Is drinking pee healthy?

Well, I just wanted to confirm this here. I'm serious BTW. Is drinking pee healthy? Somebody told me drinking pee is healthier than drinking whatever she drank to produce it. Is this true? I need to know this because I usually engage in watersports play and I don't want to risk our health with this.

My sister is eight years older than I am, we love each other so much. This past weekend we was camping out in a RV. It was in the middle of the night, I was on the lower bed, and my sister was on the top bed. She came down to me, with both feet on each side of my head. She pulled down her pajamas, and panties and squated above my face, facing my head, saying I love you my little brother. She then took her hand, and got my mouth opened. She then positioned her pee hole over my mouth and sat down on my face. She rubbed my head with her hands saying everything is gonna be okay bubby. Suddenly I tasted salty water coming out of her, I drunk it down quick. After she got done, she asked if I was okay, and if I liked her pee? I said yeah. She said she would do it again. I have drunk her piss almost six times this past weekend and today, and I love it. She farted on my face today and I loved the smell. She told me that she would love to take a dump in my mouth and get me to eat it, and see if I like it. If I do like it, she said that I would become her full time toilet boy for my big sister. I love my sister so much, I want to take this risk for her because I respect what she wants
