Some ones you have probably heard of that are my personal recs:
Our Future - not a bad story but the plot doesn't purely focus on bdsm
Blood Bank - youve probably heard of this one but god is it amazing
Ang Ang - true bdsm type story
Make a Pet Out of a Cactus - super romantic and short manga! one of my favs honestly
Aporia - not really masochism but one of the best bdsm centered stories

Here is a link to a list for bdsm recs:
