New nurse Miina Wakatuki's first day on the job at a shared house for elderly male patients quickly turns into a sexual ordeal. Despite her tall, slender frame and large breasts, she's overpowered by a short but dominant old man who forcefully demands breakfast—sucking on her tits and eating her pussy under false pretenses. Her tight pussy is inspected and then penetrated bareback, her natural tightness only fueling their lust. Soon, creampie after creampie is forcibly shot deep inside her as the residents, claiming it's for improved vitality, take turns fucking her raw.
