Brad and Cindy were driving along the ocean highway, the blue sky blazing and the surf pounding casually against the breakers. Brad had on his cutoffs and a white T- shirt, and Cindy was wearing skin-tight white cotton shorts that creased into her crotch as she sat on the seat beside him. Her tits were outlined through the stretchy ribbed top that exposed her bare shoulders, the skinny straps showing that she had no bra on, and as she raised her hands behind her head to adjust her blonde pony tail, her nipples pressed upward invitingly.
"You are looking so hot these days," Brad said. "Since we started fucking I've realized just how sexy my sister is."
"You don't look bad yourself," she said, admiring his strong thighs and the masculine swell of his chest. She knew Brad was good looking and could get many women if he wanted. Of course she realized there were other guys out there as well, but she felt good about the attraction she felt for him. They made a good couple, and the sex was great. It made her horny just thinking about it. She raised one leg on the seat as she partially turned toward Brad, giving him a view of the white shorts stretched tight over her pussy, running a hand down her golden tanned thigh. "I could just eat you up right now," she added as the thought raced through her mind.
Brad moved a hand to his crotch, feeling the erection starting under his jeans, and eyeing the barely concealed pussy under the micro-shorts Cindy was flashing at him on the seat next to him. She moved a hand to her own crotch to emphasize her point, extending her near leg to behind his head, rubbing her calf against the back of his neck while she massaged her own pussy.
Sweat started to break out on his forehead and a grin stole over his face as Brad thought about having his sister eat him as he sped down the highway. He headed toward the freeway and eased back on the gas, letting the car move smoothly through the sparse traffic. A plan started to form in the back of his mind and his dick got hard. Cindy noticed and moved her leg from behind his neck, keeping her hand locked between her legs and feeling the juices starting to stir. "Must sound good, huh?" she said, leaning closer, her wonderful female smell wafting into Brad's nostrils.
He watched her breasts heaving with passion on the seat beside him, the bare nipples pressing tight against the sheen of her tight top, her hand inching up his thigh, teasing at the edge of his shorts. She put her hand on top of his as he massaged his bulging erection. "Let me help with that," she said huskily, lacing her fingers inside his as he worked at his hard-on through his jeans. She was helping him jack off, but the motion was limited.
Cindy moved her hand to undo the zipper of Brad's tight pants, reaching inside to feel the swell of his cock against her groping fingers. He expanded into her hand, feeling his cock meat grow with her touch. As they eased onto the highway, she slipped a finger inside his briefs, rubbing the head of his cock as it poked at his waistband. "Raise up," she said, and slid his jeans down over his knees. She reached inside and wrapped her hand around his warm sweet cock, reveling in the throbbing she felt as she watched her fingers manipulating him inside his cotton underpants. She bent over and nipped at the head of his cock through the cotton, feeling it respond to her soft bite, feeling it like a live thing in her hand.
She slid his briefs down his thighs. "Jack it off," she said. "Pump it up for me."
Brad moved his own right hand back to his aching prick, steering with his left. Slowly he began to stroke it up and down, feeling the first drops of pre-cum emerging at the tip. He looked over at his sister, and saw she had her shorts unfastened and had a hand inside, working at her own cunt as she drooled at the sight of him jacking himself off. He knew he could cum at any time, but wanted to hold back, wanted to cum in her sweet mouth and watch her gobbling his cum all the way down her gasping throat. Then he'd take her for the special treat he had in mind.
"It's ready for you now," he said, "nice and hard and just waiting for your hot mouth to suck it all in."
Cindy crawled toward Brad, working her head between the steering wheel and his lap, positioning herself so she could get his cock into her mouth without banging her head on the hard plastic wheel. She wanted to see stars from sucking the cum out of him, not from getting knocked in the head.
As her lips closed over the head of her brother's prick, Cindy let out a sigh of satisfaction, and Brad bucked his hips, trying to get as much as possible buried in her mouth. He let out a groan and swerved slightly on the road, before regaining control of his driving, if not his dick. It felt good going into Cindy's mouth, and he began to speed up as she sucked more of the shaft into her, licking the sides along the way. A truck passed by and blew its horn. Brad was sure the driver could see his sister sucking his cock on the front seat of the car as they barreled along the highway, but he didn't care. It felt good to flaunt their sexuality in public. He couldn't wait to cum in his sister's mouth.
Cindy pulled on his cock, sucking it deeply into her mouth, letting it plop loudly out of her grasp, only to lick the underside, and tease the piss slit with her probing tongue. The harder she sucked, the faster Brad drove, until he was in danger of getting a speeding ticket. He wondered how they'd explain that one to the officer. Well, maybe Cindy could pay the cop off with a blow job by the side of the road, but chances of that actually happening were slim, Brad knew, and he tried to ease off the gas just as his hard-on was pounding harder in her mouth.
"You want it, don't you Sis?" he groaned, feeling the cum start to bubble in his balls to her insistent sucking. "You want me to cum in your mouth, don't you?" He wrapped one hand in her beautiful hair and pulled her gently off his raging hard-on. She looked up into his eyes, practically begging for it. Her eyes were locked on his in pleading, her lips parted and wet, her breath coming in ragged gasps. He massaged his fingers into her hair and watched her resume her violent sucking.
