I had woken later than usual because it was Sunday and I planned to have a lazy day, free of writing. I swung my legs out of bed, then caught sight of my reflection in the robe mirror. I shook my head because the dream I was having was still clear in my mind. I had been dreaming about my Great Dane, Lady, who passed away a month earlier. It was the fifth or sixth day in a row that I had experienced a similar dream, so I was getting worried.

Maybe it wasn't about her, because in the dream, I was a dog running through the forest. I had to thread my way through ferns and long grass as I galloped along on four legs. I was running at breakneck speed and was sure that I was Lady, and that I was being pursued by a male dog.

The vivid imagery was still imprinted in my thoughts. I lifted my t-shirt off, discarded it on the bed, then slipped onto the floor, onto my hands and knees. I didn't take my eyes off my reflexion as I approached the mirror. My long dark hair was mussed and falling around my face, giving me a shaggy dog appearance.

"Ruff!" I barked at my reflexion. God, I thought. I need to get another dog or I'm going to go crazy.

I turned side on and studied my petite body. I was very sleek. My tits were small and firm and my butt pert. Apart from my legs, it was easy to imagine being a dog. Lady was in fact larger than me. I'm only 5' 1" tall and weigh seven stone. It was lucky that Lady was well behaved because she easily bowled me over when we were playing in the garden.

Would I be able to find another docile Great Dane? Or, if I got another dog, should I get a smaller one? My attention turned to Lady's dog basket, which had always lived in the corner of my bedroom. I had heaped all her dog paraphernalia into it, even the items that I had used to train Lady when she was a puppy. I hadn't plucked up the courage to dispose of the gear because I had lingering thoughts of replacing Lady with another puppy.

Staring at the leather items, I imagined myself wearing the collar and muzzle and crawling around the room pretending to be a bitch like Lady. Just thinking about it made my lower belly sparkle with arousal. I picked up the collar and offered it to my neck. It just fitted on the last hole.

I buckled it and returned to the mirror to see if I looked more like a bitch. "Ruff, ruff," I barked at myself.

I sat back on my heels and as I did so, I parted my thighs. My eyes lighted on a small damp spot that was appearing in the centre of the gusset of my pink cotton panties. The fantasy that I was developing in my head was making me wet - very wet. I raised my butt and pushed my panties down to my thighs, then worked them off altogether.

I stroked the entrance to my quim, then smeared the creamy fluid up my tight cleft. I pushed deeper so that I could rub my clit a couple of times. I was seriously in need of sexual satisfaction. I had a friend who could help me deal with such emergencies. I kept him in the bottom drawer of the chest under the window.

I crawled across to the chest and pulled the drawer open. I kept my friend hidden, which was ridiculous because I lived on my own. After fishing the black dildo out from under my clothes, I returned to the mirror to prepare for synthetic sex, which was far less complicated than finding a man capable of satisfying my demanding taste.

I normally used the ribbed dildo, which had a suction cap on the end, in the bathroom. The idea to stick it to the robe mirror had come to me while I examined my petite, sleek body in the robe mirror. I had often wondered, when Lady was around, what it would be like to be a dog instead of a human. Taking it from behind was one way to enjoy the fantasy.

I made sure that my bare feet were up against the mirror to stop the door from opening, then wiggled my ass until I felt the dildo's blunt crown nudge my soft, unresisting entrance. Although the dildo was 10" long, I didn't plan on using all of it to satisfy my hunger for a release of the tension my Puppy-girl fantasy had generated.

"Oh, yes," I said softly as I felt the ridges on the dildo ripple against my vaginal walls with each mini thrust.

It was a heavenly sensation when I was in control, rocking my body back and forth with a steady rhythm, pushing deeper with each exploratory plunge. I noticed straight away that the sensations were more intense than usual which spurred me on to increase the speed of my backward lunges. The sparkling sensation intensified until it morphed into the mother of all orgasms.

"Oh, fuck," I muttered once I was rocking back and forth on every inch of the silicone cock that was available.

With my butt cheeks nudging the glass at the end of the stroke and my sensibilities ablaze with fizzing energy, I discovered that when I dipped my back like a real bitch, I could get another inch...

"Oh," I gasped when I felt the dildo's crown nudge my extremity. It was a new experience for me and one that would take a bit of getting used to.

I was tiring, so having sated my hunger and fulfilled my dream, I rocked forward and crawled away from the dildo. I had enjoyed myself but, on another level, I knew that I would never be able to experience the real thing.

I showered, then wearing just a dressing gown, I prepared a bowl of cereal and took it to my office. After turning on the computer, I sat and stared at the screen while I ate. I decided to research canine fantasies on the internet.

It didn't take me long to find websites with pictures of girls, around my age, 25, strapped and bound, while strutting around on the end of a leash. Their 'owners' were usually huge, aggressive men with bulging muscles and tattoos along their arms.

The cruel 'owners' were usually wielding crops or straps and in one video clip, which I saved for masturbation purposes, one guy gave his bitch a real thrashing. Such masochistic treatment scared the living shit out of me for I had never been beaten in my life.

I wondered, if in general, Puppy-girl sex has to involve violent behaviour when participating in a group, like in the clips the screen. And, was it necessary to submit to such treatment to experience and enjoy the fantasy?

I found a few sites devoted to simulated doggie sex with men and women playing the roles, but it was mainly fun situations rather than serious bondage and confinement. I also found plenty of sites selling the gear to transform a willing devotee into a strutting bitch, but the items were only any good if you had a partner willing to join in.

Living on my own had its drawbacks, but my ground floor flat was definitely an asset for what I had in mind. If I was going to try out my fantasy, then I would have to get some gear from the specialist sites. However, after thinking about it, I didn't see a way in which I could completely do it on my own.

It was the thought of being stuck in the role of being a bitch for a day or a weekend that really turned me on. It was a puzzle that I was determined to work out, no matter what. I needed help, but the guys I knew were pathetic and my girlfriends would choke on their Caffe Americanos, if I confessed my Puppy-girl fetish to them.

There was one girl at work, who had admitted to me that she liked being peed on, but I didn't know her well enough to trust her with the revelation that I wanted to be a bitch for the weekend in the safety of my own flat.

Another friend admitted that her boyfriend was turned on by sniffing and wearing her soiled underwear. It was brave of her to tell me about it, especially as I'd met the guy a couple of times. It was an odd fetish, but it wasn't anywhere near as kinky a fetish as what I was experiencing.

The other thing about owning a dog, was the regular visits to my local vet. I missed the interaction I had with Doctor Cortney who was both hunky and handsome. He was though, a bit of a flirt and I had a devil of a job to discourage his interest in me.

The problem may have been me because I have always been attracted to black guys. My one and only serious boyfriend was black, but he was a bit of a lad and ended up two-timing me. I caught him snogging the girl at a party, with his hand up her skirt, so that was the end of our relationship.

Thinking about the attractive black physician finally helped me to focus on something else - my book, where one of the main characters was based on the vet. I had promised myself a rest day, but after opening the word file of the script, I was sucked into the story and there was no looking back...
