An angry Chrissy reflected on how she was fifteen years old and she hadn't been on a single date.

It wasn't because she was unpopular. Lots of kids at her school liked her and wanted to be around her.

It wasn't because she was ugly. Her 5" 6" frame supported breasts that were a handful each, tipped with sharp little pencil eraser sized nipples just made to suck on. Below that were her thin waist and hips that any baby-bearing woman would love to have. Her cute little pussy lips were pink and plump and nestled just below fine wisps of golden pubic hair. Her face was gorgeous. She was a knockout.

No, the reason Chrissy had never been on a date was because of her father, one John Robinson by name.

He wasn't mean or anything. He just remembered what he tried to do with fifteen-year-old girls when he was, say thirteen through nineteen. For that matter he lusted after Chrissy's friends regularly and would gladly plow their sweet teen furrows if it didn't mean he'd end up in prison. He knew what boys thought about when they looked at his daughter, and he had decided a long time ago that she wasn't going to be exposed to groping strangers out for a quick fuck and then on to the next girl.

To be fair, any boy she wanted to spend time with was welcome to come to the house and they could watch TV, or make something to eat, or play board games on the dining room table. Anything except be alone, especially in a bedroom.

Adding to the problem was Chrissy's brother Bobby. He was seventeen and a tackle on the football team. He was a big, big boy and nobody wanted to mess with him. He made it known when Chrissy was just a freshman that any guy who messed with his sister sexually was dead meat. Period. He was encouraged in this attitude by his father. Chrissy had no mother to intercede for her. Her mother had run off with a biker gang when Chrissy was only three.

The end result of all this "protection" by her father was that he had erred in his judgment - seriously erred.

For, you see, Chrissy had no experience with groping boys at all. She'd never been kissed, never been petted and for sure had never had a boy's mouth or fingers anywhere near her sweet little pussy. No boy even tried to sneak off to a dark corner with her. They danced with her - properly apart from her soft body, of course. But they never tried to get in her panties. And, because of this, she just flat didn't believe that boys really tried to do any of those things. As far as she was concerned, it was all a big fairy tale her father had concocted just to justify his stupid rules.

She had just told him that, in fact. She had told him in a loud voice that some might even have called a scream. Her face was red, and her delightful bosom was heaving. Her father was sitting in his lounger with a smug look on his face. He knew what boys tried to do.

"Chrissy, darling," he said calmly. "I know what boys want to do to you, because I was a boy once upon a time and I tried all the things that boys always try with girls. I tried the lines, I tried getting them drunk, I tried begging for sympathy - all of it. And I got my John Thomas wet plenty, I'll tell you that!" He jerked his head, somewhat startled that he'd admitted that to his nubile teenage daughter.

"Oh bullshit!" Chrissy yelled. "Just bullshit, Daddy. Boys don't want those things anymore. Maybe they did when you were young, but boys are polite nowadays, since women's lib and all that stuff. You're old fashioned Daddy and it's not fair. I don't get to do anything!" she wailed.

John frowned. "Chrissy!" he barked. "That will be enough of that kind of language. I'm not wrong about this and I think I can prove it."

"Oh reeaaallly," Chrissy drawled. "I'd like to see that, Daddy. I really would."

John thought for a minute. "All right. But you have to do whatever I say, okay?"

Chrissy was puzzled. She always did what her father told her to. "What do you mean?" she asked warily.

"I think I can prove to you what boys want, and what that causes girls to want, but you'll have to do some things that you might not otherwise be willing to do," he said, like that explained everything. "Look," he said impatiently. "Do you trust me?"

"Of course I do, Daddy," she said.

"Okay, then, just keep on trusting me, even if it seems weird, okay?"

"Okay, Daddy," she said.

"Robert!" yelled her father.

A distant call came back "What?"

"Come down here!" yelled her father.

A moment later Bobby, came bounding down the stairs. He was dressed in the usual, sweat shorts and a tank top.

"What's up Pops?" he said. He nodded to Chrissy.

"I need you to do something for me," he said. "I want you to tell Chrissy ... I mean us, what goes through a boy's mind when he's on a date with a girl he likes."

"Um ... I don't understand," said Bobby.

This wasn't technically true. Bobby pretty well knew what he thought about every girl he took out. He hoped each one would turn out to be a cumslut who would spread her legs for him without asking. Why else would a guy take a girl out? But he didn't think that's what his father wanted to hear. And, since he didn't know the right answer to the question at hand, he played the ignorance card.

"Chrissy doesn't believe that boys she goes out with would actually want to have sex with her," said John.

Two things happened almost instantly for Bobby. First, all the times Bobby had tried to peek at his sister, to see her naked, and all the times he had furiously beat his meat while thinking about her naked, flashed through his mind. He knew how desirable she was as a woman. And he was her brother!

Second, he couldn't help but reflect on the mental image that came to his mind concerning the concept of "boys wanting to have sex with Chrissy". In this case, the last boy Bobby had seen Chrissy with came to mind. That was Rex Johnson, who bragged about what a fabulous cocksman he was. The fact that Rex was only with Chrissy because she stopped to help him pick up some spilled papers didn't come into play.

What Bobby visualized was Rex, hunched between Chrissy's wide spread legs, while his ass bobbed up and down and his undoubtedly nasty cock slithered in and out between his sweet sister's pussy lips.

In short, Bobby got horny and pissed at the same time. He laughed a dark laugh.

"That's stupid," he said. "Every guy who ever looked at you wanted to get in your pants."

"That's not true!" squealed Chrissy, her eyes wide at how crude Bobby could be.

"That's what we're trying to tell you, honey," said her father in his reasonable voice. "Men are built to want to have sex with beautiful girls. You are a beautiful girl. Ergo, men want to have sex with you. Boys too," he added.

Chrissy didn't believe it for one minute. She had an idea. "All men?" she said, acting like she might believe it.

"All men!" said her brother and father together.

"So..." she preened. "You have wanted to have sex with me too?" She clasped her hands behind her butt and grinned at her father. "I mean you are a man, right? And you did say all men," she finished triumphantly.

She turned on her brother. "And you too!" she giggled now. "Obviously you too have been practically consumed with lust for your dear sister." Now she laughed out loud.

Then she stopped.

Neither man was laughing with her. In fact, both looked decidedly guilty!

"You'll never believe me until you see it for yourself," said her father. "So, you and Bobby are going on a date. Tonight. And I'll be with you, but I won't say anything, unless you two are supposed to do something and I see you aren't doing it. Okay? It will be a pretend date, but Bobby will show you what boys do on dates with girls. Then you'll understand," he said with finality in his voice.

"But Bobby's my brother!" said Chrissy.

"And Chrissy's my sister," said Bobby, somewhat unnecessarily.

"That's right, and that's the only reason I'm allowing this," said John. "You must be made to understand how dangerous it is out there. Now. Both of you. Go get dressed for your date. Each of you choose something you'd like to wear on a date with someone you really like."

Both teens trudged off muttering about stupid ideas. John went to each room to ensure that his orders were followed. He went to Bobby's room first. "Bobby, I want you to pretend she's just another girl you met at school. Treat her just exactly like you'd treat any other girl. Okay?"

"Sure Dad," said Bobby, while mentally saying, "With you watching ... right."

Then John went to Chrissy's room. He walked in to find her dressed only in her panties.

"Daddy!" she yipped and covered her precious breasts with her dainty hands.

"Oh! Sorry, pumpkin," he said, looking at the floor. "I know Bobby is your brother, but I want you to pretend he's some boy you wish I'd let you go out with. And dress like you were going out with that boy, not Bobby." Then he left, before she could see the tent in his pants. While that might have supported his contention about "all" men, he was a little embarrassed about it right then.

Bobby got back to the living room first. He had on his team sweats. They were talking about football when Chrissy started down the stairs. Both men looked up and their jaws dropped. Chrissy was dressed in a micro skirt with a matching halter top. The halter top had a deep vee that dropped well below the mid point of her breasts, ensuring that everyone knew no bra of any kind was involved in this outfit. Sandals completed her ensemble.

Quite suddenly Bobby didn't have very much trouble at all pretending this was just some girl he was taking out on a date.

"Wow," he said. "You look hot!" He flinched and looked at his father out of the side of his eyes, but his dad was staring at Chrissy too.

"Yeah," said John in a dull voice. Then he shook his head, as if trying to drive some thought out of it. "Okay, now you guys have already had dinner. Where would you take her now, Bobby?"

Bobby knew he'd try to get his date out at the lake, where it was quiet and remote and romantic. But he couldn't say that in front of his dad. "I'd uh drive around. I guess."

"Okay then," said John. "Let's go." They went out and got in the car. Chrissy and Bobby in the front, and John in the back seat. Bobby started driving. He didn't know where to go since he couldn't go to the lake. He was getting frustrated. He could be out with a real girl tonight, but he was stuck with his sister. He glanced at her. Her micro showed her legs almost clear to her pussy. He gulped. She scooted over and leaned one hot breast against his arm. It felt soft.

"Aren't I supposed to sit here, beside you?" she asked in her sweet voice.

"Uh, yeah ... sure," he said. This was crazy. They'd be out here for hours. He decided to call his father's bluff. "Actually, I'd be taking my date out to the lake. There's this cool place where I take the girls. You know, to talk ... and stuff."

"Now that's more like it," said John. "Let's go."

Bobby thought about what was happening as he drove. He'd tried to call his father's bluff, but his dad seemed to be pushing them toward something he'd dreamed about occasionally as he beat off. That was petting his sister and getting to see her naked. He felt his prick begin to fill with blood. Who knew what might happen? He'd just ride along and see. They got to his favorite spot and he parked, turning off the lights. He already had the radio on and he got out his favorite make-out CD and put it in the player. He sat there, not knowing what to do.

"See? This isn't so bad, Daddy," said Chrissy. "I still don't understand what all the fuss is about."

John leaned forward from the darkness in the back seat. "Bobby, is that all you do when you bring a girl out here? You just sit?"

"Well no," said Bobby. "I usually try to..." He dropped off. He didn't want to admit that he usually tried to get into the girl's panties.

"What do you try to do Bobby?" said his dad. "Come on. Chrissy needs to know."

"Well I kiss them ... and touch them..." He didn't add, "if they'll let me."

"Okay then, get to it. Show her what boys do."

Bobby couldn't cope with the stress. He was trying to be two people at the same time.

About then Chrissy tipped her head up and whispered in his ear, "Aren't you going to kiss me Bobby?" She was trying to call someone's bluff too.

So Bobby kissed her. In his confusion, he kissed her like he'd kiss any girl. Definitely not like he'd kiss his sister. But she felt like a girl, and she smelled like a girl and within fifteen seconds she was kissing like she'd done it plenty of times.

As for Chrissy, when her brother kissed her like that, like they did in the movies, she felt weak all over. It made her feel funny in her stomach. No, not in her stomach, but down there somewhere. She decided she liked this kissing stuff. When she felt his tongue slip into her mouth, all slippery and smooth, the feeling "down there" got more intense.

When she kissed him back, and gave him some tongue in return for his own, Bobby went on autopilot. His hands began to stroke her back, moving to her arms, caressing her hair. Now he kissed her cheeks and neck, nibbling on her ear lobe. She shuddered, a good sign, and he kissed her again as he decided to see what her young breasts felt like.

When Bobby's hand came around her elbow and cupped her breast through the halter top, Chrissy almost stopped breathing. What was he doing? Boys weren't supposed to do that. She broke the kiss. "Bobby!" she said.

"Aw, c'mon. I won't hurt you. You just look so hot and you feel so soft."

He went back to kissing her.

Chrissy felt all muzzy inside. She felt a thrill shoot through her when he said she looked hot. And his kisses were so wonderful. What could it hurt to let him feel her boobs a little? When his hand slid over her breast again, she pressed it into his hand. It did feel good. She was enjoying a kiss when she realized his fingers were pinching and rubbing her nipple. And that felt really good. Then, somehow, his hand slipped inside her halter top and now he was fondling her naked breast. Now he thrummed her nipple. She felt a sharp stab of pleasure between her legs. She thought that was very odd, but if felt good too.

"Chrissy?" he said as they paused to breathe.

"Hmm?" she said back.

"Can I see em?"

She knew exactly what he was talking about, because his hand was still there, still squeezing and roving around her breast. He'd gotten in through the side of the halter top. But she wanted to tease him for some reason.

"See what Bobby?" She arched her chest, pushing the breast into his hand.

"I want to see your titties," he said. "I bet they're beautiful."

"You've seen my boobs before, you ninny," she giggled. "Remember that time when I was in the shower and you had to pee so bad and you couldn't wait and you barged in? You saw 'em then."
