Robert Jenkins: Seducing Mom and Dad

Dot blushed. Jack swallowed hard.

"Uh… yeah… went down by those big rocks," he mumbled.

"It must be really hot there… out of the wind," Emma continued. "You're bath all hot and sweaty. Maybe you should jump in the water and cool off."

"Oh, yeah… sure," Jack said.

Happy to get away, he sprinted for the water. He sensed Emma and Dot following. He thought he heard Emma say in a low voice to Dot, "I'd like to have a little talk with you…" But he closed it off by diving into the first wave. The water closed over his head, hiding him.

Jack swam hard. He glanced back once and saw Dot and Emma far behind him. Emma was doing all the talking at first, Dot hanging her head. Then he saw Dot's face tighten. She began to talk back, obviously defending herself. Let them argue, he thought with relief. It might lift some of the pressure from him.

Jack circled around the two hotly arguing sisters. When he got back to the blanket, Sue was still there. He dropped down next to her and took a big gulp from the water bottle. The girl smiled at him shyly, not completely understanding what had been going on.

Jack's eyes slowly widened. This was the first time he'd had a chance to take a really good look at Sue since she'd taken her shorts off. She was totally naked now. She was smaller than he'd thought, beautifully formed. Jesus, those tits! The most perfect he'd ever seen!

Then his eyes slipped lower down the blushing girl's body. What a cunt! Somewhere in between Emma's and Dot's. Broad and soft-looking but also tender and delicate. There was something about Sue's sweet snatch that told Jack it had never been used. No cock had ever slipped up into that inviting little nest. What a shame.

Jack's eyes narrowed. By God, he'd see if he couldn't do something about that!

Arguing in the surf with Emma, Dot finally made her most telling point. Emma had just accused her of trying to steal her boy friend, Jack.

"I guess it was just all a bunch of hot air, then, Emma, when you told us you believed in freedom," Dot said bitterly. "That one person never owned another person's crotch. Didn't you write me a letter once saying that you fuck other men beside Jack?"

Emma was left spluttering. "Well… but it's kind of different when your own sister…"

"And didn't you say once that friends should be free with one another sexually? Don't you feel friendly toward the members of your own family?"

Emma swallowed hard. What more could she say? She was caught in a neat trap of her own making. If she continued to show her anger over Dot and Jack fucking each other, she would look like a hypocrite. Yet, to her own surprise, she was indeed jealous. Oh, she had no doubt Jack had fucked a few other girls since they had started going together, but never almost in front of her like this. And certainly with no one as close to her as her own sister!

But she had no choice but to shut up. She made a big effort to be pleasant to Jack when she and Dot joined him and Sue on the blanket. But she maneuvered herself so that she was always between Jack and Sue. She'd at least make sure her baby sister wasn't debauched.

Later, when skins started to redden under the hot sun, Jack took the girls back to Emma's place. He knew he was walking on thin ice with Emma, so he left soon after, leaving the three sisters alone.

Dot, sensing Emma's helpless position, teased her sister a little. "You've really got something there, Emma," she said.

Emma unfortunately took the bait. "Oh… you like that big cock of his, do you?" she bridled. Then she remembered Sue was still in the room. She turned, to see the girl's eyes big and staring.

"What are you two talking about?" Sue asked. She looked back and forth between Dot and Emma. Then realization came. "Oh!" she exclaimed. "When Dot and Jack went off together… they… they…" The young brunette blushed, clear down to the roots of her hair.

"Now look what you've done!" Emma snapped to Dot. "You've upset Sue."

Rut Sue surprised her oldest sister. Her lovely young face suddenly grew angry. "Would you stop treating me like a child!" she wailed.

Emma looked thoughtfully at her youngest sister. "Well… if you were brought up the same way I was, it's probably true. Mom never told me a thing. Too embarrassed, I guess."

"Same with me," Dot said eagerly. "I had to pick up everything I learned from my friends," she giggled. "Some of them sure knew a lot."

Emma began to grow interested. Maybe it was time to start acting like a big sister. "Just what do you know, anyhow?" she asked Sue.

Sue blushed again. "Well… I know a guy sticks his thing… prick up inside a girl's… pussy and that he makes her all sticky inside. That's what my friend Lois told me a guy did to her." The girl wrinkled her nose. "Sounds messy."

"Well, it is, kind of," Emma admitted. "The guy shoots his semen up into your vagina," she said, using all the correctly polite words. "But I don't usually notice, because by then I start to cum, too."

"Cum?" Sue asked, puzzled. "What's that?"

Emma raised her eyebrows. "When you get it off." She saw Sue was still puzzled, then remembered Sue'd never made it with anybody. She had an inspiration. "You know, the way you kind of… explode when you masturbate."

Sue was even more surprised. "Masturbate?"

Emma knew she had to get a little less clinical. "You know, when you play with your clit… stick your finger up your pussy."

Sue looked horrified. "Oh, I'd never do a thing like that! Mom told me it was wrong. That it would make me grow up weird."

"Oh, for God's sake! What kind of bullshit is that?" Emma burst out, slapping her palm against her forehead. "I've been masturbating ever since I can remember, and I didn't grow up weird, did I?"

"You just don't know how it's been at home the last couple of years," Dot cut in. "Something's wrong between Mom and Dad. They've grown so uptight. The atmosphere around the house is like a morgue. That's why I was so horny," she burst out. "They watch us like hawks. I hadn't been laid in so long!"

Emma was upset. "Sounds terrible," she said. "It's a wonder they ever let you go to the beach with me."

"Oh, they trust you," Dot said. "You know how you were always the brain in the family."

Emma felt a twinge of guilt that she might be betraying her parents' trust. But then she rallied, realizing there was no one else to help her sisters out but herself. She could see from the confused look on Sue's face that the girl was bursting with sexual curiosity. Better to get it from her big sister than some guy on the street.

"Maybe you'd better learn about the birds and the bees," Emma told the girl. "What would you like to learn first?"

"Well," Sue said hesitantly. "I… I'd kind of like to learn more about masturbating and cuming. You say it won't hurt you?"

"Hell, no. Sometimes it keeps you from going out of your mind."

Emma tried to formulate a way to tell her sister how to finger-fuck herself. Or tickle her clit, which was her own favorite way. She suddenly decided to show Sue. The truth was, the conversation was turning her on a little. And Dot's being fucked by Jack made her realize how much she herself needed a cum.

"Okay… everybody take off their clothes," she ordered, pulling her shirt over her head.

Sue hesitated shyly, but Dot started peeling off her clothes with a big grin. Sue, afraid like most teen-agers of being left out, finally joined the other two girls in stripping.

Emma stared at her little sister's gorgeous body. At the beach she'd been too concerned about Jack and Dot to pay much attention. Sue's perfect tits amazed her, and made her a little jealous. When she stared at the girl's virginal cunt, a funny feeling fluttered around in her stomach.
