Stud Son, Jealous Mommy

A note: My stories aren't for everyone. If you don't like women with really huge breasts, mother-son incest (or the use of the word "mommy" in a sexual context), discussions of hypersexuality, and totally unrealistic scenarios, they might not be for you. If you like those things, great! But I can't stress this enough: ***These scenarios are not meant to be realistic.*** At all. They exist in a fantasy world. If that, or anything else I've mentioned, is not your thing, there's plenty of other stuff to read on this site. If it is, please rate and leave a comment! Thanks. (All characters are over 18 years old.)

Many, many thanks to TheLobster for the eagle-eyed beta-read.

On a sweltering early summer day, Betsy Pepper sat in the waiting room of her local train station. She nervously smoothed out her dress, a frumpy patterned number that she had put on to look as inconspicuous as possible. Sweat clung to her back and chest. The train she was waiting for was late by just a few minutes, but her nerves betrayed something else.

Her son Brian was coming home from his junior year in college. He had left in the fall as a gangly and slightly awkward 20-year-old. He was an only child and she a single mom. But over the months he had spent at school, she got a sense that his life, and he along with it, were changing. Over their occasional Zoom calls, she saw how his body had filled out, how he had begun taking care of himself. He looked more handsome, more muscular, more charismatic. He had developed a quiet confidence. She found herself nervous talking to him, as if she were on a first date. It was an odd feeling for the 42-year-old mother.

An announcement came over the loudspeaker: His train was arriving. She got up and hustled over to the platform. Passengers spilled out of the train and she strained to find her son. At last she saw him, standing about a car and a half away.

She gasped.

He was stunning. Tall, visibly muscular under a tight black sweater, a gorgeous sweep of dark hair on his chiseled face. He looked transformed. She walked toward him, watching as he turned and reached with his hand into the train exit he had just descended from. A woman's hand took it; she emerged, just as Betsy came up to her son. She, too, was stunning: A 30-something beauty, petite, slim, clad in a tight, gray business suit, her auburn hair pinned back.

Petite, that is, excerpt for her chest. It was simply enormous, bulging out obscenely from her suit.

"Brian?" Betsy said hesitantly.

"Oh, hey Mom!" he said, a smile spreading across his face.

The woman pressed her body against Brian's.

"Thank you for fucking me, baby," she said, her lips only inches away from his. Betsy's eyes widened and she suppressed another gasp.

"It was my pleasure," Brian said. They kissed, deeply and passionately. Brian's hand was suddenly on one of the woman's massive tits; he had somehow undone her buttoned jacket and snuck his hand inside it, and was now slowly groping a breast through the blouse. The woman's hand snaked down to Brian's crotch and began a massaging motion.

Betsy blinked. She couldn't believe this was all happening in public -- though thankfully, no one else seemed to take notice. And she couldn't believe just how horny it was making her -- and how jealous of the woman she was.

They broke off the kiss, but not the embrace. Betsy coughed.

"Oh, sorry. Mom, this is... I'm sorry, I actually don't know your name."

"Selena," the woman said, not taking her eyes off Brian, still massaging his crotch. "Nice to meet you."

"I... Nice to meet you too," said the older woman.

"Selena, this is my mother, Betsy."

"Oh, I see. You have a quite a son here, Betsy. How many times did we fuck, baby? Four? Five? Twice in the bathroom, right? And then right on the seat another couple of times. He's unstoppable. I've never had that many orgasms in such a short period of time," she said, patting Brian's crotch in an almost congratulatory way.

"I... um... I see. You made love on the train?"

"That's right. We tried to be discreet at first, but after he made me scream a few times, we figured: what's the point? No one seemed to mind."

Brian's hand was still groping her ample tit, which Selena's free hand had migrated to, encouraging him to continue.

"God, I want more." She pulled a card from her pocket and handed it to Betsy without diverting her gaze. "Whenever your gorgeous son wants to fuck me again, please have him call me." Betsy took the card. The duo kissed again. "Jesus, what a cock! So thick. And he knows how to use it. Ma'am, you should be proud you gave birth to such a fucking stud." She finally looked at Betsy, as if a trance had broken. "Well, nice to meet you!" She turned back to Brian. "And nice to have met you too, Brian. Brian, right?"

"Yup," he said flatly.

In the car ride home, Betsy had trouble keeping her eyes on the road. She kept looking over at her gorgeous son, who stared out the window indifferently. After few moments of silence, she said, "So... you had a good trip?"

"Yeah, fine. Pretty uneventful."

Odd choice of words, she thought. "But you, um... you made love to that woman? Multiple times?"

"Oh. Yeah, we fucked. She's got such a great body. Killer rack. Really huge."

"How did, um, that happen?"

"She was sitting across from me. Caught her looking. She bit her lip, plumped those huge tits. You know. Anyway, she got up to go to the bathroom and glanced back at me. Smiled. I followed. I fucked her up against the sink. And then bent over a railing. It was a little bumpy but we made it work. I watched those huge udders sway and jiggle in the mirror. Got back to our seats. She climbed on top and fished out my cock. Like she said, we just started fucking in front of everyone." He shrugged. "Anyway, how have you been?"

Brian dropped his bag in the living room and looked his mother up and down. "You look good, Mom. You've put on a little weight, but it suits you. Not sure about that dress, but you do you. Anyway, I'm going to head up, jerk off a couple of times, and tap a nap. I'm wiped out." He kissed her on the cheek and headed up the stairs.

Betsy was speechless. She felt flushed. Did she have a fever? She followed her son upstairs. She heard him in the bathroom, and was about to knock on the door but noticed it was slightly ajar. She peered in and saw her son, buck naked, staring at himself in the mirror. His entire muscular body was tensed, his hand wrapped around his absolutely enormous penis. It was long, but also wildly thick, like a soda can, and covered in veins. Was it... it was, she thought: visibly pulsing. His tight ass flexed over and over. Sweat began to bead on his perfect skin.

Goodness, Betsy thought. He looked like a sex god.

He was mumbling to himself, his eyes closed. His muscles tensed even more, his hand a blur as it whipped up and down his enormous girth. Rope after rope of cum shot out of him, arcing through the air before splattering on the mirror. The sounds ricocheted through the room: Splat! Splat! Splat! Betsy momentarily worried the mirror might shatter.

After he was done, Brian turned around and caught Betsy staring at him. He smiled. "Oh hey, Mom. Man, I really needed that." He picked up a t-shirt from the floor and wiped the slickness from his cock. "I sort of have to cum multiple times a day. Hope that's not a problem. Hey," he said, nodding his chin at the mess dripping down the mirror, "you don't mind cleaning this up, do you? I'm gonna take a nap." He walked by her, again kissing her on the cheek, his huge, now flaccid cock slapping against her dress as he passed. "Love you!"

In a daze, Betsy picked out her fluffiest, most expensive towel, and began to clean up her son's massive cum-dump. Though she pursed her lips at first, annoyed at the request, she found her pussy was wet. As she cleaned up his cum, she imagined it all over her face and body and shuddered in a mix of pleasure and jealousy.

When she was done, she went to her bedroom. She stripped off all her clothes and stood in front of the full-length mirror on the back of her closet door. She had gained weight over the year her son was away. Not a lot, maybe 10 or 15 pounds. But what she saw was still impressive. She was beautiful. Long, light brown hair, a delicate face and neck. Like the woman on the train, she was petite, just over 5 feet tall. But her body was curvy - curvier than it had ever been. Her butt had swelled and she had a small paunch in her midsection.

And her breasts had grown. Just a year before, they had been an DD cup, but now they were bigger and heavier. She had graduated to an F cup and it was bursting at the seams. She plumped them and played with her nipples, one hand traveling down as she began to play with her clit. Imagining her son masturbating himself, it wasn't long before she, too, orgasmed, juices trickling down her legs, which almost gave out. She cried out as she came, then bit her lip to get herself to stop. Surey he had heard her... She got into bed and, reaching down under the sheets, again masturbated herself to orgasm, stifling her cries with her free hand.

***

The next morning she was making coffee, wearing a thick, shapeless robe when her son came down the stairs, still rubbing the sleep from his eyes. He put his hands on her voluptuous hips and kissed her on the cheek.

"Morning, Mom." He stretched, and she again admired his muscular, sinewy body -- and the bulge in his shorts. He caught her looking and she turned away.

"Don't worry," he said flatly. "Already jerked off this morning. What's for breakfast?"

"Eggs and bacon," she said, staring at the scramble in front of her. She tried to think of anything besides her son's huge cock.

"Hey," he said, pouring himself coffee before settling into a chair at the kitchen table, "you said we could go shopping, right? I need to get some new clothes."

Betsy nodded. She had won a sizable settlement in her divorce and had money to spend, so a splurge-y shopping trip was doable.

"Of course. I'm sure your... style is... evolving. Where do you want to go?"

"The mall is fine."

That afternoon, in the department store inside the mall, Brian was looking at a shirt and rubbing the cloth between his fingers. Betsy was trying not to overtly eyeball his body, and was failing at it spectacularly. In her peripheral vision, she saw a young woman doing the same. She was adorable: petite like Betsy, wearing a slightly nerdy combo of a corduroy shirt and sweater, which wouldn't normally have been tight but for the huge, round breasts that jutted out underneath. Extremely long, silky dark-brown hair tied in a ponytail; a sweet, innocent face.

She pushed a pair of round glasses up her nose as she stared at Betsy's son. She looked, Betsy thought, a little like Velma from Scooby-Doo -- if Velma were extremely busty.

The girl walked up to Brian, taking a deep breath, unintentionally (or maybe not) thrusting her huge tits out in the process.

"Excuse me," she said, her voice cracking a bit. Now that she was closer, Betsy could see that she wasn't just cute, she was beautiful. And that giant rack, which swayed back and forth as she nervously twisted her body.

"Hey," Brian said, turning without any reaction.

"Hi." The girl twisted a strand of her hair that was draped over her shoulder. "I just wanted to say hi. I'm Natalie."

"Nice to meet you, Natalie," Brian said, holding out his hand. He was staring directly at Natalie's enormous chest. She didn't seem to mind. "I'm Brian."

"Hi, Brian. I just wanted to say... you're incredibly beautiful."

"Thanks, Natalie," Brian said, without affect, his gaze finally rising to meet hers. "I appreciate that. You're very lovely yourself."

Natalie blushed. Betsy's eyes darted between the two. The erotic tension was palpable.

"I just... um... if you ever want to... god, I can't believe I'm saying this... if you ever want to... have sex... I'd love that." She was now pressing her huge breasts into his chest, staring into his eyes. "You can do anything you want to me. You can fuck me however you'd like."

Betsy wanted to say something, anything, about how inappropriate this was and how shocked she felt. But she was paralyzed, frozen where she stood, as if she were simply watching a movie and not present there in person.

A very erotic movie.

"That's quite an offer," Brian said, pulling Natalie into his body, his lips only inches from hers. "I'd love to take you up on that right now. Fuck you in the changing room. Pummel your little pussy over and over with my huge cock. Play with those huge tits until they're bruised." He leaned in and kissed her, gently, putting a hand on the back of her head Then he leaned back, and his fingers traced an outline down her neck and around one of her huge tits.

Both Natalie and Betsy were panting lustfully, rubbing their legs together. Betsy noticed a trickle of girl-cum making its way down Natalie's shapely legs. It was all the mother could do not to masturbate right there in the men's section.

Suddenly Brian let go of Natalie, who wobbled a bit, as if she were dizzy. "But, unfortunately, I'm shopping with my mom," he said, as if it were the most normal thing to say at the moment. "So we'll have to do it another time."

"Oh." Natalie turned to Betsy, a dazed expression on the young woman's face. "Nice to meet you," she said, almost slurring her words. She turned back to Brian and gave him her phone number. He promised to call her. She staggered away, her shapely ass wobbling under her skirt.

Brian went back to checking for his size on the nearest rack.

"What... what was that?" Betsy asked hesitantly.

"What do you mean?" Brian said, with a genuinely confused tone in his voice.

"You... That woman just offered to, um, have sex with you."

"I mean, technically she offered to be my sex slave."

"Does that, uh, happen often?"

He shrugged. "It happens. What can I say? Women like me." He held a shirt up to his impressive torso. "What do you think? Good fit?"

Betsy opened her mouth to speak, to object to this insanity, but then just found herself nodding.

"I'll go try it on," Brian said. "Shit, I should have fucked that girl first, then tried on this shirt. Oh well. Hey, do me a favor and see if you can find a pair of jeans that might fit me."

What the hell was happening? Betsy thought, watching her son's tight butt as he walked toward the changing room. When did her son become an actual sex god?

They spent the next hour or so wandering the mall. Betsy was now alert to the glances and leers Brian was getting wherever they went. Women, from teenagers to middle-age wives shopping with their families, all bit their lips, fanned themselves; and one check-out girl, at the frozen yogurt stand, even furtively snaked a hand down her pants when Brian smiled at her.

As they were about to leave the mall, Betsy heard someone calling Brian's name. They both turned around to see a teenage girl running to him at full speed. He barely had time to put down his bags before she jumped into his arms and began to kiss him on the lips and all over his face.

"Oh my god! Brian! I can't believe it's you!"

"Jenny?" he said, putting the teenager down. "Wow, you've really grown up! Let me take a look at you."

Jenny? Betsy thought. The neighbors' teen daughter that Brian had babysit a few times while he was in high school? This couldn't possibly be her.

"It's me!" the girl said. "Eighteen and all grown up." She twirled around and showed herself off. What had been a scrawny, awkward young teen body was now wildly voluptuous: slim legs perched on four-inch heels, a full bubble butt pushing out a white tennis skirt, and a cut-off t-shirt bursting with two enormous, round teenage breasts. An innocent face with a sweet smile. She wore her blonde hair in high pigtails. She might have been 18, but her proportions and outfit were downright pornographic.

"You look amazing!" Brian said. "You've really filled out."

"Damn straight!" She shook her tits back and forth. "Growth spurt! FF-cups!" She looked Brian up and down. "You look amazing too. Jesus, you look fucking hot!"

"Thanks, kiddo. Hey, you remember my mom, Betsy, right?"

"Oh! Yes, of course. Nice to see you again, Mrs. Pepper," the gorgeous teen said, reaching out with her hand. Betsy shook it, and Jenny went straight back to Brian, engulfing him in another hug, which she didn't break. Betsy could see her huge tits bulging out against his chest.

"God, I can't believe it's you," Jenny said, stroking the back of his hair. "I always had a crush on you, you know. You were the first boy I ever masturbated thinking about."

Brian laughed, as if this was just normal reminiscing over old times. "How about that," he said, and Betsy noticed that his hand had somehow made it to Jenny's full ass, where it was gently cupping a cheek.

"And you've gotten much, much hotter!" Jenny bit her lip. "Hey, I work over at the Hot Topic here, and I could really use your help getting some stuff, um... down from a high shelf. Any chance you could give me a little assist?"

"Of course! Mom, you don't mind if I help Jenny out, do you? I'm sure it won't take long."

"It's pretty high up in the storage room. Might take a little while. To, you know, really reach it..."

"We're not in a rush. Right, Mom?"

"No, I guess not..."

"Great!" Jenny said. "Follow me!" She took Brian's hand and rushed off, her huge tits wobbling back and forth; Betsy had to jog to keep up.

"Right in here," Jenny said, pulling Brian into a side room of the store.

"Be right back, Mom," Brian said before disappearing.

"I... OK."

Betsy stood just outside the closed door. It wasn't long before she began to hear sounds: groans, moans, titters of laughter. Shoppers walked past, seemingly unaware of the increasingly intense noises.

"Oh god, Brian," Jenny's muffled voice said. "It's so huge!"

"Let me see them," Brian said, followed by a ripping sound. "Jesus, they're gigantic."

"Help me up onto this thing," Jenny said. "UH! FUUUUCK! SO FUCKING BIG!"

"I'm going to have to pound this thing to get to it."

"Do it, Brian! Harder! Please! More!"

More grunting and moaning followed. Betsy coughed nervously.

"THAT'S IT! YOU'RE THERE! GRAB THEM! SQUEEZE! PUSH! HERE IT COMES!!" Finally, a squeal and a muzzled scream.

More rustling, and then the door opened. Brian and Jenny emerged, visibly disheveled. Jenny was buttoning her top, her massive tits barely contained within.

"Wow, thank you for that... assistance, Brian. That was really amazing. I mean, you really helped me out there."

Brian was adjusting the bulge in his pants. "Hey, my pleasure. Just glad I could help you... get that stuff down from the shelf."

"You definitely reached there," Jenny said, blowing a long strand of blonde hair off her sweaty face. "You got allll the way up there."

She pulled him into a kiss, a deep one, their winded bodies pressed together.

"Well, gotta get back to work. Really nice to see you again, Mrs. Pepper! Call me, Brian." Betsy picked up the bags and handed them to her son.

"Thanks, Mom. Sorry about that. She really needed help with... the inventory."

"Uh-huh."

As they were about to leave the mall, they passed a woman sitting on a bench. She looked distressed. Two huge shopping bags sat morosely at her feet. She was breathing heavily, the heaves of her chest accentuating her utterly massive breasts, which spilled out over the top of her flowery sundress. She looked up with a pained expression and Betsy suddenly recognized her.

"Miriam?"

She lived down the street. Unlike Betsy, who had given birth to Brian when she was only 20, Miriam had a child late in life, after struggling to conceive for years. She and her husband had divorced over this, and she eventually had to use a donor. Betsy was surprised to see her without the infant.

"Betsy! Hi." Miriam wiped a tear from her eye. "Brian, is that you?"

"Hey, Mrs. Mulders. Are you OK?"

"I'm fine." Her lip trembled.

"You don't look fine. I mean, you look more beautiful than ever, but something is wrong, isn't it?"

The first part was true: she had barely aged since Brian had last seen her. He had had a crush on her for years, and she was a regular subject of his masturbation sessions.

He sat down next to her and motioned to his mother to sit down next to him.

Miriam began to cry.

"I'm sorry," she said between sobs. Brian started stroking her long brown hair.

"Hey, hey. It's OK. What's wrong? You can tell me."

"It's just... It's the first time I've left the house since little Monica was born. She's home with a sitter. I thought I'd just take a quick trip to the mall, but I ended up spending hours shopping. I feel terrible. I shouldn't have left my baby for so long."

"Miriam, you didn't do anything wrong," Betsy said. "You need time for yourself."

Brian wiped the tears from Miriam's eyes. "Yeah, Mrs. Mulders. You must've been lonely all by yourself for all these months."

"That's sweet," Miriam said. "But it's not just that." She glanced down at her giant, heaving bosom. "I, um..."

"It's OK, you can tell us," Brian said. "What's going on?"

"It's just... I haven't gone without feeding Monica for this long. Ever. And I, um, produce a lot of milk. My breasts are so swollen. Look!" She thrust out her huge udders, causing them to swell even more over the top of her dress.

"Let me see," Brian said. He moved her hands away and replaced them with his own, cupping the massive tits and gently squeezing them. Betsy couldn't stop staring.

"Wow, they really are swollen," Brian said. "And so heavy. It must be really uncomfortable."

"It is. I would have brought a pump, but I thought I'd be back by now. I don't know what to do."

"Maybe I could help," Brian said.

Oh lord, Betsy thought. He wasn't suggesting what she thought he was suggesting, was he?

"What do you mean?"

"I could help you relieve yourself."

"You mean... suckle?"

"Just to help you out. I mean, it's sort of an emergency, right?"

"I guess so. I actually happen to have a nursing cover." She pulled out a huge, apron-like covering from one of her bags. "I just bought it. They only had extra-large ones."

"That's perfect. Why don't I lay down in your lap and help you with all that milk?"

Betsy gasped. "Brian, I don't know if that's a good idea," she said unconvincingly.

"Mom, I'm just trying to help. Don't you want to help?" He turned to the lactating mother, and again cupped one of her enormous breasts; it was her turn to gasp. "You'd like that, wouldn't you, Mrs. Mulders?"

She nodded and stroked Brian's face. "You're so sweet for offering. And so handsome. You've really grown up, huh?"

"Never mind that," he said, unbuttoning the sundress, revealing a massively overstuffed nursing bra. He lay his head in her lap. "Mom, help her with the nursing cover. Good thing it's an extra-large. You might as well drape it across my body. It might look weird otherwise."

Despite her skepticism, Betsy found herself doing as her son asked. Miriam undid the front of one of her bra cups, revealing a swollen, erect nipple already dripping with milk. Betsy caught a glimpse of her son latching onto it as she threw the nursing cover over him. Immediately, Miriam groaned in a mix of maternal and sensual pleasure.

"Ohhh god, Brian, this feels amazing." She snaked a hand under the cover and began to stroke the back of his head. "Good boy..." Her eyes were closed, she was lost in a haze of relief. "Be a good baby for Mommy..."

Betsy's eyes widened, then darted around their surroundings. They were in a relatively isolated corner of the mall. Occasional shoppers passed them by, but none even glanced over.

"You're doing such a good job suckling, sweetie," Miriam said, her head lolling back. "You're being such a good boy for Mommy, suckling all her milk." She turned to Betsy, an almost hypnotized look on her face. "I always wanted a baby boy..." Another gasp, as she pointed out a bulge in the nursing cover. "Oh! sweetie. Are you being a little naughty baby? Let Mommy help you with that."

Betsy stared, frozen, as Miriam's other hand went under the cover, grasping at the bulge lying under it. Was the beautiful, super-busty, lactating neighbor really going to play with Brian's huge cock as he suckled at her massive tit?

There was rustling under the cover. "There we go. Goodness, Mommy's baby is SO big! How does that feel, Bri-Bri?"

A groan from under the nursing cover.

"Time to switch boobies, sweetheart. You're making Mommy feel so good."

Brian shuffled his body down a bit and Miriam gasped again as he, apparently, latched on to the other massively swollen tit. Betsy was still frozen, unable to object to the wildly inappropriate scene: her own adult son suckling their mega-busty neighbor as mall shoppers passed by. She felt her pussy getting wetter and wetter and desperately wished she could do something about it.

Brian's groans increased. "Is baby going to make a mess for Mommy? Good boy!"

The noises under the covers intensified, then stopped. Miriam pulled her hand out; it was slick with cum.

"Betsy, be a darling and get me some wipes from my bag?"

Betsy nodded and tried to hand them to her.

"Silly! I can't do it myself. Can you be a darling and clean me off while your son finished suckling?"

Shakily, Betsy nodded again, as she pulled out a few wipes and started cleaning her son's cum off the hand of her beautiful neighbor. What the fuck was happening? she thought to herself.

Soon, Brian emerged from under the cover, panting, his face wet with milk.

"Brian, that was SO helpful! I feel much better." She squeezed her breasts. "Much less swollen."

"It was my pleasure, Mrs. Mulders. Really."

"Oh, you have milk on your face. Let me get that for you."

She pulled Brian's face into hers and licked the milk off it. The licks soon morphed into kisses, their tongues darting into each others mouths. They were making out, Miriam's enormous breasts still on display.

"OK, all clean!" Miriam said, refastening her bra and buttoning up her dress. "Really good to see you, Betsy! And thank you again, Brian. Come by any time to visit. I mean it: any time."

"I definitely will," Brian said, fiddling under the cover before getting up. "All good, Mom? I'll get the bags."

As Betsy drove back home, her mind reeled. There was no question: her son had grown into a gorgeous, incredibly sexy young man. And women were visibly thirsting after him, throwing themselves at him: gorgeous, wildly busty women, from barely legal teens to middle-aged mothers.

Betsy needed a plan.

***

That night, lying in bed after masturbating three times in a row -- while listening to her son do the same -- she made an appointment for the next day with a trainer at the local gym. She also clicked on an ad she had seen repeatedly on Instagram. Breast cream, it read. Firmer, younger. In small letters at the bottom, the fine print: May cause significant and permanent swelling. She ordered three tubes.

The next morning, she walked into her son's bedroom. She found him slowly, languidly masturbating his huge, obscenely turgid cock.

"Sweetie, this isn't normal."

"What do you mean, Mom?"

"All this masturbating all the time... and, um, having sex with random women..."

"I don't see what the problem is."

"I'd like you to see someone about it. Just to make sure there isn't something wrong."

"Nothing feels wrong." Brian thrust his hips up toward the ceiling, emphasizing that he was still, in fact, casually jerking off as he spoke to his mother.

"That may well be, but I'm taking you to the doctor. I made an appointment with Dr. Leigh for this afternoon."

"Dr. Leigh? My old pediatrician? Mom, I'm a grown man."

"Don't argue with me, Brian."

"Fine... Shit, I'm gonna cum, Mom. Wanna watch?"

Betsy got flustered and fled the room, but stopped right outside the door, listening to her son continue to masturbate himself to orgasm. She thrust her hand under her panties and did the same, again stifling a scream.

At the pediatrician's office, the receptionist, a beautiful young woman around Brian's age, told Betsy that Dr. Leigh had retired.

"Retired? But I made an appointment with him."

"I'm sorry, Mrs. Pepper. I'm sure Dr. Powers will be happy to see your son."

"Dr. Powers?"

"Yes, she took over for Dr. Leigh a few months ago."

Brian stepped forward. "Cindy?"

The receptionist startled. "Brian?"

"You two know each other?" Betsy said.

"We went to high school together. I asked Cindy to the prom," Brian said, smiling. "She said no."

Cindy looked him up and down. "Obviously that was a mistake," she said. She got up and came around the other side of the counter. She was wearing a tight blue sweater that accentuated her large breasts, displaying plenty of cleavage, and a knee-length skirt. She wrapped her arms around Brian, feeling his biceps and chest as she pulled back.

"It's good to see you. You look amazing."

"Thanks, Cindy. You too. It's been a few years, huh?"

"Yeah, I'm just working here over the summer. I go to community college."

"Very cool. I'd love to catch up more."

"Yeah, me too." She traced her finger down Brian's chest. "Definitely. Whenever you like."

Betsy coughed.

"Sorry, why don't you too take a seat in exam room two. Brian is, um, a little --" she looked down at the bulge in his pants "-- big... compared to the doctor's usual patients, but I'm sure she'd be happy to make an exception. I hope I see you soon, Brian." She fluttered her lashes at him and smiled.

The mother and son shuffled into the exam room, which was decorated for young children: big pastel letters and animal cutouts on the wall, toys and stuffed animals scattered around the room.

"Mom, this is ridiculous."

"I'm sorry, Brian. I know it's odd, but I thought it would be Dr. Leigh. You've been seeing him since you were a baby and I figured it better be someone who knew you."

Brian sat down on the exam table, Betsy on a nearby chair. Soon, there was a knock at the door and it opened. A stunning woman entered, tall and slender, wearing a white lab coat,. Her black hair was back in a ponytail, round black glasses perched on her cute nose. She filled out the coat impressively -- a stethoscope hung between her massive breasts, which bulged out from the coat obscenely. Thick, shapely thighs emerged from a skirt that went down just below the coat.

"Helloooo, doctor!" Brian hollered.

Betsy was staring at the stunning, wildly voluptuous woman, just like her son was -- a trance broken only when the doctor extended a hand.

"You must be Mrs. Pepper. I'm Dr. Powers."

Betsy stood up and took her hand. "Nice to, um, meet you, doctor."

Brian hopped off the exam table and extended his hand as well. "And I'm Brian, your very happy patient."

Dr. Powers seemed taken aback for a moment. "Nice to meet you, Brian. You're a bit older than I expected. And a lot more handsome." She smiled.

"And you're absolutely stunning. Very different from Dr. Leigh."

"Well, thank you." She was clearly used to receiving compliments, though her gaze lingered on Brian for an extra beat. "Why don't you both take a seat and tell me why you're here."

"So..." Betsy didn't really know how to begin. "Brian is obviously an attractive young man --"

"He certainly is," the doctor interrupted, eyeing the 20 year old. "I'm sorry, please go ahead."

"It's just that he... well, he sort of blossomed this year while at school."

"Blossomed?"

"I started having a lot of sex," Brian said.

"Ah, I see. Go on."

"Yes," the mother said. "A lot of sex. With a lot of different women. They seem... very drawn to him."

"Well, I can certainly see why. He's extremely handsome. And sexy."

"Um, yes. It feels like it goes beyond that, though."

"I'm not sure I follow."

"Doc," Brian said. "I think what my mom is trying to say is that -- can I use blunt language?" The doctor nodded. "I fuck a lot of women. Basically I can fuck whoever I want, whenever I want."

"I see." The doctor walked over to Brian. "Well, this is beyond my specialization, of course, but I must admit I am curious. Perhaps you should strip down and I can perform an exam."

"Happy to," Brian said, pulling his shirt over his head.

"Should he get a gown?" Betsy said.

"I actually don't think we have his size," the doctor said.

"No need," Brian said, winking at the doctor, who blushed as Brian pulled down his shorts. His enormous prick sprung up; he was already hard.

"Oh my goodness!"

"Yes, that's the other thing," Betsy said. "He's extremely well endowed."

"Indeed he is," Dr. Powers said. She took the turgid cock in her hands and began to gently stroke it. "Very much so."

"I also masturbate a lot," Brian said. "Like, all the time."

"How many times a day would you say you ejaculate?"

"Gosh, maybe... seven or eight times? That's between the sex and jerking off."

"And would you say you produce a lot of ejaculate?" She began to jerk him off more quickly, her massive bosom heaving more intensely in her lab coat.

"Yeah, it's a lot. Huge amounts."

"And does it diminish over the course of the day?"

"Not at all. It's a lot. Each time."

"I see. Your penis is really throbbing, Brian. Are you close to ejaculating right now?"

"Not really. I have a lot of control over that."

"Well," the doctor said, letting go of the huge cock before unbuttoning her lab coat. "I think some visual stimulation might help, don't you?"

"It definitely would," Brian said, staring directly at the doctor's enormous chest, bulging wildly out of her tight silk blouse.

"Doctor!" Betsy said.

"Mrs. Pepper, please allow me to do my job," the doctor scolded, unbuttoning the blouse, revealing a massively overstuffed, frilly pink bra. She unzipped her skirt and stepped out of it. She took a hold of the cock once again and resumed her strokes. "My goodness, that's a lot of precum. How's that, Brian? Does looking at my body help?"

"It sure does," Brian said, continuing to stare. "Those are some giant tits."

"GG-cups," the doctor said. "You're not the only one who's well-endowed."

"God, this is humiliating," Betsy mumbled, staring at the wildly erotic scene in front of her.

"There's no reason to be embarrassed," the doctor said, pressing her bra-clad tits against Brian's shoulder, kissing his ear and his cheek, before licking his neck. "It's all perfectly natural. My initial theory is that Brian is hypersexual."

"Hypersexual?" Betsy asked.

"Indeed. It's something I only learned about in medical school, but it all fits. Enormous sexual appetite, exaggerated sexual characteristics, endless stamina and energy."

"But why are women so drawn to him?" Betsy asked, watching the gorgeous doctor run her hand down to Brian's ass and begin to play with his butthole as she kissed him deeply.

"It's hard to say," the doctor said. "Perhaps we can sense his hypersexuality."

"And why are they all so..."

"So what, Mrs. Pepper?" the doctor said, getting down into a crouch, eye-to-cock. She licked the tip of Brian's huge, pulsing cock as he groaned in pleasure.

"Why are they all so... busty?"

"Well, that I can't explain. Do you like busty women, Brian?"

"More than anything," Brian said, putting one hand on the back of the doctor's head, and reaching down with the other to grope one of her enormous breasts.

"Huge tits really turn you on?"

"They sure do. Giant, firm tits just like yours. They make me want to cum. In any hole possible."

"I see," the doctor said before letting Brian push his cock into her waiting mouth. "GLACK!"

"My goodness," Betsy said.

"It's OK, Mom," Brian said, his breathing increasingly in intensity. "Dr. Powers is just doing a thorough examination."

"Mm-hm," the doctor moaned, the huge cock stretching her mouth to its limit. Her hand migrated down under her panties, as she began to masturbate. Her head bobbed up and down on the thick cock in earnest. "UCK! UCK! UCK!"

"Shit, doc! That feels amazing!"

Betsy couldn't stop staring, eyes darting between her son's massive prick, popping in and out of the doctor's mouth, and Dr. Powers's immense tits wobbling in their barely effective bra.

The doctor pulled her head off the huge cock, panting, barely able to breathe. "Jesus, I've got to feel this thing inside of me." She scrambled to her feet and unhooked her massive bra, freeing her gigantic tits, then pulled off her panties. Her breasts jiggled and wobbled wildly as she hopped up onto the exam table and lifted her legs high into the air, exposing her visibly wet pussy. "Quick! Shove it into me, Brian!"

"Doctor!" Betsy yelped.

"Just -- AW FUCK! -- continuing the exam, Mrs. Pepper!" the doctor cried, as Brian impaled her with his huge cock. "Jesus! So fucking hot! I'M GOING TO CUM, BRIAN! I'M SO FUCKING HORNY FOR YOUR SUPER-THICK COCK! IT'S MAKING MY PUSSY SPASM! FUUUUUCK!!" As the orgasm took hold of her quivering body, she pulled his body into hers, her enormous tits squashed against his chest. She leaned back and shook her giant, swaying tits for him, goading him toward his own orgasm.

"Stare at my huge tits while you fuck me, Brian! Show me how much you can cum inside me!"

Brian roared as he erupted in the scalding hot doctor's pussy, slamming his cock into her.

Betsy slumped back onto her chair as Brian fell into the doctor's arms, their sweaty bodies pressed together.

"Well," the doctor said. "I think hypersexuality is our diagnosis here." She kissed Brian deeply, then moved him out of the way and began to get dressed.

"What can be done, doctor?" Betsy asked.

"Nothing."

"Nothing?"

". He's fine. He just needs to fuck. A lot. Encourage him, Mrs. Pepper, perhaps with additional visual stimulation. Allow him to masturbate at home." She took Brian's face in her hands. "My office door is always open. And Cindy will give you my home address on your way out. Feel free to stop by whenever you'd like. And I'm sure Cindy would be happy to volunteer as well." She kissed him a final time, then strode out the door.

"I guess that's that," Brian said.

Betsy pursed her lips. She had to come up with a better plan. And, indeed, it was already in motion.

***

Two weeks later, Betsy was staring into her mirror as she dutifully applied the tit cream she had ordered online. She was rubbing her breasts, circling her erect nipples and moaning with pleasure. She reached down and began to apply it to her inflamed, moist vagina, It wasn't one of the indicated uses, but she found it increased her sensitivity down there -- and the intensity of her resulting orgasms.

This is how she masturbated now: looking at her own body, enjoying her swollen, enormous tits as she played with her throbbing clit and dripping wet pussy. Because how could she not touch herself? Everything was on fire. Her breasts had firmed up -- they were as taut and round as they had been 20 years before. They were also bigger. Much bigger. She had to throw away her F-cup bras, then the G-cups that she got to replace them. She was busting out of her H-cups. She loved having enormous breasts, even as she continued to hide them under loose sweaters and unshapely dresses.

She had also firmed up her body. She had worked out two to three hours a day for the last month or so. She knew she was in part sublimating her lust for her son. He was off doing whatever he wanted, probably fucking half the town. Any woman he wanted.

And she couldn't help but to ask him about it.

A few days after their trip to the mall, he returned from a day out. She was on the couch, reading a novel. He was about to go upstairs, but she couldn't help herself.

"Brian, come talk to me for a minute."

"What's up, Mom?"

"Did you..." She could barely get the words out. "Did you... fuck anyone today?"

"Sure did," he said nonchalantly. "A couple times."

"Who did you fuck?"

"Well," he said, sitting down across from her. His legs splayed out and she couldn't stop herself from staring at the bulge in his jeans. "This morning, I fucked Mrs. Patterson."

"The librarian?! She's older than I am."

"That's the one. So? She has an amazing body, for her age -- hell, for any age. You wouldn't know it from how she dresses but she's really curvy. A little pudgy, but hot as shit. Huge tits. And what an ass! Pretty, too."

"Where did you fuck her?"

"In the library."

"In the library?"

"Yeah. I was looking for a few books I need for a summer project. I was pretty hidden between the stacks; she was sorting books from a cart. She saw me, but didn't say anything. She just looked over her shoulder and winked, then pulled down her panties. I walked over, bent her over the cart and took her from behind. Man, was she wet. I slid right in. She had two orgasms pretty much right away. I eventually turned her around and plopped her onto the cart. Fucked her that way, playing with those huge tits. She kept saying she loved me. I'm not even sure she knew who I was. Anyway, I came inside her, then wiped my cock on her dress. She was a dripping mess."

Betsy's pussy was already so itchy and wet, it was all she could do not to play with it in front of her son. But she had to continue her queries. "Who else did you fuck?"

"Some random woman on the bus home."

"A random woman? On the bus?"

"Yeah, I have no idea who she is. Tall, big tits, athletic. Dressed in some sort of get-up -- maybe she was coming from volleyball practice or something? She sat down next to me and started playing with my dick. She pulled it out and sucked me off. Then she took off her shorts and sat down on it. It was a bumpy ride so I really didn't have to do that much thrusting. I played with her tits for a while and then we both came."

"And no one said anything?"

"We got a couple of looks, but... not really."

"And you... never spoke to her?"

"Nope." He shrugged. "I hope I see her again." He got up. "Anyway, I'm going to go jerk off."

"You know... you don't have to go upstairs to do that."

"You mean you want me to jerk off in front of you?"

"That's what the doctor suggested. I mean, not that, exactly, but she said you should masturbate whenever you need to. You can, um, feel free to jerk off whenever you want around the house. Whenever. Wherever." She paused. "And I can clean it up for you."

"Good to know." He took his semi-rigid cock out of his pants. Betsy gasped at its size, particularly its quickly thickening girth. He casually began to stroke himself. "I could use some lube, to be honest."

She couldn't tear her eyes from his penis. "I'll put some around the house."

"Great idea," he said. "What about right now, though?"

Betsy ran to the kitchen and got a bottle of canola oil.

"Will this do?"

"Sure," he said, putting out his hand. She poured a little into it. "Ahhh, much better. This isn't going to take long. I'm super horny."

"The hypersexuality," she said matter-of-factly.

"Yeah, I guess so. Fuck... this feels good." He was staring at Betsy's tits, even though they were covered by her boring, shapeless dress. There was something about them that had changed, though he couldn't put his finger on it. "By the way, Jenny and her sister, Sara, are coming over for a swim. Hope that's OK."

"Of course it is. Are you... going to fuck them?"

"Probably. They're super hot and slutty. Jenny's sister might be even hotter than she is, although I think Jenny's tits are bigger."

Betsy continued to stare at his cock, throbbing and super-swollen. "Um, also... you really seemed to enjoy suckling Mrs. Mulders at the mall."

"Yeah, that was fun. I was just glad to help her out." His hand began to speed up, and his other hand joined it. Betsy stared as he obscenely jacked himself off with both hands. "Shit, Mom, I'm going to cum soon."

"And you didn't mind her calling herself Mommy?"

"No, that was actually pretty hot."

"Would you... like to call me Mommy?"

"Sure, if you want."

"It would make me very happy." God, she wanted to touch herself so badly.

"SHIT, HERE IT CUMS, MOMMY!" His hips began to buck forward as rope after rope sprayed onto his delighted mother. She was soon covered. "Damn, that felt good. Sorry I came all over you. Though you don't seem to mind, huh?" Betsy, stunned, shook her head. "You'll clean this all up?"

"Of course," she mumbled, shaking with lust.

"Cool." He leaned in. "Mommy." He winked, massaging his cock, which was still hard. He kissed her on her cum-splattered cheek, wiped his cock on her dress, and headed upstairs. She made a note to herself to get lube. Lots of it. She sat back down on the couch, ignoring her cum-splattered face and dress, and, with her legs high in the air, she masturbated.

***

Before she finished, Betsy was frustratingly interrupted by the doorbell. She pulled her dress back down over her legs and went to answer it. Jenny and Sara stood there in what were basically pornographic schoolgirl outfits: tight t-shirts, that weren't designed to be cut-offs, but were so small that they were pushed out enough by the teens' huge breasts, exposing their slim midsections; flared skirts short enough to barely cover their crotches, and high heels. Each girl had her hair up in a ponytail. They could have been twins but for Jenny's slightly larger breasts and Sara's nerdy glasses and lighter brown hair. Sara was sucking on a lollipop and had a bag slung over her shoulder.

"Hey, Mrs. Pepper!" the girls said in unison.

"Hello girls," Betsy said, coldly.

"You remember Sara, right? She's my big sister."

"I do. Brian babysat for both of you, I believe."

"He sure did," Sara said. "Sort of weird, since he's barely older than we are, but we both loooooved being babysat by him."

"Yes, I remember."

"Brian invited us over for a swim," Jenny said. "OK if we come in and change?"

"Of course," Betsy said, allowing the girls to pass her by. "Why don't you go to the downstairs bathroom to change. I'm sure Brian will be down soon."

"Hey ladies!" Brian said, as he descended the stairs. He was wearing only a bathing suit, his muscular torso on display.

"Heeeey Brian!" the girls said, giggling.

"The girls were about to go change," Betsy said.

"Great, I'll help them out."

Betsy rolled her eyes as they girls ran off, giggled more about how much Brian was going to love their swimsuits.

The mother, too, headed upstairs to change. She had gone shopping the day before and had a surprise for Brian -- and his new bimbo girlfriends.

Once in her new outfit, covered only by a sheer, diaphanous robe, Betsy looked out of her bedroom window onto the backyard pool. Brian was frolicking with Jenny and Sara, who had changed into bikinis. Their busty teenage bodies were on full display, and Brian groped them seemingly at will. They took turns kissing Brian -- and also each other. Brian's swimsuit had been thrown onto the platform next to the pool, his huge, thick cock bobbing up and down in the water.

Betsy decided that it was time.

She walked downstairs and out onto the patio. Brian was leaning back on a ledge in the pool, arms draped over its edge, as Sara went to town on his cock, which stuck out of the water. Her head was bobbing up and down on its immense thickness, and at the same time he was making out with Jenny, groping her huge tits.

Betsy let the thin robe fall and let out an "ahem."

"Holy shit!" Jenny said, pulling her face away from Brian's. "Is that... your mom?"

Brian looked over and his eyes widened. "Jesus," he mumbled. "Mommy?"

Betsy Pepper stood on the patio, all five feet, two inches of her, in a micro sling bikini wildly ill-suited to her body -- her newly erotic body.

All of Betsy's time in the gym had paid off. Everything had tightened up. There was a hint of a six-pack and her legs in particular were thicker and more shapely, tapering down to her four-inch slingback heels. She had her light brown hair done and it fell across her beautiful face, slightly made up, and down to her shoulders in thick, wavy strands.

But all of that was overshadowed by what the absurdly revealing outfit showed off most: a stunningly enormous, shockingly round pair of breasts, perched high on her chest, held back only by the tiny cups of the sling bikini, just barely covering her nipples. The tits were so gigantic that the bikini slings pushed out from her shoulders on top and her pussy -- again, barely covered -- on the bottom, tenting inches off her body.

Betsy rocked her torso back and forth, which did two things: her gigantic tits swayed and wobbled under the sling bikini, and it allowed Brian a look at Betsy's huge, round, tight bubble butt cheeks, which the back of the bikini slings disappeared between. There was no other phrase to describe her new physique besides utterly pornographic. Both girls sat up, Sara's face smeared with Brian's precum, and gawked along with him.

Brian continued to stare, but took Jenny's head in his hands and slammed in down on his cock. She gagged immediately, but Brian didn't stop. He used her throat like a cocksleeve. His eyes boring a hole in his mother's wildly, epically voluptuous body, he thrust his thick penis in and out of the teenager's mouth, growling with lust.

"FUUUUCK!!!" he roared, quickly flooding Jenny's mouth, which was pressed down at the base of his penis. She withdrew, coughing, but didn't complain. Brian got up from the pool, not taking his eyes off of his mother, his muscular body dripping water along the deck, his cock still extremely erect, swaying back and forth and visibly throbbing. He walked up to her, towering over her even in her heels.

"Mom... um, Mommy," he said, closing in on her. "You look... incredible." His cock pressed into her belly, pulsing hot against her skin. "Jesus, your fucking body..." He stared at her colossal tits, then lifted his gaze and stared into her eyes.

"Thank you, baby. I wanted to surprise you with my new mega-busty Mommy-Slut body."

"How?... I don't understand."

"Does it matter?" she said, reaching up to kiss him gently on the lips. He pulled her into him and they began to make out. She could feel precum trickling down her abdomen. "Want to know Mommy-Slut's measurements?"

Brian gulped and nodded.

She drew it out, pointing delicately at the appropriate body parts, from her hips -- "38..." -- to her tiny waist -- "26..." -- to her enormous bust -- "36... J-cups, baby. Bigger than either of your stupid teen sluts."

Brian gulped again. "Jesus," he mumbled, staring at his mother's enormous bosom.

"Brian?" Jenny said. "Don't you want to come play with us?"

"Get lost," Brian said, not even looking back at them. "Turn around," he said to his mother. She slowly spun around, pushing out her breasts and butt for him. "Jesus, your tits are so huge I can see them from the back. And that ass..."

"Brian?" Sara called out.

"I said get the fuck out of here!" Brian shouted. The two girls climbed out of the pool in a huff, grabbed their clothes, and left -- though not before taking a last look at both Brian, wildly erect and shaking with lust, and his erotically proportioned mother.

"You know what I learned doing some googling, Brian?" Betsy said seductively. "Hypersexuality? It's genetic."

Brian gulped and nodded.

"I'm just as horny as you are. And hypersexuality affects both primary sexual characteristics, like your huge penis and my tight, wet pussy, and secondary ones like my gigantic tits and big, plush ass." She wiggled everything as a sort of proof. "Want to masturbate together?" Betsy cooed to her son.

"For a start," he said. "What I really want to do is fuck the living shit out of you."

"In due time," she said with a smile, swaying over to a lounge chair by the pool. She lay down, lifted her legs into the air, and moved the tiny bottom patch of her bikini, revealing a neatly trimmed, dripping wet bush. "Come jerk off to Mommy's super-busty body." She began to massage her clit with one hand and one of her giant tits with the other.

Brian's breathing quickened as he approached his mother.

"Not too close, sweetie," she said. He stopped where he was, a few feet from the lounger. She was enjoying the control she had over him. "Show Mommy how much you can cum for her."

He wrapped both hands around his cock, which was already slick with plenty of precum. He began slowly, eyeballing his mother's body, then quickened his pace as he matched her rhythm.

"Mommy's going to have an orgasm soon, sweetie. Will you cum with me?"

"Fuck yeah, Mommy. I'm going to cum so much for you."

"Good boy. Get all that nasty cum out of your big balls. Show Mommy how much you love her."

"Fuuuuck, Mommy... It's getting close..."

"So you like Mommy's new body? It's all for you, sweetie. Mommy's body is yours to play with... eventually."

"FUUUUUCCCKKK!! MOMMMMMYYYY!!" He was so close.

"UUUHHHHHH!! MOMMY'S CUMMING NOW, BABY! CUM WITH MOMMY!"

Brian's head lolled back and he let out a roar. Cum spurted out of his huge, pulsing cock, rope after rope arcing through the air and splattering on his mother's body, the lounger, and the stone tiles in front of him. The mother and son were soon panting together as they came down from their orgasms. But Brian's cock was still erect.

"Great job, sweetheart," Betsy said, licking a dollop of cum from one of her enormous teats. "Mommy is going to go take a shower and then change into something a little less comfortable."

She giggled. For the first time in years, she giggled.

Brian wanted to jump on her and fuck her right there.

"But you have to be patient, sweetie," she said, sensing his desires. "Don't be a naughty boy."

"I won't... Mommy."

"Good boy. I'll meet you in my bedroom."

She got up and swished her way to the sliding door, then turned around and blew him a kiss before disappearing into the house. Still as erect as he'd ever been, he followed her inside, his huge cock swaying back and forth.

Betsy walked upstairs, feeling her son's eyes on her cum-covered, barely clad, wildly voluptuous form. Something was different, and it wasn't just her body. Something had broken inside her -- and perhaps inside her son. She loved the feeling of control, of sexual expression. She wanted to tease her son, tease him until he absolutely had to fuck her into oblivion.

She pulled off her bikini and got under the shower, rinsing her son's cum from her body. As she enjoyed the warm embrace of the water, running her hands over her over-developed body, she heard a noise. Out of the side of her eye, she saw Brian in the doorway, again masturbating with both hands. She decided to give him a show, squeezing her massive tits, spreading her huge ass cheeks to show him her little butthole, bending forward as she soaped up her ass and thick, shapely legs.

"Don't cum again until I tell you, Brian," she said over her shoulder, smiling to herself.

"Dammit," he muttered. "Don't take too long."

"You're being naughty. Go to the living room and sit there. I'll be down in a minute. Do not jerk off. You won't get your surprise."

"Yes, Mommy." He sulked off.

Betsy slowly toweled herself dry, then changed, modeling a new outfit in the mirror. This was the one, she thought: the outfit to drive her son crazy. She put her heels back on, pinned her hair up, lotioned her legs and arms, and put on a deep shade of lipstick. She smiled at herself in the mirror, turned, and jiggled down the stairs. Brian was sprawled out naked on the couch, his cock temporarily flaccid. Now it was his turn to gasp.

His mother was wearing, by far, the most erotic outfit he had ever seen. It would have been erotic on any body -- on hers, it was outrageously pornographic.

Working his way up from her high heeled feet, he look in her legs, shiny with lotion, slim at the bottom and thick at the thighs. She didn't wear panties, her trimmed pussy on display. She was, though, wearing garters that attached to decorative, black leg harnesses. Above that, her toned stomach. His eyes kept wandering up until they got to the main event: an enormous, frilly black-and-red bra, overflowing with breast meat. It projected so far forward that the straps dug into her delicate shoulders and strained forward, looking like they might snap at any second.

She wiggled her torso, her massive tits swaying back and forth.

"What do you think, baby?"

Without having touched himself, Brian was, again, rock hard. His cock bobbed up and down over his muscular stomach and chest.

"Holy shit," he said.

"Does that mean you like it? Want to see it from the back?" She turned, slowly, raising her arms above her head and shaking her huge ass for him. "Can you see my tits from behind like before?"

Sure enough, her breasts were so gigantic and round that they stuck out on either side of her otherwise slender torso.

"Yes," he mumbled. "They're so huge. Mom, I --"

"Mommy," she said sternly.

"Sorry. Mommy... you're incredible. Please stop teasing me. I need you so badly."

"I know, baby. I know you do. Now stand up for Mommy."

He did, his magnificent cock sticking out in front of him. He really was gorgeous, she thought. And, she had to admit, she was drawn to him sexually just as much as any of those random women were. It was only then that she noticed that Brian, just barely, almost imperceptibly, was pumping his hips forward and back -- fucking the air, in essence. God, she thought, he really was just as horny as she was.

She walked up to him until her gigantic, bra-clad tits were caressing his muscular chest. She leaned up and began to kiss him. His hands wrapped around her slim waist and began to migrate upward.

"No touching Mommy's breasts or ass yet, baby. My waist is OK."

"Sorry, Mommy." She was loving the level of control she had over him. Despite his many, many orgasms over the last few weeks --most recently just five or so minutes before, in Jenny's teenage mouth he was a caged beast desperate for sexual contact. He would do anything she wanted.

For now, that meant kissing. They started slowly, but were soon making out like two teenagers on a first date. He took the back of her head in one hand and pulled her face into his.

"I love you so much," he whispered, kissing her neck, her ear, her wet mouth.

"I know you do, baby. Now get on your knees and put those lips on Mommy's pussy."

He immediately dropped to his knees and began to kiss and gently lick her vagina. She pulled his face into her, encouraging him to go deeper. She began to moan and felt an orgasm welling up inside her.

"That's wonderful, sweetie. Keep licking Mommy. Focus on my clit now. Yes! Just like that. Circle it with your tongue. Oh god, baby, you're making Mommy feel so good!" She cupped and played with her enormous tits, marveling at just how swollen they were. "You're going to give Mommy an orgasm! Keep going, baby! Here it comes! FUUUUUCKKK!!! CUMMMIINNNGG!!!"

She legs almost gave out as she felt herself squirt all over his face. She had never squirted before. He pulled his face away; it was covered in her goo.

"Did I do a good job, Mommy?"

"Very good, baby. Now lick Mommy's asshole."

She turned and bent over, sticking out her huge butt cheeks and pulling them apart to give him easier access. He didn't hesitate, tonguing her tiny asshole. She reached down to masturbate and it didn't take long for her to come to another orgasm, again squirting all over the floor.

She turned around and Brian rose to meet her.

"Please Mommy... I want to play with your body. I've been a good boy. Please let me, I'm begging you."

His entire demeanor was different. She had won.

"You have been a good boy," she said, licking her own juices off his face. "And you're a very handsome and sexy young man, with a very large, thick penis. It's time to play with Mommy."

She reached behind her and began to unhook the massive bra barely containing her breasts. "Are you ready to see Mommy's giant tits up close?"

"Yes, Mommy," Brian said, panting, his enormous prick throbbing as he now fully thrust it into the air in front of him. He was increasingly like a savage beast and she giggled at how much control of himself he had lost.

"Ta-da!" She pulled off the bra and her giant, round tits were on full display, her nipples erect and taut. "Go ahead, baby," she cooed. Brian immediately been to grope and squeeze them, both of them groaning with pleasure.

"Jesus, they are huge. I love them so much, Mommy." She lifted one up and suckled her own nipple, eliciting more groans from him, then offered it to her son, who didn't need any further encouragement. He bent down and licked and sucked on it as if his life depended on it. She took the opportunity to gently tease his cock, which was as hard as she'd seen it and dripping with precum. She raked her fingernails across its length. More groans came from Brian.

"OK, baby, it's time for us to fuck." She took a step back and lowered herself onto the shaggy carpet. She lifted her shapely legs into the air and pulled them back, opening herself up for her son. "Come fuck Mommy, sweetie. Go slow. Your penis is very, very thick and Mommy's pussy is quite little."

Brian wasted no time. He propped himself up, hovering over her. He couldn't help but stare directly at her massive breasts; she arched her back to more easily thrust them up and toward them. They wobbled, taut and swollen, just inches from his face.

She smiled up at him. "You can stare at Mommy's huge tits while you fuck her. I know how much you love my mega-busty body."

He did just that, using one hand to guide himself inside of her. She immediately let out an intense moan, feeling him fill her up inch by inch.

"Jesus you're big! So fucking thick! Keep going, baby. Fill Mommy all the way up."

Soon he was completely embedded in her. They stayed like that for a minute, soaking in the situation. He slowly pulled almost all the way out, then thrust back into her.

"FUUUCK!" she screamed. "That feels so good, baby. Mommy's going to have another orgasm really soon. I guess we both really are hypersexual, huh?" She cupped her massive, round tits for him, encouraging him to fuck her harder. He did, thrusting and grunting like an animal. "More, baby! Fuck Mommy harder! SHIIIIIT! HERE IT COMES, BABY! MOMMMYYYY'SSS CUUUMMMMIINNGGG!!"

Her entire body began to shake and quiver as she came again, this time on his cock. She felt fluid dripping from her cunt as it spasmed around his immense thickness. They were both dripping with sweat now, heat emanating from their rutting bodies.

He buried his head in the crook of her neck and started muttering, "I love you I love you I love you..." She put her hand on the back of his head and shushed him gently. "Good boy, sweetie. You're doing such a good job, fucking your huge-titted little Mommy. Time to cum inside me."

"ARRRGGHHH!" he roared, as he thrust even harder into her, spraying an immense amount of cum into her tight pussy. Once finished he collapsed on top of her, her giant tits crushed against his chest.

"Good boy," she whispered in his ear. "You fucked Mommy so good. No more sluts, right baby? Just Mommy. That's all you need, right? Mommy's ultra-busty body. Because you love me, don't you? You love Mommy-Slut and her giant tits."

"Just Mommy," he repeated, kissing her on her face, her neck, her breasts. "No more sluts. Just Mommy's ultra-busty body. I love you so much. Love you..."

He trailed off as he began to slowly piston his cock inside her. He was still hard. There was so much more fucking to do, she thought.

They continued in the shower, Brian pinning her body to the tile wall, her legs and arms wrapped around his muscular form, as he pounded her to another orgasm. They dried each other off, intuitively focusing on each other's swollen sex organs, which only got them horny again. He bent her over the sink and fucked her again from behind, her huge ass rippling as he emptied another load into her pussy.

"Fuck my swollen-titted body, sweetie! Drill your fucktoy Mommy, baby!"

Exhausted, they took a nap. Brian awoke to his mother's massive tits shaking wildly as she bounced up and down on his erection. She apologized for waking him as she rode through yet another orgasm. After he, too, came, they drifted back to sleep. This time he woke her up, entering her from behind as they spooned, reaching around to grope her enormous breasts and tweak her throbbing, erect nipples.

As she had promised, she put jars of lube around the house and he continued to masturbate whenever he felt like it. If she was around, she would model her body for him, striking erotic poses and begging him to cum for his Mommy. It never took long. And he never seemed to run out of semen.

During breakfast the next morning, Betsy crouched in front of Brian after he finished his eggs, sucking him off -- and, in the process, discovering that she lacked a gag reflex. (Another "symptom" of hypersexuality, she thought to herself as the cock entered her throat.) She took all of the huge organ as he reached down to play with her immense bosom. He eventually emptied his balls into her. That was her breakfast.

Later, after Betsy came down the stairs wearing only a tiny t-shirt -- which her huge tits pushed out so far from her body that it might as well have been a tube top -- Brian ripped off his clothes and took her right there at the bottom of the stairs. He pressed her head into the carpet as he took her from behind.

"Please, baby... UH! FUCK! Flip me over so I can see your beautiful face."

Her enormous tits swayed as he did. He grabbed her throat and began to gently squeeze.

"Yes! Choke me, baby! Choke your fucktoy Mommy while you ream her senseless!"

He did, and they orgasmed together.

Day after day played out like this. They fucked everywhere in the house, including in and around the pool, where she screamed for the entire neighborhood to hear. They began to fuck in public. He would pull up her skirt on the bus and take her from behind.

One afternoon, they returned to Dr. Powers office to give her an update. Both Dr. Powers and Cindy the receptionist were startled by Betsy's new body, which she showed off in a tight yoga outfit that hugged her wild curves. The doctor and Cindy trailed her into an exam room and listened as she and Brian recounted how their sex lives were going. Both began to masturbate, almost on autopilot, and soon all four were naked. A three-hour foursome commenced. Brian fucked each of them in every possible configuration, orgasms rolling into one other. He fucked the doctor from behind, her huge tits swaying back and forth; then continued on to Cindy's tight little body, which she bounced up and down on his cock as he sat in the doctor's office chair. Finally, Dr. Powers and the receptionist played with each other's swollen bodies as they watched Brian drill his mother on the exam table.

Eventually, Brian lined them up in order of breast size: Cindy and her DDs, Dr. Powers and her GGs, and, finally, his very own mother and her J-cups. They sat on their knees in front of him, cupping their big-to-huge-to-gigantic tits, begging him to glaze them. He did, one by one, carefully saving enough cum to cover each of their faces.

But each day the mother and son would return home and cuddle, Brian always gravitating toward his Mommy's gigantic bosom, as she stroked his hair and whispered into his ear how much she loved him.

Eventually he would fuck her again. And again. And again.

He couldn't stop. He couldn't get enough of his mega-busty fucktoy Mommy.

He was all hers.
