"Punctuation!" by Hanazawa Kana

Summary is a bit misleading. Rather than an physiology seminar, this seminar is more about educating each other on sexual deviancy.

Now normally, a "pervert" in anime just means they like sex a lot or think about it a lot, or want it really badly. Not so in this one, these people are real perverts. They eat insects, trick one another into consuming semen, pee in public, break into one another's houses and do weird stuff to them while they're asleep. If this was the real world, these people would probably be in prison.

Watching Hen Zemi is a bit like catching your friend trying to stick a carrot in their ass. It's awkward and repulsive but you just can't turn away. This series literally opens up the pandora box of human sexuality. NTR, masochism, humiliation, voyeurism, watersports... jesus fucking christ. This series is downright creepy.

The story and premise are simple. A couple of university students join forces together on their quest for ultimate perversion as they drink piss and shove stuff into each other. That's the whole series in a sentence. Yeah, they do also eloquently talk about the philosophy of their perverted quirts but in the ...
