Six hours had passed since you had inhaled the parasites, and they had burrowed in all parts of your body, and slowly began to build upon his body.
As the day went by, you were feeling better and better. The usual fetigue of a lazy college student seemed to slowly drift away from you as the day went on. Your eyes no longer felt like they should be closed, your back didn't hurt, and you didn't lose his breath running up the stairs.
You open your dorm room door, and saw your roommate, John, sitting with his friend, Tim.
"Sup Moe." John said.
"Hey." Tim gestured.
"Sup guys." You say, as you throw your backpack on the ground, and went straight to the fridge. You were a lot more hungry than usual.
You and John were only friends because you had to be roommates. You two share none of the same interests. You didn't even like shows John watched. But John knew you enough to know that you don't look this happy and energetic all the time. "You look happy." John started. "You get laid or something?"
You laugh a bit, and Tim responds, "Yeah right. The only action Moe got was from his mom when he was born."
Tim laughed like this was the best joke in the world, and John let out a fake chuckle out of pity. You stood up straight and gave Tim a blank stare. Tim sighed, and looked down, knowing he just embaressed himself making such a bad joke.
You didn't like Tim at all. He was the typical jock type that is only in school because his parents are making him, and paying for it. He's the type that would fail all his classes because he partied too much, and then just work at his dad's business, take that over after his old man passed away, then run that business into the ground.
You then went back toward the fridge, shoving anything into your mouth and hands to take back to his room.
"What a fatass!" John said, jokingly.
You retorted. "You're just jealous of my awesome physique."
You and John always called each other fat, as a joke, even though neither of you were fat.
You ate the massive meal. You hadn't eaten that much in....ever. This, of course, made you sleepy, and you fell asleep.
And that was the moment the worms within your body began to work and making more room for their population to grow. They somehow unfused your growth plates, and began to deposit calcium and other minerals to encourage bone growth.
You slowly grew taller in your sleep.
Then the worms in your muscles began to tear the muscles, and added protein and mass, slowly building your muscle.
Your biceps slowly built up, and your forearms matched the pace. The average amount of fat on your torso slowly melted away as the worms used the fat to create more muscle, as your abs began to take shape and show, growing larger and larger. Your pecs slowly ballooning outward in all directions, twitching as they formed. Your legs and buttocks followed suite, melting away the fat, and tightening with muscle.
The worms even drifted into Your genitles. They built more and more mass for the penis to fill up with more and more blood, and added to the testicles, which, ironically, was only used for storing their own eggs.
Finally, your flaccid penis slowly lengthened, snaking downward from its normal 1.5 inch flaccid state.
You were now 6'5", and built like a fitness runner. Your muscles hadn't grown big enough for people to notice unless you took off your clothes, and your penis went from an average 1.5" soft 6" hard, to a 3" soft, 9 inches hard.
This all happened in the span of an hour, and you woke up from your nap, feeling completely refreshed. You stand up, feeling an oddness around you and a sudden lack of a balance. You looked in the mirror, and jumped back at the image you saw, your clothes smaller and tighter around his body.
