Chapter One

 

A lot could happen over a few months time.

The relationship between Mark and Sonia was certainly proof of that.

When Zoe came home from school that May she was looking forward to a couple of long months of relaxing and zoning out. Because she'd gone south to Florida during Spring Break she hadn't seen her older brother Mark since Christmas. And truth to tell she hadn't missed him an awful lot. She considered him shiftless, lazy, and without ambition. The proof of which was that, at twenty-five, he still lived at home and had yet to get his first respectable job.

He was tall, dark haired, and handsome. His hair was too long and scraggly, however, and he was always poorly shaven, as if he couldn't bother to put a real effort into it. He was habitually clad in jeans and sweatshirts or T-shirts, usually dirty or raggedy, and slouched wherever he went, usually with a sulky expression on his face, as if the resentful at the effort required. When seated, he was always slumped down, legs wide.

It was a warm day in northern Florida, but Zoe was dressed for travelling, in a neatly creased pair of dark blue slacks and light blue blouse. They'd gotten a little rumpled on the plane, but were still presentable as she set her things down on the hall just inside the front door and wandered into the big house to see who else might be home.

She was an attractive girl, short and very slender, but buxom and round faced, with large, gray, serious eyes and long, thick reddish brown hair. She moved with a careful, precisely measured stride across the floor. She knew both her parents were still working. Her father was an investment banker, her mother a real estate broker. Both were ambitious people who worked long hours, and Zoe took after them a lot more than Mark did.

When she saw the movement through the big glass doors leading out into the back she suspected it would be Mark laying around the pool, and she was right, but not entirely. She slid the doors back and stepped out onto the deck, calling to him before noticing he wasn't alone.

Or that he was naked.

Or that he was handcuffed.

When she realized what she was looking at she froze, gaping, stunned.

Mark was laying back on a comfortable chaise lounge, his hands above his head. Nothing was unusual about that. It was a classic Mark pose, after all. But now that she was out in the sun she could see that he was nude. His legs were spread, and he had no pubic hair. Perhaps that was the reason she hadn't noticed at first. The lack of pubic hair almost caused her to overlook his groin, to focus on his smoothly muscled chest instead. But then her eyes slid down his tanned body and saw his cock, which was semi-hard, and suddenly realized how shockingly visible all along its long length.

And then, just as she was taking in this shock, the fact he made no move to cover himself led her to another. The metal around his wrists and ankles glistened in the sunlight, and her jaw dropped further.

At first he gaped back. He pulled against the shackles as he instinctively tried to cover himself, and his face reddened. But then his cock began to rapidly harden, to swell and climb up into the air, thick and hungry.

"Hi, you must be Zoe."

The voice was soft, thick and almost furry. She jerked her eyes away, glad of the distraction.

Sonia was a few years older than Mark, and just as nude. She was six feet tall, with a voluptuous body and a mane of long, thick, wild blonde hair framing a model perfect face. Her breasts were large and firm, and small silver rings dangled from both nipples. Like Mark, she had no pubic hair, and her tight, neat slit was quite visible.

Zoe was shocked and embarrassed anew, and jerked her eyes away from the woman's pussy,

"We didn't expect you until later," she said. "We were playing a little game. I hope we're not embarrassing you."

She moved closer and Zoe could see the droplets of water trickling down her breasts as the woman's eyes fixed on her. She felt as though she were a deer under the eyes of a lion, and took a step back, the hair on the back of her neck raising.

"N-No-no," Zoe stuttered, face flame red. "Excuse me."

The woman caught her wrist. "I'm Sonia," she said.

"H-Hi," she said uncomfortably, trying to tug her wrist free without being rude.

"I've been looking forward to meeting you. Your brother has told me so much about you."

"Uhm humm."

She tugged her wrist and Sonia released it, smiling, blue eyes glinting as she raked them up and down Zoe's body.

"Why don't you get out of those and come join us at the pool?" she said, almost purring.

Zoe stared at her, backing away again. "I-I have to put my things away," she gulped.

She turned and all but ran back into the house, ears burning as she hear Sonia's soft laughter follow. She snatched her things from the hall and hurried up the stairs to her room, still in a state of shock.

She fell against her closed door with a groan, closing her eyes, still horribly embarrassed. She had seen Mark naked before, of course, long years ago, but never - like that.

He had an excellent body, she admitted to herself. Clearly someone, perhaps Sonia, had convinced him to start working out. His chest had grown thicker, his shoulders firmer, and he had muscles on his arms and legs.

And a really big cock. That was a surprise. She had never given any thought about her brothers and their cocks, how big they might be. It embarrassed her to even think about it, and she made a soft, disgusted sound as she shook her head and moved away from the door.

Mark would be involved in sick shit like that, she thought, growing angry now. And that woman! She had looked so predatory she was almost feral.

She put her suitcases on the bed and flipped them open, then took out most of the clothes and dumped them into the hamper just inside her closet. She stripped off her top and slacks and dumped them into the hamper, as well, then hesitated. She was hot, and would have loved to go down by the pool and cool off. That just wasn't going to happen, not now.

She slipped off her panties and bra and went into the adjoining bathroom. It was luxurious, like every room in the large house, and contained a whirlpool tub and large shower enclosure. She stepped into the shower, turning the water on to hot, first, then picking up the liquid soap and squeezing a thick mass into the palm of one hand.

She soaped herself up, but her mind was not on what she was doing. Instead it was on the weird scene out back, the memory of Mark naked and shackled, with his big cock hardening under he eyes. Sick!

And the woman, Sonia. She was a predator. Zoe knew that instinctively. She had probably latched onto Mark because he was weak and came from a well-off family. She reminded Zoe of the thirty year old men who came to the clubs hoping to pick up a drunken college girl and "teach her about life".

Neil. He had been just such a man, tall, sleek, sophisticated, or so she had naively thought. She had given into temptation, to flattery, that a "man" had been so interested in her, and soon found herself in his bed being used like a whore.

He had been smug and arrogant as he had used her body, as if he had all the keys to unlock what would give her pleasure, as if she were an ignorant schoolgirl who should be wide eyed with awe at every new thing he had done. She had hated his attitude. Yet worse, she had hated that his arrogance was based on reality.

She had not been a virgin, but her hurried couplings, usually with half drunken boys, had not prepared her for Neil. He had made her come repeatedly, smirking as he did so, and he had used her roughly. She had been sore for a week afterwards. There had been no love in it at all, not even a pretence of friendship. He had wanted to fuck her, and that was all. She was just a pretty piece of ass.

It had been humbling and guilt-inducing. But at the same time it had been wild and lewd and carnal, and she had never felt like she had that night before or since.

He had sodomized her. No one had ever done that before. She had been more than a little drunk, but had been shocked, electrified. She had tried to stop him when she had realized what his intent was but she was a child in his hand and he had simply kept pushing himself into her.

And after the initial pain it had felt good, and she had lain there, dazed, moaning, as he rode her, as he thrust his cock into her ass and reached beneath to rub at her clitoris. He had yanked her hips into the air and fucked harder, and her face had lain against the mattress, gasping, eyes wide, moaning as he thrust himself into her, as his hips beat against her bottom, and had come.

She had been nothing but a piece of ass to him, and yet he had been the most amazing lover she had ever had. Even now, months later, she found herself instinctively rubbing at her pussy as she remembered that evening, remembered how arrogant he had been, how condescending. Embarrassment clouded her memories as she recalled the crude positions he had put her in, and how she had squirmed at the time, feeling ashamed even as she had spread her legs and pushed her sex back at him.

She sighed, her fingers sliding over her body, the soap in hand, and now her skin was slick, warm, moist, slippery. She ran her hands over her breasts, across her erect nipples. She circled them slowly, then pinched and rubbed at them as they began to tingle and throb.

She had been used, like a whore, and it had been the most exciting, arousing and satisfying sexual experience of her life. She could remember the shame, remember how it was wrapped in wicked pleasure as he had toyed with her. God! He had fucked her in the ass! She stroked her finger across her clitoris as she remembered the shame and heat, face down, ass high, the feel of his cock thrusting... thrusting... thrusting into her back opening as a sexual fever swept through her.

Was the woman downstairs, Sonia, creating that same sort of experience for Mark? Was Mark filled with shame and excitement? She had never really thought about her brothers' sexuality, nor cared to. Now she imagined him - that strange powerful body of his - with his big cock, being tamed, being ridden, being used by that - that woman.

And a part of her felt strangely jealous.

A sound made her eyes flick open and she stared, a shockwave rolling through her at the sight of Sonia leaning naked against the open shower doorway.

"You started without me," she purred.

Zoe gaped, then jerked her hands away from her pussy, only to try frantically to cover herself. She felt mortified even as Sonia let out a soft, rippling laugh at her expense.

"Get out of here!" she cried.

"But darling girl, I can touch you in places you can never reach," she said, sliding forward into the shower stall.

"Are you crazy!?" Zoe gasped, face red, trying to cover her breasts and pussy with her arms and hands.

"Such a shy little girl," Sonia purred. "But a nasty one, too. Did the sight of your brother's cock turn you on so much you had to come up and masturbate?"

The suggestion horrified Zoe. Her face burned with shame as the woman stood inches from her, eyes looking down.

She sputtered a denial and Sonia chuckled again. She reached forward and took Zoe's soapy wrists, easily overpowering the slighter, shorter woman, lifting them up and pressing them back against the tiles above her head as Zoe flattened herself against the wall.

"But he belongs to me, little one," Sonia purred. "You can't have him unless I give my permission."

"Y-You're crazy! Let me go!" Zoe gasped, eyes huge.

The woman leaned into her, letting her weight hold Zoe's wrists flat against the wall, smiling, smirking.

"I saw you fingering yourself," she whispered.

"Get out!" Zoe was almost crying with the same and shock.

The woman's face smiled. "Are you trying to give me orders, little one?"

Zoe gasped, and then cried out as Sonia brought her own wet body in and pressed it against Zoe's naked, soapy flesh. It was soft, and warm, and undeniably pleasant.

"If you're horny, little girl, I can give you what you need," she said in a low breath.

'N-No! No! Stop it!" Zoe gasped, wriggling and twisting in an effort to pull free.

Sonia laughed and leaned in close, sliding her wet tongue up along Zoe's cheek.

"Fuck! D-Don't touch me! You... you sick bitch!"
