I don't have any interest in BDSM so I can't tell you how it is from the information department, but I thought it was a pretty decent introduction. Concerning power dynamics and fetishes it was interesting.
But this is smut for smut's sake. 7/10 interesting if nothing else.
In the first chapter their fingers and toes are so fucking long I found that strange. Idk if that itself is a fetish, like something tied to feet but I did find that off puting
