A quick note: My stories aren't for everyone. If you don't like very petite women with really huge breasts, lactation, mother-son incest (or the use of the word "mommy" in a sexual context), 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, though, please rate and leave a comment! Thanks.

DAY FIVE: MILK DAY

After the intense roleplay of the previous day, Brian and his Mommy were curled up in bed, recovering. As the sleepy mother woke up, she turned toward her son.

"Hi," she said with that innocent smile of hers. She snuggled toward him, squashing her giant tits into his naked chest.

"Hi," Brian responded, running his finger along her cute bangs with one hand, while cupping her perfect, round ass-cheeks and pulling her in even more with the other. The two began to kiss gently, almost hesitantly. Brian's mother could feel his erection pressing against her tummy and reached down to lightly stroke it.

"Yesterday was... pretty wild, huh?" she said.

"It was. But fun."

"I had such a great time. And I'm not sure I've ever had orgasms that intense. By the end of the day, I couldn't tell when one stopped and the next began. You were incredible."

"I love you so much, Mommy," Brian said, moving his hands from her butt to her HH-cup rack, gently groping and squeezing her enormous guns. He noted that they felt even bigger than they normally did, swollen and taut.

"I love you too, baby."

He began to squeeze her giant rack more vigorously. Suddenly, she bolted up and out of bed, her voluptuous body jiggling obscenely. "Oh! Um... I'll be right back."

She ran into the bathroom, a confused Brian still in bed with a rock-hard erection.

She called from the bathroom: "I've got an, uh, unexpected surprise for you!"

What a week, Brian thought. What could possibly top what the incredible experiences she had shared with him over the past few days?

She emerged from the bathroom with a towel wrapped around her adorable, tiny body. She undid the towel and let it drop to the floor. Brian was still confused -- until she reached up, grabbed her huge breasts... and squeezed. To his utter shock, streams of milk shot out from her little nipples.

"Ta da!"

"Mommy! What the... what's going on?!"

"So, do my breasts look extra big?"

"Actually, they do. And sort of... swollen."

She began to gently caress her volleyball-sized tits. "Before I planned this week, I ordered some pills online. I didn't think they were working, but just now, when you started to squeeze them, something felt different. Turns out, the pills worked! I'm lactating!"

"Holy shit, Mommy, that's amazing," Brian said, sitting up and moving to the edge of the bed. "Come over here."

The mother squealed with delight and stood in front of her son, cupping her massive tits right in front of his face. She lifted one giant boob to her mother and began to suckle from her own tiny, puckered nipple. "Mmmmm," she moaned, milk dripping from her mouth. "I think you're going to really enjoy this. Come, baby. Come suckle on Mommy's huge, milky teats."

Brian immediately leaned forward and attached to one of his mother's nipples -- which were apparently extra-sensitive, given the gasp of pleasure she emitted -- and was rewarded with a stream of warm, sweet milk. She moaned and pulled his head into her massive, swollen bosom, stroking the back of his head.

"Oh sweetie! That feels so good. Suckle harder. I love breastfeeding my little baby boy."

Brian continued to suck, gulping down the delicious milk, barely keeping up with the steady stream his mother was producing. He loved the feeling of being surrounded by her breast, as if it were his whole world.

"OK, baby, time to switch." Brian reluctantly pulled away from the massive breast, milk spraying onto his face. His mother giggled and wiped it away. "Sorry, baby -- I just can't believe how much milk I'm producing! It comes squirting out with the slightest touch. Do you like having such a milky Mommy?"

"I love it, Mommy. It's everything I could have dreamed of."

"Good boy. Come put your head on Mommy's lap and suckle from my other breast."

He did just that, staring up at his mother's massive tits, and, just barely visible beyond them, her glowing, adorable face. She was beaming at him, as happy as he'd ever seen her. He latched on to her other nipple and began to suck. This time, she gently massaged her breast, expelling even more milk into her son's mouth. Breakfast of champions, he thought.

"Oh goodness," his mother said, looking down at his throbbing cock. "Looks like someone besides me is really turned on by this. Do you want your Mommy to help you, baby?"

He could only nod his head as he suckled.

His mother squeezed the first tit, expelling some milk into her hand, which she then used to slicken her son's enormous erection, then began to stroke it gently up and down. Brian groaned into her tit.

"That's a good boy! Mommy loves your big penis," she said, as she began to stroke her son more quickly, using the twisting motion that she knew he loved. Brian again groaned into her enormous tit.

"Do you mind if Mommy masturbates, too, sweetie?" she innocently asked her suckling son.

He mumbled a muffled "no" and she snaked her free hand down and began to rub her clitoris. "Ohhhh... God, baby... It all feels so good... Mommy is going to cum soon! Here it comes baby! MOMMY IS CUMMING SO FAST!! UHHHHHH!"

As an orgasm washed over his mother -- Brian had trouble maintaining attachment to her nipple -- he saw something amazing from the corner of his eye: At the height of her climax, milk began to spurt from her open nipple. It seemed sexual arousal increased her production. As the orgasm hit its crescendo, milk spurted two or three feet in front of her and Brian had a difficult time keeping up with the breast he was attached to: he was gulping down milk as fast as he good. It was all too much.

"Oh god, sweetheart! Mommy is a milk machine for her little baby! Are you ready to cum for Mommy? Can you show Mommy how much you can cum?"

Brian's hips began to involuntarily buck up and down into his mother's hand, and soon, he, too, was approaching an orgasm. "AHHHH! MOMMY! I'M CUMMING!! IT'S GOING TO SPURT OUT OF ME!! FUUUUUUCK!!"

Ejaculate shot out of his cock, farther than he'd ever seen it -- it almost hit the ceiling. It rained down on them both. Covered in cum and milk, they sat there, panting.

"Wow," Brian's mother said, breaking the silence. "I... don't know what to say. That was amazing. I guess that's what happens when I orgasm."

"Um, I guess so," was all Brian could muster.

"Well, why don't we both take a shower and we can get on with the breast--" She smiled and giggled. "I mean, *rest* of our day."

As had become their daily ritual, they showered together, Brian soaping up his mother's petite, wildly curvy body. He spent some extra time on her enormous breasts, milk spraying out of her nipples as he groped them vigorously. Soon, she was stroking his cock and moments later it was inside her, as she bent over, milk mingling with shower water as it dripped from her massive teats. He grabbed her round bottom and pumped into her until they both orgasmed, their screams of pleasure echoing off the tiles.

After rinsing and drying off, they went to their respective bedrooms. Brian threw on a t-shirt and shorts and lay down on his bed, taking in what had already happened that day. It was almost too amazing to believe: His already epically sexy mother was now lactating from her swollen breasts. He never in a million years dreamed that he'd have to chance to suckle from her massive bosom, but he had -- and she was apparently so turned out by the process that she orgasmed from it.

Just thinking about it caused yet another erection, and Brian was tempted to masturbate, but knew it was best if he held off. He began to drift off when he heard his mother's voice calling from downstairs. "Brian! Sweetie! Come downstairs, honey!"

He couldn't do so fast enough, racing down the stairs. There, standing before him, was his mother, smiling that innocent, sweet smile of hers -- in stark contrast to the rest of her. She had put on her yoga outfit, which consisted of tight, rainbow-stripped leggings and an even tighter top. Her milk-filled breasts had clearly swollen beyond their "normal" HH-cup size: breast-meat was bulging wildly out not just from the deep cleavage on top, but from the sides. It seemed like it was about to burst.

"Hi sweetie! I thought I'd do some yoga. Do you want to watch?"

"Um, yeah, Mommy, that would be great. But..."

"But what, baby?" she said in her little-girl voice, twisting her body back and forth so her giant bosom swayed with it.

"Your top, Mommy."

"What about it?" she said, running her hands gently over her massive, jiggling bosom.

"I think it's too tight."

"Oh goodness," she said, looking down at her cleavage. I guess those pills really did make my tits swell up. It's really noticeable, huh?"

"Um, yeah. You look like you're about to explode out of it."

"Goodness. Well, this is the biggest top I have, so there's not much I can do about that."

She walked over to the yoga mat she had set up in the living room.

"Take a seat," she said to Brian with a wink. As he sat down, she immediately went into downward dog, her huge ass thrust up into the air, her gigantic, wobbling rack hanging down. "Mmmmm... it feels good to stretch." She moved into an upward dog, her tits jutting out, her nipples poking prominently through her top. She brought her legs up to her hands and stood up, stretching her hands above her head.

Brian was hypnotized by the movement of her body. It was only then that he noticed what should have been obvious: there were two large and growing wet spots on his mother's yoga top. All the movement and jostling had apparently triggered lactation.

"Um, Mommy..."

"Yes, sweetheart?" she said, swiveling the top of her body from side the side, and in the process shaking her giant tits back and forth.

"You... um, you're leaking."

The petite mother looked down. "Oh goodness! I guess I am. Hm. I'm not sure what to do. Brian, what do you think I should do?"

Whatever little game she was playing was turning Brian on to an epic degree. She was again playing dumb and he loved it.

"Maybe... maybe you should take off your top, Mommy."

"But then I'd be half-naked in front of my son." The lactation had increased to the point that droplets of milk were starting to form where her nipples jutted out.

He got up, walked over to her and stood behind her.

"What are you doing, sweetie?"

"Just trying to help." He took the bottom of her wildly over-stuffed yoga top and began to pull it up, struggling to get it past her enormous, volleyball-sized tits. He peered over her shoulder, admiring her immense, bulging cleavage.

"Baby! Please stop." As before, her actions belied her words: she made no effort to stop her son.

"Raise up your arms, Mommy." She did as he asked.

Eventually, he got the top up and over her massive rack, exposing her breasts -- milk now fully dripping from her nipples. He tossed the top aside.

"Your top was all wet, Mommy. You can't walk around like that."

"Goodness, I suppose not. But now I'm topless, Brian. And my breasts are dripping with milk."

"Yes, I see that," he said, as he pressed his erection between her large butt cheeks. He reached up and cupped the giant teats.

"Brian! I came down here to do yoga, not be groped by my own son."

"But Mommy, you can't possibly do yoga with your breasts so swollen with milk."

"Hm. I suppose not."

"I have an idea," Brian said, smiling deviously. And with that, he began to squeeze her enormous tits. Immediately, streams of milk burst forth from her nipples, arcing through the air a foot or two in front of her before splattering on the yoga mat.

"My goodness! Brian! You're milking Mommy!"

Brian squeezed harder and the milk kept coming, spraying a number of feet in front of her. His mother started to moan.

"Oh god, baby, you shouldn't be milking your own Mommy, but that feels so good..."

As he continued to milk one enormous breast, he reached down with his other hand, putting it under her yoga shorts and began rubbing his mother's clit. She groaned even louder and her legs began to give way. He held her up as her body began to shudder, milk still spraying from her tit. Brian felt her pussy contract around his huge cock.

"BRIAN! MOMMY IS GOING TO CUM! YOUR BUSTY, MILKY MOMMY IS GOING TO HAVE A REALLY BIG ORGASM!! UHHHHHHH!!!"

If not for her powerful son, she would have collapsed onto the yoga mat, but he held her upright as her wildly curvy body shook and quivered. As she came down from her orgasm, Brian twirled her around -- milk spraying their living room -- and mashed his mouth onto hers. He quickly pulled down his shorts, lifted his mother off the floor and plunged his cock into her.

"UHHHHH! FUUUUUCK!! FUCK MOMMY, SWEETHEART! FUCK ME WHILE YOU STARE AT MY HUGE, SWOLLEN, MILK-FILLED BREASTS!"

He did just that, watching her massive tits, dripping with milk, sway up and down as he slammed into her. Soon, he felt his cum boiling in his balls and knew his ejaculation was near. He latched on to one of his mother's breasts, sucking down her sweet, warm milk, just as his sperm flooded her little, spasming pussy. His orgasm seemed to go on forever, but finally it was done. He, though, wasn't.

He lowered her down onto the mat -- covered in a mix of milk, semen and girl-juice -- and placed her on all fours. Her huge tits hung down, dripping a steady stream of milk, and her bulbous ass faced upward. He grabbed her tiny waist and slowly entered her again as she moaned in pleasure. He began to slowly thrust in and out of her, watching her giant tits sway back and forth, her ass rippling with each thrust.

Soon she was cresting to another orgasm. "FUUUUUCK! CUMMING ON YOUR HUGE COCK! BABY, I LOVE YOU I LOVE YOU I LOVE YOU!!" Milk began to spray from her giant tits, soaking the yoga mat, which set Brian off. With a roar, he unloaded what seemed like a gallon of spunk inside of his little, busty mother's body. "CUMMING INSIDE YOU, MOMMY!! CUMMING IN YOUR LITTLE PUSSY!!"

They collapsed onto the mat, awash in a mix of milk, cum and female ejaculate.

His mother kissed him deeply on the lips, her milky breasts pressing against his broad chest. "Every time I think my orgasms can't get more intense... I love you so much, baby."

"I love you too, Mommy."

"I should probably cut back on these lactation pills, though," she said with a giggle, "or else we'll be drowning in milk." She lifted a tit to her son's face. "Do you want to suckle before we clean ourselves up?"

Brian didn't have to answer. He simply took a nipple in his mouth and began to suck, sweet, thick milk spurting into his mouth.

For the rest of the day, Brian and his mother fucked nearly constantly, taking breaks only for snacks and hydration. Showers, of course, were peppered with sex, Brian either pinning his petite mother against the wall and shoving his huge cock into her, or bending her over so her milk-filled tits pressed against the glass, ramming her from behind. She orgasmed multiple times, each time thick streams of milk bursting from her giant tits.

They fucked in both of their bedrooms, in the kitchen (both on the table and against the sink, when Brian saw her doing dishes from behind and realized her enormous breasts were clearly visible from the back and took her from behind), the dining room... The mother's orgasms followed one another, milk squirting each time; Brian came inside her multiple times, between her massive tits, in her mouth, on her face, between her round butt cheeks.

Needless to say, by the end of the day, the house was a complete mess, covered in every possible sexual fluid. As they cuddled naked on the living room couch, watching TV -- Brian suckling from one of his mother's still-swollen breasts -- she looked around and sighed.

"I guess I'll have to get this place deep-cleaned. And I'm definitely scaling back on those pills. I love squirting milk for you, but this is... too much. Luckily, tomorrow we'll be out of the house."

"We will?" Brian asked, interest piqued.

"Yup, tomorrow is..."

DAY SIX: FIELD TRIP DAY

After a full day of fucking his epically hot mother, Brian was worn out, to say the least. He crashed early and slept like a rock. Even so, an early wakeup left him groggy -- though not for long.

"Brian!" she called from downstairs. "C'mon down! Bring something you can swim in."

Swim? Brian thought. He looked out the window -- it was a beautiful day, warm and sunny. Dare he dream they were headed to the beach? The idea of his mother in a bathing suit...

Needless to say, he threw on a pair of swimming trunks and a T-shirt and headed downstairs. His mother was indeed waiting for him, and though she was wearing a relatively shapeless kaftan, nothing was truly shapeless on her. There was no question: A bathing suit was under that caftan and Brian desperately wanted to see it. She also had a large bag of beach equipment.

"Beach day! I hope you're up for some sun and swimming. And... other stuff," she said, beaming up at her son. Just then, the doorbell rang. "And there's our special guest!"

Could it be? Brian's dream life was only getting better and better. "I'll get it," he said and hurried over to the door. He opened it and there stood his cousin Jenny, without a doubt the most gorgeous, bustiest teen he'd ever seen. She, too, was wearing a loose beach coverup, but it was just barely diaphanous and Brian could tell she, too, was wearing a swimsuit under it.

"Hi," Jenny said bashfully, tucking a strand of her long, dark hair behind an ear. "It's... really good to see you again."

"Um, you too."

Jenny turned around and only then did Brian notice his aunt in a sporty little car at the curb.

"Have a great time, kiddo! You too, Brian!" she yelled. "Sorry I can't join you. I'm sure I'm missing a great time." Even from across the front lawn, Brian could see her wink before she peeled away.

"She's going to... visit a friend," Jenny said.

I bet she's got lots of friends, Brian thought lasciviously.

"Cool. Well, I'm really glad you're coming, Jenny."

"Me too." She paused, bashfully rotating her torso, making her massive breasts sway -- noticeable even under the caftan.

"Um, Mrs. Pepper?" Jenny asked.

"Yes, sweetheart."

"Would it be okay if I called you Mommy too, just for today?"

"Of course, Jenny. That's very sweet. Now both of you help me get this stuff into the car."

The teens did just that. Brian was about offer Jenny the front passenger seat when his mother said, "Brian, why don't you and Jenny sit in the back?"

Brian opened the back passenger door for Jenny, who smiled bashfully. He slinked in next to her. "Jenny, as Brian knows, I normally have a hard-and-fast seatbelt rule in the car, but just this once, we can skip it so you two can... move around." Brian saw the hint of a mischievous smile on his mother's face in the rearview mirror.

As his mother drove away, Brian slid his hand over Jenny's and smiled at her. He couldn't believe how stunning she was, her dark brown hair up in bun, her green eyes gleaming in the sun. He leaned in and they kissed, tenderly, kissing each other almost hesitantly, as if they were on a first date.

"You look... incredible, Jenny. You're really beautiful."
