Fun While Grandpa's Gone.

"Ben! Did you drink my herbal water?!" yelled Gwen as she shut the refrigerator door.
"Uhmm... what?" said Ben, sitting at the kitchen table and drinking from a fancy bottle of water while playing a webgame on Gwen's laptop.
"The one with 'Gwen's Herbal Water, Do Not Drink' written on the label!" replied Gwen, now searching in the Rust Bucket's cabinets. Ben looked at his fancy bottle of water. There was something written on the label in permanent ink. 'Gwen's Herbal Water, Do Not Drink.'
"Huh. I wonder why I didn't notice that," mused Ben as he lifted the bottle to his lips and took another swig out of it.
"BEN TENNYSON!" screamed Gwen as she rushed to the table and snatched the bottle out of his hand. "...You asshole! It's empty!" she exclaimed as she held the now-empty bottle up to her eyes and shook it.
"What's the big deal?" groused Ben, putting his attention back to the webgame on Gwen's laptop. "It didn't even taste all that good."
"Then why did you drink it all?! Ugh, Ben you're impossible!" shouted Gwen as she tossed the empty bottle into the kitchen's trash cash. After that, she rushed back to the table. "And quit using my computer!" she said, snatching it off the table and folding it shut.
"Hey! Give that back!" demanded Ben as he tried to wrestle the laptop away from Gwen. "I have to finish that level or the anime girl won't show me her tits!"
"You've been using my laptop to look at porn?!" shouted Gwen.
"What's the big deal? You do too!" replied Ben, causing Gwen to blush red. "I've seen some of the folders you have on there! It's full of kinky videos and comics. Plus, you've got drawn porn by like, five different artists; that moose guy, that crusher chick, that flopping guy, and a bunch by some guy called sire!"
"Why were you even looking at that!?" Gwen shouted, her eyes full of fire. Ben opened his mouth to defend himself, but Gwen quickly cut him off. "Never mind, I don't care! I'm sick and tired of you getting into my personal stuff, and I'm going to do something about it!" Gwen stepped away from Ben and slid her computer on top of the refrigerator before turning back to him and pointing at his face. "I challenge you!" exclaimed Gwen. Ben furrowed his brow at her.
"...You can't be serious," he said. "Challenge me at what?"
"To a fight, dumbass!" Gwen shot back at him.
"Uh, Gwen? I'm a hero, remember? I'll beat you in like, two seconds," scoffed Ben. Gwen withdrew her finger and placed her hands on her hips.
"Oh? If you're so cocky, how about we make things interesting?" said Gwen, quickly forming a plan.
"Interesting, huh? You want to make a bet or something?" replied Ben.
"Exactly," replied Gwen. "If I beat you, you have to do whatever I say for a whole day."
"Alright, and if I beat you, you have to do the same," said Ben, grinning at the thought of Gwen being forced to do all his chores for a day.
"Deal?" asked Gwen, extending her hand.
"Deal!" replied Ben, shaking hands with her.
"Good. Let's take it outside," said Gwen, pulling her hand away from Ben's and walking out of the Rust Bucket's side door. The sun was shining brightly overhead. The Rust Bucket was parked in the corner of a small clearing in a dense, Virginia forest. Grandpa Max had brought them all here to look for lost treasure from the Civil War. Unfortunately, Grandpa had been gone since the last afternoon, leaving Gwen and Ben to annoy each other in the safety of the Rust Bucket. The forest was too dense to drive through, causing Grandpa to disembark on foot while the kids stayed behind and held down the fort. Too much exposition makes Jack a dull boy, Grandpa is gone, Ben and Gwen can do whatever they want.

Gwen stood in the clearing and struck a fighting stance. Ben walked out of the Rust Bucket and casually strode over to her.
"Alright Gwen, are you ready for this?" exclaimed Ben as he displayed his hands in a "sho-nuff" motion.
"Bring it on, Twerp," said Gwen coolly.
"Alright, it's hero ti-" shouted Ben before being cut off as a rock flew into his head. "OW!" yelled Ben as he clutched at his throbbing forehead. "No fair Gwen! That's cheating!" he exclaimed. He opened his eyes and blinked back a couple tears. "Huh?" he looked around. He couldn't see Gwen anywhere. "Hey, doofus. Where'd you-" he tried to say before feeling a pair of arms wrap around his chest from behind.
"POWER SUPLEX!" roared Gwen as she pulled backwards, rocketing Ben off the ground. Gwen pulled back on her left leg and twisted her body as she spun Ben and then slammed him down into the dirt at full force. Gwen then dove onto his body and pinned him to the ground.
"1....2.....3.....4.....5....6....7....8....9....10!" she counted. "You're out!" She yelled proudly as she stood over Ben, striking a victory pose.
"Oww..." Ben mumbled feebly. Gwen reached down and grabbed the back of Ben's shirt and hoisted him onto his feet, and then dusted him off.
"You're fine, dweeb. I didn't throw you down that hard," said Gwen, grinning with pride because of her martial artistry.
"I'm fine," said Ben, swatting away Gwen's hands. "Anyway, it didn't count! You cheated!"
"Cheated? Pfft, as if. I beat you fair and square," replied Gwen. She raised an eyebrow at Ben. "Or would you rather have a rematch?" she asked, holding a fist to Ben's face. Ben eyed her fist angrily for a few moments, and then sighed and threw his hands in the air dejectedly.
"Fine, you win! Whatever,"
"I'm so glad you agree Ben!" squealed Gwen as she gave her cousin a quick hug. "Now then, what were the terms of our agreement?" said Gwen, tapping her chin with her index finger. "Oh, that's right! You have to do whatever I say for a whole day! Let's see, what should I have you do first..." mused Gwen. Ben stared at her despondently. Gwen eyed her cousin, still covered in a bit of dirt. "Oh, I know! Ben: You. Need. A. Shower," said Gwen with a determined voice.
"....You've got to be kidding me," grumbled Ben abjectly. Gwen grabbed a hold of Ben's collar and led him back to the Rust Bucket. He begrudgingly acquiesced and walked with her without struggling. Gwen led Ben to the bathroom door and pushed him inside it.
"Alright Ben, while you get started I'm going to find you some clean clothes." said Gwen as she shut the door to the bathroom and left Ben to his own devices. Ben stared at the bathroom door and stuck his tongue out at it for a moment. Stupid Gwen. I smell fine, he thought. He rolled his eyes and contemplated on how stupid Gwen was for a few more moments before stepping over to the tub and turning one of the knobs set into the wall. The sound of flowing water echoed through the bathroom as the bathwater began streaming out of the faucet. Ben grabbed the metal plug set into the faucet and pulled it upward. The water stopped gushing from the faucet for a moment as it redirected itself upward and began erupting from the showerhead. That accomplished, Ben stepped back and slowly began stripping. He took his shirt off, then kicked off his shoes and socks, and then his pants, and finally his boxers. He kicked them all into a pile in the corner of the bathroom before stepping into the shower. He let the warm water cascade over his skin for a moment before scrubbing at his face and hair, knocking dirt loose and letting it wash down the drain. Once he felt the last of the dirt slide off his head, he reached over to the bathroom shelf for his shampoo.
"Hey! Use this kind instead," said Gwen, handing a bottle of shampoo to Ben.
"Oh, okay," said Ben as he grabbed the bottle. He flicked the lid open with his thumb before realizing something important...
"GWEN!" he yelp as he slammed his back against the wall and quickly brought the shampoo bottle to his waist to cover up his privates. Gwen was standing next to the tub, wearing a light purple one-piece bathing suit. She was looking Ben up and down. "What are you doing in here?!" he barked out.
"Settle down dork," replied Gwen calmly, looking Ben in the eyes. "I found you some non-dirty clothes," she said, motioning to small stack of folded clothes sitting on the sink behind her. "But, I figured you should be your cleanest before you put them on. And for some reason, Ben," she said, emphasizing his name. "I get the feeling that you don't try very hard when it comes to showering right?" Gwen lectured. "So, I'll lend you a hand!" and with that, she stepped over the rim of the tub and into the bathtub. The shower water poured over her body, and her bathing suit began glistening. Gwen sighed and closed her eyes as she felt the warm water envelop her. She slowly reached up and pulled the small blue clip out of her hair and tossed it onto the stack of folded clothes. She dunked her head under the torrent of water and ruffled it, letting the water soak in. Her hair darkened slightly as it became wet. Gwen pulled her head out of the downpour and rubbed the water out of her eyes, before opening them and looking at Ben, still pressed against the shower wall with an agitated expression on his face.
"C'mon, pukeface. Shower time!" she intoned to Ben, with her hands on her hips.
"Yeah, I need privacy for that! Personal space and whatever," replied Ben, wet and for the most part naked, save for the shampoo bottle he was using to shield his johnson from Gwen's prying eyes.
"Fine, turn around," replied Gwen. Ben eyeballed her. "Just do it, dweeb," she said firmly. Ben broke eye contact with her and sighed before slowly peeling himself off the shower wall. He twisted his body around so that his front faced the shower faucet and his back faced Gwen. Gwen rolled her eyes at how melodramatic Ben was being. She closed the gap between them and put her hands on his bare shoulders. "Geez, quit being so shy, Ben," she cooed in his ear. "You've actually got a decent-looking body when you aren't rolling around in the mud, you know," she said as she trailed a hand down his back, feeling the muscle built up from what seemed like a lifetime of alien fighting. She traced her hand down further, until it rested on Ben's right butt cheek. Ben shivered at the contact.
"Umm, Gwen? Just what do you think you're doIN-" Ben yelped as Gwen dropped to her knees and slid her hand between Ben's thighs. She reached upward, her wrist grazing against his balls as she wrapped her hand around the shampoo bottle and pulled it back between Ben's thighs. She stood back up, holding the bottle.
"Just getting the shampoo," she explained nonchalantly. She turned the bottle upside-down and poured a gracious amount into her hand. She set the bottle down and began working the shampoo into a fine lather, which she then applied to Ben's head. Ben felt his cousin running her fingers through his hair as she spread the shampoo over his head. The scent wafted down from his hair, a sort of spicy strawberry smell that caused Ben to feel slightly light-headed. Ben closed his eyes and concentrated on the sensations he was feeling as Gwen shampooed his hair, but then thought about Gwen herself, wearing that tight, wet bathing suit behind him....
Ben began growing aroused. At first, he was alarmed that his dick was becoming erect because he was thinking about his cousin, but as Gwen continued massaging his scalp, he quickly learned to just accept it. 'What the hell,' thought Ben, now grinning to himself. 'This might be fun after all!' He relaxed his shoulders and let Gwen finish shampooing his hair. When she was done, she pushed Ben's head under the stream of water and watched as the suds trailed down his lean body and into the drain.
"Alright Ben," said Gwen once the shampoo had been washed out of Ben's hair. "Hand me that sponge," she said, pointing to a poofy shower sponge sitting on a rack suspended from the showerhead. Ben pulled the sponge off the rack and held it over his shoulder for Gwen. Gwen grabbed the sponge, but Ben didn't let go. Their hands were touching.
"Gwen," said Ben as he turned his head and twisted his shoulders to look at Gwen. "When you get done, make me scrub -your- body, all right?" he said, with a sort of seductive look in his eyes. Gwen grinned and punched Ben lightly on the arm.
"Sure, Ben. I'll think about it," said Gwen coyly before making a little circle gesture with her finger, telling Ben to turn back around. He complied (after briefly letting his eyes wander down Gwen's chest) and Gwen began soaping up the sponge until it was dripping with suds. She pressed it up against Ben's back and slowly scrubbed against it in wide up-and-down arcs. Gwen ran the sponge over the tops of Ben's shoulders, and across the back of his neck, and then lowered herself to her knees as she drew the sponge down Ben's back, and to his butt. When she reached it with the sponge, she giggled: Ben was flexing his butt! She couldn't really tell if he was doing it voluntarily or not. Gwen bit her lip as she eyed Ben's pert butt, and slowly started trailing the sponge over it, up-and-down, one cheek at a time. When she finished scrubbing at his butt, she drew the sponge down Ben's thighs, and then of his calves. She grabbed a hold of Ben's hips and used them for leverage as she hoisted herself back onto her own two feet. "Alright Ben, time to do the front," said Gwen, her voice a little heavier now. Ben turned around slowly, first bringing his shoulders around, and then swinging his legs in a tight arc as he stood wet and naked facing his cousin. Gwen let her eyes roam downwards from her cousin's face, past his chest and stomach, all the way down to his.....'Woah', thought Gwen as she eyed Ben's cock. It was -big-. Several inches long and pointing straight out. She'd seen him pitching a tent before, in the early mornings or when he was asleep, but right now it was definitely bigger than those other times. "Umm, Ben? It's gonna be tough to scrub you if -that-," she said, pointing at his dick. "is going to be poking me." Ben sheepishly grinned at the attention his "part" was getting.
"Hmm, well, I've got an idea," he said as he eyed Gwen up and down. "You're a little taller than me, right?" asked Ben.
"Yeah, I think so," said Gwen, giving him a puzzled look. "Why?"
"Well, what if we tried this?" said Ben as he put his hands on Gwen's hips and slowly pulled her closer to him. As she was pulled closer, Ben's cock pressed between her upper thighs and the crotch of her bathing suit. He pulled her even closer, until her bathing suit pressed against his skin and his cock was squeezed in between Gwen's warm thighs.
"Ah!" cried Gwen as she felt Ben's dick scrape against her pussy through the thin material of her bathing suit.
"Ah... I figured your legs might be long enough... for me to fit between them," groaned Ben. "Does this.... work for you?"
"Oh... yeah Ben... I think this will work... just fine," said Gwen, breathing heavily now. She forced her mind back into focus and raised her arms to Ben's shoulders and began scrubbing at them with the sponge. But she wasn't able to keep it up for long, as every time she moved her body, her pussy ground itself across the top of Ben's firm cock. She scrubbed faster at Ben's chest as shocks of pleasure surged up from her pussy with every movement of her torso, until she finally gave up. She dropped the sponge to the tub floor and wrapped her arms around Ben's shoulders and rocked her body back and forth, rubbing her pussy against Ben's dick and feeling her clit strain against the fabric of her bathing suit. Ben's body responded in full. Ben squeezed Gwen's hips as he pushed his dick back and forth into Gwen's thighs. The two moaned loudly as they pressed against each other. Gwen opened her eyes and watched Ben amorously for a moment before bringing her face against his and kissing him lustfully. Ben instinctively returned the kiss, opening his mouth against hers as he kissed her with an equal fervor. Gwen broke off the kiss and moaned again from the building stimulation.
"Hah, Gwen, I'm gonna!" groaned Ben as he felt the pressure building in his cock.
"Ah, Ben! I'm!" responded Gwen as she felt like her lower body was on fire.
"AH~!!" the two moaned simultaneously. Gwen's body twisted and shook from the waves of pleasurable sensation that coursed through her as she came. Ben groaned loudly and squeezed Gwen tighter against himself as a torrent of pent-up cum erupted from his cock and shot across the shower as his mind went out of focus. His knees slowly buckled underneath him and the two collapsed into a pile together on the tub floor, shower water now cascading over their bodies as they both breathed deeply.

Gwen opened her eyes and watched Ben softly gasping for a moment, before she leaned in and kissed him on the cheek.
"Alright dweeb.... now it's your turn to wash me."

Author's Notes:
This was an interesting one to write. In my boyXgirl fics, I usually favor narrating from the boy's point of view for the story. In this one, I tried to give Gwen plenty of spotlight. It's not perfect, because I'm still using a third-person narrative, but I think I was able to communicate her thoughts and actions decently. Anyway, this BenXGwen fic has been sitting around on my computer for the past three months as I worked on it bit by bit. I went through several different ideas and drafts before I settled with this one, but I think it worked out pretty well. Another idea had Gwen and Ben having some S&M play with Gwen dominating Ben. There would have been some neat stuff in this, I would have put in a pegging scene, and maybe a scene where Gwen forced Ben to let her measure his dick and take pictures, and other embarrassing stuff. Let me know if you guys are into that sorta thing, and maybe I'll get around to including it next time.

This fic actually carried a few themes of one of my earlier pieces of smut "Fun at the Pool," which featured a naked boy and a girl wearing a purple one-piece swimsuit. I really don't know why, I didn't even notice until way after I had written it into this story, and I was too lazy to edit it into something else. I guess if you liked that one, you'll probably like this one. Anyway, thanks for reading, and any and all feedback is appreciated.
