————————————————

All this took place in complete silence, except for Susan's heavy breathing. But the horny mother finally asked, "Well? Any ideas?"

Katherine was increasingly excited by her mother's display and talk as well. She was even more delighted that Alan was playing with her pussy in imitation of what he was seeing their mother doing to herself. She frantically pumped on his dick.

The only problem was that Alan and Katherine had never finished their breakfast, so their oatmeal was getting cold and soggy.

Alan was so aroused yet frustrated by Susan's comments that he said, "Mom, you can't talk like that! Are you trying to get me to fuck you? Because if you are, you're doing a pretty good job. I could almost pound a nail into concrete with my dick, it's so hard! But you're really just teasing me, aren't you? Tormenting me!"

"Sorry, Tiger; sometimes I get a little carried away," Susan said, genuinely apologetic. She straightened up and forced herself to look him in the eye. "Of course we can't really fuck, so I'll tone it down. Teasing is just so much fun for me now that I've discovered how to really do it. Sometimes I forget how frustrated it can make you. Let's not tease or talk about THAT subject; we'll just stick to blowjobs and titfucks and the like." She looked at Katherine's arm jerking up and down, remembering what her daughter was doing. "And handjobs," she added pointedly.

"Yeah, thanks," he said in an exasperated tone. "But you don't have to go so far in getting me aroused. Just knowing you're near usually does it to me. Thank God I'm not a virgin anymore or you would have torn my heart with your teasing. It's pounding now anyways, thanks to your little pussy show. Damn!"

Susan said apologetically, "Oh dear. I don't know what's with me today. How 'bout if I turn around and stop, um... touching myself?" She turned her back to her kids.

Katherine felt irked, especially that Alan had chosen Amy to be his girlfriend rather than her. Even though she loved Amy like a sister and wanted the best for her, and even though she understood the practical reasons for his decision, she'd still had trouble sleeping last night because she was so upset at not being chosen.

She couldn't help also getting greatly aroused at her mother's display, even though she knew that the show wasn't meant for her. The fact that Susan had turned around didn't help much, since she was pretty much just as drop-dead gorgeous from that angle as from any other.

Alan could sense his sister's growing arousal, so he really went to town on her pussy lips and clit. He furtively pumped two fingers deeply in her slit, even working her G-spot.

Katherine bit down on her lip to keep silent as she started to cum right there on her stool. She worried that if she screamed out in ecstasy, Susan would come over and interrupt them in disapproval. After all, they were supposed to be helping Alan, not getting their own jollies.

Despite Susan not being able to see directly what was happening, she could sense Katherine's cumming, since the strangled attempt not to climax loudly was something she'd personally recently experienced quite often. She pretended not to notice. She could have made a big deal out of all the rules violations going on a few feet away from her, but she felt that Katherine deserved some slack since her daughter had good reason to feel that she hadn't been getting enough attention lately, especially after what had happened the night before with Amy.

"Well, let's talk about something else then," Susan said, still panting, still openly playing with herself. "Who are these other girls at school anyway?"

Alan didn't want to say; he prided himself on not kissing and telling. Besides, he was concerned that she might keep prying and eventually figure out that his sister was one of them. So instead he changed the subject. "Hey, Mom. You're driving me crazy. I mean, not only does your ass look friggin' fantastic, but the fact that you're totally playing with yourself, it's just... Jesus! Oh God! The way your bare ass is gyrating around... your long, sleek legs..."

His voice was ragged and his heart was pumping hard because Katherine had only paused for a few moments to recover from her own climax before her hand was back, sliding up and down his boner. He felt like his orgasm was imminent.

Susan chided him, "Son! What have I told you about taking the Lord's name in vain?" But that was just an excuse not to address his point that she was still fingering her pussy. She was so extremely horny that she felt like she couldn't stop, even after it was pointed out explicitly. However, gathering her willpower, she finally managed to stop and turn around. She hoped that the fact she was facing them would force her to keep her hands otherwise occupied.

Katherine responded by quickly taking her own hand off Alan's erection. In the heat of the moment, she couldn't remember what their mother was permitting that day, so she decided to play it safe. However, she soon realized that her mother was too horny to care.

Unfortunately for Katherine, Alan desperately needed a break. So when she brought her hand back to his crotch, he politely yet firmly fended her off.

Hoping to redirect the conversation before her own blatant masturbation again became the subject of discussion, Susan asked her son, "What was that you were saying about the other girls at school?"

He just responded vaguely, "I can't share any names - a gentleman doesn't kiss and tell. But I can say that it's mostly been a couple of the cheerleaders at school." Technically that's correct, he thought. He hoped Susan wouldn't recall at that moment that Katherine was one of just five varsity cheerleaders other than Amy, since he'd made clear the other night that he hadn't fucked Amy yet.

Susan was filled with pride. Oh God! Too hot! I knew it! I just knew it! Cheerleaders! They're the sexiest, most desirable girls in the school! But of course. Tiger will settle for nothing less than the very BEST!

This news was simply too arousing; her resolve not to masturbate in front of her children vanished in that instant. She wantonly ran both hands all over her bare breasts before sending one hand back to fingering her pussy. "That's my son! Nothing but the best and hottest cunts in the school for you. Of COURSE you should fuck the cheerleaders! Big-titted cheerleaders, I hope?"

"Well, of course." That wasn't true, since Kim wasn't very well endowed, at least compared to Susan, but he knew what would make his mother most happy and horny.

"GOOD! As it should be. So hot! I hope you give that bitch Heather a good hard pounding to melt her brains and show her that she belongs beneath you, impaled on your sperm-filled manhood!"

Alan was amused at her enthusiasm, although he tried to act nonchalant. "Actually, I already have." He was only human, and his pride was surging so much that he couldn't help but reveal that tidbit. Besides, he knew Katherine was aware of that already.

Susan was so excited to hear that that she reached across the counter and gave him a big hug. "Oh, Son! That makes me so happy to hear! I have to say I'm impressed. She's definitely Alan-worthy. Spear that blonde bombshell's cunt real good for me, won't you?"

Alan just nodded in reply. He didn't know which was more surprising: his mother's newly dirty mouth, or her genuine pride and enthusiasm in hearing that he had fucked some of the cheerleaders. Like almost everything else, it was all too mind-blowing for him to contemplate in detail, so he just accepted it as part of his new bizarro world.

What he didn't know was that everyone else, even his mother, was having a lot of jealousy issues over the fact that he'd made Amy his official girlfriend. It was one thing to hear about his new conquests; that always excited her because it reaffirmed his studliness in her eyes. But she was particularly worried that he'd spend so much time with Amy that he'd have less time to spend with her. She realized that was selfish, so she consciously tried not to think about Amy, instead just focusing on the image of a naked Heather screaming bloody murder as Alan's thick erection drove deeper and deeper into her (presumably) tight, tiny slit.

Katherine, meanwhile, was still refraining from jacking off Alan, since he had indicated that he still needed his break. Instead she went to the kitchen to get something more to eat. After all, she and Alan were supposed to be eating breakfast.

Susan was disappointed to realize that Alan's dick was no longer being tended to, but she could hardly order her daughter to resume her stroking when their need to eat breakfast took precedence. She walked around the counter to take care of it herself.

But before she could get there, Alan saw her intention and said, "Hey, Mom, thanks, but I'm taking a strategic break right about now, which is why Sis stopped."

"Oh, poo! Those darn strategic breaks. I love 'em and hate 'em at the same time." She walked back to the kitchen. Unintentionally, she let out her frustration by criticizing her daughter's clothes.



She complained as she leaned against the counter right across from where Alan sat. "Angel, I hope you're not planning on wearing that around the house all day."

Katherine was wearing another item that she and Suzanne had bought at the sex store a few days earlier. It was hard to call it a 'dress'; it was really just a few thin straps of cloth. There was one strap around her waist, two shoulder straps about an inch wide that barely covered her nipples, and one in her ass crack that also barely covered her vulva.

Katherine stopped and stared at her mother. "Why not? It's no more revealing than what you've got on, if you think about it. I mean, you couldn't even cover your boobs if you wanted to. There's just no fabric there."

"Yes, Angel, but this is an apron. I have to wear it for cooking," Susan said, having conveniently forgotten that she owned other less blatantly erotic aprons, or that she could wear clothes underneath the apron. She also conveniently ignored the fact that the straps of her apron had slid down to her elbows, causing the rest to slide so far down that it was barely on her at all. She pulled the apron back into place and then complained, "But your outfit - it just seems so absurd."

"But Mom, last night you said we could wear just as much or as little as we wanted, any time we wanted."





Susan sighed. "Sometimes I say things in the heat of the moment that I may not agree with later. Today is different. Besides, I don't really have any say in the matter. If I don't wear something super sexy, Tiger will just force me to change my clothes, or wear no clothes at all! It's so unfair!" But the mere thought of being "forced" to do naughty things by her son got her motor running again, causing her to visibly squirm about even while standing.

Katherine pointed out, "Well, why is it that Alan has the right to tell you what to wear, but not me? Aren't I just as much a member of the family?"

"Of course you are, my sweet Angel," Susan replied.

"And he is the new man of the house, right?"

"Certainly." Susan loved this kind of talk.

"And you and I, we're his personal cocksuckers, fully dedicated to keeping his cock stiff and throbbing with pleasure as much as possible, aren't we?"

"Of course!"

"Well then, what he says goes, and our duty is to obey. And serve! Right, Mom?"

Susan's chest was heaving, she was suddenly so excited by those words. "Right!"

Katherine turned to her brother. "So, Bro, that means you now have total control over my wardrobe. Toooootal controoool..." She said those two words extra slowly, loving the sound of them.

Susan gazed off in the distance, silently mouthing those same two words as her lust increased. "Total control." His control over us is total! It's absolute! What's happening this morning is how it's going to be around here from now on. It's less about eating and getting ready for school and more about lovingly serving his dominating cock! Together!

But her train of thought was interrupted when she heard her daughter ask, "BIG Brother, what do you want me to wear today?"

"What you've got on," he replied.

Katherine smirked and giggled.

Somehow, that just turned Susan on even more. She loved to be sexually "outsmarted" these days. "Darn it! You've got me there, both of you. It just goes to show - yet again! - that there's no resisting Tiger or his fat cock. But Angel, since I can't get you to change, I'm curious. Doesn't that tiny strap of fabric ride up into your pussy and ass?"

Katherine's mood improved when she stood up and showed off her outfit. "It sure does! Just about any move I make causes it to go up there. I can practically get myself off just by shrugging my shoulders repeatedly. And it's so tight that if I sit down it nearly cuts me in two." She shuddered momentarily as she drew a deep breath. "It's great!"

Her pussy was overly sensitive at the moment, but she helpfully demonstrated what she meant anyway. She used a hand to lift a shoulder strap up and down, causing her to moan in delight as the fabric pressed and moved against her pussy lips and clit.

Susan complained, "Really, Angel, that's too much. It's so improper. Whatever will I do with you and your crazy outfit? And in front of your own brother!"

Susan realized as she said this that in fact she was really trying to stimulate Alan with the things she was saying, rather than actually discouraging Katherine from wearing such an outfit.

By this point, everyone recognized her charade in saying things like "And in front of your own brother!" But it was still fun for everyone, helping to make their actions seem naughtier and more arousing.

"Mom, you really should try it. The fabric would be even more deliciously tight all over if it crossed over your even bigger hooters."

"I don't know. Maybe I'll try it just once or twice. Just to see what kind of mischief you've been getting into, mind you. And by the way, let's not use vulgar language like 'hooters' - the proper term is 'jugs.'"

Everyone laughed at that. Susan had always been up tight on sexual topics, but her recent practice of letting loose sexually had changed her demeanor. Now she was making jokes about sex and sexuality for practically the first time in her life.

Katherine happily agreed. "Try it anytime, Mom. Or, even better, should I ask Aunt Suzy to pick one up for you next time she's at the store?"

"I can ask her myself, thank you very much," Susan said in an authoritative tone, indicating that her somewhat hypocritical chastisement of Katherine's outfit just a minute or two before had already been forgotten. Susan definitely wanted one of those bathing suits - she allowed her pussy to do her thinking about it, and her pussy very much liked the idea of having the strap ride up and rub around all day.

"The only problem with them is that the straps are so hard to keep in place," Katherine added with mock dismay. She then ostentatiously slipped one strap off a nipple, then slipped the other strap off her breast altogether.

Alan's penis had started becoming flaccid after Katherine stopped stroking it, to give him a strategic break, but it surged back to full size when he saw that.

With Alan and Susan raptly attentive, Katherine moved the strap that vainly attempted to cover her pussy to the side. Still on her feet, she moved back from the counter as she did this so that Susan could better see what she was doing. She knew that she was making her mother horny, even if Susan wouldn't admit her lesbian desires to herself.

Katherine thought to herself, Aunt Suzy was so right last night when she said it's more arousing to be partially dressed. Look at me; I'm the center of attention because of this bathing suit!

"Look, Big Boner Brother!" she said with even more anguish in her voice. "All my straps are coming undone! Woe is me!"

Alan joked, "You know, you really should cover your tits and your pussy with your hands, before you catch a cold from the draft." His erection was poking straight up in his lap, but he wasn't asking for help with it just yet since he sensed he still needed his strategic break.

Katherine smiled. "Good idea." She stuck a finger into her pussy while using her other hand to fondle a tit.

Susan said to her, "Katherine, I think Tiger sees your vulgar display well enough. Please take your hand out of your private place and try to control yourself for at least a few minutes."

However, this was said without much conviction, as she was growing more aroused with each passing moment. She was also being extremely hypocritical, since she'd been masturbating herself in open view mere minutes before. But she wasn't thinking clearly; instead she was reacting without real thought to how hot and bothered Katherine was making her.

She pretended not to see the fluids dripping from her daughter's pussy and running down her leg. (If she had, she would have felt obliged to ask Katherine to clean up.)

"I'm just trying to put the straps back into place," Katherine falsely claimed.

"Sure you are," her mother replied in a tsk-tsk voice. "The way you're acting, you might as well not bother with clothes at all. Then you could just keep your finger permanently in your pussy."

"Oh goody! Is that a request or just a suggestion?" Katherine joked.

"Neither."

Everyone laughed at that exchange, even Susan. Then she went on more seriously, "As fun as it all is, Angel, we can't just sit around and masturbate for each other all day, or we'll never get you two to school. Don't you think you should go sit back down and tend, er, I mean, keep your brother company?"

Susan's problem was that she was bothered greatly because her son's erection wasn't being attended. In her book that was now the most important duty of whatever women happened to be present. In addition, she was eager to share licking his cock with her daughter for the very first time.

Katherine sat back down and immediately took Alan's dick in hand. "Mom, I think you did mean 'tend.' And look: he's still erect!"

Susan came around the counter to take a look. She smiled approvingly when she saw Katherine resume jacking him off. She muttered quietly to herself, "That's better. That darn strategic break was really bugging me." Then she said out loud, "Very good, Angel. Remember what Nurse Akami said."

Before she could continue, Katherine said, "I know: it's not just quantity of his orgasms; it's the quality. He needs prolonged, highly satisfying stimulation for each and every one of his six daily cums."

"Well put," Susan said. "Let me finish up here in the kitchen and then I'll be able to help. Tiger, what do you think about having two mouths on your cock? Would you call that 'prolonged, highly satisfying stimulation?'"

"You know it, Mom! I can't wait!"

Susan obviously had no problem with Katherine fondling Alan, but the same couldn't be said about Alan fondling Katherine. So he waited until Susan was back in the kitchen and busy working there before he resumed fingering his sister's slit.

Between jacking off her brother and getting secretly fingered, Katherine couldn't have been happier. Watching Susan puttering around in the kitchen in her useless erotic 'apron' was the icing on the cake. After a while, she quietly moaned to Alan, teasing him, "Mmmm, I know something I'd rather have in my pussy than your finger." While Alan continued to frig her, she snickered and added, "Not that there's a finger in there now."

"What's that, dear?" Susan asked from the kitchen. She was only able to hear them muttering.

Katherine now teased her mother. "Hmmm. I'm talking about something near and dear to me. I'll give you a clue. It's long and hard and throbbing. My hand is slowly pumping up and down it, and I totally love it! Right now it looks like it's aching to fill a hole."

"Oh, does it?" Susan replied happily, glad to get confirmation that Alan's cock was being well tended. She picked up a bottle of maple syrup with a narrow neck and began unconsciously stroking the neck like she was jacking it off.

Then she remembered that they weren't supposed to tease each other about fucking. "I meant, uh, Angel, it's not right to think of such things. Besides, I'm sure Tiger wouldn't want to stick his red hot poker in his sister's or his mother's hungry hole, so you must be speaking of something else."

Susan bent over forward as she said this, spreading her legs widely so Alan could see clearly the hole that she was referring to.

Katherine moaned, "Mmmm. 'Red hot poker'. I like that. What do you think of that, Big Red Hot Poker Brother?"

Most other guys would have lost it, jumping up and fucking someone by this point, but Alan had grown used to this level of teasing so he just enjoyed the scene. However, he did complain, "Mom, you said no teasing about my fucking you."

"Oh, sorry baby. I was actually trying to discourage Angel from that kind of talk, but it came out the wrong way. I don't know what's gotten into me today. I must still be excited from last night. I get so hot when I think about how you tamed Amy and added her to your stable of big-titted hotties."

She reluctantly went back to working in the kitchen. She was mostly marking time until breakfast was over, so they could start the dual blowjob. Even so, she was more intent on flashing her bare breasts and ass than getting anything done, so once again her apron ended up hanging in a very precarious position because the straps had slid down her arms.

Katherine giggled as she stroked, "I know what I'd LIKE to get into me today, Mom. Do you know what I mean when I say INTO me?"

Susan spun around, trying to be more take-charge. "Katherine Plummer! You stop that kind of talk this instant!"

Katherine pretended innocence. "What? I was talking about sucking his cock, not fucking."

"Oh. I suppose that's okay." Susan went back to the sink even though she suspected (correctly) that Katherine had really meant another hole.

Katherine decided to run with her new meaning. "Yes, it's true that I have a big, fat brother-cock in my hand right now, but what it really needs is a warm, wet mouth. A sexy sister's sweet sliding lips! Her needy tongue flitting around someone's super-sensitive sweet spot while her lips relentlessly slide up and down, up and down, up and down! Kind of like how my hand is pumping up and down, up and down, up and down right now!"

Susan had started washing the dishes, but upon hearing Katherine talk like that, she fell into a kind of fugue. Staring blankly into space, she began stroking the long cleaning brush she was holding.

Emboldened by what she saw her mother doing to the brush, Katherine went on, "But I'm being too selfish, aren't I? I'm my brother's fuck toy, and fuck toys share. Mom, I think he needs your warm, wet mouth too! But do you think just one mouth is enough? I think not! I can't wait until we're both slurping and sucking and loving and licking it at the same time!"

Susan was slowly bringing the cleaning brush up to her mouth, but at the last second she realized what she actually held in her hand. Even that didn't totally deter her as she moaned erotically, "Oh! YES!"

Katherine's words were having an effect on herself as well. One hand pumped faster and faster over the top half of her brother's boner, while she reached between his legs with the other, moving towards his anus. She didn't insert a finger into it, but instead just caressed his perineum, the area between his anus and his balls, which was highly stimulating.

Alan complained, "Mom, make her stop. I have to eat some food every now and then or I'll die of starvation, but I can't do anything but clench my PC muscle while she's doing that. Death by sexy teasing!"
