There's a Cat in My Bathtub

We had storms one night and my mother's electricity went out. So I had to bring her over here for the night. She went to use the bathroom and she comes back and says "There's a cat in your bathtub". My reply was, of course, "Just one?". My cats love to hang out in the tub. They lounge there, they insist on getting their water from the faucet dripping. I've tried to leave them water, even put a bowl in the bathtub but no, they want it fresh from the tap. Whenever you sit on the toilet, the female tiger suddenly appears and walks along the edge of the tub wanting to be petted. She does not like to be held., Won't let you pick her up. So I always have had a terrible time brushing her. Finally, it dawns on me the other day, just brush her in the tub! Ok, So I am slow...So there I was, brushing the cat, bent over the tub, my ass in the air. She absolutely loved it, rolled around in there, even let me brush her stomach which she really doesn't like to be touched. All went well until in her ecstasy at being brushed she gave one of those low growl-purr-meow sounds, something close to a hot sweaty sex sound (as well as I can remember). This alerted Dempsey, the dog, that someone was getting attention other than he and he came to check it out, which of course upset the whole bonding moment that Lily and I had going on. It's kind of strange, that I have to sneak around with my other pets, so that Dempsey doesn't find out...almost like an adulterer. But then I guess it's kind of strange that I have a cat (or 2) in my bathtub.
