After getting home, Nate and Kris reassured their worried mother that they were okay. In the weeks that followed, Kris found that his latent lycanthropy and older body had a subtle effect at his school.
Formerly an ignored kid, he was now popular. He even made the basketball team, despite being hopeless in earlier tryouts. In the showers he noticed that sis arms and legs were hairier than anyone else's. And though some of his classmates made a habit of shaving their groins, he was proud of his thick bush and wore it with pride, especially since it hardly concealed his cock, which was the biggest in the lockerroom. He could feel the effect of his new sexual charisma on his teammates.
The girls felt it too. Emily, the prettiest girl in period 3, actually spoke to him. It helped that her brother Josh, captain of the basketball team, had a secret crush on Kris and talked about him endlessly to his sister. So it happened that one day Emily asked Kris if he'd like to go over to their house to study for the upcoming history exam. Kris was conflicted. The full moon was that night, and he couldn't take any chances, especially with his first full transformation. On the other hand Emily was super-hot (and so was her brother), and he couldn't pass up a chance like this. He accepted.
As Kris entered Emily's house, his attention was immediately grabbed by their dog, an enormous mastiff bitch. "That's Minnie," said Emily. "If she acts a little weird, it's because she's in heat." Kris nodded, his nose taking in the bitch's scent and causing his penis to start hardeningt. "Uhh, let's sit down" he mumbled. They found a room on the other side of the house and began studying. But every so often Kris caught a whiff of Minnie's scent. He could hear the bitch whining for him too. Any thought of Emily's charms evaporated as he thought of the mastiff and her dripping, needy cunt. It was taking all his willpower to sit and study. Sooner or later the bitch would drive him out of control.
Fuck, he thought, I have to leave. It'll be dark soon and I have to rush home before the transformation.
He closed his textbook and positioned it to block his bulging groin from sight.
"Sorry Emily, I have to go."
"Ohh," she sighed, "but my Mom's making dinner! Just stay another half hour."
"No, really, I have to go."
"Well, would you like some food to take with you? Mom should be finished cooking right about now."
"Sure, sure, but I have to get going."
Josh now spoke up, a bulge visible in his own jeans. "Can I walk home with you Kris?"
"Err, I think I need to be by myself..."
"Mom!" cried Emily, "can you put some lasagna in tupperware for Kris?"
"Sure thing honey, just come down to the kitchen when you're ready!"
Kris swallowed. He needed to relieve himself of this erection.
"I have to go to the bathroom--I'll meet you guys downstairs."
As soon as Emily and Josh had left the room, Kris ran to the door and flung it open to discover Minnie, waiting for him. The dog corralled him into the room, knocking him over, and put her nose to his groin. She began whining. Kris was now going out of his mind. As if guided by an invisible hand, he put his nose to Minnie's rear and sniffed. Then he started licking. "AggrrgggFuck it!" he cried, slipping off his shirt and yanking down his jeans to free his reddening dick. He slowly guided it into the bitch's cunt and began to fuck doggy style, relishing how Minnie's back fur rubbed on his bare chest with every thrust he made. Most incredible of all, he could feel the base of his dick swell into a ball and lodge itself within Minnie. It was all so mindblowing that he didn't hear footsteps on the stairs and approaching voices.
"You didn't come down, so we just wanted to see if you were--" Emily's Mom stared she beheld Kris fucking their family dog. Emily and Josh were behind her and looked on with dumb astonishment, mouths gaping, goggle-eyed.
Kris finally saw them, and momentarily came to his senses.
"It's not what it looks like..." he said, in a very small voice.
Emily blinked and pointed at Kris. "You, y-y-you're growing hair!"
Sure enough, little hairs were sprouting all over Kris's body.
The full moon had risen.
