other's necks. Robyn was still too caught up in the frenzied moment to think about right and wrong. She only knew that what had happened to her was better than life itself.
When Doug lifted himself up on his elbows and petted the damp curls away from her face, Robyn couldn't help but smile.
'I guess we did it again, didn't we?'
'God, it was nice! I can't believe how much I like to fuck you.'
'I wish I could pretend we weren't related.'
'That's what makes it even better,' Doug said, his eyes on fire with the excitement he was hinting of. 'To fuck you, my own sister, really gets me going.'
'It shouldn't! You shouldn't want to even kiss me on the lips!'
Doug kissed her on the lips then, his tongue forcing her to open her jaws until she was kissing him back just as hungrily. Her pussy tightened one or two more times, milking another droplet of cum from his cock.
'You shouldn't have started all this up again,' Robyn said when she got her breath again.
'Mom and Dad are coming back tomorrow,' Doug said. 'They called while you were out.'
'You don't think we can go on doing this while they're here, do you?'
'We'll just have to be more careful,' Doug laughed.
'No, Doug, we just have to stop. If anybody found out, I think I'd die of shame.'
'See, you're more afraid of what people would say than you are of being wrong.'
'I know we're wrong. I don't even have to think about it.'
They lay there for a long time. Robyn knew they should clean up and try to forget it all again. Yet, it was so comfortable to be held in her brother's arms. He rolled her onto her side and kept nuzzling her shoulder, hie cock still inside her pussy.
Robyn squeezed her pussy muscles to keep him there. She knew she was absorbing all his fresh cum and it gave her a thrill to think of it. When Doug finally pulled his cock free, it looked small and limp. He wiped the cum front it with a towel and lay on his back.
'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!'
