Accidental Penetrations Ch. 03&04

When Dustin woke up the following morning, after having accidentally fucked a second sister in two days, he looked at his sister's bed. She was still there, still sleeping. Before falling asleep last night, he wondered what he would do if she had come to his bed to fuck again. But even though neither of them had any bad feelings about what they had shared, Emily didn't seem eager for a repeat. She hadn't closed the door on the possibility, but Dustin guessed he would have to wait and see. 

Instead of thinking about the beautiful nymph sleeping the bed next to him, Dustin thought about his older sister Erica. The one he had fucked about 9 hours ago. Accidentally as well. Which was, frankly, unbelievable. As the fourth day of their vacation was dawning, Dustin laughed while wondering how many more such surprises would be in store for him. Oh, if he only knew!

Unexpectedly, another memory, this one much older, sprang into his mind. While it was the second time Dustin had fucked one of his sisters, his accidental penetration with Emily wasn't the first time he had fucked a sister. His ex-girlfriend's sister actually. And although that story sounded just about morally as bad as fucking his own sister, it actually began as an accident as well. Dustin knew that thinking about that night wouldn't help his erection, he indulged himself anyway... 

About two years ago, just after he had turned 18, he went to bed in his girlfriend's room. Her parents loved him and had known him for years as Niemira's friend. And so when Niemira and he decided to hook up and become lovers, they were very comfortable about letting him sleepover. They must have known that the two 18 year old lovebirds were having sex, but they trusted him enough to let that happen. 

On that fateful night, Niemira and him made love for a long hour before dropping off to sleep. When Niemira was in the mood for sex, she always made it clear to Dustin. No playing around, no subtle messages. That night was no exception. When Dustin came back from the bathroom he found her completely naked and standing on her bed. Dustin grinned before closing and locking the door. 

The light she used for reading on her bed was right behind her and happened, from his perspective, to be right behind her pussy. In fact, given that it was the only light in the room, it looked like the small space beneath her pussy and between the tops of her thighs was triangle of pure light. "The Bermuda triangle!" he whispered. 

"What?" Niemira asked, looking down at her shaven pussy. 

"The light..." he whispered before kneeling on the bed and planting a wet kiss right on the triangle. Or, more precisely, on the pussy right above it. 

From then on, the Bermuda triangle would become one of their little inside jokes. Niemira was a very eager lover, and had been a virgin when they first became lovers. And so Dustin had the time of his life telling her what he liked and didn't like as well as learning, in turn, what she preferred. That very open and sharing mentality meant that their sex life became amazing in no time. Dustin couldn't find anything to complain about. 

But not having anything to complain about didn't mean that Dustin was blind to other sexy girls. Not even when one of those sexy girls was Niemira's older sister, Hayden. Now, one thing has to be absolutely clear. Dustin loved Niemira very much and thought that she was remarkably beautiful. And sexy. She was about 5'4", thin yet with decent curves, with nice breasts that were hesitating between requiring B cup or C cup bras. Her breasts were high, round and very perky. 

Dustin really liked her aureolas. They were of a decent size, but they were so pale that they nearly faded into the skin around them. There was no clear contrast between regular skin and aureola, except by the end of summer when the sun had turned her skin much darker. 

Niemira also had a stunning ass, as smooth like the rest of her body. In fact, Dustin would come to see that the word "smooth" was perfectly suited. Nice and beautiful breasts that grew organically on her chest, the line of he waist to hip to thigh wasn't particularly pronounced, and her ass had barely visible apple lines. 

Maybe her curves would become more pronounced later in life, but for now, Niemira's body was very smooth. The only flaw with that sweet ass was that she had no intention of ever trying anal... Of course, that wasn't a problem with her ass itself, but every time Dustin stared at it, this little reticence bothered him. 

Even her pussy was smooth. Contrary to many of the models he had seen on the net, her outer lips covered everything. Of course when she was all wet and aroused and while he was playing with it, that little rose blossomed, but otherwise her smaller lips didn't peak out. It was a beautiful pussy nonetheless which, like Dustin's twin sisters, she kept flawlessly shaved. Finally her long mane of black hair crowned her magnificently. 

Then again, as beautiful as a girl could be, she couldn't be everything. Hayden was, on first glance, very similar to her sister. She was exactly the same height and both of them could share most items of clothing. Hayden's body was slightly softer and rounder, but not by much. On the other hand her breasts were significantly bigger. Once Dustin found one of her bras in the dirty clothe's hamper: 34D. 

Dustin knew that Niemira envied her sister's bigger breasts, especially since they hadn't come with a chubby body like many big breasted girls their age. Instead, Hayden was still pretty slim despite the two large mounds of flesh on her chest. Sometimes, while he was having sex with Niemira, Dustin imagined that he was fucking her sister. Although the feeling was profoundly intoxicating, he knew he could never admit to doing it to anybody!

One of the best memory he had with Hayden (a real memory!) was an afternoon they had spent together on their patio. Niemira had been called to work at the last minute and really needed the cash, so she had left in a hurry. The three of them had planned a lazy afternoon under the sun and in the pool and Dustin was frustrated by the sudden change of plans. First because he loved lounging in the sun with Niemira, but second because he also loved watching Hayden in her bikini. 

Oh how that bikini had haunted him! It was a simple black bikini which set off her green eyes and light brown hair perfectly. And while it wasn't overly sexy, a young girl wearing a bikini over her 34D breasts was always a remarkable thing. And her breasts were remarkable! Given that this afternoon would the first such day of the summer, Dustin had been expecting it for a long time. When Niemira kissed him on the lips and disappeared, he sighed and gathered his stuff and prepared to leave. 

But Hayden asked him "Got somewhere you need to be?"

"Er, nope."

"Why don't you stay?" Hayden asked, her pale cleavage glowing in the sunlight. "I know how much you love sunbathing and swimming, so..."

"Well, maybe I could..." Dustin replied, a little surprised. 

He got along well with Hayden, but through the years it had became quite clear that they would never become close friends. In fact, by that point it was just as clear as the fact that he would lust over her for years and years! That afternoon wouldn't mark a turning point in their relationship: they didn't share anything intimate and didn't discover some unexpectedly share interest. In fact, they didn't talk all that much. Music filled the silence. It wasn't an awkward silence, but it was still a silence. 

A silence filled with aesthetic bliss on Dustin's part. That bliss began immediately after he agreed to remain with her, when she asked him to put sunscreen on her back. Instead of saying yes, he had simply grinned dumbly. Hayden had shaken her head with a smile, sighing. "Boys will be boys!" she said. Hayden then lay down on her large towel, on her belly. She reach back and untied her bikini top. "Don't get any funny ideas," she said. But that was all Dustin had! He managed not to do anything stupid but took his time covering her soft back with the cream. "Are you done?" Hayden asked in a playful voice. "I won't tell my sister that you stared at the sides of my breasts the whole time," she added, giggling. 

"Please don't!" he replied nervously. 

"Relax Dustin... As I said, boys will be boys."

The rest of that afternoon was seared into his brain. Almost as much as what happened on that fateful night many months after that afternoon. For hours he watched Hayden as she applied sunscreen to her body and especially her cleavage, as she suntanned, as she dove gracefully in the pool, as she walked slowly out of it, her body dripping and glistening with water... She was, voluntarily or not, consciously or not, giving him an incredible show. By the end of the afternoon, as she was getting ready to head inside, she paused next to him and whispered "Were you glad to have those black sunglasses on?" She then winked at him and walked in. 

That afternoon would turn out to be the high point of their friendship. Nothing else came out of it and there was never an opportunity of a repeat before, almost a year later, things didn't work out between him and Niemira. Nothing happened, of course, except for that fateful night. Nevertheless, people could look back at this afternoon as some sort of precursor for that night, but Dustin knew it wasn't. 

And so, after falling asleep for a while after a great yet exhausting hour of lovemaking, Dustin suddenly woke up and found himself alone in Niemira's bed. It was the middle of the night and everything was pitch black. Dustin shook his head when he realized he had a huge erection and so decided to go look for Niemira, in case she wanted more of it! He silently walked out of her room and tiptoed to the bathroom door. Doing so, he walked in front of her parent's room, which was silent, and Hayden's room, which was equally silent. All the doors were closed, but he knew that Hayden's current boyfriend, Matthew, was in there with her. 

The bathroom's door was closed as well, and there was no light escaping from beneath. "Maybe Niemira went to the downstairs basement," he thought before climbing down the stairs. "Maybe we could fuck there while everybody else is asleep!" But as soon as he turned in the hallway he saw light coming from the kitchen and headed there. He did his best to remain silent, wishing to surprise Niemira. 

Peaking from the hallway, he saw a wonderful sight: Niemira was standing in front of the fridge and the door hid most of her body. Most, but not all. Given that she was bent forward, Dustin could see her lovely ass, her lovely naked ass, sticking out. Backlit by the fridge's light, it made for a very beautiful sight. And an inviting one as well. Deciding to test her ability to contain her surprise and to keep quiet no matter what, Dustin let a big gob of saliva fall on the tip of his still hard cock. He coated it as best he could and then sneaked behind his girlfriend. 

Before she could react he guided his cock against her pussy, was glad to find it wet and then he sheathed his cock completely inside. Niemira gasped when he did, but soon giggled. Dustin loved this position and with the strange backlight from the fridge mixed with the kitchen's darkness, it made Niemira look surreal. Her dark hair flowed all over her back as she grasped the fridge to be able to answer his trusts. Dustin was thrilled beyond words, as he had always loved this kind of surreptitious sex. Her parents could walk down at any second and catch them! Or even her sister! Christ! What would Hayden do if she caught them? Would she leave immediately, would she scream, or, maybe, would she stay and watch?

Dustin knew that she wouldn't do that last possibility. But just thinking about it made him even more excited. He was looking at his girlfriend's ass a he grasped her smooth hips, staring at the junction between her cheeks and his cock. Niemira was moaning very softly, thoroughly enjoying this but fully aware of all the people sleeping around them. Biting his lower lip, Dustin was having the time of his life. Until, fatefully, he saw the small birthmark on his girlfriend's lower back. A birthmark that looked like a small bird. 

The trouble was that Niemira didn't have a birthmark. Her back was flawless. Her sister, on the other hand, did have a bird-shaped birthmark on her lower back. He had stared at it while applying the sunscreen on her back months ago. He was, for heaven's sake, fucking his girlfriend's sister! The shock seemed to throw him out of his body for a moment. He kept fucking her, but in a desultory manner. Christ! He had never been in such trouble before!

Now that he looked at her hair carefully, he noticed that it was, indeed, pale brown and not black like Niemira. The strange backlight effect had made it appear darker. Fuck! Looking down, his eyes widened as he looked at his cock, disappearing now in Hayden's soft pussy. In a moment of lustful clarity, he decided that he was already in so much trouble that stopping now wouldn't change anything. And so Dustin seized her hips in a firmer grasp and fucker her even harder. 

When he did, Hayden whispered "Fucking hell Matthew! You feel so damned big inside me right now! You're making me crazy with that big cock!" She moaned a few times after that while Dustin's head was spinning. "I'm so glad you could get it up a second time tonight! I was afraid I'd have to fuck the cucumber again! Shit this is good! Don't stop!" She moaned again and again before adding "I think you're going to make me cum this time!"

Hayden then unexpectedly pushed herself away from the fridge and turned until her hands were on the countertop. "Take me, take me harder with that huge cock!" With a better angle, Dustin moved his head to the side and saw, for the first time, Hayden's large breasts bouncing around with his every thrusts. Fuck they were gorgeous! Fuck they were big! Dustin could only imagine what they must feel like when wrapped around your cock. Christ!

Hayden was now controlling her moans, which had become dangerously loud. She then lay across the countertop and said "Damn baby... this is so good! Fuck me Matthew, fuck me hard!" And he gladly did! Soon Hayden was just gasping and spasming, her climax seconds away. "Shit! You've never made me cum so quickly! What the hell has gotten into you?" 

Dustin had no idea what would happen when she would realize what was going on, but he did his best to pleasure her. Maybe if she climaxed she would be more forgiving? Well, his theory would be put to the test really soon. Hayden turned her head and rested it sideways on the counter. And that's when she opened her eyes. And saw him. Her mouth opened wide in shock at the realization that her little sister's boyfriend was ploughing into her pussy. 

Thankfully, right at the same time her climax overwhelmed her and she closed her eyes. Her mouth was still open, but in a silent scream of raw pleasure rather than of shock. She grabbed one of his hands on her hip and squeezed very hard as she fought to remain silent. Dustin could see that her climax was extremely powerful. Sadly for him, he knew that he was still a ways away form his own. And he had a feeling that this would stop very very soon. 

While he was still ploughing her delicious pussy, her climax finally waned and she suddenly pushed him away. Standing in front of him, his erect, dripping wet, turgid and twitching cock between them, she frowned at him, clearly angry. "What the fuck is wrong with you?" she asked, whispering. 

"I didn't know it was you!" he replied weakly. 

"You didn't know? How the fuck could you not?" she asked, her body trembling with a mix of anger and post-coital spasms. 

"Well, I figured it out eventually, but..."

"But decided to keep on fucking me anyway?" she sighed angrily. "Are you insane? You think I believe you? I know you've been lusting after me for years! You're just using this excuse!"

"Stop it Hayden!" Dustin said, some of his own anger stirring up. "You didn't even realize it was me even if I have a bigger cock than your boyfriend! And even if I can make you climax in minutes!"

Hayden stared at him, stil shaking and breathing hard. And then something clicked in her head. She backed away until her ass was pressed against the counter and hopped on. She then lifted and spread her legs. "If you can make me cum one more time, I'll keep this a secret." she growled. She was covered in sweat, her hair tangled and damp all over her skin and she was breathing hard, still intoxicated with lust. 

Dustin didn't wait a single second. He closed the distance, guided his cock into her and sheathed himself once again. "Oh my gods!" she moaned as she wrapped her arms around his shoulders. "That is such an amazing cock!" Grabbing her ass in his hands, he pulled her against him. Since she was grabbing him, he couldn't push with his legs and so worked with his pelvis. It seemed to work wonders. Hayden was groaning once again, as if she were already on the way to another climax again. 

Feeling his own climax finally coming closer, Dustin knew he had to think of something. And then it came to him. Without warning he pulled completely out of her pussy and knelt in front of her. The counter, and so her pussy, was just at the right height. Hayden had just enough time for a gasp before Dustin closed his mouth on her pussy. He felt her hands on his head almost immediately and even though her hands were covering his ears, he heard her moaning as he ate her out. 

It quickly became obvious that Hayden loved the same thing as her sister. And since her sister had often told him exactly what she liked... well, let's just say that Hayden was shocked by his prowess. "Fuuuuuuuck!" she whispered after moving her hands away from his ears. "You fucking bastard, you're going to make me cum again! Damn! My boyfriend never wants to eat me once his cock has been inside me..." 

Dustin was grinning as he ate what turned out to be his second pussy ever. His first girlfriend hadn't been into oral at all, on her or on him. Hayden, like her sister, tasted absolutely delicious and he was enjoying himself immensely. "Want me to eat you until you climax?"

"Fuck yeah!" she replied, looking down at him. 

"Only if you do the same for me," he replied before plunging back in. 

"Bastard!" she growled. "Ok, I will. Just don't stop!"

About five minutes later, with his face already covered by her juices, Dustin felt her gushing a huge amount of fluid all over him. By then Hayden was bucking wildly on the countertop and Dustin feared that someone would hear them. She gripped two fistfuls of his hair as she climaxed. Once she relaxed, she pulled him up. Before she could gather her breath to talk, he slipped his cock right back into her spasming pussy and resumed fucking her. "Didn't you wanna cum in my mouth?"

"Oh yes, and I will. But I wanted some of that sweet pussy one last time."

"Did I... Did I just squirt all over you?" she asked hesitantly. 

"You sure did! I don't mind," he replied. 

Hayden laughed and leaned backwards, holding her body with with her hands. It enhanced her breasts, which bounced with Dustin's thrusts. Soon Dustin was feeling the edge of his orgasm beginning to crest and he pulled away. Without hesitation Hayden jumped on the floor and knelt in front of him, her mouth opened. Dustin's eyes opened wide seconds later when he realized just how good a cocksucker his girlfriend's sister was. 

In so much less time than he would have liked, Dustin felt his climax finally exploding. Looking down and staring into Hayden's eyes, he felt his sperm spurt down her mouth and throat as she swallowed everything he gave her. It was his turn to shake and tremble as he emptied his balls into her mouth. 

Eventually he was spent and she stood up, licking her lips. Standing in front of him again, but this time looking a lot calmer, Hayden looked at him and asked "Why didn't you stop when you realized your mistake?" 

Dustin shrugged and said "This was my one chance of fucking the most beautiful girl in the world... I was not going to abandon it."

Hayden smiled, shook her head and rose on her toes to kiss him on the lips. Before leaving the kitchen, she paused and turned around, staring at his still hard cock. "Damn... My sister is one lucky girl!"

"Hayden!" he whispered before she could leave. "I didn't get to kiss your breasts..."

With an expression Dustin couldn't quite decipher, she paused for a moment and said "One day, in the future, you'll have the right to ask me to suck on my breasts. Once. And just my breasts. No fucking or anything else. Five minutes of sucking and caressing my naked breasts. Deal?"

Dustin didn't know what he had to lose, so he agreed. 

He ended up going back to his girlfriend's room and sneaked back into her bed. She woke up and asked him where he had been. As he was inventing a story, she grabbed his cock and giggled. "Get on your back, I've been waiting for round two!" Second later she was impaled on his cock, her juices mixing with her sister's, as well as her sister's saliva. When he finally came, Dustin felt an almost equal amount of pain and pleasure. That night would forever remain one of his most cherished. 

Back at the lodge, on his bed, he was grinning like a fool. He had to get rid of that erection before he could join his family, but the trip down memory lane reminded him that he had never collected on Hayden's promise. He took a mental note of it and decided to do something about it once back home. 

The next thought that popped into his mind was the fact that he would have to deal with the dreaded ball. A nudist ball, where naked men were expected to dance with naked women. And naked guys with naked girls. Last year he had managed to escape from that particular event, but only by swearing, to his mom, that he would do it the following year. That meant this year. Well, that thought chased the rest of his erection away. 

He got up and headed out to break his fast with his family, already trying to come up with a plan to avoid the ball again. At this point in time, Dustin had no idea that the two accidental penetrations of his sisters, as unlikely as they had been, would only be the beginning of a ridiculously lucky series of accidental penetrations at the nudist colony. Nor was he aware that the dreaded ball would have some utterly unexpected benefits as well. Unexpected in the sense of accidental...

On the morning following his accidental penetration of his older sister's pussy, Dustin walked down to the common room where his family shared their breakfast. Back home, in the real and clothed world, such meals with everybody present, nobody in a hurry and nobody on their cell phones were virtually non-existent. At least not for ordinary days. They often met to celebrate birthdays and other holidays, but it wasn't a regular thing. 

The meals back home were also different in another way: nobody was naked! By now, this was the beginning of their fourth day here, Dustin and the rest of his family were very much at ease with nudity. Strangely enough it was harder for Dustin to get used to seeing his father naked than his three sisters and his mother. He had no idea why. But even that discomfort was pretty minor by now. 

As breakfast was nearly over, Dustin's mother reminded him of something that was, in fact, a huge discomfort. The dreaded ball. For some reason or another that Dustin couldn't figure out, this nudist colony held grand balls on a weekly basis. Obviously people didn't go there dressed in gowns and tuxedos, but they handed over some small items of clothing (like garters, veils or high heeled shoes) to try to add some elegance to the whole thing. 

Not only did this colony held balls, but they insisted on their importance. While Dustin was comfortable enough walking around naked while surrounded by many naked girls and women, the idea of dancing while in the nude? And it was not just the random twitching that passed for dancing in clubs. Oh no. Waltzes and other fancy dances he didn't even know the names of. And always with the couples holding on to each other. Very closely. In some of the dances he had seen last year, the two partners were pretty much hugging each other. 

Maybe if Dustin had had a girlfriend with him... But then again, at twenty years of age, holding your girlfriend in a naked hug pretty much meant an erection. Doing it with a strange and beautiful girl? Impossible! The shame of feeling your erection growing without being able to stop it because it kept rubbing against a deliciously naked thigh? Oh the shame!

The last time he thought about it, he wondered if any of his sisters would agree to dance with him. But now that he had fucked Emily and Erica, those two were even more dangerous to his erection than beautiful strangers. And given that Lily was Emily's twin, Dustin didn't think that it would make much difference. And his mother would dance with their father, of course. Fuck! 

So when his mom asked him if was ready for the ball, that would happen tonight, he shook his head and buried his face in his hands. His dad slapped his shoulder and told him to man up. Erica, on the other side of the table, laughed and said "That's exactly what he's afraid of!" As the other members of their family got the joke, they all laughed. 

Dustin covered his face again and said "Is this ball a conspiracy to humiliate young men?"

They spent another fifteen minutes trying to tell him that it wouldn't be too bad, but Dustin wasn't so sure. With the others all gone to various activities, Dustin was left alone with his mother. And her breasts. "Damn they're so fucking huge!" he thought. "If Hayden had 34D bras and Erica's breasts were bigger than hers and in turn his mother's breasts were bigger... Shit!" 

On one hand he had seen lots of obese women with ridiculously large breasts that defied his ability to imagine bras that could contain them. Not only that, but those fat breasts looked like large flat pancakes resting on their huge bellies. Nothing erotic there. "Maybe," Dustin thought. "Maybe I could get one of those women to dance with me?" But he dismissed the thought. 

His mother had very large breasts, but she wasn't obese! Well, she probably landed in the overweight category but only because of the extra pounds she carried in those breasts. If Erica reminded Dustin of the pin-ups of the fifties, he was pretty sure his mother could have been one when she was younger. Even at her age, in her mid-forties, her breasts were still proud and hadn't lost the fight against age and gravity. 

He closed his eyes and tried to think about something else. "Tell you what..." his mom said as she stood up. "Why don't we practice dancing?"

"It's not the dancing that worries me. I should be able to pick that up easily enough." he replied. 

"I know. You're an excellent dancer!" she said with a smile, a typical motherly comment. "But why don't you try dancing with me in the nude?"

"What?" Dustin said after swallowing. 

"Why not? That would allow you to get used to the idea. Remember how uncomfortable you are during the first day of being here? Maybe it could work the same way."

"Mom! That's a terrible idea. Thanks, but that will never work!"

Frowning, his mother sat next to him and placed her hand on his shoulder. "Why not?"

"Mom! Please!" he felt himself flushing and didn't know where to look with his mom so close. 

"What is it? Are you ashamed to dance with your mom?" she asked, a sweet smile on her face. 

"No. Not at all..."

"So, what is it?"

Dustin sighed. "Mom... When I imagine myself dancing with a pretty girl and then I get..." he paused and coughed, really uncomfortable suddenly. "And I get an erection!" he added in a whisper. "I just can't imagine dealing with the shame!"

"The shame?" she asked. "It's just natural!" she sighed. "You're just over inflating the problem!" 

"Mom!"

His mother realized the unintended pun in her last sentence and laughed. Dustin relaxed and added "And if we go practice, what do I do if... if... if it happens with you?"

His mother's eyes opened wide and looked shocked at the thought. Not in a angry way, just a profoundly surprised way. "Oh, forget it mom... Thanks for the offer, but I guess I'll just have to die of shame tonight..."

"Stop it right there young man." she said in her authoritative voice. 

Dustin had realized very early, even when he was just a little kid, that his mother was the real authority in his family. When he heard that tone, he knew he had better turn around, otherwise there would be hell to pay. "Yes, mom?"

"Let's make a deal. Let's say you practice with me and do have an erection. First thing I promise is that it's going to be our secret. Second, if you can't learn to get it under control, I'll let you skip the ball."

Dustin stood there, looking right into her eyes. "You promise?"

"Yes. Do we have a deal?" she asked. 

"We do. When do we start practising so that I can forget about that damned ball?" Dustin asked with an impish expression on his face. 

"In one hour. In your room. We'll tell the others not to bother us for at least an hour. Private dance lessons for my son!"

"Great! See you then!" Dustin walked away, looking at his mother as she sat back down and sipped her iced tea. She looked perfectly relaxed and confident, as if dancing nude with her son was normal...

But Tessa wasn't relaxed or confident at all. She was, in fact, extraordinarily nervous. If she hadn't seen Dustin and Erica fucking last night, maybe she could have offered him dance lessons and maybe she would have been able to deal with any erections that might appear. But now that she had seen that and knowing that she hadn't been able to control her urge to masturbate at the sight of her son's cock ploughing into her daughter's pussy... Well, that was an entirely different matter. 

Tessa wondered if she had offered those lessons out of a genuine desire to help him, or out of genuine desire for him. "Damn it..." she thought. Would she really be able to handle it if he ever got an erection, and if it brushed against her thighs? Or pussy? "Christ!" she thought. "I'm in so much fucking trouble!"

An hour later, Dustin swallowed hard when he saw his mother walking into his room. He had been thinking about the fact that he would be dancing with his mom, their naked bodies entangled, her huge breasts against his chest... And now he had to force himself to tear his eye away from those two breasts as they swung and bounced as she walked towards him. 

"Don't look like you're about to be executed!" she chided him. 

"No, that's only later tonight..." he replied sullenly. 

"Pfff! Nonsense! After our practice, you'll be able to go to the ball with confidence. And if you don't already know this, you'll discover that girls melt for confident guys that can dance. Real dancing I mean."

And with that, she placed an old CD player on the table and pressed play. As she thumbed through a few CDs, Dustin looked at her. Besides her very delightful body, his mom had another stunning feature: her hair. While he knew that she often used shampoos that enhanced their color, their natural red was stunning on its own. Maybe a bit darker than the very bright red that some redheads had, but still remarkable enough. But besides the color itself, Dustin's mom had a very thick mane that she kept very long, all the way to the small of her back. And in front, there was a matching red patch of hair above her pussy. Wider than Erica's strip, but stil carefully trimmed as well. 

After she pressed play an old tune, Dustin guessed that it was from the 40's, began to play. His mom then pushed the bed and the sofa away to clear up some space. After that, she looked at him and extended a hand. After a long sigh, Dustin got up. "Remember our deal. If I humiliate myself in front of my mother and can't control myself, I don't go to the ball. Right?"

"Right." she confirmed. "But you won't humiliate yourself, even if you do have an... an involuntary reaction." As she took his hand, she looked straight into his eyes and said "Let me make that clear: if it happens, just ignore it and I'll try to do the same. Just work your way through it. I'm not some girl you don't know and I won't panic if it happens."

Tessa saw her son nodding, but could also see that he was barely managing not to run away as it was. "Let's begin with a slow waltz. That way, if something happens, it will be trapped between our bodies." Her son mumbled his agreement. "You'll have to come much closer my dear." And with that Tessa pulled her son directly against her body, feeling his thighs against her, his cock against her lower belly and this chest against her breasts. 

Judging by his two previous girlfriends, Tessa believed that her son wasn't into large breasts, so that should lessen the threat of an erection. What she didn't know was that Dustin was discovering, more and more each day, that his brain was essentially programmed to like big breasts. 

In the end, the first dance went pretty well. Tessa felt that while her son's was really stiff, his cock was still soft. "Shouldn't it be the opposite?" she thought and then mentally swore at herself. "Soft and relaxed all around!" Out loud, between the songs, she said "You see, it wasn't that bad? Now, for the second dance, just relax. Forget about getting all the steps right and just flow with me."

"Ok... I'll try," he replied. 

And about halfway into the song, she felt him succeeding. He felt more like a living being rather than a wooden board and he looked into her eyes from time to time. He even smiled at her. But by the end of the song, she could definitely feel his erection against her thigh. And he froze as he felt it as well. "I'm sorry mom..."

"Shhhhh," she cut him off. "Don't think about it, it'll go away."

She didn't know if it was the case, but she certainly hoped so. For his sake and hers. Even if her own physical reactions to his presence weren't as obvious, Tessa could certainly feel her body reacting to him. She could feel a growing tingle between her legs. She took a deep breath and tried to think of anything else. And failed. Her mind felt like a ping-pong ball between his growing erection and her memories of him fucking Erica. 

Pulling his head closer against hers, she bit her lower lip and hoped for the best. Soon though, his erection became so hard that it was an impediment to the dance. Until then they had managed to keep it pointing downward, trapped between their thighs. Maybe if he moved away slightly, it could become less awkward? Tessa didn't know that she wasn't fully in control of her thoughts by then, didn't realize that if she released the pressure of her thigh against his, there was only one thing that was going to happen. 

And so she did it anyway. As soon as her son't cock was freed from the temporary trap, it flew straight up between her legs to slap noisily against her pussy. The wet quality of that noise was unmissable. Mother and son both gasped at the same time and she felt Dustin wanting to pull away. "No..." she said breathlessly. "Wait a moment. If the girl doesn't pull away, it means that she understands."

"But mom... This is... it's..."

"Practice. Nothing more," she replied. She hoped that he wouldn't notice that she was burning with lust, forbidden lust for her son and his cock. 

Dustin's mind was going in all sorts of directions at the same time. "How the fuck could she let me stay there, my rock hard cock rubbing against her pussy?" he wondered. He also realized that while this wasn't actually an accidental penetration, it came close enough to make memories of Emily and Erica pop into his head. Which wasn't, at all, a good idea. But more than that, he was fully aware that his erection had nothing to do with Erica or Emily and everything to do with his mom. 

Her breasts, so impossibly big and firm for her age, dominated his thoughts ever since she had walked in. But as he held her, he discovered that the generous curve of her hips and the feeling of her large rounded thighs against his were intoxicating as well. "How the fuck can I be attracted to so many different girls and women?" he thought. There was essentially nothing in common between his old girlfriend Niemira, his twin sisters and his mother. "Yet here I am, having erection left and right. And for my own sisters and mother! What the fuck is wrong with me?"

He listened to his mother's reassuring her, his overwhelmed mind not at all able to pick up her quivering voice, the fact that her body was now much warmer than it had been at first, nor even the fact that her pussy was slightly wet. He didn't feel any of that. All he could feel was his shame and confusion. 

"Listen Dustin... Let's try to forget it. Maybe it will go down?"

"Sure..." he replied, knowing full well that leaving it to rub against a pussy meant that it wouldn't go down in a hundred years.

Sure enough, by the time they were done with the next song, his cock was still rubbing against his mother's pussy. In this angle, especially since she was slightly shorter than he was, there was no chance of an accidental penetration. Still it was intoxicating and Dustin could feel his embarrassment and disgrace being eroded by his lust. Very quickly. Part of his mind even realized, finally, that her mother's pussy was wet and that his cock was now sliding very smoothly against her lips. 

When the next song turned out to be more upbeat, Dustin took a deep breath and decided to let himself have fun. He switched his grip on his mother's back, letting his hand slide much further down before grabbing her hand more strongly. And he began dancing more energetically. "If she's OK with my erection rubbing her pussy, then so be it!"

When Tessa felt her son's change of attitude and energy, she felt her heart reacting. Her heart and her pussy. She was already swimming in forbidden pleasure, her wet lips being endlessly caressed by her son's very nice cock. If anyone caught them doing this, there would be hell to pay. Yet, at least for a while, she abandoned herself to the moment and enjoyed the sensations. She pulled herself even closer to her son with her own hand on his back. 

Once and while their movements made it so that his cock on her pussy would make a wet noise after pulling away and coming back. They both moaned when this happened, but they didn't look at each other. In fact, the way their heads were positioned, neither could look at the other. Unconsciously, it seemed that despite their pleasure, they knew something strange was happening.

About two songs of this later, Tessa knew that they had to stop. This was just too much. She felt on the verge of a climax and was pretty sure that her son's cock was now dripping with her juices. Also, they were barely dancing by now. Instead, they were pretty much dry humping each other, trying to maximize their pleasure without going any further. "Any further than they already had gone!" she thought, biting her lower lip. 

As the next tune began, a very upbeat one, Tessa moaned one last time and pulled again. When her son's cock slipped directly against her clit she moaned and feared her legs would give way. Damn she was keyed up! She knew enough about herself and her sexuality to know that this was a very dangerous mood for her. In such a mood she had let her husband do things she would never have accepted otherwise. And now she wasn't with her husband, but with her son...

"Ok..." she groaned as she steadied herself. "Let's try another type of dance." 

At first, when she taught him a classic fifties' type of rock and roll dance, her desire quieted down. But then she saw his glistening cock moving this way and that. When their eyes met after they had both looked at it, they laughed together. "Well... That won't work at the ball!" Tessa said. She went to the CD player and switched the tune to a slower one. "Come here. Let's try a slow dance."

Dustin was very surprised by that suggestion. And indeed, when they essentially hugged each other, his cock pushed straight up and trapped between their bellies this time, they both moaned. Having seen his mother dancing to that old rock and roll music, shaking and twirling, Dustin had finally understood the near fanatical admiration men had for those very curvy women in the fifties. The pin-ups. Briefly he imagined his mom in an old-style bikini washing an old Corvette. "Fuck!" he thought, feeling his cock surging. 

And now, almost shamelessly, the two of them were caressing each other with their hands as they danced. And Dustin couldn't resist repeatedly pushing his cock up against his mother's soft belly. A few inches higher and he would touch her breasts! Damn it! His mother cleared her throat and said "Well, maybe this wasn't a good idea after all." This time he noticed her shaky voice and even her unstable balance as she walked to the CD player. 

When the music began playing, rock and roll again, she told him that he had to learn to make her twirl. "Yeah... As if seeing your body twirling around and your breasts flying will help..." Dustin thought. But in the end, he didn't get to see that very often. Only once in fact. 

His mother told him how to hold her hand and then the twirled away from him. At this point they were as far apart as they could be while still holding hands. "Ok." she said. "Now, let me do the work and just hold my hand as I come back to you." On the next beat she rotated twice as she closed the distance between them. She then was in his arms, but with her back to him. Her plan had been to move out again to repeat the series of steps. But sometimes the best laid plans...

What happened instead was that Dustin felt his cock nestling itself between her buttocks. And that was just too much. Reflexively, Dustin pulled away from her, hoping to disentangle himself completely. But his mother was holding onto his hand and was pulled backwards with him. They both lost balance and Dustin fell back on the sofa. And so did his mother. Right into his lap. 

And, because such was the way this week was going, his cock fully penetrated his mother's drenched pussy. Is it an accidental penetration when both of them wanted it?

They both froze, breathing hard because of all that dancing, their mouths opened in shock. Dustin was too shocked to do or say anything, but noticed that his mother didn't move away. At all. For an entire minute. A minute of silence while your mother is impaled on your cock, not moving, feels like an eternity. Until, finally she did start moving. 

Shock or no, Tessa knew she should pull away immediately. If she did, they could probably laugh it off and promise not to talk about it to anyone. But she didn't move. It had been more than two decades since she'd had any cock but her husbands in her pussy. And so this accident scratched that itch. Not only that, but it was her son's cock, the one she'd been fantasizing about since yesterday. "My sweet son's cock is inside me!" she kept thinking, repeating it in her mind as if on a broken record. 

She should have gotten up immediately. Should and could have. She would learn later that Dustin was too shocked to move. She wasn't. Instead, she was in perfect control of her body. And she decided to remain sitting on that fantastic cock. For a long time. Tessa couldn't turn around and look at her son. Couldn't think of anything to say either. A mother couldn't say "Wanna fuck?" to her son. Then again, she remained there, feeling his cock pulsing inside her. 

Instead she did the only thing she could: she rose up. But only so far as to keep the tip of his cock inside her. And then she lowered herself back down. And then up again, then down. In silence, without even looking at her son, she began fucking him. If that initial penetration had been an accident, and if that first minute could have been attributed to shock, nothing could explain away the fact that she was now riding his cock. 

They were fucking slowly in utter silence, as if not saying anything was making things right, somehow. In fact, the only thing breaking the silence were the soft, squishy sounds of his cock moving in and out of her pussy. It was utterly surreal. When she felt his hands on her ass and finally heard him moaning "Oh, mom...", Tessa closed her eyes and felt her pleasure being ratcheted up a notch. She was soon overwhelmed by the raw sensations and the sheer fact that she was fucking her son. 

Her thighs were opened wide around his and both her hands were on his knees, giving her leverage. And so she banished all thoughts of impropriety, of forbidden incest, of utter craziness and simply fucked her own son. "Gods his cock is wonderful!" she thought. "No wonder Niemira was always walking around with a grin on her face! It's not huge, just... just perfect!" Tessa remembered that she was echoing her own daughter's words about Dustin's cock and laughed. Laughed as she fucked her own son. 

Dustin, staring at his mother's large and perfectly rounded ass moving up and down on his cock, was on the verge of laughing as well. It was just impossible, accidentally fucking one pussy after another like this. One for every day except that first day. Impossible and insane. And yet here he was, fucking the most voluptuous woman he had ever see in his life. His mom. 

He was already mesmerized by the curves of her waist, hips, thighs and ass while she had her legs opened across his. Without a single word being spoken, she managed to let him know how to move. Second later he was the one with his legs opened and she had closed her between his. When this was done, his jaw dropped as this new position had three very powerful yet very distinct effects. 

The first was deeper penetrations. Even though his mom had been letting her entire weight drive her penetrations, her generous ass had prevented his cock from going as deep as it could have. But with his thighs out of the way, he felt his mother drive down at least an inch lower. That meant that the tip of his cock pushed deeper inside and he felt the walls of her pussy stretching around him. 

The second effect was that it allowed his mother to quicken her pace. Her hands were still brace on his knees, but the new position gave allowed her to control her movements a lot more. And so in addition to the wet sounds of his cock fucking her pussy, there was now they rising rhythm of her ass slapping his lower belly. The situation had already been amazing, and now it was going into overdrive!

And the third effect was the way her ass now looked. By clamping her thighs together, Dustin's mom had involuntarily positioned herself in the most flattering way imaginable. Flattering and sexy. If he had begun to understand why those pin-ups from the fifties drove so many men wild, everything seemed to click in his mind. 

From then on his hand went back and forth between holding her and caressing her, sliding down those rounded thighs and back up to that small waist and down again to squeeze those two big buttocks. Dustin didn't know how long they remained this way. But eventually his mom stood up, turned around and straddled his lap. A second later she had impaled herself one more time and immediately began grinding her pussy against him. 

They both shared a glance, but his instincts quickly took over and he leaned forward to take the offered breasts. And it was a revelation just as momentous as seeing her ass earlier. Dustin feasted on his mom's breasts with more intensity than he had probably done as a baby. He grabbed the heavy breasts with his hands, lifted them up and brought those mouthwatering nipples to his mouth. 

Dustin could barely believe how big her mom's breasts were. He had seen a few nude models with what looked like bigger breasts online, but still, not a lot! He became convinced that his mom could have made a lot of cash as a nude model when she was younger. But he forgot about that thought and tried to satiated his need for those mammoth breasts. 

So focused was he on those breasts that his climax took him by surprise. In shock, he threw his head back against the couch and his mouth opened wide. He felt his mother increasing her tempo again as waves of pleasure shook him. He didn't even think about asking her to pull away and felt his sperm filling her pussy like consecutive explosions. He heard his mother beginning to laugh and gasp. Opening his eyes, he saw her face contorted by pleasure as she climaxed as well. She was pounding him into the sofa and soon buried her face into his shoulder as she came and came. 

Eventually Tessa collapsed on him, afraid that she would faint from all that pleasure. Sex with her husband was still very nice, but this was utterly different! She let herself fall sideways to the sofa. Her son's cock made a loud and wet plopping sound as it slipped out of her and they both laughed. In this post-coital bliss, they smiled at each other and remained that way for a few minutes. After that, Tessa reached for his cock, pretty much completely soft now, and said "See? I knew we would find a way for you to control it!" 

"Wanna bet?"

Tessa was surprised about her son's comment. She was even more surprised when he stood up and invited her to dance. She realized that she had forgotten what it meant to have a 20 year old lover. Within a minute his erection was back and she knew she was in for another round. This time, when his erection pressed on her pussy, she purred like a cat and hugged him harder. She knew she wanted it inside her again, but there was a gift he wanted to bestow upon him first. 

Slowly, languorously, she lowered herself until she sat on her feet and ended up face to face with his very hard cock. Grabbing it by its base, she pulled it down, opened her mouth and took him in. The sudden feel and taste of her son's cock inside her mouth reignited the flames of her pleasure almost instantly. After a minute, she had licked, sucked and swallowed whatever traces of her juices had remained, and from then on, it was nothing but Dustin. The taste of Dustin's cock. 

Even though she could see that her blowjob was having its intended effect on her son, that wasn't quite the gift she had in mind. She rose up on her knees and, after spitting a large wad of saliva on his cock, wrapped her breasts around his shaft. Looking up, she said "I bet you've never experienced this..." 

Dustin could only shake his head as he stared, unbelieving, at the tip of his cock appearing above her breasts. And then disappearing, only to reappear again. As wonderful as her pussy and mouth had been, this was something else entirely. He had seen countless of videos of big breasted girls doing this online, but had never lived it before. Hayden, and now his older sister, could have done it, but it just didn't happen. 

Dustin gasped and shook as he fucked his mother's breasts, unable to believe that regular kin could feel about as good as a pussy! Pussies had evolved for millions of years to be as pleasurable as they could for a man's cock. Breasts had evolved for an entirely different reason. And yet... "Christ in heaven!" He couldn't believe just how incredible it felt!

If he hadn't just climaxed, Dustin probably wouldn't have last more than two minutes. But since he just had, as well as having had sex twice in the two previous days, he was able to enjoy this unique pleasure for a long while. He knew he could control himself and stay like this for hours. But as the minutes flew by, he also knew he wanted to fuck his mom again. 

And so he grabbed her shoulders and pulled away from those miraculous breasts. Once she was standing up, he pushed her until she fell on the bed on her back. As she was giggling, he jumped on her, slipped between her thighs and found her pussy again. And so Dustin began fucking his mom again. 

This time, even though they weren't talking anymore than the first time, things were different. Neither of them found themselves in this singular desire and self-reproach tension that had characterized the minutes following their first accidental penetration. Oh no. Instead, they were kissing passionately like mother and son never should. But they were. They were kissing madly. 

Their climaxes rose pretty much at the same time once again and they held on to each other as if their lives depended on it. It was a wonderful experience for Dustin, where his love for his mother mixed nicely with the lust he had finally released. About ten minutes later, each of them on their backs in bed, his mom grabbed his hand. "So, about the ball..." and they both laughed. "But seriously. I have found the perfect solution. Fifteen minutes before it starts, come to my room and I'll let you fuck my breasts again."

"Just fifteen minutes?" he replied, a naughty gleam in his eyes. 

As Tessa watched her songet up to take a shower, she smiled. She was remembering something that had happened so many years ago. It was in her nude modelling days. Thankfully, that was in a pre-internet world and none of her images had ever popped up on the net. Not even her husband knew about them. But once, after she had agreed to let a male partner touch her pussy with his cock, things had taken a surprising turn...

***

Much later that night, after having taken up on his mom's titfucking offer, Dustin walked in the main hall where the ball was held. On his arm was his younger sister Lily. And as they walked under the fake trees with their garish flowers, she leaned towards him and whispered "Emily has told me a very surprising story, big brother..." Dustin froze for a moment, but took a long breath and kept walking. This... this complicated things. But then again, as he looked at her grin, he wondered if it was not an opportunity.
