Spacer X Stories: Part 63

REASONABLE BOUNDS
Chapter 63

After that rather bizarre breakfast finished, I took a shower, dressed, and got busy with my writing. Fortunately, for both my work and sanity, I didn't see the girls for the rest of the morning.

We all got together for lunch. However, the two hellions were dressed on the conservative side, and acted that way as well (aside from making several jokes about needing my 'special sauce' on their food). They weren't particularly friendly or unfriendly, but mostly seemed distracted. They made a few veiled hints about a 'big project' they'd spent the morning working on. Whatever it was, it was obviously taking up most of their attention. Even as we ate, I could tell that new ideas about their project were coming to them, ideas they wanted to share but couldn't because I was there. There was a lot of furtive whispering though.

They also had a habit of humming 'The Imperial March' whenever I walked to or from the kitchen. That's the tune played almost every time Darth Vader appeared in the Star Wars movies. It was amusing - the first couple of times.

Still, overall, it was kind of nice to have things back to the 'old ways,' where they more or less dressed and behaved like ordinary teenage girls, rather than sex crazed nymphomaniacs desperate to drain my life force out of me through my penis. I needed a break to absorb all the tectonic changes that had happened recently, plus time to catch up on my writing.

At the end of the meal, I got their full attention and made an announcement. I reminded them about Nicky's plans to come home soon, and then explained how Mindy and I had come up with a scheme to divert Nicky to Hawaii for the next two weeks.

My vixen daughters appeared both amused and relieved. Michelle snickered, "Looks like the shoe's on the other foot - now YOU get to be the schemer!"

I pointed out, "However, Nicky's not going directly there. She's driving home tomorrow. She'll be spending the night, as she has some last minute errands, and of course she has to pack for tropical weather." (Even though Nicky was off at college, her bedroom was more or less unchanged, and she still had a majority of her clothes and other possessions in there.)

We discussed the problems of Nicky being here, even if only for one night. I made it clear that there would be a total sex ban during that time, and there shouldn't be even the tiniest hint about something sexual going on.

Michelle pointed out, "But that's no problem. We've got our sex boycott going on anyway, so the timing is perfect. Besides, we'll be totally busy with our project, not to mention our crap job. We'll hardly have a chance to see her anyway."

I said, "You mean your video job, not your 'crap job.'"

She rolled her eyes. "Whatever."

I repeated myself a bit, stressing the importance of not giving Nicky any chance to figure out what was going on. I even did some finger wagging and pointing to emphasize my concerns.

That led Ruby to ask, "But she's only gonna be in Hawaii for two weeks. What then?"

I really hated that question, because I had no answer. I admitted, "I honestly don't know. She's at school most of the year, obviously. Maybe we'll just have to cool down and be very discreet until she goes back north. I dunno. At least, we'll have two weeks to talk about it and come up with a plan."

"That's unacceptable!" Michelle complained. "I have no doubt you'll come to your senses about this dating stinky boys thing. Eventually. Even though you can be as slow and as stubborn as a mule when it comes to changing your misguided ways. So that means we'll have to go without pleasuring the King for the ENTIRE summer? I SO don't fucking think so!" She folded her arms underneath her rack to emphasize her point (not to mention bolster her humongous tits!).

Ruby turned to Michelle and said, "You mean get by with less pleasuring. Like, we may only get to suck on the King once or twice a day. We could sneak out of the house or something. But not go without completely! Come on. That's just crazy talk!"

Michelle's eyes went wide. "Oh GOD! What if Daddy doesn't give in for THE ENTIRE TWO WEEKS, and then Nicky comes back?!"

Ruby put a hand on Michelle's arm, as she clutched her for support. "Don't even go there! You're scaring me!"

I said, "Let's not 'go there' for now. But be warned. I'm willing to go to some pretty extreme lengths to keep Nicky out of our sordid little harem world. So let me know if you have any ideas."

Soon, we headed back to our respective rooms upstairs. I was glad to see that they were no longer insisting on locking themselves away and were back to acting relatively normally around me (except for them singing or humming the 'Imperial March' tune whenever they saw me). That made the sex boycott a lot more bearable.

A couple of hours later, I decided it was a good time for me to take an extended break. I went to a nearby sex shop, and bought a variety of sex toys, clothes, and other items. I'd been thinking about making such a trip for a while, and I'd compiled quite a long want list of things to use on, or give to, my lovely ladies. I probably should have waited until after Nicky had come and gone, but I have to admit that my sexual enthusiasm got the best of me. Most of the purchases I hid away very carefully, because I wasn't going to need them for a while (and I certainly didn't want Nicky to see them!). But there was one set of matching items I'd bought that I planned on showing off almost immediately.

Still dressed in my usual clothes, I went down the hall and knocked on Michelle's door.

"Don't come in, Daddy!" Michelle shouted through the door. "We're working on our big project, and you're not allowed to see it until it's ready."

I was pleased at how quickly Michelle had gone back to leaving her door unlocked. (Either that, or they'd noticed from yesterday that locking it was a futile gesture.) I said, "Okay, fine. I don't need to go in, but the two of you need to come out. Both of you, report to my room immediately. Naked!"

Ruby said, "But Daddy! You know about the sex ban!"

"Yeah!" Michelle agreed emphatically.

I told them, "Don't worry, you won't be doing anything special with my penis. But both of you need to show up completely nude, because it's time for your daily spanking. So long as you're obedient and don't misbehave, you WILL be spanked. You know the drill."

There was a long pause, and then a nervous Michelle asked shyly, "Position number two, followed by position number one?"

"That's right. Oh, and I want both of you to crawl on all fours to my room before assuming any position. That'll be part of the spanking tradition from now on. And the longer you take to start crawling, the more spanks you'll get."

"Oh shit!" I heard one of them mutter. I lingered by the door long enough to hear the rustling sounds indicating they were following orders.

Then I stood in the middle of my room. I made sure my door was wide open, and I was standing in a spot where I could see Michelle's door all the way at the other end of the hall.

I didn't have to wait long. I'd only just found the perfect spot to stand in when I saw Michelle's door open a little bit. Her head peeked out at shoulder level. But then she made eye contact with me, and her head disappeared again. Seconds later, the door opened all the way, and her absolutely incredible nude body appeared in full. Then she started crawling down the hall with her head bowed. Ruby followed right behind her.

My penis was half-hard from anticipation, and grew fully hard as soon as I saw Michelle's embarrassed face and her drooping tits swinging wildly underneath her. I unzipped my fly, and let my erection out. I thought, This is awesome! Sex boycott or not, I need to find more excuses to get these two naked. I know, the general rule is that it's sexier if a woman wears at least some clothes. But that rule is more for normal women. These two are like goddesses! Their perfect bodies are works of art that demand to be seen in their entirety!

Michelle heard the zipping sound all the way down the hall, and looked up with concern. Seeing my engorging penis, she frowned and dropped her head back down, and then kept crawling. Obviously, she was worried about maintaining her sex boycott in the face of such temptation.

I noticed that, as she crawled, she wasn't avoiding letting her nipples rub against the carpet. In fact, at times, she seemed to deliberately lower herself just to let them roughly brush against it. From the look on her face, I could only imagine the kind of sensations she was feeling from letting her nipples stroke the carpet like that as she crawled towards me. It looked like she was shivering with delight every time. At one point, she even had to stop and bite her lip with her eyes closed before she could continue crawling towards me.

Jesus H. Christ on a pogo stick! It occurred to me, How many girls her age would be so endowed to even have the problem of nipples dragging on the carpet?! Not even Ruby was quite that busty, not unless she slouched down as she crawled. She lacked the jutting factor.

I can't tell you how much fun I was having watching them crawl to me. I started stroking my erection to enjoy it all the more. The only problem was that I could only really see Michelle, since she was in front. I quickly fixed that by saying, "Hey! You two crawl side by side so I can see you both. Since we have wide hallways, we should put them to good use."

So that's what they did (although Michelle had to take the lead again while they crawled through my doorway).

Was it wrong to have my own daughters crawl to me naked, just because I felt like it? Okay, maybe. Well, to be honest, 'hell yeah!' is more accurate. But the way I looked at it, they had freely, eagerly, and pretty much unilaterally declared themselves my cock slaves. As part of that, they said they would do anything to make me feel good, and this made me feel very good. Besides, I knew they were feeling terribly ashamed, but they both loved that. Humiliating and submissive acts aroused them like nothing else.

What can I say? My morals were crumbling by the day, or even by the hour. But, as the saying goes, if you're going to hell in a bucket, you might as well enjoy the ride.

They crawled all the way to my feet. Both of them actually tenderly kissed my feet, which was a pleasant surprise. Then they stood up and assumed position number two (hands on head, legs spread wide, and chest thrust out) side by side a few feet away from me. They stood up and stared straight ahead into space, even though both of them had certainly noticed the way I was stoking myself.

Neither of them seemed put out having to do this during their 'sex boycott.' In fact, they were positively enthusiastic, and bursting with life and energy.

Michelle asked, "Daddy? Permission to speak?"

"No. In a situation like this, you should call me 'Master.'"

I could see both of them shiver with arousal, simply from being denied a chance to speak.

A long pause followed, where I simply closely examined them. I could tell this really aroused them, and they tried their best to strike especially seductive poses. They mostly stared blankly straight ahead, like they were trying to be mannequins. Occasionally, they couldn't resist, and they briefly glanced at my face or down at my stiff erection poking straight out.

Finally, Michelle asked again, "Master? Now can I speak?"

"Sure. What is it?"

"I'd like to lodge a protest. It's about this whole crawling thing. Ruby and I agree that it's... um... it's far too arousing."

Ruby looked at me and nodded, and then went back to her frozen, stare-straight-ahead stance.

In feigned ignorance, I asked, "Arousing? How could that be bad?"

Michelle explained, "Well, first of all, we're in the middle of a sex boycott, and this violates the spirit of that. You're using our sexy, naked bodies to get yourself aroused." She nodded at my stroking hands.

"This is true," I brazenly agreed. "Consider yourself lucky I'm not doing more with your sexy bodies, but I'm willing to tolerate your boycott - for now. Do you have anything else to complain about?"

Michelle was surprised by that answer, and didn't quite know how to respond.

But Ruby said, "I see a problem, Master. You're spanking us to punish us, right? So we should be hating it, right? But the act of crawling across the house - with you watching the whole way, no less - has gotten me so terribly horny that I can hardly breathe! And the spanking hasn't even started yet!"

I deliberately acted stupid, and looked confused.

Michelle saw that, and explained, "Da- er, Master, when we get really horny, we obviously see that as a reward. And when we're spanked really hard, we see that as a punishment. But if you make us crawl to our spankings, pretty soon we're gonna mentally tie the two things together. Then everything will get all confused together. Before long, whenever you make us crawl, we'll think about being spanked! And when you spank us, we'll think about crawling! We're both gonna be, well, we'll be constantly horny!"

Ruby nodded emphatically, which did impressively delightful things to her chest, and added, "And we'll be constantly longing to suck on your fat fuck stick! Uh, Master!"

I replied as if unconcerned by such worries. "I don't see a problem with all that. I'm assuming that this boycott is an aberration, and most of the time, you'll be more or less good. I plan to spank you daily, or close to it, so the vast majority of spankings will be purely sexual. I want you to associate that with arousal, so I'm really not seeing anything wrong here. Like I said, when you're obedient and well behaved, you will be spanked. This is not intended to be a punishment, but rather a reward. And depending on how well behaved and obedient you are, taking your spankings may be an intensely sexual and extremely pleasurable reward. The way I see it, there is absolutely no reason at all for you NOT to be excruciatingly aroused when you crawl to me to naked and beg to be spanked."

Michelle was suddenly gulping for air. "Oh! Oh God! Are you really going to spank us that much?" She was suddenly so turned on that she was having a hard time keeping her hands on her head. She was doing a great job of keeping her tits thrust out though, even as they were heaving about wildly.

"Of course," I said matter-of-factly. "I own you."

I wished I had a camera ready to capture the dumbfounded look Michelle and Ruby exchanged between themselves. They both sucked in a huge breath at the exact same time, which had the lovely side effect of collapsing their stomachs and thrusting their huge bouncy melons forward.

I picked up a ping pong paddle I had left on top of an end table. "I own you both, in the exact same way I own this paddle." I put the paddle back down, so I could go back to jacking off. "If it pleases me to frequently spank you, to constantly remind you that you are my sex slaves, that my domination of you is total and absolute, that your chief duty as my slaves is to keep me endlessly aroused and entertained, that, in fact, you have no free will... if it pleases me to remind you of all that, then why shouldn't I?"

Michelle gasped lustily. "Oh God!" Her whole body was shaking with desire.

Ruby was shaking too, maybe even more than Michelle. She asked, "Master? Permission to touch myself?"

"You're already touching your hands to the top of your head," I pointed out, deliberately playing the fool again.

"No!" she said in frustration. "I don't mean that. I mean... down below!"

"Where? Your toes?"

"Not that far down!" she gasped desperately.

Michelle exclaimed, "She wants to touch her CUNT! Her hot, hot, burning hot cunt! I do too!"

As I kept on stroking myself, I said firmly, "Absolutely not. You're in the middle of a sex boycott. If you do that, you'll get so horny that you'll be unable to resist anything I tell you to do."

Ruby panted, "But we're that horny already!" She looked at Michelle, and hastily added, "Well, almost."

I said, "Almost. You see? That's the difference. One point, though. Remember that there are two kinds of spankings. There's the spankings you'll get when you've been good. We can call them good spankings. And then there's the spankings you'll get when you've been bad. Obviously, those are the bad spankings, and those will be much more painful. You both have felt those. Do you want more bad spankings?"

They both shook their heads fiercely at this, which set their big tits swaying again very nicely.

Michelle raised a hand like a shy student, which also did wonderful things to her body, and to her chest in particular. "Master? I worry. I'm worried it could easily get to the point where I find spankings so arousing, I'll even look forward to the bad ones."

"Perhaps. But remember you can have one or the other, but not both on the same day. Besides, I can also resort to the love tap type spanking. Do you remember that?"

She shuddered with disgust. "How could I not? That was more traumatic and painful than the worst whipping! Never again! Please! My body craves to be spanked and dominated, and that just makes a mockery out of all I hold dear!"

I grinned. As a parent, it was damn near impossible to find any methods to control her, and now it looked like I had a very good one. I quickly suppressed my grin, trying not to show just how happy that made me. I casually asked, "Now, who wants to be spanked first?"

Neither of them said anything, and neither one looked at all eager.

I was glad to see this, because it confirmed my feeling that Michelle felt her spanking yesterday was a punishment, and not a reward. I'd been worried that she would enjoy even the harshest spankings I could muster.

Finally, Ruby asked, "Master? Will this be a good spanking or a bad one?"

I replied, "We'll see. You both are at my complete and utter mercy, so it'll be whatever I feel like."

"Oh God!" Ruby muttered. I could see her legs start to give way as her knees buckled out from under her. But she caught herself just in time and managed to right herself.

Michelle's entire body swayed back, like she'd nearly been blown over by a powerful wind.

Needless to say, they both found my attitude to be extremely arousing.

"Hmmm," I said. "I don't want to be seen as choosing favorites, so we'll use the 'eeny, meeny, miny, moe' method." And that's exactly what I did.

By chance, I picked Michelle. I said to Ruby, "You'll be first tomorrow." Then I picked up my paddle and sat down on the edge of my bed.

Michelle finally took her hands off her head while Ruby remained in the number two position. Pointing at my erection, Michelle said with worry, "I hope you know I'm not going to do anything with THAT."

"I wouldn't dream of it," I replied. I patted my lap. "Now, bring your hard, sexy body over here."

As Michelle laid herself over my legs she said, "Master? Can I ask you a favor? Look at my ass."

I knew she was going to say more, but I hastily cut in, "With pleasure." I ran a hand up and down her ass cheeks.

"No!" she complained. "Ow! Owww! Don't... See? Don't- OW! Hold on, please!"

I'd only been lightly stroking her ass, but I stopped.

She calmed herself, and said, "See? That's the favor. You spanked me so hard yesterday that my butt still hurts really bad. Same with Ruby. Show him."

Ruby turned around and bent over a bit, putting on a great show while keeping her hands on her head. It was hard not to notice just how red her ass was, as was Michelle's.

I joked, "My goodness, Ruby. That looks painful. But I think I'm going to have to keep your ass that color all the time from now on, just so I can always say you have a Ruby red ass."

Ruby turned back around and frowned at me. "Ha, ha. I'm not amused."

"But what if I'm not joking? What if I really will keep your ass constantly red and well spanked? What if, from now on, you'll always have trouble sitting or lying down, because your ass will always be freshly spanked?"

"Oh gawwwd!" She brought her hands down from the top of her head.

But before her hands could reach her pussy, I said, "HEY! Stop that!"

Her hands froze in mid-air, less than a foot from their desired target. She kept them there like that as she begged, "Please! Pleeeaaase, Master! Just let me touch my clit. Just for a second!"

"Sorry, but no." I stared hard at her until she brought her hands back up to her head. "Now, Michelle, you were saying?"

Michelle's eyes were bugging out, as she obviously was contemplating a constantly red and sore ass. Her hips were wiggling wildly in my lap.

I gave her some time to recover her breathing. I looked up at Ruby, and at first I thought she was dancing. But no, she was trying her best to stand still with her hands on top of her head, but her body was simply too aroused. Her hips in particular couldn't stop gyrating.

I said to Shelle, "Now, I feel like playing with your pussy for a little bit. Just 'cos it's right there, and it looks and smells so good. But you are NOT allowed to cum while I'm doing that. Period! After all, you're having your sex boycott, which means no cumming. Right?"

Shelle groaned loudly, and so erotically that I was half-convinced she was cumming already. But she kept wiggling, and said, "Daddy! That's just so cruel. But, but... I'll try." She shut her eyes tightly, and clenched her teeth, obviously steeling herself for my fingers.

I slid two fingers into a very, very soaked slit. I couldn't go far due to her hymen, but I pushed in as far as I dared. Seeing how hard she was trying not to climax, I mostly just kept them there. I said, "You know, girls, given how you both said you've had lots of sex with each other, and with other girls, I'm fairly amazed you've both managed to keep your hymens. There must have been all kinds of dildos and strap-ons floating around."

Michelle grunted, "Ruby! Answer!" Obviously, she figured she was in no condition to talk just yet.

Ruby wasn't much better, but she said, "Hell, yeah, that was a struggle! A constant struggle. That's another reason I can't wait for you to fuck me, just so I can finally get rid of that damn thing!" She wiggled and gyrated slightly as she fought a losing battle to stay still. "There were all kinds of... I could tell you stories. ... Close calls!" She closed her eyes and tried to recover her breath. "But... it just shows... how much we fought... to keep... biggest prize... virginity... just for you!"

"Yes!" Michelle grunted, glad that Ruby had apparently said what she wanted said.

Finally, I asked Michelle, "So, you said something about a favor?"

She grunted through clenched teeth. "Yes. Look, look... at my ass, and then look... at... Ruby's."

After I gave an approving nod, Ruby turned around and bent over. She spread her legs straight and wide and clenched her ankles.

Michelle commented, "See? That's the favor I wanted to ask. Look how my ass is even redder than hers, 'cos you spanked me even longer than her."

"Wow, that's true," I replied while starting to move my fingers inside her pussy a little bit. "Boy, that was an easy favor to grant. To be honest, I was looking at your ass anyway. I'll just have to look at it some more." I ran my other hand all over her reddish ass cheeks. "Now-"

"Wait!" she complained. "Don't be funny! This is serious. Can you please not spank me so hard, or so much? My ass can't take any more!"

"Okay, fine," I replied. "I'm not cruel. I won't spank you nearly as hard as yesterday, okay? And I'll use my hand instead of the paddle."

"Thanks! You're the best! I love you, Daddy!"

I gave in easily on that point, because I knew that even a mild spanking would hurt her tremendously, after what she'd experienced the day before. Plus, I preferred using my hand, so I could fondle freely between spanks without the hassle of having to hold the paddle or always pick it up and put it back down.

So I began to spank her. Ruby, I noticed, was still bending over lewdly right in front of me.

Michelle immediately said her line: "One! Thank you, Master! May I please have another?"

But instead of immediately continuing, I squeezed two fingers into her very tight and wet pussy.

She moaned sexily, "What are you- UH! OH! God! Daddy! Hnnng! Daddy?! What are you doing?!"

I pointed out, "This spanking is gonna hurt you a hell of a lot. I'm trying to counter the pain with some pleasure. That way, you'll be able to keep going longer." Then, before she could question that logic, I hit her with the second spank.

"UGGH! Two! Thank you, Master! May I please have another?"

I poked in and out of her sopping pussy a couple of times, just to keep her off balance, and then I slapped her ass again.

"AAAAIIIIEEE! It hurts! God, it hurts so bad! Uh, three! Thank you, Master. May I please have another?"

As my fingers played inside her pussy, I said, "Good cock slaves don't complain. Now, I know you're hurting, but try to hold out as long as you can before you gripe about it. Okay?"

I saw her head nod, and heard a tiny, "'kay."

My hand went down again, and her head went up as her whole body reacted with a jerk. But she didn't scream this time. Instead, she hissed through clenched teeth, "Four. Thank you, Master. May I please have another?"

I continued to eleven like that. The spanks came fairly infrequently, and I spent a whole lot more time playing with her pussy and engorged clit. I also reached under her and played with her nipples and tits as much as I liked. As much as my girl wanted to cum (and cum HARD!), she rode the edge of orgasm admirably well, for one so inexperienced in doing so, while enduring the teasing touches of my fingertips on her helplessly exposed body.

I knew that Ruby was determined to remain bent over until I told her to stand up. I wanted to see just how long she'd be able to hold out from watching the spanking, but she started to wobble in an increasingly unstable manner, and I didn't want her to fall over and possibly hurt herself. So after the fifth spank, I let her resume her previous hands on head position. She did so, but stood even closer to get a better view of the spanking. I could have reached out and touched her pussy, she was so close.

As the spanks continued, I kept mentioning to Michelle that she wasn't allowed to cum until I said so. I guessed that she was cumming from time to time, but trying her best not to, and attempting to hide it when she did. Upon the eleventh spank, she shuddered so obviously and moaned so erotically that it couldn't be denied she'd just climaxed hard. Then her body went completely limp as I continued to play with her tits and pussy at will. I was avoiding her ass by this point though (well, except for the spanks!), because any touch there hurt her.

To be honest, I didn't really mind all that much that Michelle had cum without permission. For one thing, it gave me something to 'train' her on, which I was already looking forward to. If she were anything like her mother, she'd take like a duck to water in learning how to delay the full power of her orgasms so as to heighten the pleasure she'd ultimately experience.

I'd more or less forgotten Ruby was standing there after she'd stood back up, despite her oh-so-sexy pose. I glanced up, and caught her with one hand on her head, but the other one fingering her pussy. Seeing that I was looking her way, she put that hand back on her head in a flash. But she blushed, knowing that she'd been busted.

I asked, "Ruby, just what do you think you're doing?"

"I'm sorry, Master! It's just all too... arousing! I can't help myself!"

"Try harder," I said dispassionately. "That means five extra spanks for you."

"Oh shit!"

I looked back down at Michelle's cherry red ass. It was wiggling quite noticeably. She'd also lifted it up as much as she could, which was quite an accomplishment given her semi-delirious state. "What do you think you're doing?" I asked her.

"I'm sorry, but I can't help myself either! Please! Spank me more! I need it!"

This surprised me. I asked, "Doesn't it hurt a hell of a lot?"

"It does, but I need it so bad!"

She was panting so hard I could barely understand her.

As my fingers twirled over her clit and I yanked on a nipple, I said, "I don't understand. I'm not going to spank you any more until you explain yourself."

She panted, "Please! Please! Stop... playing with me... long enough... so I can, can talk! ... Can't..."

"Nope. Sorry," I replied, figuring she was saying something about wanting to calm down enough so she could talk clearly again. "I'm having too much fun. Since you and Ruby are like-minded, maybe Ruby can explain for you."

Ruby was doing better, now that her hands were back on her head and she couldn't masturbate. She had her eyes closed too, to help cut down on the mental stimulation. She said, "I can try, Master. First off, I think you're giving her such a constant stream of pleasure with all your fondling, that the spanks actually feel good. It's like when you exercise hard, and then your muscles 'hurt so good' afterwards."

Michelle grunted loudly in obvious agreement.

Ruby continued, "But more than that, I think it's the way you're proving your TOTAL DOMINATION over us!"

"UUURRRRNNNGGGH!" Michelle agreed. Her body jerked up like her back had snapped. But really, it was just that she was having another orgasm.

Ruby opened her eyes and panted excitedly, "We TALK about being nothing but your sex toys, your big-titted slave daughters, but here you're really SHOWING it and PROVING it! Michelle is obviously completely helpless! You OWN her! You own her body, every last Daddy-loving inch of it! You're playing her like a fiddle! Look at her, writhing in heat, desperate for your cock! Aren't you, Michelle? Wouldn't you love to vigorously suck on his FAT COCK all day long?"

Michelle nodded her head up and down, nearly violently so.

Ruby continued, "But the King is under her, so close, yet oh so far! It must be torture for her, but it just proves all over again how helpless we are! You're mocking her! Mocking her! Rub your cock against her tummy and mock her even more!"

I said quietly, "I won't do that. I don't want to do something that'll violate the rules of your boycott. But, Shelle, if you're so desperate for my cock, pretend my fingers are the King." I shoved three clumped-together fingers into her mouth.

She immediately began sucking on them and licking them with a fevered passion.

It was so intense, my desire to cum grew greatly, like she really was working on my erection. And I'd never realized just how many pleasure nerves there are in a human hand. It was like she'd discovered a whole new erogenous zone.

I said to her, "I know you can't talk at the moment, but I want to know how many times you've cum already. Don't try to deny it. Remember that I'm your Daddy-Master, and there's nothing worse than lying to me. Since your mouth is full, use your fingers."

She raised up five fingers.

"Five? Hmmm. That's more than I thought."

But she shook her head a bit, and brought her hand back up with just one finger pointing out.

"Six?"

She shyly nodded.

"Shelle, you've been a bad, bad, girl. I'm going to spank you two more times for each time you came. And if you cum any more, that'll be three more spanks for each time. Understood?"

She nodded, but then she shook her head and mumbled a bit, making it clear she wanted me to take my fingers out of her mouth so she could talk.

As soon as I did, she said, "But Daddy! That could be a vicious circle! I'm so hot, I'm gonna keep cumming, and that'll mean you have to spank me more, and that'll mean more climaxes, and we'll just keep spanking and cumming forever and ever!"

I replied calmly, "Well then, you'll just have to redouble your efforts not to cum. Good sex slaves cum exactly when their Master tells them to, and not one moment before."

"Oh gawwwd!" Michelle and Ruby both moaned erotically in tandem.

I resumed the spanking. I alternated between playing with Shelle's tits, clit, pussy, and mouth. The problem was, I didn't have enough hands to do all at once. Because of her hymen, I mostly just slid my fingers all over her wet pussy lips and her exposed and throbbing clit. I didn't want to risk ripping her hymen when she was writhing around so much.

Somehow, she managed to keep crying out her "Thank you, Master. May I please have another?" line after each spank. But she was so far gone that often I could barely understand her, especially since she oftentimes ended up shrieking it. And with my hand going to and from her face between most spanks, I eventually happened to feel the tears pouring down her face. She was obviously suffering greatly, but she was being a trooper in not screaming more than she did. She also was doing her damnedest not to cum. She constantly moaned and groaned and even screamed so much, even when I wasn't spanking her, that if one had just been listening, they might have thought I was sawing her in half.

We got to twenty-two spanks, just one shy of how many she was to get if she didn't cum any more. Upon the twenty-second slap, she cried out like she'd just been split in two. Her entire body somehow lifted off mine, even if only for a fraction of a second. Obviously, she was having the mother of all orgasms.

And then she simply collapsed in my lap. Her body went so limp, that I was obliged to check her pulse to make sure she was okay. She didn't pass out, not quite, but she drifted in and out of consciousness. And she stayed like that, with her eyes glassy and her body like a wet noodle.

Technically, she was owed four more spanks (one still to go, plus three more for the climax she'd just had). But I was forced to end her spanking, since I doubt she even would have known what I was doing if I kept going.

But my spanking duties weren't done. I lifted her up and rested her on the bed behind me, and then Ruby took her place on my lap.

Ruby was so excited and aroused, her entire body was shaking before I even started.

Funnily enough, the exact same sequence repeated itself, almost to a tee. Except with Ruby, she started out even more aroused than Michelle had (if such a thing was possible!), so she was reduced to a quivering, orgasmic blob of jelly even faster. She too valiantly fought the urge to climax, but it was a losing battle, and she had five big ones. Of course, that meant more spanks, using the same formula as before (never mind that I hadn't told her how many I was going to give her in the first place! Neither of us were thinking that clearly by this point).

After about Ruby's tenth spank, Michelle recovered enough to get off the bed and come around to witness the rest of the action. She was in no condition to stand, but managed to plop herself into a nearby chair and watch from there. I noticed that she conspicuously arranged herself so as to not be sitting on her inflamed buttocks and was instead half-lying down with her hips turned to one side and her upper body draped along one arm of the chair.

She spent most of her time watching me play with Ruby's clit, pussy, and tits, because I spent a hell of a lot more time doing that than delivering any spanks.

Both of them repeatedly begged me for mercy. Not to stop the spanking, mind you, but to stop making them so insanely aroused. They repeatedly claimed that their pussies just couldn't take any more stimulation. Of course I wasn't even touching Michelle, but before long she was practically as worked up as Ruby, just from watching and running her hands over herself. (She didn't dare touch her pussy area, because I'd reinstituted the more climaxes equals more spanks rule for her.)

I kept on going. Ruby's body gave up at the eighteenth spank. Just as Michelle had done, she seized up and shook as a great orgasmic wave overtook her. Then it was like her body turned boneless. I practically had to pour her off my legs and onto the bed. However, it wasn't clear who lasted longer, because Ruby was sloppier about saying her line after each spank, and I had to repeat the spank a few times. She also had a much harder time resisting the urge to scream out loud. She was screaming and begging pretty much from the get-go. Plus, I'd spent more time just playing with her body, so her efforts not to cum were probably even more impressive than Michelle's.

After it was all done, I lifted Ruby's naked body and rested it on the bed. She was awake (barely), but her eyes were closed. I could tell she was conscious because she immediately repositioned herself on to her side so her enflamed ass wouldn't touch anything. I sat down on the edge of the bed next to her and tenderly ran my fingers through her short, spiky red hair.

Michelle was in better shape, but she got up, staggered to the bed, and lay down next to her sister. She also laid on her side to protect her ass. "Oh God!" she panted. "Oh God! Master, can I cum now?"

"No. I still owe you four spanks, remember. You can cum once you pay off that debt. And I still owe Ruby three."

"GAAAAAWWWD!" Ruby groaned like I'd just told her she'd failed all her classes and would have to repeat the last year of high school. Her voice warbled up and down uncontrollably, almost like she was ululating.

Actually, I'd just made up the three number, since I'd never made clear how many she was going to get in the first place. But it sounded about right, given what Michelle had gone through.

Michelle, as the far more coherent one of the two at the moment, asked, "What do we have to do to wipe the slate clean? And please! No more spanking! That was really HOT, but my ass can't take any more!"

"Yeah!" Ruby agreed, despite being half-dead. "Anything but that!"

Michelle sat up, showing surprising vigor. "I know! I'll suck your cock! Right now! I know I'm not supposed to during this ban, but I kinda wanna do it anyway. Kinda really badly! You really showed us our place! You need a big reward!" She nudged Ruby's shoulder. "Actually, Ruby, we both should do it together. Don't you think Daddy deserves a long, slurpy, super-suction double blow?"

"Uhngh!" was all Ruby could say to that as she lay there, sweating and panting. Her eyes were still closed.

I said, "That's a nice offer, but how can it be part of your punishment if you're both so eager to do it?"

They both groaned with disappointment.

I was still stroking Ruby's hair, but it was turning more into a head rub. She was getting so relaxed from that, it was like she was melting into the bed. "Besides, what about your sex boycott? I wouldn't want you to violate that. I said no penis touching, and I'm sticking to that."

They groaned again.

I continued, "Besides, I have a better idea. I'll wash the slate clean, and I won't even spank you again until tomorrow if you both wear what I want, when I want, and act as sexy as you can when I want."

They groaned with frustration yet again. Michelle's question explained why. "You're gonna spank us AGAIN?! Tomorrow already?"

"Yep. You're my sex toys and cock slaves, so get used to it. I'm gonna spank you every single day, if I can have my way. But that can mean a lot of things. It could just be a few friendly slaps while you're in the middle of blowing me. Or it can mean a seriously bad bad spanking that'll keep you from sitting on chairs for days. I say it's up to my whim, and there's some truth to that, but mostly it's up to you and how you behave."

They contemplated that for a while. Ruby even opened her eyes to communicate non-verbally with Michelle.

I kept on massaging Ruby's head. I would have done Michelle's too, but she was lying further away from me, out of easy reach.

Finally, Michelle said, "Fair enough. But I feel obliged to say that your deal is kind of a rip off for you. You're our Master, so we have to obey your every command. We'd be dressing sexy for you anyway."

"True, normally. But what did you wear today? Normal clothes. And why? You claim a special exception because of the sex boycott. I'm saying no special exceptions. I will tolerate your avoidance of my penis for now, but in all other respects, including what you wear and your body mannerisms and so forth, I expect you both to behave like typical, good, and properly devoted cock slaves. For instance, no humming the Darth Vader theme whenever you see me. That's the price for your defeat here, and then I'll wipe the slate clean. Is that clear?"

"Okay," Michelle said with a heavy sigh.

But Ruby said to her, "Michelle! It's only three spanks! Well, three for me, four for you. Should we give up so much for so little?"

Michelle said, "He could make those last spanks as hard as he wants. He could even use the paddle! Is your ass ready for that?"

"No way!"

"Besides, he beat us fair and square. You and I were thoroughly defeated. This is how a powerful master treats his slaves! He UTTERLY defeats us, mentally and physically, with his smarts, strength" - her eyelids fluttered closed as she worshipfully sighed - "and huge horse cock!"

"That's true," Ruby uttered. She was still extremely relaxed, but her eyes remained open and her body was reviving.

Michelle asked, "But Daddy! Master... Tomorrow... tomorrow, you won't spank us like that, will you? I don't think we could take it. I know my pussy couldn't take it. I never came so hard or so often in such a short time. The whole thing was one deliriously joyous roller coaster ride, which is great, but to do it every day, that would be like eating a GALLON of Ben and Jerry's Chunky Monkey. Too much of a good thing!"

"Don't worry," I replied. "It probably won't be like that tomorrow." I stressed the word 'probably.' "It depends on how you behave. Most especially, it depends on how willful and demanding you are."

Ruby protested, "But we're staging a rebellion! We kinda have to be willful and demanding. That's the whole point!"

"True," I conceded. "But maybe it's good if you lay low for a day or two, and let your asses recover. Don't try anything tricky."

Ruby and Michelle both shot worried and disappointed glances at each other, as soon as I said "tricky."

That confirmed my suspicions that they'd had something devious planned. But now it looked like they were going to have to rethink that and at least delay their scheming a day or two. They didn't know it, but that was the main purpose of my erotic yet harsh spanking. I figured they had something in the works, and I needed more time for Sue Ellen or Mindy to uncover their plans.

I added, "And remember, Nicky's coming home soon. It'll look awfully suspicious if you two find it tough to sit."

Michelle grumbled, "We'll be okay in a couple of hours. It really wasn't THAT bad. Frankly, I think we need to recover more from the non-stop orgasm-a-thon than from the spanks. The way you kept ordering us not to cum meant that when we finally did, it was like... nuclear! Like some kind of Three Mile Island burn a hole to the center of the Earth total orgasmic meltdown!"

Ruby nodded as best she could, given her body was still limp as a wet noodle.

I got up and tenderly kissed them both on their noses. I whispered "I love you" to both of them, which resulted in happy and contented purrs.

I took a cold shower.

When I got back to my bedroom, both girls were sleeping on my bed where I'd left them. I dressed in some casual clothes.

I crawled between them and shook them awake (with my hands on their big tits instead of their shoulders). "Sorry, girls. You can't sleep here. Besides, your spankings aren't over."

That opened their eyes wide in a hurry. Really wide! Their bodies jerked from a dreamy half-sleep state to full consciousness. With my hands gently kneading tit-flesh on both sides of me, I could actually feel their hearts start to wildly pound.

I explained, "Don't worry. I'm not going to abuse your asses any more. Well, not right now, at least." I grinned at that. "But you crawled here, and the spanking isn't done until you do that in reverse, meaning you have to crawl back to your room the way you came in. Assume position number two, ask to be excused, and then you can crawl back to your room and sleep as long as you like."

A minute later, the two of them were standing before me with their hands above their heads. But they looked like the undead, and it was obviously a struggle for them to keep standing like that. Even bedraggled, sweaty, and wasted, they both looked utterly ravishing.

In unison, they asked, "Master, can your humble cock slaves please be excused?"

I was kind of blown away. How did they manage to say the same thing at the same time? Had they practiced that somehow? But I didn't ask. Instead, I said, "You're obviously wiped out, so I'll be brief. Traditions are important. Our spanking tradition is starting to become clear. So I'll expect you to do the same tomorrow."

They both moaned incredulously at that, even though I'd told them this already.

Ruby muttered quietly to Michelle, "Death by orgasm!"

Michelle nodded. Her eyes were large with a mixture of desire and worry.

I said, "I heard that. But remember, today was exceptional. Expect something different, and probably less intense, tomorrow. Some things will remain the same, like the crawling, but others will change, like how much I feel like playing with your ripe and busty bodies. Perhaps I'm doing more of that because of the sex boycott. Or maybe less. Who knows how it'll be tomorrow? We'll find out when it happens. You're dismissed."

They pretty much collapsed to the floor so they could get on all fours. Then they more or less dragged themselves rather than crawled out of my room.

I waited until they'd closed Michelle's door, and then I snuck down the hall and put my ear to the door. I figured they were both so wiped out, they wouldn't give any thought about being overheard. That is, if they didn't just fall asleep immediately. But I was lucky, because they started to talk without lowering their voices.

Michelle groaned, "Oh. My. GOD! That was so intense!"

Ruby groaned too. "You're telling me! We're dead! We're dead!"

"What do you mean?"

"Can you imagine doing that EVERY DAY?! I wasn't joking about death by orgasm!"

Michelle replied, "I know, but what a way to go! Can you just imagine? If being spanked by Daddy is that good, how will it feel when he finally FUCKS us?!"

Ruby gasped. "Oh my God! FUCK! Fuckedy-fuck-fuck-fuck! Jesus H. Christ on a pogo stick! That is fucking UNREALl! I can't even imagine! All I know is, we have the best Master ever."

"You said it! Phew! Isn't he just so, well, masterful? ... The way he, well, just... everything! I felt like I was just totally played and defeated, but in a good way, you know?"

Apparently Ruby nodded, because after a pause, Michelle continued, "And the crawling! The crawling! Was that fucking AWESOME or what?! I totally want to crawl naked everywhere now."

Ruby said, "Me too! I was so humiliated and horny that I didn't think I could make it down the hallway! I must have left a gallon of pussy juice on the carpet!"

"Same here. In all seriousness, we're going to have to go back and clean up all our leakage later. Especially where Daddy spanked us. There must be a fuckin' LAKE there by now!"

"Yeah. Good cock slaves always clean up their cummy messes. That's what you and Mindy have always told me. I'll bet he never even thinks about who cleans up after messes like that, but someone's gotta do it."

Michelle replied, "Why should he? He's the Master. It's not his problem. His job is just to sit there and get pleasured and serviced. But what I'm wondering is how we'll be able to make our boycott work, when he can so masterfully manipulate us like that. I was so ready to do ANYTHING for him! I would have begged and begged to suck his cock, except I was too horny to speak!"

"Well, actually, you kinda did," Ruby pointed out.

"Yeah, I know. But that was after. I'm talking about during the spanking. And when he crammed his fingers in my mouth-"

"Shut up!" Ruby complained. "Don't make me even more cock hungry than I already am. I'm totally drooling already. He did that bunch of fingers thing to my mouth too, you know. It was so fuckin' HOT!"

"It was! So how are we going to make this boycott work when he says no tricky stuff? Should we hold off on our-"

Ruby interrupted again, this time with a loud moan. "Awwww, come on! Michelle, please. Not now. My eyes are sewed shut, and I'm about to fall asleep any second. We've gotta come up with some new strategies. I dunno, be more proactive maybe. Something that is NOT guaranteed to get our asses seriously wailed on in the next 24 hours!"

"But it's such a foolproof plan! If we're successful-"

Ruby griped, "Later! Worry about that AFTER we nap."

"Okay," Michelle said drowsily. "But I'm worried. He's just too... irresistible! Did you notice he didn't even cum once? And he forced us to cum over and over and over!"

"He's the man! How can we resist him?"

Michelle sighed longingly. "I dunno. All I wanna do is just... serve him!"

"Same here" - Ruby yawned - "but we've gotta be strong. We're never gonna succeed with our boycott unless we can be strong. And that means resting and recovering. Just think about the horror of having to kiss those stinky boys, and be strong!"

Michelle simply uttered approvingly, "Sister!"

I waited, expecting to hear more, but both of them apparently took Ruby's encouraging comments to heart and fell asleep straight away.

I wasn't proud about listening, but they'd tricked me so many times in seducing me that I didn't feel too bad about it. For instance, it was hard to have much sympathy for their privacy when they'd had a secret peep hole into my bedroom for years. Besides, this sex boycott was serious business, and I needed a leg up. It would have been a much more serious matter to put listening devices in their room - I wasn't going to go that far. But they weren't even making an effort to keep their voices down, and if I could hear them from the hall, I figured that was their loss.

Unfortunately though, I didn't hear much that was of use. Yes, there was vague talk about new strategies, and I gathered that they were probably going to put on hold some tricky scheme that had been about to go into motion. That was good, but it left me in the dark as to what their new plans would be. I figured they didn't know yet either.

The whole spanking experience had been pretty tiring for me as well, so I went back to my bed and took a nap.
