Will my dog be OK?

Last night my SO and I were mixing it up a bit. I was on top of her, with my anus pointed downward toward the small of her back. I put a Snoopy dime eraser in my shithole and gave her a backrub with my ass. About midway through, however, I nearly sprayed her back with with this brownish, viscous fluid that smelled a lot like shit but did not feel at all like that while coming out (I managed to jump off her and shoot it on the dog--don't ask!). Has anyone ever had this happen before, and will my dog be OK?
