Your couch is is gonna be ruined by ME and all the other Men we'll piss in the fridge on the walls make the wallpaper all wavy piss on the floor and sink onto TV inside the washing machine and dryer into potted plants...use your bedroom....piss in the closet onto the clothes Etc 

Whenever I use a public urinal, I always go in and seek out a guy in his 50s+ and use the urinal next to him. I stand far enough away to give him a good view if he wants to peek and also to prevent splash back from the urinal itself. I take out my cock and balls and begin to piss a good steam and try to glance if the person next to me is trying to get a peek. If he is, I make sure I shake and stroke the drippings a bit longer than usual.

Omfg wow. What a hot experience! I can picture how the sound of that lady peeing on the towel, combined with feeling the warmth of her pee along with the smell of her pee would have led to you cuming so fast and hard. A once in a lifetime experience for sure. I would have done the same if I was in your position.
