An average guy who wishes he was bigger

You're not short, at 5'9 you could be taller.

You're not fat, but with no six-pack and slight muscles, you could be stronger.

You're not ugly, but with receding hair and an average face, you're nothing amazing.

You're not exactly small down there. But at 6 inches you could be bigger.

All in all, it could be worse, but you fantasize about being bigger, more attractive, stronger, and more confident. You go to bed and more and more intense images come into your head. Your muscles balloon up, and your cock swells in size. Hot girls **** for you, their tight pussies barely able to contain you as you fill them with gallons of cum.

Well. That's decided what you want to do now as you head to bed and start to play with your now hard cock. You don't realise that every image that you see is being used to inform what the bug thinks is perfect...

Through the Night, things change. Unknown to you, this parasite, the size of a pea crawled up your urethra and down into your testicles. Its body melding with yours and takes over the production of your semen. Tapping into your nerves it feels your desires and starts releasing hormones and chemicals, causing your body to go into overdrive. Your muscles separate and start to swell. Your tissue grows all over your body. Your bones start to stretch and your penis slowly gets thicker and longer through the night.

To fuel these changes, fat is burned off your body as gram after gram disappears. The differences aren't huge, but the hormones this parasite excretes linger, causing constant change. As these changes happen the parasite grows too, swelling and expanding, connecting with your nervous system. Slowly filling your testicles with more and more seed ready to be spread

Your alarm rudely awakens you, you drag yourself out of bed. Your muscles ache and you try to remember when you went to the gym. Going to the toilet, you notice that while you pee your cock feels bigger in your hand, maybe just an inch, or maybe it was just hot last night.

There's no time to think about it as you have to go to work. Quickly dressing everything feels tighter than the day before. The shirt is taunt over your shoulders and your trousers feel like they stretch over your legs while your bulge feels more pronounced. Strange...
