[Semakute Kurai (Kyouan)] Ability measurement experiments of offspring born with superior and inferior genes and records (Touhou Project) [Full Color]

Reisen Udongein Inaba, the well-endowed lunar rabbit with soft fur and heavy breasts, becomes a living test subject in a breeding experiment that pairs her with a filthy, monstrous mate while a detached researcher records everything. Drugged to accelerate pregnancy, she cycles through birth after birth as clinical monitoring reports catalog her body's ruin — nipples stretched dark and bloated, senses drowning in musk and grime, her proud abilities eroding while her mind melts into ahegao haze. A final one-year comparison lays bare the cost of the experiment: over two hundred births, every power lost, and a broken bunny girl whispering for someone, anyone, to save her.
