Need help looking for a Doujin about female NTS aka Cuckqueaning. The premise was that the MC (girl) once watched a show where a woman seduces a man in a relationship, and seeing the despair of the cucked girl turns on the MC and she masturbates to it. Then she gets in a relationship with a guy and fantasises about him cheating on her, until one day she makes the request and films her BF having sex with another, voluptuous girl.
I swear I had saved this doujin but I cannot find it in my storage, using male:netorase tag on popular sites also doesn't get me anything.
Thanks in advance, and here's a pic for your trouble.
