I'm more than a little confused by my own response to the events in this story and hoped that writing it would help me understand my feelings a bit more. Part of me feels like a dirty slut but the other part of me is incredibly turned on about how slutty I can be!

I'm a 29 year old woman and have always considered myself to be fairly normal in terms of sexuality. I've had a fling with a girlfriend but aside from that I've had a few boyfriends and never got into anything too kinky or strange. Until this happened…

My boyfriend and me were having a lazy day in bed. We had been out to a party the night before and after drunkenly fucking had fallen asleep. My boyfriend was not always particularly nice to me – my girlfriends all said I could do much better – and he was often bullying and domineering. I think he liked causing me, well if not pain, then discomfort. I'm quite a petite woman, small and slim with small breasts. I've certainly never gone in for size as too big a cock can be uncomfortable but my boyfriend would love to fuck me hard or try to make me gag on his cock if I was sucking him.

Anyway, this particular day, we were drifting out of sleep and I could feel my boyfriend rubbing himself against me, his cock already hard then he moved up over me so his thighs were across my shoulders and his cock was looming over my face, wanking himself and saying he was going to cum all over me. I played with his balls and told him to fuck me. He made sure I sucked his cock first, making it all wet and slick with my tongue as he tried to fuck my throat.

Finally he knelt behind me and had me on all fours as he thrust his hard cock into my pussy making me grunt as he fucked me deep and hard. I wasn't even very turned on as he basically satisfied himself and then came inside me with a loud moan. I could feel his cum inside me as he flopped down on the bed. I lay down next to him and started to drift back to sleep only to be disturbed by his dog whining and trying to get up on the bed with us.

The dog's name was Jagger and I realised that he was sniffing around me obviously smelling sex and my boyfriend's cum. I pulled the sheets up over me and pushed him away. My boyfriend was laughing and teasing, telling me to let the dog have a sniff. Jagger whimpered slightly and took himself off to the bottom of the bed and lay down and starting licking himself – his cock slowly growing from his furry sheath.

"Now look what you've done! You've given Jagger a hard on!" said my boyfriend. "It's only polite you help him out" he joked. Or at least I thought he was joking.

As we lay there he kept on saying I should attend to Jagger, teasing, joking, pleading and almost demanding. I was dismissing it all but must admit to starting to feel a little tingle as I imagined doing something so depraved. I couldn't could I? My boyfriend was rubbing my little breasts and squeezing my nipples telling me how he'd like to see me playing with Jagger's big dog cock. How he'd like to see that more than anything else.

My mind was in a rush. I was feeling more and more turned on, seeing Jagger licking his huge red cock, my breasts being rubbed, the wicked thoughts of little old straight-laced me having sex with an animal. Oh My God! It was too much!

I crawled down the bed and called Jagger timidly. I don't think my boyfriend could believe I was actually going to do it. Jagger came over to me excitedly, sniffing me. "Let him lick your cunt," said my boyfriend.

"Here boy," I said, guiding Jagger to me as I lay back on the bed.

Jagger wasted no time in sniffing and licking at me. His tongue brushed against me and felt incredible. Jagger was licking and tasting the mix of cum and my own increasingly wet cunt and loving it. So was I. I had never had oral sex this good. That big wet tongue slobbering over me made me so wet and so turned on and the thought that I was being such a dirty slut, letting A DOG lick me there was making me more and more turned on.

I thought I was going to pass out as my orgasm ripped through me and I screamed out loud. I think Jagger was frightened and jumped up as he heard me. I patted his head and told him what a good dog he had been. My boyfriend urged me to touch his cock and I carefully and slowly slid my hand down, stroking his fur as I did.

I wasn't sure if he'd bite me or jump back in fright to feel my hand on him so I very slowly slid my fingers to his cock which was still hanging down red and swollen. I was surprised at how wet, how slimy his cock felt as my fingers reached it. It was so warm and so big in my hand as I slowly started to wank him.

Oh my god! I was lying with a dog's cock ad loving it.

My boyfriend was harder than I had ever seen him and was stroking his cock as I slowly stroked Jagger's big cock up and down, right to the huge swelling (I later found was called a knot) at the base of his cock. My cunt was throbbing and I was enjoying being such a slut. I wondered if I could make him cum. I could feel sticky fluid dribbling over my fingers and along my arm as I stroked him.

My boyfriend told me to suck it and like a proper little slut I bent my head down under Jagger and moved slowly towards his big red cock. It looked so swollen and so very big as I brushed my tongue along the tip of his cock. I suppose I expected it to taste gross and repulsive but actually it tasted not too dissimilar to my boyfriend's cum. As I got bolder I put my lips around it and started to slide them up and down over his cock.

It sounds weird but I was so turned on and so wanted to please Jagger with my mouth. I could hear Jagger pant as I sucked deeper and deeper filling my mouth with his cock. All the time I could feel warm dribbles of salty liquid oozing from his cock into my mouth and wondered whether this was how dogs came. My boyfriend was more turned on than ever and was wanking himself furiously as he called me a dirty dog-fucking slut.

I heard him moan and felt him shoot his warm cum over my back and into my hair but I didn't stop sucking that big dog cock. My cunt was tingling as I thought about what I was doing. Suddenly Jagger's cock exploded in my mouth and I gagged as his cum pumped into my mouth.

It tasted okay, so I tried to swallow as much of it as I could but it was no use, there was just too much of it. Finally I had to take his cock out of my mouth and it kept on shooting stream after stream of thin, warm dog cum all over me. I felt it on my tits and my face as I swallowed all I had taken in my mouth. I didn't think he would ever stop.

"Fucking hell!" was all my boyfriend could mumble when Jagger finally stopped cumming and he looked at me covered in cum feeling for all the world like the dirtiest girl that ever lived... and loving it!

That wasn't the end of my adventures with Jagger but it certainly started a whole new experience for me and a whole new understanding of what I am like. Perhaps if people like my story I could share more with them.
