A quick note: My stories aren't for everyone. If you don't like very petite women with really huge breasts, 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. (One additional note for this chapter: It contains behavior that in real life would be reprehensible. I hope everyone understands the difference between real life and fantasy.) (All characters are over 18 years old.)

DAY FOUR: TEASING BIMBO DAY

The next morning, after a deep sleep undoubtedly aided by a day of epic sex with his wildly busty mother, aunt and cousin, Brian woke up curled between his mother and Jenny, whom he was spooning, his morning erection pressed against her ample buttocks.

Brian slid his cock into his cousin, who, still half asleep, let out a deep, satisfied moan. He reached around and began to grope her gigantic breasts, tweaking her nipples and squeezing the huge sacks of tit-flesh. He began kissing her on the neck as he slowly pumped into her, until she turned her head and they began to make out.

The movement of the two awoke his mother, who pressed her giant tits into her son's back and whispered into his ear, "Fuck your super-busty cousin, sweetheart. Cum inside her again." She then turned toward her sister and, now both awake, they began to make love, kissing and playing with each other pussies.

Brian lowered his hand and began to massage his cousin's clit, quickly bringing her to the brink of orgasm, as her entire body shook and shuddered. "UHHHHHH! BRIAN! I'M GONNA CUM ON YOUR HUGE PENIS!! FUUUUUUUUCK!!"

He felt her pussy contract around his cock as the orgasm reached a crescendo, which led, in turn, to the churning of cum in his balls. He grunted repeatedly as he shot his first load of the day into his ultra-buxom cousin, squeezing her massive tits as he ejaculated. Soon, his mother and aunt orgasmed as well, screams echoing through the house.

The day had just begun.

After recovering, the quartet put on some clothes -- all three women wore tiny t-shirts that their huge breasts pushed out, their nipples clearly visible, and panties -- and went downstairs for breakfast.

As they ate their eggs and toast, Brian's mother broke the silence: "So, listen, I know we all had an amazing time yesterday, but Brian and I only have a few days left and there are some more... things I want us to do."

"We totally understand, sis," Becky said. "We'll give you guys some space."

"But... Mommy..." Jenny muttered.

"It's okay, Jenny, we'll be back. There's some stuff we wanted to do on our road trip anyway. I promise we'll come back."

Jenny looked crestfallen. "Okay." She paused. "Can Brian fuck me one more time?"

Becky laughed. "Kiddo, I think you're addicted to someone's cock. And I don't blame you."

"No! I really love him!" She looked over at Brian with a bashful expression. "Though I do also love his cock."

"Jenny," Brian's mother said, "I promise this won't be the last you'll see of Brian or his cock."

"Okay, okay."

"Alright," Aunt Becky said, getting up, her huge chest jiggling under her shirt as she did. "Jenny, let's go get cleaned up and dressed."

A half-hour later, the dishes were done and Brian was saying goodbye to his aunt and cousin, fucking both of them by the front door. He had intended it to be a quick kiss and hug, but Jenny wouldn't break their embrace and soon she was pulling down both of their shorts and guiding his cock inside her. Her mother rolled her eyes, but soon she, too, was fucking her nephew. Brian's mother just stood by, shaking her head, as each woman orgasmed in turn. Brian staved off his ejaculation, having the feeling that he should save some energy for the day.

After another set of kisses and hugs later and the mother and daughter loaded up their car and drove away.

"I know you're going to miss them, baby," Brian's mother said, sidling up to him, her giant breasts pressed against his arm, her hand running along his erect penis. "But trust me: today is going to be a lot of fun. And remember, I am totally into... the plan. If it makes you uncomfortable, just say the word. But given how assertive you've become, I don't think it will. And although I know you know this: in regular life, listen to a woman's words. Today, I want you to ignore that. Follow what I do, not what I say." He nodded. "Okay! Sooooo... why don't you hang out here in the living room and I'll go get changed?"

Brian plopped down on the sofa, watching his tiny, voluptuous mother make her way up the stairs, her huge tits bouncing under her t-shirt. He couldn't wait to see what she would wear next.

A few minutes later, he was not disappointed. His mother jiggled her way down the stairs in a tiny black micro-skirt that hugged her bulbous ass and barely covered her pussy and a skin-tight white button-down top out of which spilled an enormous amount of cleavage. On her feet, she wore red, five-inch heels, pushing out her tits and butt and making her sway with each step. Brian immediately became erect; he had never wanted to ravage his mother more.

But then she did something odd. Instead of coming over to him, she went to the kitchen and bent over to rummage through a drawer, exposing her little pair of panties. He walked over to her, his short-covered cock swaying inches in front of him, and lightly brushed up against her.

She gasped and twirled around. "Oh goodness!" she squealed. "You scared me, Brian. I was just going to get started on lunch. Would you like something."

"Yeah, Mommy... you."

Again, she gasped. "What do you mean, darling?" Her massive tits swayed in front of him, threatening to burst from the top. She seemed to be pushing them out toward him even more than usual. He could now see that under the top she wore a red push-up bra, its straps pulled away from her neckline by the sheer force of her bust. He also noticed that she was made up more than she had ever been, with bright-red lipstick, long lashes and rouge. She looked, Brian thought, like a slut. An insanely gorgeous, wildly voluptuous and extremely petite one, but one nonetheless.

"I mean I want to fuck you. Hard." He pulled her body into his.

"What?! No, Brian, I'm your Mommy! You shouldn't want to fuck your own mother. That's sick." She made a feeble attempt to push him away, her little hands pressing on his immense chest.

He now knew what she meant about not listening to her words but rather her actions. Normally, of course, he'd respect the direct meaning of what she was saying, but this was what she was preparing him for.

"Brian, please let go of me!" She wriggled in his grasp, but not very hard, making her tits jiggle in her ultra-tight top. "I'm your Mommy! You can't possibly want to... make love to your Mommy?" He noticed that despite her protests, she was pressing her tits against him and her skirt-covered groin, aligned with his because of her heels, against his rock-hard cock. "Oh, my goodness! Is that... your penis, Brian? Are you... erect?"

"Very. Because of your ridiculously voluptuous body and this incredibly erotic outfit you're wearing."

"I'm just wearing... clothes."

"You look like--" He stopped short.

"What where you going to say, Brian?"

"You look like a whore, Mommy! Your tits are bursting out of that top. That skirt barely covers your pussy."

"Brian! How could you use that language with your own mother!"

He released her. Her chest was heaving, a light sheen of sweat forming on her skin.

"Oh c'mon, Mommy. You're dressed like that to turn me on! To get me hard!"

"I don't know what you're talking about," the mother said, backing up until she was up against the wall.

"I'm talking about this," Brian said, pulling down his shorts and allowing his huge cock to spring upward, directed right at his mother's gorgeous face.

"Oh my god, Brian! Put your penis away, right now."

"I'm sorry Mommy, I can't do that," he said, kicking his shorts away and pulling off his t-shirt. "I'm going to have to fuck you. And it's your fault."

"Brian! Stop talking like that! You can't possibly want to... fuck your own mother! It's incest. It's a sin and disgusting."

Brian grabbed her tits and began to molest them through her top, pushing even more breast-flesh up, almost to her chin. "And these tits! They're gigantic, Mommy! You really expect me to not way to fuck you when you flaunt them like this?"

"Brian, stop playing with Mommy's breasts!" the mother said, though didn't make any attempt to actually remove her son's hands from her massive chest.

"Listen, you stupid fuck-slut," Brian said, wondering if his language was going too far, "I'm going to do whatever I want with your giant tits. You're a stupid bimbo who's only good for one thing."

"Baby, please! I'm not a bimbo! I'm... oh god..." She trailed off as Brian began to rub her nipples through her top.

"You see! You're getting turned on just having your sensitive nipples played with through your skimpy little top."

She was breathing more and more heavily. "No, baby, I'm not turned on... Oh goodness... Mommy isn't a... a fuck-slut!"

Brian took one hand and thrust it down her skirt, under her panties.

"You're sopping wet! You can't hide it from me, Bimbo-Mommy."

"Please don't call me that, baby. I love you so much, but... I'm not a Bimbo-Mommy."

"Sure you are," Brian said, lowering her panties with one hand while he continued to grope a giant tit with the other. You're my little sex-toy. Only good for fucking."

"Uhhhh... Brian, no...." Yet despite her protestations, she began slowly thrusting her groin against him, like an animal in heat. Because of the height of her heels, she was bumping up against his rock-hard prick.

"I think this time we get rid of this ridiculous top," Brian said, as he took hold of each side of her white button-down top.

"Brian, no!"

But he ignored her, ripping the shirt apart, buttons flying everywhere, revealing a massive pink bra that was clearly too small for her enormous tits, as well as her toned stomach.

"Oh my god!" Her hands flew up in a vain attempt to try and cover her enormous rack, but Brian quickly pinned them to the wall above her head.

"Uh-uh-uh, Mommy. Time to see these giant melons. Take off your bra or I'll put you over my knee and spank you."

"Brian, you wouldn't!"

"Try me, Bimbo-Mommy."

"Oh god, I can't believe I'm doing this," she said, her hands shaking as she struggled with the front clasp on her bra. She finally got it undone and her enormous tits burst forth. Brian immediately began to molest them, twiddling and flicking her hard, little nipples, reveling in their firm sponginess.

"God, what a pair of tits. Stupid slut mommies like you should have to walk around topless so your sons can enjoy them anytime they want."

"Oh god, Brian... You're being so cruel, but..." She trailed off as her eyelids fluttered and she continued to hump his erection.

"But what, Bimbo-Mommy? It feels good? Just wait til I start fucking you with this huge cock."

"Oh, baby, no," she pleaded, even as she reached down and began to stroke his cock. "God, you're so big. It'll never fit into my little vagina."

"Oh, I disagree, fuck-slut. Here, I'll show you."

With that, he took her by the arm and threw her down on the carpeted floor, her massive tits flopping around as she squealed in surprise. He positioned himself in front of her, stroking his huge erection with both hands.

"Cock 'em, up, Bimbo-Mommy."

"No, baby, please don't fuck your mother."

"Do it. Put those legs in the air. Easier access to your wet pussy."

"Oh goodness," she said, biting her lip as she raised her legs up above her head. "Please don't rape me, sweetheart! Please don't put your huge penis inside of my little vagina!"

"Sorry, Bimbo-Mommy. Those gigantic tits and your adorable little body are just too much. Time for a really hard fucking."

He flipped up her skirt and put his cock at the glistening entrance to her pussy and began to rub it up and down her labia. "Baby, it's not too late! Don't rape Mommy! Please, I'm don't fuck your own mother!" Yet even as she spoke those words, she was bucking her hips up and down, encouraging him.

Brian smiled and, pushing his mother's legs even farther back, he slammed his cock into her.

"UUUHHHHH! Brian! Stop fucking Mommy!"

He responded by doubling down, thrusting his thick, turgid cock inside of her, watching her massive tits sway up and down with his rhythm.

"Say 'I'm a stupid, giant-titted fuck-slut who deserves to be raped by her own son' and I'll consider it."

"Oh god, Brian, no."

"Say it, Bimbo-Mommy."

"I'm... I'm a stupid, giant-titted fuck-slut who deserves to be raped by her own son. Now please stop fucking Mommy!"

"Sorry, not gonna happen," Brian said with a smile as he continued to ram his mother's pussy. "And start calling me 'sir.'"

"Yes, sir," she said meekly. She began to groan and her entire body started to shiver.

"Oh god..."

"You're going to have an orgasm, aren't you? What a fuck-slut, cumming from your own son raping you."

She began to lose control. "No... oh god... I... Sir, please... Oh god, here it comes... AHHHHHHHHH!!!"

Her whole body began to spasm as she thrashed around wildly. Brian pinned her legs behind her, so her pussy was pointed almost directly upward, her giant tits mashed against her face. He pounded her cunt relentlessly, through her orgasm, not giving her even a second to recover.

"Sir -- UH! -- please stop -- UH! -- fucking Mommy!"

"Not a chance, Bimbo-Mommy. In fact--" Withdrawing his cock from her, he took her little body and twirled it around, mashing her face into the carpet, her gloriously round ass sticking up. "Gonna fuck you like this for a while." He guided his cock back inside her, then grabbed her arms and pulled them back. She was his plaything.

"Sir! Bimbo-Mommy is begging you to stop raping her! Please!"

He smiled at her reference to herself using his degrading language as he continued to pound away at her poor, little pussy, girl-juice dripping from it onto the carpet.

"I may never stop fucking you, you stupid bimbo."

He pulled her body up, so she was erect, her legs wrapped behind him, and grabbed her massive tits from behind as he rammed into her.

"Tell me what a fuck-slut you are, you stupid cunt," Brian said, getting bolder with his degrading language.

"UH! UH! UH! Yes! Yes! Bimbo-Mommy is a stupid slut who needs to be fucked every day, sir! Please call Bimbo-Mommy bad names! Please fuck Bimbo-Mommy til she passes out!"

He had broken her. (Or the character she was playing, anyway.)

Without stopping, he got up, taking her little body with him, their bodies now dripping with sweat. He brought her over to the dining room table and plopped her down. Letting his cock slide out of her vagina, he placed her on her back, her head hanging upside-down off the edge of the table, and slammed his cock into her mouth. He grabbed hold of her enormous tits and began to face-fuck her, knowing she could take all of his cock.

"GLUUUCK, GLUUUUCK, GLUUUUCK" came the obscene sounds of his little Mommy taking his cock deep into her mouth and throat, a ring of foam forming around her mouth. Her pinched her nipples and deep groans emitted from her. He reached down and began to rub her clitoris, quickly bringing her to another orgasm, even as she continued to deep throat his cock.

He quickly felt his orgasm building and, grunting like an animal, he ejaculated into her mouth. He gave her a moment to catch her breath, used her top, which he grabbed from the floor, to clean up her mouth, then carried her to the couch. He placed her on his lap.

"You told me the other day that you can orgasm just from sucking on your own nipples."

"Yes, sir."

"Do it. Show me, Bimbo-Mommy."

"Yes, sir."

She lifted a giant breast to her mouth and began to suckle her tiny, puckered nipple. Her eyes fluttered and closed and she began to moan. He began to tweak the other nipple, accelerating the process. It was only another minute or two that -- without touching her clit or pussy -- she was overtaken by yet another orgasm. Her body spasmed and bucked on his lap; so much so that he had to grab her huge tits so she didn't fall off his lap.

As soon as her orgasm had subsided, he threw her on the couch and began to fuck her again.

For the next four hours, he fucked her repeatedly, as she alternately begged him to stop and encouraged him to continue, even as he continued to call her degrading names. After a while, she was orgasming every few minutes, one rolling into the next.

At one point, he pressed her body against the large windows facing the street, her tits pushed up against the glass. "Sir, no! Anyone can see us!"

"Shut up, slut," he said as he entered her from behind, lifting her off the ground by the waist to do so. He again began slamming into her. She groaned and turned her head so they could make out.

A trio of middle-aged women walked by in athleisure wear. They saw what was happening and gasped, covering their mouths in shock. Brian's mother gasped. "They can see us, sir!" But the duo was too far gone to care. He pounded her pussy and she orgasmed as her neighbors watched in a combination of horror and fascination.

Next, he told her to kneel in front of him.

"Cup those gigantic tits, Bimbo-Mommy. Present them to me for inspection."

"Yes, sir."

She cradled her massive breasts and pushed them up toward him.

"Are they to your liking, sir?"

"How big are they, fuck-slut?"

"They are 34HH, sir."

"And who owns them?"

"You do, sir. You own my entire, busty body."

"Very good, Bimbo-Mommy." He grabbed his huge cock with both hands and began to masturbate. "I'm going to paint you with my cum now."

"Yes, sir. Please mark your territory," she said, looking up at him pleadingly. "Please glaze my slutty face and grotesquely giant tits."

He pumped his cock for a couple of minutes as she whispered encouragements -- "I love your huge cock, sir," "look at how huge my melons are, all for you," "please spurt your cum all over me" -- and, with a roar, did just that, rope after rope crisscrossing her face and tits.

Finally, they both collapsed on the floor. She looked like she had been gang-banged, makeup smeared across her cum-coated face, skirt in tatters, her epically curvy almost limp. She rolled on top of him, kissed him deeply, and whispered into his ear, "Thank you, baby. Thank you so much. You're incredible."

"So are you." He paused. "I was worried I went too far."

"No, sweetie. That was exactly what I wanted. I love you so much. And I'm glad you enjoyed it too. It's part of your birthday present, after all," she said, smiling weakly.

They slowly made their way upstairs, washed off, and collapsed on the bed. They had missed lunch and dinner but were too spent to move. "I love you, Brian," she muttered.

"I love you too, Mommy," he said, as he drifted off to sleep.
