[Ishida Kazuma] Tentacle Hole Chapter 13

A hero willingly surrenders to his monstrous side, transforming into an armored titan to clash with a ravenous flesh-beast in a shattered wasteland where the only law is eat or be eaten. As boulders fly and a screaming creature is pounded into rubble, a terrified girl finds herself swallowed by grasping tentacles while a grotesque skull-faced crawler grovels for a chance to be taken to the surface as a research specimen. Enter a statuesque, thick-thighed beauty with her bare chest barely contained by tattered cloth, who shamelessly begs to join the survey squadron, promising that the tentacle she carries and her own voluptuous body will be an invaluable boon to tentacle research.
