"Addicted to Bound and 'Dog Training' Office Lady Yui Hatano CEMD-817"

Yui is video chatting with a man she met on a dating app. Following the orders of this man she's never met, Yui masturbates, reaching orgasm while he watches, then kneels naked in worship… One day, a new man joins Yui's department. Yui can't help but make a sound because he has a familiar voice and a familiar tie. Yui is ordered to work overtime by the new department head and is called to the head's office. In the secret room, separated from the other employees by a door, facing the man, Yui's body is touched, reaching orgasm with a sense of transgression! Her clothes are disheveled, and the rope brushing against her nipples ignites her desire; she becomes even more intoxicated by the unrealistic 'office bondage,' accepting licking of her genitals in an unbearable posture. With her tightly bound, unfree body, Yui, sucking a raw penis deep into her throat, begs for penetration, experiencing repeated orgasms with a masochistic urge. With her hands restrained behind her, she is placed in a riding position, greedily swaying her hips, being thrust into from below, reaching orgasm with a creaking sound. While swaying her large breasts, Yui, being penetrated without a condom, expresses her gratitude to the man in a dazed state… From then on, the office where the company members left becomes a lawless zone for secret two-person SM games. Not knowing when the company members will return, Yui, naked and wearing a collar, engages in a stimulating "bitch walk" play. A vibrating egg is inserted into her vagina, and her slutty vagina climaxes wildly as if it's broken. The two, who met because of a twist of fate, transcend the relationship between superior and subordinate, deeply indulging in a master-servant relationship of mutual dependence!!
