Judy looked at her waist in the mirror, it was cut, the muscles rippled with power, but she looked out of proportion and she realized that she had to fix that. She went over to the power rack and loaded up the bar with as many 100 lb. plates as she could find. Grabbing the framework she hooked her feet under the bar and started doing leg raises. Her abs bulged and swelled, but the workout affected her whole body. With each rep she could feel her lats thickening and her thighs were a roadmap of veins and sinews.
The added effect was working on her in more ways than that. She could feel a pulsating between her thighs. She changed the movement a little to work her obliques and her body responded as she wanted.
"This is better than I thought."she mumbled to herself.
Suddenly the pulsating became a dire need and she dropped the bar. Swinging to the side, she wrapped her massive thighs around the metal framework and rubbed her mound against the cool metal. Something was happening. Her clitoris was throbbing, it was getting hot and throbbing intensely. She rubbed her mound harder against the metal and the framework began to bend. She dropped to the floor crouching looking like a feral beast in heat.
As she tried to stand panting the thoughts came to her mind,"I have to focus! I need more! The more I work my body the bigger will be the release." At that moment the fabric over her mound snapped bringing her back to the incessant throbbing.
Her body was on fire and in some ways newly awakened, as if every nerve was on fire and demanded attention. Grabbing two barbells she loaded them up with the 100lb. plates. With her beach ball sized breasts normal barbell exercises were useless. She lay on a bench which groaned beneath her and began to do dumbbell bench presses and flyes to pump up her pecs. The bra snapped, but was stuck by the cups to her chest. As the blood rushed to her pecs she dropped the barbells, they crashed to the floor. She arched her back and could feel the muscles pulsating, it was fabulous.
As Judy stood, she could feel that her clitoris had thickened and it screamed for attention. She grabbed the barbell/dumbells and performed barbell curls. She raced through lat raises which caused her delts to split and swell. She could feel fluid running from her pussylips. She tried to sit down to do overhead dumbbell presses, but the cool leather on her hot mound made her shake with a desire to release.
One of the guys peeked around the corner to see if she was still there. At that moment he saw a shivering Judy fall to one knee. From behind he could see the massive granite globes of her muscular ass, the muscles rippling beneath the skin. As she convulsed she seemed bigger, but there was something he hadn't noticed before. From between her massive cheeks and thighs her mound was swelling. Fluid was running from her engorged lips. Was that female cum, or pre-cum?
Judy couldn't stop the convulsions, she was so close and yet she wanted to fight it for a little longer. Her clit was demanding attention and it would feel so good. Struggling to her feet she carried all the weights she could gather to the leg press machine. She piled it on anyway she could get it to stay. She didn't care if something fell off, it couldn't hurt her anyway.
Gingerly she slid into the seat and put her feet up on the plate. She slowly began to pump out the reps, it was still too light for her, but her muscles were still getting pumped. The fluid running from her pussylips was exciting her and she started to pump faster. She had to use a wide stance because her breasts would've made it impossible for her to do it the regular way. She let the weight drop back further and the cold metal touched her growing nipples. She felt them react and contract. Her hands began to shake as she felt her mound throbbing harder. Her legs were already enogorged, but the direct workout made them swell faster, rubbing against her throbbing mound.
Judy closed her eyes and her jaw slowly dropped open as she clutched the hand grips and let the rack slide all the way back. The cold metal plate pressed against her huge nipples and her hand shot to her swollen, wet, demanding clit. She came in a gusher. The force was so intense it hit the foot plate sending a shower of her cum back onto her and it was so erotic to her that she laughed. The sled began to move back up and stopped at the end of the track. As she continued to cum there was a creaking sound. Suddenly the sled broke free of the rails and tumbled off the end to an earth-shaking thud.
Jeremy stood in awe as he watched this, this woman stand up to see what she had done. He was rock hard and panting himself as she suddenly turned to see him. Judy had grown a little taller in reaction to the massive orgasm. She sauntered slowly towards Jeremy.
"Did you see that? Did it make you hard?"she drawled sexily at him."Do you want me to get bigger?"
"T-t-that was amazing!"stammered the terrified, excited man.
"Wait'll you see this."said Judy smiling.
She turned slowly and walked over to where she had noticed some oxygen cannisters, the big long ones stacked by the wall. She grabbed one with one hand and proceeded to lay on her back on the floor. She put her legs up and slowly swung them out to the sides so that her mound parted to reveal her swollen lips and first-sized head of her clitoris. She positioned the rounded end of the tank by her lips and they seemed to swell and reach out to the tank. She let go and her pussy slowly sucked in the tank. With nothing more than muscle control she made it move in and out. With her hands free she played with her swollen nipples and waved Jeremy over to her side.
Jeremy walked uneasily over to get a closer look, her erection was straining against the front of his pants.
"So, what do you want? Do you want to have sex with me or should I get bigger, Baby? Choose wisely."she whispered through half closed sensuous eyes.
