[Hirno] Shinshoku Inkan Erosion zone (Seigi no Heroine Kangoku File Vol 3) [Colorized]

An investigation into a mysterious erosion zone leads a heroic figure into a trap where the line between captive and mother blurs. Surrounded by a fleshy, pulsating environment, she discovers that the captives here are being used as a breeding nursery, serviced by relentless tentacle monsters. As the strange biological forces begin to expand her body and overwhelm her senses, she finds herself caught in a cycle of constant stimulation and insemination that turns a mission of rescue into a journey of instinctive surrender.
