Rin's passion led her to open her own long-awaited personal training gym. Concerned that she would get lost in the crowd at a regular personal gym, she started posting videos of herself working out on social media. She then started to increase the number of members by making full use of her well-trained, sweaty body and her erotic techniques. Her method is... using an H-cup machine for a sweaty sex exercise with breast-tight stretching! She finishes off with a titty-fuck as a reward, and the members flock in! "When I work up a sweat and exercise, I get aroused right away... hehe."
