One day, I woke up to find a nurse in front of me... "Good morning, you had a hard time yesterday." "I'm Yui, and I'll be taking care of you from today. If you need anything, please let me know." First, let's wipe your whole body. "Let's clean every inch of your body." "Please take off your pants." I was confused and tried to refuse, but she told me that I'm a swallowing nurse who drinks the sperm of patients to check their health condition.
