Once they arrived at Katie's house, she let John out of the car. He bounded out happily with energy he couldn't explain. John decided to pass this off as part of his transformation. And all Katie could do was laugh a little at how much John was acting like a dog.
Katie then openned the door to her house and called to John. He responded by walking into the house, and then licking Katie's face after she had closed the door. Katie laughed some more and said,"Well, if I didn't know any better, I would think that you are enjoying things now. I just hope you stay this excited for your surprise."
"That's right", John thought, he got so caught up that he forgot that Katie had brought him here for something. But what was it? "Ok", Katie started again,"you go to the bedroom and wait for me while I get your treat ready." This had John really baffled, but he decided to go anyways as he really wanted to know what Katie was upto.
Inside the bedroom John leaped onto Katie's bed and sat down. After about 2 minutes he heard Katie comming into the room. What he saw next really suprised him. It was Katie, and she was completely naked except for a leather jacket on her back. Katie then shut the bedroom door and began to explain,"Ok John, look, for awhile now I have been looking on the internet about beastiality and other things. I really have never told anyone this, but I have always wanted to make love to a dog. But after you got turned into one I figured this was the best time ever to try it out. And I know as long as we have been together we have never gone all the way, but I promise you, after the 24 hours are up we can do whatever you want if you just do this for me."
John was in a state of shock. Just now his girlfriend had admitted to always wanting to try sex with an animal, and now she wanted to try it with him. He knew he had always wanted to be with her, but he wasn't sure if he wanted her like this. But when he looked into her eyes, she had the most hopeful look that he just couldn't say no to. So as an indication of his decission, he barked once and stood up.
"Oh thank you John",Katie said, warping her arms around his neck,"I promise that you will love this as much as I will." John wasn't sure if she was right, but he didn't have much time to think as she went right for his sheathed member with her mouth.
John felt as she stroked and coxed his member out with her tounge, and it felt great. It was almost as if his new doggy part was more sensitive than it was when he was human. Next Katie began sucking and pulling on him. Over and over, she did this and John had to admit, Katie was right about the whole pleasure thing. He felt himself building up, and getting tense. Finally he released he first ever batch of dog cum into his girlfriends mouth. He had never had such a powerful orgasm.
Next Katie got up and got on all four. She waved her ass about to show John she was ready. But he knew this already, as he could smell her with his new nose. So John rose up, but did not mount his girlfriend. Instead he started licking her again and again. This drove Katie wild as the feeling of his tounge felt so good across her lips. He continued to do this until she shudder and had an orgasm of her own.
John licked up her juices, but as he did he heard Katie say,"Ok, enough with the foreplay already, I want you now!" And with that, John stopped licking her and leaped up on her back. He began humping around, trying to find his point of entry. Thankfully though, Kaite who had done her research on the whole thing, reached back and grabbed him. Then she guided him to her pussy and waited.
As if prompted by instinct, John thrust in as soon as he felt Katie's lips touch his rod. But with one thrust John felt himself break though something inside of Katie as he plowed deep inside of her. "Did I just take her virginity?" John asked himself. But even as John began questioning whether Katie had planned for a dog to take her virginity or not, his body continued to pump into her.
Katie on the other hand, while she did experience a moment of pain as John took her virginity, she was now feeling more and more pleasure as she began to loosen up. Over and over again he humped wildly into her, and she loved ever moment of it. She could not believe that she had denided herself of this pleasure before because she was scared. But now she was pushing back with her own body as she felt him start to grow even larger in her.
John began feeling this too, as if some sorta preasure was building up at the base of his penis. But even though it was there, to both of their amazement, this part too entered Katie. And while John, not knowing much of canine anatomy, Katie new that she would soon be tied to her lover.
After a couple more thrust, John could no longer move as his tie now completely filled Katie. And with that, he began to shoot his doggy load into Katie, much more than before. In addition with this, Katie seemed to exploded into the greatest orgasm she had ever felt. With each shot John fired, Katie seemed to orgasm more and more, until the two, both very tired, laied down on the bed, still tied together, and pass out into a sound sleep.
