[R-gen] Maidenly Bloom Fallen Chapter 2 (Seisoku Kaihatsu Torawareta Erufu no Choukyou Jikken) [Kuraudo]

When the human kingdom unleashes its mechanical 'monsters' upon the elven realm, a dark-skinned elf warrior named Mell stays behind so her people can flee — and pays for that courage as a captive test subject. Strapped down amid coiling mechanical arms, her big breasts endure prototype training devices: stabbing probes, suction milking machines with a vibration feature, and electrical signals cranked to the maximum while an unseen experimenter records every reaction. Taunted by name and pushed past her limits, Mell's defiant glare melts into rolled-back eyes and broken cries as the training experiment works to break her completely.
