Damn... you should have pooped on her loofa while you had the chance.
Seriously, as long as you cleaned it out, the best thing would be to NOT tell anyone. The fuck did she want you to do?
"Hey honey, I shat all over the shower"
*what?*
"Yeah, I sharted in there, made a hell of a mess"
*you're kidding me, that's disgusting!*
"Get's worse, I got some on your loofa"
*OH MY GOD ARE YOU KIDDING ME, I'M GOING TO BE SICK!*
"It's ok, i cleaned it out realy good"
*... oh, well ok then. Now shhh, I'm watching What Not to Wear. luv yoo {hugs}*
