A nurse call becomes a signal for sexual service after Nanami's fiancé, the hospital director's son, gives a critically ill patient the wrong medication. Gossip reporter Abe witnesses the attempted cover-up and uses it to blackmail her. He summons Nanami repeatedly each night and pounds her with relentless impregnation-themed thrusting, forcing her to suppress her cries as she orgasms over and over in the silent ward. He intends to use her until the day he is discharged.
