i knew a st, bernard bitch that belonged to a friend of mine that i worked for occasionly one day i was alone with her in the garage i was sitting down on the steps .she came up to me wagging her tail and slobbering i had never thought about her sexually before ,but as i petted her my hand strayed down her back ,under her tail to her pussy my god it was huge i started fingering her and she started humping. many times after that when i was over there she would come up to me and squat i would get behind her wrap my arms around her reach between her legs find her pussy hug her to me and finger her and shewould hump like crazy she is gone now but i will always remember her

i my dog does it all the time but shes not spayed

I know someone with an intact female pug that will hump anything she can. Your arm/leg, a stuffed animal, etc.

My girl humps like there was no tomorrow when I masturbate her. She also likes to mount my shoulder. But yeah, she positively is a bitch! ;-)

Actually, a lovely, spayed Brittany Spaniel who did this is the reason I was introduced into zoophilic thoughts in the first place. I didn't understand why at first, but she'd crawl up in bed with me (not unusual), and occasionally stand on top of me and hump. Always thought she was begging to be let out until I wizened up to what was actually going on. Even if we were both crashed out in bed, simply my rolling over to pet her or shift to get comfortable would entice her to pounce on top of me and hump away. Needless to say, I didn't mind this in the least, though she shied away from penetration. Rubbing, licking, and grinding was always more than enough. ^_^ Kudos on a pleasant-memory-inducing thread.
