So for the next few weeks, they followed the plan while going ahead with their normal routines. During the day, they would practice restraint, while at night they would determine the Minotaur's routine with the Faun; the last part was easy. The Minotaur always went to the cornfield, but the Faun would only show up every second or third day; luckily the location was consistent.
The restraint however, was much more difficult as Drew did most of the Centaur cum collection. Derrick did his best mind you, but more than once he swallowed it unknowingly, and there was a particularly hilarious time when he snorted it out his nose. It was ok through as they had more than enough, the entire exercise was just to get Derrick to practice restraint.
Finally, in two weeks in they were ready to act. Sneaking into the Minotaur's hut was especially easy, as nobody dared to touch his food; he simple wouldn't expect it. Mixing the thick creamy bovine milk that that he normally drank with Centaur cum was a piece of cake. If it would work through, that part was unknown. They needed to get to the cornfield without being noticed so they had no intention of sticking around to see if it affected the Minotaur, least they become the target of an overly horny bull.
Then they made their way out to the corn field and waited. Drew had long stopped being religious, but he prayed nonetheless to whatever would hear him. As the minutes passed, he drew deep sharp breaths. What if tonight the Faun wouldn't come? What if the cum had an unexpected effect on the Minotaur, or didn't work at all? His mind ran through all the scenarios as they waited under the cool starlight sky until he heard some movement. They had used the utter balm earlier to clog their noses so they couldn't smell the goat musk, but guaranteed it was the Faun; he could recognize that small frame and tight goat ass anywhere.
Nudging Derrick briefly, he got ready and jumped out; grabbing the Faun from behind.
"Oh no!" Screamed the Faun, "Please don't take me" he said sarcastically as bent over slightly to better the angle for what he thought was the Minotaur as powerful hands held on to him from behind.
Being this close, Drew did everything he could to focus before loosing his mind to the built in submissive nature all gingers had to Fauns, and quickly shoved his equine dick into the goat ass in front of him. It went in easy... surprisingly easy. The Faun seemed to have pre-lubed himself in anticipation for his bullish lover, but there was something different about this.
The Faun's eyes opened wide, but not in pain; it was in recognition. "I know that dick!" he exclaimed, before pushing back against his attacker. Drew was caught off guard as the Faun hilted himself enterally on his equine cock, then closed upon it like a vice before the Faun let out a giggle.
"You thought you could catch me unaware? Maybe escape your form?" the Faun teased. "It might have worked if you know what you were doing" he calmly explained. Looking behind him, he took pleasure in flexing and relaxing his anal muscles with expert precision. Drew find himself trapped, hilted up to his balls he couldn't escape at all as his dick was being milked by the Faun's muscles; his eyes rolling backwards in pure submissive pleasure.
The Faun for his part just grinned. "Too bad through, if you could make me cum your simple plan might have worked" he bragged. "Instead, I think I'll just milk you dry and reduce the size of your dick to a tiny nub my ginger stable ha..."
Suddenly, out of the cornfield Derrick joined the duo. Catching the Faun in mid sentence, Derrick took his hand and smeared it into the Faun's face, coating it with a generous dose of Centaur cum. As the Faun's eyes went wide, Derrick then got down in front of the Faun and wrapped his lips around that delicious goat cock, sucking for all his worth.
The Faun, sputtering the potent Centaur cum screamed "NO!" as it's effects immediately brought his goat cock out of his sheath to full mast. Between Drew fucking the Faun, Derrick sucking the goat cock for all it's work, and the Centaur cum in his mouth, even the experienced Faun couldn't hold back. Derrick efforts was rewarded as the thick ropy strands of salty goat cum he grabbed so deeply surged down his throat; way more than he remembered before.
Then, behind the Faun where Drew once stood, there was a second Faun; exactly similar in every respect.
"YESSSS!" Screamed Drew, as his mind cleared.
He could instantly feel the transformation powers of the Faun. "I WAS going to be nice", said Drew, as he found he could now pull out and thrust again; the Faun's muscles could no longer magically hold a dick of equal power, "but I think I liked your suggestion better."
The Faun then started to change. Slowly at first, but quicker and quicker into an inventory ginger stable hand but with one notable difference; he had but a tiny nub of a dick that looked vaguely equine.
Derrick on his part, felt the change in his mouth happen, as the dick got shorter and shorter before popping out. The new ginger, exhausted by the change, passed out in the field as only Drew remained standing, admiring his new body and the power it possessed.
Derrick fell back on his ass, full of salty Faun cum and feeling now attracted to Drew.
Noticing this, Drew walked over to him and kneeled before him. "You were amazing Derrick, where did you keep that Centaur cum? That was perfect! I couldn't have done that without you."
Derrick just looked at Drew with a glazed look in his eyes before Drew seemed to realize something.
"Here, this will help" he said, and leaned in to deeply kiss Derrick, using his new magic to undo the submissive ginger nature. Stepping back up, he ran his hands along his well defined Faun legs and flexed. "Wow, this feels so... sexy." he commented before turning to Derrick again.
"Well, how can I thank you? I can change you into anything you want Derrick, just name it!" he smiled, waiting for an answer.
