22-year-old "Karen-san", a receptionist at a company in Minato-ku, has her first shoot. As she is in her first year as a working adult, she answers the interview with a little embarrassment and a hint of fear in her eyes as she is gazed at by a man. She has a bright and cheerful personality with a good smile, but tends to keep men at bay, and currently doesn't have a boyfriend. In the presence of a long-absent sensual atmosphere, she becomes a little more demure. As her tense body is slowly relaxed, her beautiful nipples, like azuki beans, come into view. As she receives gentle caresses, she gradually becomes excited, and her breathing becomes rough. When her panties are pulled down and her sensitive areas are stimulated, she reaches climax with a twitching waist. She stains the sofa with a large amount of squirt, and the sight of her wiping her own squirt off the camera while saying "I'm sorry..." is very endearing and impressive. The roles reverse, and Karen-san starts to show interest in the male genitalia after a long time. She sniffs the smell of the penis and slowly licks it. With a seductive smile on her face, she devotes herself to the man, but when her vagina is stimulated, she squirts again. Then, her soaked panties are removed, and the erect penis is inserted deep into her vagina. The area around her crotch overflows with lustful fluids, and with each thrust, obscene sounds echo throughout the room. Unable to bear the intense pleasure, she screams "I want to cum!!!" The man tries to stop her, saying "No, you can't," but she is teased and can't help but feel the pleasure, her slender body jumping wildly. The receptionist is made to cum while showing her obscene pose by the window of a high-rise building. In the end, while her face remains beautiful, the hidden passion deep within her is revealed.
