You struggle, as she points the remote at you, completely unsure of what she is going to do. She smirks, and presses a button.
You feel your body fill with energy and power. You glance down, seeing your body slightly alter. You watch as the bit of stomach fat you have melts away. You see your pecs growing and feel the tightening sensation in your chest as your muscles slowly gain strength. You look over and see your forearms and hands thickening and slowly lengthening. You watch as your bicep slowly fills up your T-shirt.
"Heather, stop!"
She just smiles, as you feel your feet slowly moving off the bottom of the bed, and you feel the shoes tightening around them. You feel your jeans slowly moving up your ankle, and growing tighter around your thighs and crotch. You shift to attempt to end the discomfort of your growing penis and testicles. You feel a draft hit your stomach as it begins to expose itself.
Just as you think Heather is going to make you as big as possible, she stops. She walks over to you, and begins to undo your restraints. "Now, I'm not sure if you feel it or not, but I put a little device in your ear, rigged to go off at my command."
"What the hell are you doing, what do you want from me?"
"I told you, I love you."
"What? No you didn't. Are you insane?"
"Why does everyone keep saying that?!" She said, annoyed, and then slapped you. "I'm the most fucking sane person in the world, do you hear me?" You were a bit confused, and worried. Heather was hot, but not hot enough to get away with stuff like this. "Now then. That device in your ear is a variation of this remote. It will allow me to alter your size and shape from anywhere in the world, and see everything you see. If you try to remove or destroy it, it will release a final signal, causing you to grow extremely massive. And don't think it would be something you are willing to live with. When I say massive, I mean fucking massive. You'll be a sexy tower of destruction. You will outgrow the world, suffocate in outspace as your body continues to grow and destroys the planet...and maybe even the solar system. I'm not sure, gravity gets weird when objects get that big."
Your arms released, you get out of bed. You aren't sure what to do. You contemplate lunging at Heather and grabbing the remote, but you can't take any risks. You looked at your now imposing, buff form. 6'7", 270 lbs of muscle, your genitals feel so much heavier. "What do you want from me?"
