New Daddy, crazy challenges

I met my daddy a few weeks ago (I was really really shy but he's trying to get me out of it) and he gives me challenges to do each week. One of his rules are that if he orders me to do something, I do it or we break up. This really keeps me motivated since I care about him a lot. One of the things he told me we were going to try at some point was BINDER CLIPS on my nipples. Guys I am terrified. Idk if I can do that. Any tips on how to get over the pain, or like stretch out the clips so they aren't so harsh or something? Thanks

********(no comments about our relationship please, I just want to know tips about the binder clips)******

UPDATE: I did it guys!!! It wasn't as bad as I thought, but it still hurt. His nipples are apparently way more sensitive bc he yelled and cursed when he did it and it just took my breath and i bit my hand to keep from yelling. lol I win. He also is pushing back next week's punishment for me being so good ^.^ we get to watch little movies and talk all week now ☺️☺️☺️
