Still hovering, Mark flew closer to Evan. "As a fairy, I must have magical powers, right?"
Evan shrugged. "Whatever, sure."
Mark smiled. "It's time for some fun, then." He pointed a finger at Evan and repeated, "You fucking ass."
There was a bright flash, and Evan was suddenly naked. "What the!" he shouted. He began to reach for his clothes when he felt a stirring. "Shit," he muttered, as he felt his cock begin to expand.
Dan and Bill laughed. "Having fun, Evan?" Dan asked. Evan just watched as his cock got bigger, noticing that something felt different about it. As he stared, he saw it begin to change color, his head turning a dark brownish-black. As the color spread down his shaft his balls grew to enormous sizes, finally becoming as big as mangos. His genitalia now entirely brown, Evan watched as it began to grow longer and longer, ten inches, twelve inches, finally stopping when it got to about fifteen inches and as thick as a beer bottle.
He leapt from his seat in shock, then swayed as he felt the blood rush from his brain in order to fill his giant donkey cock. "I'll fucking get you for this, Mark," he growled.
Mark chortled. "Oh, I'm not done yet," he gloated, and, pointing at the other side of the room, he told Evan "I think you'll be wanting this."
Another flash, and a medium sized female donkey appeared in the room. Evan looked on skeptically. "I might have a donkey dick, but no way I'm...I'm..." He trailed off, and found himself unconsciously walking toward the ass. "What are you doing, Evan!" shouted Bill, half disgusted and half laughing. Evan approached the female donkey, and with a grimace on his face, grabbed its rear with both hands and began ferociously thrusting his penis, already dripping with animal precum, into the creature's vagina. Evan was horrified that he couldn't stop himself, but even more horrified that he was enjoying the experience. As his thrusts grew faster and harder, he began to shout with pleasure, his human grunting turning into loud brays, and his ears growing into hairy donkey ears. The guys all laughed at Mark's perverted act of revenge.
