[Gekka Kaguya] Monster Training (2D Comic Magazine Shikyuu Knock de Portio Zecchou! Vol. 2) [Pangean]

Three months after the kingdom's greatest magical swordswoman vanishes, her devoted little sister Marron rides into monster territory to find her—only to discover her big sister collared, blissfully broken, and worshipping the huge cocks of the orc pack that took her. Rescue curdles into corruption as the beaming big sister joins in, pinning Marron down to savor 'the feeling of being raped by your beloved big sister' while stomach-deforming orc thrusts and x-ray views of cervix-deep penetration grind down the girl's murderous defiance. With her death threats dissolving into ahegao under the pack's relentless breeding and her sister cooing praise over every shudder, Marron's own monster training has only just begun.
