Đi tiểu trong bồn tắm, có và không có quần lót

I had to piss in the tub for 24 hours, so here is 2 examples of that. The first one was normal so to speak, that is no panties or anything. The second one I piss into the tub wearing my panties (someone was buying them from me and wanted this). Which one do you think is more humiliating?
