Robyn didn't know where they were. The car had stopped bumping so much and that was better. She could lick her uncle's cock-head better that way. She put her tongue against the opening in his skin, touching that small area of his tip as she watched his thigh muscles tighten.
"Damn, you sure know how to tease," Allen said, shifting gears. The car moved on, more smoothly now. They had reached the highway, Robyn thought. They were pulling onto the entrance ramp to the interstate. The car accelerated evenly and her uncle shifted again. Robyn used her thumb and finger to slide his cock-skin back.
As more of his cock-head was exposed, Robyn ran her tongue down the inflamed swollen flesh. She petted it lightly, letting plenty of spit drip down to lubricate her lips. Allen was breathing fast and his hands were tight on the wheel.
"Damn!" he murmured.
"You're hot," she said. "You almost burn my tongue."
"Oh, baby!"
Robyn opened her lips wide and let his cock fit deep into her mouth. But she only let the tip touch the inside of her cheek before pulling her lips away again. Then she used the corner of her mouth to squeeze the plump throbbing head. It was slicker than anything she'd ever touched, except her pussy. She curved her tongue into a deep trough and pushed it forward and back along the underside of her uncle's prick-shaft. He gasped then and put a hand on the back of her head.
Robyn didn't mind. She let him push her gently up and down. This bobbing motion made her lips slurp noisily around her uncle's cock-shaft. More spit dribbled down. Her tongue wallowed hotly across the head of his prick, petting and teasing him until suddenly the car swerved.
"Nearly lost it then," Allen panted. "You sure know how to get to a guy."
"Mmmmn," was all Robyn could say in reply.
She was enjoying sucking her uncle more than Doug, even. His cock was bigger and hotter and slicker at the tip. The flesh there was so smooth that it was more like the inside of her cunt than anything else. She ran her tongue around it, fitting into all the little hollows, stroking all the spongy bumps. She was especially interested in the two lobes just under his tip. They seemed the most sensitive to her licking.
"Honey, you're killing me!"
"Are you gonna come?" Robyn asked, popping her moth free and looking up at her uncle with wide innocent eyes.
A huge truck was passing them at that very moment and the horn bleated, Robyn saw a man leaning out of the window and staring down at her with an excited smile. He said something to his partner and the horn bleated again. Allen slowed and let the truck go on past.
"They would have seen you anyway. Damned trucks."
Robyn realized just she must have looked to the men in the truck. Allen's cock was in her hand and his prick-tip was smeared with her saliva. Her mouth was wet too and her red curls tumbled down over the front of her bikini. The truckers would probably be talking about it for months.
Robyn smiled sexily at her uncle, enjoying the worshiping look in his eyes. She watched him watching her as she touched his cock-head with just the tip of her tongue. Again, she stretched his skin back, watching the shape of his slick cock head become exposed. As more of it showed, she let her soft, curvy mouth slide down to take the place of Allen's foreskin. He thrust his hips around in the seat.
"Ohhh, suck it deep, honey. I love your mouth on me."
Robyn let his cock slide along her tongue until it was at the very back of her mouth. She took a breath and bobbed her head still lower. His cock-tip pressed between her tonsils and somehow she managed to keep from choking. But she did gag a bit and her body bucked convulsively as her throat closed around the hard, hot cock.
"Jessusss!" Allen gasped.
Robyn bobbed faster, letting his prick almost leave her mouth each time she lifted her head, letting him go into her throat as she dropped down. The sound of her sucking was loud and sloppy and her cunt ached in sympathy. She wished somebody were doing the same thing to her while she sucked him. She'd heard of that before. Some people referred to the position by a number. She couldn't remember just exactly which number it was.
"Honey, I'm gonna come pretty soon. If you don't want to swallow it, I can understand."
"Mmmmuhhmmm," Robyn sighed, trying to tell her uncle that she didn't mind at all. In fact, she was looking forward to the strong spurts of salty cum. She was excited by the thought of it drenching her mouth.
"Uhhh, ohhhh, Robyn, baby! Ohhhh!"
Allen was squirming around something awful. Robyn clutched his cock and jacked the skin up and down while she sucked powerfully on just his tip. The spongy meat throbbed against her teeth. She nibbled and sucked him, her nostrils flared with excitement as she felt the jerking rhythm of his excitement grow.
It was thrilling to suck Allen! His cock was throbbing and filling her mouth. His tip was getting enormous. Robyn ran her tongue around his cock-head furiously, sucking and licking and biting him until the poor guy could hardly steer the car. She felt him pulling over and stopping. Now the sound of her hungry mouth seemed even louder than before.
"Robyn!" her uncle sighed and his breathing sounded suddenly ragged. Like he couldn't concentrate on anything but what she was doing to his prick with her mouth. Robyn nursed at that bulging, blood-engorged knob with all her might. She jacked him steadily while she cupped his heavy balls. As she closed her fingers around the twin eggs, Allen shuddered violently.
The spurts were thick and steady. After only a few, Robyn realized that her uncle held more cum than her brother did. The white jizz exploded from the corners of her mouth as she sucked him. She rolled her head around, rubbing the head of his cock as her tongue darted in and out against the lobes underneath.
"Ahhhh, babeeee!"
Robyn sucked. She sucked until her cheeks were tired and her throat slick from the hot cum that her uncle had spurted. He trembled and his hands petted the back of her head. He trembled again and a huge sigh left his lungs. Robyn bit down on his cock-head, but only a small dribble of cum oozed from the tip. He was finished.
With a slurpy smack, Robyn pulled her mouth away and licked her chin.
"Like that?"
Allen looked at her like he didn't know how to tell her what was on his mind. Then he managed a smile and another sigh.
"Did I like it, Robyn? If I could just remember this moment for the rest of my life, I'd be a happy man."
"You did, like it then?"
For an answer Allen pulled one cup of her bikini top down and sucked her nipple into his mouth. The sudden warmth, the sudden flick of his tongue made Robyn clutch his head. She arched her back and pressed her tit hard against his mouth. She felt his teeth and lips and his tongue!
"That's nice! Ahhhh, that's really nice!"
Another truck went by them, the horn blaring. Allen took his mouth away rom her.
"Too many people around," he said. "But later on I'm going to show you how much I appreciated what you just did."
"Allen, maybe it would be better if we didn't try to do it at home."
"I'm not going to be able to grab you and take you out every time I want you."
Allen put the car in gear and pulled back onto the highway. Robyn wanted to try and reason with him, but gave it up for now. Her nipple was still burning pleasurably where her uncle had nibbled it. She could taste his cum and the taste excited her. She ran a finger down along the crotch-band of her bikini.
"Go on," Allen said. "Don't be embarrassed to touch yourself."
"I couldn't," Robyn said, blushing.
"Look, I understand. You've gotten all worked up and I can't do anything. So do something yourself. I'd like to watch."
"You would? You don't think it's gross or anything?"
Allen laughed. "Gross? Of course not; it would be beautiful."
Robyn sighed and looked down at her tummy. Her cunt was making her bikini a bit wet. She gave her uncle a shy look and stretched the elastic to one side to expose the bright red hair and the lips of her pussy. Gingerly, she fingered the plump swells apart to reveal the glistening pink color inside. A musky smell was blown through the car. Robyn stretched her long legs out and then bent one knee sharply, hooking her heel on the edge of the seat. The pink cunt flesh bloomed outward, revealing the delicate beauty of her young pussy.
"I feel so funny, doing this."
"Do it," Allen said excitedly. He was watching her as much as he watched the road.
Robyn licked her forefinger until the spit made it shine, then dipped into her cunt-lips, touching her clit gently and sliding farther down between the throbbing flesh. She arched her back a little, then humped it down against the seat as her toes fanned apart from the excitement.
She rubbed herself slowly but rhythmically. Her clit swelled up as she stroked herself. When her uncle looked over, she pushed her forefinger against her cunt-hole and felt it give. The muscles opened and she inserted her finger deep, deep into the feverish wetness of her pussy. There was a sucking sound as she drew it out again. In and out, faster and faster!
"Hhuuhhhh, huhhhnnnn," she panted, eyes half-lidded now.
"God, you're beautiful to watch!"
"Ohh, ohhh, it feels very nice!"
"Not as good as my cock though, right?"
"No, it doesn't feel quite that good. But it is nice! I needed this, I guess. Ohhh, I'm getting all itchy. I always come quickly when I finger fuck."
Robyn fanned a thumb across her clit, but the touching was too heavy so she used her fingertip again. She gasped for air now, her lips lurching in the seat, her belly heaving. She pushed her finger deep into her pussy hole again, tightening it around her knuckles.
Uncle Allen had taken a small cassette recorder from the glove compartment and flicked it on. Robyn couldn't bother with being shy. She was breathing so hard that she was sure the small mike must be picking it up.
"Ahhhh, ahhhhh, I'm gonna come pretty soon," she whimpered, her ass plunging on the seat. She'd slipped down until she was practically on her back. Allen held the mike up to her panting mouth for a few seconds, then down close to where her finger was sliding in and out of her pussy.
"Ohh, it's really nice. Ohhh, I love to do this! It's fun having you watch me. I didn't know it would be like this."
"Go to it, baby."
"Uhhhh, uhhhhhhh!"
Robyn thrashed around wildly, the tickling pleasure between her cunt-lips so strong now that she was half out of her mind. Her finger made slick sounds as she finger-fucked herself, sounds that the recorder was picking up. Her panting moans were sexy too. She felt the tickle turn into a maddening itch and drew both knees back against her tits. The cunt juice spilled down, wetting her bikini where it clung between the cheeks of her ass.
"Coming… coming now!" she cried, her hips jerking as she finger-fucked herself in a frenzied, savage way. She had pushed her middle finger in to join the other one and her wrist was bent back sharply as she penetrated her cunt. The thrills peaked quickly. She felt the aching throbs, the breath-taking ecstasy sweep her.
"Ahhhh! Yahhhh!"
Robyn rested with her head against the seat back as her uncle turned the corner and pulled up in front of the house. She had been listening to the recording of herself. The mike had picked up more than she'd thought it would. She could hear very clearly the sound of her finger going in and out of her pussy. She could hear herself panting too and the comments Allen had made.
"Better turn this off," she sighed, hitting the stop button.
"I'm going to listen to it until I've got it memorized," her uncle said.
"Let me go in first. I think I'll blush if I run into Mom while we're together."
Allen nodded and let her run up the walk. Robyn met her mother in the kitchen and tried to avoid her eyes.
"Have a good time swimming, darling?" her mom asked.
"Oh, yes, I had a wonderful time. Allen and I… swam… all over the place."
After supper, Robyn knew she had to take matters into her own hands. Uncle Allen had put his foot against her under the table and Doug kept giving her the kind of looks, that said he wanted to throw her on her bed as soon as he could get her off alone. It was a miracle that neither her mother nor her father had noticed any of this. Robyn wasn't going to take any chances that they might find out something later.
"I'm going over to visit Julie tonight, Mother," the said when Uncle Allen had tried to follow her into the kitchen. "I might even spend the night."
"I suppose that would be all right, darling," her mom told her.
Robyn sprinted upstairs to throw a few things into an overnight bag. Doug came close behind.
"Jesus, Robyn, I was hoping I could be with you tonight."
"I know you were," she said kissing at her brother. "That's why I'm clearing out. We can't start fooling around just any old time we feel like it. Don't you know that incest is, well, it's wrong?"
"Mom and Dad might think so, but…"
"That's what matters. What they think." Robyn put a nightie into her bag and slammed it shut. "I don't want to hang around and have to fight you off during the night."
"But what am I going to do?"
Robyn laughed. "Beat your meat or something. Won't that help?"
Doug pouted. "It just won't be as good." He looked back into the hall, then pulled the door shut. "Couldn't you just do something for me real quick, Robyn? Just to kind of tide me over?"
"You're crazy. What if Mom came upstairs while I was doing it?"
"Just jerk me off," Doug pleaded. His face looked miserable and Robyn could see the way his pants were all pushed out in front.
"Damn." She bit her lip. "Pull it out then. I'm not going to take too long."
Doug stood by the door while Robyn grabbed his cock. It was damp and hot, and when she began to jack the skin up and down, Doug panted happily.
"That's it, Robyn! Faster!"
Robyn jacked as fast as she could, but her brother couldn't seem to quite make it to the point of coming. He thrust his hips around and moaned a lot, but she knew her efforts weren't going to help.
"Look, I've got to go."
"Suck it a little, can't you?"
Robyn got down on her knees and sucked her brother's prick into her mouth. It seemed to grow big fast now. She guessed that after having a girl's mouth, a man preferred things that way. She sucked him strongly, trying to pull the cum from his balls by the force of her suction alone.
Robyn's cheeks were dimpled in and her tongue slurped along the underside of Doug's prick. He trembled and held her head with both hands. She felt the throbbing pulse of his excitement and sucked faster.
"Ahhhh, ahhhh, yeah! That's it, Robyn. Don't stop now!"
Her brother leaned against the door while she bobbed her head forward and back, forward and back. Spit leaked off her chin. She was becoming excited herself now. She always did when she sucked a cock. Her panties clung damply to her cunt hair. She breathed rapidly through hit flared nostrils.
"Robyn!" Doug gasped, his hair falling in his eyes. "Ohhh, Robyn, I'm gonna come!"
