As scared as Bryan was about the powerful animal instincts, he was also very curious. He had chosen to become a bull, even if he had not intended to have it go this far. Could he really ignore the intense need, the animal instincts that were hammering at his willpower? If he did manage to get himself restored, Bryan knew he would forever regret not taking advantage of this opportunity. And if he was stuck as a bull? Well, he might as well start enjoying the benefits while he could.
The decision made, he relaxed and let the bull's instincts show him what to do. However, he had underestimated the strength of the mating instinct - desire flooded over his thoughts, and Bryan the human was quickly consumed by the bull identity. It was a bull that pressed against the cow's flank, a bull that shoved its massive body up and over the cow's rump, and a bull that penetrated and drove deep into the slick, hot cunt. The animal thrust hard, jetting semen into the female almost immediately, and withdrew after only a few more pushes. Its massive testicles were not emptied - it had completed the ritual and was blindly satisfied.
Bryan regained some conscious thought. He felt dazed, satisfied, if somehow disappointed. That's all there was to it? Oh, the ejaculation had been intense, but not with the pleasure he had expected, and certainly nowhere near as long. Sex had taken seconds. He'd passed his seed - the bull had accomplished its purpose. And it was ready and able to do more, perhaps many more. There were other cows ready for him. In fact, he was already slowly shuffling towards another female.
