As the cat jumped off the computer, Fang pulled away from Jeff's dad and began to change. His body shifted first, so there was the naked fur covered body of a man with a dog's head and a tail for almost a whole minute. Internal organs were shifting now, and soon a naked middle aged man was sitting on the floor wearing Fang's collar at the end of the leash Jeff's dad held.
"Jeff!" he shouted, then he shouted, "Tim!"
Jeff's younger brother dashed in, and stared at the naked man on the leash with dog shit on his dick.'
"What is it?" Tim asked, as he stared.
"Fang. The dog is useless, but now he's human?"
"Not useless. I tried to mount her, but can't see so well, no more, and can't smell that well either?"
"He doesn't look like much of a stud, bet he'd breed fine if we used Jeff's Chronivac to make him into a young stud," Tim blurted. "I bet Jeff changed him human. The Chronivac's supposed to be able to do that."
"Chroni-what?"
"Come with me and bring Fang and the bitch."
"Jeff? We're coming in!" Tim shouted throwing open the door to Jeff's room. The cat ran out.
"See here's the Chronovac. Jeff didn't think I knew he got it, but I pay attention. Look, it says here dog to human. Jeff must've done that and took off. But I can make Fang better."
Tim started typing.
Fang grew younger, taller, buffer, and handsomer.
Then the female dog grew into a naked, comely young woman.
"Now what?"
"Oh, I made Fang a sex magnet. He exudes hormones and his eyes have a hypnotic effect. His sperm are super potent too, and live twice as long as normal sperm, so he should get her pregnant. As soon as a sperm fuses with an ovum, he'll change back, and the dogs he impregnates will change back too. Now while they're going at it, let's go load up your truck with a bunch of bitches."
"What if they're not in heat?"
"The pheromones that Fang produces will instantly make any woman ovulate basically putting her in heat. So we'll have a room of horny naked women that we can use too."
"Hm? Your mother might object," Tim's father said.
"Yeah, but she doesn't like dog-breeding and she's spending the night at Gram's."
"Alright, you got me sold, but we're picking up condoms with the dogs. I don't want one of them getting pregnant off you, me or Jeff, and making some weird half dog-half human puppies."
"I don-"
"Where is Jeff? Jeff?"
"He probably thought you'd be mad, and took off. Bet he spends the night at his buddy Sam's."
"Right, his loss."
An hour later they returned with five young bitches. Within 20 minutes, Jeff's room was filled with six young naked women. Tim, his dad and Fang soon had mounted several of the women. Tim and his son were tuckered out, but Fang was going strong.
"You'd think that he'd have gotten them pregnant by now?" Tim's dad said waking up as daylight streamed in the open window. Fang was still going strong with one of the bitches. The other bitches were all sleeping too.
"Hm?" Tim grabbed his iPhone and asked Siri how long it takes to get pregnant. "Sperm can live up to a week in the uterus, on average it takes two to three days for a sperm to reach an ovum."
"Three days?" said Jeff and Tim's dad sitting upright, "How are we going to explain this to your mother? You need to change them back now, Tim! Call Jeff, get him over here to help."
Tim dialed Jeff. The phone in Jeff's jacket hanging on the back of the door started to ring.
"Idiot forgot his phone again. I'll check the manual."
