"How about some magic of your own? Nothing like mine, of course, but maybe the ability to make small changes in people and things?"
While the suggestion sounded like fun, I was worried about any potential cost. "I don't want to be a demon! And I don't want horns or a tail."
"Even though you find mine incredibly sexy?" Runt grinned and his tail looped around my leg.
I flushed as I proved his statement correct, my now impressive cock starting to come erect again. "Well, not yet, anyway. I want to stay human."
Runt chuckled. "As you wish. But as long as you stay as you are, does the prospect of having some magic interest you?"
He was tempting me, probably planning to lead me further down the demon path. Part of me was still scared to death of this strange being, but so far Runt had been terrific in every way. It was probably monumentally stupid to trust him, but I could not help it. I grinned up at him. "OK. That does sound like fun."
This time there was no doubt that he had done something. A powerful jolt made my entire body spasm and I gasped in surprise. It just lasted a moment, like a very strong electrical shock, and when it was over I felt fine.
Runt smiled. "Done. You can make small changes in appearance and age, even do a little animal magic. But anything you do will be noticeable - no reality changes."
I sat up and looked at my hands, and then down at my body. it was still strange to see the trim muscles and impressive sexual package, but I was more interested in testing out this new gift. "Let's go out!" I threw on some shorts and a T-shirt, and pulled on some sneakers. Runt followed me as we headed for the door, and just before I was going to say something about him still being naked, he was suddenly dressed almost identically.
We took the steps down to the ground floor and looked around. It was night, probably very early in the morning. I'd lost track of time with Runt and had forgotten to check before we left. I didn't even have my phone on me. Not many people were out this late, but I did spot someone I could experiment with.
