This project is a full-scale documentary-style series that involves picking up amateur women on the street and filming real sex. This time, the subject is Karen, a 21-year-old girl DOC encountered while filming a "Masked Beauty" feature in Nakano. She was chatting with a friend after a group date. After explaining the concept of revealing her face by removing her mask and breaking her "masked beauty" image, both girls happily agreed. Her appearance was even more stunning than expected, truly living up to the title of masked beauty. Karen attends university to become a dental hygienist, which is why she usually wears a mask. Later, we invited her for an interview at a nearby izakaya. As a third-year student, Karen said her motivation for becoming a dental hygienist is "the good salary and the chance to meet doctors." Her honest, desire-driven attitude instantly attracted the crew. Perhaps because of the generous compensation offered, she readily agreed to the shoot. Karen shared her thoughts on male doctors: "Orthopedic doctors are flashy playboys, while internists are quiet and serious." Her descriptions sounded like firsthand experience. As we dug deeper, she revealed she once dated an internist. He had a bizarre fetish—spreading her pussy open just to look at it. Her friend standing nearby was visibly shocked. When a crew member went to the restroom, Karen followed. Inside the stall, she suddenly started giving a blowjob: "Talking about the past turned me on." While sucking, she masturbated herself. Her incredible blowjob technique brought the staff member to an intense climax, shooting cum straight into her mouth. She smiled brightly and swallowed every drop. Who would've thought she'd be such a wild girl! Afterward, she calmly returned to the interview as if nothing happened. When Karen mentioned she enjoys removing tartar, the crew became curious. "I have the tools, so it's totally fine!" she said, offering to give a real dental cleaning. After parting ways with her friend, we headed to a hotel. During the tartar removal, she pressed her breasts against him, teasing him. Honestly, the crew was hoping for this. Then, without warning, she said, "Kissing after tartar removal feels amazing," and kissed him deeply. In response, he sucked the large marshmallow breasts peeking from her clothes and experienced the "pussy gaping" she used to receive from her ex. Her pussy was visually and sensorially a perfect three-star experience! After enjoying her body through 69 and titty fuck, he penetrated her from behind. She moaned loudly, praising how deep and pleasurable it felt, then took over in cowgirl position, riding hard before finishing in missionary with rapid, deep thrusts. Finally, he erupted a massive load straight into her mouth.
