Chris first felt a strange tingle spreading out from his stomach, a warm sensation that made him squirm as it moved through his arms and legs. "Wh-What... What's happening?"
That's me! The alien voice echoed in his mind. Or rather, us. I'm spreading through your body, interlacing with your muscles, your bones, your organs. Even your brain! The warm tingle spread into his head while the alien spoke, Chris's dark eyes closing as the voice continued. Like I said before, my people are symbiotes. When we bond with a host, we become them. I am an extension of you, Chris.
The tingling began to subside, coaxing Chris's eyes open. Though he looked no different, he certainly felt different, looking down at his hands. "I... I can feel you inside me. I mean... Us. It feels..." Small smile starting to emerge across his young face. "...Cool."
And we haven't even gotten to the best part!
Chris suddenly wrapped his arms around his stomach, clenching it tight as he felt a strange pulse traveling through his body. It wasn't painful, quite the opposite, another warm wave he could feel running through his veins. It was similar to the feeling before, only hotter. more powerful. Stronger.
"Nngh..." A light grunt escaped his gritted teeth, drowned out by the sound of swelling muscle across his body, feeling the thin white t-shirt hanging from his body pulling tightly against his chest. The arms around his stomach started to swell with muscle, balled fists tensing his forearms and biceps in unison, the hard muscle gaining size with every tiny flex. Already the sleeves were stretched against his shoulders, small tears starting to form when thick cables of muscle filled the collar.
It was his chest that eventually tore through the cotton shirt first, a deep breath between grunts causing his new pecs to pierce the cloth, showing off the shredded chasm running between them that grew deeper with every passing second. Casting a shadow down on the row of abs emerging across his stomach, crunching together as the growing boy's grunts began turning into moans.
"Mmmm...." A thin smile stretched over Chris's pursed lips as his denim pants tried to contain the masses of muscle growing inside them. Tiny tears started to form, showing off the sculpted thighs lurking beneath, hard muscle that fought against its cage as it expanded. His poor shoes didn't last nearly as long, feet bursting free as the sole disappeared underneath them. The cuffs of his jeans had tried climbing up as his body expanded, only to be stopped thanks to his swollen calves, stitches unraveling as the softball-sized muscle continued to grow.
And through it all, Chris smiled. He could feel it, the strength and power he always dreamed about pouring into him, a feeling so divine he almost wanted to cry when he felt it starting to fade. As the now familiar warm tingle died, Chris blinked his eyes open again, staring across the room at the lengthy mirror at his own reflection.
Chris brought a hand up instantly, grabbing the tattered remains of his shirt and tearing it away to expose the physique beneath. It didn't even seem real at first, dragging his (now larger) hand down across his chest, down across one thick pec before it trailed down to his brick-shaped abs. He looked like an anatomy chart, not a drop of fat to obscured his obscene muscularity, fingers dragging up his obliques on their way back up.
"Holy..." Whispering under his breath as he admired his reflection, watching his muscles jump to life whenever he moved. Had to twist his body just to get a better look at his arms and shoulders, as his mirror was no longer wide enough to encompass his entire body. Not [i]this[/i] body, raising an arm with a tight fist so he could watch his bicep and tricep explode when he started to flex. A few thin veins ran from his forearms up across his arms, joined by a couple more emerging the harder he flexed.
His pants were nothing but tattered strips hanging across his legs, Chris tearing them away until they were nothing but a pair of denim shorts barely keeping him decent. Had to get a better look at his quads after all, running his palms down the chiseled columns of muscle. Tapering down at his knees before curving out to his two immense calves, watching them expand like a pair of balloons when he rose up onto his toes.
"This... Is... AWESOME!!" Chris shouted out lifting both arms to the sky in a double bicep flex, feeling the peaks fight for dominance against his forearms. "I look like a bodybuilder! Look at these arms! And my back!" Holding his double bicep flex as he twisted in the mirror, to get a better glimpse of the shredded roadmap of muscle lining his back. "And you made me taller, too!"
Five foot three inches, to be precise! And 220 pounds of rock-hard muscle!
"That's more than Nate..." Chris said to himself, smile growing by another inch as he suddenly remembered his big brother. Nate was athletic himself, but the same amount of muscle on Chris made him look like a small bodybuilder. Not to mention Chris didn't have any bothersome fat to get in the way.
I don't think he's going to be stealing your comic books anymore is he?
"Heck no, I could..." Chris paused with a blink, perplexed look falling across his face. "Wait, how did you know he stole my comics?"
We're bonded! And now I know everything you know, just like you know everything I know. Though I don't think knowing a dozen different alien languages is going to help you much on Earth.
"I know alien languages?" Just as quickly as the words left Chris's lips, a stream of information came flowing through his brain. Strange strings of sounds that would have seemed like a jumbled mess to anyone else, but Chris started to smile again as the knowledge flooded his brain.
"Zyl-Kly-D'lka. Err... I mean, Cool." Momentarily mixing up his English with his Xylese. Chris hadn't stopped admiring his reflection, eventually tearing his attention off his spectacular physique and up to his face. Despite his muscularity, his features still resembled the young boy he was, though it seemed even those had been enhanced and transformed. Blemishes removed, jawline strengthened. And the most curious part, a pair of bright green eyes where his dark browns had once been, brushing his hair back away from his face.
That's from me. I had to extend into every part of you, including your eyes. But if you prefer a different color...
Chris let out a short gasp as the color changed from green to blue in an instant, another small smile starting to emerge when he spoke. "But how did you... Oh, like this?" The blue faded into purple, into fiery red, into absolute black, fluttering through colors at a rapid pace.
Now you're getting it! And this is just the start! What should we do next?
Chris's eyes settled on the color green as he turned from the mirror, lifting his brow in thought...
