TIFU Embarrassing drunk story

So this happened a while ago, however I decided to share this story with the internet. One summer night along time ago, my bro his GF and I decided we were all getting hammered. To be specific we were drinking tequila. We drank most of the night and the last thing that I remember is passing out on the couch. At some point in the night i started sleep walking. In my drunken, somehow physically capable of walking slumber, my body decided on a plan that my mind refused to be present for, so my mind entered the witness protection program (blackout drunk). I went in to my brothers room, where he and his innocent gf at the time lay so peaceful and still. My bro apparently had been awake trying to go to bed, so i find out later the next day when i hear about my drunken escapades. I , in my blacked out genius thinking, walk over to the edge of my brothers bed. he lay there feeling a still in the air of the calm before the storm. He turns over and looks up to see me standing there, so full of shock he is speechless for he knows what comes next. The storm arrives and him and his gf get a golden shower as i decide to make it rain on them. He yells fuck and throws the blanket over them but it is too late. His girlfriend wakes up as her curly hair is drenched from the thunderstorm. The shocked and angry Puerto Rican girl begins screaming at my brother in spanish, a language he knows nothing of. So while my poor brother is being screamed at in spanish, while he is soaked in tequila piss, his own bed soaked down to the mattress, i am still pissing. His gf, who is also one of my besties, blamed him and stormed out of the apartment for the night. He looks at me slowly fumbling around, making my way to the couch to pass out as if nothing had happened. I found out the next day when my mind had returned from the witness protection program, all that unfolded the night before

TL:DR. tequila got me blacked out, sleepwalk to my brothers room, he and his girl gets golden shower, she gets mad at him
