Sandra was the smartest person you have ever known. She was one of those girls that got all those crazy scholarships and stuff while still in high school. She was already in med school, and only 19 years old.
If anyone could find out what was wrong with you, while keeping everything a secret, it was her. You walk over to her dorm, putting on whatever would fit you the best, and knocked on her door.
"Who is it?" She called out.
"It's me, Moe, I got a really big problem, I really need your help. Don't get scared when you see me."
There was a pause, and then the door opened, and Sandra let out a small yelp and jumped backed, noticing your obvious size different. "What the hell?"
"Please, let me in, I don't want anyone to see me." You say.
Sandra stepped aside, and you walk in. Sandra was staring at you pretty hard, when she finally said, "What the hell happened?"
"I don't know, I woke up like this. I think I can still feel it happening."
"Feel it?" She asked.
"Like, I still think I'm growing." You say, adjusting your pants a bit.
"How long ago did you wake up?" She asked.
"Five minutes ago?" You responded.
"And you suddenly got taller and bigger muscles?"
"And bigger...down..."
"Ok ok. Um...let me think. We could take a blood test? I think that's all I can really do... I'm not that skilled."
You agree, and you both get to the lab, staying as low as you can to not draw any attention. You reach the lab, and Sandra begins to prepare to take a blood sample from you.
Sandra was 5'8". She wasn't tone, since she spent most of her time studying, but very attractive regardless. Her ass was slightly larger than average, but still looked great. Her C cup seemed tight on her, because she had recently gained some weight, which almost all went to her butt and breasts. Her brown hair was down past her shoulders, and dark brown eyes matched very well with her light skin.
She took a blood sample from you, and put it under a microscope. There was a long pause, that felt like hours to Moe.
"That...that's incredible." She said.
"What?!" You say loudly, out of frustration.
"Look." She said, and you listen, assuming you wouldn't know what was going on. You see what you assumed were your blood cells, and what looked like 2 worms. One worm would attach to a blood cell, then the blood cell would divide. The worm remained attached to one of the cells, which was now smaller after the division. The cell then swelled to it's original size after a few seconds, then divided again.
"You have some sort of parasite. Well, it's not a parasite, it's more like a microscopic bug has created a symbiosis with you. For whatever reason, it wants you to grow." Sandra says.
You look back in the microscope again, and see the worms look to be almost twice their size. You can actually see the worms getting bigger, and laying eggs.
The eggs hatch, and more worms appear, and attach to your cells. Most of the worms die, and then the process slows down as the blood under the microscope dries out.
"They are dividing extremely fast. I guess they just want more room." You say.
