"So, what am I gonna do?" You ask. "I can't just keep growing." You say, looking at the tray that had his blood sample on it. It had more blood than it's original drop, because of the worms dividing before they died.
"They are making you grow because they need more room to grow and divide. If we can make a balance, someway to make it so the worms won't be in such a stable environment that makes it so they can easily divide." Sandra says.
You shrug as Sandra says she is gonna do some tests, and sit down on the far end of the lab as Sandra begins to experiment with your blood sample.
As time slowly stretches on, your body slowly grows. You constantly fidget, and adjust your shrinking clothes as the worms continue to expand in your body.
In the hour and a half of Sandra's tests, your body began to expose more of itself as your clothes couldn't fit anymore. "I'm done, come here let me show you what I did."
You stand up, and walked to Sandra.
She turned around to face you, only to be startled, and jumped back at your new size. "Holy crap those things work fast."
You were almost 6'10", your muscles bulging out of ever possibly area of his clothes. Your pants barely clung onto your waste, and did nothing to hide your now 6 inch long flaccid penis, because your butt and legs grew so muscular, that they made your pants incredibly tight. "Yeah...it's really painful."
"You...you seriously look great." Sandra said, shocking herself a bit.
"Um...ok. Haha." You say, not knowing what to think in this completely odd situation.
"Ok, sorry, look. I gave the worms to several fruit flies. They all died." Sandra said.
"Oh God..." You say.
"No no. They died because they are fruit flies. Nothing these worms make is dangerous to humans. Anyway, enough of the specifics. Let me show you my samples."
There sat 8 dead fruit flies, each bigger than the last. The two were the size of a normal fruit flies. The third was slightly larger, the fourth even larger. They continued on this pattern until the 8th one, which was as big as a regular house fly.
Sandra pointed to the first fly. "This one was the control." She then pointed to the largest. "This one showed that electricity, for whatever reason, accelerate the rate of division and growth in the worms, and thus the division and growth of the host. Each one died about 10 minutes after having the worms, because the worms excrement is poisonous to fruit flies, but not to humans." Sandra pointed to the 2nd fly. "This one didn't grow at all, because I gave it X-rays. The X-rays make it so the worms can't divide. I'm not sure how long this lasts, I assume it lasts until the worms die off."
"So all I need is an X-ray?"
"Yep...but um..." Sandra started blushing.
You paused, and so did she, and there was a silence in the room for a few seconds, which was broken by your jeans giving their final tear, falling to the ground, and your huge penis rolling free, slapping against your muscular thigh.
Sandra stared in awe, and then realized what she was doing, and covered her eyes and looked away. "Wow..." she said, looking down.
"Wow?" You ask.
"I want that...I want that to happen to me. Do you care if I give myself the worms?" Sandra asks.
"Well...I mean, we don't know what these things do...but it's not like I'm the lord of the worms, if you really want them, you'll take them regardless of what I say, right?" You say.
"...Prolly." Sandra replied. You laugh when Sandra pulled out an already prepared syringe, prepared herself, and injected the worms in her body.
Sandra cleaned herself off, prepared everything, and sat down. "My heart is racing..." She said, and you agreed. You couldn't wait to see what Sandra would become. "Now...lets get you X-rays."
