Oh yes! Call me gross, but i love the smell of canine breath, the warm drool and soft, yet strong tongue.
I've always fantasized about it, but i only got to do it once, with my friends old female mutt. She doesn't get much attention these days since my friend's family got a younger and more active dog.
One time, when i was inside with her, and everyone was outside, i knelt down to let her give some kisses, like normal, and was surprised when she really insisted on french kissing, and i didn't have the heart to tell her no.
For the briefest moment, perhaps, 10 seconds, i let her lick all inside my mouth and i licked her back, tasting her wonderfully salty nose and getting a decent amount of drool in and around my mouth. I was surprised how much i liked the taste and scent of her, i always thought i would be grossed out about it, and that kept me from it. If i wasn't in a public place, i don't think i could've stopped until she did.
Haven't been able to stop thinking about it since. Im convinced canine french is about the best zooey thing there as far as im concerned, and i desperately wish i could try on a species im more into, like coyotes... without getting my face removed.
Though i heard intense tongue kissing is how wolves bond, even with humans...
