Should I undergo long nipple torture sessions?

With the daily sessions my nipples are kept rather sore permanently. Even with these already being very painful he is considering adding longer sessions that last a day or longer. I do not want to undergo these but it will be up to the vote.

Note from MeisterAndrew: Carla recently had a session lasting two days where her nipples were subjected to constant torture for the entire day. With her nipples kept permanently sore this must be an excruciatingly painful punishment for her. Should these occur on a more regular basis? Also if yes how often should they occur?

Edit: There seems to be a concern over Carla's comfort and enjoyment of this. This shouldn't be a consideration and only whether or not she should have to endure such pain. Strict and harsh dominance has always done her good and resulted in her behaving better and improved her demeanour.
