See how big it gets...

You notice that the squeeze that you gave your newly super-sized cock made it plumpen a little as more blood began to flow to it. In the bathroom mirror, you can see you cock slowly rise as it grows partially erect just from the one squeeze you gave it.

Curious to see exactly how big this thing will get you wrap your fingers around it and give it another squeeze and then begin to slowly stroke yourself to full erection. You are careful not to go too fast so you don't end up spraying the bathroom with your cum. As your cock seems to get as hard as it's going to get, you can see that it is about a foot long and big enough around that your fingers can't quite reach each other when you hold it.

You glance at yourself in the mirror again, looking at the monstrosity jutting from between your legs. You turn to the side, to see yourself in profile, when you see the bathroom door suddenly swing open.
