BBAN-023 — Married Nurse Confinement Anal Lesbian Ayumi Takanashi Kotomi Asakura

One day, Ayumi hears a rumor from her colleague Kotomi that "nurses are being used as test subjects for new drugs in an abandoned hospital ward nearby." That night, the two of them break into the ward to see if the rumor is true. However, there they discover the hospital's hidden side - the presence of a female doctor named Kuroki who has been holding nurses captive and using them as human experimentation tools in order to create human "regenerative cells." The two of them end up being held captive by Kuroki as well, and end up having a new drug applied directly to their rectums (anus).
