She's a diligent and clean-cut dental hygienist. She receives a strange request from a man who's a virgin for 20 years and hasn't had a woman in ages: "I want you to take care of him." At first, she's confused, but seeing the man's desperate appearance and his tremblingly hard cock, a heart of compassion (?) begins to throb. She only intended to help, but she's so moved by the man's passion that she finds herself opening her legs herself. Under the guise of helping someone, he gives her a deep creampie injection. Her gentle sighs and the man's roar, driven mad by pleasure he's not experienced in a long time, echo in the closed room, not the examination room.
