Supporting the clinic where patients addicted to fellatio gather is a nurse who is overly devoted and beautiful. No matter how rough the patient is, no matter how big the cock is, she envelops everything with her narrow, small, soft, and warm throat, making it melt away. No matter how many times she enters and exits the tight throat room, her erection is always cured. Even if she cries so much that she feels like she's going to vomit, she never refuses, determined to serve with her deep throat. While dripping with the semen that has been fully ejaculated, she blushes like an angel and says, "But this feels good." Her extreme masochistic saintly behavior is truly Masochistic Teresa.
