Brian went to his room, and locked the door. His first adventure had already taken a bizarre twist, and he was looking forward to a good night's sleep.
He undressed, peeling off the stablehand clothes that he magically acquired when the wizard transformed him. Looking in the cheap mirror on the wall, he studied his new body. His head and face were the same, but everything else seemed to have changed. His body was stronger and bulkier, and perhaps slightly taller as well. And of course, his new cock and balls were huge beyond belief - that stableboy had been at the extreme end of the human bell curve, when it came to genitalia. He reached down, and stroked the length of his impressive member, marveling at its impressive size.
"I'm glad to see you like it."
Brian whirled around, and saw the wizard from earlier, grinning lustfully and lounging on his bed.
"What do you want?" Brian snapped.
"That big cock, of course," laughed the wizard, "I know you know. I made sure you got plenty of memories with it."
Brian reddened slightly. He remembered sweat-drenched nights of plowing the wizard with his mighty cock. Those were the stablehand's memories, of course, but they seemed real to him. His dick rose, protruding proudly from his body.
"I can see that you do remember," the wizard smirked. He wiggled his finger in an elaborate gesture. "Get over here, stud."
Brian lurched towards the bed, unable to resist, despite his advanced elven mind. He watched in strangely familiar awe as the wizard’s clothes seemed to melt away, revealing a thin but well-toned body. Brian got on the bed, and crawled toward his master, his huge cock begging for action. The wizard lifted his legs, exposing his ass. Without hesitation, Brian plunged in, driving his donkey dick up the wizard’s hole with practiced ease. Although a small part of Brian’s mind was horrified by what was happening, he could not stop. Instead, he began to pump himself further and further into the wizard, bucking and grunting happily, while the wizard pulled him ever closer.
"I think you just might do," whispered the wizard with a smile.
