We AREN'T talking about watching. We're talking about the expectation of access to the bodily orifices of another human, as a "payment" or "obligation" in return for using the owner's dog. How flaming "beloved" can the critter be if the owner was willing to pimp him/her out to a stranger? We're talking about keeping ones word in a basic contract, albeit a verbal contract. Handsome has nothing to do with it, either. Fact is, there is a breed of human, generally male, who believe that if a chick would fuck a DOG, she'd fuck any HUMAN male who asked, a ridiculous and stupid belief. An equal fact is....many of THOSE show up in forums like this one. B/F was full of them. A lot of those nits call themselves Zoo, when what they REALLY are are voyeurs. I fought with a particular fatheaded admin at B/F over that, and damned near got pitched out. Happens HE was a watcher, too, not a doer. Some of those boys would try to talk a person into ANY thing, no matter how dangerous or risky, just so they could watch. Pigs and predators....in the WORST possible connotation of those words.
Yes, a person who hasn't got a critter needs to know what is reasonable, expectation-wise, from an owner, but the owner needs to live up to the agreement. They often do not. IF THEY DO NOT, and push themselves on another person, it is just another form of rape.
