"You, a little boy."
She held him on her hip, and over the crest of the twin swells of her bosom he saw her bring up an even more intimidating swell of flesh; her bicep, rising up high in the air.
"Worship my muscle..."
Dennis's transfixed eyes focused on her huge, swollen muscle as her fat, chubby fist tightened, her rotund, popeye-shaming forearm bloated, and the broad, loaf-shaped peak of her enormous biceps pushed up higher and higher.
Greta smiled even broader, observing her own huge muscle and feeling the crazy strength contained within. "And my power!" she happily chirped.
"Then you can come, my stupid little captive."
She unceremoniously dropped him to the floor, her face once again disappearing behind the shelf of her bosom, but she held her flex and Dennis could see that giant thing still standing proud above the massive swells of her chest.
She talked down at the invisible boy. Flexing her massive muscle for herself. "and by the way. That's going to take a lot of work. A lot of worship."
She flexed a leg.
"You've got a lot of being a little, mean-spirited twerp to make up for. And I'm a big girl with a lot of surface area to cover. I'm not easy to satisfy, truth be told. I'm really turned on by this body I've got now." She groped a breast, held out far over her sucked in abs, "but you know us fat girls can really fuck, and fuck and fuck." she let it drop. "we know how to get around the block. So you better get fucking started."
She shifted her stance as her marveled at the spectacle of her massive legs moving above him, giving him a better line of sight to her massive bicep. She pointed at it, colliding breast and pec flesh up to her chin.
"Get up here and kiss this bitch."
Dennis's penis was in control now, as he stood up and realized her bicep was far above the reach of his lips. He actually puckered and jumped to reach it, hoping to please her quickly but painfully bouncing his erection in the air as Greta giggled and chuckled, flexing and pumping her arm all the while, taking extra care to tense it up a little higher each time he jumped.
Dennis's senses were overloaded; his mind, gone. The heavy scent of her arousal, her giant bicep sprouting out of that immense, round arm and shoulder. Her beachball-sized tits above the level of his head jiggling like heavy water in a nuclear reactor of sex. Every time he came landed on the wooden floor with a light "thud" and a "creak" he winced as he almost came, the torture imposed upon him by whatever magic Greta was using against him exquisite.
"Greta.... please!" he whined, "I'm not even tall enough to reach your bicep! I need to come so bad! I'm sorry! You're sexy, I admit it! Please!"
Greta smirked down at him. "Aw.. poor average Dennis. Well I guess you'll have to climb." She snapped one band of her overstretched exercise bra, still casually holding her preposterous flex. "Hurry up. She's waiting." Greta flexed her peak a little higher and a vein throbbed over the top.
He looked up at her helplessly. Her still soft, large heart went out to him. For about a second. This was so much fun!
"For a kiss Dennis. Just a kiss. I'm so turned on by my own, superior body now that maybe that will be enough to make me come." She touched a finger at the end of her thick arm to the softness in between her mammoth, bulky thighs and wide-spread muscular hips. "Ooooh..." She cooed, squirming her muscles. "Do you think that will be enough? It sounds like just the first step to me."
Dennis frantically searched the cabin for a chair that wasn't made of some huge animal, something he could move. Everything seemed suspiciously heavy and stuck in place. Finally he spied a three legged stool, almost decorative, and placed it approximately under the fat underbelly of tricep meat that pumped off the bottom of Greta's huge arm.
He placed one foot on the stool, which was barely big enough for it, and gingerly lifted himself up to the levels of Greta's massive, pale skin, balancing himself with one hand on her arm and one her fat left lat muscle as it burgeoned out from her side.
"Stop!" She ordered, giggling again. He was really getting sick of her in some rational part of his brain. "Kiss the underside of my girl first." She again pointed underneath her breasts, this time almost smashing him off the stool with her tits as she brought her finger up to the bloated, vein-laced belly of her relaxed muscle. "Kiss her right here."
Dennis did, his balance wobbly on the stool as he clung to her huge arm for dear life, his sweaty fingers slipping off the hard, bloated curves resting underneath the soft layer of fat that still covered them. He moaned with lust and planted a kiss on the underside of a triceps that, by itself, practically dwarfed his face.
"Now you may proceeed. And hurry up. She's getting impatient." Greta brought her finger up to her bicep and gently stroked it over the top.
Dennis gained purchase in the crook of her elbow, and the crevasse where her monumental beef of shoulder dove into her monumental beef of bicep.
He had to lift himself up on his toes. Bringing himself face to face with a huge, buttery slab of bicep that utterly dwarfed it. He planted a kiss on the underbelly of her bulging muscle, the rounded curve where it stuck out from her arm. She gently squeezed the meat into his face.
"Higher."
He was now almost doing a pull-up, which brought him hard against her muscle like a climber on a rock wall, his eyes crossing as he was now directly in front of a vein that had puffed out of her tremendous mass. He kissed it. It throbbed.
"Higher."
He was now almost at the top of Greta's huge arm, and noticed her bicep was towering up near her fist, almost as tall as she was, even higher than he had thought on the ground.
Greta had been gently stroking and fingering herself, but as he reached the top she took her pointing finger and roughly grabbed his hand away from the crook of her shoulder and swamped it down into her cootch, her hand forcefully working over his.
"Higher. Mmmff.... Higher!"
The stool was wobbling dangerously as his right arm burned and jolts of pain shot through his right hand. Each time she said "Higher" Greta was squeezing her bicep, and his trapped hand was getting crunched inexorably between that and her fat, bulbous forearm, inflating like a car tire.
Trembling, his erection throbbing and bouncing, straining, he hauled himself up to the top her her muscle with every ounce of strength he had left, his body uncomfortably twisted with his left arm down in Greta's moistness and his right trapped in the flesh-vice of her arm.
Then, with the beginning of a peal of laughter that rang throughout the lodge, Greta twisted her fist and shot a second peak of muscle up through the bulk of the first, knocking Dennis's puckered lips back with the force of a punch the mouth, sending the stool flying and him collapsing back to the floor. Crying in pain as his sensitive groin hit with a "Splat!" and the bouncing boner speared up in the air.
Greta popped her new peak a few times by clenching her fist. She again snapped the strap of her exercise bra, wobbling those immense, now hard-nippled tits.
"Better use your hands in a better way this time little man." She popped her bra again. "Better get back on that horse."
She relaxed her flexing arm and daintly plucked two beans from the bowls on the high shelf. One green and one blue, then palmed them and turned back to Dennis, who was gingerly touching his lips. He tasted blood.
"Gosh Dennis. I could swear I was almost there for a minute. But you really do NOT know how to perform with a lady. And it's not going to get any easier from here."
She leaned over slightly in order to see him over her bust and then, grinning, tilting her head back and holding her fist out, cocked the gigantic cannon of her arm, using her thumb to pop one jellybean, blue, and then one, green, flying through the air and into her wide open mouth with magical precision, deftly swallowing each with an exaggerated "GULP."
Letting the magic of the beans work their way through her, she straightened her posture and put her hands on her wide, spreading hips. She swelled up in front of Dennis. Far over his head her breasts pushed out farther and the undercleavage of her fattened tits and plump pectorals thickened, deepened and widened. Her abs, dominating his central focus along with her hips and crotch, bubbled and separated further out into the space below her rack, and her green exercise trunks tightened into the crevasse between her majestic legs as extra ass blew out behind her.
As she rose up and up, more slowly than before, Dennis had never felt more powerless or turned on in his life. The fight or flight reflex was stronger in him now, urging him to either satisfy this immense woman, who was starting to turn, in this extravagant situation, into someone much MUCH more than just "Fatty Gretatty", or to flee for his life, to hide somewhere in this house.. or.. but...
He realized it was hopeless and looked back up at Mt.Greta.
She leaned over again slightly and now pointed up to the space next to her ear, where a huge trap muscle suddenly appeared.
"How is she doing this?" Dennis thought to himself.
"This time you get to kiss THIS muscle. And we saw how well your clever stool worked out last time. Better to climb Mt.Greta this time. In fact." She reached for another blue bean and gulped it down, growing another two inches. "You might need to strap on some gear before it's all done. Ha Ha Ha Ha Ha!!!"
Her mighty chest shook like two bowls of womanly, gelatinous doom. How would he ever get over that? His heart palpitated in time with her booming laughs, and yet, with every ounce of his soul, he now needed release.
