I was instantly hooked by the concept that lured Mariri Natsu out under the guise of a hot spring location shoot, leading to an exposed filming session. The fake interview in the moving car quickly transitions into a walk along a side path for some humiliating play. In a sparsely populated area, she's fitted with a vibrator and made to walk while being brought to orgasm, creating a mix of tension and excitement that's a key highlight. Later, moving to a forest path, she's forced into continuous climaxes using vibrators and electric massagers on her private parts. With her erect nipples exposed, she endures deep throat, outdoor urination in underwear, and raw sex by a building—the series of perverted acts vividly depicts how initial shame transforms into pleasure. The climax in the mixed-gender open-air bath is particularly stunning, where she engages in wild, genuine sex, reveling in the thrill of being seen by other patrons, culminating in a joyful exposed climax while being showered with semen. Mariri Natsu's acting shines, offering a full taste of the unique realism of outdoor settings, making this a must-watch for fans.
