Reasonable Bounds

But then I looked across the hot tub at Michelle’s massive bare tits glistening wet in the torch light, and Ruby’s similarly huge, wet, and glistening bare tits on the other side of Nicky. There was no way my penis could go flaccid sitting near the two of them! I seriously doubted one could find two set of breasts that big and perfectly shaped in Hugh Hefner’s mansion!

Then I looked at Nicky. I could see everything above the top of her boobs, but not her boobs themselves. I could see a bit of their upper slopes through the water, but only a bit. Although the bubbles had been turned off for now, the lighting was so poor that the water got pitch black very quickly.

So I told myself, I’m not getting aroused looking at Nicky, I’m getting aroused looking at the gloriously topless Gruesome Twosome! So that’s allowed, right? And my wife is the one jacking me off, and wives can do that kind of thing, so it’s okay. Right? Right!

That was a blatant violation of my “no sexual activity in Nicky’s presence” rule just the same, but I think all the wine muddled my thinking.

I consoled myself that even with the bubbles turned off, nobody could see what was happening to my stiff dick. As I mentioned previously, because the torches were only barley keeping us from being in total darkness, the water got pitch black just a few inches below the surface. I looked down at myself and realized that I could have taken my swimsuit all the way off and nobody would have been able to tell.

Both Mindy and I were so submerged that nearly all of Mindy’s arm was under water. But even if most of her arm had been out of the water that wouldn’t have been a problem, as she was only rubbing my sweet spot with a couple of fingers. So it was a relief not having to really worry about getting caught.

While I was reacting to the start of Mindy’s latest handjob, the girls were still talking.

Michelle waved a hand through the air in a dismissive gesture, setting her twin orbs in motion. “Don’t worry about Daddy listening in. He’s cool. He’s not like other dads.”

“That’s true,” Nicky readily agreed. “But still, everything is weird. The fact that you’re calling him ‘Daddy’ is a case in point. We stopped using that back when we still had some baby teeth!”

Michelle dismissed that with a casual flip of her hair. (I noticed all the women were being very careful to keep their hair dry.) “There’s no law against using that word at any age. Besides, that’s part of the changes since Cindy became his mistress. Now that Ruby is an official sister, I wanted something to remind Daddy of our special relationship. I thought I told you that already.”

“I can see that, I suppose,” Nicky conceded reluctantly. She looked right at me, and asked, “By the way, what’s up with that?”

I asked, “What do you mean? I thought we’d discussed Cindy and me already.”

“We did, but I mean...” Her face started to turn red. “Well, for instance, you’ve got this big bed now, and she sleeps in it, and Mom does too. I did NOT expect that! How does that work?”

Ruby giggled impudently. “Daddy, I think she’s asking about how the sex works!”

Nicky turned her head away and blushed even more. “I am not!”

I chuckled. “Don’t worry, Muffin. I can tell that you are curious about that, but you’re too shy to talk about sexual matters.”

She didn’t say anything, which confirmed my guess.

I said, “I don’t mind talking about it. Think of it as a ‘the birds and the bees and the bees’ talk.”

She giggled nervously at that joking extra “the bees” mention, while still looking anywhere but at me.

I continued, “A little bit of partial nudity or frank talk is okay, because we’re all so close. Right?” I added that first part to hopefully help put the little snit about the Gruesome Twosome being topless behind us.

Nicky nodded shyly.

“I won’t get graphic, since that would obviously be getting a little TOO comfortable with each other. But suffice to say that later tonight I’ll probably make love to Cindy. Or maybe your mom. Or perhaps both of them. It depends what they’re in the mood for.”

Nicky’s curiosity got the best of her, and she couldn’t help but ask, “So wait. They’re in bed with you when you’re ... you know, all at the same time?!”

Michelle teased her, “I think we know what the word for that is, Sister, and it isn’t ‘you know.’”

Nicky growled, “Shut up,” and poked Michelle’s nearest shoulder. That wasn’t the kind of thing you’d expect the sweet and gentle Nicky to say. However, because Michelle could be so aggressive in getting what she wanted, Nicky had learned that sometimes she had to push back hard.

Michelle, though, didn’t take that kind of thing lying down. She turned her exposed upper body towards Nicky and poked her right back. “No, you shut up!”

Nicky turned to Michelle too and repeatedly poked back, like someone impatiently hitting an elevator button. “No, YOU shut up!”

I knew from experience that these sister-against-sister arguments were likely to get even more childish, probably leading to an all-out poke war. And while I admit that would have been a lot of fun to see, I had to do the fatherly thing here. So I said loudly, “LADIES! SETTLE DOWN!”

That got their full attention, and Ruby’s too. I was delighted to notice though that when Nicky sat back against the side of the hot tub to face me, she was sitting considerably higher than before. The water line was just below her nipples now. Despite her red bikini top, that was still an extremely inspiring sight to see, and the fact that Mindy was secretly rubbing my sweet spot under the water made it much, much more enjoyable!

I forgot about my vow to not mix sexual arousal and Nicky in any way, shape or form. I blame the alcohol.

Now that I could see Nicky’s nipples above the water line, I was shocked to see that they were erect! There was no doubt about it. I figured it had to have been an involuntary reaction to the fact that we were talking about sexual matters. I resolved to try hard to not say anything prurient, because even though I’d forgotten my vow for the time being, I still had some lingering resolve to do the right thing.

I tried hard to look at Nicky’s face instead of her chest as I said, “I have two lovers, so naturally I have sex with both of them. Yes, while I’m making love to one, the other one is usually present. Sometimes the other will watch, or sometimes join in. But it’s important to mention that they haven’t engaged in any kind of lesbian activity with each other, so please don’t imagine that that’s going on.” I wasn’t being honest on that last point, but I figured Nicky could only handle so much truth at once.

Ruby, pretending to be clueless, asked me, “So how does it work if all three of you are doing it at once?”

“I’d rather not go into that. Let’s not turn this X-rated. Suffice to say that we all enjoy it.”

Michelle was also acting clueless, and yet acting like herself, when she complained, “That’s ALL? That’s all you’re going to tell us?”

“Yes, that’s all. Now, Muffin, I noticed that you cleverly diverted the conversation away from your kind-of break-up with Steve. I too would like to know what the ‘real story’ is there.”

Michelle chimed in, “Yeah! Spill it! He seems like the ideal boyfriend in every way on the surface, so he has to have some kind of secret kinky side or a dark side or something.”

Nicky replied shyly, while unfortunately sinking deeper in the water again, “There’s no big story to tell. Maybe he’s TOO perfect. He’s predictable and...” she floundered, trying to find a safe way of saying what she really felt.

But she finally simply blurted out, “Fine! If you must know, he’s boring. And I’ve decided I don’t really like a guy like that: a young Republican, frat boy, yachting type. I’d like someone quirky and surprising, who’s into alternative music and culture. Steve’s all about money. He’s always going on about how much he paid for his watch or his sunglasses or whatever, as if I’m supposed to swoon over that.”

She looked right at me. “Dad, those aren’t the values you raised me with. You taught us that money isn’t an end, it’s just a means to an end. But Steve, I think he’d make love to a pile of money if he could.”

I chuckled at that image. “That’s too bad. It sounds like Steve isn’t the golden boy we thought he was.”

Michelle added, “Yeah, talk about trouble in paradise. But I’ll bet that’s still not the full story. Sure, you’re not going to marry him if you think of him that way, but he still is a total hunk to look at. I’ll bet that if he was ringing your bell loudly every night, you’d take a lot longer to break up with him.”

Nicky looked into the darkness nervously. “I don’t know what you mean. I don’t have a ‘bell.’” She raised her hands up to make mock air quotes.

Raising and then dropping her arms did wonders to her breasts! They were three-fourths of the way out of water with her arms up, and as her arms came down, her boobs sank down onto the water, setting off a series of small waves.

Meanwhile, Mindy kept on playing with my cock! It had started out subtle and careful, with her just rubbing a couple of fingers on my sweet spot within my swimsuit. But my suit was so tight that there wasn’t much room for her hand in there, so she’d pulled my erection clean out of it. Then, over the past few minutes, she’d grown bolder, or sloppier, or both. Sometimes, she ran her fingers all over my hard-on, although she did seem to prefer making little rubbing motions most of the time.

I still wasn’t worried at all about getting caught though. I furtively looked down towards myself from time to time, and I couldn’t see even a vague hint of the outlines of my body from at least my belly button on down. We were in the dark, after all. The torch lights illuminated our faces and upper torsos, but the light didn’t penetrate far into the water. Since her arm was almost entirely underwater, her arm movements couldn’t give her away either.

My one minor fear was that someone could turn on the bright overhead electric lights, or the hot tub lights, and maybe Mindy’s naughty game would be exposed in an instant. But who would do that, and for what reason? Even then the depth of the water would still probably cover everything. And I’d have a chance to react if I saw anyone getting even near the light switch.

I guess I’d gotten spoiled from being jacked off and sucked off so much. I barely even thought about what Mindy was doing to me, and just relaxed and took part in the conversation. This was more of the “new normal” of being a harem master, apparently.

The propriety of letting her do that less than five feet from where Nicky sat didn’t register much in my brain, I’m sad to say. I gave no thought to what might happen if Nicky found out somehow, for instance, maybe because I didn’t think that was possible. I suppose I could have lamely talked my way out of it if she did find out - maybe I could have argued that Mindy was “sleep stroking” just like sleepwalking - but it wouldn’t have been good, to say the least!

Michelle answered Nicky’s comment about not having a bell. “You don’t know what I mean by having your bell rung? I’m trying be indirect here, since you’re such a ‘delicate flower’ type.” Her voice dripped with sarcasm as she made the “delicate flower” comment. “It’s what men and women do together in bed at night.”

“Oh.” Nicky’s face was getting redder.

Ruby spoke up. “Let’s cut to the chase. Have you or have you not had sex with Steve yet?”

Nicky sat back and up, as if trying to escape the hot tub, but the only practical effect was that it lifted her huge, wet tits all the way out of the water and set them bouncing. “I can’t answer that! Not with Dad here!”

Ruby was taking charge of this. She told me, “Close your eyes.”

I did.

Mindy clearly was listening, because I could sense she was growing excited by the way her fingers were sliding faster and faster over my shaft.

Ruby then said to Nicky, “Okay, instead of having to say anything, if you’ve had sex with Steve, blink once. If you haven’t, blink twice.”

I was keeping my eyes closed, so I couldn’t see her answer, but it didn’t matter much since Michelle immediately said in a triumphant voice, “A-ha! I knew it!”

And if that wasn’t clear enough, Ruby followed up with the question, “Just occasionally, or lots of times?”

Ruby’s response of “Wow” left little doubt there. Plus, she asked another question, “Has he been your only one? Or were there others before him?”

Nicky asked, “Wait. One blink means what, in this case?”

“Oh, sorry. One blink means only him, two means there were others.”

I didn’t have to guess the answer with that one either, because Ruby asked, “Were there a LOT of others?”

Nicky griped, “Ruuuuuuubyyyy! Come on. You know me! I’m not some kind of slut!”

Michelle said, “Of course you’re not. I don’t think you have anything to feel embarrassed about. You’re just like every other girl your age, testing the waters, finding out what sex is all about. That’s cool.”

I was secretly amused at how poorly the blinking secrecy system worked out. The fact that we were all tipsy to outright drunk meant that no one seemed to notice or care too much. I asked, “Can I open my eyes now?”

Nicky sighed. “You might as well. You pretty much figured out all my answers anyway, didn’t you?”

I opened my eyes. I was stunned all over again by the sight of three dripping wet teenage racks in front of me, none of them smaller than an E-cup, and only one bikini top between them. Wow!

However, I played it cool, and replied, “I did, but it’s no big deal. I’d assumed you weren’t a virgin already, since you’re a nineteen-year-old college student and you’d been dating the same guy for a year. And given how beautiful and desirable you are, if you were still a virgin, I’d be more worried about that.”

Nicky asked me shyly, “Do you mean that? Do you really think I’m ‘beautiful and desirable?’”

“Of course! Look at you! In fact, look at all three of you. My God, man!” I briefly allowed myself to openly gawk at their faces and busts, going from one to the other. “It’s a good thing that the water is so hot or I might just get an inappropriate fatherly reaction.”

The girls giggled happily at that. Ruby nudged Nicky’s shoulder with her own, and muttered, “He means an erection.”

Nicky rolled her eyes and muttered back, “Yeah, I figured. Duh.”

Of course, my comment was a lie. Not only did I have a completely exposed boner hiding in the black and murky depths, but my supposedly napping wife was constantly jacking me off! I should have felt like a dirty old man, but I didn’t. I guess that shows just how much I had been sexually corrupted.

As for the heat of the water keeping my penis flaccid, it helped that all our family members were “heat wimps” when it came to the hot tub. We liked it hot, but not painfully so. I wasn’t having any trouble maintaining my erection whatsoever. I probably wouldn’t have had any trouble keeping it up even without Mindy’s secret help, especially when I looked from chest to chest and saw six erect nipples lined up in a row!

Michelle looked Nicky over and playfully poked a finger into Nicky’s nearest breast, touching the edge of her red bikini top. “Girl, you’re way too overdressed. We need to get that off you somehow.”

Nicky didn’t seem alarmed, but just grinned like they were playing a fun game. “Not gonna happen. So there!”

Michelle asked Ruby, “What do you think?”

Ruby smiled playfully. “Oh, definitely. Nicky, it’s RUDE not to join your sisters in total titty freedom. It makes us look bad.”

Michelle piled on the pressure. She appeared to be acting unusually combative with her older sister tonight, for some reason. “Besides, don’t you want Daddy to see just how beautiful and desirable you are?”

To my surprise, Nicky seemed tempted. “Yes, you know I do! But ... I can’t! ... I just can’t!” She closed her eyes and defensively wrapped her arms around her chest. But her arms went just below her massive tits. Instead of covering them up, her arms pushed them up and out, making them appear even MORE titillating!

Just then, Mindy let go of my boner, but only because she wanted to cup my balls. From there, she playfully “tickled” her way back up my shaft. The timing of that made me wonder if she was peeking from time to time and getting inspired by what she saw.

Michelle said, “A-ha! I’ve got an idea. Nicky, I’m going to make a guess about your sex life. If I guess right, then you have to take your top off right now, right in front of Daddy! But if I guess wrong, then I’ll stop bugging you about it tonight. What do you say?”

I was further surprised when Nicky opened her eyes and grinned. “Sure! That’s easy, because I’ll tell you right now that I’m gonna lie. You have no way of knowing the truth, and I’ll just answer whatever I need to answer to win. So there!”

Given that answer, I thought Michelle would call off the bet, but instead she said rather slyly, “If that’s the way you roll, then so be it. Here we go, okay?”

Nicky looked slightly alarmed that Michelle didn’t give up. I think she was starting to suspect that Michelle might have some kind of trick up her sleeve. But she stayed quiet.

Michelle said, “I’m still convinced that Steve is not satisfying you in bed, if you’re dumping him already. Either that, or he really is dumping YOU for being too prudish.”

Nicky chimed in, “I am NOT prudish! And he certainly isn’t dumping me. I’m not really dumping him either. Not exactly. It’s just that our relationship is on hold for the summer.”

Michelle shook her head and made disbelieving noises. “Give it a rest already. Admit that you’re done with him.”

Nicky stared into the water and said in a quiet voice, “Yeah. I guess.”

For some reason, I felt a surge of arousal. Strange. Maybe it was because Mindy was focusing on rubbing my sweet spot again, and that was highly effective. I hoped it wasn’t due to lewd thoughts about what it meant that Nicky was going to be a “free agent” this summer.

Michelle patted Nicky’s back comfortingly. “You see? That’s not so hard. And that’s the right choice. Because it’s like I suspect: not only does he have all the problems you mentioned, but he’s lousy in bed! When you say he’s boring and predictable, I’ll bet you mean that both in and out of bed. I can tell!”

Nicky asked critically, “Is that your big guess that’s supposed to get me to take my top off?”

“No. That’s not all. You see, sex is like pizza: even when it’s mediocre, it’s still pretty good. So that’s not enough. There has to be something MORE! If Steve’s penis is only about four inches long, or less, THEN you have to take your top off!”

Nicky immediately blushed, and her mouth dropped open. “How did you know that?!”

Michelle preened, reveling in her triumph. “Simple logic. Steve is a hunk. He SHOULD be good in bed, even if he’s fumbling around, just because he’s got muscles and youthful energy and all that. Yet you’ve been pretty dismissive of him all day, like he’s lost your respect. And yeah, those other things you mentioned matter, like him being too materialistic, but I could just tell that you’d be acting and talking differently if he was rocking your world every night. But what could it be? It could have been some other things, like premature ejaculation, but I figured usually the best guess is the most obvious one. Some try to say otherwise, but the truth is, size DOES matter!”

Michelle stared significantly and even longingly in the direction of where my erection was, if she could have seen through the dark water. Luckily, Nicky was staring off into space in amazement.

“Damn!” Nicky was impressed at Michelle’s reasoning. But then her eyes opened wide as she remembered the consequences of their bet. “Oh no! I forgot to lie!” She gathered herself, and said firmly, “Good guess, but his penis is actually five inches long, so you’re technically wrong. You lose!”

Michelle rolled her eyes. “Yeah, right. Hand it over.” She imperiously held her hand out for Nicky’s bikini top.

Ruby chimed in, “Nicky, you totally lost the bet. Give it up already.”

A blushing Nicky seemed highly reluctant.

Even though I was dying to see Nicky topless, I had to do the fatherly thing. I said, “Muffin, we’re just playing around. You don’t really have to take your top off.”

Michelle teased her, “Yeah, go hiding behind the protection of Daddy. I knew you’d be a scaredy-cat, but I didn’t know you welshed on your bets too!”

I said to Nicky, “Don’t listen to her. She’s trying to get some kind of rise out of you. Besides, that would be too weird with me here.”

Nicky asked me with curious defiance, “Why would it be weird if I took my top off, but it’s not weird when literally every other woman here tonight did it, even including Michelle?!”

“Um...” I tried to think of a diplomatic way to answer that, but the alcohol and the secret underwater handjob were dulling my brain.

You could have knocked me over with a feather when Nicky glanced at me nervously, dropped her head, and then untied her bikini top and handed it over to Michelle! She smirked in defiance at her younger sister, even while she remained nervous and embarrassed.

However, I didn’t get to enjoy the sight of her bare breasts for more than a couple of seconds, because she immediately sank down until the water line was all the way up to her neck. That wet some of her medium-length brown hair, but she seemed to not be worrying about that now.

Michelle protested, “Hey, that’s not fair! Don’t be shy. Proudly show yourself off, girl!”
