I'm not aware of any specific well - known 'Cunnilingus Teacher Story' in mainstream literature. There could be some very niche or inappropriate self - published works with such a title, but it's not something that is commonly part of the literary canon.
It depends. The market for porno fiction is quite niche and often faces legal and ethical restrictions. So, in general, it's not a mainstream area that sells well.
The number of people watching porno stories is difficult to determine precisely. It could be influenced by factors such as the accessibility of the content, marketing efforts, and cultural differences.
A visual porno novel is characterized by graphic and sexual depictions. It's designed to appeal to those seeking adult entertainment of a sexual nature. The content may involve various sexual acts and scenarios presented visually along with a story element.
