"You know what I'd like now?" he said.
"What?"
"For you to suck me until I'm hard again."
"Doug!" Robyn thrilled, even though she didn't want to consider such a thing. She remembered when she'd watched Julie's red lips melting around the blue tip of her brother's big prick. It made shivers go through her.
"A girl is supposed to like it too," Doug argued.
"Doug, I am not going to suck your cock," Robyn sighed as if to make her decision final.
"I ate your pussy."
She didn't have an answer to this. Doug got onto his hands and knees and crawled up over her so that his prick was dangling down an inch or two from her mouth. She gave him a push and turned her face away. But he just let his cummy cock-head slide along her cheek.
"Please, Robyn, try it. You might dig it."
"What girl in her right mind would dig doing something like that?" Actually, Robyn had been very curious about what it felt like to have something so spongy against her tongue. She squeezed his limp cock between a thumb and finger and looked at it. "It sure isn't very stiff now."
Soft or hard, Doug's cock made her tingle. Boys were so strange. A girl didn't have anything like that hanging from her. She wondered what it felt like for a man when a girl licked his cock. As good as it felt when she had her clit licked, Robyn decided. And that was very, very good indeed.
It was so weird, her brother on his hands and knees, straddling her body so that his cock was hanging there above her mouth. All she had to do was stuff a pillow under her head and reach up for him with her lips.
"Please suck it, Robyn. I'll give you my next ten dollars. I'll give you whatever you want if you suck it."
Robyn lifted her head and stuffed a pillow under it. Her brother's cock rested warmly against her chin. She let her tongue flick out, wetting the underside of his cock-head. Doug squirmed and breathed faster. She licked again, wetting the slick surface. She could taste cum now and decided it wasn't as bad as she'd imagined. Yet, when she thought of swallowing the stuff as it spurted out, she wasn't sure she'd like it.
"Uhhhmmmnmm!" Doug groaned, shifting around above her so that he could thrust against her lips. Robyn tried to keep him from going into her mouth, but suddenly he took her face between his hands and drove his shaft forward. Her teeth parted and his prick tip glided along her tongue. She choked a little before he pulled back.
"Ghhlluuuuhh!" she gasped, struggling to make him stop.
"God, that's good!" Doug groaned, holding her head even tighter as he pumped his ass. He was fucking her mouth! He rolled to the side, keeping her head firmly clutched to he could plunge his hips and drive his stiff cock in and out between her lips. He had gotten stiff so quickly!
"Nooooo!" she moaned through her nose.
Now that Doug had his cock inside the soft, wet heat of her mouth, he wasn't about to pull it out.
"Suck it, Robyn! Suck it hard!" With a kick, Robyn was able to push her brother away and jerk her lips free of his prick. She glared dawn at him and at his spit-glistening cock. It looked so big now that it was hard again.
"I'm not going to do anything if you act like that!" she scolded.
"I got carried away," Doug said, looking sorrowful. "Look, if I just lie still, will you give me another chance?"
"You sure are hot to have me suck you. I'll bet you want to come in my mouth too, right?"
"How much extra do I get for that?"
Doug shrugged and looked up at her like he needed her licking worse than anything in the world. Robyn couldn't help but feel sorry for him. Besides, the stiff heat of his cock inside her mouth had excited her, even though he'd gotten a bit rough.
"Get on your back, I'm not going to have you grabbing me like that again."
Doug's cock had wilted a little in the interval. Robyn took it between her fingers, amused at the crooked sag of the tip. She began to lick it again, using her tongue on all the tender lumps and bumps. It rose slowly, like a flower stem straightening itself. The head darkened into a pretty blue color and the skin grew taut. Robyn kissed the bulging knob and watched her brother's reaction.
"Yeah, ohhhh, Robyn! Kiss it!"
The next kiss was wetter and longer and she let the tip of her tongue just tickle him the slightest bit. Her poor brother writhed there on his back, his lungs filling and emptying, his eyes getting a glazed look.
"You lick good," he said.
Robyn was remembering just how Julie had done it to her brother that day Robyn had sneaked up the bedroom and peeked in. Julie's small, soft mouth had just rolled around the head of Bud's cock like it was greased. It had looked sexy!
Pursing her lips, Robyn let them suck tightly around the head of Bud's prick. He groaned when she did this. When she started rolling her head slowly, he stopped breathing altogether.
"Mmmmm," Robyn cooed, loving the way his cock-tip slid along the surface of her lips. She hadn't used her tongue this time. She didn't have to. The slick, silky, rub of her mouth against Doug's cock-head was enough to drive her poor brother crazy.
"Goddamn!"
"I take it I'm doing this right?"
"Hell, don't stop to talk!" Doug pleaded.
Robyn fit her mouth against his cock again and began to suck gently, her tongue getting into the act. She let it slide out along the underside of his cock-shaft. When she really stretched, she could reach more than halfway back along his length. Doug began to roll his hips, rubbing his ass around on the bed while she sucked him.
Robyn held his shaft firmly in one hand while her fingers tangled in his balls. She could feel each separate egg, so slick in that wrinkled sac. They were full of cum and it gave Robyn a thrill to know that it would take only a little more sucking to have all that jizz swimming around in her mouth.
"Glluuhhhh," she breathed, letting her lips slide down over his cock-head completely. She sucked him deeper, bobbing her head down so that she could feel him touch the roof of her mouth. Her spit leaked down his shaft. Her tongue flicked excitedly against the blood-engorged prick she was eating.
"God, Robyn, don't stop now! Ohhh, use your tongue again! Yeah… like that!"
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.
