Elite investigator Kanna infiltrates a pharmaceutical hideout rumored to trade illegal aphrodisiacs, but she is ambushed and captured after uncovering its crimes. Used as a test subject, her huge breasts and pussy are slowly tortured under a concentrated drug until she convulses in unwanted orgasms before men she despises. Surrounded by drug-fueled erections, she is forced to suck and give titjobs before being gang-penetrated. Her mouth and body are drenched in thick cum, and the proud investigator is humiliated, abused, and conquered by overwhelming pleasure.
