Synopsis
——When they regained consciousness, they found themselves in another world.
Saya and Ai Kasuga, renowned beautiful sisters, worked at the same bookstore. Recently, Ai had been troubled by a suspicious man who kept following her.
One day on their way home, while fleeing from the stalker who boarded the same bus, an argument ensues as the bus enters a tunnel. When they emerge on the other side, they discover a parallel world where the roles of humans and livestock have been reversed.
Dogs, monkeys, and cattle—creatures that were once pets on Earth—now manage humans as “human livestock” (jinchiku), controlling them as pets and cattle using human language.
The two sisters find themselves in disaster. They witness naked women being walked like animals and are discovered by a bear security guard. After escaping too late and being stripped naked on the spot, they are taken to a facility for human livestock education, where they are trained with restraint devices and violated by monkeys and bears.
The sisters are then auctioned off as livestock and begin their new lives serving their masters’ commands—forced to have sex until impregnation with the stalker they despise, made to pull human-powered carriages, milked by machines while being violated by cattle, and serving as milk suppliers at cafes.
In public training, they perform forced fellatio on pigs and are walked through the streets as dog livestock.
The adult content features 80% beast scenarios and 20% human scenarios, primarily focusing on non-human creature interactions.
Welcome to Livestock Planet—a world where animals dominate humanity.
Editorial Review
This is an extreme-end exploitation title that commits fully to its premise: a role-reversal fantasy where human women are systematically dehumanized in a parallel world structured around their subjugation. It occupies the hardest edge of bestiality content within the adult doujin space, pairing xenophilic abuse with slavery infrastructure and reproductive coercion themes.
What distinguishes this work within its niche is the world-building investment. Rather than treating the bestiality and bondage as isolated scenarios, the synopsis establishes an entire civilization with institutional frameworks—the “human livestock education facility,” security hierarchies, and systematic degradation protocols. This systematic approach to degradation is uncommon; most titles in this territory prioritize immediate graphic content over narrative scaffolding. The parallel-world framing device also provides narrative justification for the role inversion, lending a speculative-fiction veneer to material that would otherwise feel purely punitive.
The character choice of recognizable sisters from ordinary Earth circumstances (bookstore workers) contrasts sharply with their rapid descent into captivity and abuse, which intensifies the humiliation arc the tags emphasize. The combination of large breasts, lactation, and impregnation themes suggests the work is investing heavily in fertility-fetish elements alongside the core degradation narrative—a layering that appeals to a specific subset of consumers interested in reproductive violation themes.
This work is exclusively for consumers with explicit tolerance for bestiality content paired with slavery, bondage, and forced impregnation. There is no tonal lightness or comedic framing here—it’s designed as serious-minded extreme exploitation.
For readers with crystallized preferences in this territory who seek institutional slavery frameworks and xenophilic content with world-building coherence rather than isolated scenes, this delivers exactly what its tags promise without apparent compromise.
