Hi all, Ashley here. Long-time lurker, first-time published. This fiction is set in an alternate future within my own fanon. As such, some elements of this story do not follow the canon story line. Ben 10, its franchise, and characters are the combined property of Man of Action and Cartoon Network. Some of the characters do not have first names or last names in the show, so I took the liberty to provide them with some for the sake of story flow. This story also contain several OCs, all of whom belong to me. Any similarities with other fan fiction on this website or others is unintentional, although I have to say I am quite inspired by the works of RenkonNairu and The Otaku with Hazel Eyes (kudos for excellent writing, good grammar, and having the characters stay in character!). Lastly, this story contains explicit language, graphic sex, and violent themes. If you are under 18 or do not consider yourself a mature audience, please press the "back" button and choose a different story. Thanks.

With that being said, I hope you enjoy my work.

Chapter 1

The Wedding

"This is getting really old!" Gwendolyn Tennyson shouted, as she soared through the air, placing one mana barrier after another in front of the rampant part-octopus-part-crab creature that had been wreaking havoc through the city. The creature didn't seem particularly sentient, guided mostly by fear and a fight-or-flight response, but it had an overwhelming amount of power and it had no intention to stop anytime soon. Gwendolyn never liked using her powers for brute force, but after countless unsuccessful attempts to rein in the creature, and the ever-increasing trail of destruction it had left behind, she was changing her mind about it. "Kevin, stand back!" She ordered at the pale, long-haired man on the ground, running alongside the creature.

Kevin Levin grumbled to himself, but obeyed. The creature had paid less attention to his punches than he would have mosquito bites; it almost broke his heart. He watched Gwendolyn's figure lit up in a magenta glow, a few shades darker than the mana—life energy—she exuded. The glow transferred from her body toward the creature, trapping it in its spot and drawing enough of the creature's own mana to knock it out cold. As the now-unconscious creature flipped onto its back, Gwendolyn dropped herself next to Kevin and gave him a nod.

He whipped out his badge-slash-communicator and spoke into it. "Agents Levin and Tennyson reporting to officers on duty, unknown creature wreaking havoc in downtown Bellwood has been subdued and ready for transport," He gave their coordinates and ended communication. Glancing at the large digital time display on one of the building nearby, he winced. "We are so late for our own wedding."

Gwendolyn sighed. "I should have listened to you, civil registration at the town hall would have been so much easier."

"Now I know we're in trouble. You're actually agreeing with me." He smiled and took her hand. They were meant to be walking down the aisle in less than twenty minutes. "Come on, better get going."

As if on cue, two large futuristic motorcycles, one green and one red, skidded to a stop in front of them. The rider on the red bike lifted her visor, revealing a pair of chocolate-brown eyes. "Hop on, you two. Aunt Natalie is going berserk." Kai Green commanded. She dug a spare helmet from the storage under the backseat and tossed it at Gwendolyn.

Gwendolyn let out a grateful sigh and hopped on to the red bike, wrapping her arms around the Navajo girl's waist. Likewise, Kevin hopped on to the back of the green bike—Ben Tennyson's—spare helmet be damned. They sped off into a time-space loop and arrived at the lakeside mansion Gwendolyn's parents had hired for the event in thirty seconds, instead of thirty minutes as it normally would. The beauty of alien technology!

Natalie, Gwendolyn's mother, was standing at the entrance, dressed to the nines in a formal dark blue dress, clutching at her pearls with worry. She nearly fainted at the sight of her daughter, the bride-to-be, in her disheveled post-combat form. "Where have you been?" She shrieked. "Look at you! We have less than fifteen minutes! Oh—"

"Don't worry, Lili, we'll take care of them." Max Tennyson suddenly appeared, looking quite dapper in a sleek grey suit that matched his eyes. He placed his robotic arm on Kevin's shoulder, unceremoniously dragging the twenty-six-year-old man toward the locker room by the pool, designated as the groom's dressing room for the day, with Ben trailing behind them. Kai grinned at her fiancé's aunt and headed into the mansion with Gwendolyn in tow.

"Thank you," Gwendolyn gave Kai a sincere smile as they raced up the stairs, toward the suite reserved as the bridal quarters.

"No problem," Kai replied. "Now you better do me some favors on my wedding day." She grinned.

Gwendolyn chuckled. "You know I would anyway!" The girls had not get along well the first time they met—they each thought the other was full of herself, and each disliked the other's influence on Ben. However, the three had once again crossed paths when they discovered that Kai was also a student at the college Gwendolyn attended. Their maturity had guided them toward a mutual understanding, and so their friendship bloomed. Not without its challenges, for both women were stubborn, strong, and had their own little rivalries when it came to both academic excellence and heroic deeds, but they knew they could trust each other.

The women's smiles faltered as soon as they entered the suite. Pairs of hands and choruses of high-pitched voices attacked the two, shoving and prodding them—especially Gwendolyn—in various directions.

"Where have you been?"

"Late for your own wedding, imagine that!"

"Your mom's driving everyone crazy!"

"Anyone who's not a bridesmaid, get the hell out!" Kai yelled. The room came to a halt, and several females she did not recognize, presumably from Gwendolyn's mother's side of the family, slowly backed toward the door and exited. That left herself, Emily Youngberg, Gwendolyn's best friend since childhood, Julie Yamamoto, with whom the gang was still friends after she went on to become a professional tennis player and got a new boyfriend, and Lucy Mann, Gwendolyn's Lenopan cousin-in-law (Lucy's aunt married Ben and Gwendolyn's uncle).

Gwendolyn held her hands up. With a flash of pink, she was transformed. The messy ponytail she had been sporting was now clean and hanging down below her shoulders in soft curls. The sweat, grime, and blood that decorated her skin was gone, replaced by a sweet-smelling scent. Her clothes were now also clean and neatly folded on the bed, leaving her naked. "Where's my dress?" She asked. With the amount of time they had spent at the tailor's studio getting their dresses fitted, the girls were no longer shy about being nude around each other.

"Here," Julie held it up to her. As soon as Gwendolyn slinked herself into the white mermaid dress, Julie sat her down and began working on her makeup, while Emily came at her with a curling iron. In the meantime, Lucy helped Kai into her bridesmaid's dress, a knee-length pouf dress just like the one she had on, but in a different shade. To compliment the lilacs and the yellow roses Gwendolyn had picked out for decoration, each girl got to wear a unique shade of purple—Emily's was a pale lavender, Julie's was a sweet mauve, Lucy's was electric violet, and Kai's was a deep violet—while carrying a bouquet of yellow roses, which turned out to be rather cute. It could have been much worse.

"Lucy, would you mind checking up on the boys?" Gwendolyn asked, face contorted as Julie applied mascara to her lashes.

"Sure thing, Cuz!" Lucy replied, cheerfully, and bounced her way out of the room.

Gwen exhaled, looking at her reflection in the mirror. Oh, what a day. Gwendolyn had never imagined that this was how it would have gone; sure, she dreamed of weddings and dresses and flowers as a little girl, but those dreams had slowly disappeared as she grew up. She and Kevin had been in a relationship for a good chunk of the last ten years, minus the several months he had spent as Ultimate Kevin—the second time he absorbed Ben's Omnitrix, when he was seventeen. They had moved in together during Gwendolyn's second year at college, much to her mother's dismay. Originally, they were living separately—Gwendolyn stayed at the dorms while Kevin rented the small apartment on top of the garage where he found work. There were mentions of marriage and kids, occasionally, but they were mostly done in jest. They didn't need to utter vows in a roomful of people to prove their commitment to one another, or to sign some papers. It wasn't until Natalie invited the two out for dinner on the eve of Gwendolyn's twenty-fourth birthday and essentially threatened Kevin to either propose, or the two would one day walk into their own surprise wedding, that it became a real possibility.

And today, that possibility was becoming a reality.

Gwendolyn wasn't unhappy, of course. On the contrary, she was a little giddy about the whole thing. As much as she hated to admit it, she was quite a romantic. Gwendolyn Catherine Tennyson, soon to be Gwendolyn Catherine Tennyson-Levin, finally a bride!

"Thanks Julie, my makeup looks amazing," She said, admiring the half-Japanese girl's handiwork. Julie beamed proudly at her comment. "And thanks to you, too, Emily, I would have burned my ear off or something if I tried to do that myself."

Emily giggled. "You're way too modest, but I'll accept the compliment." She ran her fingers gently through Gwendolyn's flaming red hair. "Just one last bit and we're good to go."

"I'll get your shoes on," Kai chimed in, fetching the pair of pearly-white pumps from its box and fitting them onto Gwendolyn's feet.

"Gwenny! Aunt Natalie wants to know how much longer you need, because apparently, you're already two minutes behind schedule!" Lucy's blonde head poked out of the doorway, her singsong voice barely masking her frustrations.

"Coming!" Gwendolyn replied, placing the lilac wreath carefully on top of her head before standing up and marching out the door as gracefully as she could manage, followed by the other girls. Collectively, but silently, they thanked the owner of the mansion for installing an elevator, because as romantic as descending a spiral staircase in one's wedding gown may sound, it was rather impractical.

The elevator took her directly to the grand ballroom, where both the ceremony and the reception was to be held. "Oh, Sweetie, you look fantastic." Her mother had been waiting by the elevator with her bouquet. She handed it to Gwen and pulled up the bridesmaids to line up next to the altar. At Gwen's insistence that "having a male family member 'give away' the bride to the groom is anti-feminist," it became Emily's job to trail by Gwen's side on her motorized wheelchair as they walked down the aisle.

It felt like it was a thousand miles long. When she arrived in front of the officiator - none other than her own Grandpa Max - it felt like a whole lifetime was over. She had fought battles in front of international camera crews and given speeches in front of galactic leaders, but she felt all the eyes in the room on her and she couldn't help but feel a little nervous. Kevin was visibly nervous, too—standing frozen by her grandfather, obsidian eyes fixated on her figure. He looked irresistibly handsome in a black tuxedo, his long jet-black hair tied back in a sleek ponytail. She flashed a smile at him and he grimaced in return. Her cousin, standing a few feet behind Kevin, caught this exchange and gave a mischievous grin. Gwendolyn decided to ignore him.

Grandpa Max began his speech. It was nondenominational, direct, and concise - something her mother would no doubt bring up with her later—but it did the job. They exchanged rings and "I dos" and kissed. They didn't prepare for custom vows—didn't feel the need to exchange empty words over a lifetime of action. The crowd cheered, the song played, and they headed out to the floor for their dance. He was a little tense, but he was doing well otherwise.

"Relax," She whispered. "It's done. We're married."

Kevin looked as if somebody had slapped him. "Did I—did I do alright? Did I say anything wrong?"

"You did great, Kevin. Plus, nobody cares about the groom—weddings are all about the bride." Gwendolyn snickered. "I love you."

"I… love you too." He was suddenly awestruck by how beautiful she was. She had always been pretty; it was hard not to notice that about Gwendolyn, even when they were just kids. There was something about the lighting that made her green eyes sparkle more than usual, and whatever that shade of lipstick was called, it made him want to give her an obscenely intimate kiss right there, in front of all the guests.

The song changed and Kevin felt a tap on his shoulder. "Mind if I cut in?" Ben asked, the same mischievous grin as the one Gwendolyn saw before plastered over his face.

"Actually, yeah, kinda, but go ahead." Kevin grinned back and turned around, only to bump into Kai, who offered him a hand. He wasn't used to dancing with anyone else, but he supposed he'd try. Kai grimaced when he stepped on her foot within

"Congratulations, Cuz." Ben took Gwendolyn's hand and twirled her around as the speakers blared a song with a slightly faster tempo than the previous one.

"Thanks," She replied. "You're next. Could you believe it? We're grown-ups! Isn't that terrifying?"

"To be honest, I was kind of expecting this a little sooner from you." He chuckled. "You've always been the mature one."

"You're catching up, sort of." Gwendolyn noticed the lack of brown stubble that had been peppering his face in about the past year or so. Ben had been trying and failing to grow out his beard, and tonight it seemed that he had decided to shave himself clean for the event. "Are you excited for your wedding? Lots of important people are going to be there." Ben and Kai's union were going to be held in outer space, attended by none other than the Magistrata herself, among many other world leaders and celebrities, and broadcast to the entire universe.

Ben shrugged. "Sure am," He replied, unconvincingly. "You've got some pretty cool guests, too."

Her eyes swept around the room and she couldn't help but feel rather proud of herself and her cousin; the room was filled with familiar faces, individuals of all shapes and sizes (much to her mother's delight) they had encountered throughout their years of delving into intergalactic business. Some they had known since they were children, like Eddie Grandsmith and Cooper Daniels. Some they encountered a while later, like Alan Albright, Helen Wheels, and Manny Armstrong. There were friends of hers and Ben's from school, including former bullies Cash Murray and J.T. Baker. A number of their colleagues were there as well, including Molly Gunther, Elliot Robinson, and Ben's Revonnahgander partner, Rook Blonko, along with his own betrothed Rayona. And then there were Kevin's—ahem—friends, like Argit, the porcupine-like alien, who at least had the decency to dress up and act… well… decent. She watched as he made small talks with her grandmother, Verdona, who seemed rather amused by the creature.

Wait—"Grandma?!" She gasped and stopped in her tracks, nearly causing Ben to stumble over her feet. She let go of his hand and began to make her way to her estranged grandmother, but Grandpa Max had gotten to her first. The two headed out to the floor to dance—Verdona's favorite human pastime, as she had once told her. A strange knot swelled in her stomach as she watched her grandparents embracing one another, swaying to the music. Falling in love outside your own species is difficult, and not necessarily from a reproductive point of view. Max and Verdona had crossed paths as young adults, but the differing lifespans of the two species meant that while Max had developed into a fully mature human over the years of their marriage, Verdona was only just hitting adulthood by Anodite standard. As much as she might have loved Max, and Gwendolyn really believed that she did, she could not have stayed and survived. She was a free spirit, born and grew up in a world without a care. Staying on earth, with its rules and conventions, traditions and expectations, would dim the light that was Verdona, and Gwen believed that Max knew it, too. That, she figured, was the main difference between her and her grandmother, the reason why she had rejected Verdona's offer to live in Anodyne many moons ago.

So, she brought her thoughts back down to earth, fulfilled her duty and danced with one guest after another, and fantasized about what she and Kevin were going to do once they were free of all this. She ate the silky vanilla wedding cake (vegan, gluten-free, and nut-free, upon request by Aunt Sandra!), sipped on her champagne after each toast (downed a whole glass after a particularly embarrassing speech from Lucy), and handed out favors to the guests that were leaving early. When finally, the only people left in the ballroom were the ones also staying at the mansion, Gwendolyn grabbed Kevin by the hand and led him outside. She wrapped her arms around the back of his neck and pressed her lips against his, pulling him as close as their situation permitted. As their tongues began to dance, she wanted him to rip her dress open, wanted him to make her scream, wanted to not care about anything else in the world. Between wedding planning, work, and her doctorate thesis, the last few months had not been kind on their intimacy.

"Ahem," they broke apart when they heard a cough. Gwen's older brother, Ken, was standing nearby. "Mom just wanted me to tell you and Kevin that you guys can go up to your room if you want, and not to worry. She's going to take care of the clean-up." He grinned. "If I were you, I'd disappear before she changes her mind." With that, he retreated back inside.

Gwendolyn and Kevin exchanged a look. Without a warning, she used her powers to teleport them into their suite.

"Ugh!" Gwen kicked off her white pumps across the room. Despite all of the spells she used to make her shoes comfortable, her feet were blistered and sore. And, ew, stinky. She went into the bathroom and began filling up the tub with hot water as Kevin took off his many layers of clothing. He was not in half as much pain as his new bride, but he was equally exhausted. He entered just in time to see Gwendolyn shrugging her dress off her bare hips.

"Why didn't you tell me you were commando?" He hissed, his foot caught in the pipe of his pants as he attempted to take them off as quickly as possible.

"Because, I don't know, I expected you to grope me at some point and figure it out yourself." She smirked, and lowered herself into the tub. "Now, get in."

He didn't need to be told twice. He slipped in across from her and pulled her forward until she was straddling his lap. He made a trail of kisses down her neck before suckling on the patch of skin just below her collarbone, his hands roaming her body. She squirmed against him, feeling his erection grew underneath her. His hands kneaded her perky breasts as she ran her own hands through his thick black hair. He loved the sound of her moans. One of her hands wandered down, grasping his hardness and made soft pumping motions until he came to full erection. He groaned and gripped her ass, fingers teasing the edge of her folds. He felt warm slickness there that had nothing to do with the water. She kissed him full on the lips, positioning herself carefully so that her entrance met the tip of his penis, and plunged herself down. His nails dug into her flesh and she moaned into his mouth.

He started slow, purposeful, enjoying the feeling of her muscles stretching and clenching around his member. She was good at that. He felt a sharp tug at his hair and picked up his pace, pumping in and out as fast as he could, given the circumstances. He latched his lips onto her nipples, sucking and softly biting each of them. Their moans and grunts echoed against the bathroom walls. It took all his might to keep from ejaculating too early, wanting to let her get to her climax first, and once she did he felt himself let go as well.

They were tired and pent-up. Kevin wanted to fall asleep right then, but Gwen nudged him as she unblocked the drain. "Come on, the bed will be so much more comfortable than this tub." She hopped out and wrapped a fluffy white towel around her body before handing Kevin the other one.

"Mmm, 'kay," Kevin grunted, taking the towel off her hand, quickly dried his body, and threw himself on top of the bed covers, stark naked. Gwendolyn sighed, drying herself a bit more thoroughly before slipping next to him.
