Stacy gave Jeff a puzzled look before turning to open the front door.
There, standing stark naked, was a young man, perhaps 19 or 20 years old. He was, to Jeff's delight and dismay, very handsome. He stood there, about 5'10", looking somewhat confused. His toned body flexed, as if he was testing out these muscles for the first time.
"I'm Max. I was outside chasing the cat when I this happened. What happened? Stacy, am I a boy? I still feel like me, but I feel like a human too. What happened?" Although Max said this in a straight forward manner, his confusion and anxiety were evident in his eyes and tone.
Stacy took a deep breath (she couldn't help but notice how hot he was), "We changed you and...I guess our brother, who was a dog, but I guess...well, it's a long story I think" she looked momentarily confused,"but you are Max."
Jeff couldn't help by get aroused by this naked male. Horrified, he felt his body responding. His nipples were hard, and his vagina was getting moist! The alien sensations were unlike anything Jeff felt as a guy. Embarrassed, he glanced at his brother Chis. He caught Chris looking at him. Chris quickly looked away. That little perv! He was going to get pounded once he got back to his real self.
Max finally noticed Jeff, who was trying to be as inconspicuous as a beautiful, naked woman could be. "Well, hi." Jeff saw Max's cock begin to get hard and rise. He heard Chris snicker and Stacy gaspe. Jeff licked his lips and tried not to be noticed noticing it.
