[Fan no Hitori] JK Taimabu Season 4 (semi-human translated)

Hokushin Academy's proud exorcism club sends its most powerful, big-breasted swordswomen to contain a monstrous outbreak far beyond their usual territory, only to find rival schools have hidden the annihilation of the last investigation team and left them walking blind into a nest of ravenous tentacle creatures. One after another, the voluptuous schoolgirls in uniform — from the startled Asami dragged from a bathroom drain to the thoroughbred samurai Shion whose spiritual barrier is painstakingly scraped away by writhing nubs — are overwhelmed, stretched and filled with massive, bumpy cocks and creampie until they are left defenseless, drooling and unable to use their spiritual arts. As thick tentacles coil around heaving breasts and thighs, forcing deep fisting penetration and pulsing violation that dissolves personality into helpless, humiliated ecstasy, the survivors must struggle to reclaim their bodies before the infestation melts them completely into docile, breeding flesh.
