Chapter 666 Things Spiralling Forward.

Susan was so happy that she was practically walking on air. She also was about as hot and horny as she could possibly get, and the fact that she'd just had a particularly big climax after a whole series of smaller ones didn't cool her ardor one bit. Images of getting royally fucked by her son dominated her thoughts.

When Susan walked out of the inner office and into the waiting room where her two children sat, her eyes went straight to her son. She gave him a "come hither and fuck me" look that nearly knocked him out of his chair.

"Son! Come here!" she barked with atypical urgency.

Alan stood up, not quite sure what was going on. He was completely floored that his mother was wearing nothing but her high heels and her glasses in such a location. He was further flabbergasted when he saw Xania standing in the doorway behind Susan, staring at him with a triumphant smirk.

Susan crossed the room and kissed her son on the lips for a long time. Almost immediately, one of her hands went to his crotch and she started stroking his dick to full hardness through his blue jeans.

But she didn't like the impediment of his jeans, so she quickly managed to unbutton them, reach a hand inside his fly, and directly stroke his newly stiff erection. A part of her was aware that Xania was standing there watching, but she didn't care much, since she was just that aroused.

As their necking went on, Alan glanced at Katherine. He worried this might bother her in some way, but she just flashed a big smile and gave him the thumbs-up sign.

When the French kiss ended, Susan cooed in his ear while lovingly jacking him off, "Son, this talk with Xania has been the best thing for me ever! Everything is so much CLEARER to me now. I don't have to feel guilty or ashamed about servicing your cock, and yes, even serving it! Serving it!"

She looked down at her sliding fingers. Mindful that Xania was watching, at first she'd tried to at least maintain some decorum by stroking his hard-on inside his jeans, but now it was poking out through the fly. She pondered trying to cover it up, but she was proud of her son's cock and she liked the idea of Xania seeing just how big and impressive it was.

With her heart racing and her embarrassment soaring, she pulled his jeans down enough to completely expose his shaft plus his balls too. She got busy stroking his boner with one hand and fondling his balls with her other hand.

She licked his jawline to his ear as she purred, "Son, I want to serve your cock! Forever! I'm not just saying that as something to arouse; I well and truly mean it. THIS is what I was born to do!"

The "THIS" she referred to was the way her fingers were rubbing his sweet spot. "It's not just my duty, it's my calling and my destiny!"

Normally, Alan would have had his hands fondling Susan's bare ass cheeks by now, and/or maybe he would have been playing with the fulsome globes pressing into his shirt. He wouldn't have been deterred by the fact that Katherine was undoubtedly watching everything. But he could see out of the corner of his eye that Xania was still standing in the doorway and obviously watching too, and that left him uncertain. He kept his hands in the air while he tried to figure out what the hell was going on.

Xania coughed loudly. She was pleased at what she was seeing, but she felt obliged to break it up before it got too hot and heavy. She had her own hot and heavy fun planned.

Seeing that she had everyone's attention, Xania said, "Susan, as the saying goes, you go, girl! Good for you, showing your feelings like that!"

Before she could say more to get Susan to stop her fevered stroking, Alan asked incredulously, "Xania, are you really okay with this?! I mean, really?!"

Xania folded her arms under her massive rack. "Alan, don't you remember what we talked about before?"

He said, "Well... yeah! But it's one thing to, you know, talk about it in the abstract. It's another thing to actually see it, and in your own waiting room, no less!" His heart was pounding wildly as he looked down at Susan's fingers pumping up and down his shaft, and pleasuring his balls too. But he seemed helpless to stop her because it was all too arousing to be believed.

Xania looked at him a bit peevishly, like she was annoyed at his lack of comprehension. She pretended to be completely unfazed by the two-handed handjob she was witnessing. "Why would I say something I didn't mean?"

"Um..." He was having a hard time thinking.

Then coming up with a response became kind of a moot point, because Susan had been licking and kissing her way all over his face, but then her lips wound up touching his and she couldn't resist giving him another passionate French kiss.

Katherine fully approved of anything that furthered her mother's sexual liberation, but she was feeling increasingly left out. She stood up and asked, "Hey, Mom, can I help out?"

There was a long pause, since Susan was consumed with her kiss. But she finally broke away long enough to say, "I have this urge to say no, but maybe... maybe that's not such a bad idea. What do you think, Xania?" The sound of Susan's hands sliding through sticky cum and the smell of that cum filled the air.

Xania replied, "I think that's an excellent idea! From what I understand, Alan's penis sometimes requires great amounts of stimulation, and even then it can take practically FOREVER before he cums!"

Alan's arousal level surged even higher as he recalled the fact that Xania knew that through first-hand experience earlier in the day. The way she emphasized the word "forever" made him remember just how long she's stroked and sucked him before they even got down to fucking.

"That is soooo true!" Susan exclaimed.

Xania continued, "It's up to you all, of course, but I think having two sets of hands, or even two mouths, working on his thick erection at once... I don't see a problem with that. It might even be the best way to go about things on a regular basis."

Katherine was all in favor of lots of joint blowjobs, so she helpfully suggested, "It's kind of like, if you have a really heavy box, it's better to use two people to lift it."

"Exactly," Xania replied.

"MMMM!" Susan moaned into her son's mouth. But she broke the kissing again to say, "Did you hear that, Tiger? Who knows? Before long, Angel and I might be sucking you off together, every single day!"

Katherine was still miffed to be left out of the action. But hearing that cheered her up. "YES!" She pumped a fist in the air. "That's what I'm talking about!" She raised her hands, intending to undress and get started on a double blowjob right away.

However, Xania held both hands out. "Whoa! Hold on there! It's a good idea, but not right here, right now. My time is limited. Susan, I'm going to need you to sit and wait on your own for a while because I'd like to speak to Katherine and Alan at the same time. Is that okay?"

Susan wore a blissed-out smile on her face, while she kept on stroking her son's boner. She'd brought her other hand up from his balls so she could double-pump him. "That's okay. Everything is very, very okay. I'll manage." She muttered under her breath, "Dear God! So much cock!"

Xania coughed even more obviously.

However, Susan either didn't hear or she pretended not to hear. She kept on with her relentless fondling while she looked into her son's eyes and said, "Tiger, you know what Xania told me a little while ago? 'How can anything that feels this right be wrong?' Those were her exact words! And it's so true! Sliding my bare tits over your chest, feeling my hard nipples press in... Humping my ass up and down... Squeezing your cute ass... Which I haven't actually done yet, because I can't let go of your cock!"

Somehow, she upped her enthusiasm even more. "Because that's the BEST! Just HOLDING your stiff meat in my hands makes me shiver and tingle all over! But then, when I get to stroke it, it's like an endless orgasm for me! Son, I love it so much!" As her passion rose, her fingers pumped up and down faster and faster.

Alan's face was straining and his heart was still racing fast. He was fighting hard not to cum too quickly, especially since he wanted to impress Xania with his staying power.

Susan was building up to another climax of her own. "So thick! So long! So perfect! So RIGHT! And when I drop to my knees and take you in my mouth-"

Xania had been so fascinated watching Susan's heartfelt declaration that she forgot to put a stop to the action. But when she heard Susan start to talk about blowjobs, she could tell what was coming next, and she knew she had to act fast. She practically shouted, "Susan! Please!"

Susan was in such an ecstatic sex fog that it took her some long moments to respond. And then, all she could say was, "Um... Yes?"

"You should probably let go of that. NOW!"

"Oh. Sorry." Susan very reluctantly let go. Xania's "NOW!" sounded serious, and Susan's submissive side needed to obey.

But even then, she didn't completely stop. Although her hands withdrew, she went back to kissing her son's face as she said, "Son, don't worry! Everything is going to be all right. If nothing else, you'll always have your big-titted mommy to serve you. Always! I'd been so very worried about today, but everything is going to be just fine!"

While she was talking and planting small kisses here and there, she rubbed her naked body against his clothed one. And since she was no longer jacking him off, she tried to make up for that by grinding directly against his boner. She had it trapped up against his belly and she was stimulating it in this manner almost as well as if she was using both hands.

Alan had to say, "Um, Mom, good! But... please! Go, now! Or I'm gonna make a big mess!" Then he remembered, "Wait, actually, I have to go." He took a step back, causing them to disengage.

Looking down, he saw his hard-on pulsing and twitching so much that it was almost comical. He had to count to ten and take some deep breaths before he could even begin to calm down. He was still on a hair trigger. But finally he managed to tuck his boner back into his jeans and zip up.

He looked up at Xania and saw her smirking at him. Clearly, she was having a ball.

Katherine walked up to him and held her hand out. "Need a hand, Big Bro? That thing looks dangerous!"

Her eyes motioned towards the obvious bulge in his jeans. "It's like a throbbing wild beast. Let me stick my hand down your front so I can pet it and keep it warm."

He looked at his sister and rolled his eyes. "Thanks, but no thanks. As it is, it's a close thing I don't make a big mess." He took his hand in hers. "Here, I'm going to hold your hand just to make sure it behaves."

Katherine giggled. "Well, okay, but who knows what kind of mischief the other one will get into!" She giggled even more.

Once the two siblings walked into the inner office hand in hand, Xania went back out to the waiting room to briefly talk to Susan.

Xania stood there as a trembling and excited Susan settled down into a chair. She realized she needed to figure out a way for Susan to expend her sexual energy. Plus, she didn't want her to be alert as to what was happening inside her inner office. "Susan, I'm going to need you to stay relaxed for another session later."

"Okay. I guess I'll just..." She looked around and saw the same magazines she'd been perusing earlier. "I'll read, I suppose." Then a thought hit her, and she clutched in embarrassment at her bare chest. She also crossed her legs to hide her pussy. "But I'll need my clothes! Oh dear!" She started to get up.

Xania motioned for her to stay in her seat. "Remember what you were saying earlier, how being topless helps you relax? That goes doubly for being topless and bottomless too, doesn't it? I can assure you no one else is going to come here to this waiting room today."

Susan looked around furtively. Her mood was rapidly changing, and cooling down, now that Alan was out of the room. "Are you sure? Anyone could come in. I think I'd feel better wearing at least something."

Xania looked at the naked mother, and thought, If this woman ever wanted to make it in Hollywood, she could go so damn far. I've always been held back by my naturally sinful and slutty looks. At least that's what they say. And they say my breasts are so big that they're intimidating and I'm only good for porn films or wanna-be porn films. But Susan has such a naturally wholesome look, and at the same time she's so sexy! She would have the town eating out of her hand, even with her boobs being as big as mine.

Inspired, Xania decided to push her luck a bit. She took away a "Good Housekeeping" magazine that Susan had glanced at, and said to the buxom mother, "You must be bored with those old magazines. Remember what I said earlier about how you should envision your Alan fantasy as much as possible? Now's a good time."

Susan looked up in surprise. "Again?!"

"Yes, again."

"But... I just did that."

"I know, but repetition is important. You have years of conditioning that incest is bad to overcome. The way to do that is with frequent visualization exercises. I want you stay naked, completely naked, and do exactly what you did before: masturbate to thoughts of getting fucked by your son!"

Susan's eyes widened as she reflexively clutched at her exposed rack. "But... but, once I start, I won't be able to control myself! Especially after everything we said and did already."

"Do it! Losing control is good. Why do you need to control your urges at all? Here: imagine that he's coming home from school. You're ready to greet him with a nice welcome home cocksuck. And sure, you can do that for starters. But his cock is so POWERFUL, and THICK, and DEMANDING! It needs more! Much more! It needs to plunge deep into your hot cunt!"

Susan's mouth hung open in shock and her bare chest started heaving wildly as she vividly imagined that scenario. "My goodness! Xania, do you realize what your words are doing to me?! I can practically feel him sliding in and out of me as it is." She whispered shamefully, "My pussy is hot!"

She looked around the room for some kind of excuse or escape. Thinking about how she could feel her pussy lubricating, she pointed out, "I'll make a big mess all over your nice chair. And my children will see it when they return. It'll be so embarrassing!"

"Don't worry. We have plastic seating. And I'll cover for you. They won't know. Besides, so what if they do? You were just jacking your son off as you kissed him. The time for modesty is over. You are a fuck toy for your son! Doesn't that make you feel good?"

Susan admitted, "You don't even begin to know how good."

"So, stop holding back. Fully embrace your role!"

Susan still seemed doubtful. She looked around as if expecting to find a secret camera watching her. "But... I'm in the waiting room. It's not just my children who could see me. Anyone could walk in!"

Xania spoke with supreme confidence. "The door is locked, and nobody else is coming here today in any case."

"Even so, I don't know..." Susan was mindful of how carried away she got with her last visualization, and she was afraid of that happening again in what she still felt like was a more public location.

Xania tried a different tack. "Aren't you a sex cow? Sex cows have to make a lot of pussy juice, all day long, don't they? That way, Alan can drink up your pussy juice when he isn't filling his mouth with all the milk gushing from your nipples. Isn't that right, my little sex cow?"

That definitely made an impression on the sex-addled mother. Her eyes brightened in a flash. "Oh yes! You're right. It's my duty to cum hard all over this chair for my cattle prod. Uh, I meant, for my son, and his, uh, prod. Gosh! You're so UNDERSTANDING! You even understand my sex cow fetish. I could just kiss you!"

Xania quipped, "Please do."

Susan was so excited with these sex cow ideas that she immediately laid back on the couch, closed her eyes, and began fingering her pussy, even while Xania still stood there.

Xania was a bit disappointed that she didn't get another kiss, but she let it slide since she was eager to return to her inner office for further fun with Katherine and Alan. She admonished, "Don't forget: visualization exercises. You and Alan fucking. Think of him as a big strong bull mounting his favorite cow. Remember, he's just come home from school and his balls are about ready to burst, they're so full of sperm. Think about that long, hard cock you've just been stroking. Think about stuffing it in your mouth and wrapping your lips around it."

"HNNNGG!" Susan groaned erotically.

"But don't stop there. When you finish giving him a long, sloppy blowjob that lasts until he squirts all over your face, remember that he controls every inch of your body. And he also wants to fuck your CUNT!"

"UNGH!"

"He looks at your cum-covered face and he gets so horny that he just has to have you again! Right away!"

"OH! OH! MMMM!"

"Have fun!" Xania bent over, playfully pinched one of Susan's exposed nipples, and winked at her. The wink went unnoticed though, because Susan's eyes were shut tight and she was already slipping into fantasy land.

Susan plunged two fingers into her pussy.

Xania shook her head, sad once again that she felt she couldn't participate. She opened the door to the inner office, stepped inside, and closed the door behind her.
