This is a half machine translated half me translating.
This one was really hard to clean up...and I'll probably never attempt to do this ever again. And yes, the plot is as nonsensical as usual, just go with the flow people.
Do tell me if there are any errors to fix!

Aleliuha! finally a Houseki no kuni portraying the pseudo petanko -Girls- i wished to see since long ago!

All the Jewels are as beautiful as their gems here... but the best part: Borz in bunny suit... i have been waiting long to see that in a doujinshi.

The sex action goes along with the slender bodies and the femenine forms (specially in the hips).

Gorgeous! Thanks a lot NSFWSB.

Turns out the “I’m immortal” line was a lie, our hero died of mercury poisoning about a week after fucking Cinnabar

Would just like to mention in case people don't know, gems have no gender, so it's okay to love them. Like a good boi once said about FGO's Enkidu: "It ain't gay, if it's clay"

@Triforce777
adamant the hero? I think not! :P (pretty sure this doujin has adamant sensei as our faceless dick though)
that said I think it was covered in either the manga that cinnabar wasn't able to (easily) corrode adamant... though it has been a long while since I've read the early parts of the series. >_>

also food for thought, if adamant is unable to touch cinnabar how did he sculpt her? I don't remember seeing any glass work or plastics so I doubt he used any sort of special gloves or full body suit. ;)
