The next day was nice and the six kids took up the positions that they'd taken the day before. The five oldest ones went through much the same act that they'd gone through the day before and Susan did THINGS to herself till she felt good three times. The older kids never thought of inviting Susan. They would have been shocked if they knew that she was watching them. She was too young. If they thought of it at all it was that maybe in another year she could join in their games.
Dinner went as usual and David went to Susan's bedroom with her to work on math. They started out as they had the night before and Susan was sending the same signals. David started to squirm. He hoped that Susan didn't notice his hard on.
He was starting to notice her as a girl. She was real cute. Her perky little tits in her training bra pushed out the T-shirt she wore, he realized he was staring at them and looked away. He wondered what she looked like without any clothes on. He wished she'd join her sisters at the pond but he had no way of telling her that. He was certain she didn't know anything about all the things that were happening on the farm.
He was trying to make a point about decimal points and realized Susan wasn't paying attention. She was looking at the bulge in his pants. David stuttered and blushed and tried to think of a way of getting out of the room. He stopped trying to explain the math problem to Susan and nonchalantly put a book in his lap. Susan blushed and she looked at his face. She realized that David knew she was looking at his THING so she might as well go a little farther.
"Why is your THING hard, David?"
It had the affect of a body blow. David sputtered and turned beet red. He didn't know how to answer.
"Uh, I can't talk to you about that! It's too embarrassing."
"It embarrasses me too, but I want to know about boys."
That was a stiff left jab. David wanted to know about girls but he was still incapable of responding. Susan blushed as red as David was. She looked anywhere but at David's face. She took a deep breath and looked into his eyes and delivered a right hook.
"I know why your THING got hard at the pond today, but why is IT hard now?"
David's mouth dropped open. Susan had seen what they were doing at the pond. His astonishment loosened his tongue.
"How do you know what we do at the pond?"
"I followed the twins there yesterday. I saw what you and the boys did and I saw what the twins did too. Do you do anything else with the twins?"
"Uh, no. We don't even talk to them about it. We just sort of got started and now we do that every nice day."
Both of them ran out of things they dared to say to each other and sat there blushing. Susan wanted more, she sensed her advantage and bored in with some hard rights and lefts to the body.
"You and the boys played with each other's THINGS and the twins did the same thing, they pushed their fingers in down THERE. I've never played like that with anyone else. Uh, David, if I play with your THING will you push your fingers in my HOLE? I'd like to do that with you, you do it with Ted and John, the twins do it with each other, but I don't have anybody to do it with. I want to do it with you."
Susan realized that she'd finally said what she wanted and breathed a sigh of relief. David wanted to crawl under the rug. There was nothing in the world that he wanted more than to have Susan play with his penis and let him feel her sex organs, but he didn't have the nerve. He just sat there with his mouth hanging open.
Susan wasn't taking no for an answer, she reached over, took the book away, and stroked his penis through his pants. As usual the female of the species was the predator. Her instincts told her she had David reeling in the corner. She had to make use of her advantage. She gathered all her ammunition and followed with a left hook and a right uppercut.
"You let the twins see your THING and you let the boys play with IT, why don't you want me to do the same thing with me? I want to have you to look between my legs and I want you to put your fingers THERE and push them in and out like the twins did with each other today."
Susan had David down for the count. She pulled down his zipper, reached in his pants, and pulled his penis out through his fly. She ran a finger over its head. David watched her hand as it fondled his hard penis. This felt better than anything he'd ever felt in his life. It was better than jerking off, fucking the ewes, thigh fucking with John, or any of the things he'd been doing for the last two weeks. He wanted to pull away but couldn't make himself do it.
Susan was fascinated with the four inch THING she had in her hand. She liked the pink of the head with that cute little slit the drops of STUFF oozed out of. She spread the STUFF over the rest of the head with her thumb each time a drop formed. She traced her finger down vein on the shaft till it disappeared into his fly and traced another back up.
Suddenly Susan realized David didn't have his finger THERE. She let go his THING and pushed her jeans and panties down then unfastened David's belt and lowered his pants so she could see the cute pink sack with the lumps that dangled under his THING. She ran her fingers through his sparse pubic hair and traced another vein back up to the tip of his THING.
David examined between her legs. There were a few strands of pubic hair but they hid nothing. He'd been yards away from the twins at their closest. He'd never been this close to a cunt before now he could get a good look at what was between the outer lips. He wanted to get on his knees and examine it more closely but didn't have the nerve. He saw the outside slit, with little beads of moisture all along it. It was puffed out some and he could see some pink inside.
His hand moved between Susan's legs and he ran his finger along the outer lips of her cunt. It felt real slick and slippery. The slit opened some under his finger pressure and the inner lips were exposed. His finger probed and slipped between the inner lips of her cunt. He felt Susan's hips jerk and pulled his finger away. He was afraid he'd hurt her.
Susan wasn't going to let David get away. "Oh no, David, don't pull away, push your finger all the way into my HOLE. That felt real neat. It felt much better having you do it than when I do IT to myself. Can I do IT to you? What John did to your THING today? Can I make the STUFF shoot out like he did?"
Susan didn't wait for an answer, she started pumping her hand on his penis. David was incapable of answering but he wasn't incapable of putting his finger back into Susan's HOLE. He pushed his finger in and out of that tight, slick HOLE. It didn't seem big enough for a penis to fit into but he knew that was where a penis was supposed to go.
There was a hard bump above the inner lips and David used a finger of the other hand to rub it. The twins always rubbed each other there. His sex books said that it was real sensitive. The book must be right. Susan jerked her hips and squirmed.
David was squirming himself. Susan had grasped his penis very loosely and her pumping was more a tickle than a rub but the friction it caused was more than enough to bring him to a climax. He felt Susan's HOLE contract around his pumping finger and Susan started to moan. She watched very closely as; spurt, spurt, spurt, dribble, dribble, dribble; his STUFF shot out of the slit in the tip of his THING.
Susan looked at the grayish white viscose fluid in her hand. She'd seen the boys licked it off their hands that afternoon. She sniffed, touched it with the tip of her tongue, took a tiny sip, and licked the rest of it up.
David went through the same gyrations. He paid attention to what the twins had done that afternoon. He withdrew his finger from Susan's HOLE, sniffed at it, touched his tongue to his finger, and sucked his finger into his mouth. The two kids looked at each other, blushed, then grinned. They knew they were being very daring.
Susan got the conversation going again. "I don't know how I got the nerve up but I'm glad I did that. I don't want to learn math too quick. You can come up here every night and help me."
David was finally willing to discuss what they had been doing. "Gee, I'm glad you worked up the nerve, I never could have done it in a million years. Uh, I don't know about doing it every night. John might suspect something if we did that. Maybe we could do it twice a week though."
The kids pulled on their pants and continued with the math lesson until bedtime. They didn't say another word about what they had just done. They didn't even discuss the need for secrecy. Each trusted the other not to let anyone know what they were doing. Both were sure this wasn't the last time that they'd do things together.
Neither of them knew where what they were doing was going to lead, but they were willing to let nature take its course. They understood that when they were ready they would go on to something else.
Following the precedent set the previous night David went down to collect John so the could shower and go to sleep.
He made a general announcement to the room at large that he would have to spend a couple evenings a week from now on helping Susan with her math. He basked the praise that his grandparents gave him again but this time he felt a little guilty about it. He would be tutoring Susan in math, of course, and David had every intention of doing that.
However, David knew that math wasn't the only subject they would be studying. Susan and he were going to do some experimental lab work on the subjects covered in his sex textbooks. That was a lot more interesting than the math that they would be doing anyway, and it would probably take a lot more time.
John was surprised that David's penis wasn't hard when they got into the shower. It got hard in short order, however, and they fucked each other's thighs. They went to bed and woke up to jerk each other off.
Ted jerked off twice thinking over the things he'd recently seen. He liked jerking off with David and his brother and he was fascinated with the show that his twin sisters put on.
The twins plotted what they could do to make the shows more interesting. They weren't bored with what was going on they just wanted to make it more exciting. They discussed it while they fingered each other then sixty nined. They hugged and kissed each other while they were recovering.
"Uh, Joan?"
"Yeh?"
"That would be even better if the boys were watching us, don't you think?"
"Uh, yeh. I don't know if I'd have the nerve to do it though."
"We can do it. The boys eat each other's cum and we suck on our fingers after we finger fuck each other. Cunt lapping isn't that much more."
"I guess so. I wonder what the boys will do if we do that?"
"Gees, I don't know. I don't guess they would suck each other's cocks. I'm sure they're not gay. We'll just have to be satisfied with the fun of having them watch us."
By this time the twins had worked themselves up to another sixty nine. They lapped each other's cunts and fell asleep.
Susan lay in bed with a grin a mile wide on her face and fingered herself THERE. That good feeling felt a lot better when David put his finger THERE. It was fun making the STUFF shoot out of that cute little slit in his THING. She liked the taste of his STUFF. She wondered if it would taste the same if she sucked it out of his THING. If she sucked his THING would David lick her down THERE? She gave herself the good feeling twice more, sucked her finger dry, and fell asleep.
