Magnus pulled a wand out of his cloak and pointed it at James. James crumpled to the floor over as an invisible wave of energy hit him. He got back up on one knee, winced, and stood up straight, feeling a little dizzy. James felt a very weird and very wrong sensation in his nether regions. It felt like some part of him was going numb or shrinking. In the end, he could feel that something that should be part of him was gone. Looking down, he noticed that his penis was smaller and that the balls underneath it were ... not underneath it anymore!
"Where are my ... I mean, what happened to ... um, what did you ... ?!"
James couldn't even complete a sentence he was in such shock. Then he felt something moving through his tiny penis, and before he knew it, a bunch of yellow liquid was spilling out onto the floor beneath him. The wizard smirked. The witches grimaced.
"Oh, Magnus, that's really not fair," said Hilda. Magnus burst out laughing.
"What can I say?" said Magnus. "Even unmagicked pet owners know they're supposed to spay and neuter. And I wouldn't want you to miss out on housebreaking your new companion. In the meantime, I imagine you'll just have to start cleaning up after him, unless you can find some OTHER means to prevent messes."
James blushed red and covered his face as his trickle came to an end. Magnus swaggered toward the dining room.
"Well now, ladies, what's for dinner? I suppose James can join us. I thought we might light the candles tonight, if it's all the same to you."
Matilda shook her head at the others and followed Magnus. Hilda patted James on the back and summoned her magic mop, which floated in and cleaned up his urine by itself. Gilda rolled her eyes and snapped her fingers, and then a diaper appeared on James's privates. Reluctantly, he followed the witches toward the dinner table, wondering what else could possibly go wrong for him.
