Sarah was alone in the house, her little brother was staying with friends, her parents were out for the evening and not expected back for a long time and her big brother had left home a few days before to join the army as a military police man. For the entire evening it was just her, the tv set and the family dog.
She was watching the film Seven which starred one of her favourite actors, Brad Pitt. She watched up to the scene where a prostitute is tied to a bed and killed, the film scared her which bizarrely made her feel good. Sarah rewound the brief clip in which the prostitutes body is shown tied down, again and again to see as much as possible. The thought of being so helpless that you couldn't stop somebody doing with you as they liked started to play on Sarah's mind. She felt the tingling between her legs and her juices beginning to flow. Images of herself tied up at the mercy of a strange man flashed through her mind, they were quickly replaced by a story she imagined happening.
Sarah was stood on a street corner, a man pulls up next to her and she bends down giving him a clear view of her 38 A chest, she asks him if he wants her. The man does and she quotes him some prices - £10 for a blow job, £20 for straight sex and £25 for anal - Sarah makes the prices low to show what a cheap dirty slut she is. The man wants oral and straight sex so Sarah sits in the passenger seat of his car and the man drives off. As he is driving Sarah leans down to his lap and deftly unfastens his trousers pulling out a big hard cock which she quickly begins to suck. When the man has cum in her mouth she sits up and waits for him to stop the car. They pull up outside a dark derelict building, she asks where they are the man asks why she cares, Sarah says she doesn't. As the man is kissing her and fondling her pert little breasts the car door opens and Sarah is dragged out. A big man throws her over his shoulder and carries her into the building, he drops her onto an old beaten up settee and quickly pushes his hand up her skirt and into her pussy. She struggles and protests but feels only a hard slap on her bum as an answer. By now she is bent over the back of the settee, the driver of the car is behind her with his fingers inside her pussy and the man who carried her in is now standing in front of her with his dick pointing at her face. Realising that she is theirs now Sarah allows the man to slide his cock into her mouth and fuck her face. The car driver pushes his cock into her pussy, he feels uncomfortably big in her unlubricated hole but she takes her fucking without complaint. The second man lays her on her back and has her vaginally as well, after that the two men take it in turns to fuck her slim young body until the Sun comes up the next morning when they leave Sarah on the settee shagged silly.
Coming back to reality Sarah realised that she had missed most of the film and that she was now incredibly horny. She pulled her hand out of her jeans and ran upstairs to her bedroom. She opened the curtains and turned on all of the lights before stripping herself naked in front of the window. She always liked to do this safe in the knowledge that the nearest neighbours were a good mile away. Holding onto the window frame with one hand she stroked her whole body, paying particular attention to her 38 inch A cup breasts wishing that there was somebody in her room to kiss and suck her nipples. She stroked her thighs and opened her legs ready for the moment when she would slide her hand between her legs and stroke her pussy. After a few minutes of toying with her clitoris Sarah had to go to her bed and lie down while she played.
Each time Sarah re-ran her fantasy in her mind it became more explicit with new actions being added every time she went over it. At one stage as she tugged at her light brown hair whilst nearing orgasm she imagined being pulled into the derelict building only to discover that the people in the room were all her ex-boyfriends with her current boyfriend watching as they took it in turns to fuck her in every hole she had.
Whenever Sarah came close to climaxing she would stop for a few moments to calm down before continuing, sliding two of her fingers inside her pussy while the other hand stroked her clit her tweaked at her nipples. Sarah masturbated regularly but this was only the second time she'd gone for a marathon session like this, teasing herself by not letting herself orgasm knowing that when she finally did cum it would blow her mind and she wouldn't be able to move for a long time afterwards. Her feet were resting against the very edge of the bed, in her excitement Sarah had moved gradually further down the bed as her hips moved against the rhythm of her fingers inside herself.
Again she was close to cumming, this time Sarah only managed to stop herself a couple of seconds before the pleasure consumed her body. With her eyes closed and oblivious to the world around her Sarah pulled her hair with one hand and sucked the juice from her other hand as she waited for the first spasms of orgasm which were pulsating within her pussy to subside so she could carry on. As Sarah sucked her fingers clean her hips still thrusted against the fingers which were know in her mouth and she knew that it would not be long before she was unable to stop herself and would be forced to give in to the orgasm which she knew was near.
Just as Sarah was calming down she felt hot breath between her legs. At first she thought it was just a part of her fantasy running away from her, then she realised that it was real! Her mind, still spaced out and sluggish from the barrage it had received took a long time to cope with the information. By the time she had thought to open her eyes and look down a rough tongue was licking at her enlarged clit and dripping fanny. She was taken by surprise and again hesitated just long enough for her body to close in on the orgasm it craved for. It felt so good that Sarah didn't want to look in case whoever was eating her out stopped. She allowed it to continue for a few moments but the tongue lapping at her was too intense and she couldn't help but look down. The sight that greeted her made her mind spiral back into confusion. Instead of seeing the hunky sex-god she hoped for, or the frightening burglar/rapist she expected Sarah saw the families dog lapping at her tight wet pussy.
It was wrong, it had to be - but it felt so good.
'Duke,' Sarah called. The dog looked at her, she repeated his name not sure which command would make him stop, not sure if she wanted to make him stop. The second call made him bark at her. Duke jumped onto the bed, just his front legs but he was a big dog and without effort he was face to face with Sarah. Stretched out as he was Duke was six feet and seven inches long, weighing about 10 stones the 15 year old, five and a half foot eight stone Sarah was no match for the big German Shepherd. She tried to push him off but couldn't do it, the dog was licking her mouth so she couldn't shout at him.
Sarah stopped struggling and allowed Duke to lick her face. As she lay still Sarah felt something pushing against her tight virgin pussy, it took a moment for her to realise that it was Duke's cock. In a moment of madness she reached down to stroke his dick. She touched the dog's balls making him lurch forwards. His cock pushed its way into her body and the dog started thrusting into her, not in the way she expected a man to thrust, this was much faster. Sarah yelped as he entered her and sighed in relief when the dog stopped licking her face.
Duke adjusted his stance, positioning his front paws around little Sarah's waist. With each thrust he pulled her body closer to the edge of the bed and so impaled her more on his cock. Duke's movements slowed for a moment and Sarah thought he must have came already, his claws dug into her hips as Duke pulled Sarah still closer, this time a much slower and more deliberate thrust accompanied the pulling. A lump entered her pussy, at first it hurt and Sarah screamed loudly enough to make Duke stop for a moment. But even as the scream died in her throat she felt something even more painful. Duke's cock was actually growing inside her, each time the dog pushed into her his cock seemed bigger than before. Sarah managed to get her legs under Duke's hind shoulders to push him off of her, she'd liked it at first but now he was hurting her. With all her strength Sarah managed to lift his hind legs from the floor and push the big dog back a little, all the while his cock was growing inside her young body. She felt the lump moving closer to the lips of her pussy, that lump had grown too, it hurt a lot and Sarah realised that it had grown too big to come out of her without Duke's help. She stopped struggling and accepted that she had lost her virginity to her pet dog and that there was no escaping the fact that he was going to fuck her whether she liked it or not.
Duke pushed his big shaft back into Sarah and carried on pumping his cock into her. It carried on growing until Sarah could feel it pushing into the pit of her stomach. As she relaxed and allowed Duke free reign over her Sarah found herself back on the sexual high she'd been experiencing a while ago.
Closing her eyes as the orgasm she'd deprived herself of earlier swept through her body making her sit up as far as Duke would allow. She hugged his neck and kissed the fur around his throat. When she fell back too exhausted to stay up Duke started licking her face again. This time Sarah opened her mouth and let him do as he pleased. She could feel the saliva dripping from Duke's mouth into hers, it felt good to be so completely fucked like this. Too exhausted to move Sarah felt another orgasm forming within her. When the second climax hit her Sarah just lay back panting, staring at the big dog that was fucking her.
Sarah came again and again until she thought that she would surely pass out in a few moments. Inside her she could feel Duke's cock throbbing, the throbs became powerful spasms and Sarah eventually realised that he was cumming inside her. When Duke finally finished shooting his load into her he began a little dance with his hind paws and after a long while his cock began to deflate enough for him to withdraw from Sarah. Duke left the room immediately and padded down the stairs where he fell asleep. Sarah couldn't move to stand, instead she lay on the bed feeling her pussy, even now the dog had withdrawn her hole was still wide open. She rolled onto her side and curled up a little, just out of curiosity Sarah slipped her fingers into her cunt. She wanted to see how wide Duke had forced her open, one by one she slipped all of her fingers into herself after a few minutes her entire fist was buried inside her cunt. Pulling her fist out she licked it clean, her juices tasted different, she decided that it must be the dog's cum that gave it that flavour.
Sarah fell asleep on her bed for about an hour, when she awoke there was a large wet patch on the bed where Duke's cum had seeped from her body. Slowly she got up, changed the bed covers and put on her night-dress before climbing back into bed and sleeping until well into the next morning.
