They hurried into their clothes, got behind the trees, and waited. In minutes the girls appeared. They followed the example the boys had set and didn't turn away from the boys as they undressed. The boys watched them remove their bras then their panties. Joan used both hands and separated the outer lips of her cunt as she remained facing the boys' hiding place. The boys were pretty far away but they could see the inner lips of Joan's cunt and what looked like a little bump at the top of them.
David's sex books said that those inner lips were the entrance to a girl's vulva where you pushed your penis when you fucked a girl and the bump on top was called a clitoris. Alice spread her cunt lips too, and the girls stayed in that position long enough for the boys to get a good look. It was worth letting the girls see them jerk off just to get this better view of their cunts. The books had illustrations but a real live cunt was better.
The girls followed the boys lead. They faced the boys, held the lips of their cunts apart as far as they could, stroked along the outer lips few times, then went for a short swim. They didn't stay in the water any longer than the boys had, only long enough to decide how to respond to the boys' show. They and came out of the pond for the important part of the agenda.
The boys were wide eyed. Each held the other's cock and watched to see what the girls would do. They hoped that the girls would finger fuck themselves. After all that was the equivalent of the boys jerking off. They didn't think they could get to see more of the insides of their cunts but they might. By this time both boys were sporting hard penises again.
Joan pushed two fingers between the inner lips where a penis was supposed to go and pumped her fingers in and out. Alice held her cunt lips open with the fingers of one hand and rubbed her clit with the other. Each boy pumped on his partner's penis.
The girls heard the movement in the bushes and it excited them even more to think that the boys might be jerking off again. They closed their eyes and thought of the boys jerking themselves off. They were sure the boys were doing it again while they watched them finger fucked themselves. They switched what they were doing and moved their hands faster and faster.
The boys watched the show and fucked each other's fist faster and faster. The girls hips jerked and the boys heard them moan just about the same time that the cum erupted from their penises. They licked the cum off their hands and watched the girls dress. David wondered how much more interesting things could get. They were getting more interesting every day.
That night at bedtime the girls discussed that very thing. The girls each had a finger in the other's cunt and would wiggle it every now and then.
"Wow! It was neat seeing the boys shoot off."
"Gees, yeh. I wonder what else we can do to get them to do?"
"I don't know. David sure is giving John more courage than he had before."
"Maybe they're giving it to each other. We go first tomorrow, can you think of anything we can do to get them to go even further?"
"What if we finger fuck each other then see what they do?"
"That's a good idea. We'll try it. I'd really like to have one of them finger fuck me and I'd love to play with their penises. It'd neat to find out what a boy's penis feels like. It would be fun to make that stuff shoot out of the end of their penises. That would be awesome!"
"It sure would! Wow!"
The fingering hadn't cooled the girls off and the discussion heated them up. Joan moved in to lap Alice's cunt. When Alice couldn't take any more she pushed Joan's head away, rested while she caught her breath, and traded positions with her twin sister. She lapped Joan's cunt until Joan had to push her head away. The girls cuddled and kissed for a while before they went to sleep.
The boys would have been very interested in the conversation and the action that went on in the girls' room. The girls would have been just as interested in what went on in the boys' room. The situation there was just as charged. Their minds were running along the same lines as the girls' minds were.
A lot of time and trouble could have been saved if the four of them could get together and talk it over, but at that point in time neither the boys nor the girls could have done it. It would take a little more give and take as well as a lot more exhibitions before they would be ready to progress to what all of them wanted to do in the first place. The boys sat at the head of the bed and gently stroked each other's penises.
"Uh, David?"
"Yeh?"
"Can you think of anything else we might do if the weather is good tomorrow?"
"Gees, no. Can you?"
"What do you think the girls would do if we jerked each other off where they could see."
"They might think we were gay."
"Why would we be watching them then."
"Want to try it next time? It's their turn to go first. We could jerk each other off. That would give them a lot of time to figure out what they could do. I don't know what they could come up with but I sure do want to find out."
"Maybe they'll finger fuck each other while we're watching."
"Yeh, that would sort of be the same thing we're talking about doing. That would be neat! Maybe they can think of something even better but, like you, I don't know what it could be."
"Uh, I wish one of them would jerk me off while I played with her cunt. I could get a better idea of what it's like inside a girls cunt. It would be fun to make them jerk their hips like they did today. That would be even neater, but I don't think I'd have the nerve."
The boys' cock stroking had been getting more and more frequent during this exchange. They applied themselves to giving each other a good jerk off. The spit on their hands and went to work. The teased each other's sensitive spots and tickled each other's assholes.
Each of them did everything they knew the other liked best. Each was pressing the others' asshole with a finger tip and pumping as fast as they could by the time they both shot off. They were panting by the time they each gathered a handful of the other's cum and licked their hands clean. The boys held each other in their arms for a while before they went to sleep.
The girls were sleeping with their arms around each other. Alice wiggled a little, and woke up. She pushed a hand into Joan's pajama bottoms and a finger into her cunt. Joan wiggled a little to get the feel of what was going on and woke up. She pushed Alice's pajama bottoms off then her own. She moved around into a sixty nine.
June pushed her face between Alice's thighs. Alice did the same thing between Joan's thighs. Alice licked Joan's inner cunt lips and tickled her ass with a finger. Joan sucked on Alice's clit and tickled her ass. Neither of them was in a hurry. Each of the girls moved her attention from point to point on the other's body. Alice tickled Joan's inner thighs with the tip of her tongue where she knew Joan was ticklish. Joan used the same ploy on Alice and got her to wiggle.
Alice pushed her tongue as far as it would go into the inner lips of Joan's cunt and flicked it in and out. Joan captured Alice's clit between her teeth and massaged it with the tip of her tongue. Both the girls reached their limit. Their cunts were contracting and their hips were twitching. They pulled away from each other and they hugged and kissed again before they fell asleep.
David woke up with John's hard penis lodged between his thighs. It had felt real good last night when they'd sort of jerked each other off with their thighs instead of their hands. He liked to feel John's penis there. He gathered a gob of spit in his hand and, being careful not to wake John up, spread it right under his balls and squeezed his thighs tight around John's penis. He slowly moved his top leg back and forth over his uncle's hard penis. John mumbled and wiggled his hips.
