Julie licked her lips and gazed down at the head of Bud's cock. Slowly, she lowered her mouth to it and kissed the dark blue flesh where it flared out. Bud dropped back on the bed and moved his hips gently, moaning with pleasure as Julie's tongue began to caress him once again.
'Ohhhh, sis! Ohhhh, you know how to do it!'
Robyn had put a hand down to rub her cunt now. Her pussy was so wet that she was afraid it might be leaking through her panties and her shorts. She snaked a finger under the elastic and pushed between the hot lips of her cunt. Moving her hips forward and back gently, she began to rub her clit.
'Suck it all the way,' Bud said from the bedroom. Julie made slurpy noises as she tried to get as much of his cock into her mouth as she could.
'Mmmmmuuuhhh!' she moaned.
'God, Julie, why don't you let me fuck you?'
'How much?' Julie said, popping her mouth free as soon as she heard her brother ask.
'How much? God, I gave you some money last week, didn't I?'
'How much?' Julie repeated, not changing her expression. She pushed her blonde hair back from her ears. Bud took a big breath and squared his broad shoulders as he sat up.
'Five bucks. It's all I've got.'
'Have you got a rubber?'
'Yeah, bought a fresh pack yesterday.' Robyn was listening to all this with her eyes wide, her mouth hanging open. Again, she had the urge to flee this shocking scene. Her cunt tingled so thrillingly though that she couldn't move. She watched, peeking carefully through the partly open door. Julie had skinned off her top and was wiggling out of her shorts. She skinned her panties down next, her pert, boyish ass quivering as she jumped onto the bed.
'Lick me first, will you?' the cute blonde asked her brother. 'It made me nice and wet when you did it that other time. You go in easier that way.'
'Okay, okay,' Bud said, rolling onto his stomach and wiggling between her parted thighs. Julie bent her knees sharply and her plump cunt-lips parted. Between the blonde curls, Robyn saw the glistening pink flesh. Bud held her pussy-lips even wider with his thumbs and pushed his mouth between them.
'Ohh!' Julie sighed, her slim hips rocking. 'Ohhhh, do it just like that! You know how I love you to lick me, Bud!'
Robyn was in shock. Her mouth was dry and she was breathing harder than ever. Was this really happening? Was she watching her best friend doing the same thing she'd done just a while before with Doug? Robyn tried to leave, but she was frozen to the spot. She was enjoying it!
'You're wet enough,' Bud said, lifting himself up over his blonde sister's body. 'You're wet enough to fuck.'
CHAPTER THREE
Julie opened her knees wider, exposing all of the pink flesh between the plump glistening lips of her pussy. Bud's cock swung heavily as he crawled forward. He bent his head to lick each of his sister's nipples while she arched her back and tried to press them upward for him.
'Don't forget the rubber,' she moaned.
'Oh, yeah. That damned thing!'
Reaching over to the table beside the bed, Bud grabbed a small foil packet and tore it in half. Robyn could see the doughnut-shaped rubber as he pushed it over the head of his cock and unrolled it down the full length of his rigid shaft. The membrane was so thin that Robyn could see his cock easily through it. Julie worked her ass around on the bed like she could hardly wait for the fucking her brother was going to give her.
Bud pressed the head of his cock against his sister's pink cunt-lips and gave a quick little thrust with his hips. There was a slick sound as the head disappeared into the tight circle of her cunt muscles. Julie grunted with pleasure and reached her long arms out to hold her brother's body. She kept working her hips in a circle, her eyes half-lidded as the hot cock penetrated her pussy.
'Ohhhh, Bud! That's heaven!'
Bud held her writhing body, his mouth wetting her neck. He kissed her until her mouth and chin were wet with his spit. He found one of her nipples, pinching it with his lips first, then wit his teeth.
'Whhuuhh!' Julie moaned.
As his sister bucked and wiggled, Bud moved faster too. He was fucking her with a quick thrusting rhythm that reminded Robyn all too clearly of what her brother had done to her that very morning. She was panting, rubbing her cunt while she watched the glistening red cock slide in and out of her friend's cunt.
Julie clung to her brother's shoulders and took huge lungfuls of air as if she couldn't get enough. The rubber Bud wore clung to him so tightly it was hard to tell he was wearing anything. Robyn watched him shave his prick into Julie as far as it would go. A shudder ran through the muscled boy's strong back.
'Ohhh, Julie!' he gasped. His ass gave a flurry of short, sharp jabbing movements. Robyn knew what was happening. The same thing seemed to be happening to Julie. She had her knees thrown wide and her ass was tightly pinched together with excitement.
'Whhhaaaaahh!' she cried, her eyes glazed with lust. She babbled something that had her brother's name included, then fell limp under his plunging, fucking spasms. Buddy kissed her slack mouth, moaning and groaning as he came.
Julie seemed to have fainted. For a moment, Robyn wondered if her friend had hurt herself. But as Bud kissed her face, the girl seemed to come around. Robyn stepped away from the door and backed cautiously down the hall. Her mind was a mass of confusion. She'd come aver to Julie's house to ask for advice, and, instead, she'd seen something that had mixed her up more than ever. Her poor cunt was so wet she could here it sliding together as she walked.
She ducked into another bedroom as she heard Bud coming down the hall. When he'd gone out the front door, Robyn made her way back to the room where Julie had been fucked. Julie was under a sheet now, but her eyes still had that glazed look. Robyn decided she'd try to pretend she'd only just come in. She couldn't let on that she knew her best friend's secret.
'Hi, Julie. Can I talk to you?'
'Oh!' Julie said, sitting up so that the sheet slid away from her tits. Robyn could see how red one of them was. Buddy had sucked on it. It made Robyn's nipples tingle to think of it.
'I hope I'm not disturbing you.'
'How long have you been here?' Julie asked, giving Robyn a funny look.
'Not long I…' But Robyn's cheeks flushed and she knew by the look on Julie's face that she'd given herself away.
'You saw what Bud did to me, didn't you?' Julie said.
Robyn looked down at her hands. 'Yes.'
'You're not going to tell anybody, are you?'
'How could I?' Robyn blurted. 'The same thing happened to me!'
Julie grinned, then took one of Robyn's [missing text].
'You mean Doug did it to you too?'
'Yes! It was awful!' That wasn't exactly how Robyn felt, but it seemed the right thing to say.
'I thought it was awful the first time,' Julie whispered. 'Now, I kind of like it. I hope you don't think I'm a bad person for saying that.'
'Of course not.' Robyn was uncomfortable. She wished the subject had never come up. She could smell her friend's musky cunt and see the smears of spit on her shoulders where her brother bit her while they'd fucked. It made Robyn tingle. She wasn't sure she should enjoy the tingling feeling.
'I wonder if there is anything wrong with doing it with your brother,' Julie murmured.
'Of course there is. It's incest.'
Julie wrinkled her nose. 'Oh, I know everybody says that, but really there's not much difference in doing it
