Robyn had never realized just how exciting it could be to suck a cock. To know it was her brother's throbbing prick that was pressing against the roof of her mouth made her tremble. She ran the tip of her tongue slowly along the underside again, starting at his balls and working her way upward until she was caressing the flared head with the most gentle, teasing strokes.
Poor Doug! He was gasping and squirming around on the bed like she was torturing him. Robyn enjoyed being the torturer. She knew a man must enjoy doing that to a girl too! To watch her writhe in an agony of pleasure. Like Doug was writhing from the slippery lick of her hot tongue.
'Mmmmmmuuhh,' she sighed, feeling how hard he was. His cock had grown so rigid that it was almost like a flesh-covered bone. His cock-head was still spongy when she pressed the tip of her tongue into it, but underneath it, too, was hard. She licked noisily, sliding her lips to that fat head and see-sawing her jaw. She even let her teeth cut into the tender, plump meat. Doug lifted his ass off the bed and trembled.
He thrust up and down, trying to drive his cock deeper into the softness of her mouth. Robyn pulled back every time he did this, teasing him into more frantic spasms. Doug grabbed for her head, but she pushed his hands away and pulled her lips off of his cock so that only the flat of her tongue pressed against his hard-on.
Doug knew he had to let her have complete control. He lay there like a whipped puppy while Robyn returned to a slow, gentle sucking of his cock. Her lips rode up and down his prick-shaft very lightly now. Her tongue just barely touched him. She knew it must feel like a fluttering of butterfly wings.
'Ohhhhh! Uhhhhh!' Doug gasped. He was shaking all over. He looked tense and his belly was sucked in tight under his ribs.
'Mhhhmmmmm!' Robyn moaned through flared nostrils. The sweet suck of her mouth was sloppy and hot and she knew her brother was about to come. Was she going to drink his cum? Yes, she decided that she was.
'Here it comes!' Doug groaned, shuddering as her tongue pulled his cock into a jerking, quivering spasm. His hands went to her head, but he didn't try to grab her. He just petted the sides of her face while she worked over him, the spit dripping from the corners of her mouth. The sound of her sucking was louder than ever.
Robyn tasted something salty and rubbed her tongue across his tip. A tiny droplet had formed there, then another. Next came the spurting. It was powerful, sending the hot strings of cum into her throat. She gulped hard, her tongue pulling along the underside of Doug's cock, milking him for more.
Doug came with loud sighs, his chest heaving, his knees bent back as he wiggled on the bed while his sister sucked hungrily at his hard cock. Robyn had enjoyed it all up to now, but the taste of Doug's fresh cum excited her more than she'd thought it would. Her pussy was throbbing like the stuff was being spurted inside her. She almost wished she could climb up over him and stick that jerking stiff cock into her pussy.
'Yhhuuuhhmmm,' she murmured, sucking hard.
'Oohhh, Robyn!'
Robyn grasped her brother's cock with both hands so she could roll her mouth around the head again. Her lips made loud, sucking sounds as cum kept spurting and joined with her spit to make everything slick and sloppy. She could feel the rivulets of jism sliding down her chin and neck. She could taste his cum in the back of her throat. She could smell him too. She could smell the sharp, sour aroma of his spilled cum and was wild for it.
'Robyn, God!'
He was still coming! How much more could he possibly squirt into her sucking mouth? Robyn was faint from pulling at him. Her tongue was coated and it felt as if even her tits were smeared with the white glaze that was still dripping from her chin.
'Ahhhh!' Doug gasped, shuddering as if the final spasms had jolted through him. For a moment more, Robyn kept her mouth gently around him. She was trembling with lust now. She felt more depraved and incestuous than ever. She'd just sucked her brother's cock and enjoyed every moment of it.
Taking her time, Robyn eased her lips away. She ran the tip of her pink tongue across her cummy upper lip and rubbed a hand across her tits, smearing the strings of cum that had fallen there. She was glad her parents couldn't see her now.
CHAPTER FIVE
Robyn had been enjoying the company of her uncle. He liked to play frisbee in the park and when they went over there together, Robyn usually wore her new purple bikini. When Uncle Allen looked at her, she felt funny inside. He'd come back with her parents from their vacation at his cabin just so he could see her. At least that was the way Allen put it when he was alone with her.
'An uncle should stay in touch with his niece. That's a very special relationship.'
The way Allen was watching her now as she leaped and ran for the frisbee was exciting her. Robyn was reminded of the way Julie's so-called father, the guy who ran that liquor store, looked at her.
'God, you've got long legs,' Allen said, flipping the frisbee again. It went high and Robyn had to leap. She thought he did this just so he could watch her prance around like a young colt. She felt sexy and pretty in the bikini. It fit her tight as skin. She loved the cling of purple satin material across her small tits and against her cunt. When she threw the frisbee back, her red hair flew.
Allen was tall and muscled and looked younger than his thirty-eight years. He came over to her and took her hand as they walked to the water fountain. Robyn was breathing hard and she let her uncle use his handkerchief to dry her forehead. She hadn't expected him to kiss her!
The kiss came so suddenly that she didn't even try to stop him. His lips had brushed her cheek for only a moment after all. It might have been merely the kiss of an affectionate uncle for his niece. Just as Allen had said. It was what he said later that changed all that.
'Christ, you look good in that bikini.'
Robyn had blushed, gotten her drink from the fountain and walked away. Allen had come after her and walked close enough so that his shoulder bumped her a couple of times. When he touched her hair, she felt definitely as if she were being seduced. Why did she enjoy the feeling so much? Robyn looked up at her uncle.
'Don't you think we'd better go back to the house? I'm hungry.'
'We don't have to go there to eat.'
'Won't Mom and Dad…'
Allen laughed. 'You don't think they worry that I won't take care of you, do you?'
'No, I guess not.'
Allen touched her hair again. 'I love red hair. A red-haired niece. Always been my dream.'
Robyn sighed. It was nice to be admired. Since. Doug had gotten that job at the ice plant he was hardly ever around the house. He didn't dare try to do anything with Mom and Dad there, but he kept saying that they could pull it off somehow. Robyn really didn't feel like taking the chance. To be caught fucking her brother seemed like a fate worse than death.
'You shouldn't touch me like that,' Robyn told her uncle when he put a hand on her waist.
'I can't help it, Robyn. You're a beautiful woman.'
Robyn felt weak in the knees. To be called a woman by someone so handsome and sophisticated as Allen. He was a successful man in life and probably had dozens of ritzy girlfriends. And here he was telling Robyn she was beautiful. She arched her back a little, trying to make her tits appear larger. Allen noticed.
'You don't have to do that,' he laughed. 'They're pretty just the size they are.'
'Too small.'
'Not for my taste.' He smiled at her and licked his lips. Robyn's face reddened to match her hair.
'Uncle Allen, I think I'd better go home.'
'Let's go get something to eat first.' He walked her to his car and Robyn got in. As he drove away, her hair blew and she felt happy and carefree for a moment. Maybe it was silly to worry about her uncle's innuendoes. Maybe he was just teasing her. Still, when he looked at her, she could tell that his imagination was working overtime. This made her more nervous than she'd ever been in her life. She'd done some pretty naughty things with her brother. Fooling around with Uncle Allen seemed far more wicked than that.
