They kept going like that for a while, until they both started to orgasm. It seemed the shuddering and climaxing would never end. Had someone walked in then, neither girl would have noticed or cared. Actually, it was fair odds that someone could come in at any time. The danger of being caught only made them that much more horny, when they took the time to remember where they were.

Finally, both were too tired to go on, and took a break. They sat underneath the water as it poured from the showers and regained their strength.

"Are you keeping track of time?" Katherine asked. She lazily ran her hands over Heather's slick, bronzed skin. She added with a smile, "I guess being forced to have sex with you isn't such a bad thing, after all."

"The only thing I'm wearing is my watch," replied Heather. "We've got lots of time... By the way, for such a stuck-up prude, you can lick and finger pretty well. You seem to have some experience with women. I had you figured all wrong. And such enthusiasm! I was rather looking forward to really forcing you, but this is just as fun, if not better."

"Well, you're nice!" replied Katherine sarcastically. "My only experience with this is with Kim in the last week. And you, for such a stuck up bitch, I have to admit you're pretty hot."
Heather let the "stuck up bitch" comment slide, since they were so intimate at the moment.

Katherine went on, "And not too shy with women either. To think you've been watching us cheerleaders practice every day - I can only wonder what you've been thinking. Whatever would your boyfriend, the star quarterback, have to say?"

"He'd get all hot and bothered if he could see us." She began to caress Katherine's wet and glistening shoulders and boobs as if to emphasize the point. She started to soap her again since the soap had mostly washed away. "But that prick isn't going to get so lucky. I just do him for the status. I've got a couple of other pricks on the side which are much more filling and tasty."

They began to kiss, lick and finger each other all over again. Their hands slipped and sled all over their bodies. Heather generally took the lead, since she was much more experienced in Sapphic lovemaking. Katherine leaned up against the wall of the shower while Heather got on her knees behind and ate her out as the water ran down all over them.

"Wait," said Heather suddenly. "I almost forgot!" She got up, ran to her locker and dripped water all the way. She came back with a black dildo that wasn't too thick, but was at least a foot long. It was handheld and not of the strap-on type.

"Mr. Excitement!" she said. "It's even got batteries." She turned it on, and it began to shake and even rotate. "I hope we don't get electrocuted," she giggled.

She walked towards Katherine with it. "Are you ready for this throbbing monster?"

"Wait!" said Katherine. "I'm still a virgin! I don't want my first time to be with Mr. Excitement!"

"I still don't feel a hymen," Heather said skeptically as she probed deep inside Katherine's pussy with her fingers.

"I am! You know how prudish I was before last week. But now I'm getting all slutty, and I don't think I'll be one much longer. Next time we do it, I'll be happy to feel Mr. Excitement, but for now let me do it to you."

Heather could hardly object to that. "Get me off!" she cried. She turned off the water, leaned up against the wall, and thrust her ass out.

Katherine held Mr. Excitement in her hand, but she hesitated, happy just to soak in the view.

Katherine was staggered with Heather's beauty. The head cheerleader's perfect butt was raised high in the air, and bent higher and higher as Heather wriggled in anticipation for the dildo to come. A deep tan covered every inch of Heather's privates. It made her naturally blonde bush stand out in contrast all the more.

As if that wasn't enticing enough, Katherine loved the way the water from the recently turned-off shower head continued to roll down Heather's skin. Mesmerized, she watched the water roll down Heather's back, ass, and legs, and fall to the floor.

"What's taking you so long?" Heather asked, a little bit irked.

"Just admiring the view. Sorry. ... And I can't believe this is happening right here in the locker room."

Katherine snapped out of her reverie and put Mr. Excitement in all the way. Then she stuck a finger in Heather's anus and began to finger her there, even as she reached around and began to grope Heather's dangling boobs and pinched her nipples. From the surprised and happy sounds Heather made, it seemed the anal finger was a new experience even for the very experienced head cheerleader.

The two went on like that for some time, until both of them were nearly completely dry from their showers. They could have kept it up for much longer, but their fun came to a sudden halt when they heard the door leading from outside to the girl's locker room open.

They both froze. It took a few seconds for someone to walk farther into to locker before they could turn and walk down a hallway and into the showers, but that's exactly what they heard someone doing.

Katherine thought, Shit! Caught again! Twice in one day.

CHAPTER 4

As they separated from each other and tried to stand up, they heard a voice, "Heather? Katherine?"

It was Amy. She turned a corner and saw them both naked in the showers as they tried and failed to act casual. Her eyes opened wide.

"Hi Amy!" they said simultaneously, both faking enthusiasm to see her.

"Hi! There you are!" Amy said happily and casually - she didn't stay surprised for long. "I heard the water running. Janice sent me to see what was taking you." She frowned, quizzically. "But why are you two taking showers in the middle of class? ... And Heather! What's that thing sticking out of you?!?" She pointed towards Heather's pussy.

"Oh shit!" both Katherine and Heather involuntarily said at once. A good six inches of the big black dildo stuck out of Heather's pussy and into the air.

For once in her life, Heather felt totally ashamed. Especially when she realized just how liberally her pussy juices flowed off of the dildo. For a moment, she thought she was totally ruined, and lamely attempted to cover herself. Heather had done a lot of wild things, but she'd never been caught.

Katherine quickly sidled up to Heather's ear and whispered, "Don't worry; you know how Amy is so clueless and malleable. Let me handle this. Just follow my lead."

"Amy!" Katherine said out loud in a casual voice. "That's a good question! Why don't you come over here and I'll explain all about it." She had no idea what she would say, but she was stalling for time.

"M'kay!" said a happy and completely unsuspicious Amy. "But wait. It's wet over there. And what about practice?"

"Don't worry about practice. After all, Heather is head cheerleader and she says this is an important part of your practice too, right Heather?"

"Right," said Heather uncertainly, still recovering from being caught.

"We're just practicing some different kind of stuff. So just take off your clothes and come over here. You probably could use a shower anyway."

Amy began to take her clothes off. "Yeah, Janice is making us all sweaty." She shucked off her clothes so enthusiastically that it seemed as if it was a crime for her to ever wear clothing in the first place.

As Amy took off her clothes, Katherine whispered again in Heather's ear, "Let's have a little fun with Amy, but not too much, okay? Follow my lead."

Heather just nodded dumbly in reply as she watched Amy strip. She was blown away by the situation - she prided herself on never getting caught and didn't even know what to do if she was caught. She was so wrapped up in the situation that she'd completely forgotten about the dildo which still obscenely protruded out of her pussy.

Amy was out of her clothes in a flash and shyly walked over towards them with a hand over her pussy and an arm over her considerable boobs. Katherine wasn't sure if she was happy or jealous that of all the women in the high school these were nearly the only other two with bigger boobs than her own, though not by much. Katherine and Heather each stood under individual shower heads where water lightly flowed onto them.

Heather suddenly realized how bizarre Katherine must look to a stranger: completely naked, but with black panties painted on. She couldn't help asking Amy, "Amy, aren't you wondering about Katherine's black panties as well?"

Amy blushed, and acted like she wanted to answer but couldn't.

"That's okay, Amy," Katherine butted in. "Heather is the other person who knows." She turned towards Heather and added, "Heather, I already explained to Amy the other day about the panties. I gave her a very brief explanation about how I forgot them on Friday and you're punishing me for forgetting by making me wear these for a week." She emphasized the words "very brief" in the hope that Heather would get the hint not to say anything more, such as mentioning Kim's role.

Amy smiled, relieved that she wasn't in a bind about keeping that a secret from Heather. "Oh, good," she said.

"Amy already knew?" said Heather, slow on the uptake.

Katherine pressed on. "Yes. Here Amy, why don't you stand here and take a shower while we talk. We were just finishing our own showers." She led Amy to the showerhead next to her own.

Amy grabbed the soap and began to soap up her impressive body. For a moment, both Heather and Katherine just watched Amy showering and admired her remarkable, if slightly heavy, body. Amy might even have given Heather a run for her money in the Homecoming Queen contest if she had the right personality to go along with her calendar girl physique.

But Katherine meanwhile still had no idea how she could explain why a dildo stuck out of Heather's pussy, nor why the two of them had taken so much time away from practice. She wasn't too worried now that the shock of being caught had worn off - it was the clueless and naive Amy after all, so the threshold for believability was pretty low. But she still frantically searched her brain for any ideas to say.

"Amy," Katherine finally began.

"Mmmm-hmm?" cooed Amy as she enjoyed her shower.

"You know how Heather said I had a muscle cramp? Well, she started massaging me between my legs, where my cramp was. And after while, it felt better, but... What was really weird is, all this whitish liquid started pouring out of my vagina. Neither of us could figure that out. So Heather put her hands up in there to see what was happening, and that seemed to just made it happen even more."

"Really?" said a rapt Amy. "I have the same problem too! Remember how you, um, helped me out a few days ago?" Amy referred to the day Katherine and Alan shaved her pussy but tried to be vague since she wasn't sure if that also was a secret with Heather or not.

"Yeah," said Katherine. "I said that it was okay if you touched yourself down there."

Heather looked at Katherine with a very surprised glance and wondered what exactly they referred to. Heather knew that Katherine was one of Amy's "protectors" from sexual mischief, so she found Katherine's new behavior- starting from not wearing panties on Friday up to this- extremely puzzling.

"Exactly!" said Amy, relieved since she wanted to say that, but hadn't since that it was part of the secret, too. "So I began touching myself there, starting that very day. And it seemed like after I did that for a while, a liquid started to come out of me, too! Just like your problem. I was too shy to ask my mom what it was."

"We don't know what it is either," lied Katherine, "but I'm afraid it may be some kind of problem. So anyways... Actually, Amy, why don't you sit down in front of us and show us what you do to make the liquid come out?"

"M'kay!" said a happy and still soap-sudded Amy. She sat down underneath her showerhead and pushed her fingers into her pussy and began to rub. With both arms in her crotch, her boobs pushed out impressively.

Heather greatly desired to reach out and touch them, boobs which were a near mirror image of her own, but she held back very reluctantly and waited for direction from Katherine.

"Anyway," Katherine continued, "so Heather used her fingers on me much like what you're doing right now. And this liquid kept coming out. It would even make me shudder sometimes, and made me feel really good, and hot too."

"Really?" interrupted Amy. "Gosh! That happens to me, too!"

"Yeah. So Heather and I were thinking that it must be something really serious. Heather has been helping me figure it out, in case I'm really sick or something. I get hot like I have fever, so maybe I'm sick."

"Oh no!" cried Amy. "That means I must be sick, too!"

"Maybe," continued Katherine. "But maybe it happens to everyone. We weren't sure. So to test that, I thought we should check with Heather, and see if she also leaks this fluid. So I began rubbing her vagina, too." Katherine wanted to show with a visual example, but Heather's pussy was still occupied with the throbbing, rotating dildo. She appeared somewhat glassy eyed.

"Heather, why don't you show Amy what we mean?"

They all sat now, with the water still falling on them. Heather scooted closer, and opened up Katherine's black pussy lips. She was fascinated by the painted lips and gushy pink interior.

Heather let out a squeal of pleasure as it suddenly occurred to her that they weren't going to get in any trouble at all and that in fact they could keep doing what they'd been doing with Amy a possible extra pleasure.

She adjusted to her new role. "Yes, Amy. Take a look at this. You see this stuff coming out?"

"Yeah?" Amy replied.

"This is the problem. And I'm not even doing anything. Watch what happens when I start doing this." Heather worked her fingers in and out of Katherine's pussy while Amy did the same to herself.

There was a silence for a few moments, except for the sounds of squishy pussy noises. Then Katherine continued, "So anyways, Amy, I did that to Heather for a while, like what she's doing to me now. And lo and behold! She began leaking the liquid too. So Amy, do you know what that means?"

"Wh-what?" Amy had already begun to lose it, due to the ministrations of her fingers. She was very sensitive.

"That means you and I aren't sick! If it happens to all three of us, three randomly-chosen women, that can't just be coincidence. It must happen to everyone."

"Oh... Woooow..." said Amy. Drool rolled down from her mouth, only to get washed away by the shower's water.

"So that's where this big black thing comes in," continued Katherine and pointed to the dildo which was still buried and rotated in Heather's pussy. "We thought, maybe if we can't stop our vaginas from leaking, then maybe we could plug them up with something, and then we could go back out to practice. So we looked all over for something to use as a plug, and couldn't find anything but this thing, which is called a dildo. It's actually made to be a pussy plug. We put it in Heather, and it seems to be working. She still feels really good, but she's not leaking as much, right Heather?"

"Uh? Yeah, right." Right at that moment Heather was distracted by her own orgasms, very turned on between the sight of Amy pleasuring herself and believing the absurd story.

"Oh woooow..." was all Amy could add, as she threw her head back in ecstasy. Soon she and Katherine began their own powerful orgasms. Both of them had their legs spread as wide as they could go, which was very wide for a couple of limber cheerleaders.

Finally, Katherine said, "Amy, would you like to try? Would you like us to stick this big dildo up your pussy and see if it also stops you from leaking?"

"Umm, isn't she a virgin?" Heather asked Katherine quietly.

"No," replied Amy herself. "Jack Johnson raped me last year!" She said this happily like she said most things, as if she described getting an A on a test and not a rape.

The Mr. Excitement dildo popped out. "Here," said Heather to Katherine. Heather was too lost in an erotic fog to do much by this point.

Katherine said to Amy, "Okay, get on all fours and spread your legs real wide again. Then I'll push the dildo in."

Amy immediately did what she was told. Katherine slowly pushed the dildo into Amy's pussy, inch by inch. At least six inches stuck out when it was all the way in.

Both Heather and Katherine were incredibly turned on by Amy's eagerness to assume such an obscene position, without even really knowing why she did it.

"The only problem with this strange dildo thing," added Katherine, "is that it won't keep still! I don't know what it's for, but it keeps shaking all over the place, and turning around. But it appears to be working, do you think?"

"Yes? Oh gosh! Yes!" screamed Amy. "It feels... fantastic!"

Amy writhed around for several minutes. Amy remained in her position of practically doing the splits. She wore a wide, gleeful smile.

Katherine sat behind her and "assisted" the dildo as she ran her hands all around Amy's ass while she pushed the dildo in and out. She "discovered" Amy's clitoris and the wonderful feelings it could cause when tweaked. They all agreed that was another mystery that needed more exploration and understanding.

Heather felt a bit neglected to be without Katherine or Mr. Excitement, but she was nonetheless plenty aroused frigging herself while she watched Amy from behind.

Eventually, Katherine stole a glance at Heather's watch. Then she sternly said, "Heather, look at the time. I really think you should return to the cheerleading practice. I'm surprised Janice didn't send someone else after Amy to see what's keeping her too. Go back there and tell them that I got really sick despite you trying to help, and that Amy helped take me home. We'll finish up here and go home early. Other girls are going to start finishing their sports and coming in here and taking showers soon, so it's really all over anyways."

Heather sighed. She wanted their fun to keep going on and on. She still hadn't been able to play with Amy's ample tits yet. Heather wanted to be in control, but clearly Katherine was much more in the know and thus took charge in this situation. "Okay, I guess," said a reluctant Heather as she got up and began to dry herself off.

Katherine turned to Amy. "Amy, I know it feels good, but you have to finish, too. When it comes to most things with pussies, um, I mean vaginas, it's good to keep them completely secret. You don't want anyone to see you doing this, ever. This is another super-secret, okay? You won't talk to anyone about this except Heather and me, when we're in private. Together, the three of us will solve this leaking problem. Okay?"

"M'kay!" said Amy happily. Then she frowned and looked over at Heather putting on her clothes. When she pulled the dildo from her nether regions, she held it up as it dripped pussy juice everywhere and asked, "But do you guys mind if I borrow this for a little while? It's really neat!"

Katherine realized with great relish that her time to be fucked by Alan would come very soon. But there was one problem: she wanted her first fuck with her brother to be perfect, and not marred by her funny, painted black butt. So she grabbed a rough brush she had brought along for the occasion and rubbed all of the paint off of her. She also had Amy help out.

Thanks to the right implements, Amy's help, and the desire to get the job done as fast as possible instead of playing around, the paint came off in ten minutes instead of the hour it took Alan. Other girls began to come into the locker room right as they finished up.

CHAPTER 5

Meanwhile, back on their quiet suburban street, Susan was lost in her erotic thoughts. She could hardly wait until her husband left for work and her children left for school so she could get naked. And get naked she did.

Oh, dear Lord, I'm so depraved, she thought to herself as she took off her clothes, even as she looked out the front window and saw her husband drive away towards work. I'm growing worse every day! Please, please, I beg of you, Lord, please give me the strength to resist temptation! You know what I speak of. My son. My dreamboat, handsome son. So kind. So innocent. So... Arrgh! I'm getting carried away here. My point is, Lord, I have to resist, don't I? Please! Answer my prayers. Give me a sign, some kind of sign. Tell me what I should do!

By the time Susan had all her clothes off. She moved away from the front window for fear that someone might see. As she walked towards the kitchen with her clothes in her hands, she thought, There's nothing wrong with just being naked. It's not like I'm doing anything immoral. We're all naked before the Lord anyways, right? I just need to release my urges in a private, harmless way. I don't know why, but taking off my clothes makes me feel sooo good. I really don't know why. Maybe it's because I imagine Alan looking at me. What if he could see me right now, what would he do? Would he want to do nasty things to me? Like, would he want to take his magnificent, hard... No. Don't think those thoughts Susan. Just let your mind go blank. ... I think I'll just clean up the kitchen a bit dressed like this.

Susan raised her arms above her head and stretched. Aaaaahhhh.... This feels great. I have nothing to be ashamed about with my body. As a matter of fact, I'm pretty damn good-looking. That's what people say, at least. And the way that my Tiger looks at me sometimes shows that... No. I can't think like that. God, give me strength! Please, Lord, please!

She put her clothes on the kitchen counter and picked up a sponge. Then she paused. Ahhh, shit. Who am I kidding? This nakedness isn't enough. I've gotta go masturbate, like, NOW, just like I did yesterday at this time, and the day before that. I'm doing it too much! Too many times a day. It's like I've become addicted.

But just then she heard the front door open. Oh holy mother of God! Suzanne! Shit! Susan dropped the sponge and ran frantically down a hall way and into the lower bathroom before Suzanne could see her in her complete nakedness.

How stupid of me, she thought bitterly. Suzanne is coming over sooner and sooner these days. She's not even giving me time for a quick masturbation after the kids leave. Damn! And worse, what am I going to wear now?

She looked around the bathroom. To her great relief, she realized a hamper for dirty clothes was in it. She fished around and found a top and skirt of hers that weren't noticeably dirty. She put them on. Then she flushed the toilet, to help explain her absence to Suzanne.

Elsewhere in the house, Suzanne walked around to look for her best friend. When she reached the kitchen she saw the pile of clothes still on the kitchen counter. Hmm. This is odd, to say the least. Susan is normally so neat. I wonder if this was what she wore earlier. I'll have to ask Alan or Katherine later on what their mother had on at breakfast. Hmm.

Susan came out of the bathroom and entered the kitchen. "Hey, friend," she said to Suzanne as she smiled and waved, and Suzanne replied in kind as she sat down at the counter. But Susan had a guilty look on her face - she was a horrible actress and a bad liar. Then, when Suzanne saw her pile of clothes on the counter, her guilty smile turned to open-mouthed horror.

Susan lamely tried to cover for their presence. "Oh, what a mess. Here, let me put these away." She took the clothes and went to put them in the same hamper where she came from.

As Suzanne was left alone, she thought to herself, She's acting guilty as hell about those clothes. What's going on here? Think, Suzanne, think. ... Wait, I get it! She must have been naked in the kitchen when I came in. I thought I heard some running around. I must have interrupted ... what? Why was she naked in the kitchen, all alone? Doing the dishes naked, maybe? There's a sponge on the floor here. Wait a minute. I know what this means. She's so fucking horny all the time now that she's naked or masturbating, or both, every chance she gets! Why, Ron only left a couple of minutes ago. I saw the car drive away.

She's tearing off her clothes just as soon as she can get the chance! That gets ME so hot! Fuck! To think she was so frigid all these years; now she's like a nymphomaniac. And it's my scheme pushing her to Alan that's doing it. This is so great. If she has any bisexual tendencies at all, my bigger scheme to bed the whole Plummer family is really going to come true! No shit! Damn!

Suzanne was lost in a reverie. She had the most blissful and joyous expression on her face, as if she'd just won the lottery. A quizzical "Suzanne?" from Susan snapped her out of it.

Now it was Suzanne's turn to look guilty. But Suzanne was a much better actress. She covered up her true feelings within seconds. "Sorry, drifted off there for a second. I guess I'm still waking up. Still dreaming."

"I know the feeling," Susan said perhaps a bit too truthfully. "Must have been a good dream."

"It's a great one, Susan. My favorite fantasy."

"Oh, sounds fun. What is it?" Susan asked happily. Her earlier guilt and nervousness were gone.

"I can't tell you just yet. Maybe someday. What's your favorite fantasy?"

Susan's guilt flooded back. She stammered, "I, uh, uh, I, I can't tell either." She turned away and blushed.

How cute, Suzanne thought. Talk about being able to read someone like a book. As if we don't both know exactly who she's thinking about in her fantasy. But I just love Susan for her cute and innocent ways like this. What an angel. To think this shy and proper woman was just standing in this same room a couple of minutes ago, completely starkers. It beggars the imagination. ... I must be getting in her way though. I'll bet she'd love nothing better than to fuck herself into unconsciousness, right now, thinking about her hunky son. She must be hoping that I'll leave. This is all getting me so hot, I'd better go do myself back at my place. Good thing no one else is home.

"You know, Susan, I just thought of something. I'd love to sit and chat like this all day, but it occurred to me I actually have an important errand to run. For once in my life."

Susan laughed, but it was still nervous laughter.

"I'd better get going. Let's hang out later. I'll be back in say, two hours?"

"Perfect!" said Susan. That'll give me plenty of time to rub myself. I'm still so worked up!

After a few more pleasantries, Suzanne went back to her house next door. Just as Susan had done with her husband, she watched Suzanne go and waited until the coast was clear. Then she shucked her clothes off. She ran upstairs and hopped in bed. Despite her eagerness to be naked, she still could only masturbate in two places: under the covers of her bed, or in the shower.

Once she returned to her own house, Suzanne took the other alternative: the shower. For security's sake, she didn't dare walk around naked or frig herself just anywhere, in case her son or husband happened to come home for some bizarre reason.

At first she frigged herself wildly in the shower until she came with a feverish intensity. Then, exhausted, she got out, soaking wet, and sat down in the bathroom to rest. She started to think some more, and slowly grew aroused again.

As she ran her hands slowly over her legs, she thought, Boy, that Susan is really something. My seemingly decades-long quest to get her to become more cultured - go to plays, the opera, listen to classical music, appreciate fine wine - it hasn't been terribly successful. But then I try to get her to go after her own son, and she's become a hopeless case in a matter of weeks! This is so much more fun than my culture lessons.

But this path is also full of danger. Not Ron or my husband - who cares about them? The problem is, Susan and Alan might get so into each other that they'll completely forget about me. After all, they have that whole taboo / forbidden fruit appeal thing going on, not to mention such a long and close loving relationship. And I always thought I could out-sexy any woman, but Susan is easily at least my match with her body. I just have three things in my favor, over her. One: a readiness to go farther with him, and faster. With any luck, I can be his first fuck. Two: a more devious and scheming mind, and greater awareness. Three: much greater sexual experience. That's key. That'll be my main weapon to win both of them. I'm sure I can lick and suck and kiss and fuck way better than Susan. And Katherine too, for that matter.

Mmm. Katherine. Now there's another sexy Plummer to ponder. Suzanne's hands had wandered over her wet skin, but now they started to converge on her ready and leaking pussy. What I wouldn't give to get my hands in her sweet hole, instead of my own! I wonder how things are faring between her and my Sweetie. Mmm. Imagine those two going at it together. There's a sexy thought. Very sexy...

Suzanne lost her train of thought for a couple of minutes as she fantasized being a fly on the wall while Susan's two children fucked each other. But after she climaxed, she returned to her strategic thinking. Those two are going to fuck, for sure. But Katherine's like Susan: way too chaste and prudish. Since I haven't been wearing Katherine down as much as Susan, it'll take longer for the daughter's restraints to give way.

Suzanne was dead wrong on that last surmise, because she didn't realize that Katherine had a long-standing secret lust for her brother. Not only that, but she didn't do enough snooping about Katherine's behavior. She thought a little about the need for more snooping. I wish I was closer to Katherine so I could really know what she's thinking. It would be great if we were close the way Susan and I are, and shared all our secrets. I should find out soon how things stand between those kids. I know things are starting to develop, but just how far have they gone already?

Given Alan and Katherine's goody-goody reputations, and Alan's lack of aggressiveness, Suzanne would never have guessed in a million years that the two teenagers had plans to fuck each other that very afternoon. But if she would have known, she wouldn't have been too terribly upset. It fit in with her overall plan to break down all the sexual barriers.

CHAPTER 6

Later in the day and back at school, Amy and Katherine waited for school to end. They found a place to hide from the other cheerleaders, since Amy was supposed to have taken Katherine home already. They hid for about ten minutes after class, until school had mostly cleared out. In the meantime, they talked. Katherine wouldn't let Amy borrow the Mr. Excitement dildo, but told Amy that she had another one at home, and Amy could come by some time and use that one.

Amy was also very sad that neither Katherine nor Alan shaved her pussy more often. After all, they told her that it needed to be shaved frequently, especially in the first week. Katherine promised that both she and Alan would be happy to shave Amy's pussy very frequently that weekend, if the opportunity presented itself. Amy was exceptionally happy to hear that.

But Katherine was pissed at having to sit and wait for the school to clear out with Amy. Alan is expecting me! We finally get to fuck, but here I have to wait? Arrgh! When she finally deemed enough time had passed, she raced home on her bike as fast as she could and left Amy on her bike far behind.

Alan nervously waited for his sister at home when she arrived about 10 minutes later than expected. The two of them had already paved the way for their upcoming fuck session, and even future ones, the night before. They told Susan that a new club had formed, called the S Club, or Service Club. They said it was a club devoted to doing good deeds in the community, kind of like the Key Club, another club already popular at the school. There actually were clubs called the S Club which did just that, which was how Alan got the idea, but there was no established chapter in their high school yet so it made a great cover story.

The two further explained that tomorrow was the first meeting, and since the club had just started out, they would meet every Monday and Thursday. The membership was very small, because meetings were being held off-campus. Therefore, they needed to borrow the car. That was a necessary lie, because Kim's house was quite a distance away.

So Susan was delighted and readily agreed to loan the car any time they needed it for S Club. She encouraged them to join more such clubs, especially since it would look good on the college applications, which were coming up soon. Susan even offered to drive them there, but Alan said that would make them look uncool to the other club members, who all had their own cars. (Surprisingly for such a rich family Alan didn't yet have his own car, but his father's car was essentially his since Ron was never around.)

Alan and Katherine managed to fuck each other with their mother's full approval, in a certain sense. The ever-resourceful Alan had managed to procure a box of condoms as well. Kim also phoned them and gave the all-clear sign, so everything was ready.

Alan drove. As they got in the car, Alan said, "Sis, you scared the shit out of me. I thought for sure you chickened out. Those last minutes before you showed up I was practically having a panic attack."

"Are you kidding, Big Tasty Brother? I wouldn't miss this for the world! You're going to make me a woman!" They both settled in their car seats in the driveway, and Katherine leaned over to kiss Alan on the mouth.

He let the kiss linger, but when it was done he looked around frantically and said, "You're trying to kill me, you know that? We're still in our own frigging driveway! Mom could see! Just wait a few minutes, please!" He started the car.

"Sorry, Bro. Or should I say, Big Hard Sister-fucking Brother."

"Hey wait a sec." He put his head down on the steering wheel and inwardly groaned. "Sis, when you say things like that I feel so torn. Is what we're thinking of doing here really right? Is it, is it wrong? Even if you say no, isn't it going to end badly? Don't you feel a bad end?"

She held his head in her hands and turned it to look at her. "Listen to me, Alan. This isn't wrong. I love you. You love me. Forget about the mores of the town. I don't care what they think or even know what the law is on this. This feels right. You know it, and I know it. We love each other and always have, and this isn't going to end badly because we still will always be in love, no matter what happens. And Mom will love us even if we rob a bank. So let's just forget everything and have fun. I know I'm going to have a hell of a good time, and love every single, unforgettable second."

That made him smile. He kissed her deeply, though quickly. He was glad that he had, for he tasted a pleasing hint of mint on her lips and could smell the musky aroma of her skin. "I don't doubt you will. And you're probably right about everything. It just feels so momentous. It takes my breath away. But I'm so excited too. I'm so trembly. Let's get going before I die of anticipation." He turned the car engine on.

"Tell me about it!" she enthused. "I just get so uncontrollably excited thinking about the fact that we're going to be making love in mere minutes! I'm so turned on! Not only that, but the most interesting thing happened to me at school today."

"Tell me about it," Alan said as he drove the car out into the street. He thought whatever she would have to say could take his mind off of his lingering doubts.

While he drove the car down the road, Katherine talked dirty and told him the hot and sexy story of what had happened to Heather, Amy, and herself during cheerleader practice. Since Susan might see them leave or return, they had to wear relatively normal clothing. Alan wore a T-shirt and long pants, and Katherine wore short shorts and a tube top that had a slit down the front and exposed all of her cleavage.

As they sped through traffic, Alan could look over and see Katherine's magnificent boobs jiggle and shake. He blessed the car's bad shock absorbers. He admitted that her boobs weren't nearly as big as the almost unnaturally sized tits of his mother or Suzanne, but they would still be the subject of masturbatory fantasies for just about any guy at school.

He thought, Between Amy and Sis, I've got the inside track on at least half of the most jaw-droppingly beautiful and big-breasted girls in the school. And then there are certain other women at home. Definitely a one in a million or even billion situation. Wow.

But right now he could think of little else but Katherine. Within a few blocks of leaving the house, she sat down in the space in front of the passenger's seat so Alan could better see the show she put on. She grasped at her breasts and pulled down her short shorts past her knees so she could frig herself. Alan was freaked out that she now wore nothing but a tube top, but as she was crouched down, no one could really see what she did or what she didn't wear.

As she continued to tell her arousing story, she reached over and placed her hands on the bulge in Alan's pants. She began to massage it through the clothing.

Alan prayed that they would get to Kim's house soon, before he had an accident. Between her story and her hands, his doubts completely disappeared from his mind. Lust took over.

She stopped telling her story and said to Alan, "You really need to get new pants, because this one has a defective zipper. Look - it's unzipping all by itself!" She pulled his zipper down as she said this.

Alan placed his hand over the hole in his pants she just opened to prevent her from going any further. "Sis, you can't! I'm driving, for fuck's sake. How would you like to get us killed right before our big moment?"

She was unfazed, and giggled, "Hey, don't blame me - it's the zipper." Alan had to keep at least one hand on the wheel, so with more hands she managed to get his hand out of the way and pull his penis out of his pants.

"No, Katherine, no!" he cried in a very agitated state. "Please! I beg you!" They stopped at a stop light, and he pulled at the hair on his head with both hands in frustration and sexual arousal. "We're gonna die. I know it. Die." He said this dramatically and fatalistically. The car started moving again, and as though to drive the point home, he nearly struck a mailbox on the side of the road and missed it, he was sure, by mere inches.

"See?!?" he griped. When the car came to a rest at another stop light he stared at her wide-eyed with fear even as she steadied herself from the slight jolt. Luckily no police cars were around to see the near-accident. Alan was worried the police would think he was driving drunk.

"Chill already," Katherine chided him. "Okay, fine. If you're such a bad driver, your loss. I suppose this wouldn't be the best time to die. I won't give you a blowjob after all, and I'll take it easy until we come to stops at the traffic lights. Like this one."

She frantically jacked him off until the light changed and then just kept the penis throbbing in her hands as he drove on while she waited for the next light. She resumed her story, but Alan was too focused on her hands and trying to prevent an accident to pay attention to her words anymore. Still, her ministrations on his penis didn't really stop, they just slowed down, and it drove him out of his mind with desire. He passed a few hotels on the way to Kim's house and seriously thought about stopping and running into one of them with her, unable to hold out even another five minutes.

CHAPTER 7

After a fifteen-minute drive, they finally reached Kim's house. They were both so worked up that neither of them had the slightest reluctance to fuck each other anymore. Alan pulled the car into Kim's driveway and they ran into Kim's house as fast as their feet could carry them. Alan sported such a massive wet spot around his groin area that it looked almost as though he'd pissed on himself. But he didn't care how funny he looked - he just wanted to get to a bed.

Katherine practically ran over Kim, who stood in the front doorway to open the door. Kim was still dressed in her cheerleader uniform, which showed off her trim and petite figure nicely. Katherine briefly French kissed and groped her then frantically asked, "Where's the bedroom?" It was clear that she did not want to waste another moment. If her voice wasn't a clear enough indicator, then her nipples certainly were; they were so erect that even her areolae looked puffier than usual.

Kim just smiled and pointed upstairs, and brother and sister ran upstairs in a flash.

They sat on the bed, as Katherine urged, "Quick, Alan, get the condoms!" They'd had plenty of foreplay in the car, and were ready to dive right in.

Clothes flew into the air, and Alan fumbled around with the condoms. Katherine impulsively reached out for Alan's hand. She suddenly appeared calm as she said, "Brother, thank you. I know that this is going to be the greatest, most exciting day of my life. And the best part has just started! In a minute, neither of us are going to be virgins anymore."

The two held hands for a brief pause. He looked in his sister's brown eyes, saw the passion and excitement there, and said, "I love you, Little Sister!"

She looked back with a high, rosy color in her cheeks, and said, "I love you, too, Big Brother! And I'm so glad we've found a new way of loving each other." They kissed with passionate intensity. Katherine's heaving breasts brushed against Alan's chest; her nipples were hardened rocks which poked into him like hot coals.

Katherine finally pulled him away. "That's great, but let's not wait another second!" She lay down on Kim's bed, face up, and said, "I'm waiting for your big cock!" To further illustrate her words, she opened her thighs wide and ran an index finger over rigid clit, which was engorged and stood out from its hood proudly.

Alan sat up on the bed, straddled her, and positioned his penis above her fuck hole. Drops of pre-cum fell onto her shaven mound. He looked at her and she wordlessly gave approval for him to go on as she hooked her heels around his waist. He took a big breath and tried to clear his mind. His whole world, now, was his sexy, lust-filled sister.

His smaller sister practically writhed beneath his body in anticipation, hot and willing to accept him into her body fully and completely. She breathed up at him quickly. She thought, I feel like I've just run a marathon, and we haven't even started to fuck yet!

He pushed the penis down into her. It slid down ever-so-slowly into her very tight pussy. Every sensation in his body seemed to disappear for a moment, except for a spine-tingling focus on every nerve-ending on his dick. Warmth, wetness, tightness and softness - those were the sensations which filled his mind. And, as wonderful as it felt to slowly, achingly slide his insistent penis into his sister's depths, even more wonderful was the sense of oneness and love he felt radiating between himself and his sister like an invisible field of energy.

There were a million things he could say, but all he could manage was a guttural "Ugggh!"

"Oh, yeeeeesssss!" she yelled in return, a cry of release and pleasure. Although she'd never had a penis inside herself before, from the very first instant it was in her, it felt fantastic. She felt the fullness, heat and rigidity of her brother's penis as it moved and throbbed deep within her. His whole body covered her and enveloped her. They fiercely clutched their hands together.

Already she began to feel the onset of mini-climaxes, even though Alan had not yet begun to move inside her body. She was very glad that her hymen had been broken in an accident five or so years ago, so there was no pain or blood. She could feel her brother's hot breath beat down on her neck.

Alan slowly pushed his penis in until he felt it could go no further, sure that he'd hit the impassable entrance to his breathless sister's cervix. He stayed there for just a moment, to enjoy the feeling of being so deep within her, until she subtly wiggled her hips beneath him. She was eager for more.

So he slowly began to pull it back out. The coolness of the air around the shaft of his penis as it emerged was an extreme contrast to the heated depths he'd enjoyed just a second before. Then he pushed in again slowly, as though driven by a deep, primal urge. Then out. In and out.

He built up a rhythm and reveled in the fact that his sister, too, had begun to move in sync with his gentle thrusts. His sister, cheerleader or not, had always seemed so soft and fragile to his protective, brotherly mind that he didn't want to hurt her. When her upward thrusts became more powerful, such fears were quickly put to rest and he began to push his thick meat into her body all the way up to the hilt. She wrapped her arms around the back of his, holding on to him as if she were on a wild roller coaster ride.

"Yeeeeeessss! My brother is fucking me!" Katherine screamed at the top of her lungs as her plentiful breasts moved madly with the motion of Alan's thrusts. The sound carried into every room of Kim's house, but Kim had assured them earlier that they could yell to their heart's content and the neighbors would never hear, provided they kept the windows closed.

Kim meanwhile sat in the room next door and fucked her own pussy with a dildo as she got off on their sounds and screams. Even from a room away, she could already start to smell the pungent odor of their sex. It drove her wild with envy and passion. She shoved the dildo as deep inside her as it could go as she imagined what it would feel like to be in Katherine's position just one room away.

"We're fucking! We're fucking!" screamed Alan joyously. He, too, reveled in the freedom to yell to his heart's content, after weeks of furtively and quietly sneaking around in his secret sexual life. He yelled as loud as he could, "I'm fucking my own sister, and I don't care! Wooo yeah!!!"

Their thrusts were no longer anything like the soft shoves from a moment before - they were steaming along in an insistent and solid rhythm. Alan pistoned his penis into her as deep as it would go and marveled at the hot-cold-hot-cold sensation of each insertion and extraction of his penis as it pounded into her, seemingly on its own volition.

"Fuck me! Fuck me! Fuck me!" she yelled in time to his thrusts as her large bosoms slapped against his body. "More! More!"

There was no pretense at drawing anything out. They just wanted to cum as fast as humanly possible. Arms and legs became a blur of activity as they threw their bodies into one another and the powerful scent of sex literally poured out into the room from where they were joined in incestuous abandon. Things moved at a feverish pitch until neither brother nor sister could hold back any longer. Both teenagers stiffened as their bodies cried out for release. They reached climax together while yelling a seemingly endless stream of incoherent screams.

Alan felt his jism course through his prick, like a fire hose suddenly filling up with water. Then his semen exploded out of his penis and filled the depths of his sister's vagina. Alan thought, I'm doing it! I'm doing it! It's happening! He continued to push his penis deep inside her and, almost instinctually, stopped on the downstroke so that he could completely fill her up with his seed.

Katherine could feel the coursing and throbbing of his penis, timed to the beat of his heart, and then the splash of his seed filled her pussy, flooding her with a tremendous warmth. All of a sudden it occurred to her that she shouldn't be feeling such sensations. The condom! Where's the condom? Too busy kissing - we forgot! Ah, hell. Just sit back and enjoy it. Oh fuck! God! So good! Screw it! Screw ME!

She calmed down enough to begin making sense with her screaming, and shrieked, "Screw me! Screw me! Screw me!" over and over.

Alan collapsed onto Katherine. The two just lay quietly for a minute, as they recuperated and breathed heavily from their exertion. Both of them could feel Alan's semen as it slowly bubbled out of Katherine's cum-filled pussy and around her brother's semi-erect penis. He rose just slightly enough off her body so that he could look into her eyes. All he saw there, as she looked back up at him, was love, tenderness and deep appreciation.

Alan asked, "Did that hurt at all?"

"Not in the slightest," she replied. "It felt like your cock was born to be inside of me. A finger or dildo just doesn't compare with the real thing! Now that I know how good it feels, I want your cock inside of me every minute. Every minute of the day. Tiger," - she strangely used their mother's term of endearment for him for the first time - "do you promise to fuck me every minute of the day, for the rest of our lives? Will you make me your complete fuck tool?"

"I'll try my best," he answered, and laughed gaily. Yes! Yes! a joyous voice inside his head continually shouted while she happily squirmed in joy beneath him. He was on the highest of highs.

He thought out loud, "You know, it's really amazing to finally fuck a woman. But for that woman to be you, my sister, it's just out of control. I can't believe it."

Katherine hugged him firmly, and said, "I know. It's my first time too. We're on the same wavelength. But let's do it again, already!"

"Okay! I should have no problem getting ready to go with you to arouse me. But you know, it's funny, I'm really thirsty all of the sudden."

"I'll get you some water!" they heard Kim yell at them. They hadn't closed their door and she could hear even their whispers.

A minute later she walked in with a glass of water in her hand. She was buck naked now like them, and pussy juice visibly dripped down her legs. "Don't mind me," she said. "I'll leave you two alone for your special time together, but I just had to say you two are fantastic."

She handed the water to Alan. "I'm shaking like an earthquake in the next room, just from hearing the sounds of you two. I can't wait to watch, or even get that big thing stuffed inside of me. I wish I had a brother to fuck too, but I'm an only child. Now drink up, big boy, and give us round two."

They all smiled at each other. "Alan, your fuck toy is waiting for you," Kim added in a husky voice, with a strong emphasis on "fuck toy." She walked back out of the room.

CHAPTER 8

Alan said to Katherine, "I like the sound of that, what Kim just said: fuck toy. Are you my fuck toy?"

"You know it!" she replied enthusiastically. "I live just to be fucked by you! Now I can tell you something. I've wanted your thing deep inside me even before you started your medical treatment. I've secretly wanted it for years, ever since I saw you naked and aroused in the shower one day. That's why I never went all the way with any guy, and was so prudish. Well, that, and trying to be like Mom.

She continued, "But I don't think I ever would have acted on it if it weren't for what happened these past few weeks. I figured you were - and still are - such a goodhearted, morally upstanding guy that you'd hate me if I expressed any sexual feelings towards you. And I was chicken. God, I was unhappy sexually and didn't really understand why. I could barely even admit my feelings to myself. But now that's all over, thank God, 'cos I have you."

Alan was very surprised by all that. He was fairly amazed she would eagerly call herself a fuck toy and the rest was even more amazing. He never had the slightest clue she felt this way. He decided he'd mentally absorb all this information later and just get back to fucking.

He made to slip his penis in her again as she sat on top of him, but she stopped him. "Wait a sec, Big Pussy-stuffing Brother. This time, let's use a condom." Even as she said this, a few drops of the cum Alan had already spent inside her pussy dribbled out onto his now-erect penis.

"Oh fuck! Oh my God! I'm so sorry! I totally forgot!"

"Don't worry. I know someone in school who has some of those day-after pills. I'll take one just to be on the safe side. Actually, I'm really glad you forgot. It's sooooo good to feel your naked flesh in there and not the latex of a condom. But we should start getting in the condom habit. Next time. For now, what's done is done, so fill me up. Let's not leave the little spermies in there all lonely. Give them some new friends!"

She'd sat with his penis poised at her pussy lips and lowered herself down onto it, driving it all the way in her. Alan commented, "Man, you are one sexy woman. Dangerously horny, too."

"Mmm. Big Sexy Sweaty Brother, this time let's take our time." She clenched her pussy muscles tightly and wiggled her bottom. The feeling of fullness while she sat on top of her brother with his penis buried so far up inside of her nearly overwhelmed her, it felt so great.

Alan was happy with that idea. They proceeded much more slowly, like they fucked in slow motion. He gradually pushed his penis deeper and deeper, up to the very hilt, and then pulled back just as slowly until all but the tip of his penis was out of her pussy. Then he did it again. And again. He watched with awe as his sister's tits began to bounce slowly with each upward thrust of his penis.

"God, I can hardly wait until you cum inside me again!" she sighed with a shudder.

"I would say what you just said really turned me on," he responded, "But there's no way I can be any more turned on than I am already. ... It's funny, 'cos I never really thought about you in that way. You know, before this all started. Boy was I wrong! Jesus. Just think about all the wasted nights with our bedrooms across the hall from each other, and no fucking going on. What a tragic waste! Now, help me make up for lost time."

She sighed sadly. "Don't remind me! I feel the exact same thing. It's like a physical pain to think about all the opportunities we missed. You're just gonna have to fuck me that much more to make it up to me."

Katherine rose up just the tiniest bit to give him more room to thrust up into her tight, cum-drenched pussy. He pounded her relentlessly and ever so slowly increased his pace. Then they rolled back over so that he lay on top of her and they kissed and ran their hands everywhere. There wasn't as much screaming now since they were too busy kissing. The two siblings basked in the warmth and glow of their love-making.

Just as the pace reached a frenzied climax, he pulled out altogether. She suddenly felt empty inside, like someone had taken a part of her body away from her, and hated the feeling. "What are you doing?!?!" she yelled incredulously. "Why did you stop? Fuck me more! Harder! Fuck me now!"

From the next room they heard Kim yell, "Yeah, what's the big deal? Give her what I need! I mean, what she needs!"

"Slow down, you two," Alan said, as he tapped the head of his penis on his sister's red and swollen clit. That made Katherine arch her back in response, hopeful that she could impale herself on his fuck stick. "In these few weeks of my limited sexual experience, I learned that delayed gratification is twice as sweet. Let's hold off as long as we can and take our time. Not only that, but I DO have some condoms in a pocket somewhere around here, so I might as well use one before I cum again."

They caressed and kissed until Alan's penis was ready with a second wind. He put a condom on, then started again slowly and caressed her gently as he slowly pumped his hips.

There was a very obvious difference with the condom on. While Alan's penis still felt very warm inside Katherine's hot, tight pussy, there was no sense of wetness and the skin-to-skin contact had completely disappeared. It was still pleasurable to fuck his sister, even with the condom on, but if he had to choose, he far preferred going bareback. Still, though, he figured that he would have to get used to the feeling of a condom, at least until the birth control pills from nurse Akami would begin to have their effect on Katherine.

He began to pound his sister with renewed vigor. In a sense, the desensitization of the condom actually helped to prolong his stamina, which was undoubtedly a good thing for her.

"Last time was good," said Katherine, "but give me all you've got this time!"

"Hey, I gave you all I had last time," he chuckled.

"Give me more! Even more! Fuck me! Go deep! Break me in two! Fuuuuccckkkk meeeeeeee!"

Alan gladly obeyed her. He literally bounced his hips up and down on her body, making his shaft slide thoroughly in and out of her. He would rise up and his penis would be completely exposed to the air and then he would pile-drive the pole right back into her upturned pussy as far as he could go. They screamed and squirmed and climaxed. Sweat flew everywhere and Alan's cum squished out of the condom as it filled to overflowing all over the outer lips of Katherine's well-used vagina.

As they lay back and rested again, Kim poked her head into the room. "Thumbs up on round two, y'all," she said as she flashed them the thumbs-up sign. They all laughed, and then Kim said, "That gives me an idea," and stuck her thumb up her pussy. Everyone laughed again.

Katherine said, "Good idea," and stuck Alan's thumb up hers.

As Kim walked out of the room, she said, "Do either of you want anything this time?"

Katherine yelled back, "I'll take my brother's wide, thick, meaty cock deep in my pussy, please! And I'm thirsty, too. But don't get me a drink - I know just where to get all the tangy sweet cum I could ever need! At least until they put it on the cafeteria menu." She switched positions and began to suck his penis.

"Hey," said Alan. "You can do that anytime. Let's fuck some more, and when I'm ready to shoot, you can suck me off."

"That's a hard sell, mister," giggled Katherine. He sat back, and she sat up on all fours, and poked her ass towards his face. "This time, let's try doggy-style! So many things I've been reading about that I can finally try out for real."

Alan thrust his hips forwards at the same time Katherine thrust her ass backwards. Alan was amazed at the difference between this and fucking a motionless body. They worked in perfect rhythm. Not only did her pussy muscles clench each time she thrust back at him, but his own posture made it possible to thrust with less exertion, which meant that he would last even longer.

Both Katherine and Alan laughed a bit nervously, because neither had yet told Kim of Alan's medical diagnosis of needing to orgasm six times a day. Apparently Kim had picked the number out at random.

Katherine turned towards Alan lying beside her and said, "Wouldn't it be delicious if Kim really was our mother instead, standing there like that?" They both grinned widely.

Katherine reached behind herself and found his penis. "What do you think Mom would think about this?" she said as she guided it into her pussy, even while Kim watched her do this with intense interest and longing.

Katherine then said to Kim as a way of explanation, "We haven't really talked about it, but I think it's safe to say that both Alan and I have fantasies about fucking our very fuckable mother, Susan."

That statement came as quite a surprise to Alan - he had no idea Katherine felt that way towards Susan. But now that he thought about it he realized he shouldn't have been too surprised. He didn't let the surprise distract him for too long, however, and continued to slowly push his meat into her from behind.

"Now there's a fantasy I can get into," said Kim as she absent-mindedly grabbed one of her nipples and gently twisted it. "I've seen her at some school functions. I don't think anyone failed to notice her. That woman is so stacked! With the way she looks, it seems bizarre that she's just a housewife. I'm surprised she hasn't been kidnapped by a rich Arab sheik or something, to add to his collection."

Alan naughtily suggested as he ran a hand over his sister's left breast, "Well, if the Arab sheik isn't going to do it, maybe we should kidnap her, and make her OUR sex slave." Thinking about his mother made him think about tits, so he played with Katherine's.

Katherine added with a devilish smile, "Imagine her all tied up and yelling, 'Help me! Help me get fucked by your big cock, Son!'" She bucked up against his thrusting hips and added, "Just like you're doing to me now, Big ICBM Brother."

"ICBM?"

"Intercontinental Ballistic Missile." She giggled, as she said, "Or maybe Inter-cunt-inental Ball-slapping Muff-stuffer. I'm not sure."

Alan laughed. "But you know, about Mom, it's like you read my mind." He thrust himself into his sister's pussy forcefully some more. "How did you know I've been having fantasies about her lately?"

"Bro, sometimes you're so thick. If you weren't having fantasies about her until recently, then that made you the only one in town. It's like we've got Jayne Mansfield for our mom."

"I guess I am a bit slow at times, Sis," he huffed and puffed. "Hey, why'd you pick Jayne Mansfield of all people?"

"I was trying to think of a famous actress with really, really big tits." She reached her hand up to her own tits. Diving between Alan's mauling hands, she tweaked her own nipples. A shiver went down her spine, which caused her body to shudder some and made her pussy throb even as Alan continued to plow her slowly and deeply.

"Oh. Good point. Anyways, of course I'd never do anything with her, since she's too nice, but imagine her coming to pick us up one day, and finding the three of us in a three-way. And then instead of getting mad, she rips off her clothes and joins in! I could imagine that actually happening!" He felt obliged to belatedly add, "Of course these are just fantasies - I would never really think these thoughts of actually doing anything..."

Kim interrupted, "You two are getting me so hot again! How about we trade moms? Mine's a dear, but she's really let her body go to pot. Anyways, do you mind if I watch this time? I mean, since I kinda of am already."

"Sweet Little Sis, you mind?" said Alan, "It's fine with me."

"No prob, Big Hunky Brother. Pull up a chair, Kim, and imagine him pounding into to you on Monday."

Kim smiled broadly. "I think you just might convert me from lesbianism. But then Katherine is bound to convert me back all over again."

All three fucked and fingered for what seemed like an endless amount of time. Alan worked on his fourth ejaculation and it seemed like he could stay hard forever as he lazily fucked his sister on the bed. The powerful scent of sex in the air grew even thicker with each passing moment.

Kim sat in her chair and worked on her own orgasms. Or at least she tried to sit in her chair. Sometimes she would get so excited that she'd stand up and be practically over them next to the bed while she furiously masturbated herself.

Alan was half-convinced that she would end up in bed with them, and didn't exactly mind the prospect, but she restrained herself. She knew that Alan was too nice to turn her away if she wanted to join them, but also that it needed to really be Alan and Katherine's time with each other.

She also grew more vocal as the afternoon went on and acted more and more like the cheerleader she was.

"Come on, Alan! Fuck your sister's pussy!" Kim cried while she frigged herself. "Show her how good you are, what a good brother you are. Slip it in and fuck her hard! Fuck her deep! Take your big bone and ram it into her. Plant your cock in her pussy!"

"That's what I'm doing already!" Alan cried out in amused frustration. He and his sister had moved back into the doggy-style position so that he could hammer into her more aggressively.

"Well keep doing it!" Kim yelled back. "Give her the fucking of her life! Fuck her tight, steamy pussy with your monster boner! Stick that bone! You're her brother - fuck it like you mean it!" Kim liked to point out every few sentences how the two of them were brother and sister, as if they didn't know that fact already. But that encouragement helped keep everyone steamy hot.

At one point, Alan's energy flagged, and he had to take a breather. Kim though, hopped up, ready to help. "Hey, I am a cheerleader after all. I think you two could use some inspiration." She disappeared for a minute and then came back with her pom-poms. Still naked, she started jumping around, shaking the pom-poms. She made up an improvised cheer:

Fuck her hard
Fuck her deep
Make her cum
And make her weep!

Alan and Katherine burst into laughter. Katherine in particular got the "sillies" - she just couldn't stop laughing. Kim's presence was most definitely appreciated.

The whole time Kim had been in the next room, she imagined that it was her instead of Katherine getting fucked. She continued to think along these lines: Katherine is so fucking lucky! Imagine having Alan as a brother! And then Susan as a mother! Fuck! Insane! I never knew I could get off on incest until these two came along. Now I'm soooo jealous. Fuuuuccccck! Oh God! Fuck each other! Ah! Yeah! Fuck me!

Katherine began to have little orgasms until finally it all merged into one massive orgasm for her. Just as she began to wildly buck under Alan, he shot his hot seed deep into her vagina, stopped only by another condom. Kim, too, came with them and staggered back into her chair.

Eventually they all shook out of their reverie. Kim looked around and her eyes fell onto the clock. "It's been more than thirty minutes!" she yelled in sudden agitation. "We're running late. And how am I going to get these sheets cleaned up in time? I wasn't expecting a lake of cum. Shit! I guess I'll have to start the washing machine right now."

"Should we shower together?" Katherine asked her brother in a sexy voice. They dripped with sweat and cum.

He replied, "That would be another amazing first, but I'm tot
