Girlfriend Sally - pt 1

 Sally looked in the mirror at her flexing pecs. They had visible ripples, and a small vein puffed up over her left pec. She wore a blue strappy sports bra and matching blue briefs. She had been pumping some serious iron at the gym, and it showed.

“Oh man, look at me,” she said. “I’m getting really ripped!”

Then she flexed her abs and saw them solidify into a solid six pack. She tilted her hips from side to side, watching the sexy muscles bunch and roll. She ran her hand up and down them and moaned. The sight of her sexy muscles was turning her on.

“Look at these muscles!” she sighed. Then she did a double bicep flex and watched two fists of muscle rise from her arms.

“Ew, Sally,” her boyfriend said from the bed. “That’s gross.”

Sally frowned. She looked sideways at her boyfriend. “What the fuck are you talking about, Erik?”

“Your muscles. It’s too much. You should stop lifting so much at the gym. You’re a girl, but with all those muscles you’re starting to look manly.”

The words hit Sally like a slap across the face. It made her angry. How dare he?

“Fuck you, Erik. I like having muscles.” she said as an angry vein pulsed across her forehead.

“Well I don’t like the way you look. If you keep getting more muscular, I’m not sure this is going to work out between us,” Erik said.

That set Sally off. She walked up to Erik and slapped him in the face. Hard. To her surprise, the strength of the blow knocked him off his feet and to the floor.

“Ouch, Sally, what the fuck??” Erik said, holding his face.

Seeing Erik sprawled on the ground and in pain from a single, open-handed blow sparked something new inside Sally. It excited her. She smiled a vindictive little smile.

“I’ll tell you what the fuck, you little worm,” she said. The excitement welled up inside her as she berated him.

“My muscles are sexy as fuck. I will not stop lifting, you little wimp. In fact, I will lift even heavier, and get even bigger and stronger!”

Erik stood, his hand still held to his face. “You crazy bitch!”

Sally grit her teeth at that last word, and swung a hard backhand against his other cheek. It sent him careening down again.

“Arrghh!” Erik cried in pain as he collapsed on the floor. Sally’s excitement surged.

“Who’s the bitch now, Erik? What’s wrong, you can’t take a hit from a girl?” Sally said. She could feel her crotch getting wet.

She walked over and grabbed his shirt with both hands. She hoisted him up and got right in his face.

“I think you need a demonstration of who’s in charge here,” she said and pushed him, causing him to stumble backward.

Then she tilted her hips forward and flexed her abs down hard. They rippled with six muscular blocks.

“Hit me,” Sally breathed.

“Sally, no..”

“I said hit me, bitch!” Sally snarled as her fists clenched.

Erik had never seen Sally so dominant. He could not resist the command in her voice. He swung lightly and connected with her mid section. His fist hit with a solid “thwack.” Her abs felt hard as a rock.

“Come on, bitch!” Sally said. “Harder!”

Erik frowned and swung again, harder this time. His fist connected with her abs with a loud smack. They were solid. His fist hurt a little.

Sally laughed. “You little bitch. That’s pathetic!”

That made Erik angry. Without being prompted, he swung with all his might. Surprised, Sally managed to flex her abs just as his fist connected. There was a loud slap from the contact.

“Ugh” Sally grunted from the force of the impact. Then she smiled. “I barely felt that.”

Erik’s brow furrowed, and his hand hurt like hell. That was his full strength.

“My turn!” Sally said. Erik’s face turned from confusion to concern. He flexed his own flabby abs as hard as he could.

Sally swung a solid right fist into Erik’s mid section. Her fist penetrated deep. Erik doubled over in pain and collapsed. Sally immediately felt a rush. He cunt spasmed and gushed enough juice to make a wet spot on her briefs.

Sally smiled a sadistic little smile.

“Now here’s what is going to happen,” she said. She grabbed Erik by the hair and dragged him up. She looked him directly in the eye. “You are not going anywhere. I’m in charge now, and you’re going to worship these muscles!”

She tore off her sports bra. At one point, she had nice round b-cup breasts. However, due to her heavy weight training, she now barely had breasts at all. She had transformed her chest into solid blocks of pectoral muscle.  She flexed her chest and slammed his head into her right pec. His head bounced off the solid muscle like it was hitting concrete. He stumbled like he was dazed. She shoved him onto the bed.

Sally put her hands on her hips and flexed her quads. Tear drop shaped muscles bulged from her legs. She licked her lips. She flexed her left pec, then her right.

“My muscles are bigger and harder than yours,” Sally said. “I’m so much stronger than you now, Erik!”

She flexed her abs and the clenched into a rock solid six pack. She held the flex and grit her teeth. Little veins started coming to prominence among the blocks of her abs.

“My abs are like steel!” she hissed. She slammed her fist into her abs with a loud slap. “My pecs are rock hard!” she said and slammed her fists against her pecs. It sounded like a boxer punching a solid wall of meat.

Erik was staring at display with his mouth wide open. He looked like he was about to gag. Sally saw his dismay and it made her even more horny. It made her want to push it even farther.    

“That’s not all Erik. I’m not done. I’m going to work out even harder now, and I’m going to make these muscles grow even bigger!” she said maniacally as she flexed into a most muscular pose. The vein on her forehead puffed up, and her pecs, abs, shoulders and biceps practically vibrated with growth.

Erik gagged. He could hardly believe his girlfriend’s transformation into this muscular thing. On the one hand, she looked so strong and vigorous. On the other, she looked somehow... not right. She was not the girly girl he had been dating.  It confused him.

Sally released her flex and stepped toward the bed. She grabbed his collar with both hands and literally tore the shirt from his body. Then she grabbed his jeans and ripped those off, too. Erik lay naked on the bed but for his briefs. To his surprise, and Sally’s delight, he had a raging erection tenting his briefs.

Sally smiled a predatory grin.

“Well look at that. Maybe you don’t like my muscles, but your dick sure does!”

Erik looked down at his raging erection. It felt like his own body had betrayed him. Then he looked up at Sally, who stood half naked in all her muscled glory. He felt flushed. She looked… sexy.

Sally reached out and tore off his briefs with a flick of her powerful wrist.

“Masturbate,” Sally commanded. Then she did a double bicep flex as fist-sized balls of muscle rose from her arms.

Without thinking, Erik slipped has hand around his shaft and started stroking his cock.

“That’s right, Erik. Masturbate to my muscles,” Sally said. She struck a side chest pose and her pec solidified into a striated block of muscle.

Erik continued stroking. He stared mesmerized at her muscular display. Sally shifted into a lat spread. Wings of muscle spread out from her back like the hood of a cobra. It was intimidating and somehow smoldering hot at the same time.

“Faster!” Sally cried. She inhaled, and sucked her stomach into her spine. Then she exhaled and solidified her chest, lats, and abs into striated fury. Veins puffed up all around her body as she grit her teeth and flexed hard.

Erik stroked faster.

“FASTER!” Sally cried. She stuck out her right thigh and flexed the mighty quad muscle. At the same time, she locked her arms behind her in a triceps pose. Her tricep bunched and bulged off her arm. Her striated thigh quivered and vibrated, and veins started pulsing all over her legs.

Erik stroked faster and faster. He started to moan involuntarily. “Oooohhh!”

“THAT’S RIGHT ERIK, BLOW YOUR LOAD ONTO MY MUSCLES!” she screamed and flexed down into a most muscular pose. Her chest had a notched groove down the center, and striated grooves splitting them horizontally. Veins puffed up and spidered from her neck, down her chest, and across her arms. Her traps flared and climbed her neck like two miniature heads.

Erik stroked his cock like a man possessed. Faster and faster until he moaned, “I’m going to cum!”

“OH FUCK YEAH,” Sally screamed. She was so hot and horny from the thought of making Erik masturbate, of being in control and forcing him to beat off  to her hard sexy muscles. She clenched harder. Her muscles vibrated and her veins engorged. Sweat poured from her brow and dripped onto her chest. Her skin became beat red. It looked stretched out and ready to burst.

Erik could take no more. He came with the force of a geyser and spewed cum all over her vibrating chest muscles.

When Sally felt the cum hit her chest, she too lost control. “FUUUCK YESSS!!!!” she screamed as she orgasmed fiercely and filled her briefs with her cum.  

Panting wildly, Sally said, “And that was just the beginning!”
