There is nothing quite like adding cupping to melon torture session. Watching my slave squirm in pain from pressue of cupping really brings smile to my face. & happier I get more intense tit torture session becomes. Suction cups really put serious OW! in your slave's day. It is not as painful sensation as alligator mpegs or hot wax, however if you always use extremme torture, after while it stops having same effect. You have to vary not only type of torture you use however also intensity. It keeps your submissive guessing. She never knows what to expect next.
