Where can I find

Okay so don't mind the video guys, Ive been searching for another stuff but I cant get it so I need your help please. It's an interactive story. In my souvenirs, it was on an application like taboo, or choices... it's erotic and sexy. It's about a woman who wants to know more about bdsm so she finds a dom who will train her but he will ask her, at the end of the training, to be a submissive to another guy. And therefore we have a story between them 3. The other master treats her like shit and is close to her master who trains her. It's like the book "submissive beauty" if you read the summary but as an interactive free story. Please help, I need to find it again. THANKS for your help
