"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."
