Shadows Den

She knew it was almost time for him to get home from work so she placed her collar and leash on and inserted her tail and waiting on her hands and keeps at the door waiting for him. She heard his car as he pulled up her excitement grew as did the dampness between her legs. The door opened painfully slowly as she sat there with her leash clenched between her teeth she couldn't help but wag her ass and tail with excitement. She met his gaze as he entered the house she had been trained to wait for permission to move when he came home and she did just as she was trained. He smiled and softly praised her "Good girl" as he patted her head and then took the leash from her, to lead her into the living room. He sat down on the overstuffed sofa as she took off his shoes and socks and rubbed his feet for him. She smiled at the sight of her in her collar and the tail as it wagged excitedly. He instructed her to unzip his pants and to suck his cock until it was hard she did just as she was told without hesitation. As she sucked his cock she looked up into his eyes, without saying a word to her he gave her more praise and she could feel herself growing even more wet as it slowly leaked down her inner thigh. He took a handful of her hair to control her movement as he forced his cock into the back of her throat he could hear her gag slightly but he did not care. She was just his pet and he would do as he wished with her. Before he shot his load of cum into her waiting greedy mouth he stopped her. He smiled and said I have a surprise for you tonight my Pet. She looked at him both puzzled and excited what surprise could he have for me she thought. He lead her on all four to the bed room where he cage was that she slept in sometime when she had been bad (she secretly liked sleeping in the cage at times it made things feel more real to her) he walked her over to the bed and reaches under the bed and pulled out a couple boxes one larger box and one smaller. He asked her if she was curious about what was in the boxes she whimpered and nodded. He opened the small of the two boxes and it was a dildo unlike any she had seen before it was larger then she was use to and near the base was a large swollen area. She looked at it puzzled as to what it was she looked at him and without saying a word she questioned as to what it was. He explained since she was his pet she should know what it was like to have a cock that would match her inside of her. She blushed when she realized it was a model of a dogs cock and it would be used on her. She glanced over at the larger box with a bit of nervousness and curiosity as to what would be in the bigger box she noticed it was heavier then the small box. He noticed the look on her face and asked would you like to know what is in that box? She blushed and wagged her tail a bit as she nodded yes. He opened it up and it was something they had talked about before but she never thought would have one. It was a machine that a dildo would be attached to and used to fuck her. She could feel her self gushing more with excitement at the thought of being restrained and fucked by this machine which would not get tired and would be fucked as long as he wanted her to be. He quickly fastened her ankles to a spreader bar and then placed one on her wrists as well then fastened the two bars together so she could not move. He placed a gag in her mouth in the shape of a bone then blindfolded her. He sight now gone and her ability to speak taken away as well she grew more excited her mind raced what is he going to do, she could hear movement but could not see what was going on. She could feel movement behind her but was unable to move. Soon she could feel his large hands softly rub her now soaking wet pussy as he slid a finger inside she gasped. She could feel something behind her pressing at the opening of her pussy she knew it wasn't his finger this was larger. Soon what it was slowly pushed into her pussy as she struggled trying to gasp as it pushed deeper inside and seem to not stop. It was then she felt it grow in side as it pushed against the outside she knew in a flash what it was he was using the dog dildo to fuck her she struggled to push back onto it wanting more inside of her to feel like a true bitch being bred a soft moan escaped her gagged lips. Soon it became all to clear he was not controlling the dildo with his hand he had it on the machine and was slowly increasing the speed as the speed increased she struggled feeling as if she was going to be knocked over by the trusts of the cock deep inside of her waiting dog pussy. She moaned and begs as best as she could to give it all to her she wanted to feel it fill her up totally. She could feel the knot pressing and pushing in pressing on the thin skin between her pussy and her ass where she had a large tail inserted with a plug on the end to keep it in place. This feeling grew until she was ready to lose her mind she felt like a true dog slut being used over and over as she came. She could not stop it as she had no ability to speak or use her safe word (not that she would) the machine seem to drive home harder and harder. He told her I want you to count in your mind how many times you cum for me then when were done you tell me do you understand me? She nodded half in bliss and half just wanting this to never stop. She started counting in her mind it wasn't long until she lost count. After what seemed like forever being fucked and used by this machine she could feel it being pulled out as she whimpered and wined. She could feel his cock drive deep in replacing the machine as he grabbed her hips and thrust deep inside of her. He fucked her like she had never been fucked before it was not like a man would fuck a woman but more primal (almost animistic) at one time right before he came he leaned over and softly growled in her ear and said in a deep husky voice this is my bitch and I will breed her myself and fill you full of my cum with that he thrust harder and faster as he shot his steaming hot load of cum in her well used aching pussy. He unfastened her and removed the blindfold and the gag. Now how many times did you cum? She blushed and replied I lost count. You lost count? Why did you lose count? It was the thought of being used and fucked like that it made my head swim and I was over come with the feeling. He smiled as he pulled her close and ordered her to clean his cock off with her mouth.
