Under My Thumb: Part 3

Chapter 6

He waited a couple of minutes, until he sensed she was feeling better. Then he said, "Mom, I have bad news. I'm kind of upset at you."

She frowned with dismay. "Why?! Don't I do all I can to help you out and keep you happy?!" She was still rubbing his sweet spot, but she brought her other hand over and cupped his balls to show what she meant.

"You do, you definitely do. You've been so great that I can't even put into words how much I love it, and how much I love you. Except for one thing. This rule of yours, where I'm not allowed to touch your tits. That changes every five minutes, it seems. It drives me crazy."

She let go of his erection, so she could place his hands back on her ample tits. She held his hands there and solemnly spoke. "Forget that rule! My nipples, my tits - they're yours. Yours to own. Don't even let me joke about denying them to you anymore, because it's not my place to deny them to you ever again! It'll mean that I'll be that much more perpetually horny and crazy for cock if you get me excited playing with my tits, but so be it. Please, you'll have to spank me if I ever push your hands away. Promise me you'll spank me good and then have your way with me - minus that one thing."

"I promise," he said as he chuckled some more. Man! She's making it so easy to bring up spanking! It's like she's practically begging me to do it. Aunt Suzy is right: it's something she needs from me, to confirm our new roles. I'm feeling a lot better about this.

She brought her hands back to his crotch and resumed fondling him, but with more vigor than before. "I'm sorry to deny you my pussy - I mean, my cunt - but take my offering of my tits instead. All I ask is that you go easy on me with sucking on my nipples, and try not to do that unless I'm ready for it. I truly worry that I'll lose all control, and you'll end up fucking me. Besides, I can't take too many orgasms like the one you just gave me!"

He laughed. "Okay Mom. I'll only pinch them now and then." He pinched both of her nipples at once.

She cried, "No! Don't! Too sensitive!" But she thrust her chest closer to him in delight. For once, even Alan could realize that a 'no' was a 'yes.'

He was having a lot of fun with her, but he knew he couldn't get distracted now. So he **** himself to frown, and then say, "I'm glad you're changing that rule. But, that said, I think it's only right that I punish you now for blowing hot and cold on letting me play with your tits for so long. You say you're my 'big-titted sex toy mommy, ' and yet you often wouldn't even let me touch your tits! Including when we came into this room earlier!"

She dropped her head submissively. "I'm sorry. You're so right!"

He **** himself to act offended some more. "Furthermore, you promised me a blowjob right after dinner, but then you got a call from your cousin and got cold feet. I thought you were proud to be one of my personal cocksuckers?"

"I am, Son! I am, so much! I've never been so happy. But you're right. I let you down, twice in one day. I think I need to be spanked. Hard!"

He nodded gravely. "I think that would be best." Man! So easy! I couldn't ask for a better set-up. "There's no time like the present. I want you to lay across my lap. Right now."

She looked at him with amazement. "What, now now?"

"Yes. Now. I'm waiting. Don't give me a reason to spank you even more."

Her head reeled and she truly felt dizzy as the implication of what was happening sank in. She sat up in bed, feeling fully energized and alarmed. She loved the idea of getting spanked by her handsome son, but she also had serious concerns about it. She blurted out, "But ... I'm your mother! I know I just said I deserve a spanking, but is it really right for a son to spank his own mother? What will happen to my authority over you?!"

He said, "Normally, no, it isn't right. But our situation is far from normal. I'm eighteen, which makes me legally an adult. Our relationship is shifting. I'm still your son, but I'm also the 'man of the house, ' as you keep telling me. I'll continue to defer to your motherly wisdom most of the time, but I'm the one in charge now, for most things. If you're serious about being my 'personal cocksucker' and my 'sex pet' and so on, then you need to walk the walk and not just talk the talk."

She gulped, and nodded. Her heart was racing from the thrill of him taking charge like this. The implications of what he was saying were almost too exciting for her to comprehend.

Feeling emboldened, he said, "As the man of the house, I have the right to spank you, or anyone else in the house, any time I feel like it. And that starts now, here, with you!" He pointed to his lap, indicating she should lie across it.

She looked to where he pointed, and saw his stiff erection poking up. She reached out and resumed stroking it. "Can I ... can I just suck on it for a while? Your words ... they made me ... so hot! I'm hungry for cock! Your cock!" Her chest swelled with pride as she exclaimed, "My SON! The man of the house!"

But he said, "Not now. There will be plenty of time for that later. I want you to lay down on my lap, just like a naughty little girl." He realized he could be more comfortable if he scooted back so his back was against the headboard, so he did just that. Then he propped up some pillows behind him to get even more comfortable. "Okay. I'm ready."

Susan was in awe as she got into position. This is ... the most exciting thing ever! I know he swatted my ass a few times yesterday, but that was just kind of playing around. This ... this ... it feels official! This isn't just a spanking; he's taking control! He's TAMING me! Even more than before! I'm falling further into submission to my own son, and nothing has ever felt so good!

Both of them were very aware of the symbolic importance of her position, lying naked across his lap. He reached out and brushed her long hair off her back as best he could, so he could run his hands up and down her fair skin. He proceeded to do just that. He loved caressing her smooth and shapely back, and he enjoyed her firm thighs as well, but it wasn't surprising that he focused most of his attention on her ass.

As he did that, she reached underneath her body with one hand and found his erection. Her hand was trembling with excitement as she resumed stroking him. Oh God! He's gonna spank me, for real! I wonder if it's going to hurt? Actually, of course it's going to hurt, but how much?! I'm so glad that I at least have the reassurance of holding and stroking his great big cock! It's only right that a well-hung son spanks his big-titted mommy! Regularly!

Alan had to pause and rest for a minute, because things already were nearly too exciting for him. Okay. Time to take a big breath. He did so, and then did it again. That's better. Aaaah. Jesus H. Christ! This is crazy! I really need to chill out before I even start and not let this go to my head. All this talk about me being "the man of the house," I need to remember that it's mostly just talk. It's true that I'm taking charge when it comes to sex, but otherwise, in reality Mom is still the one who runs the house. She's still the one who I look up to for advice and guidance. Well, Mom and Aunt Suzy almost equally, to be honest. But that's still true for both of them.

We're entering a time where we're going to pretend otherwise. Mom gets off in a big way on the idea that I'm completely in charge, and there's no harm in letting her feel that way. But the important thing is that I have to stay grounded and remember that isn't really true. Except for sexual stuff. And, admittedly, that's a pretty big exception! Phew! That's a damn exciting exception, too!

Susan still had a hand underneath her body that was stroking his hard-on. He had to clench his PC muscle some, but he decided he could handle that level of stimulation for now. Then, with his fingers exploring Susan's pristine ass crack, he recalled Suzanne's advice that he could use the spanking situation to wear down Susan's rule against him touching her pussy.

So he said, "Okay, Mom, before we get started on the spanking, I'm going to have to check you for wetness."

Susan was alarmed. "What do you mean?!" She figured he was referring to her pussy, and she unthinkingly clenched her legs together.

Looking at her thighs locked together, he said, "Yep, that's what I mean, your pussy. Remember, this is a punishment. So you're not supposed to get any enjoyment out of it." (Actually, he knew that was not true, and the whole point was to give her pleasure. But he understood that the pretense had to be maintained.) "As a result, I need to check that you're dry before we start, and that you stay dry until the end. Open your thighs."

She whimpered shyly, "But I'm not dry! Far from it! How can I be, with you being so manly, handsome, and sexy, and putting me in my proper place like this?! Just feeling my body across your lap is keeping me constantly gushing. Plus, I've got your hot, stiff cock in my hand, and you know how horny that makes me. And things are bound to get wetter still down there, because the spanking hasn't even started yet!"

He used both hands and pried her thighs apart. She didn't try to fight it. "Well then, maybe you should let go of my dick. You'll need to do that when I start the spanking anyway. Try to stay dry, and whatever you do, don't cum! If you do, I'm gonna have to give you a punishment that'll make this upcoming spanking seem like small potatoes!"

She bit her lip and grimaced. She was already close to cumming as it was, and thoughts of a more severe punishment only excited her more. But she was determined to try her best. She even let go of his cock, in the hope that would help keep her calm.

But then Alan reached between her legs and ran a finger through her swampy pussy.

She squealed in alarm and squeezed her ass cheeks and thighs tight, trapping his hand. "What was that?! You know you're not allowed to touch me there! That still stands! I'm sorry, but I MUST keep that rule! I know I just changed the other rule, but if I let you touch me there, there's no telling what'll happen! You could end up really fucking me! Heck, I could even end up begging you to do it!"

His head swooned as he imagined that happening. With such thoughts on his mind, and her body to fondle, he didn't need for her to be actively jacking him off to be extremely aroused, as he was right now. He **** himself to calm down some, and then said, "I know, Mom, I know. And I'm not asking you to change that rule. But we need a partial exception for spankings. I have to check you there and clean you off. We really need a dry pussy for this to work."

Of course that was bullshit, and she probably knew that on some level. But it was a fig-leaf excuse that allowed her to let him break that rule without her having to feel bad about being weak.

He made a show of looking around the room. (He was so horny that it didn't occur to him that she couldn't see his face while lying face down over his lap.) "It's a shame I don't have some tissues or a towel or something. I guess I'll have to use my hand."

She clenched her ass cheeks in alarm again. "Don't you still have something like that near your bed, to help you masturbate with?"

He grinned. "Sorry, Mom. Not anymore, since I have you, Amy, Sis, and Aunt Suzy. Plus, I'm not about to commit the 'sin of Onan.'" He had trouble saying that with a straight face, since he found the whole Onan story ridiculous, but luckily she still couldn't see his face anyway. "Anyway, I can just use my hand, like this." He started wiping her pussy clean with the tips of his fingers. "Remember, stay calm. Think of unarousing things. And whatever you do, don't cum! Then we can get started on the spanking."

Susan whimpered helplessly. That's easy for you to say! You're not the big-titted mommy about to get spanked for the first time by her huge-cocked son! I can't even handle the THOUGHT of getting spanked. It's too exciting! Once it starts, I'm gonna cum in the first minute, for sure, if I even last that long! And then I'll need to be punished for that, and that'll probably be something even MORE arousing, making me cum without permission even more, and on and on, in an endless cycle! I'll end up totally and utterly TAMED! And even that thought is too arousing for me to handle! UGH! Dear Lord, please! Help me!

That passing thought about the Lord helped her a great deal. She was a genuine religious believer, and prayer was a big part of her life. So she closed her eyes and recited some well-known prayers in her mind. That diverted much of her attention.

And she was very grateful for that, because in fact, Alan's attempt to "clean" her pussy was merely a pretense for him to play with it and all around it. He refrained from sticking any fingers directly in her slit, since that didn't fit with the cleaning notion. But he made up for that by repeatedly running his fingers over her wet lips and brushing past her clitoris. Sometimes, he would "accidentally" push a finger in her soaking gash a little bit, but not too far or for too long.

He wasn't doing much with his other hand, so he brought that around her front and under her huge boobs and began fondling them.

Susan's prayers were helping her calm down some, but that went right out the window once he started fondling her super-sensitive breasts. She squirmed with lust and worry. "Ti-Ti-Tiger! What do you think you're doing?!"

He said with a smirk, "I just need to hold you there to keep you in place. Kind of as a counterbalance."

She thought, He IS keeping me in my place, in more ways than one! So HOT! But it's too hot! I can't take it! She panted, "But then, why, why ... why are you fondling my nipples so much?!"

He pretended to be clueless. "Oh, am I? Oops. I guess that's how it goes. Remember, you changed the rules. I can fondle your tits as much as I like, anytime I want."

Just hearing that practically made her want to swoon, or scream in erotic ecstasy. OH NO! He can! He can! That's so like him. I change the rules and immediately he takes full advantage! There's no stopping him! And now he really DOES own my tits! I was just saying that earlier as something to arouse us, but now it's TRUE! Oh God! Lord, please, give me strength to endure his sexy, groping hands! I don't know which is worse, the way he's rolling my nipples between his fingers or how he keeps sliding his thumb back and forth over my cunt!

So far, he had restrained himself from probing inside her pussy, aside from the occasional minor "accident." He didn't have a valid reason to do so, as that didn't fit with the "cleaning" theme, and he rightfully worried about pushing her too far too fast. But she was so hot to trot, squirming and heaving in his lap, that he figured he could get away with it. So, pretending more cluelessness, he said, "I don't understand. You keep getting wetter and wetter, no matter what I do. Where's it all coming from? Maybe I should go straight to the source and try to plug the leak there."

With that, he plunged two fingers deep into her hot hole.

She was so surprised and aroused by that move that her entire body actually rose up and fell back down on him. She would have cum for sure, but she struggled with all her might not to, due to his prohibition against it. "AAAAAIIIIEEEE! NO! Tiger, no! Please, no! Too hot! So hot! Can't ... can't take it! AAAAAH!"

He pumped his two fingers in and out several times, making her squirm and moan even more. Of course he wasn't actually trying to "plug a leak," but that provided another fig-leaf excuse.

She thought, And to think I didn't know which is worse! The cunt is way, way worse! This is why I don't let him touch me there! I'm gonna cum so, so, so HARD! And then ... then ... I'll probably beg to get fucked! I've never been so horny in my LIFE! He has total control and I'm helpless to stop him, because it feels so damn GOOD! I really AM just his big-titted plaything!

She clenched her teeth and shut her eyes tight. Her hips squirmed around as she struggled with all her might to delay her climax.

He realized how close she was, but he didn't want her to cum just yet. His plan was to keep her riding right at the brink of orgasm for as long as possible, in the same way she frequently did to him. So he pulled his fingers out of her and let her recover somewhat, until her frantic panting abated.

As he took a brief rest, he thought, This is awesome! I love how my "cleaning" just makes her wetter and wetter! I particularly love to see her this horny and happy. Man, life is good!

He'd mostly forgotten his qualms about spanking her; he was beginning to be anxious to get the spanking started. So he said, "Unfortunately, I'm not having much success here in getting you dry. I guess we'll have to leave your pussy like this, for now, and get the spanking started." He couldn't resist stroking his fingers back and forth over her sopping-wet pussy lips a few more times. "But, whatever you do, don't cum! Is that clear?"

"Yes, Son." Her pulse raced a bit faster and her body tingled all over as she sensed the spanking was about to begin. Too bad Brenda can't be here to see this! She seems to have a real special thing about getting spanked! At least I'll get to tell her about it later. She'll understand what a huge deal this is! It's mommy-taming in action!

Alan too, had to brace himself as he contemplated what was about to happen.

She broke the silence by asking, "How ... how many times are you going to spank me?"

He thought, How many times should I spank her, I wonder? Twenty? Thirty? I'm so clueless. I have NO idea how much is too much! Maybe it's better not to announce a number first and just do as much as feels right. Yeah, that sounds good.

He said, "I have a number in mind, but I'm going to play it by ear. We'll see how well you do, and how much you can take. Remember that no matter what happens, I love you. It might hurt some; in fact I'm sure it will. But I'm not going to go too far. Most of all, remember that I'm doing this for your own good."

She replied meekly, "Yes, my love."

He thought, I can't believe I just got away with the "I'm doing this for your own good" line. How ironic. She used to tell me that all the time when I was a little kid. Man! The shoe is definitely on the other foot tonight! Wild!

Then it occurred to him they needed a kind of ritual. So he spoke off the top of his head as he continued to fondle her tits. "Okay, Mom. I'm going to swat your ass in a minute. When I'm done, I want you to say, 'Number one, ' or whatever the number is. Then I want you to say ... um..." He recalled from erotic stories that there was a tradition to maintain here, and it was good for her to repeat some kind of statement after each swat. But he was so very turned on that he couldn't come up with a good, appropriate statement right off the bat.

Luckily for him, Susan had been contemplating being spanked by her son a lot lately, especially in her daydreams. So she drew from previous fantasies when she suggested, "What if I say, 'Number one.' And then, 'Thank you, Son, for punishing your naughty mommy."

He grinned from ear to ear. "Very good! Let's do that. Okay, here we go. Brace yourself!"

Chapter 7

Susan closed her eyes, clenched her teeth, and clenched her ass cheeks.

Alan raised his hand up high and then brought it down onto her ass.

There was a loud "whap". But, in fact, he didn't really hit her that hard. He still had a hard time doing anything that seemed like hurting his mother, so he eased up at the last second, and without really intending to.

But Susan reacted just as if he'd swatted her as hard as he could. For her, the actual physical act was a smaller factor than the mental aspect. The fact that her son was giving her a real spanking was such a thrill that she was nearly delirious with lust. As soon as she felt the impact, she cried out, "Number one! Thank you, Son, for punishing your naughty mommy!"

She followed that with some husky, erotic moaning. Already, she was struggling hard not to cum. She knew exactly where her son's erection was, and that was too tempting to resist. She reached under her body, found his hot pole, and sighed blissfully as she resumed jacking him off.

Right as she did that, he went back to fingering on and around her pussy. He said, "Good job, Mom. But hang on a second. I've gotta check your pussy again before we continue."

That made her moan and "mmmm" even more. She reflexively clenched her ass cheeks again.

But he said, "Sorry, Mom. You can't clench like that. I can't check you properly if you do. In fact, no clenching at all during the spanking, and that's an order. If you do, I'm going to have to add more swats before I'm done."

She whimpered, "But I can't help myself! It's a natural reaction!"

"Well, try. Or we might not be done here for a very long time."

She tried hard, and mostly succeeded. But she felt the need to do something, and since she couldn't clench, she found herself squirming and writhing in place a great deal instead.

He didn't try to stop that since he didn't see any harm in it, and he found her movements very sexy.

She went back to praying in an attempt to distract herself from her son's pussy checking. But instead of standard, memorized prayers, she made up her own. Dear Lord, please, PLEASE! Please, help my pussy not gush so freely, so Tiger can finish his check fast! I feel like cumming so very much, and I can't cum at all! I must obey my studly boy. Please! Please! Help me not cum without permission! I don't want to be punished even more! It's unseemly! He's my son, but he's the man of the house now too, and he has total control over me! I'm just his big-titted mommy plaything, and I can't tell him no! Lord, please! Everything is so sexy! Too sexy! Too hot! Make it less hot, somehow! I'm begging you!

Her prayers continued in that vein. In fact, they were less prayers and more just her erotic stream of consciousness thoughts, with the occasional appeal for God's help thrown in. They didn't help her calm down much, if at all.

Then Alan announced, "Okay, here comes swat number two!"

Susan clenched her ass cheeks unthinkingly. She still held his cock in her hand, but she stopped stroking it as her entire body braced for impact.

He waited. "Nope. What did I say about ass clenching?"

"UGH! I can't help it! I'm too horny!"

"Try."

She tried. She managed not to clench, but her ass was wiggling and writhing so much that it was a moving target.

Her fingers were sliding wildly all over his boner, obviously with very little conscious control on her part. It occurred to him that when he swatted her again, she was likely to squeeze his shaft painfully hard, just as she tended to clench up elsewhere. So he said, "Hang on. Mom, you gotta let go of my dick. I just remembered that part of the spanking tradition is that you need to pin your hands behind your back, just like they're handcuffed there."

"Oh." She was disappointed to let go of his erection, but the idea of having her hands behind her back like that was thrilling in its own way too. She loved feeling totally helpless and in his power. So she brought her hands behind her back as requested.

He announced, "Okay, get ready..."

A few seconds later, he raised his hand up high and swung it down. He slapped her other ass cheek this time.

Susan grunted. Then she cried out, "Number TWO! Thank you, Son, for punishing your naughty mommy!"

A strange voice said, "Brother, you call that a spank? Weak!"

it was only a strange voice for a few startling seconds, because both Alan and Susan quickly recognized the voice as Katherine's. Alan had the benefit of being able to easily look towards his door and see her standing there, smiling and waving at him. She was wearing a blouse that she'd just put on in her room, but she'd left it completely open in front, exposing most of her ample charms.

Susan couldn't see towards the door without twisting her body uncomfortably, but she considered that a small blessing, because she didn't want to look. She shut her eyes tight, and her cheeks turned red. "Angel?! What are you doing here?! Please! Don't look!" She let go of her son's erection and tried to cover her ass cheeks with both hands, as if that would help preserved her modesty at all.

Katherine said, "Mom, how could I NOT look? My room is right across the hall, you know. When I hear all kinds of spanking and shouting sounds, how can I not check to see what's happening?"

However, Katherine's statement was intentionally misleading. She'd actually been downstairs doing naughty things with Suzanne, which she didn't want to admit to her mother. At least it was true that she'd heard the sounds, since Susan's screams had carried that far.

Susan clenched her ass cheeks even more, as her entire body tensed up. "Okay, I can understand that. But now you know, so you can go. It's just a spanking, thank you very much!"

Katherine responded, "Just a spanking? I beg to differ! How often does one get to see a son spank his own mother?! Not very often, that's for sure. Although, I imagine that from now on we'll be seeing it a lot. Isn't that right, Bro?"

Alan certainly didn't mind the intrusion. He knew that Katherine's presence would humiliate Susan further, which in turn would arouse her even more. Besides, it was fun to talk to someone else, especially a gorgeous, naked sister. "Sure thing, Sis. From now on, any time Mom is bad, she's going to wind up with a cherry red ass and probably a mouth full of cum. Although, Sis, I should warn you that the same thing applies to you."

Susan nearly passed out because she found those words so arousing. She particularly loved the phrase that she was "going to wind up with a cherry-red ass and a mouth full of cum." (She immediately forgot about the "probably.") Her ass humped up and down in a **** effort to delay her impending orgasm.

Katherine replied, "I know, Bro, I know. And I certainly don't have a problem with it, because that's your right! We're your obedient fuck toys, after all. We're all about dropping to our knees to suck and serve, and if we fail to please, then we get spanked! Hard! Isn't that right, Mom?"

Susan merely grunted in the affirmative. "UNH!" She thought, Shut up, Angel! Please! If you say anything more, I'm going to cum! I'm so close! I'm dying! UGH! But I can't! I can't!

In fact, Katherine had been watching the spanking from the very beginning without being noticed. She'd even taken a few photographs, figuring it was a moment they would all want recorded for posterity. So she knew exactly what was going on. But she pretended to be clueless when she nodded at the way Alan was diddling with Susan's clit, so she asked, "Why are you touching Mom in her naughty spot like that? Isn't that forbidden?"

Susan gasped out, "It IS! Please, Angel! Get him to stop! I'm ... I can't ... Gonna cum!" After an initial coherent outburst, she was unable to express herself because she was that horny. She wanted to say that she needed Katherine to enforce the rules since she found herself helpless to do so. But instead she ended up moaning and "mmmm"-ing quite loudly.

Alan managed to continue to diddle with her clit, as well as her slit, despite her constant writhing and gyrating. He looked up at his sister and said serenely, "Normally, that WOULD be forbidden, but there's a special spanking exception. You see, I need to check to make sure she's not too wet. Obviously, she's supposed to be punished, not aroused."

Katherine smirked knowingly as she said, "Obviously." She understood full well that this was an erotic spanking, and the punishment was only a thin pretense.

He brought a hand back to her breasts, which he'd been neglecting for a while. "And sometimes I have to hold her here or she might slip off my lap."

Katherine had a hard time not laughing at that. "That seems reasonable."

He pretended to be upset. "The problem is, I must be doing something wrong, because she's getting wetter and wetter." He pulled his hand from her crotch and held it up. "Here. Come look. See how wet my fingers are?"

Katherine eagerly pounced on the invitation to come closer. She walked right up to the edge of the bed and glanced at his hand. "Hmmm. Indeed." She was tickled pink, and couldn't stop smiling.

Susan brought her legs together and tried to cover her pussy and ass crack with her hands as best she could. "Don't look! Please! Don't look!"

Needless to say, Katherine was looking. "Mom's been a bad mommy, hasn't she?"

"She has," Alan replied.

Susan wailed, "Oh, God! This is totally humiliating!" She thought, This is like my every dream come true, but my nightmares are coming true too! Even though I'm losing their respect and authority, it's SO HOT! I'm so horny that I fear I'm going to literally lose my mind! Tiger is playing endlessly with my HOT CUNT! And Angel is standing right there watching!

Alan felt he had a good sense for just how much humiliation would make Susan hotter than an inferno, and how much was too much and would make her miserable. He sensed that Katherine's presence and comments was taking Susan to that tipping point. The spanking was mind-blowing enough to begin with, and he sensed his mother was extremely close to cumming, which she wouldn't want to do with her daughter there too.

So, knowing that Susan couldn't see his face, he nodded at Katherine and then nodded at the door. Mostly with his facial expressions, he was able to convey that he was worried about pushing Susan too hard.

Katherine was disappointed, but she got the message.

Once he saw that his sister understood, he spoke out loud, for Susan's sake. "Sis, sorry, but you should probably go. This is kind of a private thing between me and Mom."

Susan sighed heavily with relief. THANK YOU, LORD! Miracles can come true! Now, if I can just somehow not cum! Or at least hold out until Angel leaves the room! I'm not going to last much longer in any case!

Katherine nodded. Then, realizing Susan couldn't see that, she said, "Okay. No problem. But it's good that I saw this much, because, Mom, remember that I still owe you a spanking too, from what you did this afternoon. Remember? I'm definitely learning from what I see here. But we'll have to wait until tomorrow for that. Okay, see you guys later!" She walked to the door.

Susan's eyes had been shut tight, but they opened and bugged out wide when she heard Katherine say that she was going to get another spanking tomorrow. That was very nearly the last straw. OH NO! BOTH my children are going to spank me from now on?! Lord, have mercy! Pleeeeassse!

Alan had been "checking" her pussy all the while, with a particular emphasis on checking her clitoris. She felt she was hanging onto the very edge of a cliff, like a character in a Bugs Bunny styled cartoon, and her last hand-hold was slowly and inexorably slipping away.

She waited a few **** seconds until she heard Katherine close the door. Then she shouted out, "Son, please! Permission to cum!"

Alan realized that he'd badly misjudged her arousal level. His plan had been to keep her near the cusp of orgasm for the entire spanking, and then he'd give her permission to cum at the end. But he'd gotten too excited and "checked" her pussy far too much. After just two swats, she had clearly gone beyond the point of no return, so he had mercy and said as he gave her nipple a hard pinch, "Permission granted!"

Susan let out a long, incoherent wail as her resistance collapsed and she came hard. In fact, she screamed like a furious berserker Viking warrior, her orgasmic cries echoing through the entire house. Her ass bounced up and down off the bed, and her legs and arms thrashed around uncontrollably.

Alan had to withdraw his hands from her slit and her boobs, due to how she was moving so much. Since she was still improbably wearing her high heels, he had to be particularly careful about her flailing legs. He used his hands to try to keep her from falling off his lap.

But, after about a minute, her multiple orgasm started to peter out, and her wiggling and writhing subsided too. Unexpectedly, he plunged two fingers into her burning hot slit.

Her eyes opened and bugged out, exactly like before. Her jaw dropped in near comic fashion too, because that took her by complete surprise. Another epic orgasm hit her, like a punch to the gut. She screamed and screamed, and tears poured down her cheeks. They weren't tears of joy or sorrow, but instead were a sign of her total emotional and physical overload.

When her orgasm ended after another minute or so, he decided to have mercy on her and just let her be for a while. She didn't quite pass out, but she was so out of it that she was effectively a dead weight on him. It took a minute or two before he managed to extricate his legs from under her. He got off the bed, stood up, and looked back down at her resting form. I've never seen anything so beautiful. Mom is totally orgasmed out!

The spanking ended in a strange way for him. Not only did he not cum himself, he didn't even come close. In fact, his penis quickly went flaccid once he was off the bed. In fact, he hadn't felt much direct stimulation at all, at least by his recent standards. Susan did jack him off some of the time, but she was so distracted that it was a far cry from her usual talented motions. But he didn't mind. This spanking was for his mother. And even though there was precious little actual spanking in it, he knew it had served its symbolic purpose. Plus, it had left her about as sexually satiated as she could possibly be.

As he stared at her gorgeous nude body, he thought, Good! I'm glad I didn't cum, or even get close. It's about damn time for some payback. Mom helps me out so much, every single day. She deserves more huge orgasms like that. And what's nice is that I didn't have a problem spanking her. The truth is, I adore seeing her cum like that! God, it's a thing of beauty! I made her like that. ME! Phew!

He left the room and quietly closed the door behind him. He decided to take a shower to revitalize himself. Then he figured he'd stop by Katherine's room to chat with her, and maybe check to see if Suzanne was still downstairs after that. He wasn't looking for any sexual help. Although he hadn't climaxed himself, he did earlier thanks to Susan's prolonged blowjob, and he felt sexually satiated from the spanking too.

He turned the light out as he left his room. He figured that if Susan wasn't asleep already she would be soon, and she would want to nap for a little while.

But he was wrong about that. Susan's body was absolutely wiped out, but her mind was still racing with excitement from being truly spanked by her son for the first time. She did rest for about five minutes, but she was thinking intently all the while. Then she turned on the lamp next to Alan's bed, and picked up the phone extension on his bed stand.

She dialed Brenda's number. She couldn't wait to share what happened with her new good friend. "Hello, Brenda? It's me, Susan!"

Brenda's pulse started to race. She'd learned over the last few days that virtually any phone call with Susan ended up making her extremely aroused. But she tried to keep her cool. "Oh, hi. What's up?"

"Guess what? You won't believe it! Tiger just SPANKED me! And I'm not talking about a little playful slapping of my ass cheek during a blowjob, like he did yesterday. I'm talking about an honest-to-God, official, naked mommy across the lap, proper spanking!"

Brenda's effort to keep cool was shattered. She practically fainted, because that was about the hottest thing she'd ever heard. She screamed incredulously, "NO!"

"Yes!"

"NO!"

Susan chuckled, because this was the kind of reaction she'd been hoping for. "I'm telling you, yes! I'm calling you while lying buck naked in my son's bed. He's gone, probably to play with his sister or auntie, while I'm lying here completely and utterly DESTROYED from some of the biggest orgasms humanly possible! He really put me in my place!"

Brenda's eyes bugged out wider and wider. She was rendered speechless, and her heart pounded so hard it was downright dangerous. Getting spanked was her great secret fetish, due to her peculiar history of getting spanked frequently by her mother as she was growing up. She'd already heard from Susan that Alan had spanked Katherine a couple of days ago. The fact that he spanked Susan meant that he'd surely spank all of his women. Brenda realized that meant that as long as she continued to grow closer to him, he'd be spanking her soon as well.

She shouted even more emphatically. "NOOOO!" She fell into the nearest chair, because her legs gave way under her. She was huffing and puffing like a freight train with uncontrollable arousal.

Susan chuckled some more. "Yes, I'm telling you. Yes! Let me tell you all about it!"

Brenda thought, Oh God, dear God, NO! Susan you can't do that, or you'll kill me from an overdose of pure lust! Holy shit! The implications of this are staggering! If I had ANY doubt I want to be one of Alan's personal cocksuckers - and I don't! - this puts that issue to rest, for good! Alan, you've won me!

She exhaled several times, trying just to breathe. "Okay, Susan. Tell me! Tell me everything!"

Susan bubbled with excitement as she began her story from the moment she'd entered her son's room. Her post-orgasmic exhaustion was fading fast as she delighted in sharing her experience with Brenda.
