Nanami's careless idea that sugar dating is just a simple game was a mistake... Her sugar daddy introduces her to a high-paying part-time job, but it turns out she's locked up in a place where no one will come to her aid even if she screams and cries, and she's brainwashed and subjected to intense training. She's tied up behind bars, fitted with a pet collar and leash, and her pussy is toy-trained until she climaxes. No matter how cruelly they treat her, she's taught to say "thank you." While restrained, she is subjected to hard deep throating by men, who cum deep in her throat repeatedly, and finally swallows it all. Just when she thinks she's freed from her restraints, the men lick her from her toes to her face, finger deep throating her, and repeatedly inserting their dicks into her mouth and pussy in a massive 5P orgy, drinking up all the semen!
