Howard, a 25 yr old bodybuilder, and his thin, ...

"Holy shit, Britney, look at her!" Howard pointed to Cassandra standing head and muscular shoulders above the crowd.

"Wow, she's gorgeous, and she has even bigger muscles than you do. Could you imagine Howard, if I was that big?" She mimed flexing and kissing her phantom muscles, giggling. She was cute, thin, pretty and funny, but when she pretended to flex, nothing happened, her arms remained as thin as always.

"Quick, Brit, how much money do you have?"

"Why?"

"Just check!" he responded in frustration as he pulled out his wallet.

"A hundred, maybe a hundred and twenty dollars. What's going on Howard? Aren't we going to see the movie?"

"I've got about 160. Come on, let's go. Hey, mister! It's me, I'm next!" He took Britney's money and combined it with his own waving it in the air while pushing through the crowd towards the salesman.

Howard was an amateur bodybuilder. He'd been training for a few years now and was about to make his contest debut at a local show. He was big, muscular, but he was frustrated with his progress. Sure he was one of the biggest, most muscular guys in the state, but that was small potatoes. He was still so much smaller than the big pros. Even with the drugs he'd recently started taking, his muscles just weren't growing fast enough for his satisfaction. He wore a big green t-shirt that read "Notre Dame Athletic Department XXL".

He was big enough that he could muscle his way through a crowd, pulling Brittney behind him. She was pretty, with long dark hair, and a slim willowy build and a smooth pale complexion. She was a shy romantic girl, into vampires and totally in love with Howard. She'd never dreamed she could have a boyfriend like him, built like a god and so handsome! Sure he treated her like an afterthought, spending most of his time away at the gym, but he that was because he had so much important stuff to do, with his bodybuilding! And the thought of him working out to build his magnificent muscles sent shivers down her spine. She wore jeans and a black t-shirt that read "Forget Princess, I want to be a vampire" on it without a hint of green on her.

"Step right up, sir" the salesman called out to Howard and he walked up to the machine.

"I have.. two.. no three hundred dollars." He shoved the crumpled mass of bills into the man's hands.

"I'll see you in a second Brit. God can you imagine what I'll look like when this is done?"

She started to respond, but she was cut off by the salesman.

"Why not take her in with you? It doesn't cost any more and that way the young lady can get some of the benefits too."

Howard paused and Brit said, "Yeah, I want to go in too! It's half my money you know."

"Brit! I don't want a girlfriend that looks like that giantess we saw earlier!"

"Oh, excuse me sir, but that won't happen here." He lowered his voice. "You see, they were in the free trial phase, and got the full package. You.. well you don't have enough money to get the units they got."

"Yeah Howard. And I know you always wish I was a little bigger. You're so much bigger and stronger than me, don't you sometimes wish you didn't have to be so careful, so gentle during ... you know," she whispered "sex."

It was true, he did wish he could be rougher with her. While Brit did love it rough, he still had to hold back so as not to actually hurt her. Besides, the first girls had grown based on how big they'd been to start with, and he was so much bigger than her, she should barely grow at all.

"OK, OK, come on in." he responded impatiently. They entered the machine, the salesman hit the button, DING! and out they stepped.

Howard came first, twisting his now even broader shoulders to squeeze through the door. His green shirt which now read "Notre Dame Athletic Department XXXXXL" was stretched tightly across his deep, massive chest. He hadn't grown any taller, but where he was muscular before, now he was mind blowingly, freakishly big. He easily weighed 400 pounds and was bigger than the biggest pro bodybuilder. His legs rubbed together when he walked, and he could barely lower his arms to his sides. He did a little fist pump looking down at the changes with a look of ecstasy on his face.

Britney followed, very much in Howard's shadow. She'd changed a little, her arms looked more toned, her breasts a little larger and perkier, but she was really overshadowed by her massive boyfriend. Her t-shirt hadn't changed, although it fit nicely across her perkier breasts.

"Oh my God Howard look at you!" Britney cried out in amazement. "Oh my god, you are so incredible! Holy crap, you're going to win that contest for sure now! Unless..."

Howard barely heard her through his own obsession with his new muscles, but that last part broke through his focus.

"Unless what? No way anyone at that show will be able to top me! I could win Mr. Olympia with this body, never mind the State championships."

"Well, unless one of your competitors sees you and the machine and has more than $300."

He paused for a second and thought about that. "Shit! You're right. I was going to go to the gym to test these new muscles out, but I can't let anyone see me! They'll figure out what I did and anyone can come use this machine! Come on Brit, I have to get back to my place! I can't leave the apartment until the show next weekend!"

He started walking out to the parking lot where he'd parked. His new body felt incredible, heavy and solid and just so massive. He felt like he could barely walk there was so much beefy mass to him now, and he was soon sweating and panting. Brit on the other hand was amazed how light and graceful she felt. Her feet barely touched the ground.

They were soon back at Howard's place. He was really eager to test his new strength, and grabbed one of the dumbbells he had laying around, starting to curl it. His new biceps swelled up to an obscene degree as he pounded out reps. "five... six... sevvvvennnn!" He dropped it to the ground with a heavy THUD.

"Damn! Huh, I guess I just thought. Hmm. Nevermind." His previous personal best at that weight was 10 reps. He wasn't even as strong as he'd been before, the new muscles were just for show! Still, they were crazy huge, which is what he really wanted.

While he was testing himself, Britney grabbed the lightest weight she could find. It felt weightless. Weird, she thought to herself. Why would Howard have something so light around? Well sometimes big strong men have to have light weights to train very isolated small muscles, don't they? She put the weight down and went over to Howard.

"Nevermind, honey, your big muscles are so hot and I am so hot to be here with you. I am so proud to be your girl. My god look at you! My arm looks like a little toothpick! Come here."

She pulled his shirt over his head and walked around behind him, rubbing his abs as she circled around. She grabbed his massive shoulders in her hands and started to massage them.

"Ow! Brit, easy! They must be really tender or something, that really hurt!"

That was odd. She was never able to squeeze hard enough to give him a good massage, it was one of the things she wished she could do. Sometimes she leaned on his thick muscles with her elbows to try to make a dent in them, but it never really did the job. Something funny was going on. She walked over to the weight that Howard was lifting earlier and without a word picked it up.

"Brit! Jesus, careful, you'll hurt yourself!"

But she wouldn't. She started doing curls. Ten, fifteen, twenty, she wasn't even slowing down. When she hit fifty she dropped the weight. Howard watched with shock and amazement as his slender girlfriend banged out fifty reps curling 80 pounds. The fiftieth looked as effortless as the first did.

"Howard, oh my god! I am so strong! That felt like nothing to me. I can't believe it, you got the muscles and I got the strength from the machine!" She was giddy with excitement.

"Oh this is so awesome! You don't have to be gentle with me anymore! I'm strong enough to take it." She walked sexily up to the shocked Howard and pushed him hard on to the bed. He went flying in a heap, his added weight nearly collapsing his bed when he landed on it.

"I'm strong enough to take you, big guy! And oh, I want all of you." She slid onto the bed and effortlessly tore his sport shorts off of him.

"Oh, Howard!" she sighed with a mixture of awe and regret. Apparently it wasn't only Howard's muscles that had grown to an immense size.
