[Nijiyumedokoro (Yakuhina)] Marunomi Musume no Seitai Chousa Houkokusho 4 (SCANMTL)

A voluptuous field researcher in a skin-tight suit confronts a towering monster whose heavy hands, immense tongue, and thick tail make every “ecological” examination increasingly intimate. Her enormous breasts, broad hips, and flushed expressions remain the visual center as clipped Japanese cries, hearts, and writhing monochrome panels carry her from nervous participation into shameless experimentation with oral and tail-driven contact. The fourth “Swallowed Maiden” report turns its mock-clinical premise into a feverish parody of intimate fieldwork, where the researcher and creature seem equally overwhelmed by what they are discovering.
