Breastfeeding around dad

My dad is coming to town tonight and staying for 10 days to meet his first grandchild and help out. No one in my family has ever breastfed so it’s all new to him hearing me talk about it. My mil is leaving today and I’ve pretty much been naked around her this week since I had a c section and been recovering. I just started wearing clothing about 2-3 days ago. Anyways should I just pop it out and feed or should I cover my breast as I feed? Anyone deal with this before.

Update: My dad actually asked my husband to grab me a blanket because it made him uncomfortable when he would look up to talk to me
