This is my first fic in a while, and it's probably not the best thing ever written, but it is the pilot for my foum's virtual season.
It can be read at http://www.vf11.com/altlyoko/altlyoko-post-11.html#11
As for a maturity rating, I'd rate it no different that a standard CL episode. After all, that is the aim of the entire fic.
Constructive criticism welcome.
