Melissas Breakthrough Ch 07

"6 inches!?" Steve yelped, throwing his shaking hands up in front of him in a gesture of pleading desperation.

"What?" asked Melissa mildly, cocking her hip to the side as she stood there in front of him in all her nude glory. Having turned the thermostat up to 80, her naked skin was sweating gloriously, and her sweat was mixing with the oil that she had rubbed into herself an hour before. Steve knew this was "just Melissa," his nerdy, awkward, scientist stepmother, but if he was being honest, she looked like a Greek goddess right now.

"6 inches isn't even that small," Melissa continued, grinning down at her panicking stepson. She suddenly bent down towards him, shaking the vial of clear liquid over him. "I mean, I could shrink you down to 6 millimeters...or 6 micrometers, which is one millionth of a meter, or 6 picometers, which is one trillionth of a meter, or ten-to-the-negative-twel--"

"I get it, I get it!" exclaimed Steve quickly, nodding his head as he kept his hands up in the same pleading motion. "B-But Melissa please...please don't...don't make me, uh..."

"Smaller, Steve?" Melissa straightened back up and smirked down at him. "I'm sorry, but that was the deal. If you didn't wanna get even smaller than you are now, you should've tried harder to beat me!"

"I--I tried as hard as I could!" retorted Steve indignantly. "But it's a little hard when the pool table is...is shoulder-height!"

"Wellll, then maybe you didn't make such a good decision, entering into the deal in the first place, huh?" suggested Melissa mockingly. "Ohhhhh but that's right...you HAD to take the deal, because you just reeeeeallly wanna have sex with me, right?"

Steve tried to respond, but the words died in his throat as he bowed his head. He knew the point she was trying to make -- that he had invited all of this misfortune upon himself, only because he was helplessly lusting after his stepmother. Of course, she had done plenty to encourage this lust, not limited to striding around the house naked and striking sexy poses whenever she got the chance. If he had been able to control his desire for her, then he wouldn't be in conundrum right now. But now that he was, it was hard to acknowledge that he only had himself to blame.

He looked up at his stepmother, who was staring down at him, an expectant eyebrow raised. Steve blinked and swallowed a lump in his throat, as his cock, which had already been semi-erect for hours, became rock-hard all over again. She was just such a bombshell now...her long, strong legs, her huge, pillowy breasts, her powerful hips...and, of course, her gargantuan ass...she was so, so much bigger than him, so superior to him, that it was difficult to wrap his mind around the reality. And the thing was, the more Steve thought about it, and sank into that reality, the more aroused it made him. He had finally arrived at the realization that Melissa had probably been trying to encourage for days now -- that he WANTED to be submissive to her, that he ENJOYED it, and that he wanted it to KEEP GOING...that he wanted her to assert her dominance over him time and time again. There was no possible way for him to avoid admitting it now.

Staring up at her, he nodded meekly.

"Y-yes," he said quietly, "Yes I...I do."

"Mmmm, you DO reeeeally wanna have sex with me, don't you?" Melissa pressed on, clearly getting a kick out of all this. Steve nodded.

"Even if I make you smaller?"

He nodded again.

"ESPECIALLY if I make you smaller," Melissa laughed, nodding her head in tandem with Steve's. "Haha I knew it...you just wanna be under my huge, fat ass as I grind it on top of you, making you...uh, what's it called...uh, oh right! Making you CUM all over my big ass cheeks...yeahhh...that's what you want, isn't it?"

As she spoke, Melissa was turning around and shaking her huge, naked ass right in Steve's direction. Since she was standing on her tiptoes now, her ass was literally shaking directly into his face. Even though the erotic thrill of the image took Steve's breath away, he instinctively tried to back away from it. It was just so enormous, so huge...he thought that her ass alone probably weighed close to his entire bodyweight by now. But there was nowhere for him to go. Melissa had once again backed him into a wall with her ass, and was now shaking her massive, jiggling cheeks up against his face.

"Well what are you waiting for?" teased Melissa, putting her hands on her knees as she crouched her ass into his face. "Go on, Steve! Put your cock into my ass! Come on, do it! I'll let you do me in the ass, Steve, if you can reach, haha! Isn't that all the rage? Having sex in the ass these days? I hear that it's a big deal when a woman lets you do that. Well Steve, I'm letting you do it to me now! Wait, no...not even that -- I'm telling you to do it! I'm BEGGING you to do it, Steve!"

Melissa started moaning out in great exaggeration, as she grinded her huge ass into Steve's face. His cock was so hard now that it was throbbing painfully, but there was no way he could get it anywhere close to Melissa's ass.

"Mmmmmmmm come ON Steeeeeeve!" Melissa groaned sexily, "Please, PLEEEEEASE fuck me in my ass! Oh my GOD...I NEED it, Steve! You feel how big my ass is?? It neeeeds to be fucked. Please, Steve...PLEEEEASE fuck me in the ass!"

But try as he might, there was nothing Steve could do about his raging desire. His entire body was flushed crimson with desperation, and when Melissa finally stepped off him, giving him a respite, his body crumpled to the floor in an exhausted heap, totally defeated by her ass.

"Hahaha oh my god Steve!" Melissa laughed, turning back around. "That was just a little teasing! A little appetizer! Just LOOK at you -- you're a total wreck already! Yeeeeah, I'm not sure if you're gonna be able to handle me, especially not when I shrink you down to 6 picometers here in a minute."

Steve's eyes went wide and his head shot up, causing Melissa to laugh harder, jiggling all her sexy flesh as she gripped the sides of her hips, bending over slightly in her mirth, and causing her incredible tits to swing underneath her.

"Kidding, kidding!" she laughed, holding up the vial again. "So you're what, 4'9 right now? How about we start by shrinking you down to a niiiiice even 24 inches, huh?"

Steve blinked in silence, his eyes going back and forth between the vial of clear liquid and his stepmother's smiling face. He didn't know whether or not she meant to do it or not but he could see her sexy tongue issuing forth, just barely, between her lips, licking them hungrily. He felt completely trapped; he wasn't really in a position to refuse her, was he? And, in any case, he knew that Melissa was right -- he had no one to blame but himself. He was cornered by his own dirty desires.

Bowing his head slightly, Steve nodded. He heard Melissa exhale softly exhale in laughter above him, creating a little blast of air that ruffled his hair.

"Pssshhahaha come on Steve," she chuckled, wrapping her huge hand around his chin and diverting his head back up, so that he was looking straight up into her shining face. "Don't act like you're being led to the gallows!"

She glanced down pointedly at his groin, where his hard cock was conspicuously pressing into his oversized pajamas. Her smile widened across her face, and she raised her eyes slowly up his body, until she was staring at him straight in the face once more. Her eyes held his dominatingly, and for several seconds, she didn't say anything at all. Instead, she just kept staring at him, penetrating through to the core of his basest desires. Steve felt like she was stripping him naked with her stare, and he felt smaller than ever.

"Mmmhmm," she purred knowingly, "You can pretend to be as sad and dejected as you want, Steve...but your little penis can't lie, haha!"

Melissa abruptly collapsed down on her knees and pressed her big hands into the wall, one on either side of Steve, completely boxing him in. He was desperate to discover that, even on her knees, Melissa was still just about as tall as he was...maybe even an inch or two taller. Still with her arms trapping him against the wall, she bent farther down, bringing her face close to Steve's crotch. Steve felt a surge of arousal as he felt her lips brush his cock through his pajamas.

"Ohhh yeeeaahhhh," she whispered, like she was having a conversation with his cock alone, "We're about to have a LOT of fun together, little guy. Let me take a good look at you while I don't have to squint to see you, haha!"

Melissa swiftly brought her hands down to Steve's pajamas and yanked them down, walking on her knees to close the small space left between them in the process. Steve found himself smushed up against the wall once more, except this time, it was Melissa's big, warm tits that were pressed up on either side of his head. Grinning playfully, Melissa then proceeded to raise herself back up to her full height on her knees, and the effect was that Steve was actually lifted an inch or two off the floor. She was literally pinning him to the wall, suspended in the air, with the force of her huge tits. Now that his legs were dangling, Melissa was able to reach down and whisk off the pajamas crumpled around his ankles. Steve was breathing hard now, as he felt his rock-hard cock pressing into Melissa's soft belly flesh.

"Mmmm, that feels nice!" she cooed in his ear. "You like that, Steve? You like that I'm holding you up off the floor with my tits? Haha, I know you're partial to rear ends...hold on, that's called something, right? Uhhh...oh yeah, an "ass man," haha! I know you're an "ass man, Steve, but my tits aren't too shabby either, are they?"

"N-no..." Steve managed to say. He felt like he was already about to cum, and it didn't help the situation when Melissa grasped him by the hips and lifted him up even higher off the ground, bringing his bouncing cock right in front of her face.

"Yummmm," she murmured, bringing it closer to her mouth as she whispered at it, "I'm almost gonna miss it being this big...gotta kiss it goodbye first!"

*Mwah* *Mwah* *Mwah* *Mmmmmwwwwaaaah*

The sound of Melissa loudly kissing Steve's cock echoed out into the basement, and Steve grasped desperately at her head, trying to stabilize himself as bolts of pleasure coursed through his body with every kiss Melissa planted on his cockhead. He could feel the cum surging in his balls, and the base of his cock began to pulsate and twitch. He was going to cum...he was going to do it...there was nothing that could prevent --

*OLM*

Melissa had suddenly swallowed the entirety of his cock and balls into her mouth, and she had wrapped her powerful lips around the root of his genitals, squeezing and constricting them intensely. In a mad moment, Steve realized that she was actually holding his cum at bay...the constriction from her lips was preventing his orgasm. Steve mewed out desperately into the air, totally abandoning any pretense of self-respect, as he leaned down pitifully against her head. He felt the booming vibrations of Melissa laughing with his cock and balls in her mouth; the vibrations penetrated through every inch of his body, from the tips of his fingers down to the tips of his toes. He felt so incredibly small and tiny -- even something as innocent as Melissa laughing overwhelmed him now. In every conceivable way, she was superior to him...dwarfed him.

*Pop*

Melissa finally freed Steve's cock and balls, but not until she was certain that his orgasm had been denied. She let Steve fall back down onto his own two feet, and he was just able to maintain an unsteady balance as she put her hands back on either side of him, once more trapping him against the wall.

"Uh-uh!" she teased, "You don't get to cum yet, mister! Not until after I make you smaller. That'll teach you to take sex with your stepmother for granted!"

Still on her knees, Melissa backed up a bit, giving Steve a little more room, as she once again lifted up the vial of clear liquid and shook it at him playfully. Steve could only blink helplessly as he stared at it. He was certainly scared about getting smaller, but he would have been lying to himself if he tried to say that he wasn't also excited...perversely thrilled, even, to be shrunken down even tinier.

"Alllllright Steve," Melissa smiled, "It's time! Remember what you're drinking?"

"Uh...n-not...not really," he replied.

Melissa rolled her eyes. "Oh come on Steve, I just told you about it like half an hour ago! A specialized potassium ion compound? Remember?"

"Oh...eh, right...right," Steve nodded.

"And you remember why it'll shrink you?" Melissa pressed on. Steve had to take a moment and appreciate the ridiculousness of the situation -- his 6'6 stepmother, with her knockout tits, giant ass, and goddess-like body, was kneeling in front of him, about to shrink him down to 2 feet tall, and she was actually quizzing him on the biological properties of what was about to happen. Melissa's body had certainly changed, but she was still the same old nerdy scientist who couldn't pass up a teachable moment.

"L-look, Melissa, I...I don't remember all the details, alright?" Steve replied wearily, "Can't we just --"

"Oh my god, you've forgotten already!" Melissa exclaimed. "Come on Steve, this is cutting-edge research we're talking about here! The specialized sodium ions in the multivitamin kickstart the apoptotic process, you know, cell death? Ringing any bells? Haha, anyway...this overrides the protective volume regulatory response, causing the shrinking. And potassium, like sodium, is an alkali metal, with a similar first ionization energy, but potassium is more volatile, and will result in faster shrinking. Come on Steve, don't you remember anything from Biology 101?!"

Steve could only stand there silently, not knowing whether to be indignant or shamed by his stepmother's admonition. More than anything, though, he was still reeling from the intensity of having his orgasm so pointedly denied. His heart was still hammering away in his chest, and Melissa's proximity was only fuelling his lust. Somehow, in a bizarre way, having her lecture him on the biological intricacies of what was about to happen made her seem even hotter.

"Can...can we j-just...just get on with it?" asked Steve in a small voice. He understood the implications of what he was saying, and at this point he couldn't even pretend to hide it any longer. He wanted her to shrink him; he wanted her to make him smaller. The prospect of looking up at her gigantic ass, while he was 2 feet tall, was proving far too enticing to resist any longer.

"Ooooo you really DO want me to do it!" Melissa squealed. "Hahaha oh my GOD that's sooooo cuuuute! Okay, Steve, okay, I won't torture you any longer. Here, open up! And don't move around too much -- I want to make sure I pour in exactly the right dose."

Steve obeyed, opening up his mouth as Melissa took off the stopper and brought it carefully down to his lips. Even though it was hard not to stare at her body, Steve found himself fixated on his stepmother's expression. She was biting her lip in concentration, completely and carefully attuned to her task. It was like she was working in her lab, her razor-sharp focus taking precedence over everything else. Again, Steve found himself strangely aroused by all of this -- even though his mind couldn't quite wrap itself around the reason he knew, deep down, where it came from: his stepmother's care and precision were yet another way that she was superior to him. She had the patience, the grit, and the resolve to be the incredible scientist she was, and Steve knew that he didn't have a chance in hell of matching her in those departments.

'That's why she's there...and you're here...why she looks like that...and you look like this,' said a little voice in his head. But fairly quickly, his attention was usurped by what was actually happening. The potassium ion trickled into his mouth; it had a slightly bitter taste, but it wasn't altogether unpleasant. Steve wondered whether Melissa had spiked it with some kind of flavored compound, to make it go down easier. It tastes almost like grapes...

But just then, almost immediately after swallowing it, the world around him began to grow. The ceiling, the walls, the pool table, Melissa's big body kneeling in front of him...everything looked like it was suddenly expanding dramatically. The effect was extremely vertiginous for Steve, and he stumbled back into the wall, reaching his arms out to brace himself against the wall. Right about this time, Steve realized that the shirt he had been wearing had almost trapped him up backwards. He glanced down and saw that his shirt pretty much covered his entire body, like a huge gown going almost all the way down to his ankles. Blinking rapidly in surprise, Steve looked back up. Even though he had already known what was going to happen, nothing could have prepared him for looking up at Melissa, towering above him, still on her knees. Her eyes had gone wide with delighted excitement, and she put her hands up over her mouth, gasping out in utter glee. In a matter of seconds, the shrinking was over. Steve hadn't even felt anything.

"Ooooooo just LOOK at you!!" Melissa cried. "My precious little man! Hahaha oh WOW...look at this, Steve! I'm on my knees, and you only come up to...oh my god, you only come up to the middle of my stomach!"

It was true; Steve was staring straight forward into the middle of Melissa's toned stomach. Even just watching her breathing showed him how immense her body was compared to his -- the amount of sheer mass that was moving before his eyes, every time she took a breath, was enough to make him feel smaller than he could have ever imagined possible.

"And you feel ok, Steve?" Melissa asked quickly, reaching down and feeling his forehead with the back of an enormous finger. "Nothing out of the ordinary?"

"N-no...no, I feel fine...I...I m-mean...aside from being two feet tall?" he quipped, trying to grin. In truth, though, he was too distracted by his tininess to smile much. Even the sound of his voice compared with hers was striking. Hers had a booming richness to it, and vibrated through his entire body, whereas his voice sounded waifish and meager...almost mouse-like.

"Yes, aside from being two feet tall," chuckled Melissa, rolling her eyes. "Heheh, still a little jokester, aren't you?"

She suddenly pinched the top of his oversized shirt and yanked it straight up off his head. The task was incredibly easy for her, and a moment later, Steve stood there naked before her. Melissa didn't waste any more time. She swept him up in her hands, cupping them under his armpits as she lifted him up off his feet and held him firmly up against the wall. Her wide eyes traveled hungrily over his naked body.

"A delicious...scrumptious, 24-inch little jokester," she breathed at him. "And you're aaaaall mine, little guy. I get to do whatever I want with you now. Mmmmmm, and this is just the start, Steve...just the start."

For several long moments, Melissa simply held him there, suspended off the ground. It was like she was so excited and thrilled that she didn't even know what to do with him first. Several times, she shifted in place, like she was about to get up off her knees, or cradle him to her breast, or set him back down on the floor. Each time, she balked, and it quickly became clear that she simply didn't want to stop holding him. Her hands felt gigantic as they eagerly massaged into Steve's shoulders and neck...everything about her was gigantic to him now. Steve didn't know what he had imagined it would be like to be two feet tall, but whatever his previous thoughts, none of them possibly measured up to the reality of how tiny, how miniscule, how puny he felt in her grasp.

Finally, Melissa got a devious sparkle in her eye.
