Beyond the boundaries of seniority as actresses, "Yuko Shiraki" and "Mizuki Yayoi" are reliable as "beautiful sisters" even though it is their first time acting together! In order to let them relax and open up their bodies and Kokoro in the great outdoors away from the studio, the shooting started in a moving car! The two of them giggled and fed each other jelly snacks. When they left the service area and went to different cars, they started playing naughty games with remote control vibrators, writhing around while imagining each other...! As expected, when Shiraki arrived at the scene, she had climaxed with the vibrator in her panties, and Yayoi, holding the remote control, looked proud of herself, saying "I got you!" Yayoi sniffed Shiraki's sweaty panties, soaked in her pussy juice, and her sexual desire was heightened by the lewd smell, and she licked Shiraki's toes to her anus to show her affection. They switched roles, and Yayoi was in agony from Shiraki's deadly feather touch! Yayoi, who made Shiraki cum so many times, can't hide her excitement and tension when her senior Shiraki makes her cum in return. With her crotch-split panties wide open, Yayoi's shaved pussy is exposed, and her sensitive clitoris is sucked and licked thoroughly, causing her to scream and climax! The cheeky and cute junior Yayoi quickly loses her strength and completely submits, entrusting her defenseless body to her senior Shiraki. Yayoi, who was on edge, thinking "I have to make my senior cum!", changes to a relieved expression thanks to the orgasm-making exchange with Shiraki, who has relaxed in a good way. Following the back of her beloved senior who is 'entrusting her with his body', she exchanges affection with him, entangled in deep kisses as if they melt into each other until the night is well underway!
