John Kellerman: Spread wide sister

"Uhhhhh, ohhhh, this is it! Ohhhh, Doug, I'm coming!"

Her ass did a wild dance against the mattress. She could feel cum dripping down her sides. She could feel Doug's mouth lolling wetly against her nipple. Robyn bucked violently now, fighting for that razor-edged ecstasy she knew was there. Her brother finger-fucked her deeply as she arched her back and gave a low, animal groan. Her lean body shuddered as if she were being whipped.

"Yuuuuhhhhh!" she gasped, coming hard. Doug was amazed at her convulsions. He seemed to watch her as if she weren't really his sister, but some strange, wild animal. Robyn felt wild. She couldn't control the convulsions of her body as she tossed and kicked on the bed. Doug had rolled off of her and was, prodding her deeply between the lips of her cunt with his fingers. Her muscles squeezed down around his knuckles as she kept coming.

"Ohhhhh, Goddamn!"

"Feel good?" Doug asked.

"Can't talk," Robyn groaned, still bucking. For a long while she squirmed and trembled until at last the spasms had passed and she sagged, exhausted and panting next to her brother's warmth. They were both cummy and the sharp smell made her feel strange. The shock of what had happened was starting to soak into her consciousness.

"Don't cry, for God's sake," Doug said, shoving the top of his pajamas across her belly. "Why don't you take a nice warm bath."

Robyn sat up, her eyes waxy and red. "What we did! Ohhh, Doug, I'm so ashamed! We fucked. We're brother and sister and we fucked!"

"You don't have to start bawling!" Doug said, looking round nervously. "Mom and Dad don't ever have to find out. If you don't go blabbing."

Robyn whimpered, burying her face in her hands.

"Hey, calm down. You're not hurt are you?"

Sniffling noisily, Robyn looked down at her cunt. Her pussy was swollen so that her flesh bloomed out like some strange flower. She touched the tender, fuck-rubbed places.

"…I guess not. It's kind of sore."

"I'm sore too," Doug said. "You were really squeezing me at the last."

A shiver went through Robyn's body. Her cunt was still throbbing with the afterglow of the pleasure she'd felt. She got up and walked unsteadily to the door and down the hall. She was still sniffling, but starting to calm down a bit now. She ran herself a tub of hot water, quickly soaping the drying cum from her belly. Her nipples were sore from where her brother had kissed them.

"I can't hardly believe it," she kept mumbling. "Doug fucked me. I fucked Doug. We fucked!"

To forget what had happened, Robyn took the money Doug gave her and hurried downtown to buy the purple bikini she'd wanted so badly. Yet, even after she'd taken it out of the store and was on her way through the park, she found herself remembering all the details of what Doug had done to her. She was confused and upset. She wasn't in love with her brother, that was for sure. Yet, thinking of how he'd been so sweet when he'd kissed her, remembering how his cock had felt stabbing into her soft, ripe cunt gave Robyn the shivers.

"I don't know how to feel," she murmured to herself. She knew she didn't want to return home quite yet. She had to think things out. She had to come to some sort of decision about what to do. Her life just couldn't go on as if nothing had happened, could it? She turned up Main Street and headed toward her friend Julie's house. Julie was about her own age and she had a brother too. Robyn wondered if she dared confess to her best friend. Would Julie understand? Most important, could Julie keep the awful secret?

She knocked on the door, but when no one came, Robyn went around back. The kitchen screen was open, so she went in, calling Julie's name. Since her friend's parents both worked, she guessed that Julie was in her room. There was a long hallway and Julie's bedroom was near the end. Robyn started down it. That was when she heard a soft moan and a bed jiggling.

Robyn pressed herself against the wall, her head spinning. The sound she'd heard had been too much like the moans Doug had given when he'd come on her belly. It made her nervous. She almost turned and left the house. When the moan came again, she heard something else too. Something wet and slick. Sucking noises.

"Ohhhhh, Julie, you're doing it perfect!"

Robyn couldn't leave now. Her cunt was throbbing against the crotch-band of her jogging shorts. She began to creep along the hall, getting closer to the bedroom where the sounds were coming from. The door was open a few inches, just enough for Robyn to look in.

What she saw made her bite her bottom lip hard and hold her breath.

Julie's brother was a college boy who'd played high school football and was doing pretty well on his college team. He was big and broad-shouldered and his blond hair hung long over his ears. He was on his back, his big chest heaving. What shocked Robyn most was that he was stark naked and so was his sister Julie. She was kneeling between his parted legs, both hands holding his big cock, her small red mouth sucked tightly around the swollen tip. Julie was a blonde, like her brother and for Robyn to see her lank hair hanging over the light curls around Bud's cock made Robyn feel strange.

For a second, she didn't believe what she was seeing. Julie had always been such a quiet, shy girl. And here she was, sucking her older brother's wick! When Robyn realized this really was happening, she thought of running, of getting out of that house as quickly as she possibly could. She didn't move, though. She was fascinated by the way Julie's small pink tongue teased the head of Bud's cock. It made soft, wet sounds as it curled around the throbbing prick-tip. Julie's lips opened and her head bobbed down.

"Yeah, Julie!" Bud gasped.

Julie let his cock-shaft slide deep into her mouth, then pulled her lips back up his length and finally took her lips away.

"You sure are hard, Bud. You're gonna tell me before you come, aren't you?"

"Can't you swallow it this time?" Bud asked.

"I don't know," Julie whined, making a face, her short nose wrinkled up.

"It doesn't taste that bad, does it?"

"It's weird. I'm just not used to it yet."

Buddy pushed himself up on his elbows. "How in the hell are you ever going to get used to it if you don't start swallowing some?"

Julie shrugged. "I guess you're right. I just feel a little funny about it. That stuff won't make you sick, will it?"

"It never made Hattie Fowler sick and she sucks cocks all the time."

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.
