This started as a fantasy, then became guilty obsession, then a reality, and is now my secret lifestyle.

When I was a little girl my parents took our Shepherd Big Boy to a stud farm. I saw him mate with several other dogs and overheard the adult jokes I didn't quite understand. Wandering around the place I even saw a dog being "milked" and the woman doing it sneaking a taste. That was my introduction to the physical act of sex.

As I hit puberty my fantasies sometimes included beastiality but they mostly revolved around being an animal on a leash. I ended up losing my virginity to Big Boy when I was in junior high but that was my only act of actual beastiality and I never had that urge again.

I developed a secret fetish for animal roleplaying and even bought a collar and leash to wear while I played with myself. I filled notebooks with elaborate sexual fantasies of a girl being broken to a man's or woman's will as a sexualized housepet. When I was married I was secretly subscribed to kitten-play and puppy-play websites - I couldn't even tell my husband about my fetish and I was terrified to actually try to live it out.

My husband left me eventually leaving me and my son alone and I kept my secret. Then my son found my old notebooks. He asked me about the fantasies in them and I tried to brush them off. When he asked me point blank if I was a "sex weirdo" I admitted it out loud for the first time in my life and cried.

When I stopped crying, he said those beautiful words I've never forgotten ... "Get off the furniture, girl." I obeyed and brought him my leash in my mouth and barked and he stripped away my clothes and made me his Bitch. That first night was everything I ever wanted with a loving master. That was one year ago at the first of May.

Since I still have to earn a living, we can't do it full time. But we've made Friday "Pet Night" where I strip down to being a Good Dog and playing with my master. The only other concession I make to being a Bitch the rest of the week is that my Master no longer plays with himself because my mouth and hands are available instead.

When I get home from work on Fridays I slip out on my clothes and put on my furry paws and ears and tail and get on all fours and become my Master's Bitch. He's a Good Master to me and we play fetch and romp. He disciplines me when I need it and rewards me for proper behavior and when I do tricks. And when he mounts me or gets out a special toy or restrains me for special games I'm very happy.

I'm anxious for the day when he's a full grown Master and I can become a Bitch full time. He talks to me about renting me out to horny breeders but I'm just a Bitch and can't understand master talk so I just lick him and wag my tail.

My son is very strong and confident and has a girlfriend who adores him. He used to be shy but now he's the leader of his pack. I feel proud of him.
