's reminiscent of 1980s video games and there's no dancing.

Lots and lots of different girls have sex, in succession. No plot or characterisation. It's just sex scenes.

I recognised some of them, though. There's YoRHa No.2 Type B from Nier: Automata. There are also characters from Naruto and, I think, One Piece.
