Does anyone know why Hentai studios seemingly stopped doing stuff like this? Back in the day I felt like plenty of freaky tentacle porn was made in Japan but now-a-days it's all Blender stuff from around the world with Hentai being mostly vanilla. Really happy to see this level of production for a tentacle breeding Hentai.
In the 1980/1990s, tentacles were invented to get around the censorship laws which, when taken literally, said you couldn't show a penis.
So studios would make tentacle anime as there was a market for uncensored penetration since it was the only way to see animated things going into girls. See all the "Of Darkness" h-animes which included tentacle scenes and normal scenes to appeal to both markets.
Then in the 2000s, the censors started censoring tentacles as well. Sometimes heavily--meaning that sometimes the entire screen was pixelated with all the random tentacles in the air. You can see this in Pandra when the whole screen is just a big blurry mess sometimes.
At the same time, the 2000s international market for hentai expanded, so overseas companies started licensing more vanilla h-anime for Western releases.
This meant that Japanese companies could legally sell their uncensored penises overseas. So they had valid legal reasons to keep an uncensored version as well as a censored version. So now you can draw penises without having to censor them or find loopholes like tentacles.
So by the 2010s, it became VERY easy to find uncensored generic male-female penetrative sex across the internet.
This meant animating tentacles became less profitable and very niche, as it would mostly appeal to people who developed that fetish over the past 20-30 years.
The rest of the world would've already been seeing uncensored male-female hentai since the 2010s and would've developed the fetish for generic hentai with no tentacles.
So by 2023, it's easier, legal, and more profitable to just animate generic male-female penetrative sex.
