"That would be great for me - if he goes animal, there is no chance he will be able to tell anyone about the swap." The fake Derrick grinned. "You know we got a complete family swapped out for trees in the dryad grove? Parents, two older kids and a toddler. All mature apple trees. Phil, that hulking satyr with the broken horn? He ended up drawing the short straw and had to be the baby."
The centaur chuckled. "Rough start, but he'll do OK once he hits his teens." Then the centaur pointed at the screen. "Looks like your lucky day. There he goes!"
*************************************************
Derrick shuffled out into the pasture. It felt comfortable being surrounded by cattle, though he also felt very aroused. One of cows nearby was not only in heat, but was eyeing him as a potential mate. There were so many cows! No wonder the few bulls were not challenging him. Derrick looked back towards the opening back to the caves, knowing he really should find management and get this whole minotaur change sorted out. But he liked being a minotaur. And he sure wanted to try out the massive, pointed bullcock and heavy testicles that hung down between his legs.
Maybe just once, to see what it was like. He shuffled closer, nostrils flaring as he drank in her scent. The cow's tail lifted a twisted to clear the way to her huge, slick cunt. Although he had never had sex before, Derrick knew the basics. There was some added drive, though. Bull's instincts? Maybe the minotaur body provided some built-in instructions. Derrick felt the mating drive build. He could have easily resisted, but why? He wanted this, and embraced the animal lust.
The bull's natural instincts did not overwhelm him - instead, it flowed in and around his own desire to mount the cow, giving his curiosity purpose. Derrick knew how to approach the female, and as he got close, how to position himself. Even so, he was not prepared for the sudden and brutal plunge, or the powerful pleasure and total immersion of thought. Derrick bellowed as the most intense sensations he had ever experienced in his life filled his mind completely. The cow squeezed around him and he shifted and plunged deeper. Each thrust became more important than the last, and as he finally erupted inside the cow with a massive gush, Derrick knew absolutely that he had accomplished his primary purpose in life.
He slid off her, staggering both from the residual pleasure and sense of accomplishment, as well as stiffness in his body. It was not painful, just that his limbs did not quite want to bend the way they had before. Derrick tried to puzzle over that, but could not clear his head enough. The drive to breed had been so intense, so pure! Another cow came close, inviting him with scent and rubbing against her. The contact brought renewed pressure in his testicles, and he was eager to experience the overwhelming reward of mating again. The experience lasted even longer this time, and the climax blanked his mind to all but the pure purpose of his being.
Derrick drifted out of this blissful surety of accomplishment slowly, gradually aware that he was standing amid several other cows. The one he had mounted was already moving off, her need filled. He was on all fours - not quite natural feeling or comfortable, but his back and his arms and legs were not responding to a desire to stand, either. That should have been alarming, but he also realized he had gotten much bigger, stronger, more massive. And even more endowed. The weight and pressure of his testicles told him he was more than ready to satisfy yet another female. The sense of purpose had not left him completely this time, lingering as a welcome presence that made Derrick feel important. No - not important. He felt connected, part of the herd, but only as a seed giver. Derrick himself did not matter, only the swirling masses of semen in his swollen ballsack. He thought this was vaguely curious. Shouldn't it matter who he was, what he did with his life? Wasn't there more to existence than providing semen to make more cows?
Then one of the new needy females rubbed against him, and the questions were lost. Derrick felt the surge of lust and welcomed the intoxicating mindset of total accomplishment. He mounted the cow, finding it easier than ever, this third mating lasting longer and cementing the concept of his purpose in life as a seed giver. He and the cow bellowed, instincts in complete control.
