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.
