Kosaka Mirina is a nursing student diligently studying to become a nurse. When she fails to show up for their meeting and stops responding to messages, he heads to the hospital—where he runs into her just after her training ends. In the quiet, empty atmosphere, he overhears her and a classmate talking about her skills. The classmate reveals that Mirina gives incredible blowjobs—so good that he once got blown to orgasm before they could even have sex. After gathering all the details, he prepares to leave, but Mirina suddenly guides him into an unoccupied hospital room. She confesses she's always wanted to do something naughty in the hospital. With stunning skill, she quickly brings him to full erection and swallows his cock deep into her saliva-filled mouth, sucking and squeezing tightly around it, delivering intense pleasure. Overwhelmed by sensation, he cums inside her mouth, and she happily swallows every drop with a smile. When he suggests moving on to sex, she agrees it's too risky here, so they immediately head to a hotel. At first hesitant during the rough play, Mirina gradually awakens to the pleasure of being dominated, embracing her deep masochistic side. In the end, her cute face is completely covered in thick, sticky cum.
