Yui is on a video call with a man she met on a matching app. Yui, who was masturbating according to the commands of a man she had never met, climaxed while being watched by the man and prostrated herself naked... One day, a man newly appointed to the department where Yui works. Yui, who inadvertently let out a voice at the familiar voice and familiar tie, was ordered to work overtime by the new department head and summoned to the department head's office. Yui, who faced the man in a closed room separated by only one door from the office where the employees are still remaining, had her body groped and climaxed with a full sense of immorality! When her clothes were disturbed and the hemp rope grazed her nipples every time, she became aroused, and she became even more intoxicated with the unrealistic "office bondage" and accepted cunnilingus in an unsightly manner. Yui, who sucked the raw dick deep into her throat with her bound, inconvenient body, begged for insertion herself and climaxed with plenty of masochistic pleasure. In the state of being restrained from behind, when she switched to cowgirl position, she swung her hips greedily and climaxed with a loud bang as she was thrust from below. Yui, who was creampied raw while shaking her huge breasts, conveyed her gratitude to the man in a dazed state... From then on, the office where the employees had left became an outlaw zone where the two secretly carried out SM play. In a situation where it is unknown when the employees will return, Yui, naked with a collar, is a "bitch dog" who engages in thrilling walk play. A vibrator is inserted into her pussy, and her cheap pussy cums like crazy as if broken. The two who met by fate, transcending the relationship of boss and subordinate, drown deeply in a master-slave relationship!!
