allow me to answer your question with another question. why would a partner think it's hot when their partner acts like a dog? it's all a costume, the thing people find hot is the power dynamic involved. the reason people would be into that is bc it's their partner, a consenting Adult, making a conscious decision to act a certain way and give their dom this control over them. even in my fic, Ys is an adult, views himself as an adult, and even if sh treats him a certain way within the fic he is at the end of the day An Adult. bottom line it's a kink and lifestyle between adults and if you don't like it or get it that's fine! you don't have to read or participate
