Lol, I had an ex girlfriend who accidentally took a mouthful of my piss from a bottle she'd set her drink next to one time. I'm pretty lazy and had bottles of old urine placed all over my table surrounding my laptop because I disliked getting up to go to the bathroom. We were watching a movie together and the bottle of piss she'd set her drink next to was from the same brand of tea as her's which she'd brought over. She picked up the wrong bottle and once she took a swig of it a look of dread immediately came over her face. She started flapping her hands as she ran to the bathroom to spit it out. A few months later she brought it up saying, "Remember, how I drank your pee ha ha?" with a look of genuine pride.
The difference between me and someone like you is girls never get the ick from me regardless of what I do.
