Baxter Family Roadtrip

Chapter 3: Heat

One Week Later

It was a scorching summers day in June, and heat shimmered off the black top of the I-10 outside Houston. A SUV cruised across the dry, grassy landscape. As the sun beat down on the vehicle, Caitlin, the youngest inside at 21, felt a sheen of sweat on her arm. She leaned over to roll down the window. "Leave it" said the guy next to her. "I like the heat".

She shrugged and withdrew. As she did so, a small splash of white goo on her hand caught the light of the sun. Pulling it up to her mouth, she swiped the goo off with a quick lick. She felt a familiar taste and pushed it around her mouth with her tongue.

Next to her, she could hear a continuous "schlip, schlip, schlip" sound, punctuated with the occasional groan.

Her brother, Luke, was hard at work. His jeans had slipped around his thighs, allowing his large cock to expose itself to the humid air. He was rubbing, slowly and smoothly, his eyes focused on the porn playing on his tablet. He clicked up the volume.

"Oh yeah, that feels so good you stud. Fuck me like that!" The tinny sound of tablet speakers echoed around the inside of the car. Caitlin fixed her eyes on the tablet as well, and reached her fingers down to the zip of her denim cutoffs. On the screen she could see a mature blonde, Jessica, dressed in only a skimpy bra. She was showing off her thick body to the camera. Her loose blonde hair cascaded around her shoulders, and as she pulled an exaggerated face, she moaned a series of encouragements at her 'son'. "Mommy likes it so much! Are you ready to fuck Mommy?"

"That's Jessica DeVeux, right? She's your favourite." Caitlin asked.

He glanced at her. "Yeah, she's so freaking hot. Her ass is crazy." His sister was slumped in the corner of her seat, half resting on the door. Her fingers were playing with the fabric of her panties, cutoffs discarded on the floor.

On the tablet, slightly obscured by finger prints and dust, Jessica changed positions, leaning forward and displaying her ass to the camera. "Oooh do you like that? Do you like seeing Mommy's ass?"

Luke began to breathe deeper, and crouched forward slightly, gripping the tablet with one hand, and his cock with the other. "Mo-Mooom", he said loudly his voice quavering as he pumped back and forth, "I need some help with this".

Tracey, his mother, was in the front seat, her hands resting on the steering wheel as her eyes watched the road carefully behind sunglasses. "Aww, I know honey, we'll be in Houston soon, and then we can take a break, OK?"

He pumped once more, eyes fixed on the screen. Jessica's moans turned wild and ragged, still audible over the slapping of flesh on flesh. "No, Mom. Now." his voice was cold and dead even.

"I coul-" Caitlin started.

"I said Mom. Now."

Tracey checked her mirror and signaled left. 'He's in that mood again.' she thought 'In the past two weeks he's been getting quite commanding'. She felt a familiar pang of arousal inside her. Her legs had found themselves rubbing together for the past few minutes. The constant loud moans and sex noises she could hear were sending tiny pleasurable pulses through her pussy. Her eyes flicked up to the rear-view mirror, and she caught sight of her son's large erection, covered in a generous load of precum. She gently bit her lip. "Honey, just hang on, Mommy will sort it out, OK?"

Reaching down to the hem of her skirt, she pushed a hand underneath. With her right hand, she pulled the steering wheel, speeding into the next lane. A blue Toyota dropped back slightly, the driver hitting its horn in frustration.

Caitlin was now rubbing her fingers fast over her clit, matching her brothers pace. The siblings sat masturbating side-by-side, watching the action unfold on the screen in front of them. Jessica was on her back now, her tanned skin standing out from a white bed sheet, as a dark-haired guy leaned down and began to eat her out. "Oh fuck yes, honey." Her head rolled backwards. "You're su-such a good boy for Mommy".

"Is that her real son?" Caitlin asked.

Luke didn't look up. "Yeah" he muttered. "She lives in an Oedipal Zone, someplace out east. She makes homemade stuff now, she used to be a big company star."

Caitlyn thought about the idea of making porn for a living, and her body tingled at the possibility. She went deeper with her fingers, pistoning in and out of her pussy. "You jealous of him?" she asked, trying act like she wasn't massively turned-on.

"Jealous? Nah, you girls are more than a match. But that ass..." He grinned, and as she watched him, she felt a smile touch her lips too. Caitlin liked seeing her brother like this, mid-flow, so fixated on the task in front of him, working deep, powerful breaths. She had her fingers inside her pussy, working herself more and more. "Mom!" Luke said loudly.

"Honey I'm coming, don't worry" Tracey said, as she pulled off the highway onto a road shoulder. It was graveled, with a small grass slope on one side. One large truck sat across from them, but it didn't look like anyone was inside.

As the tire-on-gravel noise stopped, the slapping of flesh and moaning got louder. Tracey jumped out of the car, slamming the door, causing the vehicle to rock slightly.

In the passenger seat, a girl yawned, opening her eyes and stretching her long legs. Ana's lithe 26 year old body struggled into action. She flipped down the sun visor above her, and caught sight of Luke pumping his cock. "Oh" she said with surprise, and turned in her seat to take in the scene before her.

Caitlin was rubbing her clit with one hand, and pumping her pussy with two fingers of the other. Her hair was splayed out, with strands in front of her face, moving a little every time she breathed. She let out a small whimper as she eyed her brother working his cock back and forth. Luke was reclined in his seat, and had dropped the tablet beside him. The woman on the video was lying face down, breathing heavily, with her large ass splattered with drops of cum.

The car door opened, pulling in fresh air and traffic noise as cars rushed past them. Their SUV was set back slightly from the road, but if anyone slowed down, they'd be able to see the naked bodies inside from an easy distance.

Tracey was apologizing as she crouched inside the car, "Oh honey look at you! Goodness, you're all backed up." She reached out and grabbed his cock, gently lifting his fingers from it. "Hush now, Mommy's here, it's all-alright, OK?". Luke closed his eyes and began moaning as his mother rubbed a hand up and down his cock. Precum seeped onto her skin and she fished out a tissue from her pocket, her bracelets clacking together on her wrist. "What have I told you about being messy?" she said.

Luke's eyes fluttered and his voice was slurred "Yuh-you were..."

Tracey's voice melted like butter, and she leaned down to be eye-level with him. "Oh I know, honey, I'm sorry. Mommy was busy driving."

Luke's vision dropped to her cleavage, now at perfect height for him. His mother pulled at her dress straps, letting her bra-less breasts bounce into the open, and Luke reached out to grab them. As he began to squeeze, she let out a little "aww". 'Gosh, those hands feel good' she thought 'and the three morning handjobs were nice, but this is what I'm really after.'

Awkwardly she climbed into the car, and on top of his well-built body. She shut the door behind her, as Luke started tugging at her panties, unable to get them off in the tight space of car. She began struggling on top of him, trying to make some room, as her legs rubbed together. It felt good, but she was excited now, and as her breathing got quicker, she felt a warm wetness between her legs. She needed more.

As she was about to tell him to be gentle, when he grabbed at her panties for a third time, pulling hard. With a loud rip, they split in two.

Caitlin gasped and began rubbing her breast, still covered in a pale pink t-shirt, her fingers moving frantically inside her pussy.

Luke grabbed his mother by her hips and pulled her down onto his cock. She cried out with a small "Oh!", and bounced upwards from the impact. Luke was already moving to meet her, pumping his cock inside her fast and hard. "Yes, Mom, you feel so good" he said loudly.

The video had ended, and the only sounds inside the SUV were the slapping of skin from Luke and his mothers fast-paced fucking, along with the two sisters masturbating.

Ana had long since moved her fingers down into her panties, and was playing with her pussy. Her body was twisted round to see into the back of the car, but her mothers body was blocking Luke. She looked over at Caitlin, and they exchanged a look, Ana raising an eyebrow.

She couldn't help thinking that Luke was getting, if anything, more sexually active than usual. While he enjoyed having sex with his mother regularly, this was their fourth session in one day, and she had never seen him force Mom to have sex on the side of the road. 'Ditching Dad must have done wonders for his libido' she thought idly.

Then her mother dropped down to her knees, and took her sons cock into her mouth, which gave Ana a clear view of the action. Her other thoughts drifted away and she began aggressively rubbing her clit.

Tracey pulled Luke's cock from her mouth and breathed deeply. "Does that feel good, sweetie?"

He moved his cock back towards her and she took it with a throaty, sucking sound. "Yeah, Mom, just keep doing that" he said.

There were muffled sounds coming from her throat "Hmk du yuh sah?" the sound clearly a question.

"Ugh, *please*, Mom. God." he rolled his eyes.

He could see her eyes brighten and she let out a happy noise - at least Luke thought so, it was hard to tell - and pulled his cock into a deepthroat. He may be an Alpha, but that was no excuse for bad manners, his mother had always said. It had taken a few years of work, but the message had finally seemed to stick with him.

The heat inside the vehicle was now stifling, both Luke and his mother were now sweating heavily. A sheen of sweat on Tracey's face reflected the hot southern sun and her light summer dress stuck to her skin. Not that Luke cared, as her fat breasts were loose. The straps hung by her sides, swinging as she moved.

She popped Luke's cock from her mouth and took a deep lungful of air. Luke groaned, and moved his ass forwards, shoving his cock near her face for the second time.

"No, honey, Mom-" she breathed again, "Mommy needs this" she said, with one hand on her pussy.

Luke nodded, and, gently, he flexed his arms. He slowly moved her up onto his lap, before grabbing his cock, and rolling a condom onto it. Carefully, he pushed upward, and when making contact with her pussy, shook his cock once, making a circle on her skin. His mother let out a light moan, her body shaking with anticipation.

With a rapid thrust he shoved himself into her. Tracey's eyes flickered once and she cried out. He moved out slowly, and then in again hard. Out and in. In and out.

Caitlin was the first to cum. Her back stiffened, and she quietly slumped forwards, slowly leaking fluid onto the car seat. Mindful of her mother next to her, she grabbed at her cutoffs, looking in vain for a tissue. "Fuck" she whispered, looking into an empty pocket.

That roused her mother. She had been moving up and down with ease, each movement gently bouncing the seat, and her son, below her. She paused for a half-second.

"Caitlin Baxter!" she choked out "Language!"

"F- I mean sorry, Mom. I need, uh..." she pushed her fingers through the liquid uselessly, as if she could put the fluid back inside her.

"There's tiss- OH!" her mother was cut off as Luke began pumping again, his nostrils flaring as he worked his hips. She made light yelping moans, "Oh, oh, oh", every time their bodies smacked together. Bucking off her son, her body pressed into the seat in front of her, letting out a loud string of noises as she orgasmed.

"In the back" Ana cut in, and gestured toward the back of the SUV. She watched as Caitlin climbed over the seat - leaning over, the twin cheeks of her pale ass gyrating as she moved. Ana's eyes lingered there, before drifting back to her Mother, whose body now faced hers. She watched her brothers cock re-enter her, rocking back and forth inside the MILF's body. She quickened the pace of her masturbation. "You got them?" she asked Caitlin, "Mom's gonna need them" she said under her breath.

Luke grabbed his mother hips and pulled her down, hard. Grunting, he rocked her again, slightly back and forth, and reached up to paw at her left breast. Tracey was out of breath, "Th-that's it honey, there we go." He jerked upwards, letting out a series of grunts.

"God- Mom-" he spat out, sweat dripping from his brow. "So... fucking... good."

His mother rose off him, leaned down and began licking his cock. "There we are, honey" she said, ripping off the condom and tonguing him. She looked him in the eyes, "It's OK now".

"Hey!" Caitlin said, sliding back down into her seat. "Mom, you can't let him say that!" She had a high pitched tone, the irritation clear in voice. She had retrieved a handful of tissues, and started rubbing them across her pussy.

Her mother sighed lightly, "Your brother was just excited that's all" she said dismissively, and gave a long lick up the shaft of his penis. "Besides you're twenty-one and he's twenty-three. You should both know better by now."

Caitlin let out a irritated sigh. "Young lady!" Tracey said with a stern voice, "Help your brother and pass me some tissues". Caitlin passed over a cardboard box.

There was a moment of relative quiet as the three in the back of the car began wiping themselves off, and Caitlin shimmied back into her tight cutoffs. "Gosh it's hot" Tracey said, pulling at her dress to wick the sweat off.

Luke reached his hand over and pulled the door handle. Cool, fresh air swept into the car. "Thank you honey" she said, and clambered over him to get out. Once free, she stepped onto the gravel, rubbed her back and stretched slightly, trying to clear the stiffness. 'I should take up Yoga again', she thought.

Grabbing the car door, she leaned in to kiss Luke on the cheek. He relaxed back into his seat, raising his arms above his head and let out a contented sigh. His jeans lay around his ankles, and his exposed penis, gradually softening, felt warm in the hot sun. Caitlin pulled her phone from her cutoffs, and began texting her friends.

Tracey dropped back into the drivers seat, and tried to smooth down her wrinkled dress. She looked over to Ana, who sat beside her and watched as her daughter continued to rub at her pussy. "Aw, honey" she said "Did you not get a chance to finish?" She rubbed the exposed skin of Ana's leg with her hand. "Poor thing..."

"It's OK, Mom" Ana said, and unzipped her purse, retrieving a small piece of plastic, shaped like an egg. She touched it to her pussy, before gently pushing it inside. A thin wire led from the egg to a plastic controller. "Would you like to?" Ana asked, presenting the controller to her.

Her mother took the controller and pressed the START button. Ana let out a small "umpfh" sound and her legs twitched. Tracey hit the plus button several times. Her daughter began grinding on the seat next to her. "Enjoy, honey" Tracey said. She put the car key into the ignition and twisted, restarting the engine. The air conditioner flared to life, sending cool air over Ana. She moaned.

Tracey shifted the selector into automatic, and drove the car to the I-10, leaving the gravel road behind.
