Boundaries

They lay in silence for a few minutes. The only sound was their heavy breathing. It was as if both of them had just run an exhausting race.

The only thought going through Alan's mind was wondering how long it would take for his dick to recover, so he could give his mother the proper fucking she so richly needed. Looking at her massive boobs heave up and down with every heavy breath, he figured it wouldn't be long before he was hard again and he would be inside her.

Although she'd had some intense orgasms of her own, she wasn't feeling much of a post-orgasmic letdown. Everything was still too exciting to believe. She thought, Okay. Wow! I've gotta just chill out and stay calm. But how can I?! That's like living my entire life and only now discovering what color is. Or FOOD! This is practically as big as discovering how good it is to eat food! But perhaps that's not far off, because this kind of feels like the first REAL sex I've ever enjoyed. I know I've done things with Ron, letting him fuck me from time to time. But all of that pales in comparison to THIS! So it's like I've just discovered what sex is about, and it's as big as food. WOW!

The problem is, I'm going to want to do this all the time now. But I can't! I'm still his mother. I'm still a married woman. The Bible doesn't exactly approve of this. Besides, I have to be careful of the slippery slope. We very nearly went way too far! My task has to be helping with his visual stimulation and letting Suzanne stroke and suck him all the time. Every day. Darn. What a lucky girl she is!

She sat up and looked at him. She spoke calmly, if a bit raggedly. "Tiger, I enjoyed that" - that was a gross understatement, they both knew - "but it wasn't exactly what I had expected would happen here. To say the least! Remember. You have to remember, we have to have limits. Just like you have with Suzanne. If I didn't know better, I was afraid for a moment there that you were going to cross a line. We can't have that, can we?"

When he didn't answer, she answered for him. "No! We can't!"

She held his hand and tried to convey the seriousness of her words with a stern expression. Somehow her panties were still on, even though they were completely soaked. Both of them were drenched in sweat. "Do you understand me? Do you have the willpower to maintain limits?"

He suddenly felt very ashamed. His passion was rapidly abating in the wake of the change of mood, and he grappled with hiding his true feelings. He lied blatantly, "Yes, Mom. I would never think of such a thing."

Neither would even state what that thing was, but both knew they were talking about fucking. Mother fucking.

She was still worried. "You weren't planning to..." She couldn't say the words.

"No, Mom, of course not. Really. I don't know what I was doing; I just wanted more. But not that. Never!"

His lies apparently eased her concerns. And it was true that he was suppressing those particular incestuous desires, for the time being. He didn't want to take her forcefully or without her permission, and he was horrified that he'd just come so close to attempting to do that.

"Good." She was happy to hear his response. "If you realize and respect the boundaries, then there's no reason why we can't do this kind of thing more often." A LOT more often! Why should Suzanne have all the fun?! "But you have to remain detached, and remember that this is just a medical procedure."

He nearly laughed out loud at that, until he realized that she was dead serious.

She did mean it, sort of. She still needed some kind of fig-leaf excuse to justify doing something like they had just done, so she clung to the medical-procedure excuse like a life preserver in a raging sea. "Tiger, as long as you have to ejaculate, there's no reason why we can't have some fun in the process, right? I know you and Suzanne have a lot of fun. God, how I know that; she tells me every last detail. But I don't want you to even think about crossing the line. Do I make myself clear? For instance, you shouldn't have tried to grope at my breasts. Suzanne should have taught you that that is off limits. Didn't she teach you that?"

"Yes, she did," he replied, though he recalled that that particular boundary and quite a few others were already sometimes being violated when he was with Suzanne.

But he thought, I still don't understand why I can't touch or kiss, even as I'm getting my cock sucked! Talk about strange rules. But then he remembered, Well, I suppose the whole point is for me to ejaculate. Cocksucking helps that a lot more than kissing or tit-fondling would, so it makes sense in a weird kind of way. Plus it feels really, really, really good! He chuckled silently.

"Good," Susan said, fondly rubbing the top of his hand with her own. "That's a good dear." She was surprisingly firm about not wanting him to touch her breasts simply because she was so very sensitive there. She worried she'd lose all control if she let him fondle her tits extensively, and she'd wind up getting thoroughly fucked before she knew what was happening. Despite her rapidly evolving beliefs about sex, she still considered that a grave sin, on top of which, it would be incest.

She said, "Now let's get things cleaned up here. I'm sorry I got carried away and got you too excited. I will - we will - do better next time. And look: it seems your mommy has made a mess on the carpet. A very big mess!"

Suzanne had been calling her "Mommy" sometimes during their more excited conversations, so she had started using that term in her own thoughts. It had been years since she'd referred to herself like that to Alan, but some part of her was still feeling very naughty and she'd discovered that saying it turned her on.

The two of them started cleaning the mixed fluids that had dripped and splattered everywhere. (In fact, the fluids were almost all from Susan's leaky pussy.) Their raging urges gradually came under control, even though Alan still only wore a T-shirt and Susan just her soaked panties.

Even then, Susan was still riding an erotic high, although it wasn't the off-the-charts all-out lust she'd felt when she'd been bobbing on and licking him. She deliberately delayed putting on any more clothes, reveling in the freedom of staying nearly naked (due to her soaked panties) in front of her studly son. She felt a never-ending "pinch me; I'm dreaming" joy. She had yet to be wracked by serious guilt or regret.

Susan grabbed herself at the crotch when Alan wasn't looking and swished her panties around. Her sticky juices made lewd squishing sounds, but she found the sound delightful. She'd never been so wet in her life. She touched her clit and nearly screamed because it felt so great. Wow! This definitely blows sex with Ron out of the water. I feel kind of bad enjoying this so much, but Suzanne says that sometimes it can't be helped. I've never been so impressed by my brilliant best friend. If she says it's okay, it must be.

Alan dampened the towels in Susan's adjacent bathroom and rubbed the carpet with them while Susan changed the bedspread, since a lot of his earlier loads of cum had gotten onto it. They even found bits of cum that had been splattered many feet away.

He didn't get that much cleaning done, since he was transfixed watching every move his nearly-nude mother made. Although his penis was flaccid for the moment, it was as if he was enjoying a continuing mental orgasm. He simply couldn't get over everything that had happened since he'd come home from school.

After a while, she asked him in a much more subdued and contemplative (but still horny) mood, "Tiger, do you think that what we did was okay? Are you sure that this is ... okay?"

"Yeah, Mom. We just have to maintain those boundaries. After a while we'll become more used to this, and with routine it will be easier to maintain those limits." He fervently hoped that he was wrong, since he was already keen on crossing those boundaries, but he figured that was the best thing to say.

"You're probably right, Tiger." She sighed, now very serious. "I wonder if I'm being a good mom, letting you put your... member... in my mouth... and other things. The way you looked at me just before I sucked you... Tiger, you looked like a real tiger! You scared me! Promise me that you won't ever do that again. I don't know how strong my willpower will be. I'm not as strong as Suzanne. Promise me that you'll be strong for me, and that you will never, ever cross the lines I've set. Do you promise that, with all your heart?"

He thought about it seriously before replying. "Yes. Of course I promise. I would never want to hurt you." He took that kind of promise very seriously. He'd never broken such promises to his mother. But on the other hand, after all that had happened, he wanted nothing more in the world than to fuck her. He wanted it even more than his great desire to fuck Suzanne.

So he mentally searched for a loophole. "But like yesterday, you had me put suntan lotion on you, even though I'm not supposed to touch you. What if something like that happens?"

"Of course, Tiger, in a situation like that, that's different. If I say it's okay, then it's okay. But don't do anything otherwise, okay? Not even in your thoughts, if you can help it."

"Okay." He'd found his loophole, and it was a big one. She's not saying that I can't go further or even fuck her, but that she has to give permission first. That's only fair. I'm not a bad person; I'm not a rapist. I swear to myself I'll never violate that rule and do something against her will.

They finished cleaning up. The whole time they had been cleaning, Susan had still worn nothing but her panties and Alan just his T-shirt.

The more Alan recovered from his last orgasm, the more he grew distracted by her luscious body, especially her continually jiggling boobs.

She seemed to take her sweet time cleaning up, purposely shaking her rack as she rubbed the carpet with a damp towel. Now that she'd gotten started, all she wanted to do was make her son hard and then suck, lick, and stroke him until he was empty, over and over again.

She enjoyed the constant sight of his penis, and the fact that he wasn't wearing shorts. But she was extremely frustrated that he was still flaccid. She was tempted to up her sexy teasing to get him stiff once again.

As they finished up, she pulled her panties down a bit and said, "Look, they're still wet!"

He drew close, ostensibly to check out the wetness of her panties, although many other aspects of her naked body caught his interest. Once he stopped looking at her exposed bush and pussy lips, he noticed that, sure enough, there was a large puddle of cum collected in her absolutely soaked panties, and more of the fabric was thoroughly wet.

He inhaled deeply, savoring the aroma of her musky snatch; it was a smell he was growing to love. He saw from mere inches away that her slit was still leaking copiously. He watched a rivulet of her pussy juices drip down her thigh.

She bemoaned her soiled panties as she pulled them the rest of the way off. "Oh dear. So sorry for making this mess, Son. It was very improper of me. I guess I'll have to go put these in the wash."

She tossed them away and stood there in her naked glory. She didn't even attempt to cover her pussy with her hand. Yes! Mmmm! This feels GOOD! Taking my panties off might not seem to make a big difference, but it does. This is totally naughty and yet total ecstasy. Freedom! This is how I should be all the time: completely naked for my son! I don't know why, but it just feels so good and so right, like I BELONG like this forever! The only thing better would be to be naked AND have his great fat stiffy in my mouth. Oh dear. Susan, get a hold of yourself!

She looked at his crotch yet again, and licked her lips with delight. He was trying to hide the fact that his penis had re-erected. Since he still wore only a T-shirt, he had to keep a hand on his lower abdomen to keep his newly raging hard-on hidden under his shirt, pushed up towards his stomach. However, there was no way for him to conceal it, not under those conditions.

She added huskily and knowingly as she pointed at his crotch, "That is, unless you need some more help down there."

He realized with a start that her cleaning in the nude and the display of her panties had been a calculated ploy to get him hard and ready again. But he was tired, so tired that he was afraid of a complete collapse. "Thanks, Mom. I'd love that, but I gotta take a nap first. We should do that first thing when I wake up."

She hugged him and tenderly kissed the top of his head. As she'd recently grown so fond of doing, she delighted in rubbing her hard nipples in circles around his chest.

He again felt the desire to throw caution to the wind and kiss and grope her wildly. But due to his tiredness he could only take so much excitement.

She said as their bodies stayed pressed together, "Thank you for your willpower, my big strong son. Mommy loves her Tiger so very much." She kissed the top of his head once again, and held him some more, but this time her hug was just tender, rather than an overwhelmingly erotic assault.

He smiled widely. "You know I love you too."

Her face practically glowed with delight upon hearing that. "I do. And what's so great is that we have a new way of expressing our love for each other." She reached down to his crotch and took his boner in her hand. "Just look at you, Son. Look at this! You're a real man now. There's no doubt about it! Such a BIG man!"

He groaned lustily, because she'd started jacking him off again. He thought, Oh, man! What a dilemma. That feels so dang good. But my body is crashing. If I don't leave to take a nap, I'm gonna fall asleep on my feet. But my dick IS erect, and I can tell she totally wants to suck me again. How can I turn that down?! But I have no choice.

He said, "Mom, sometimes after a guy has an orgasm, his body pretty much shuts down for a while. Even though my dick is stiff, as you can see and feel, I've just gotta take a nap right now or I'm gonna collapse. You understand, don't you?"

She pouted, "Oh, poo!" She was still sliding her fingers up and down his thickness.

"We can pick up right where we left off when I wake in a little while, okay?"

She let out a heavy sigh and nodded reluctantly.

He hurried back to his room, where he immediately fell into a deep, deep sleep.
