Ririka is on a business trip with her boss, whom she dislikes, and is caught in a sudden downpour, so she ends up staying overnight. She goes out drinking with her boss, but ends up getting muddied. When she takes off her wet jacket, she is shown to have plump breasts and moody purple underwear that are hard to imagine given her cute, petite figure. "That's unfair!" The boss, seeing her body like that, lets his desires take over. Her body is unsatisfied, but she is reluctant, and her body is convulsing and climaxing. Her small mouth is full to the brim, and her blowjob is dripping with saliva. Her boyfriend calls with concern, but she is more ferocious in her standing doggy style pistons. A high-speed cowgirl fuck with rain, sweat, and bodily fluids flying everywhere. A generous creampie in her beautiful cherry-colored vagina. Her frustrated body gradually becomes more aggressive... "It was the boss who turned it on, so you have to take responsibility!"
