Jacob had just had a great time pounding his former owner's new horse pussy and now wanted to see how human pussy felt. Kelly had made it most of the way out the door when Jacob wished for her to be naked and tied to the floor infront of him. She then found herself staring at the stable ceiling with arms and legs tied apart bareing her naked body to her father's lookalike. Jacob then squat down between her legs until his horse balls had touched the ground and his cock rested on her stomach. It was so large compared to her that its head rested just past her budding breasts. Kelly tried to squirm away from the huge cock but her bonds were tight and all she succeeded in doing was rubbing her breasts against it much to the delight of its owner.
Jacob quickly wished that the former Mr. And Mrs. Perth would watch and then prepared to enter that tight human snatch. The two new horses stood at rapped attention as Jacob backed up and positioned the huge head right at her dripping entrance. Kelly continued pleading for her father to stop but when the head of the cock kissed her lower lips she stopped her struggling and her only protests where auditory.
Jacob used to the larger and more flexible horse pussy thought he would be able to force his way into the girl but when he tried he only succeed in mashing the head of his cock into her crotch squishing her clit and labia together. After a bit of this he realized that he wouldn't be able to actually penetrate her without doing some long term stretching to her pussy. To side step this Jacob simply wished for Kelly to be stretchy enough to both take his cock and not get hurt by the process.
The wish didn't leave any visible signs and Kelly noticing his stop of his assault on her crotch began saying that she knew it wouldn't fit and that he never should have tried. If Jacob had listened closely to her words he might have caught a slight bit of disappointment in her tone as she said it but he had made his wish and was ready to try again. This time he was more slow with his approach and made sure the center of his huge flared head was directly over her entrance and pushed hard. Kelly was about to say that it was no use it wouldn't fit when she felt herself begin to accept it. With wide eyes Kelly and her parents witnessed an inhuman stretching then a pop as the head entered into her tight depths. The sensation was so intense for Kelly that her mind went blank and her face distorted in to a wicked ahegao.
Jacob held her like that with just the tip in for a brief time but when her moaning turned back into intelligible speech he began to push deeper. It was quite the sight to watch the huge pillar of cock disappear into the young girl and and its bulge start traveling up her torso. The whole experience was just a bit too much for the girl and she found herself constantly orgasming on the monster that had no right to be able to fit in her and switching from human words of incredulity and assurances that this would break her to animalistic moans of pleasure. For Jacob the sight and experience were perfection as her body succumbed to his dominance giving him untold pleasure. He just worried that he would blow his load before he made it balls deep into her. With a concerted effort from him he ignored her sounds and the constant spasming of her body around his cock and he gripped her hips and used them as leverage to shove the last few inches into the girl leaving the crouches pressed into contact. The sensation was finally too much for him and he began to ejaculate.
The state that Kelly was left in was one of deep seated exhaustion and deep seated satisfaction laying on the ground with her pussy gappping and leaking thick horse cum as more of it rested in her womb.
Jacob would need some time to rest but he was already thinking about what he would do next.
