Chapter 2

Bob was finally persuaded that he should go to the bathroom and get some oil to rub on his penis.

Once he had the plastic container of oil in his hand his sister decided she would help him. She wanted to make sure it was plenty slick.

When his penis glistened with the oil she nodded.

"All right, little brother," she agreed reluctantly, "I guess you can give it to me now."

She got on her stomach. "It would make it easier," Bob suggested, "if you would get on all fours."

"All right," she agreed.

When she was properly positioned he mounted her. He slipped his slippery cock between her ass crack.

"Relax," he smiled as he slowly slid himself into her.

"That's much easier said than done," she told him flatly.

Suddenly she felt his slippery penis penetrating her rectum. With hard, regular strokes he drove into her.

"Fuck, baby," he panted, "that's the way to do it. Come on, sweetheart, suck it. Yes. Fuck, baby, fuck."

With hard driving strokes he was ramming it into her.

"Fuck it," he exclaimed, "that's the way to do it. Keep fucking. Oh, yes. Now you're doing it. Keep it up. Fuck. Fuck hard."

She ground her hips around. He loved the way her hips swung in time to his cock stabs.

"When I drive it to the left," he told Donna, "you swing to the right. It's corkscrew fucking."

Ramming his cock to the left he loved the way she swung her ass to the right.

"Beautiful," he smiled, "that's the way I love it."

It was amazing how Donna could swing her butt when he wanted her to. He was discovering that she was enjoying having her ass fucked almost as much as he was. Bob's balls slapped against his sister's ass cheeks as he went on stabbing into her.

"Come on, sweetheart," he panted, "that's what I want you to do. Fuck it."

It gave a great deal of pleasure to Bob to grip her smooth behind and squeeze her ass cheeks.

"Oh, baby, you're beautiful here," he told her, "you really are. Bend way over. This allowed her brother the erotic sight he sought. That coupled with his plunging penis excited him.

"I'm gonna ram it all the way in," he told her, "and I'm gonna make it. Come on.

With a hard driving cock stab the thrust it high up her ass-hole.

"Fuck it off," he told her, "come on, baby, fuck off."

All at once she felt his juice spurting into her ass.

"Oh, you brought me around," she told him, "that's wild."

It excited her that he had actually gotten her there.

"Oh, baby," he told her, "you're too much."

She was pleased that he had enjoyed having his dick up her behind so much.

Bob pulled out and some of the juice dripped on her buttocks. As he looked at the dog watching, it annoyed him.

"Why do you have to keep that damned dog here?" he demanded.

"Because," she explained, "Billy loves me.

"Have you been doing it with the dog?" he demanded.

"If you must know, yes," she admitted quite candidly.

"I'll be a monkey's uncle," he laughed, "so my sister is a dog fucker."

"I don't like you being crude about it," she shot back angrily. "I happen to love Billy, too."

"Have you ever sucked his dick?" he questioned her.

"Yes, just before you came," she admitted.

"Have you taught him the fine art of fucking your pussy?"

Donna shook her head in dismay.

"You make it all sound so dirty," she told him, "and I don't appreciate it."

"As long as you two are happy, that's all that counts," he smiled.

Billy jumped up on the bed beside her.

"I think you're bothering him," she complained. "He understands a lot more than you think he does."

"Billy is still just a dog," he snarled.

"Billy," she smiled at the dog, "would you like to fuck."

"He would love to fuck," he laughed.

Now that the point had been made, she figured it might not be a bad idea to let him see her naked with Billy.

Donna spread her legs. The dog got on the bed. She slipped a couple of pillows under her buttocks so she could prop herself into the correct position so the dog could get his cock into her.

Reaching forward she gripped Billy's penis. She thrust it over her fur-trimmed triangle.

"Fuck me, Billy, baby," she begged. "Go ahead, darling, fuck me."

The dog plunged his cock into her pussy.

"Oh, wow!" she panted. "That's beautiful. Come on, fuck me, fuck me, fuck me."

With hard driving cock stabs the dog rode into her.

"Oh, wow!" she panted. "That's the way I like. Come on, Billy, fuck me."

Billy was giving her a wonderful screwing. She enjoyed having the dog's cock in her. And her brother Bob found himself getting stimulated watching. His balls itched and tingled.

Reaching for his cock he began pumping.

"It's stimulating you, isn't it?" she smiled knowingly.

He nodded. Now he was pumping with vigorous movements.

"Oh, wow!" he panted. "Does that ever feel good. I love jerking on my dick while you're getting fucked."

They were having a wonderful time.

"Fuck," she demanded, "fuck me, Billy. Stab your big dog cock into me. Let me feel you."

The dog pressed his paws on her shoulders. Wagging his tail he went on balling her.

"Oh, I love it," she exclaimed excitedly, "fuck me, Billy, that's it, fuck."

It didn't take Billy long to get his big dog cock off. With hard and sudden stabs he was penetrating her pussy.

All at once he shot off.

"Ohhh," she panted, "Billy, I love it. That's the way. Oh, fuck me."

The keen pleasure that she was discovering as the dog rode his cock into her increased.

"Oh, sweetheart," she smiled, "you sure know how to stimulate me. That's the way I like it."

Finally Billy pulled his cock out of her.

"I can't believe it," her brother smiled. "You fucked the dog."

"There's nothing wrong with that," she insisted.

She was pleased over her performance. However, her brother was disturbed.

"I want you to jerk me off," he told her, coming back to the bed, "and do it good. Get that hand rhythm developed."

She had pulled on Bob's cock before. But she had never been able to satisfy him. He had developed a certain rhythmic way of pulling on his meat that appealed to him. It just seemed she couldn't pick it up.

"I will try my best," his sister Donna assured him, "but I don't want you making fun of me if I can't do it as good as you can.

Now he watched her. She was jerking with even, regular movements.

"Oh, that's good," he told her, "now you're really doing it. Keep it up."

She was pumping with passion and delight. He was enjoying every fantastic moment of it.

"Keep it up," he told her, "that's how you do it. Oh, yes, sister, keep pulling on my cock."

She was pulling on his penis with hard, driving movements.

"Yes," he told her, "that's how I like it. Keep it up."

All at once she saw the juice surfacing at the small slit at the crown of his cock. She knew what she wanted. Bending over she let her pink tongue tip light lashes across the crown of his penis.

"Suck that sweet dick," her brother begged her. "Go ahead, sweetheart, keep pulling and suck on just the tip of it. There's a trick to it but it's fun."

She kept her hand moving on his penis. At the same time she let her tongue lightly lash across the top of it.

"Suck me off," he told her, "suck me, sweetheart. Get the juice. Keep sucking. Oh, yes. That's the way I want it. Suck my cock off."

Now she wanted to go to the base of his penis. She shoved her hand away and let her mouth slip down the length of his shaft. He leaned back on the bed. His legs were spread wide. She could see his ass close-up as she would move to the base of his penis.

"Why don't you finger fuck my ass-hole?" he suggested.

Using her index finger she inserted it up his rectum.

"Keep that going," he told her, "I love that, oh, baby, you're beautiful. Keep it up."

She was entertaining him now just as he wanted to be entertained.

"Fuck me, baby," he begged her, "that's how you do it. Come on, sweetheart, fuck my ass and eat my dick. Suck. Suck that cock. Keep it up. Don't ever stop. Suck. Suck my juicy cock. Suck it off."

She went on sucking just as her brother instructed her to. At the same time she kept her finger fucking up his ass-hole. She was developing a matched tempo. He appreciated the fact that she was letting her mouth move up and down in regular strokes on his penis at the identical tempo that she was fucking his ass-hole with her finger.

"Oh, wow!" he panted. "I love that. Suck my cock. Suck it, sweetheart. Oh, baby, suck my juicy prick off. Oh, finger fuck my butt. Suck and fuck, sweetheart."

Reaching down he held her head pinned over his cock. He pumped his pelvis forward. His juice exploded.

"Oh, I'm cuming," he groaned in a passionate frenzy, "I made it, sweetheart. Suck my sticky dick. Get every drop. Drain me."

The hot white cum flash flooded her face. It dripped from the corners of her mouth.

"Eat me," he begged her, "eat my dick off. Oh, sweetheart, suck that juicy prick. Suck. Suck that cock off."

Bob's cum always tasted good to her. She liked to suck and swallow her brother's juicy penis. Now and then she did worry about her folks finding out. However, she was glad that their bedrooms were upstairs and their parents' bedroom was located down stairs. This made her relax.

When she finally pulled her mouth off his cock and slid her finger from her ass-hole he looked at her with wonder and delight.

"I don't think I ever could find a woman who would satisfy me like you do. You get me so excited, Donna."

"I'm a natural," Donna laughed.

"You really are," Bob assured her, patting her gently on her pussy.

"Some girls have to be forced to do things," he continued. "They really hate it. It's awful. But, sweetheart, you love it, don't you?"

"To be perfectly honest," she told him, "I do enjoy having sex. And I don't see any reason why I shouldn't. I think our bodies were meant to be enjoyed. There's no other reason to fuck. Just pleasure, baby, pure pleasure."

"What about babies?" he reminded her with a laugh.

"They're marvelous," she told him. "That's one way to bring more fucking into the world. I'm all for that."

He shook' his head in dismay.

"What's gonna become of you, sis?" he asked her. "I mean, you are too wild. I've heard that you have been having an affair over in high school. That's what the word is."

"He's the star athlete," she told him. "He is tops in his field. I'm tops in my field and we make a pretty good team."

"You're bitching," he laughed. "So you want to ball the top football player in high school because he represents the ultimate. And you figure you're the ultimate pussy."

"Don't you think so, dear?" she asked her brother sincerly.

"I guess you are," he admitted candidly. "I know I've never had a better fuck."

"There you go," she laughed, "you have to agree with me."

Bob finally thought he would confide in her that he was considering going steady with another girl he had met.

"I wanted to tell you about Sandy," he told her frankly. "She and I are considering going steady. What do you think of that, sis!"

"I don't think she's much," Donna said with jealousy.

"She's a good fuck," he told her, "and she's really a nice girl. Warm hearted."

"You're not interested in her heart," Donna shot back. "You're interested in her tight pussy. And from what I've heard she's been had by plenty of guys in school. I must say I don't admire your taste in women, little brother."

"But I like you," he reminded her.

"That's different," Donna insisted. "We are brother and sister. We have a special closeness that you could never have with that girl. She goes with guys just to experiment. If she goes steady with you it will probably be to get another boyfriend back. You know, Dennis dropped her."

"She's dropped him," her brother countered quickly.

"That's not the way I heard it," Donna laughed. "She's pulling your leg."

"I know she's been pulling my cock," he chuckled, "but I never knew she was pulling my leg."

"Your third leg," Donna smiled.

As she looked at her beautiful German Shepherd dog and her brother, she realized what a lucky girl she was.

"What more could any girl ask for?" she smiled happily.

"I guess that's true," he told her. "You've got it made. You've got him and me. Which do you prefer, baby?"

"That, love, is a difficult decision," she teased. "I think Billy's cock is longer. But you know how to use yours better."

Bob didn't know whether to take that seriously or not. He figured his sister had some real strange ideas.
