"It would be cool to be a lion or a stallion or something really spectacular like that," Jeff said, "but I guess you need a familiar that you can keep around the house."
Rais nodded. "Gotta be farily common. But there's lots of good pets."
Jeff shrugged, then grinned at his reflection in the mirror. It was so cool to be a kid again. "I know! How about a dog?" he ran some fingers through his mop of bright red hair. "An Irish Setter!"
Rais laughed. "Perfect! You'll still be a redhead, too!" He walked over and knelt next to Jeff. "I'll make the change slow, so you can enjoy it." He reached out and began to stroke Jeff's smooth, hairless chest. It began to push outward, and the skin began to sprout a very fine reddish fuzz that thickened rapidly. He slid his hand down Jeff's belly, leaving a trail of red fur that spread outward like fire across paper.
Jeff shivered, feeling a warm tingling that reached deep into his body. he could feel the muscles and bones under his skin shifting, yet it was not painful at all. Actually, he found the sensation really pleasant, and leaned into the gentle pressure of Rais' hand.
"Very good." Rais slid his hand down to Jeff's crotch. "Now for something you'll really enjoy." He cupped the prepubescent penis and barely visible testicles of Jeff's 12 year-old body, and began to massage them gently. His testicles swelled out first, the skin turning black as they grew to the size of walnuts. Then his penis turned slick and pink, the mushroom head fading into a pointed tip. A ring of black flsh pused up from the base of his penis and quickly swallowed the now fully-canine shaft, pulling it up against the red-furred belly.
Rais kept rubbing, slidingt he sheath back and forth. Jeff gasped as pleasure washed over him - his penis was rock hard and pushed far out from the sheath, larger than he ahd eve been as a human. Then a bulge appeared at the base. Rais slid his hand down to hold Jeff's penis tighlty around the knot, and the boy/dog shuddered and humped automatically as jets of watery precum shot out. Then a jet of thicker semen spurted out.
After the organsms stopped, Rais continued to massage the rest of Jeff's body. His arms and legs became very thin, then disappeared under a coat of thick read fur. By now, Jeff's entire body was that of an Irish Setter, with only his boy's head remaining human.
"Let's get you finished up, boy." Rais began stroking Jeff's head and cheeks. The child's lower face pushed out, his nose darkening and getting moist and his skull flattening.
Jeff felt strange now, thick-headed. Why couldn't he think right? Only then did he realize that As Rais made him a dog, his mind was also being altered! He tried to cry out, but it was already too late. The words emerged as a couple of short yips, and Rais just laughed as he made the final adjustments.
"There you go, boy!" Rais patted the young male Irish Setter on the head. "You'r a perfect specimen. I'm sure you will make a fine familiar. Bet I can get a lot breeding you, too."
Jeff whined and thumped his tail nervously. His Master was happy with him. Why did he have this feeling that something was wrong?
