Chapter 1

Donna looked at the beautiful dog in the pet shop.

"Oh, I love that dog," she exclaimed excitedly, "what kind of dog is he?"

"That's a German Shepherd," her mother said. "I've been thinking of getting you a dog, dear. Would you like to have him as your own?"

"Oh, yes, yes," she exclaimed, "I would love having that dog."

The pet shop owner shook his head.

"You would have to pick him," he told her. "He happens to be the most expensive dog I have in the place."

Her mother looked about nervously.

"That's the only one I want," Donna insisted.

"How much is he?" she asked.

"It'll cost you two hundred and fifty dollars," he told her.

"That's really more than I'm prepared to pay," her mother shook her head.

"I've got some money of my own, mom," Donna argued. "Let me help you."

"No, dear," she said, "you don't have to use your money. I told you I'd buy you a dog. You need one."

Immediately the pet show owner caught on to the reason why. For Donna had a beautiful body. She had full ripe breasts, a trim waist and long, lithe legs.

"I'll tell you what I'll do," the pet shop owner said magnanimously. "I will let you have that dog for two hundred and twenty-five dollars."

"Please, mom," Donna begged.

"All right," she agreed. "We really can't afford it, dear, but if you want him so badly, we'll get him."

Later that day when she had the dog beside her in her bedroom she was thinking of names for him.

"What are we gonna call you?" she questioned. "It's difficult to think of a name," she mused.

Looking at him she suddenly glanced down between his legs. She observed his penis.

She could hardly believe it was so big. She got down on her hands and knees and reached out. She remembered the time that her brother Bob had asked her to pull on his cock. She began pulling on the dog's penis.

"How about that?" she smiled. "I'm gonna call you Billy," she told the beautiful German Shepherd dog as she pulled on his cock.

The more she pulled on his penis, the more she noticed the juice starting to drip from the head of his shaft. She remembered how it worked when she did it for her brother Bob. She also remembered how her brother Bob insisted that she slip her mouth over his shaft and suck it. She couldn't help but wonder if the big dog Billy would enjoy her doing the same thing.

Laughingly she pulled on his cock and asked him, "Billy, do you want me to blow you?"

The dog's jaw hung slack. Saliva dripped from the corners of his mouth. It almost seemed as if he was answering her in the affirmative.

"All right, Billy baby," she smiled, "I'll take care of you. Let's have a good time, baby," she smiled.

She pulled the dog's big shaft to her mouth and sucked on it. It didn't taste bad.

Momentarily it made her shudder to think she was doing it with the dog.

"Billy," she exclaimed, "I can't do this."

However, he wagged his tail and that made her realize he wanted her to complete the act.

Slipping her mouth all the way over his cock she began sucking in earnest. It wasn't difficult once she'd decided she was going to do it.

She finished him off as he shot her a big load. The dog's sperm juice tasted good to her.

After she'd finished giving him his blow job she got into bed. As she lay there she was thinking. Thinking about what a strange and unusual act she'd performed. She knew her brother would call her awful names if he knew. However, she decided she would never tell him. That would be much too dangerous.

Late that night Bob did come in. He slipped into her room when he'd finished taking off his clothes. Stark naked he pulled back the sheets and got in bed with Donna.

"What are doing here?" she demanded.

"I just thought I'd kiss you good-night, little sister," he smiled.

"I know what you want," she told him, "and it's not decent. We shouldn't be doing things with each other."

"Don't worry about it," he said as be began licking on her bosoms.

It was making her nervous to have him carrying on like this. Nevertheless, she figured that she might as well give in to his lusty desires. If it meant that much to him, why not?

As he licked at her nipples she noticed that her big dog Billy was stirring.

"Oh, Billy," she said, patting the dog.

Her brother Bob looked at the dog in disgust.

"Why the hell do you need to keep that dog in your bedroom?"

"For a very good reason," she smiled as he pulled off her bosoms.

"Tell me," he demanded, "are you always gonna have that dog sleeping beside your bed?"

"I happen to think it's a very good idea," she assured him. "Apparently you feel you have complete access to my body. Well, you don't. I don't like your coming in here any old time asking for sex. What if dad or mom caught you?"

"If we're quiet, they won't," her brother told her as he went back to sucking on her left breast.

He was massaging her right breast while he sucked on her left one. Finally his hand swept down to her pussy. As he sucked on her bosom some more he inserted two fingers into her vagina. She wiggled.

"You like it," he smiled as he pulled his mouth off her breasts.

"Yes, damn it, I do," she admitted. "You know just how to stimulate me. But I resent you."

"Don't resent me," he told her, "Learn to live with me and enjoy it. There's no reason in the world you should resent it."

As he went on licking her bosom she noticed he was starting to make a tongue trail down to her vagina.

Once he was down around her crotch he inserted his hands under her buttocks.

Raising her up he plunged his tongue into her vagina.

"Now, baby," he smiled, "Let's enjoy ourselves."

His tongue plunged into her pussy.

"Oh, sweetheart," he smiled, "you just relax. I'm gonna give you a very good time."

His tongue flipped this way and that inside of her pussy. She appreciated the enthusiasm that he displayed.

"Eat it," he told her, "go ahead, sweetheart. Eat my cock."

He was swinging around in a sixty-nine position. Now his tongue was evading her vagina. At the same time he was insisting that she grab his cock and start licking. It bothered Donna that her brother took so much for granted.

"Go ahead," he insisted, "you know what I want you to do. Now do me."

She pulled his penis to her mouth and began sucking.

"That's beautiful, sweetheart," he told her. "Go down to the base of it. That's it. Come on, fuck."

She moved her mouth from the top of his shaft to the base. Parting his ass cheeks she inserted a finger up his ass-hole.

"Oh, honey," he panted as he momentarily paused in his pussy-eating activity to let her suck on his cock. "You're wonderful. Tonight I want to teach you something different. How about pulling your mouth off my dick and licking my balls?"

Feeling that it was the only way out, Donna pulled her mouth off her brother's penis. She quickly sucked at his testicles. He loved the sensation of her mouth over his balls.

"Nibble on them," he told her. "That's what I want you to do. Nibble on my nuts."

After keeping this up for a while she realized what he wanted next. His ass was wiggling all over the bed.

"Use your tongue in my ass," he told her. "That's it, sweetheart, suck my ass-hole."

She flipped her tongue this way and that. He loved the feeling of her tongue licking on his ass cheeks.

"Now, baby," he told her, "I want you to eat my ass-hole."

All of the sudden her tongue swept up his rectum.

"I like that sensation," he told her, "that's real good. Yes. Just keep it up."

As the tongue pumped up his rectum his whole body quivered with excitement.

"Oh, baby," he told her, "you sure are good at sucking ass. Oh, sweetheart, keep it up."

Donna was discovering what a difficult thing it was to give an ass suck. Her brother's behind wiggled in so many directions that she had to reach out, grip it and hold it in place.

"Oh, suck my ass," he begged her, "suck ass. That's what I want you to do. Suck my ass-hole. Come on, baby, suck my ass-hole."

She let her tongue slide as far as she could up his ass-hole. At the same time she reached for his cock and pumped.

"That's it, baby," he told her, "suck and jerk. Oh, baby, suck ass. Jerk my cock. Now you're doing it. That's the way I like it. Oh, yes, eat my ass out. Pull on my prick."

As she continually ate his ass out and pulled on his cock, she realized just how close he was coming to climax.

"Oh, you're wonderful," he told her. "Yes, baby. That's just the way I like it."

Her tongue continued invading his rectum. And at the same time she did her thing with her hand on his penis. She was pumping vigorously now. She enjoyed the sight of Bob's balls pulling up with every upswing of her hand.

"Baby, I'm gonna feed you a good load," he promised her. "You just keep pulling. That's the way you do it. Oh, yes, sweetheart, just keep pulling on my dick."

She went on pulling on his penis. He was becoming more and more excited every second.

"Now, honey, go back to the top of my cock. I want you to suck me off."

Pulling her tongue from his ass-hole she quickly licked to the top of his shaft. Slowly slipping her lips over his cock head she sucked.

"Eat it," he told her, "go ahead, Donna. Eat my dick."

Donna's mouth moved magnificently up and down his saliva-slickened penis shaft.

"Ohhh," he moaned in delight. "Yes, baby, that's the way I want it. Now you're doing it. Ohhh, ahhh, yes, yes. You're getting me closer. Keep it up. More, baby, more. Don't ever stop."

She went on sucking. She knew it wouldn't be much longer until she brought him around.

"Oh, baby," he panted as he pumped his penis all the way down her throat and shot his gun off. "I'm cuming. Suck that juicy dick. Suck every drop of it. Yes, suck my cock off. Suck it, baby, suck it."

The hot white cream erupted in her mouth. She gulped hungrily.

"Ohhh, ahhh, yes, yes. Suck it off. Suck it. Oh, you dick eater, suck my cock off."

His hands held her in place.

"Ohhh, Donna, baby," he smiled as she finished nursing his cock off. "You sure know how to lick my joy stick."

When his sister pulled her mouth off his penis she patted her pussy.

"Come on, pussy eater," she told him, "it's time for your tongue."

He went back to her fur-trimmed triangle. He quickly slid his hands under her ass cheeks.

"Now that I've discovered eating ass," she laughed, "I want you to suck on mine."

It was a pleasure for him to eat her ass. He had no inhibitions. Pleasure was his principle.

Her brother's tongue slipped around her smooth, bare behind. Finally he let his tongue flip up her ass-hole.

"Eat my ass," he begged her, "go ahead.

Stick your tongue in it."

His tongue surged up her rectum.

"Finger my pussy while you're eating my ass," she demanded.

He did as she told him to. His finger work was fantastic.

"Oh, yes, yes," she enthused, "I like that. Now you're doing it. Come on."

She was pleased with his actions.

When he had finished giving her a good ass sucking he knew it was time to dip his tongue inside her vagina.

His tongue soon pumped into her pussy. He flipped it vigorously this way and that. She enjoyed the way his tongue licked and lapped and sucked on her.

"Eat me, Bobby baby," she panted, "that's the way I like it. Oh, honey, suck your sister's pussy. Oh, yes. Come on, pussy eater. Now you're performing."

Bob licked up and down on her erect clit. Then he nibbled. She could hardly stand the erotic excitement.

"I'm cuming," she panted, "ohhh, yes, yes. I made it."

All at once she was juicing. This was the erotic moment she had waited for. Reaching down she gripped her brother's head and held him over herself.

"Oh, love me," she moaned in a passionate frenzy, "Love me."

She raised her legs over his shoulders. Pressing her thighs against his cheeks she gloried in his tongue job.

When Bob withdrew his tongue from his sister's pussy he asked for a compliment.

"Would you say I'm a good pussy eater?"

"Oh, yes," she assured him, "you really are."

There was only one thing that was disturbing her brother now.

"I can see I got you all excited again," she told him, "and what are we gonna do about it?"

"That, my love, is a very good question," he assured her.

He enjoyed the fact that she was willing to stroke him.

"It feels real good when you pull on it," he told her, "it really does."

Bob had an idea. She had rolled over and the sight of her round ass cheeks was getting him stimulated. He let his hand reach over so he could stroke her behind.

"There are many ways to fuck," he told her quietly.

"What do you have in mind?" she asked, eyeing him suspiciously.

"You've got a real smooth ass," he told her frankly.

"Have I?" she smiled.

"Yes," he nodded, "and if you would just let me fuck it you might like it."

"We've been over that before, Bob," Donna reminded her brother, "and I said no way."

"Didn't you enjoy having my tongue in your ass-hole?" he asked her curiously.

"Yes, I did," she admitted, "but that was different."

"Why was it different?" he demanded.

"It just so happens, little brother Bob," she said testily, "that your cock is considerably larger than your tongue."

"So you've noticed," Bob smiled as he reached to his own penis and measured it with his fingers.

"Yes," she told him frankly, "and I'm not about to take that big pecker of yours up my behind. I hope you don't mind."

"I mind a lot," he assured her. "I'd have a hell of a good time if you'd let me ball your ass-hole."

"No way," she insisted again.

But Bob was not going to be put off. All at once he pushed her hand away from his penis where she was stroking him and he moved around and suddenly straddled her. Now that he was in a good position to insert his cock, he prepared to do so.

"Relax," he insisted, "and I'll just slip it to you."

It was much easier to talk about relaxing than to achieve it. For Donna was tense. Having his huge shaft without any lubrication to help make its anal entrance did not exactly please her.

"The least you can do," she told him frankly, "is put some lubrication on that big ole dong of yours."

"I don't want you talking about it like that," he insisted. "I'm proud of my dick."

"I can tell," she said, her body shuddering as she imagined the pain that would result if he shoved his huge shaft into her.
