After the snake had bitten me, my entire body seized up and my arms became locked at my sides and I could was wait.
I heard a loud ripping sound coming from below me. I looked down in time to see my feet burst through both my shoes and socks, growing to nearly three times their original size and digging the rubber into the forest floor. I continued to watch as the energy flowed from my feet and into my legs. Just as with my feet, my legs began to grow; pulsing and retreating, expanding and contracting until my shorts could not take the pressure anymore. Finally my shorts were shredded to bits with a satisfying RRRRIIIIIIIPPPP! I looked down at new telephone poles that had sprouted from beneath my torso. Calves as thick as the Hope Diamond and just as hard were perched on top of feet the size of shoe boxes, and perched on those were thighs as wide as tires. The energy didn't stop there, however, and made its way up my spine, curving it slightly, and into my arms, creating a vast system of veins that snaked their way down my skinny arms and onto my hands. The growth began in my shoulders as they burst with muscle once, twice, and then three times; erasing my sleeves from existence and growing to the size of medium beach balls. Next came the biceps, and I watched in a mixture of shock, horror, and joy as the muscle fought for space on his once tiny arm. Just like my shoulders, my biceps ballooned three times before finally resting at the size of basketballs. The growth continued the same for my forearms as two horseshoes formed under my skin. Finally my hands joined the growthapalooza as each finger lengthened and thickened; becoming sausages while my palms expanded to the point where I could hold softballs and still have room for more. The energy began to move once again and flowed into my chest. Just as with my legs, I could see my pecs heave in and out, pushing the very limits of my shirt. After a few moments of this tug-of-war, my back joined in, widening my body so much that my shirt had no chance. It burst from my skin with the same satisfying RRRRIIIIIIPPPPP as before. This didn't slow the growth down one bit. I continued to become wider as my lats flared to the sides and my pecs forced their way into the airspace in front of my chest. The growth may have stopped, but the energy did not. It eventually resided in my stomach. The energy didn't stay there for long as it slowly made its way towards my head. As the energy continued its course, I watched as two packs of abs burst from my stomach in its wake, followed by a second row, and third, and finally a fourth; creating a solid eight pack of abdominals and obliques that could stop even a punch from professional wrestler. As the energy continued to move upwards once again I watched as my already small waist shrank almost an inch on either side. The resulting v-taper created by my expanded back and small waist was so wide that there's no comparison to its width. Finally, the energy came to a rest in my neck as my traps rose up higher and higher, eventually reaching his ears and creating a pyramid with my head as its tip.
The energy finally disappeared and I was free to move again. My first bout of movement was to raise my hands high into the air, feeling the weight of my new arms, and bringing them down into a mighty double-bicep which caused my already sizeable biceps to explode off of my arms with sheer power and strength. I began to feel the rest of my new body. As I reached my pelvic region, I felt one last spark of energy fly into the last bit of shorts that had survived and into my member. I felt a mixture of intense and euphoric joy and eroticism as I watched my shorts expand further and further until a one foot fire hose burst out attached to large baseballs that dangled between my thighs.
As I gazed upon his my new member, a fit of euphoric and erotic pleasure let loose a beastly RRRRROOOOOOOAAAAARRRRRR and pounded my concrete chest with my godly arms. I completed my primal burst and began to huff and puff, but not out of exhaustion, to watch my pecs rise and fall in front of my face.
"Good. We finally got the right one and I can finally change back to my true form." Right after that the snake had quickly grown to my size with arms, legs, muscles and a member of its very own with his tail completely erased.
"Okay." I blurted out to the snake. "I admit that this change was amazing, but why me? Where did that roar come from? Not to mention who are you and who is we?"
"I'm not surprised you have all these questions." The snake said as he crossed his arms. "Your father had asked the same questions."
"My father!?! My God this is crazy."
"Don't worry. If you come with me all your questions will be answered. You can choose not to come but you may have to restart your life. I'll be waiting right over there." he said as he pointed to a nearby lake.
As the snake walked away, I had sat down on the forest floor near where the remains of my shreded clothes were laying. I hadthought about what that snake had said. "Well I guess the decision is obvious."
