I was doing work about 10 years ago at a CEO's home office, he wasn't home, but his wife was, and they had a great dane that licked me in the face when i came in, mind you I am 6ft 5... After I was done I came down the hall and apparently I dropped something, she said something like, you dropped your papers, and when i turned around, she knelt down to grab it about 15 feet away, and the dog was on her instantly, paws around her sides, mind you she was fully clothed, but her reaction told me everything i needed to know. She wasn't stunned, or in shock, she giggled under her breath, slid out from under him, and brought the papers to me, and her face was red as a rocket, and I could tell she was sizing me up to see if I was perturbed by it. As I was headed to the front door to leave my suspicious were confirmed pretty much, she was back towards the kitchen, 20 ish feet away, he stuck his nose up between her legs from behind her, and she swatted at him and I swear i heard her say, "not now, later!" They really should not have marble floors, it makes it so easy to eavesdrop on what is being said, and what is happening, XD!
I half considered for a second or two dropping a hint to her that I was "likeminded" but I decided, that might create un-due complications in my own life if they knew that, so I just played dumb and like I didn't know or didn't care, and left.
