A collection of short stories and random ideas that the artist decided to (quite literally) flesh out a little bit. Nothing really groundbreaking, but it's still great content.
A bit quick on the upload again, hasn't even been a week. I haven't even started translating this piece yet... but alas. I'll update this comment when I'm done with the translation.
Anyway, great to see another Piyokoro Ryouiki after so long. Though it isn't the usual format of a bunch of compiled one-off/rejected drawings, these 4 short stories do stem from such drawings. Piyo also talked in the afterword that he regained motivation where he previously felt lost, which could mean that he now is working on continuing Tentamashii Tama and Kai • Takkyo-ku Chousa Nisshi. But that's just speculation on my part, only time will tell what he'll release next.
EDIT: Here is my translation, at last. Sorry it took a bit longer.
We've got 4 stories in this one: some sights to see in a futanari society not unlike Takkyo-ku Chousa Nisshi; a perverted scientist testing his breast-expanding 'pai-lot suit' out on his assistant; humans gifted with futanari 'weapons' to combat a nymphomaniac tribe of monsters; and a guy reincarnated as a slime invading and expanding an adventurer's breasts as revenge for slaying him.
