At this mention of the back yard, Judy blushed even redder. "Well, it's none of your business what I did," she said. "Anyhow, how did you know I was gone? What were you doing up at three, for that matter?"
Jimmy's blush almost equalled his sister's. "Aw, I just couldn't sleep. I went for a walk. That's how I know you were in the back yard, 'cause I heard you."
Judy's heart stopped for a second. How much had Jimmy seen? Did he know about her and Grant? Most important, would he tell Kay?
"Jimmy," she said carefully, "I want to know exactly what you saw, and I want you to promise that you won't tell anybody about it."
Jimmy was very puzzled. What in the world was his sister so uptight about? All she'd done, so far as he knew, was walk in the back yard. He was the one who had something to hide. Unless…
Suddenly Jimmy sat up, struck by a crazy idea. If he was making it with Kay, why couldn't Judy be making it with Grant? Boldly he decided to trick her into an admission.
"Okay," he said, grinning wickedly, "I'll tell you what I saw, but I don't promise to keep it a secret. I saw you making out with Uncle Grant."
Judy burst into tears. "Oh, Jimmy, please don't tell Kay. Please, Grant would be furious, he wouldn't have anything more to do with me. He'd think I finked on him. Please, Jimmy."
"Hey, keep cool," said Jimmy, hurrying over to hug her. "I was just kidding. I wouldn't tell on you. But, golly, Judy, is it really true? I mean, were you really making out with Grant?"
Judy glared at him. "You liar. You tricked me into saying that. That was really mean, Jimmy."
"I'm sorry," said Jimmy. "Honest I am. I was just curious. I'd like to hear all about it. How far did you go?"
"I'm not going to tell you another thing," said Judy, pouting. "You tricked me, and now I don't trust you. You'd probably tell Kay everything."
"No, scout's honor," said Jimmy. "I promise I won't tell Kay anything. And, look, Judy, to show you I really mean it, I'll tell you a secret, too. Only you have to promise not to tell Grant."
"I'll promise," said Judy, "if it's a good enough secret."
"Well," Jimmy said, looking very smug. "I fucked Kay last night."
"You WHAT?" Judy stared at him, goggle-eyed. "I don't believe it. When?"
"Just before you and Grant came outside. We were in the bushes, doing it. You almost stepped on us. That's how I know you were there."
Judy was convinced. "Golly, that's really something. You actually made it with her? What was it like?"
"Far out," said Jimmy with a big sigh. "Fucking is really the greatest. But do you promise not to tell Grant, if I promise not to tell Kay about you?"
"Sure," said Judy, "that's fair enough."
"Okay," Jimmy said eagerly, "now tell me what you did with Grant."
"Well," Judy giggled, "he didn't want to very badly, but I got him to fuck me."
"Wow," said Jimmy. "How come he didn't want to?"
"Oh, he was just uptight about it," said Judy. "He was scared Kay would find out."
"Yeah, she was pretty uptight, too," said Jimmy. "It took a lot of work to change her mind. Grownups can really be silly about some things."
"You better believe it," said Judy.
They sat grinning at each other. Finally Jimmy, said, "Well, so we both scored. That's really something. I think we oughta celebrate."
"Right," said Judy. "How?"
"Well, grownups usually celebrate with a drink," said Jimmy. "Let's cop a couple of beers."
"Oh, Jimmy, I don't know," said his sister. "Grant and Kay would be mad if they found out."
"Let 'em be mad," Jimmy said. "I figure we can do just about anything we want to from now on. I mean, we've got the goods on them. All we have to do is threaten to fink. Grant doesn't want Kay to know about you and him, and vice-versa. See what I mean?"
"Yeah," said Judy, "you're right. Oh, boy, we can get away with just about anything now, like you said."
"So let's start with the beer," said Jimmy.
The twins had never tasted alcohol before, and one beer apiece was sufficient to make them giggly and high. They sat on the edge of the pool, kicking water on each other and feeling very frisky.
"Let's skinny dip," said Judy, hiccuping.
"Good idea," said Jimmy, getting to his feet and wobbling around. "Shit, I think I'm drunk."
"Me, too," said Judy. She started giggling and couldn't stop.
Staggering and stumbling, the young brother and sister got out of their clothes. Jimmy charged at Judy, intending to push her into the pool, but she side-stepped just in time, and he went crashing into the water.
"Damnit," he said, popping to the surface and sputtering, "you'll pay for that."
Judy gave a shrill scream as Jimmy grabbed her ankle and pulled her into the water. A furious water fight started, and brother and sister doused each other till they ran out of breath.
"Gee, this is great," said Judy. "It feels so good to swim without your bathing suit."
"Right," said Jimmy. "I think I'll just tell Grant and Kay that we're not gonna wear suits any more. Whether they like it or not."
"They'll have to like it," said Judy. "They won't have any choice."
Jimmy was staring rather fixedly at her chest. "Hey, you know something," he said, "I never realized you'd grown tits."
"Well, for heaven's sake," said Judy, "I've been growing them for a whole year now. You're not very observant."
"Well, it's just that they're so small," he said. "You hardly notice them. I mean, they're not like those big boobs Kay has."
Judy flushed angrily. "I suppose size is all you think about. As a matter of fact, I think Kay looks like a cow, and I hope my tits never get as big as hers. They look awful, and they must weigh a ton."
"Yeah," sighed Jimmy, "they're pretty heavy, all right. But I think they're beautiful."
"Prettier than mine?" said Judy, in a hurt tone.
Her brother relented. "Aw, now, I mean, you've both got pretty tits. They're just different, that's all. Hers are huge, and yours are, uh, uh…"
"Puny," said Judy, bursting into tears. "That's what you meant to say, wasn't it?"
"Aw, Judy, don't cry," said Jimmy. He paddled closer to her and reached out to cup her tiny pointed breasts. He squeezed them affectionately and rubbed the pretty pink nipples with his thumbs. "I think they're real nice," he said. As a matter of fact, the more he looked at them, the prettier they seemed.
"Gee, Jimmy," said his sister, "that feels nice. Don't stop."
"Well, it's kinda hard to play with your tits and stay afloat at the same time," said Jimmy.
"Then let's go lie on the towel," Judy said.
Judy stretched out on the beach towel, and Jimmy lay down next to her. A passer-by would easily have guessed that they were twins. Both had slim, gleaming, freckled bodies and bright red hair, the only difference being that Jimmy's hair came to the nape of his neck, while Judy's fell almost to her waist.
Judy sighed happily and said, "Okay, go ahead, play with my tits."
Jimmy eagerly reached out and cupped the tiny melons again, squeezing them gently in his hands. They really were cute little jugs, he decided, although it wasn't as exciting as when he'd fondled Kay's huge tits. "Are they gonna get any bigger?" he said.
"Oh, yes," said Judy. "They're just starting to grow." She flushed slightly and sighed as her brother rubbed her sensitive clover-pink nipples. "Did you play with Kay's tits?"
"Oh, boy, did I," said Jimmy. "You wouldn't believe how big they are."
Judy ignored the reference to size, which only made her jealous. "Show me some of the things you did," she said.
Jimmy was more than willing. He bent low over her and flicked out his gleaming red tongue to lash her pretty pink nipples. He swished his tongue all around them, making Judy shiver and sigh. Under his fast, slick licking, her tiny nipples grew stiff and pointed with arousal. Every hot touch of his tongue sent jolts of pleasure straight from her nipples to her creaming little cunt.
