I don't own Yu-Gi-Oh! It is my understanding that when Joey got his own place, his sister moved in with him, so that is what I am using in this story which takes place after Dark Side of Dimensions.

Part One

Joey whirled around to see no one behind him. He sighed as he turned around to head for the park. His nose flared as he caught that scent again before looking over his shoulder; still no one there. And yet, I can smell him. He's there, but why he's following me I can't say for sure. My odd behavior the last couple of days could be the reason. I have a good reason to act this way. Serenity's turned fifteen and this is the first full moon since that important age.

Joey celebrated his sister's birthday like any other person but as the full moon drew closer, Joey started gathering supplies for an unusual dinner. He got a blanket, dog bowls, water, and raw steaks. His purchase of the bowls and steaks had caught the attention of Seto Kaiba as he too had been in the meat department. Joey was also aware that he had made canine sounds in Kaiba's presence but was sure he had been able to play them off as other sounds like making a bark sound like a cough, for example.

I try not to make those sounds, but it's not easy when the full moon is close. The last thing I need is for Kaiba to call me a dog again, considering that I'm actually a werewolf and that Serenity's a wifewolf.

We were born this way on our dad's side. The gene lies dormant until the first full moon after they turn fifteen. Dad, before he turned to drinking, told Serenity and me all about our heritage and we were both looking forward to unlocking it.

Well, Mom and Dad divorced and Serenity and I were separated long before I hit my fifteenth birthday. I went through my first full moon changes by myself as Dad would drink and pass out before moonrise. I found that I could talk and was in complete control of my actions. The only thing is that I have pointed ears during the cycle's daytime hours. Luckily, that's easy to hide.

When I got my own place, Serenity came to live with me and the timing couldn't have been better as she would soon unlock her wifewolf side. Tonight is that night and she's waiting in the place where I usually change. Now, I just need to get Kaiba off my tail, no pun intended.

Joey wended his way to a little known park entrance before stopping. "I know you're there, Kaiba so show yourself."

"All right, Wheeler," came Kaiba's voice behind him.

Joey turned to face Kaiba and he felt his heart beat faster. He had secretly loved Kaiba for quite a while but kept it to himself as he was sure no one would understand. "Why are you following me?" Joey demanded, switching mental tracks.

"You've been acting strangely and I want to know why."

"That's none of your business."

"Well, I'm making it my business." Kaiba noticed that Joey seemed restless as well as annoyed but to Kaiba, Joey's annoyed expression was attractive. He, unknown to all but Mokuba, was in love with Joey and was intrigued of what Joey was up to this night. "Why are you coming here instead of home?" Kaiba asked, indicating their location.

"Serenity and I are camping out." Joey was being truthful; he just wasn't saying that they were going to be wolves.

"Indeed." Kaiba saw that Joey was trembling a little. He raised an eyebrow. "Are you all right?"

"Fine," Joey said curtly and turned to walk away.

But Kaiba was too fast and he seized Joey's arm. "You don't look fine. You're shaking and now sweating. Your skin also feels warm."

"That's true, but really I'm fine. Now, let go." The blonde yanked his arm free.

"I disagree. You seem ill."

Joey sighed, knowing Kaiba would not leave until he proved he wasn't sick; furthermore his coming transformation prevented him from moving. "I look sick but they are common symptoms of a condition I've had for three years."

"What…condition?" Kaiba asked, concerned that he had contracted it when he grabbed Joey's arm.

Joey responded by giving a howl and then a low growl as he instantly shifted into a strong large gold wolf. The low growl was to express the annoyance of having to change in front of Kaiba despite his feelings for him.

Kaiba stared at Joey in surprise. He's a…werewolf? Heh, well that explains why he reacted so strongly to my dog remarks. A smirk crossed Kaiba's face before he laughed a little. "I always thought you were a dog, Wheeler, and here's the proof."

"I'm not a dog," Joey bristled. "I'm a werewolf. I was born one and fifteen is when it activates but the change comes with the first full moon after their birthday."

Kaiba's smirk didn't waver. "I guess that makes you a mutt."

"Werewolf," Joey countered.

"Right. Half-human, half-wolf. That's what one calls a half-breed or a mutt. Your fur also gives you the look of a dog. A weredog." Kaiba began to laugh hard, saying, "Weredog," in between laughs.

Joey felt his temper boil up, knew what it meant, and did not fight it. "I'm not a dog, damn it!" he howled before sinking his teeth into Kaiba's hand.

The brunette cried out before grabbing his hand once Joey had released it and glared at Joey. "You bit me!" He then breathed in realization and said in soft shock, "Oh, God. You bit me. I'm going to become a werewolf."

"Yeah. Tomorrow night," Joey growled. "And it kind of serves you right for mocking me."

"Wheeler, I want you in my office tomorrow to explain everything," Kaiba snapped before leaving.

"I'll be there," he called back. And I will explain everything, he added silently as Kaiba left. That includes the fact that I love you.

A loud, lonely feminine howl sounded and Joey immediately took off toward it. He gave a howl of his own to say he was coming. He emerged into his usual changing place to see an auburn-furred wolf with green eyes. She went up to him and rubbed a cheek against one of his own. "Joey, I was getting scared," she said.

"I'm sorry, sis. Kaiba held me up."

"He did?" Serenity laid down and seized a steak. "How come?"

Joey followed Serenity's action and chewed brutally on his steak before saying, "He noticed my odd behavior leading up to tonight. He followed me and noticed when I started sweating and shaking. I ended up changing in front of him.

"He started mocking me calling me a dog, a mutt, and a weredog. I got angry at his words and…"

"You bit him," Serenity cut in, not angry that her brother bit someone; she probably would have done the same. "He'll show the signs of a werewolf as well as the feelings and desires of one tomorrow before moonrise."

"Yeah and he demanded I come to his office tomorrow to explain everything. I intend to include something I never told anyone."

"What?"

"I love him."

"Joey, that's wonderful." Serenity leaped at Joey and the two tumbled over each other, yipping and laughing in joy as they played as brother and sister wolves would.
