It was just another summer day for Ben and his cousin along with their grandparents Max's old plumber friend Wes Green. From there that's when it all began, Ben began to crush on Wes's granddaughter Kai and it showed up. In a storm of purple lightning, the thing that would change everything appeared. A large wolf like creature appeared and stole a receiver from the village. At first Wes believed the beast to be some sort of Navajo werewolf called the Yenodoshi.

From there the quest to stop the beast began, eventually Ben would encounter the creature, he would engage with it in combat and would be bitten by the creature. If wasn't over then, it would soon be, Ben transformed back to normal and has his omnitrix would be scratched by the beast

After that, Ben would start his transformation from human to beast. Ben slowly transformed into a Yenodoshi, his human instincts clashed with his new animal like nature. Eventually it would be discovered that the Yenodoshi was actually an alien and not a mythical werewolf. Ben thought things would go back to the way they were after they stopped the alien werewolf but he was wrong, extremely wrong.

Ben did not transform back to his human form instead he ended up staying in the form of the werewolf. The omnitrix stayed on his wrist but he could not transform back, instead when Ben would transform into another alien they took on his wolf like features. Seeing that he would never look normal again, Ben had a fear of what others would do to him if they saw him.

Thankfully, Max had away of fixing that while they would try and find a more permanent solution to Ben's problem. Max gave Ben a gray mask that had the ability to hide and alter his appearance. It was known as an I.D mask and it would do the trick with keeping Ben's true appearance hidden from people. That was one problem solved now there was two other problems that would need solving.

The first one, how was Ben going to be able to transform back into a human and second, what was Ben going to say to his parents when he came back after summer was over. Max would have to help but he had faith that the problems would be solved. For now, Ben would have to try and continue on with his summer vacation, fighting aliens and all of that.

Besides transforming into a werewolf with a sonic howl, something else came out of the visit to New Mexico. Ben grew extremely close to Gwen, closer then they were before. Kai had wanted to make Ben be her dog in order for her to like him. Gwen was not having any of that, so she told Kai off in front of Ben, sticking up for him. From there Ben would protect Gwen and never leave her side.

At first that seemed harmless but the more Ben got closer and closer to Gwen the more that Max began to worry. Eventually it was revealed that Ben had imprinted on Gwen, meaning that she was his and he hers. That meant that Ben would not allow any other male who wasn't family approach her or he would go into a defensive attack mode. Max and Gwen tried to help Ben control this instinct by giving Gwen and Ben a unique drug that would dampen the instinct and mask Gwen at the same time.

For a time this method would work but as the two would get older the drug would start to work less and less. Then there was the fact that Gwen began to question her feelings towards Ben. She never thought she would enjoy someone protecting her and never leaving her side even if that person was her cousin and her cousin was a large wolf creature.

Besides the mental changes with Gwen, Ben was going through far more different changes. The older Ben got the more and more his human side began to vanish. If not for his friends and family, Ben would of become a savage monster. One of the instincts that Ben developed was a sort of mating instinct. Every spring Ben had the urge to mate and breed with his chosen female.

Unfortunately his chosen female was Gwen and Gwen knew this, Ben would do anything and everything to get to her and mate with her. Fortunately for Gwen, she had magic on her side and was able to hide her scent so Ben could not track her and find her. A side effect of not mating with Ben for so long began to effect Gwen's body. While Ben wanted to get to her, Gwen wanted to get to him.

The two were bonded and there was nothing that could be done about that. Eventually Gwen finally gave in and excepted her fate and her role.

It was one night during a summer night while Ben and Gwen were in high school. Kevin had gone off to spend some time with his girlfriend, leaving Ben and Gwen by themselves. Not knowing what to do, the two decided to go camping like they use to when they were younger.

"So, I've set up the tents and the rest of the campsite" Gwen said looking at everything

"I guess that means that I have to go and get the firewood" Ben said

"Yeah, better hurry before it gets dark out" Gwen replied

"How are we looking on food?" Ben asked

Gwen went over to the coolers and looked inside of them

"We're good on the snack foods and some dinner foods" Gwen answered

"How's the meat situation looking?" Ben asked with a tail wag

Gwen looked back in the coolers for a second

"We should be good for at least for a few days" Gwen answered

"So, I should maybe get us a bit more, just encase?" Ben asked

"Yeah, just encase, but nothing cute" Gwen answered lifting her finger up in the air

"But you think everything is cute" Ben said

"Fine, just get us some fish or a deer for all I care" Gwen said

"You can count on me" Ben said with a tail wag before he got down on all fours and ran into the woods

"I know I can" Gwen said to herself quietly

All by herself, Gwen walked over to her bag that was on the table, she opened it and took out multiple pill bottles

"Thank you grandpa" Gwen says to herself as she opens up the first pill bottle

These pills were the pills that her grandpa Max had given her to keep her safe from Ben's mating instincts along with keeping her bodily functions invisible to Ben's animalistic senses. Gwen had taken these pills many times before and they always worked until they didn't and she would need either a higher dosage or a new pill.

"Down the hatch" Gwen said as she swallowed the pill and washed it down with water

Gwen did this with the other pills till she was finished, now Gwen had to use her magic to finish off the rest of her daily regiment. Once finished with that, Gwen sat on a camping chair and looked up at the sky.

"I wonder when Ben is going to get back?" Gwen asked herself

With Ben

Running through the woods was Ben, he had just caught some fish for he and Gwen to eat. Right now he was tracking down a large deer for him to eat during the rest of their camping trip. A bonus of being an alien werewolf all the time meant that there was few times that Ben needed to go hero to do things that a normal person could. Like this, hunting a deer without a gun or anything else.

"That's it, don't move a muscle" Ben said to himself as he stalked the deer from the bushes

The deer was eating the grass unaware that Ben was about to strike at any moment. The wind was blowing down wind so Ben was hiding where the wind wouldn't give him away. As a twig snapped Ben rushed out of the bushes catching the deer off of its guard. In an instant Ben pounced on the deer before something else got his attention. Ben kept his claws around the deer's neck as he stuck his nose up into the air.

He sniffed the air twice before his ears caught the sound of something. They twitched twice before Ben realized what was going on.

"Gwen!!!" Ben said sensing that she was in serious danger

Ben got off the deer and let it go free, he turned in the direction Gwen was as the deer ran away

"Not gonna be fast enough" Ben said as he lifted up the omnitrix

In a flash of green light, Ben transformed into a sort of Kinceleran/Loboan hybrid

In an instant Ben zoomed off to go and save Gwen from whatever danger she was in

Time Skip

With Gwen

Gwen was in the middle of holding off a large bear that had wondered into the camp and began to attack her out of nowhere. Normally Gwen would be able to handle to bear with her mana and magic spells but when she would take those pills they would weaken her. Every time Gwen put up a barrier to protect herself the bear would slam into it and destroy it.

"Come on Smokey, stop putting up a fight" Gwen said to the bear as she rolled out of the way of its next attack

The bear lunged at Gwen and managed to grab on to her leg and shake her around a bit. Gwen yelled in pain as the bear sunk its teeth into her leg. The pain was unbearable for Gwen and she wouldn't be able to take much more of it.

"BEN HELP ME!!!" Gwen yelled at the top of her lungs

Suddenly out of the bushes came Ben in in his normal wolf form at full speed. He grabbed onto the bear and tossed it off of Gwen into a tree. Ben knelt down and saw that Ben was bleeding, he sniffed the wound then licked her face.

"Ben, BEHIND YOU!!!" Gwen yelled pointing at the bear coming straight for them

The bear dug its claws into Ben's back causing him to yipe from the pain before he grabbed the bear and threw it over his shoulder. Ben touched his back and saw that there was blood on his hand. That angered Ben and made him growl and snarl at the bear. Ben then charged at the bear as it got up and bit down into its neck. The bear roared from the pain and tried to shake Ben off of it.

Gwen watched on as Ben fought the bear off as best as he could, Ben used his claws and fangs and even tossed the bear around. Eventually Ben tripped the bear up, causing it to fall over on its back. Ben took that opportunity to jump on the bear and tear into its chest with his claws. Gwen couldn't watch anymore, she couldn't stand to see Ben kill the bear.

"Ben that is enough" Gwen said trying to get Ben's attention with no luck

"LET IT GO!!!" Gwen yelled finally getting Ben's attention

Ben looked over at Gwen who had tears in her eyes, seeing her upset, Ben slowly got up off of the bear and walked over to her. The bear got up and ran away as fast as it could. Ben kept his head down and walked over to Gwen without looking at her.

"Don't do that, you know I don't like it when you do that" Gwen said

Ben rubbed his head up against Gwen's side as he slowly licked Gwen's hand trying to make up to her

"Come on Ben, I need to bandage my leg and fix you up" Gwen said trying to push Ben off of her

Ben looked at Gwen's leg and saw that it was still bleeding, that gave Ben an idea. He activated the omnitrix and transformed into another alien. This time Ben transformed into a Thep Kufan/Loboan hybrid.

Ben extended his bandage like claws and the slowly extended and began to wrap around Gwen's wound on her leg. Once that was finished, Ben transformed back which revealed that his wounds had healed and now there were large scars. Gwen slowly got up and walked over to Ben, she ran her hands through his fur and saw all of the old scars that he got from protecting her. Seeing them, Gwen felt something deep down inside of her, it was something that she had felt before but always tried to hide or ignore.

This feeling had come up before in the past but she had always pushed it aside, this time was different for Gwen and she didn't know why. Maybe it was because Ben saved her again or maybe it was because she was finally starting to except her feelings.

"Ben" Gwen said as she put her hand under his muzzle

Ben looked at Gwen in the eyes and that was it, Gwen couldn't take it anymore

"I'm ready" Gwen said getting down on the ground before laying on her back

Ben instantly ripped off her clothes and licked her naked body before mounting her and gently biting down on her neck.

From that day on, Gwen would mate with Ben each time he was in heat, she finally could embrace the one she truly loved. The two kept this a secret and made sure no one would know what they would do when they were alone. Besides that, things continued on the same with them, Ben, Gwen and Kevin would save the day and hang out with one another. This would go on for some time as the trio grew older and older, eventually something would come up that would have to make Gwen decide where things would go from there.
