Right before Jess left, she added 3 small protective measures. Now she was immune to all damage and diseases, can't get pregnant, and didn't need to sleep. It wouldn't be good if she got harmed durring an orgy, or came down with some nasty STD. Plus she had no intention of mothering a child, at least for now. And if she needed to sleep, it would be time wasted when she could be getting fucked in some sex club.
Satisfied, Jess starts making her way outside. Right as she was about to leave through her back yard gate, her dog tackles her to the ground and begins humping her leg. Jess wasn't hurt at all, only a bit annoyed by her dog's over attachment to her family. He would try to not let people leave whenever he was in a mood.
After struggling to push him off of you, you notice his rather large dick isnt too bad looking. And he is already in the mood anyways, so why not let the pup use her properly. Thinking this, Jess shifts positions into a better one thats more suited for doggy style. Her dog gets the hint and starts fucking Jess.
Jess mind had blanked the moment the dick had entered her pussy. All conscious thoughts were now only of making this dog never stop fucking you. You turned on your vibrators, hoping to make his cock even harder. That's when you felt it though. Something large had grown inside of you. His knot.
Now that you were physically inseparable for the moment, you made sure he emptied all of his cum into you. Every. Single. Last. Drop. it was a solid 40 minutes until he was able to slip free of your pussy, and as you stood up, you felt a rush of all his cum just pour out of your pussy. It felt and looked just like someone popped a water balloon that you had put inside of your pussy. You were a bit disheartened though to watch all of the fresh cum just go to waste. But thats how it is. You had no use for it anyways, and needed the room for other users. However one thing was for sure. You now knew you were meant to be a sex doll. It is your destiny to be fucked by cocks. Even to just service them when allowed to.
